On June 28, 2022, Voice Tech Corporation’s request for rehearing of IPR2020-01018 was denied by the Patent Trial and Appeal Board (PTAB). The IPR was filed against U.S. 10,491,679 on June 5, 2020, was instituted on December 14, 2020, and received a final written decision holding all claims invalid on December 13, 2021. The ’679 patent relates to voice-activated computing. The patent is currently asserted against Mycroft AI Inc. for using open source, voice-related technologies. This denial comes after the Board previously rejected Voice Tech's precedential opinion panel (POP) request.
