Heading: The Interlocutory Appeal

Text: As we explained in the interlocutory appeal opinion in this case, “‘[n]ot all cases involving a patent-law claim fall within the Federal Circuit’s jurisdiction.’” Microsoft I, 696 F.3d at 881 (quoting Holmes Grp., Inc. v. Vornado Air Circulation Sys., Inc., 535 U.S. 826, 834 (2002)). The Federal Circuit, we noted, would have jurisdiction over Motorola’s appeal of the anti-suit injunction “only if it would have jurisdiction over a final appeal in the case under 28 U.S.C. § 1295.” Id. (citing 28 U.S.C. § 1292(c)(1)). Looking to Microsoft’s complaint, we explained that this action is not one “arising under any Act of Congress relating to patents,” 28 U.S.C. § 1338(a), but rather “sounds in contract and involves the district court’s diversity jurisdiction.” Microsoft I, 696 F.3d at 881. We therefore concluded that we had jurisdiction over the interlocutory appeal, thereby necessarily deciding also that we would have jurisdiction over a final appeal of the breach of contract claim. Id.
