On August 1, 2024, the Federal Circuit affirmed the Patent Office's final decision confirming that all claims (1-8) of U.S. Patent 10,491,679 were unpatentable. Owned and asserted by Voice Tech Corp, the ’679 patent relates to voice-activated computing. The patent was asserted against Linux-based technology from Mycroft AI for using open source, voice-related features. This invalid patent has been blamed for the closure of Mycroft AI.
