CERTIFIED AVIATION SERVICES Before DYK, SCHALL, and O’MALLEY, Circuit Judges. Opinion for the court filed by Circuit Judge SCHALL. Opinion concurring-in-part and dissenting-in-part filed by Circuit Judge DYK. SCHALL, Circuit Judge. This is an appeal from a final judgment of the United States District Court for the Central District of California in a patent infringement case. EcoServices, LLC (“EcoServices”) sued Certified Aviation Services, LLC (“CAS”) in the district court for infringement of two patents pertaining to washing airplane engines: U.S. Patent No. 9,162,262 (“the ’262 patent”) and U.S. Patent No. 5,868,860 (“the ’860 patent”). Following a trial, the jury returned a verdict (1) that CAS infringed claims 1, 9, and 14 of the ’262 patent; (2) that claims 1, 9, and 14 of the ’262 patent are not invalid; and (3) that CAS willfully infringed claims 1 and 2 of the ’860 patent, which expired on May 31, 2016, before trial. The jury awarded EcoServices damages in the amount of $1,949,600. In due course, the district court de- nied various post-trial motions by CAS pertaining to the eligibility for patenting of the asserted claims of the ’262 patent under 35 U.S.C. § 101 and pertaining to the validity and infringement of those claims. The court also denied CAS’s post-trial motions arguing that claims 1 and 2 of the ’860 patent, the patent’s sole claims, are indefinite 1 and were not infringed. Finally, the court denied CAS’s chal- lenge to the damages awarded by the jury and its chal- lenges to the court’s supplemental damages award of $175,000 and the ongoing royalty rate set by the court for the ’262 patent. Following the entry of judgment, CAS 1 Even though the ’860 patent has expired, when ref- erencing it, we use the present tense. Case: 19-1602 Document: 67 Page: 3 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 3 timely appealed. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(1). For the reasons stated below, we hold that claims 1, 9, and 14 of the ’262 patent are eligible for patenting, that the district court did not err in its construction of the term “in- formation detector” appearing in those claims, and that those claims are not invalid and were infringed. We there- fore affirm the judgment of infringement of claims 1, 9, and 14 of the ’262 patent. For the reasons stated below, we also hold that claims 1 and 2 of the expired ’860 patent are not indefinite and were infringed. We therefore affirm the judgment of infringement of the ’860 patent. 2 We also hold, however, that the district court abused its discretion in awarding supplemental damages and an ongoing royalty based upon a rate of $400 per infringing engine wash. Ac- cordingly, we vacate the district court’s supplemental dam- ages award and its determination as to an ongoing royalty. The case is remanded to the district court for a redetermi- nation of the proper supplemental damages and ongoing royalty. BACKGROUND I. After a jet engine is operated for an extended period of time, foreign particles and/or contaminants build up inside the engine. ’262 patent col. 1 ll. 52–54. This results in less engine power output; to compensate, the engine has to work harder and burn more fuel, which increases its inter- nal temperature, shortens engine life, costs more, and pro- duces more greenhouse gases. The ’262 patent and the ’860 patent are directed to systems used to wash the inside of a jet engine to remove contaminants. 2 CAS has not challenged the jury’s verdict that CAS’s infringement of the ’860 patent was willful. Case: 19-1602 Document: 67 Page: 4 Filed: 10/08/2020 4 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES The ’262 patent is titled “Automated Detection and Control System and Method for High Pressure Water Wash Application and Collection Applied to Aero Compressor Washing” and issued on October 20, 2015. The ’262 patent describes a system for automatically controlling a washing procedure according to the requirements of the particular engine being washed. Id. at col. 5 ll. 18–22, col. 6 ll. 35–46. According to the ’262 patent, it is disadvantageous for a hu- man operator to manually set up the cleaning system and control its operation because “the human factor jeopardizes the result.” Id. at col. 3 ll. 44–58. This is particularly so, the ’262 patent explains, because “many engine washing operations are performed during night-time when the op- erators may not be fully alert.” Id. at col. 3 ll. 58–60. The specification explains that “[i]t would therefore be benefi- cial for such a closed loop washing process if the influence of the human factor is minimized as much as possible.” Id. at col. 3 ll. 65–67. Independent claim 1 of the ’262 patent recites: 1. A system for washing turbine engines com- prising: a washing unit for providing a washing liquid to the turbine engines; an information detector configured to gather information related to engine type; and a control unit configured to accept the infor- mation related to engine type from the information detector and to determine a washing program to be used as a function of the information relating to en- gine type from a set of preprogrammed washing programs, and further configured to regulate the washing unit according to washing parameters as- sociated with the washing program used. Id. at col. 8 ll. 35–47. Claim 9 depends from claim 1 and additionally requires that “the information provided by the information detector is used by the control unit to regulate a washing time.” Id. at col. 9 ll. 11–13. Independent claim Case: 19-1602 Document: 67 Page: 5 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 5 14 is similar to claim 1, but recites that the information detector can provide information “identifying at least one of washing unit and engine type.” Id. at col. 10 ll. 14–26. The ’860 patent, titled “Method of Washing Objects, Such as Turbine Compressors,” is directed to a method of washing turbine compressors using small quantities of finely-divided liquid that are sprayed through the engine. Independent claim 1 recites: 1. A method of washing turbine compressors, which operate with large quantities of air and therefore become internally soiled by and coated with contaminants carried by the air, therewith giving rise to greater fuel consumption, higher tem- peratures and higher emissions with substantially impaired efficiency as a result thereof, wherein small quantities of finely-divided liquid are sprayed onto and through the turbine compressors, characterized by running the turbine compressors and spraying the finely-divided liquid quantities through at least one nozzle towards and through the turbine compressor at an overpressure within the range of 50–80 bars and at a liquid particle size in the range of 250–120μm, and with a total volu- metric flow through the nozzle or nozzles within the range of 0.5–60 l/min., and with a liquid parti- cle velocity of 100–126 m/sec., whereby the liquid is finely-divided to a degree at which the particles of liquid will follow the same routes through the tur- bine compressor as those previously taken by the air-borne contaminants, when spraying said liquid onto and through said turbine compressor. ’860 patent col. 3 l. 17–col. 4 l. 16. Dependent claim 2 re- quires “using a total volumetric liquid flow within the range of 2–60 l/min.” Id. at col. 4 ll. 17–18. Case: 19-1602 Document: 67 Page: 6 Filed: 10/08/2020 6 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES II. EcoServices sued CAS in the Southern District of Flor- ida for infringement of the ’262 and ’860 patents through CAS’s use of the Cyclean® Engine Wash system (“Cy- clean®”), which was developed by Lufthansa Technik AG. The case was later transferred to the Central District of California. In its claim construction order, the district court re- jected CAS’s proposed construction of the ’262 patent claim term “information detector” that required that the “infor- mation detector” must receive information from an “infor- mation unit,” such as an RFID chip. Order re: Claim Construction of Disputed Terms, EcoServices, LLC, v. Cer- tified Aviation Servs. LLC, 16-1824-RSWL-SPx, Dkt. No. 80 (May 18, 2017), at 10–12. In doing so, the court stated it was “declin[ing] to import a limitation into the claims from a preferred embodiment.” Id. at 12. Instead, the court accepted EcoServices’ proposed construction, which was to use the term’s plain and ordinary meaning. See id. The district court also determined that CAS had failed to prove by clear and convincing evidence that the ’860 patent claim term “small quantities of finely-divided liquid” was indefinite. Id. at 10. A jury trial began on June 26, 2018. As noted, in its July 2, 2018 verdict, the jury concluded that (1) CAS in- fringed claims 1, 9, and 14 of the ’262 patent, (2) claims 1, 9, and 14 of the ’262 patent were not invalid, and (3) CAS willfully infringed claims 1 and 2 of the ’860 patent. The jury awarded EcoServices damages of $1,949,600 for the infringement of both patents, which corresponded to $400 per engine wash that CAS had performed through the end of December of 2017, the parties’ original trial date. After the verdict, in an October 26, 2018 Order, the court denied motions by CAS to: (1) declare the claims of the ’262 patent ineligible under 35 U.S.C. § 101; and (2) declare the claims of the ’860 patent indefinite. Order, EcoServices, LLC, v. Case: 19-1602 Document: 67 Page: 7 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 7 Certified Aviation Servs. LLC, 16-1824-RSWL-SP, Dkt. No. 293 (Oct. 26, 2018), at 12–21, 24–29 (“Post-Verdict Order”). In its eligibility analysis under § 101, the district court analyzed claims 1, 9, and 14 of the ’262 patent using the two-step framework set forth in Alice Corp. Pty. v. CLS Bank, Int’l, 573 U.S. 208, 217–18 (2014). The court noted that, as was the case in McRO, Inc. v. Bandai Namco Games Am. Inc., 837 F.3d 1299, 1314 (Fed. Cir. 2016), “the [asserted] claims of the ’262 patent seek to automate a task previously done by humans.” Post-Verdict Order at 17. Ac- cordingly, “the question is whether the automation pro- vides an improvement to the relevant technology used in airline engine wash systems.” Id. The court held that the control unit’s “specific configurations to regulate the wash- ing unit” provided such an improvement over human oper- ation, similar to how the claims in McRO focused on “specific rules.” Id. at 18. Accordingly, the court held the asserted claims were not directed to an abstract idea under step one of Alice, but instead were patent eligible “because they are directed to improving the process of washing tur- bine engines.” Id. at 20. The court reasoned that “while it is undisputed that there is some level of automation in the ’262 Patent, . . . the claimed process does not use a com- puter to implement an abstract idea, but rather it uses technology to improve the narrow industry of turbine en- gine wash systems to ensure quality, performance, and safety.” Id. at 14–15. The district court’s analysis of whether the ’860 patent was invalid due to indefiniteness was directed to the claim term “at a liquid particle size in the range of 250–120μm.” CAS had argued that the ’860 patent “fails to identify how many particles must fall within the claimed range to in- fringe.” Id. at 26–27. The district court pointed to testi- mony by EcoServices’ expert indicating that at least 35% of the droplets used in CAS’s system fell within the claimed range. Id. at 28. The court found CAS had failed to put forth clear and convincing evidence that one skilled in the Case: 19-1602 Document: 67 Page: 8 Filed: 10/08/2020 8 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES art would not know the boundaries of the claims. Accord- ingly, it denied CAS’s motion to declare the claims of the ’860 patent indefinite. Id. at 29. In the Post-Verdict Order, the district court also denied EcoServices’ motion for a permanent injunction. Instead, the court ordered that the parties negotiate an ongoing roy- alty rate for CAS’s continued infringement of the ’262 pa- tent that was not less than the $400 per engine wash rate awarded by the jury. Id. at 31–45. In addition, the district court awarded EcoServices supplemental damages of $175,000, or $400 per engine wash, for the 314 engine washes CAS performed in the period between the parties’ original trial date and the jury verdict. Id. at 58–60. Thus, exclusive of the ongoing royalty, the total damages award to EcoServices was $2,124,600 ($1,949,600 in damages awarded by the jury, plus supplemental damages of $175,000 awarded by the court). On May 7, 2019, the district court denied CAS’s Motion for Post-Judgment Relief. See Order, EcoServices, LLC, v. Certified Aviation Servs. LLC, 16-1824-RSWL-SP, Dkt. No. 315 (May 17, 2019) (“Post-Judgment Order”). As relevant to this appeal, in the Post-Judgment Order, the district court (1) denied CAS’s motion to amend the judgment as to the eligibility of the ’262 patent under § 101; (2) denied CAS’s motions for renewed judgment as a matter of law or a new trial as to infringement and invalidity of the ’262 pa- tent; (3) denied CAS’s motion for renewed judgment as a matter of law or a new trial as to infringement of the ’860 patent; (4) denied CAS’s motion to amend the judgment as to the indefiniteness of the ’860 patent; and (5) denied CAS’s motion to amend the judgment or for a new trial as to the ongoing royalty rate. CAS had argued that the court’s eligibility analysis in its Post-Verdict Order had improperly relied upon un- claimed components of the claims as construed by the court’s Markman order. Rejecting CAS’s argument, the Case: 19-1602 Document: 67 Page: 9 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 9 district court stated that that its prior Post-Verdict Order regarding eligibility under § 101 “was primarily based on how the ’262 patent’s claims as a whole improve on prior art by eliminating human error.” Post-Judgment Order at 12. In rejecting CAS’s motions for renewed judgment as a matter of law or a new trial as to infringement of the ’262 patent, the district court rejected CAS’s argument that the record lacked substantial evidence that Cyclean® includes the claimed “information detector.” Specifically, the dis- trict court pointed to EcoServices’ expert’s testimony that a keypad used by Cyclean® satisfies this claim element and CAS’s expert’s testimony that Cyclean®’s keypad sends signals to the control unit to initiate the program for a wash. Id. at 14–15. In denying CAS’s motions for renewed judgment of law or a new trial for invalidity of the ’262 patent, the district court rejected CAS’s arguments that claims 1, 9, and 14 are invalid as obvious under 35 U.S.C. § 103(a) in view of the combination of two prior art references, Leusden 3 and Han- sen. 4 The district court noted that the parties’ experts 3 Christoph Pels Leusden, et al., Performance Bene- fits Using Siemen’s Advanced Compressor Cleaning Sys- tem, J. of Eng’g for Gas Turbines & Power (Oct. 2004), J.A. 2050–56.

CERTIFIED AVIATION SERVICES provided conflicting testimony, but that the jury was free to find EcoServices’ expert more credible. Id. at 16–18. Addressing CAS’s challenge to the court’s minimum on- going royalty rate of $400 per wash, the court stated that it had provided the parties the opportunity to meet and to confer and agree upon an ongoing royalty rate and that it would not now reconsider the minimum rate it had previ- ously set. Further, the court pointed to evidence in the form of EcoServices’ expert’s testimony that he had “con- sider[ed] the economic life of both . . . patents” when providing his $400 per wash rate. Id. at 35. DISCUSSION I. We review denials of post-trial motions for judgment as a matter of law and for a new trial under regional circuit law. TEK Global, S.R.L. v. Sealant Sys. Int’l, 920 F.3d 777, 783 (Fed. Cir. 2019) (citation omitted). The Ninth Circuit reviews an order denying judgment as a matter of law de novo; the district court’s determination must be affirmed if substantial evidence supports the jury’s verdict. Id. (cita- tion omitted). The Ninth Circuit views the evidence in the light most favorable to the nonmoving party, here EcoServices, and draws all reasonable inferences in that party’s favor. See Josephs v. Pac. Bell, 443 F.3d 1050, 1062 (9th Cir. 2006) (citing Reeves v.

Case: 19-1602 Document: 67 Page: 12 Filed: 10/08/2020 12 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES CAS challenges the district court’s rulings with respect to claims 1, 9, and 14 of the ’262 patent on eligibility, claim construction, obviousness, and infringement. CAS also challenges the district court’s rulings with respect to the definiteness and infringement of claims 1 and 2 of the ’860 patent. Last, CAS challenges the district court’s award of supplemental damages and a reasonable royalty. We ad- dress each issue in turn. II. A. The Supreme Court has deemed certain categories of subject matter, including abstract ideas, ineligible for pa- tent protection under 35 U.S.C. § 101. Alice, 573 U.S. at 216–18; Mayo Collaborative Servs. v. Prometheus Labs., Inc., 566 U.S. 66, 70 (2012). “The ‘abstract ideas’ category embodies the longstanding rule that an idea of itself is not patentable.” Alice, 573 U.S. at 218 (internal quotation marks and citation omitted). To determine whether claimed subject matter is patent-eligible, we apply the two- step framework set forth in Alice. First, we “determine whether the claims at issue are directed to a patent-ineli- gible concept,” such as an abstract idea. Id. Second, if the claims are directed to a patent-ineligible concept, we “ex- amine the elements of the claim to determine whether it contains an ‘inventive concept’ sufficient to ‘transform’ the claimed abstract idea into a patent-eligible application.” Id. at 221 (quoting Mayo, 566 U.S. at 72). B. CAS contends that our step one analysis of what the claims of the ’262 patent are “directed to” should be guided by our decisions in ChargePoint, Inc. v. SemaConnect, Inc., 920 F.3d 759 (Fed. Cir. 2019), cert. denied, 140 S. Ct. 983 (2020), and Chamberlain Group, Inc. v. Techtronic Indus. Co., 935 F.3d 1341 (Fed. Cir. 2019), cert. denied, 2020 WL 5882260 (Oct. 5, 2020). Specifically, citing Chargepoint, Case: 19-1602 Document: 67 Page: 13 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 13 CAS argues that we should look to the specification of the ’262 patent to understand “the problem facing the inven- tor.” Appellant’s Br. 24 (quoting 920 F.3d at 767). CAS contends that here this “problem” was human error in the conventional engine washing process. Id. In addition, pointing to Chamberlain, CAS urges us to consider how the ’262 patent specification describes differences over the prior art. Id. (quoting 935 F.3d at 1346–48). The only dif- ference over the prior art set forth in the ’262 patent, CAS argues, is that the claimed invention uses a generic com- puter instead of a human operator. Id. Accordingly, CAS contends that claims 1, 9, and 14 of the ’262 patent are “di- rected to the abstract idea of using a generic computer to automate the conventional washing process traditionally performed by human operators” and that the claimed in- vention “is simply the idea of using a computer to replace human operators in a known process.” Id. at 30–31. This is abstract, CAS argues, because under OIP Technologies, Inc. v. Amazon.com Inc., 788 F.3d 1359 (Fed. Cir. 2015); Intellectual Ventures I LLC v. Capital One Bank, 792 F.3d 1363 (Fed. Cir. 2015); and Bancorp Services, LLC v. Sun Life Assurance Co. of Canada, 687 F.3d 1266 (Fed. Cir. 2012), reliance on a computer to perform routine tasks more quickly or more accurately does not render a patent claim eligible for patenting. Appellant’s Br. 23–27. CAS next contends that claims 1, 9, and 14 of the ’262 patent do not recite any inventive concept under step two of Alice. Specifically, CAS argues that the claims do not recite either an inventive function or an inventive struc- ture, since they merely recite the use of a generic washing unit, a human machine interface (information detector), and a computer (control unit). Appellant’s Br. 31–35. Regarding step one of Alice, EcoServices responds that the district court properly found the claims of the ’262 pa- tent not to be directed to abstract subject matter. EcoServices urges that the claims are “directed to systems that use certain hardware in a non-conventional manner to Case: 19-1602 Document: 67 Page: 14 Filed: 10/08/2020 14 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES reduce errors and create a technologically improved tur- bine engine washing system.” Appellee’s Br. 33. This is patent eligible, EcoServices contends, just as “systems and methods that use