L&P Obtains Additional IPR Decisions Confirming Patentability of Claims on Which $25 Million Infringement Verdict Was Based

The Patent Trial and Appeal Board (PTAB) issued final written decisions today in IPR2020-01207 and IPR2020-01282, confirming the patentability of certain claims of U.S. Patent No. 10,090,395 owned by Laurence & Phillips IP Law (L&P) client Acorn Semi, LLC.  The surviving claims include two claims that the petitioner, Samsung, was found to infringe in a trial in the U.S. District Court for the Eastern District of Texas in May 2021, and numerous other claims.  The infringement verdict awarded Acorn $25 million before prejudgment interest.  

The challenged claims faced a written-description-based priority-disentitlement challenge in IPR2020-01207 and obviousness challenges in IPR2020-01279.  L&P successfully defeated those challenges against the two infringed claims and other claims of the ’395 Patent. 

Today’s PTAB decisions follow decisions last month in which three infringed claims of another Acorn patent also survived multiple challenges.  “In all, five of the eight infringed claims survived following a grand total of ten IPR petitions filed by Samsung,” explained L&P partner and lead counsel on the cases, Matt Phillips. Acorn’s IPR team also includes L&P attorneys Kevin Laurence, Rachel Slade, and Derek Meeker as well as attorneys from two other firms.
