Inventor of EVS Codec for VoLTE Sues Apple for Infringement

Nearly two dozen iPhone and iPad models infringe five standard-essential patents for the enhanced voice services (EVS) codec for voice over LTE, alleged codec inventor VoiceAge in a complaint (in Pacer) in U.S. District Court in Wilmington, Delaware. Apple is guilty of direct infringement because all its listed devices “include hardware and software that implements the EVS codec” without a license, said VoiceAge Wednesday. Apple also is inducing third parties to directly infringe the patents, it said. In nearly five months of phone and email “interactions,” Apple “never expressed a willingness to take a license” on EVS on fair, reasonable and nondiscriminatory (FRAND) terms, said VoiceAge. “Instead, Apple was nonresponsive, repeatedly delayed discussions, and refused to have good faith discussions” under a nondisclosure agreement, “contrary to the letter and spirit of FRAND,” it said. VoiceAge “was left with no other choice but to initiate this lawsuit,” it said. Apple didn’t comment.
