Versata Software, Inc. v. Callidus Software, Inc.

United States Court of Appeals for the Federal Circuit
771 F.3d 1368 (2014)


Versata Software (plaintiff) brought suit against Callidus Software (defendant), alleging infringement of three patents. Callidus filed a counterclaim, asserting three of its own patents against Versata. Callidus then filed a set of petitions with the Patent Office challenging the claims of Versata’s three patents. Callidus challenged every claim of one of the patents, and a subset of claims of the second two patents. Callidus simultaneously sought a stay of all of the trial court’s proceedings. The trial court granted a stay as to the first patent but denied a stay as to the other two patents. The trial court applied the statutory four-factor test and found that each factor weighed against granting a stay on those issues. Callidus filed an interlocutory appeal from the court’s denial of the stay. The United States Court of Appeals for the Federal Circuit heard the appeal.
