On July 19, 2017, the U.S. Patent Trial & Appeal Board (PTAB) ruled in favour of 64 Audio (formerly 1964 Ears), finding all claims of U.S. Patent No. 8,897,463, held by Jerry Harvey Audio Holdings (JH Audio), unpatentable. A copy of the PTAB’s ruling can be found here.
The claims found to be unpatentable are directed to a dual high frequency driver in-ear monitor. JH Audio asserted the claims against 64 Audio in a lawsuit filed in December 2014. 64 Audio sought PTAB review of the dual high frequency driver claims in January 2016.
64 Audio says it is “happy with the PTAB’s ruling, as it solidifies the company’s long-held belief that the dual high frequency driver claims are invalid.” Founder and CEO of 64 Audio, Vitaliy Belonozhko, adds, “From day one we were very confident in our ability to prevail.”