inertial sensors in a non-conventional manner to reduce errors” in calculating the location and orientation of an object were held patent eligible in Thales Visionix Inc. v. United States, 850 F.3d 1343, 1347 (Fed. Cir. 2017). Appellee’s Br. 28–33. EcoServices also contends that the claims embody an inventive concept under Alice step two. This is so, EcoServices urges, because the components are not generic but are instead configured in an “inventive combination.” Id. at 35. Moreover, EcoServices argues, CAS did not pre- sent evidence at trial to establish that the claim elements at issue were well-understood, routine and conventional. Id. at 36. C. At step one of the Alice framework, “we look to whether the claims ‘focus on a specific means or method that im- proves the relevant technology or are instead directed to a result or effect that itself is the abstract idea and merely invoke generic processes and machinery.’” Cardionet, LLC v. Infobionic, Inc., 955 F.3d 1358, 1368 (Fed. Cir. 2020) (quoting McRO, 837 F.3d at 1314). We also consider the patent’s written description, as it is “helpful in illuminat- ing what a claim is ‘directed to.’” Id. (quoting Chamberlain, 935 F.3d at 1346); ChargePoint, 920 F.3d at 766. As noted, CAS contends that claims 1, 9, and 14 of the ’262 patent are “directed to the abstract idea of using a ge- neric computer to automate the conventional washing pro- cess traditionally performed by human operators” and that the claimed invention “is simply the idea of using a com- puter to replace human operators in a known process.” We disagree. We conclude that, when considered as a whole, and in light of the written description, claims 1, 9, and 14 of the ’262 patent are directed to an improved system for Case: 19-1602 Document: 67 Page: 15 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 15 washing jet engines and not to an abstract idea. In our view, the claims are directed to a specific system that im- proves jet engine washing; the claims are not directed to “a result or effect that itself is the abstract idea” of, e.g., auto- mated jet engine washing. In other words, the claims of the ’262 patent do not recite the mere desired result of au- tomated jet engine washing, but rather, recite a specific so- lution for accomplishing that goal. See Koninkljijke Kpn N.V. v. Gemalto M2M GMBH, 942 F.3d 1143, 1151 (Fed. Cir. 2019) (“Importantly, the claims do not simply recite, without more, the mere desired result of catching previ- ously undetectable systematic errors, but rather recite a specific solution for accomplishing that goal—i.e., by vary- ing the way check data is generated by modifying the per- mutation applied to different data blocks.”); see also Core Wireless Licensing S.A.R.L. v. LG Electronics, Inc., 880 F.3d 1356, 1362 (Fed. Cir. 2018) (“Although the generic idea of summarizing information certainly existed prior to the invention, these claims are directed to a particular manner of summarizing and presenting information in electronic devices.”); Finjan, Inc. v. Blue Coat Sys., Inc., 879 F.3d 1299, 1305–06 (Fed. Cir. 2018) (“The asserted claims are . . . directed to a non-abstract improvement in com- puter functionality, rather than the abstract idea of com- puter security writ large”); Thales, 850 F.3d at 1348–49 (“These claims are not merely directed to the abstract idea of using mathematical equations for determining the rela- tive position of a moving object to a moving reference frame, . . . . Rather, the claims are directed to systems and methods that use inertial sensors in a non-conventional manner to reduce errors in measuring the relative position and orientation of a moving object on a moving reference frame.”) (internal quotation marks omitted). The systems of the claims at issue achieve a level of automation that provides an improvement over the prior art human-operated washing systems. This improvement, as set forth in the specification of the ’262 patent, provides Case: 19-1602 Document: 67 Page: 16 Filed: 10/08/2020 16 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES such advantages as “a higher degree of quality of an engine washing procedure,” a “minimize[d] risk of wrongly op- erat[ed] equipment,” “a higher degree of safety,” and “cost efficien[cy] and reliab[ility].” ’262 patent col. 4 ll. 12–14, 42–46, 47–49. These described advantages are important to our determination that the claims provide a technical improvement to jet engine washing, much as the ad- vantages gained by the elements recited in the claimed de- vice in Cardionet were considered to be important to the determination that the claims there were drawn to an im- proved cardiac monitoring device, not an abstract idea. 955 F.3d at 1368. In reaching this conclusion in Cardionet, we noted that the claimed device “more accurately detects the occurrence of atrial fibrillation and atrial flutter” and “al- lows for more reliable and immediate treatment of these two medical conditions.” Id. at 1368–69. Contrary to CAS’s arguments, the fact that the claims require an “information unit” that can be a computer and that, therefore, the system provides an improvement over human-operated engine washing does not necessarily mean the claims are directed to an abstract idea. Indeed, we addressed whether “claims simply use a computer as a tool to automate conventional activity” in the context of Al- ice step one in McRO. 837 F.3d at 1314. In McRO, the representative claim was directed to “[a] method for auto- matically animating lip synchronization” that used “rules” to perform animation. We held that the claim was not di- rected to an abstract idea. Id. at 1316. In reaching that conclusion, we noted that the claim did not use a computer as a tool to automate conventional activity and instead em- ployed a computer “to perform a distinct process to auto- mate a task previously performed by humans.” Id. at 1314. Here, as the specification makes clear, human operators were washing aircraft engines before the patented inven- tion. That the claimed system achieves automation of a task previously performed by humans, however, does not mean the claimed system is necessarily directed to an Case: 19-1602 Document: 67 Page: 17 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 17 abstract idea. The claims of the ’262 patent are directed to a specific combination of a type of washing unit, infor- mation detector, and control unit, configured in a certain way to create technical improvements to systems for wash- ing jet engines. In our view, the claims of the ’262 patent thus present an even stronger case for eligibility than the representative method claim in McRO. 5 5 We recognize that “the mere recitation of a generic computer cannot transform a patent-ineligible abstract idea into a patent-eligible invention.” Alice, 573 U.S. at 223. In cases from our court addressing the eligibility of claims directed to various ways to manipulate data using a computer, we have similarly stated that an underlying ab- stract idea cannot be “saved” from its abstractness through either (1) the use of the computer as a tool or (2) another component that merely provides a generic environment in which to carry out the abstract idea. Customedia Techs. v. Dish Network Corp., 951 F.3d 1359, 1364–65 (Fed. Cir. 2020) (“[I]t is not enough, however, to merely improve a fundamental practice or abstract process by invoking a computer merely as a tool. . . [T]he claimed invention is at most an improvement to the abstract concept of targeted advertising wherein a computer is merely used as a tool.”); BSG Tech LLC v. Buyseasons, Inc., 899 F.3d 1281, 1286– 87 (Fed. Cir. 2018) (holding that the claims at issue were directed to the abstract idea of considering historical usage information while inputting data and that the claims’ reci- tation of a specific database structure merely “provides a generic environment in which the claimed method is per- formed” and “does not save the asserted claims at [Alice] step one.”); see also Bozeman Fin. v. Fed. Reserve Bank of Atlanta, 955 F.3d 971, 979–80 (Fed. Cir. 2020) (holding the claims at issue to be “directed to the abstract idea of col- lecting and analyzing information for financial transaction Case: 19-1602 Document: 67 Page: 18 Filed: 10/08/2020 18 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES fraud or error detection,” and stating that “the use of well- known computer components to collect, analyze, and pre- sent data, in this case to verify financial transactions, does not render these claims any less abstract.”); Credit Ac- ceptance Corp. v. WestLake Servs., 859 F.3d 1044, 1055 (Fed. Cir. 2017) (rejecting as patent ineligible claims where the ‘‘focus . . . [was] on [a] method of financing, and [where] the recited generic computer elements [were] invoked merely as a tool”) (internal quotation marks and citation omitted); Fairwarning IP, LLC v. Iatric Sys., Inc., 839 F.3d 1089, 1093–94 (Fed. Cir. 2016) (holding that claims “di- rected to collecting and analyzing information to detect misuse and notifying a user when misuse is detected” were “directed to a combination of . . . abstract-idea categories” despite the claims’ recitation of a computer); In re TLI Commc’ns LLC Patent Litig., 823 F.3d 607, 611 (Fed. Cir. 2016) (“While [representative] claim 17 requires concrete tangible components such as ‘a telephone unit’ and a ‘server,’ the specification makes clear that the recited phys- ical components merely provide a generic environment in which to carry out the abstract idea of classifying and stor- ing digital images in an organized manner.”); Content Ex- traction & Trans. v. Wells Fargo Bank, 776 F.3d 1343, 1347 (Fed. Cir. 2014) (holding that although the claims at issue recited a scanner in addition to a computer, the claims were “drawn to the abstract idea of 1) collecting data, 2) recog- nizing certain data within the collected data set, and 3) storing that recognized data in a memory”); Intellectual Ventures I LLC v. Erie Indem. Co., 711 Fed. Appx. 1012, 1015 (Fed. Cir. 2017) (concluding that claims directed to a “computer-implemented method” “are directed to the iden- tification of unwanted files in a particular field (i.e., a com- puter network) and otherwise concern data collection related to such identification, such that they are directed to an abstract idea under our precedent”). Case: 19-1602 Document: 67 Page: 19 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 19 The precedential cases from this court upon which CAS relies: OIP Technologies, Intellectual Ventures I, and Ban- corp, all address the use of a computer in the context of analysis under Alice step two, not in the context of analysis under Alice step one. Specifically, in OIP Technologies, we stated that “relying on a computer to perform routine tasks more quickly or more accurately is insufficient to render a patent claim eligible.” This, however, was after we had de- termined the claims at issue were “directed to” the abstract idea of a fundamental economic concept. 