*995 ON MOTION

ORDER

Warner Chilcott Company, LLC moves to dismiss the cross-appeal of Lupin Ltd. and Lupin Pharmaceuticals, Inc. (collectively, “Lupin”). Lupin opposes.

I.

This case involves a dispute over whether Lupin’s Abbreviated New Drug Application to market its generic version of Generess® infringes U.S. Patent No. 6,667,050 (the “'050 patent”) owned by Warner Chilcott and listed in the Orange Book.

Following a bench trial, the district court entered its judgment, which, provided in relevant part:

IT IS on this 28th day of April 2014 ORDERED as follows:

1. Judgment is entered in favor of Plaintiff on Plaintiffs claims of infringement and Defendants’ counterclaim of noninfringement.

2. The Court finding that the '050 patent is invalid as obvious, and judgment is entered in favor of Defendants on Defendants’ counterclaim of invalidity.

After Warner Chilcott appealed from the judgment, Lupin filed a cross-appeal, challenging the district court’s infringement and definiteness determinations. Warner Chilcott moves to dismiss the cross-appeal as improper.

II.

When a district court has entered a judgment of invalidity as to all asserted claims, a cross-appeal is unnecessary and improper to assert additional grounds of invalidity or non-infringement. See, e.g., Aventis Pharma S.A. v. Hospira, Inc., 637 F.3d 1341, 1343-44 (Fed.Cir. 2011); Type-Right Keyboard Corp. v. Microsoft Corp., 374 F.3d 1151, 1157 (Fed.Cir. 2004). Lupin nonetheless contends that its cross-appeal was proper because the district court “entered two distinct judgments — one as to infringement and one as to invalidity.”

That the district court entered a judgment with separate line items addressing infringement and invalidity does not suggest Lupin’s cross-appeal was proper. The form of the judgment is not what matters; what matters is whether the party was adversely affected by the judgment. See TypeRight, 374 F.3d at 1156-57 (“A party may ‘cross-appeal if adversely affected by the appealed judgment in some particular which it seeks to have modified.’ ”) (quoting Beloit Corp. v. Valmet Oy, 742 F.2d 1421, 1424 (Fed.Cir. 1984)).

Radio Steel & Mfg. Co. v. MTD Products, Inc., 731 F.2d 840 (Fed.Cir. 1984), upon which Lupin most heavily relies, is easily distinguishable. There, the district court issued a judgment that the patent was “valid but not infringed by the defendant’s products.” Id. at 843. Since the defendant would need to modify the judgment to market other products without fear of infringing the patent, we concluded that a cross-appeal would be necessary. Id. at 844. Here, by contrast, Lupin is not adversely affected because it cannot be liable for infringement of an invalid patent. See, e.g., Richdel, Inc. v. Sunspool Corp., 714 F.2d 1573, 1580 (Fed.Cir. 1983). Thus, unlike Radio Steel & Mfg. Co., this case does not involve circumstances where the defendant is seeking to expand its rights under the judgment, and therefore is outside the circumstances where filing a cross-appeal is proper.

However, the “appellee may, without taking a cross-appeal, urge in support of a decree any matter appearing in the record, although his argument may involve an at *996 tack upon the reasoning of the lower [tribunal] or an insistence upon matter overlooked or ignored by it.” United States v. Am. Ry. Express Co., 265 U.S. 425, 435, 44 S.Ct. 560, 68 L.Ed. 1087 (1924). Lupin may thus make its arguments regarding non-infringement and indefiniteness in its response brief as an appellee. See, e.g., Datascope Corp. v. SMEC, Inc., 879 F.2d 820, 822 n. 1 (Fed.Cir. 1989) (an appellee may assert alternative grounds for affir-mance supported by the record).
