The Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office (PTO) yesterday issued a final written decision in case no. PGR2020-00079 confirming the patentability of all claims of U.S. Patent No. 10,728,653 (the “’653 Patent”) owned by ClearOne Inc. (NASDAQ:CLRO), a leading global provider of audio and visual communication solutions. Shortly after the ’653 patent issued in mid-2020, Shure, Incorporated initiated the case in yet another attempt to disrupt ClearOne’s patent rights, but the PTAB rejected each and every one of Shure’s seven challenges.
The ’653 Patent covers aspects of ClearOne’s revolutionary innovations in beamforming microphone arrays (BMAs). Specifically, the ’653 Patent relates to “a ceiling tile combined with [a] beamforming microphone array” that includes acoustic echo cancellation and “adaptive acoustic processing that automatically adjusts to a room configuration.”