788 F.3d at 1363. Likewise, in Intellectual Ventures I, we stated “our prece- dent is clear that merely adding computer functionality to increase the speed or efficiency of the process does not con- fer patent eligibility on an otherwise abstract idea.” 792 F.3d at 1370. That sentence, however, was preceded by a sentence stating: “Turning to the second step of Alice, here there is no inventive concept that would support patent el- igibility.” Id.; see also id. at 1367 (“Nor, in addressing the second step of Alice, does claiming the improved speed or efficiency inherent with applying the abstract idea on a computer provide a sufficient inventive concept.”). Finally, in Bancorp, while we stated that “the fact that [the re- quired calculations] could be performed more efficiently via a computer does not materially alter the patent eligibility Unlike the claims in these cases, the claims of the ’262 patent are not directed to various ways to manipulate data using a computer. Rather, they are directed to a specific system that improves jet engine washing. Just as the in- clusion of a computer cannot “save” an abstract idea, it can- not convert a non-abstract idea into an abstract one. Diamond v. Diehr, 450 U.S. 173, 187 (1981) (“A claim drawn to subject matter otherwise statutory does not be- come non-statutory simply because it uses a mathematical formula, computer program, or digital computer.”); see also Alice, 573 U.S. at 223 (discussing Diehr in the context of step two). Case: 19-1602 Document: 67 Page: 20 Filed: 10/08/2020 20 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES of the claimed subject matter,” that statement was made after we had concluded that the patent was directed to the abstract idea of managing a stable value protected life in- surance policy. 687 F.3d at 1278 (applying Bilski v. Kap- pos, 561 U.S. 593 (2010)). As noted, CAS contends we should narrow our focus to the “automation” of the claims under Chargepoint and Chamberlain. In Chargepoint, we held that the claims at issue were directed to the abstract idea of communicating over a network. 920 F.3d at 770. We determined that, de- spite the recitation of tangible features pertaining to vehi- cle charging stations, the “focus” of the claims “was on the abstract idea of network communication for device interac- tion.” Id. In reaching this conclusion, we found it “no- tabl[e]” that “the specification never suggest[ed] that the charging station itself is improved from a technical per- spective, or that it would operate differently than it other- wise could.” Id. at 768. Similarly, in Chamberlain, we found claims reciting a “movable barrier operator” to be di- rected to wirelessly communicating status information about a system because “[t]he only described difference be- tween the prior art movable barrier operator systems and the claimed . . . system is that the status information about the system is communicated wirelessly, in order to over- come certain undesirable disadvantages of systems using physical signal paths.” 935 F.3d at 1346. Significantly, there was no dispute in Chamberlain that wireless commu- nication was previously well known and we noted its simi- larity to ideas previously found to be abstract. Id. at 1345, 1346. The facts here are different from those of Chargepoint and Chamberlain. Here, as discussed above, we do not have the situation where there was a pre-existing system being used to which only a known feature, similar to fea- tures previously determined to be abstract, was added. In- stead, here, the system itself is new. See Research Corp. Techs. v. Microsoft Corp., 627 F.3d 859, 869 (Fed. Cir. 2010) Case: 19-1602 Document: 67 Page: 21 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 21 (“[I]nventions with specific applications or improvements to technologies in the marketplace are not likely to be so abstract that they override the statutory language and framework of the Patent Act.”). Moreover, as we have pre- viously stated, automation alone is not necessarily ab- stract. McRO, 837 F.3d at 1313. Specifically, as we have stated, “processes that automate tasks that humans are ca- pable of performing are patent eligible if properly claimed.” Id. The system claims at issue provide examples of such proper claiming. In sum, when we consider the claims at issue “in their entirety,” we conclude that “their character as a whole” is not directed to an abstract idea. McRO, 837 F.3d at 1312 (citing Internet Patents Corp. v. Active Network, Inc., 790 F.3d 1343, 1346 (Fed. Cir. 2015)). To conclude otherwise would be to oversimply the claims, which we have cau- tioned against. See McRO, 837 F.3d at 1313. Having so concluded, we need not reach Alice step two and the argu- ments the parties make with respect thereto. See id. at 1316. We turn next to the issues of claim construction and infringement of claims 1, 9, and 14 of the ’262 patent. III. A. Claim terms are given their ordinary and customary meaning, as would be understood by a person of ordinary skill in the art at the time of invention in light of the claim language, the specification, and prosecution history. Phil- lips v. AWH Corp., 415 F.3d 1303, 1312–17 (Fed. Cir. 2005). “A claim term should be given its ordinary meaning in the pertinent context, unless the patentee has made clear its adoption of a different definition or otherwise disclaimed that meaning.” Ancora Techs., Inc. v. Apple, Inc., 744 F.3d 732, 734 (Fed. Cir. 2014). When a patentee “unequivocally and unambiguously disavows a certain meaning to obtain Case: 19-1602 Document: 67 Page: 22 Filed: 10/08/2020 22 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES a patent, the doctrine of prosecution history disclaimer nar- rows the meaning of the claim consistent with the scope of the claim surrendered.” Biogen Idec, Inc. v. Glax- oSmithKline LLC, 713 F.3d 1090, 1095 (Fed. Cir. 2013) (cit- ing Omega Eng’g, Inc. v. Raytek Corp., 334 F.3d 1314, 1323, 1326 (Fed. Cir. 2003)). B. On appeal, CAS maintains its argument that the dis- trict court’s claim construction was erroneous because it did not require the “information detector” to read from an “information unit.” CAS argues that the ’262 patent speci- fication exclusively discloses an information detector that reads an information unit such as an RFID chip or a bar code label. Appellant’s Br. 18–20 (citing ’262 patent col. 5 ll. 32–35, 38–61, col. 6 ll. 35–43). An amendment made during prosecution supports its claim construction, CAS contends. This is so because an earlier version of claim 1 recited detecting the engine type using an “information node.” The patent examiner rejected the “node” language as lacking written description, and pointed out that the ap- plication used the term “detector,” which is “a device or in- strument designed to detect the presence of something, [whereas] a node is a central or connecting point.” J.A. 160–61. CAS urges that when the applicant amended the claim to recite “information detector,” the applicant disa- vowed a broader claim scope for components that do not “detect the presence of something” (i.e., an information unit). Even if not rising to the level of a disavowal, CAS argues, the amendment reinforces the proposition that an information detector must detect an information unit. Un- der a proper construction of the term, CAS asserts, the ac- cused devices do not infringe because EcoServices did not argue or present evidence that Cyclean® includes an “in- formation detector” that requires reading an information unit. Instead, the keypad of the Cyclean® devices is a man- ual entry device, CAS states. Case: 19-1602 Document: 67 Page: 23 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 23 EcoServices responds that the district court properly refused to import the term “information unit” into the as- serted claims. EcoServices argues that other claims of the ’262 patent that are not at issue in this case require an “in- formation unit,” thereby confirming that CAS’s construc- tion is incorrect under the principle of claim differentiation. Appellee’s Br. 20–21. Responding to CAS’s argument di- rected to the specification, EcoServices argues that the em- bodiment CAS relies on is merely exemplary. Id. at 21–23. And as to prosecution history, EcoServices responds by not- ing that the amendment adding “information detector” was in the context of a written description rejection, and that the examiner did not reference the “information unit” in making his rejection. Id. at 23–25. C. We agree with EcoServices that the district court’s claim construction was proper. Beginning with the claims, nothing in the language of claim 1, 9, or 14 of the ’262 patent indicates or implies that the “information detector” should be required to read an “information unit.” Further, unasserted claim 6, which ul- timately depends from claim 1, recites that the “infor- mation detector comprises an information detector for reading information provided by [an] information unit, and for providing said information to the control unit.” ’262 pa- tent col. 9 ll. 1–4. Thus, to construe “information detector” as CAS would have us do would “render the term redun- dant and offend[ ] principles of claim differentiation.” Tre- bro Mfg. Inc. v. Firefly Equip., LLC, 748 F.3d 1159, 1167 (Fed. Cir. 2014) (holding that the district court erred in con- struing a term in an independent claim to include a re- quirement recited in a dependent claim that also recited other features). Although certain statements in the specification do suggest that an “information detector” is used when an “in- formation unit” is used, see ’262 patent col. 5 ll. 55–61, col. Case: 19-1602 Document: 67 Page: 24 Filed: 10/08/2020 24 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 6 ll. 