1. Letter of Credit
The jury returned a verdict in this case on November 20, 2001, awarding patent infringement damages to Plaintiff Competitive Technologies, Inc. (CTI), in the amount of $1,019,365.01, and breach of contract damages to Plaintiff Metabolite Laboratories, Inc. (Metabolite) in the amount of $3,652,724.61.1 Judgment was entered on December 3, 2001, followed by an Amended Judgment on November 20, 2002. After entry of judgment, Plaintiffs filed a motion pursuant to section 283 of the Patent Act, 35 U.S.C. § 283, requesting an order permanently enjoining Lab-Corp from performing the homocysteineonly test. The Court granted Plaintiffs’ motion for permanent injunction on November 20, 2002. Defendant Laboratory Corporation of America Holdings (Lab-Corp) then moved for an emergency stay of the injunction pending its appeal of the ease to the United States Court of Appeals for the Federal Circuit.
This Court held a hearing on LabCorp’s motion to stay the injunction on November 26 and 27, 2002. At the outset of the hearing, the Court voiced concern that patient care would be endangered if the testing were to be halted by an injunction.1 2 The Court went on to address the royalties that would be incurred during a stay of the injunction, indicating that the parties should try to reach some reasonable agreement as to a royalty to be paid during the stay period, and voicing doubt that the *1139Court itself could or should impose such a payment absent the parties’ agreement.3 The License Agreement contained two different licenses: a patent sublicense in exchange for a 6% royalty, and a know-how license in exchange for a 21.5% royalty. LabCorp’s counsel maintained throughout the November 26 and 27, 2002, hearing that while LabCorp was willing to pay CTI the 6% patent royalty, Metabolite had no right to any royalty payment for tests performed during a stay of the injunction because the injunction was issued pursuant to 35 U.S.C. § 283, which authorizes injunctions to prevent the violation of patent rights, and Metabolite is not a patent holder, but rather a patent licensee.4 Lab-Corp’s counsel noted that Metabolite had never requested an injunction premised on a breach of the License Agreement, and that there had been no presentation of evidence concerning future breach of contract damages at trial.5 LabCorp’s counsel indicated that Metabolite would have to bring another lawsuit in order to recover any breach of contract damages it incurred after trial.6 The Court agreed that Metabolite was not entitled to an injunction under the Patent Act, and asked Plaintiffs’ counsel for authority under which Metabolite could be entitled to an injunction.7 Plaintiffs’ counsel did not provide, and to date has not provided, any such authority. Rather, Plaintiffs’ counsel acknowledged that the issue of ongoing payment of the 21.5% royalty was “a challenging legal question.”8 The Court stated that if the Federal Circuit affirmed the jury verdict, then the “real solution would be” for the parties to work out a license agreement, rather than having Metabolite come into court every two or three years with a new breach of contract claim. LabCorp’s counsel agreed.9 The Court ultimately ordered from the bench that LabCorp pay the 6% royalty and put the 21.5% royalty into an escrow or trust account pending appeal.10 In the context of the 21.5% royalty the Court stated that “there are some issues that the Circuit is going to have to decide about this breach of contract case. And maybe one of the issues is going to be issues (sic) concerning future injunctive relief. I don’t know. But I think that’s an iffy area. So let’s put that someplace where it will be safe and that will satisfy defendant.”11
On January 13, 2003, the Court entered a Stipulated Order Staying Injunction Pending Appeal (Stipulated Stay Order) which modified the Order issued at oral argument. The Stipulated Stay Order ordered that LabCorp was to pay a 6% royalty to CTI for tests performed from November 1, 2002, though final disposition of the case, and was to provide Metabolite with an accounting of 21.5% of the Net Sales attributable to the tests LabCorp performed after November 1, 2001. The Stipulated Stay Order stated that Lab-Corp will “secure its obligation to pay such 21.5% amount to Metabolite (in the event it is held liable therefor in this case) with a bond or letter of credit....” The final paragraph of the Stipulated Stay Order *1140stated that the order “does not compromise or otherwise affect any claim for damages, or defenses thereto, for assays performed by LabCorp subsequent to the date of the Special Verdict in this case or during the pendency of the appeal or any remand.”
The Federal Circuit affirmed the jury verdict and Judgment on June 8, 2004.12 The Federal Circuit’s opinion did not address the issue of an ongoing royalty payment to Metabolite after entry of judgment.
Plaintiffs argue that all of the conditions of the letter of credit now have been satisfied and that the Court therefore should issue a draft on the full amount of the letter of credit. However, one of the requirements for release of funds under the letter of credit is that this Court has issued a final judgment or order stating that “the amount of the draft stated above is now due and owing to Metabolite Laboratories.” The Court has never issued such a judgment or order; to the contrary, whether LabCorp can be liable for a 21.5% royalty to Metabolite for alleged breaches of the License Agreement after the entry of judgment has never been resolved, either by this Court or by the Federal Circuit.
