United States Patent Trial and Appeal Board (PTAB) reached a decision on May 13, 2019 which denied to all challenges to the '578 Patent held by Dasso.
The PTAB Final Decision only strengthened Dasso's '578 Patent, including the pending claims against an infringer at Delaware Federal Courts. The invalidity challenge to Dasso's '578 Patent was bought on by an infringer in an attempt to legitimatize its actions.
In a stunning rebuke, PTAB judges denied all claims by this infringer challenging the validity and patentability of Dasso's '578 U.S. patent.