35–43, the disclosure of a single, exemplary embodi- ment does not necessarily limit the claimed invention to that embodiment. Continental Circuits LLC v. Intel Corp., 915 F.3d 788, 797 (Fed. Cir. 2019) (“[D]isclosing only the ProbelecXB 7081 embodiment, without more, does not re- sult in a clear disavowal of claim scope.”). Further, the specification does not go so far as to suggest that an infor- mation detector could not be used without an information unit. See ’262 patent col 5 ll. 24–61. We thus do not have the situation where the “preferred embodiment is de- scribed as the invention itself,” such that “the claims are not entitled to a broader scope than that entitlement.” SciMed Life Systems, Inc. v. Advanced Cardiovascular Sys- tems, Inc. 242 F.3d 1337, 1341 (Fed. Cir. 2001) (concluding that the patentee disclaimed a dual lumen configuration for balloon dilation catheters where the patent described both a dual lumen (side-by-side) and coaxial lumen config- uration, but the specification disparaged the dual lumen design, described the coaxial lumen design as “the present invention,” and explained that the coaxial lumen design was the structure “for all embodiments of the present in- vention contemplated and disclosed herein”). We also disagree with CAS that the amendment the applicant made during prosecution of the ’262 patent sup- ports CAS’s construction. The examiner defined a “detec- tor” to be “a device or instrument designed to detect the presence of something.” J.A. 161. He did not go so far, however, as to require that the information detector read from “an information unit.” The amendments made thus cannot be said to constitute an unequivocal and unambig- uous disavowal of a device that does not read from “an in- formation unit.” See Biogen, 713 F.3d at 1095. Accordingly, the district court did not err when it con- strued the claim term “information detector.” CAS’s non- infringement position depends on its argument that the court’s claim construction was incorrect. Accordingly, we affirm the court’s denial of CAS’s motions for renewed Case: 19-1602 Document: 67 Page: 25 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 25 judgment as a matter of law or a new trial as to infringe- ment of claims 1, 9, and 14 of the ’262 patent. We next address CAS’s challenge to the validity of claims 1, 9, and 14 of the ’262 patent under 35 U.S.C. § 103. IV. A. A patent claim is unpatentable when “the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.” 35 U.S.C. § 103(a). 6 Obviousness is a question of law based on underlying findings of fact. In re Gartside, 203 F.3d 1305, 1316 (Fed. Cir. 2000). The under- lying factual findings include (1) “the scope and content of the prior art,” (2) “differences between the prior art and the claims at issue,” (3) “the level of ordinary skill in the perti- nent art,” and (4) the presence of secondary considerations of nonobviousness such as, e.g., “commercial success, long felt but unsolved needs, [and] failure of others.” Graham v. John Deere Co. of Kan. City, 383 U.S. 1, 17 (1966). B. CAS contends that the district court erred when it sub- mitted to the jury, without proper instruction, the issue of obviousness. Specifically, CAS takes issue with the court’s 6 Congress amended § 103 when it passed the Leahy- Smith America Invents Act (“AIA”). Pub. L. No. 112-29, § 3(c), 125 Stat. 284, 287 (2011). However, because the ap- plication that resulted in the ’262 patent was filed before March 16, 2013, the pre-AIA version of § 103(a) applies. See id. § 3(n)(1), 125 Stat. at 293; Redline Detection, LLC. v. Star Envirotech, Inc., 811 F.3d 435, 449 n.7 (Fed. Cir. 2015). Case: 19-1602 Document: 67 Page: 26 Filed: 10/08/2020 26 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES inference in the Post-Judgment Order that the jury had found no motivation to combine Leusden’s engine washing system and Hansen’s RFID technology (“information detec- tor”), given that the jury was not provided an instruction regarding motivation to combine. Further, CAS argues that a finding of no motivation to combine would not be supported by substantial evidence or would be at least against the great weight of the evidence, since CAS pro- vided evidence of the “reason” to combine the references via its expert’s testimony on increased automation. EcoServices responds that the jury instructions listed the Graham factors and contends that this encompasses motivation to combine. C. Patent claims are presumed valid. 35 U.S.C. § 282. “At trial, the party challenging validity must prove that the claims are invalid by clear and convincing evidence.” Po- lara Eng’g Inc. v. Campbell Co., 894 F3d 1339, 1348 (Fed. Cir. 2018) (citation omitted). Although there was no specific jury instruction di- rected to motivation to combine, the jury was directed to consider: (1) “the scope and content of the prior art relied upon by CAS,” (2) “the difference or differences, if any, be- tween each Asserted Claim that CAS contends is obvious and the prior art,” (3) “the level of ordinary skill in the art at the time the inventions of the asserted patents were made,” and (4) “additional considerations, if any, that indi- cate that the invention was obvious or not obvious.” J.A. 655. The first three of these factors track the first three factors set forth in Graham. The fourth jury factor the jury was to consider, “additional considerations, if any, that in- dicate that the invention was obvious or not obvious” is no- ticeably broader than the secondary considerations of nonobviousness set forth in Graham, and encompasses the motivation to combine evidence put forth by both parties during trial. The jury was entitled to credit EcoServices’ Case: 19-1602 Document: 67 Page: 27 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 27 expert’s testimony over the limited testimony it heard from CAS’s expert. Moreover, CAS does not argue before us, nor did it argue before the district court, that the jury instruc- tion was legally erroneous. Viewed in the light most favor- able to EcoServices, the evidence does not permit only one reasonable conclusion that is contrary to the jury’s verdict. See Josephs, 443 F.3d at 1062. This is particularly the case since, as the patent challenger, CAS needed to establish obviousness by clear and convincing evidence. Accordingly, it was not error for the district court to deny judgment as a matter of law, nor was it an abuse of discretion for the court to deny a new trial on invalidity. We now turn to the ’860 patent. V. A. A patent must “conclude with one or more claims par- ticularly pointing out and distinctly claiming the subject matter which the applicant regards as the invention.” 35 U.S.C. § 112(b). 7 “A claim fails to satisfy this statutory re- quirement and is thus invalid for indefiniteness if its lan- guage, when read in light of the specification and the prosecution history, ‘fail[s] to inform, with reasonable cer- tainty, those skilled in the art about the scope of the inven- tion.’” Interval Licensing LLC v. AOL, Inc., 766 F.3d 1364, 1369–70 (Fed. Cir. 2014) (quoting Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898, 901 (2014)). To meet this standard, claims including a term of degree “must provide 7 Like § 103, § 112 was amended when Congress passed the AIA. Pub. L. No. 112-29, § 4(c), 125 Stat. at 296–97. However, because the application that resulted in the ’860 patent was filed before September 16, 2012, the pre-AIA version of § 112 applies. See id. § 4(e), 125 Stat. at 297; Knowles Elecs. LLC v. Cirrus Logic, Inc., 883 F.3d 1358, 1365 (Fed. Cir. 2018). Case: 19-1602 Document: 67 Page: 28 Filed: 10/08/2020 28 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES objective boundaries for those of skill in the art.” Id. at 1370–71. B. CAS contends that the claims of the ’860 patent are ei- ther indefinite or are not infringed. CAS maintains its ar- gument that the claim term “at a liquid particle size in the range of 250–120μm” is indefinite because a skilled artisan would not know with reasonable certainty what it means for a washing liquid to be sprayed “at a liquid particle size in the range of 250–120μm.” Nothing in the intrinsic rec- ord, CAS agues, informs an artisan what percentage of a spray’s particles must be within the recited range to achieve the claimed objective of being “finely-divided to a degree at which the particles of liquid will follow the same routes through the turbine compressor as those previously taken by the air-borne contaminants” or to achieve the ob- jectives set forth in the specification of “overcoming the centrifugal effect,” washing “effectively with far less quan- tities of liquid,” and reducing strain on the engine. Appel- lant’s Br. 48–54 (quoting ’860 patent col. 4 ll. 12–15, col. 1 ll. 28–50, col. 2 ll. 14–18). If the claims do provide such an objective boundary and are therefore definite, CAS con- tends, then substantial evidence does not support the in- fringement verdict because the trial record does not identify that objective boundary. Rather, CAS argues, the infringement verdict relies upon the theory that only one particle must fall within the claimed range. Id. at 54–56. EcoServices responds that claim 1 is definite because it “specifies a series of parameters and the result that follow- ing those parameters achieves, . . . i.e., ‘the liquid particles are given a size and velocity which together overcome the centrifugal effect,’ so that ‘all accessible surfaces of the ob- ject will be cleaned effectively and efficiently.’” Appellee’s Br. 49–50 (quoting ’860 patent col. 4 ll. 4–15 & col. 2 ll. 15– 18). According to EcoServices, “[t]he evidence that a par- ticular spray within the defined parameters achieves the Case: 19-1602 Document: 67 Page: 29 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 29 objectives of the invention—i.e., that droplets follow the gas path—is the same evidence that enables a skilled arti- san to determine whether an accused product infringes.” Id. at 50. According to EcoServices, testing performed by its expert showed that 10–35% of liquid particles produced by the nozzles were within the claimed range. Id. at 52– 55. EcoServices also asserts that CAS’s own documenta- tion shows the functional limitations of the claim were met. Id. at 48, 53. This constitutes substantial evidence to sus- tain the jury’s infringement verdict, EcoServices