LabCorp argues that the License Agreement cannot form the basis for continuing breach of contract damages after the date of the judgment because the jury found that the License Agreement was terminated. Plaintiffs argue that only the 6% patent license was terminated, not the 21% know-how license. Question No. 5 on the Special Verdict Form asked:
Do you find, by a preponderance of the evidence, that LabCorp breached its license agreement by terminating it with respect to its performance of the Abbott test? [Answer: yes.]
The jury had to answer “yes” to Question No. 5 in order for it also to find that LabCorp’s performance of the Abbott test constituted patent infringement, because a licensee cannot infringe.13 However, the jury needed only to find that the patent portion of the License Agreement had been terminated to find infringement. The jury did not have to find that the know-how portion of the License Agreement, with its corresponding 21.5% royalty payment, was terminated in order to find infringement. Similarly, the jury only had to find that LabCorp breached its obligation to pay Metabolite the 21.5% royalty in order to award damages to Metabolite; it did not have to find that that portion of the License Agreement was terminated in order to ’do so.14 It is clear that LabCorp could terminate something less than the entire License Agreement: Section 4.02 of the License Agreement itself recognizes that LabCorp could “terminate this Agreement with respect to a particular licensed assay if ... a more cost effective commercial alternative is available that does not infringe a valid and enforceable claim of the Licensed Patents[.]”
*1141Further, as Plaintiffs note, because Lab-Corp’s appellate briefs discussed only whether LabCorp had terminated the patent portion of the License Agreement, which would determine whether Plaintiffs could collect damages for infringement, the Federal Circuit did not address whether the know-how license was terminated. Thus, the Federal Circuit’s determination that the License Agreement was terminated is a determination only that the patent portion was terminated, not the know-how portion. Additionally, LabCorp’s own actions indicate that the entire License Agreement has not been terminated, since LabCorp continues to pay Metabolite a 21.5% royalty on other tests covered by the License Agreement.15
The Court thus concludes that neither the jury verdict nor the Federal Circuit opinion established that the know-how license was terminated, only that the patent license was terminated. Therefore, even though the injunction was based on the Patent Act, the conduct permitted by the Stipulated Stay Order, continued performance of the tests, could constitute a continued breach of LabCorp’s obligation to pay the 21.5% royalty to Metabolite. LabCorp should have expected that if it proceeded to perform the tests during the period of the stay, and the know-how portion of the License Agreement had not been terminated, then LabCorp could be liable for breach of contract damages, in the form of the 21.5% royalty, stemming from those tests. Otherwise, there was no reason for the parties to agree to the accounting process set forth in the Stipulated Stay Order. However, there has never been a legal determination that Lab-Corp actually committed any breach after the date of the Amended Judgment, or of the amount of any resulting damages. Because there are no claims remaining in this case, the issue of whether actions taken by LabCorp subsequent to the Amended Judgment constitute breach of contract, and the amount of damages for any such breach, cannot be resolved herein as a matter of procedure. As a result, the Court is not able to state in this case, at this juncture, that the amount stated on the letter of credit is now “due and owing to Metabolite Laboratories.”16 However, LabCorp has filed a separate action, Case No. 04-cv-01662-ZLW-CBS, seeking “a declaratory judgment that LabCorp has not violated the Agreement with various conduct occurring since the time period covered by the Amended Judgment and occurring into the future.” Whether Lab-Corp committed a contract breach after the date of the Amended Judgment is appropriately resolved in Case No. 04-cv-01662-ZLW-CBS. Thus, Plaintiffs’ Motion For Court To Issue Draft On Letter Of Credit will be denied without prejudice, and Case No. 04-cv-01662-ZLW-CBS shall proceed so that the issue may be resolved therein. Should there be a final determination in Case No. 04-cv-01662-ZLW-CBS that LabCorp did breach the know-how license after the date of the Amended Judgment, then Plaintiffs may present their request concerning the letter of credit again.
II. Injunction
Once the Federal Circuit mandate issued in this ease on August 12, 2004, and *1142the injunction stay was lifted, LabCorp stopped performing homocysteine-only tests itself and instead entered into an agreement with Specialty Laboratories, Inc. (Specialty), which is licensed by CTI under the '658 Patent, for Specialty to perform homocysteine-only tests referred by LabCorp. LabCorp thereafter filed its present Motion For Clarification Of Injunction, and Plaintiffs filed their Motion For Order To Show Cause. Both motions ask the Court to determine whether Lab-Corp’s arrangement with Speciality violates the permanent injunction.
