MarcTec, LLC appeals the summary judgment of the United States District Court for the Southern District of Illinois, holding that U.S. Patents 7,128,753 (“the ’753 patent”) and 7,217,290 (“the ’290 patent”) are not infringed by the Cypher® stent of Johnson & Johnson and Cordis Corporation. The decision turned on the district court’s construction of the term “bonded” in the asserted claims of both patents. We affirm this aspect of the district court’s claim construction, and the judgment of non-infringement based on that construction. 1 DISCUSSION The ’753 and ’290 patents have identical specifications and are directed to a surgical implant in which a polymeric material is bonded by heat to an expandable implant, where the polymer includes a therapeutic agent such as an antibi- otic. Claim 1 is the broadest claim of the ’753 patent: 1. A surgical device for implantation in a body com- prising: an implant, at least a portion of which is expandable; and a polymeric material bonded to the implant, wherein the polymeric material is a ther- moplastic, includes a therapeutic agent, is non- 1 MarcTec, LLC v.

For the ’290 patent, claim 1 is the broadest claim: 1. An implant for implantation in a human body comprising: a tubular member having a channel and mechanically expandable upon activation of a deliv- ery mechanism from a contracted condition in which the tubular member has a first cross sectional size in a plane perpendicular to a longitudinal central axis of the tubular member to an expanded condi- tion in which at least a portion of the tubular mem- ber has a second cross sectional size in a plane perpendicular to the longitudinal central axis of the tubular member, the second cross sectional size be- ing larger than the first cross sectional size to thereby lock the tubular member against tissue in the human body; and a first component bonded to at least a portion of the tubular member and formed of a heat bondable material that includes a therapeu- tic agent selected from the group consisting of a tis- sue ingrowth promoter and an antibiotic, wherein the heat bondable material is non-flowable and non- adherent at room temperature and becomes flow- able, tacky, and adherent upon the application of heat. (Emphases added.) The claims of both patents all include the requirement of a polymeric material or heat bondable material bonded to an implant. Relying on the specification and the Applicants’ arguments during prosecution, the district court construed “bonded” to mean “bonded by the application of heat.” MARCTEC v. JOHNSON & JOHNSON 4 The accused product is a drug-eluting stent having the brand name Cypher®, for implantation into patients with narrowed or blocked coronary arteries. This stent consists of an expandable, slotted metal tube that is bonded to a matrix comprised of two polymers, poly n-butyl methacry- late (PBMA) and polyethylene-co-vinyl acetate (PEVA), and a drug having the common name sirolimus, also known as rapamycin. During a portion of the manufacturing process called “solution casting,” the polymers and the drug are dissolved in a volatile solvent and the resulting solution is sprayed onto the stents. The stents are then air-dried, allowing the solvent to evaporate and leaving the poly- mer/drug coating “bonded” to the stents. The solution casting process is performed at room temperature; no heat is applied. This is the basis for the judgment of non- infringement, for the district court construed the claims as requiring the application of heat. The district court ex- plained: Heat bonding is the only form of bonding taught by the patent[s]. The specification defines “bondable material” as “any material, suitable for use in surgi- cal applications, which can be softened and made flowable by the application of heat, and which, when softened, will become tacky and bond to other mate- rials and will flow to fill available space.” MarcTec, 2009 WL 910200, at *11 (emphasis omitted). MarcTec argues that the asserted claims do not require the use of heat, and that the doctrine of claim differentiation undermines the district court’s construction, for dependent claim 8 of the ’753 patent specifically describes the poly- meric material as one that “is bonded to the implant by the application of heat.” MarcTec observes that the district court’s construction of “bonded” renders this claim superflu- 5 MARCTEC v. JOHNSON & JOHNSON ous. Perhaps it does. However, as stated in Multiform Desiccants, Inc. v. Medzam, Ltd., 133 F.3d 1473, 1480 (Fed. Cir. 1998), “the doctrine of claim differentiation can not broaden claims beyond their correct scope, determined in light of the specification and the prosecution history and any relevant extrinsic evidence.” The specification’s discussion of bonding, in the context of the invention, is uniformly directed to heat bonding. The “Summary of the Invention” states that the components of the inventive assembly “are bond[ed] to each other by the application of heat.” ’753 patent, col.1 ll.66-67, col.2 ll.4, 8, 15. During prosecution of the patents, the Applicants limited the claimed “bonding” to heat bonding, in order to overcome the cited U.S. Patent 5,102,417 to Palmaz by arguing that: “In contrast [to Palmaz], Applicants’ implant includes a heat bondable material which is bonded to an implant by the application of heat.” [J.A. 5739.] To over- come the rejection based on Palmaz, and “[t]o highlight this distinction,” the Applicants amended the claims to recite “a polymer material which is non-flowable and non-adherent at room temperature and becomes flowable, tacky, and adherent upon the application of heat.” [J.A. 5739] Marc- Tec argues that the distinction from the Palmaz reference was not premised on the use of heat. MarcTec states that the distinction was between “bonding” the material to an implant, as in Applicants’ invention, and having the mate- rial “placed upon” the implant, as in Palmaz. MarcTec states that the Applicants had no need to, and did not, distinguish Palmaz based on heat bonding because Palmaz lacks any teaching of bonding. The district court found that the prosecution record shows heat bonding as a condition of patentability, and not merely a preferred method of bond- ing. See Honeywell Int’l, Inc. v. ITT Industries, Inc., 452 F.3d 1312, 1318 (Fed. Cir. 2006) (when a patentee consis- MARCTEC v. JOHNSON & JOHNSON 6 tently describes a particular embodiment as his invention, “[t]he public is entitled to take the patentee at his word”). Limitations clearly adopted by the applicant during prosecution are not subject to negation during litigation, on the argument that the limitations were not really needed in order to overcome the reference. When an applicant yields claim scope in order to secure allowance of the patent, the public notice aspect of the record inhibits later retrench- ment to recover what was yielded. See Norian Corp. v. Stryker Corp., 432 F.3d 1356, 1361-62 (Fed. Cir. 2005) (“[I]t frequently happens that patentees surrender more through amendment than may have been absolutely necessary to avoid particular prior art. In such cases, we have held the patentees to the scope of what they ultimately claim, and we have not allowed them to assert that claims should be interpreted as if they had surrendered only what they had to.”). Prosecution history estoppel thus prevents MarcTec from recovering claim scope that includes bonding without the application of heat. We affirm the district court’s construction that “bonded” means bonded by the application of heat. Although MarcTec argues that heat is applied, it did not present evidence to avoid the grant of summary judgment. The district court’s determination that no reasonable jury could find infringe- ment, is affirmed. AFFIRMED
