The Federal Circuit has made a pivotal decision regarding the scope of inter partes review (IPR) estoppel. In a case that involved Ioengine LLC, the court affirmed a jury’s decision to invalidate the company’s flash drive patents. This determination clarifies that estoppel arising from IPR proceedings applies solely to arguments grounded in printed publications. This nuanced interpretation is a significant development for patent litigators and corporations heavily engaged in IPR processes.
In this case, the jury’s invalidation of Ioengine’s patents was based on the premise that the patented technology was already publicly accessible. This ruling by the Federal Circuit further solidifies this approach to evaluating patent claims under IPR proceedings.
