On March 13, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision in Intel Corp. v. PACT XPP Schweiz AG reversing a final written decision of the Patent Trial and Appeal Board (PTAB) that found Intel had failed to show that PACT’s patent claims were invalid for obviousness. In reversing, the Federal Circuit ruled that the PTAB improperly rejected Intel’s “known technique” rationale supporting a motivation to combine prior art references under the flexible analysis set out by the U.S. Supreme Court’s landmark 2007 obviousness ruling in KSR v. Teleflex.
