Shure Wins Latest Round in ClearOne Patent Dust-Up

Shure has announced that the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office (PTAB) in its inter partes review of Shure’s U.S. Patent No. 9,565,493 confirmed the patentability of several new amended patent claims in response to a challenge initiated by ClearOne. The ’493 patent protects the architecture of Shure’s MXA910 product line, which ClearOne had asserted infringed on its patents for drop-ceiling-mounted microphone technology.

“Shure is pleased with the PTAB’s decision, which recognizes and protects the technological innovations of our MXA910 products,” said Jim Schanz, vice president of global sales, Integrated Systems at Shure. “Our focus is always on customers, and we have established a longstanding reputation for providing them with high-quality, reliable audio products that meet their changing needs. The PTAB’s findings recognize our extensive investment in intellectual property and reinforce Shure’s position at the forefront of innovation in the industry.”

On August 14, 2020, the PTAB recognized certain inventive and innovative aspects in Shure’s nested ring microphone design, confirming original patent claims 6 and 34 of the ’493 patent. The PTAB also granted Shure 11 new amended claims for the ’493 patent that protect the structure and form factor of Shure’s MXA910 product line. Although the PTAB’s decision also found that other original claims of the ’493 patent are unpatentable, in granting these new amended claims, the PTAB confirmed the patentability of innovations embodied in Shure’s MXA910 products.

ClearOne’s challenges to Shure’s new amended claims were based in part on ClearOne’s own U.S. Patent No. 9,813,806 and its published application. The PTAB found Shure’s new amended claims patentable over both of these ClearOne references, recognizing the conceptual differences between Shure’s inventive microphone array structure and ClearOne’s different approach in its ’806 patent and published application.