urges. EcoServices disputes that it argued that having one parti- cle in the range would infringe. Rather, so long as “small quantities” are sprayed through the compressor within the claimed parameters and “thereby” follow the gas path through the compressor, it doesn’t matter if other quanti- ties also follow that path. Id. at 50. C. We agree with EcoServices that the claim term at issue relating to particle size is not indefinite. As EcoServices argues, claim 1 of the ’860 patent requires more than just “at a liquid particle size in the range of 250–120µm.” In- stead, the claim recites: A method of washing turbine compressors . . . wherein small quantities of finely-divided liquid are sprayed onto and through the turbine compres- sors, characterized by running the turbine com- pressors and spraying the finely-divided liquid quantities through at least one nozzle towards and through the turbine compressor . . . at a liquid par- ticle size in the range of 250–120µm . . . whereby the liquid is finely-divided to a degree at which the particles of liquid will follow the same routes through the turbine compressor as those previously taken by the air-borne contaminants, when spray- ing said liquid onto and through said turbine com- pressor. Case: 19-1602 Document: 67 Page: 30 Filed: 10/08/2020 30 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES ’860 patent col. 3 l. 17–col. 4 l. 16. As such, although the claim does not state a percentage of the liquid that must be in the claimed particle size, the claim makes clear that “small quantities” of liquid must follow the gas path. Whether a single particle would meet this claim limitation is not at issue: CAS presented undisputed evidence show- ing that 10–35% of its spray did meet the claim limitation. EcoServices’ testing evidence, combined with CAS’s documentation indicating that, e.g., Cyclean® utilizes “an evenly distributed water mist [that] follows the gas path,” see J.A. 1268–69; J.A. 2575, is substantial evidence that supports the jury’s verdict. That the remaining spray was not in the claimed particle size range does not mean the claim element was not met; nothing in the claim requires the “small quantities of finely-divided liquid” sprayed into the turbine compressor be the only liquid particles used. In other words, the fact that the accused Cyclean® Engine Wash system uses particles of different sizes in addition to those within the claimed range does not mean the claim was not infringed by the 10–35% of the spray that does sat- isfy the claim element. See Broadcom Corp. v. Emulex Corp., 732 F.3d 1325, 1333 (Fed. Cir. 2013) (“It is well set- tled that an accused device that sometimes, but not always, embodies a claim[ ] nonetheless infringes.”) (internal quo- tation marks and citation omitted). The claim term “at a liquid particle size in the range of 250–120µm” is not indefinite and substantial evidence sup- ports the jury’s verdict. Accordingly, we affirm the district court’s denial of judgment as a matter of law or a new trial as to infringement of the ’860 patent. We turn now to the issue of supplemental damages and an ongoing royalty. VI. A. Supplemental damages compensate the patentee for periods of infringement not considered by the jury. Dow Case: 19-1602 Document: 67 Page: 31 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 31 Chem. Co. v. Nova Chemicals Corp., (Canada), 803 F.3d 620, 626 (Fed. Cir. 2015) (citation omitted). In the absence of a permanent injunction, a patentee may be entitled to receive ongoing royalties. Paice LLC v. Toyota Motor Corp., 504 F.3d 1293, 1314 (Fed. Cir. 2007). B. CAS’s final argument on appeal is that the district court abused its discretion when it awarded EcoServices supplemental damages in the amount of $175,000 and an ongoing royalty at a rate of $400 per wash. Appellant’s Br. 56–61. CAS contends that the $400 per wash rate for sup- plemental damages and for the ongoing royalty was based almost exclusively on the value of the ’860 patent, and be- cause it has expired, it cannot be a basis for a royalty under Kimble v. Marvel Entertainment, LLC, 576 U.S. 446 (2015). According to CAS, EcoServices’ expert calculated the rea- sonable royalty based on a hypothetical negotiation in 2010, when the ’262 patent had not yet issued. Id. at 57. In response, EcoServices contends that CAS misreads Kimble. Appellee’s Br. 55–56. EcoServices points out that, in Kimble, the Supreme Court stated that “royalties may run until the latest-running patent covered in the parties’ agreement expired.” Id. (quoting 576 U.S. at 454) (empha- sis added). EcoServices then posits that since the ’262 pa- tent has not expired, the royalty rate set by the district court is proper. EcoServices also contends that (a) despite the time frame of its expert’s hypothetical negotiation, the hypothetical negotiation was based on both patents, and (b) the jury was aware of the expiration of the ’860 patent, and yet still awarded the equivalent of $400 per wash in its $1,949,600 damages award. Id. at 56–57, 59–60. In addi- tion, EcoServices points to its expert’s reliance on two agreements: (1) the LHT-CAS Lease Agreement under which CAS agreed to pay Luthansa a $550 royalty per Cy- clean® wash it performed; and (2) a license agreement that granted EcoServices rights to a portfolio that included the Case: 19-1602 Document: 67 Page: 32 Filed: 10/08/2020 32 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES ’860 and ’262 patents, and which corresponded to an aver- age royalty of $450 per wash that EcoServices was expected to pay. Id. at 57–59. C. We agree with CAS. EcoServices’ expert’s generalized statement that his “royalty considers the economic life of both of [the] patents,” J.A. 1415, does not mean that he af- forded the ’262 patent any value. Instead, EcoServices’ ex- pert specifically stated that he did not perform a royalty valuation for the ’262 patent alone because the ’860 patent would have been the “driver of the negotiation in 2010.” J.A. 1402–03. Indeed, EcoServices’ expert repeatedly stated the significance of the ’860 patent. See J.A. 1338– 39 (emphasizing that in patent portfolios, often “a few pa- tents . . . carry the majority of the value[, a]nd in this case insofar as these engine washing systems are concerned, the ’860 is very, very important”); J.A. 1398 (“[T]he ’860 is ob- viously a very important patent . . . .”), J.A. 1405 (“The ’860 is a really important patent . . . .”). EcoServices’ expert val- ued the ’860 patent alone at $500 per wash, but also noted that the patent expired approximately 77% of the way through the damages period. J.A. 1401. Accordingly, he “accounted for the loss in the value of the ’860 patent by reducing [his] royalty.” Id. In the view of EcoServices’ ex- pert, looking purely at the infringement period before the ’860 patent expired and multiplying washes during that pe- riod by the estimated value of $500 per wash, “you end up with a damages number that’s very similar” to the damages calculated by multiplying $400 per wash times the total number of washes performed in the infringement period. 8 8 The jury’s award of $1,949,600 is equivalent to a $400 per wash rate for the number of washes that occurred in the total infringement period. J.A. 675, 1402, 1408. Multiplying $500 per wash times the number of washes Case: 19-1602 Document: 67 Page: 33 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 33 This testimony shows that EcoServices’ expert awarded lit- tle, if any, value to the ’262 patent. In Kimble, the Supreme Court held that the expiration of a licensed patent does not mean that negotiated provi- sions in a settlement agreement licensing that patent nec- essarily cease to be effective. 576 U.S. 453–54, 464. Rather, such an arrangement can accomplish payment de- ferral and risk-spreading. Id. This does not mean, how- ever, that a patent holder therefore has a right to exact royalties for sales occurring after a patent’s expiration date outside the context of such an agreement. Indeed, the Kim- ble Court itself acknowledged the opposite. Id. at 451 (“[W]hen the patent expires, the patentee’s prerogatives ex- pire too, and the right to make or use the article, free from all restriction, passes to the public.”). In Kimble, the court addressed a settlement agreement the parties inde- pendently entered into, not a post-infringement, court-im- posed, forward-looking royalty. Id. at 450. We do not see how Kimble applies to this case. One purpose of an ongoing royalty is to “effectively serve[ ] as a replacement for whatever reasonable royalty a later jury would have calculated in a suit to compensate the patentee for future infringement.” XY, 890 F.3d at 1297 (citation omitted). Here, the record does not support that a later jury would have calculated a royalty of $400 per wash as a royalty award for infringement of the ’262 patent alone. The district court abused its discretion by awarding supplemental damages and an ongoing royalty based upon the jury’s per-wash damages rate that included compensation for infringement of the now-expired ’860 pa- tent. that occurred in the infringement period before the ’860 pa- tent expired (3,845 washes) would have resulted in dam- ages of $1,922,500. See J.A. 1402. Case: 19-1602 Document: 67 Page: 34 Filed: 10/08/2020 34 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES Accordingly, we vacate and remand for further pro- ceedings regarding supplemental damages and the ongoing royalty rate. CONCLUSION For the foregoing reasons, we hold that claims 1, 9, and 14 of the ’262 patent are eligible for patenting, are not in- valid, and were infringed, and that claims 1 and 2 of the now-expired ’860 patent are not indefinite and were in- fringed. We therefore affirm the judgment of infringement of these claims of the ’262 patent and the ’860 patent. We also hold, however, that the district court abused its discre- tion in awarding supplemental damages and an ongoing royalty based upon a rate of $400 per wash. Accordingly, we vacate the district court’s supplemental damages award and ongoing royalty. The case is remanded to the district court for a redetermination of the proper supplemental damages and ongoing royalty. 9 AFFIRMED-IN-PART, VACATED-IN PART, AND REMANDED COSTS No costs. 9 We have considered the parties’ other arguments, but have found them to be not relevant to our disposition of the appeal.

