QRG, Ltd., a/k/a Quantum Research Group, Ltd. v. NARTRON CORPORATION DC

In a final written decision handed down last month, the Patent Trial and Appeal Board (PTAB) ruled that Samsung had failed to show that any of the instituted claims of the challenged patent are unpatentable (IPR2016-00908). The patent owner, UUSI, LLC (d/b/a Nartron), responded first by moving to reopen the Western District of Michigan case that it had filed against Samsung in February 2015. That court has denied the request, continuing the existing stay until any appeals from the PTAB’s decision become final. Nartron has also responded to the favorable PTAB decision by filing a new suit against Apple (2:17-cv-13798), accusing the company of infringing the challenged patent through the provision of products (e.g., certain iPads, iPhones, and iPods) based on the operation of their touchscreens.