An injunction issued under the Patent Act “is only proper to the extent it is ‘to prevent the violation of any right secured by patent.’ ”17 Enjoining “noninfringing activities must be avoided.”18 Further, Fed.R.Civ.P. 65(d) provides that
Every order granting an injunction ... shall describe in reasonable detail, and not by reference to the complaint or other document, the act or acts sought to be restrained; and is binding only upon the parties to the action, their officers, agents, servants, employees, and attorneys, and upon those persons in active concert or participation with them who receive actual notice of the order by personal service or otherwise.19
The Court’s November 20, 2002, Order on Plaintiffs’ motion for permanent injunction states that “Plaintiffs seek to enjoin LabCorp from performing ‘any homocysteine-only test, including without limitation homocysteine-only tests via the Abbott method,’ ” and then proceeds to grant the motion. Though Plaintiffs’ motion had also contained language requesting that “anyone on [LabCorp’s] behalf’ be enjoined from performing the tests, the Court’s Order does not include that additional language. Because an injunction must describe the acts to be enjoined without reference to any other document,20 and ambiguities are to be resolved in favor of the enjoined party,21 the injunction, by its express terms, does not prevent LabCorp’s reference of tests to Specialty. Even if the injunction were construed to prohibit testing by “anyone on [LabCorp’s] behalf,” an injunction issued pursuant to the Patent Act can enjoin only infringing conduct, and LabCorp’s reference of tests to Specialty, which holds a license from CTI to perform the tests, does not involve any infringing act that could be enjoined. The license agreement between CTI and Specialty expressly recognizes that Specialty “conducts the business of a reference laboratory which performs diagnostic assays for ... commercial diagnostic laboratories ...”22 such as LabCorp. LabCorp may refer the homocysteine-only test to a laboratory, such as Specialty, that is licensed under the '658 patent without violating the permanent injunction.
In its July 21, 2006, supplemental brief, LabCorp adds that since filing its original motion, LabCorp has purchased Esoterix, Inc. (Esoterix), which owns a testing laboratory called Colorado Coagulation, Inc. (Colorado Coagulation) which is a licensee under the '658 Patent. Colorado Coagulation’s license agreement with *1143CTI recognizes, like Specialty’s, that Colorado Coagulation “performs diagnostic assays for ... commercial diagnostic laboratories ....”23 LabCorp requests that the Court clarify whether the injunction permits LabCorp to perform the tests directly by relying on the Colorado Coagulation license. For the same reasons discussed above with respect to Specialty, the Court clarifies that LabCorp may refer homocysteine-only tests to licensee Colorado Coagulation, which is LabCorp’s subsidiary and thus a separate entity,24 without violating the injunction. However, LabCorp did not succeed to any rights under the CTI-Colorado Coagulation license agreement merely by purchasing Esoterix,25 and thus LabCorp may not itself perform homocysteine-only tests without violating the injunction.
Accordingly, it is
ORDERED that Plaintiffs’ Motion For Court To Issue Draft On Letter Of Credit (Doc. No. 345) is denied without prejudice. It is
FURTHER ORDERED that Defendant’s Motion For Clarification Of Stay Order And Related Letter Of Credit (Doc. No. 338) is granted to the extent set forth herein, and the issue of whether LabCorp breached the License Agreement after the date of the Amended Judgment shall be resolved in Case No. 04-cv-01662-ZLW-CBS. It is
FURTHER ORDERED that Defendant’s Motion For Clarification Of Injunction (Doc. No. 339) is granted to the extent set forth herein, and (1) LabCorp may refer the homocysteine-only test to a laboratory, such as Specialty, that is licensed under the '658 patent without violating the permanent injunction issued in this case, and (2) LabCorp may refer homocysteineonly tests to Colorado Coagulation, Lab-Corp’s subsidiary and thus a separate entity, without violating the injunction, but LabCorp may not itself perform homocysteine-only tests without violating the injunction. It is
FURTHER ORDERED that Plaintiffs’ Motion For Order To Show Cause (Doc. No. 379) is denied. It is
FURTHER ORDERED that the parties shall pay their own costs and attorneys’ fees with regard to the four motions addressed in this Order.

. Although the Federal Circuit stated that "[a] material breach” of a license "constitutes termination,” the authorities cited by the court in support state only that a material breach gives rise to the right to terminate. See Metabolite, 370 F.3d at 1370 (citing Apex Pool Equip. Corp. v. Lee, 419 F.2d 556, 562 (2nd Cir.1969); Ross-Simons of Warwick, Inc. v.

. Given the Court's determinations herein, it would seem that LabCorp indeed would be liable for breach of contract damages to Metabolite for homocysteine-only tests LabCorp performed itself after the date of the Amended Judgment. However, again, there is no such claim for breach before the Court in this case, nor can there be, since final judgment was entered long ago.