I join Parts II-A, II-B, V, and VI of the majority opinion, but respectfully dissent from Part II-C of the majority’s de- cision holding that claims 1, 9, and 14 of U.S. Patent No. 9,162,262 (“the ’262 patent”) are patent eligible under 35 U.S.C. § 101. Because those claims are not patent eligible, I would not reach the questions in Parts III and IV regard- ing infringement and invalidity (based on obviousness) of claims 1, 9, and 14. Case: 19-1602 Document: 67 Page: 36 Filed: 10/08/2020 2 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES I Turbine engines consume large quantities of air that cause a coating of foreign particles and contaminants to build up in the engine compressor. This build-up, known as compressor fouling, negatively affects engine perfor- mance. For decades, turbine engines have been washed to remove compressor fouling, and this process was largely automated. Different engine types required different washing parameters. The operator entered variables, such as flow rates and wash times, depending on the type of en- gine being washed. The ’262 patent notes that it would be beneficial for the turbine engine washing process “if the influence of the hu- man factor is minimized as much as possible.” ’262 patent, col. 3 ll. 65–67. To that end, the patent describes a com- puter-directed washing system that further automates the washing process, thereby reducing human error. Id. col. 4 ll. 1–10, 42–46. Under the patented automated process, the operator uses an information detector (such a keypad or a radio-frequency identification reader) to transmit the engine type to the computer, and the computer selects the preferred washing parameters, which do not have to be en- tered manually. Id. col. 6 ll. 34–41, col. 7 ll. 4–11. Inde- pendent claim 1, which is representative, recites: A system for washing turbine engines comprising: a washing unit for providing a washing liq- uid to the turbine engines; an information detector configured to gather information related to engine type; and a control unit configured to accept the in- formation related to engine type from the information detector and to determine a washing program to be used as a function of the information relating to engine type Case: 19-1602 Document: 67 Page: 37 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 3 from a set of preprogrammed washing pro- grams, and further configured to regulate the washing unit according to washing pa- rameters associated with the washing pro- gram used. Id. col. 8 ll. 36–47. 1 What is claimed is the further automation of the wash- ing process using generic computers to select the correct parameters depending on engine type. The majority disa- grees, finding that this claim is patent eligible at step one of the Alice analysis because it is not directed to an abstract idea. The majority states that the claims are “directed to a specific system that improves jet engine washing” and “do not recite the mere desired result of automated jet engine washing.” Maj. Op. 15. But the claims simply describe the generic computer apparatus used to further automate the previous manual process that utilized automated washing systems, as the patentee’s own evidence demonstrates. See ’262 patent, col. 3 ll. 38–43 (describing preexisting “sys- tems for cleaning engines” that “are all dependent to some extent upon an operator manually making certain adjust- ments and/or system settings”); J.A. 1271 (EcoServices’s expert testifying that a “washing unit” is a unit that pro- vides washing liquid); id. at 1274 (EcoServices’s expert tes- tifying that an “information detector” is a keypad pressed 1 Claims 9 and 14 are also at issue in this appeal. Claim 9, which depends from claim 1, recites that the “in- formation provided by the information detector is used by the control unit to regulate a washing time.” ’262 patent, col. 9 ll. 11–13. Independent claim 14 covers a system with similar features recited in claim 1. EcoServices, LLP, the patent owner of the ’262 patent, does not argue that the features in claims 9 and 14 are meaningfully different from claim 1 for § 101 purposes. Case: 19-1602 Document: 67 Page: 38 Filed: 10/08/2020 4 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES by an operator); id. at 411–12 (EcoServices asserting that a “control unit” is a computer). III We look to the claims and specification to determine the focus of the claims and the claimed improvement. See, e.g., ChargePoint, Inc. v. SemaConnect, Inc., 920 F.3d 759, 766–70 (Fed. Cir. 2019), cert. denied, 140 S. Ct. 983 (2020). The claims and the ’262 patent specification make clear that the claimed invention is the further automation of prior art engine manual washing systems. There is no dis- pute that humans entered the established wash parame- ters into automated washing systems, whereas the claimed system computerizes the parameter selection. As the majority recognizes, the specification is “helpful in illuminating what a claim is ‘directed to.’” Maj. Op. 14 (quoting CardioNet, LLC v. InfoBionic, Inc., 955 F.3d 1358, 1368 (Fed. Cir. 2020)); ChargePoint, 920 F.3d at 767 (“The ‘directed to’ inquiry may also involve looking to the specifi- cation to understand ‘the problem facing the inventor’ and, ultimately, what the patent describes as the invention.” (quoting In re TLI Commc’ns LLC Patent Litig., 823 F.3d 607, 612 (Fed. Cir. 2016)). Here, the specification states that prior art washing systems had a problem in that they depended on a human “operator manually making certain adjustments” based on “information regarding the engine type . . . [and] the re- quirements for washing that particular engine type.” ’262 patent, col. 3 ll. 41–55. Manual adjustments were a problem “in particular since many engine washing opera- tions [were] performed during night-time when the opera- tors may not be fully alert.” Id. col.3 ll. 56–64. Upon recognizing the benefits for minimizing “the influence of the human factor” and “the risk of wrongly operating the equipment” by a human, id. col. 3 ll. 65–67, col. 4 ll. 13–14, the specification states that the “present invention pro- vides for a higher degree of safety and quality regarding Case: 19-1602 Document: 67 Page: 39 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 5 wash results obtained in that the washing system is auto- mated,” and “[a]s a result, any human error introduced into the system is greatly reduced,” id. col. 4 ll. 42–46 (emphasis added). Hence, the claimed invention, as evident from the specification, is simply providing an aggregate of instruc- tions determined by engine type when previously, an oper- ator would individually enter the established parameters into the washing system. In addition to the specification, EcoServices’s own evi- dence confirms this. At trial, the inventor of the ’262 pa- tent testified that the claimed invention’s improvement was simply to “completely eliminat[e] subjectivity” of hu- man operators. J.A. 55–56. And during oral argument, EcoServices conceded that the claimed invention “is an au- tomation of something that was previously done by people,” Oral Arg. at 18:40–46, http://oralarguments.cafc.uscourts. gov/default.aspx?fl=19-1602.mp3, and that “manual [hu- man] operators” did the washing operations using “appro- priate parameters” based on the engine type as recited in the claims, id. at 29:30–30:05. As counsel for Ecoservices confirmed, before the ’262 patent, a human operator would consult a card for the type of engine to be washed, and en- ter the established flow parameters for the engine type. 2 2 The Court: Manual operators did that, too, right [i.e., loading “the correct parameters . . . for the correct engine type”]? Mr. Jay: Manual operators selected the engine type. In other words, a manual operator might know the information about what the appropriate parameters for a particular type of engine are, that’s correct, if they had it on a wallet card or something, . . . but they have to take the right card out, and they have to follow the directions. . . . Case: 19-1602 Document: 67 Page: 40 Filed: 10/08/2020 6 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES The patent simply avoids error by computerizing this man- ually initiated process. See also id. at 17:32–40 (EcoServices admitting the fact that the claimed invention “is an automated process” is what makes it different from prior art); id. at 18:45–19:30 (EcoServices arguing it “is the automation [that] solve[d] [the particular problem]” and that its expert testified that the “problem[] relate[d] to hu- man error in th[e washing] field,” i.e., “the fact that aircraft engines [we]re being washed by individuals, often late at night, often in the dark, and that automation . . . dealt with that problem by avoiding human error”). IV In my view, our case law compels the conclusion