A notable shift – Software survives patent-eligibility test

Description

Abstract: Patents covering software can face an uphill battle when challengers contend the software is actually a patent-ineligible abstract idea. In Mentone Solutions LLC v. Digi Int’l Inc., the U.S. Court of Appeals for the Federal Circuit recently upheld one such patent. This article sheds some light on how these patents can withstand judicial scrutiny. Mentone Solutions LLC v. Digi Int’l Inc., No. 21-1202 (Fed Cir. Nov. 15, 2021); Two-Way Media Ltd. v. Comcast Cable Communications, 874 F.3d 1329, 124 U.S.P.Q.2d 1521 (Fed. Cir. 2017); CosmoKey Solutions GmbH & Co. KG v. Duo Security LLC, No. 20-2043 (Fed Cir. Oct. 4, 2021).
