L&P Prevails in IPR Trials of Memory Chip Patent

The Patent Trial and Appeal Board (PTAB) ruled today that L&P client Polaris Innovations Ltd. prevailed completely and partially, respectively, in two inter partes review (IPR) trials requested by NVIDA Corp. against U.S. Patent No. 8,161,344.  The patent, which relates to error coding, particularly in a computer memory system, is one of several at issue in infringement litigation brought by Polaris against NVIDIA.  

Polaris won IPR2017-01781 completely and won IPR2017-01346 partially in a mixed decision that confirmed the patentability of at least 10 challenged claims.  Matt Phillips of Laurence & Phillips IP Law and lead counsel on the cases commented, “Our work on this pair of cases was a team effort by myself, Kevin Laurence, and Derek Meeker.  Kevin took the lead on a tricky swear-behind issue, and Derek took the lead on complex technical issues on which we ultimately prevailed.”
