Opinion:
PER CURIAM.
In related district-court actions, plaintiff Galderma Laboratories, L.P., along with other patent-asserting parties, alleged that the Abbreviated New Drug Applications submitted by Mylan Pharmaceuticals Inc., Lupin Limited, and Impax Laboratories, Inc., each constituted an act of infringement under 35 U.S.C. § 271(e)(2). After a four-day bench trial addressing five patents, the district court granted the patent-asserting parties relief on one patent: it rejected invalidity challenges to the asserted claims of that patent and held that those claims would be infringed by the proposed manufacture, use, and sale of generic versions of Oracea®. Research Found. of State Univ. of New York v. Mylan Pharms. Inc., 809 F.Supp.2d 296 (D.Del.2011). The district court denied relief on the other patents, some of which it held invalid as to all of the asserted claims. Id. at 307. Appeals and cross-appeals are now before this court.
We affirm the district court in every respect, except with regard to three dependent claims of the Amin Patents, namely, claims 2 and 14 of U.S. Patent No. 5,789,395 and claim 2 of U.S. Patent No. 5,919,775. And we find only that issue to warrant discussion, given the extensive analysis of the district court. We conclude that the district court erroneously (though understandably) applied its finding of anticipation of the independent claims of the Amin Patents without addressing the additional claim elements of the three specified dependent claims. We vacate the district court's invalidity judgment as to those dependent claims and remand for further proceedings.
The Amin Patents claim methods for treating medical conditions, such as inflammatory disorders, characterized by increased endogenous nitric oxide production. Specifically, the Amin Patents claim the use of tetracyclines — a class of antibiotics that includes doxycycline — to inhibit nitric oxide production or nitric oxide syn-thase expression or activity. Galderma licensed the Amin Patents and, along with co-assignees New York University and the Research Foundation of the State University of New York, asserted twelve claims from the Amin Patents. Three of the dependent claims — claims 2 and 14 of the '395 patent and claim 2 of the '775 patent — require, in addition to the nitric-oxide limitations of the independent claims, that the administered "tetracycline compound has substantially no anti-microbial activity."
During trial, Mylan identified eight pri- or-art references that disclosed treating periodontitis or rheumatoid arthritis, both chronic inflammatory disorders, with between 40 and 200 mg of a tetracycline daily. The district court found that the "higher dosage" prior-art references, i e., daily tetracycline dosages between 60 and 200 mg, inherently anticipated the Amin Patents because "[t]he record shows that at these dosages . [nitric oxide] production or [nitric oxide synthase] expression will be inhibited." See Research Found., 809 F.Supp.2d at 329. The district court made no findings on the prior-art references that disclosed lower tetracycline dosages, between 40 and 60 mg. Id. And the district court made no findings on whether any of the prior art contained the additional limitations found in the asserted dependent claims, including whether any of the eight prior-art references disclosed the limitation of claims 2 and 14 of the '395 patent and claim 2 of the '775 patent that the "tetracycline compound has substantially no anti-microbial activity." Id.
A determination that a patent claim is invalid as anticipated under 35 U.S.C. § 102 "requires that a prior art reference disclose every limitation of the claimed invention, either explicitly or inherently." Liebel-Flarsheim Co. v. Medrad, Inc., 481 F.3d 1371, 1381 (Fed.Cir.2007). What suffices to anticipate one claim may not suffice for another claim containing different elements. In particular, when a dependent claim adds an element to an independent claim, and the challenger sufficiently raises the point, an anticipation analysis must examine the additional element— which, by definition, it will not have been necessary to analyze in assessing anticipation of the independent claim not containing the added element. See Dayco Prods., Inc. v. Total Containment, Inc., 329 F.3d 1358, 1370-71 (Fed.Cir.2003).
In invalidating all of the asserted claims of the Amin Patents, the district court found that certain references inherently disclosed use of a tetracycline to inhibit endogenous nitric-oxide production, but it never determined, as required, whether those treatments also had "substantially no anti-microbial activity." This limitation made claims 2 and 14 of the '395 Patent and claim 2 of the '775 Patent materially different from the independent claims for the purpose of determining validity, and the district court erred by not addressing it.
We reject the suggestion of the patent-asserting parties that this court not only vacate but reverse on these claims, a suggestion based on the premise that the record conclusively establishes "that the four Higher Dosage References relied upon cannot meet the substantially no antimicrobial effect limitation." Br. for New York Univ. at 44. Even if the larger dosage references did not anticipate the three dependent claims at issue for that reason — a question on which we express no view — reversal would not be appropriate because the district court made no findings about what the lower dosage references disclosed expressly or inherently. Without such findings, this court cannot rule out anticipation of the three dependent claims (let alone any other preserved grounds of invalidity of those claims). See Research Corp. Techs., Inc. v. Microsoft Corp., 536 F.3d 1247, 1254-55 (Fed.Cir. 2008). Thus, we go no further than to vacate the invalidity judgment as to these three claims.
We do so despite readily understanding how the district court likely came to overlook the additional elements of these dependent claims. In their post-trial papers, the patent-asserting parties mentioned the additional elements of these claims in a proposed finding of fact, Galderma's Post-Trial Proposed Findings of Fact at 23, ¶ 162 Research Found. of State Univ. of New York, 809 F.Supp.2d 296 (Civ. No. 09-184), but focused their arguments on the independent claims, specifically, on whether the eight identified prior-art references inherently disclosed use of a tetracycline to inhibit endogenous nitric-oxide production. See Galderma's Post-Trial Brief at 22-24, Research Found. of State Univ. of New York, 809 F.Supp.2d 296 (Civ. No. 09-184). Despite the patent-asserting parties' scant attention to the distinction between these dependent claims and their independent claims, however, the patent-challenging parties in this court did not argue waiver or the like, but addressed the point entirely on its merits. Indeed, they admitted that the patent-asserting parties presented the distinct challenge to the dependent claims. See Letter from Appellant Mylan Pharmaceuticals Inc., Research Found. of State Univ. of New York v. Mylan Pharmaceuticals Inc., No. 13-1047 (Fed.Cir. July 22, 2013).
For the foregoing reasons, we affirm the district court judgment except as to claims 2 and 14 of the '395 Patent and claim 2 of the '775 Patent. We vacate the district court's judgment of invalidity of those claims and remand for further proceedings consistent with this opinion.