that claims 1, 9, and 14 of the ’262 patent are patent ineligible. Our cases have held that the mere automation of manual processes using generic computer components is directed to an abstract idea in Alice step one. Contrary to the major- ity, such cases are not limited to addressing Alice step two and explicitly hold that claims that simply add generic computer components to a preexisting manual process are directed toward an abstract concept at Alice step one. See, e.g., BSG Tech LLC v. BuySeasons, Inc., 899 F.3d 1281, 1286 (Fed. Cir. 2018) (claims were directed to an abstract idea because they amounted to a “[computerized] funda- mental, long-prevalent practice or a well-established method of organizing activity”); FairWarning IP, LLC v. Iatric Sys., Inc., 839 F.3d 1089, 1093–94 (Fed. Cir. 2016) (claims “implement[ing] an old practice in a new [com- puter] environment” were “directed to an abstract idea”); In re TLI Commc’ns, 823 F.3d at 612 (explaining that claims “simply adding conventional computer components Humans are not going to do so with the same de- gree of precision. Oral Arg. at 29:05–30:10. Case: 19-1602 Document: 67 Page: 41 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 7 to well-known business practices” and “generalized steps to be performed on a computer using conventional computer activity” are directed to an abstract idea (quoting Enfish, LLC v. Microsoft Corp., 822 F.3d 1327, 1338 (Fed. Cir. 2016) (internal quotation marks omitted)). 3 V The majority’s finding that the claims here are not di- rected to an abstract idea appears to rest primarily on the advantages of further automation, the majority admitting that the “described advantages are important to [its] deter- mination.” Maj. Op. 16. The existence of the advantages resulting from further automation (i.e., “a higher degree of quality of an engine washing procedure,” a “minimize[d] risk of wrongly operat[ed] equipment,” “a higher degree of safety,” and “cost efficien[cy] and reliab[ility],” ’262 patent, col. 4 ll. 12–14, 42–49) do not make the claims patent eligi- ble. Such improvements are exactly the types of improve- ment resulting from computerization of well-known activities that courts have repeatedly held to be insufficient to render claims non-abstract. See, e.g., Customedia 3 See also Bozeman Fin. LLC v. Fed. Reserve Bank of Atlanta, 955 F.3d 971, 979 (Fed. Cir. 2020) (“[T]he use of well-known computer components to . . . verify financial transactions [that were a long-standing commercial prac- tice] d[id] not render the[] claims any less abstract.”); Con- tent Extraction & Transmission LLC v. Wells Fargo Bank, Nat’l Ass’n, 776 F.3d 1343, 1347 (Fed. Cir. 2014) (computer- implemented claims were directed to an abstract idea of “data collection, recognition, and storage” that were well- known); Intellectual Ventures I LLC v. Erie Indem. Co., 711 F. App’x 1012, 1015–16 (Fed. Cir. 2017) (“[C]laims [we]re directed to the [abstract idea of] identification of unwanted files in a particular field (i.e., a computer network)” where they “merely implement an old practice in a new [comput- erized] environment”).

Cir. 2020) (“generic speed and efficiency improve- ments inherent in applying the use of a computer to any task” were not directed to a patent-eligible improvement to computer functionality); BSG Tech, 899 F.3d at 1288 (“ben- efits that flow from performing an abstract idea in conjunc- tion with a well-known database structure” were not patent-eligible); Credit Acceptance Corp. v. Westlake Servs., 859 F.3d 1044, 1055 (Fed. Cir. 2017) (“[M]ere automation of manual processes using generic computers does not con- stitute a patentable improvement in computer technol- ogy.”). The majority attempts to distinguish these cases as “addressing the eligibility of claims directed to various ways to manipulate data using a computer.” Maj. Op. 17– 19 n.5. These cases are not so limited. See Bozeman, 955 F.3d at 979 (rejecting the argument that if a “process in- volves tangible steps, it cannot be an abstract idea, even if the claims additionally involve or include otherwise ab- stract concepts”). But even under the majority’s interpretation, these cases control here. EcoServices itself concedes that these claims are directed to manipulating data using a computer, stating in its response brief, [T]he claims-in-suit are directed to implementation of the information detector configured to gather in- formation related to the type of engine being washed in combination with the control unit that is configured to utilize that information to regulate the claimed washing unit . . . . Resp. Br. 28 (internal quotation marks omitted). In FairWarning, we held similar claims to be directed toward an abstract idea: The patented method . . . collects information re- garding accesses of a patient’s personal health Case: 19-1602 Document: 67 Page: 43 Filed: 10/08/2020 ECOSERVICES, LLC v. CERTIFIED AVIATION SERVICES 9 information, analyzes the information according to one of several rules . . . to determine if the activity indicates improper access, and provides notifica- tion if it determines that improper access has oc- curred. 839 F.3d at 1093. To be sure, there are patent claims that are eligible be- cause they involve claims that accomplish improvements in a manual process. But here, the claimed invention does not involve “a specific improvement to computer function- ality” that would make the claims directed to a non-ab- stract idea. In re TLI Commc’ns, 823 F.3d at 612. EcoServices itself makes no serious contention that the claims recite improved computer capabilities. The major- ity opinion reaches no such conclusion. There is no basis to conclude that this case involves an improvement in com- puter functionality in contrast to cases such as Koninkljijke Kpn N.V. v. Gemalto M2M GMBH, 942 F.3d 1143 (Fed. Cir. 2019), and Ancora Technologies, Inc. v. HTC America, Inc., 908 F.3d 1343 (Fed. Cir. 2018), as amended (Nov. 20, 2018). 4 4 The majority cites CardioNet, which involved claims for “a device for detecting and reporting the pres- ence of atrial fibrillation or atrial flutter in a patient.” 955 F.3d at 1364. The parties’ focus was almost entirely on whether the existing record showed the claimed process was a longstanding practice. The panel found that the de- fendant did not establish that “doctors long used the claimed diagnostic processes” and that “[n]othing in the record . . . suggest[ed] that the claims merely computer- ize[d] pre-existing techniques.” Id. at 1370. The panel also found that the claimed invention “achieve[d] multiple tech- nological improvements,” such as “more accurately Case: 19-1602 Document: 67 Page: 44 Filed: 10/08/2020 10 ECOSERVICES, LLC v.

In contrast, the claims here do not “focus on a specific means or method that improves the relevant technology.” Id. at 1314. There is no claim here to an improvement to the selec- tion of washing parameters or to the parameters them- selves, to the elimination of human subjectivity, or to an improvement of the washing process other than having a computer enter the established washing parameters in- stead of a human. See, e.g., ’262 patent, col. 8, ll. 36–47; Oral Arg. at 29:38–30:10. EcoServices itself concedes that the improvement here is only “automation” of parameter selection.

CERTIFIED AVIATION SERVICES 11 VI The district court (and the majority) did not reach Alice step two because they determined that claims are not di- rected to an abstract idea in step one. At step two, we search for an “inventive concept.” Alice Corp. v. CLS Bank Int’l, 573 U.S. 208, 217, (2014) (quoting Mayo Collaborative Servs. v. Prometheus Labs., Inc., 566 U.S. 66, 72–73, (2012)). As noted earlier, EcoServices’s own evidence shows that the claimed elements are generic and conven- tional. We have repeatedly held that “generic computer el- ements . . . do not alone transform an otherwise abstract idea into patent eligible subject matter.” FairWarning, 839 F.3d at 1096. EcoServices argues that the combination of the claimed “washing unit,” “information detector,” and “control unit” is an “inventive combination.” Appellee Br. 35. That “in- ventive combination” is simply the abstract idea of further automating the washing process. We have held that “[i]f a claim’s only ‘inventive concept’ is the application of an ab- stract idea using conventional and well-understood tech- niques, the claim has not been transformed into a patent- eligible application of an abstract idea.” BSG Tech, 899 F.3d at 1290–91. “It is well-settled that placing an abstract idea in the context of a computer does not ‘improve’ the computer or convert the idea into a patent-eligible applica- tion of that idea.” Interval Licensing LLC v. AOL, Inc., 896 F.3d 1335, 1346 (citing Alice, 573 U.S. at 223.) That is the case here.
