On May 12, 2021, the U.S. Court of Appeals for the Federal Circuit affirmed a Patent Trial and Appeal Board (PTAB) decision in the patent infringement matter of Uniloc 2017 LLC v. Apple Inc., in which the Federal Circuit found that 20 out of the 25 patent claims filed were invalid and patent ineligible.
Uniloc’s patents in dispute relate to “systems and methods for policing Voice over Internet Protocol (VoIP) features, such as caller-ID, call waiting, and multi-line services.”
