In an opinion issued December 4, 2023, the U.S. Court of Appeals for the Federal Circuit[1] reversed a lower court’s denial of Intel Corporation’s (“Intel’s”) motion for leave to amend its answer to assert a new license defense in a patent infringement suit brought by VLSI Technology LLC (“VLSI”). The decision paves the way for Intel to make the case that it received a license to VLSI’s patents when a company that Intel had an existing license with became affiliated with VLSI due to its acquisition by an investment management firm.
