ON Semiconductor is the first company targeted by WiLAN subsidiary Collabo Innovations, LLC, an entity created at the end of 2013. Semiconductor devices made by ON Semi and its subsidiary Aptina, particularly CMOS image sensor products, are accused of infringing the patents asserted (5976907; 6166405; 7696543). The three patents-in-suit are from a portfolio that WiLAN acquired from Panasonic in December 2013, and the patents were assigned directly to Collabo. All three relate to solid-state imaging devices used in CMOS circuits.
