Clint Conner




Clint’s practice focuses on intellectual property with an emphasis on patent litigation, inter partes reviews, and patent enforcement strategies. Although he has remained focused on U.S. intellectual property law throughout his career, he brings an international perspective, having spent nearly five years representing companies in U.S. patent litigation while living and working in Tokyo.  Before attending law school, Clint was an engineer for three years with Lucent Technologies’ Bell Labs (now Alcatel-Lucent).

He has experience handling patent issues relating to Internet and networking technology, semiconductor manufacturing, hard disk manufacturing, medical devices, physician efficiency technology, LCD technology, rare earth magnets, digital cameras, optics, imaging and printing, wireless network protocols, GUI interfaces, navigation systems, visual search technology, online real-time auction systems, interactive programming guides, and software.
