Opinions

MOORE, Circuit Judge.

Endo Pharmaceuticals, Inc. (Endo) appeals from the district court’s order denying its motions for a preliminary injunction to prevent Roxane Laboratories, Inc. (Roxane), Actavis Inc., and Actavis South Atlantic LLC (Actavis) from marketing and selling their respective generic drug products during the pendency of this litigation. Because the district court erred in concluding that Roxane and Actavis (Ap-pellees) had an implied license to practice the asserted patents, and because Appel-lees do not have an express license, we vacate and remand.

Background

Endo sells Opana® ER, which are branded extended-release tablets containing a painkiller called oxymorphone. The asserted patents are listed in the Approved Drug Products with Therapeutic Equivalence Evaluations (Orange Book) entry for Opana® ER. Two of the asserted patents, U.S. Patent Nos. 8,309,122 (the '122 patent) and 8,329,216 (the '216 patent), are each continuations of the same parent application and are directed to extended-release oxymorphone compositions and methods of treating pain using those compositions. The third patent-in-suit, U.S. Patent No. 7,851,482 (the '482 patent), is not related to the other two patents. It recites purified oxymorphone compositions and methods of making those compositions. The '122 and '216 patents are at issue in both appeals, and the '482 patent is at issue only in the Actavis appeal.

Prior to this litigation, Endo sued Appel-lees for patent infringement under 35 U.S.C. § 271(e)(2)(A) based on their Abbreviated New Drug Applications (AN-DAs) to market generic versions of Opa-na® ER-the same products as those at issue in these appeals. The first set of [1373]*1373lawsuits settled after Endo granted to Ap-pellees a license and a covenant not to sue. The settlement and license agreement between Endo and Roxane (Roxane Agreement) defines “Licensed Patents” as follows:

(a) any [U.S.] patents that are both (i) now owned by Endo ... and (ii) issued as of the Effective Date of this Agreement, including the Opana® ER Patents,
(b) any [U.S.] patent applications that claim priority to the Opana® ER Patents, including any continuation, continuation-in-part and divisional patent applications that claim priority to Opa-na® ER Patents, and
(c) any patents resulting from the reissue or reexamination of patents or patent application of patents or patent applications comprised within clauses (a) and (b) ...

J.A. in appeal no. 2013-1662 (Roxane J.A.), at 4973 § 1.16 (emphases added). The Roxane Agreement defines “Opana® ER Patents” as U.S. Patent Nos. 5,662,-933, 5,958,456, and 7,276,250. Id. § 1.20.

Pursuant to the agreement, Endo granted Roxane a covenant that it would not assert that Roxane’s generic versions of Opana® ER “infringe[ ] the Licensed Patents” and a license “under the Licensed Patents ... to make, use, have made, sell, offer to sell, import and use” those generic products. Roxane J.A. 4978 §§ 4.1(a),(b) (emphases added); see also Roxane J.A. 4974 §§ 1.28, 1.29. Finally, the Roxane Agreement includes a “No Implied Rights” provision stating that Endo does not grant to Roxane any license or right “whether by implication, estoppel or otherwise, other than as expressly granted herein.” Rox-ane J.A. 4949 § 4.4. The settlement and license agreement between Endo and Ac-tavis (Actavis Agreement) is similar. The Actavis Agreement includes a grant of a license, a covenant not to sue, and a “No Implied Rights” provision, but covers one additional patent not included in the Rox-ane Agreement and not relevant to this appeal. J.A. in appeal no. 2013-1658 (Ac-tavis J.A.), at 4893-908.

The patents that are the subject of this litigation issued after Endo’s agreements with Appellees. The '122 and '216 patents issued to Endo and the '482 patent was acquired by Endo. Endo again sued Appel-lees for patent infringement under 35 U.S.C. § 271(e)(2)(A) and moved for a preliminary injunction to prevent the marketing and sales of their generic oxymorphone formulations. Appellees opposed on the theories of express license and implied license by reason of legal estoppel. With regard to the latter, Appellees argued that Endo attempted to deprive them “of the benefit of [the] earlier bargain.” Roxane J.A. 4823; see also Actavis J.A. 2717.

At a joint hearing, the district court commented that “this is a highly unfair and unjust situation if ... infringement of the new patents would stop the marketing and permitting process that was going on by Actavis and Roxane.” Actavis J.A. 6411. The court held that “as a matter of law ... Endo is estopped from claiming that the activity of Actavis and Roxane, which has gone on for a substantial period of time, is now suddenly barred because of these new patents.” Id. The court therefore denied Endo’s motions. Endo Pharm., Inc. v. Actavis Inc., C.A. No. 12-cv-8985-TPG (S.D.N.Y. Sept. 18, 2013), ECF No. 35.

Endo appeals. We have jurisdiction under 28 U.S.C. § 1292(a)(1).

Discussion

We review decisions to grant or deny a preliminary injunction for an abuse of discretion, which may be established [1374]*1374when a district court based its decision on an error of law. Sanofi-Synthelabo v. Apotex, Inc., 470 F.3d 1368, 1374 (Fed.Cir. 2006). “To the extent the court’s decision is based upon an issue of law, we review that issue de novo.” Id. Whether legal estoppel has been created and whether an implied license exists are questions of law. Wang Labs., Inc. v. Mitsubishi Elees. Am., Inc., 103 F.3d 1571, 1578, 1580 (Fed.Cir. 1997). “The interpretation of a Settlement Agreement, i.e., a contract, is a question of law that we [also] review de novo.” Augustine Med., Inc. v. Progressive Dynamics, Inc., 194 F.3d 1367, 1370 (Fed.Cir. 1999). “The burden of proving that an implied license exists is on the party asserting an implied license as a defense to infringement.” Id.

I. Express License

Endo argues that the district court abused its discretion in denying Endo’s motions for a preliminary injunction. Endo contends that the plain language of the agreements, which limit “Licensed Patents” to several enumerated patents and applications claiming priority to them, does not grant Appellees an express license to practice the asserted patents. It argues that the “No Implied Rights” provision further makes clear that the agreements do not cover the asserted patents. In the district court, both Actavis and Roxane argued that they have an express license to practice these newly issued patents. In this appeal, Actavis no longer presents this argument, although Roxane continues to do so.
