Tokyo, Japan / Newport Beach, CA – August 24, 2010 – Renesas Electronics Corporation (TSE: 6723) and Acacia Research Corporation (Nasdaq: ACTG) announced today that Renesas Electronics, a premiere supplier of advanced semiconductor solutions, and Acacia, a leader in patent licensing, have entered into a strategic patent licensing alliance. Pursuant to this relationship, those patents selected by Acacia and Renesas Electronics from Renesas Electronics' portfolio of over 40,000 patents and patent applications will be assigned to Acacia for patent licensing.
