Clint Conner




Clint’s practice focuses on intellectual property with an emphasis on patent litigation, licensing (including “standard essential patents”), inter partes reviews (“IPRs”), and patent enforcement strategies. He has successfully handled over 60 patent disputes in federal courts around the country, at the International Trade Commission, and at the Patent Trial and Appeal Board. 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. IP litigation while living and working in Tokyo, Japan. 

Clients place their confidence in Clint to manage their most important issues, and he delivers.  For example, he recently led a Dorsey team to a complete defense victory in a huge, complex 11-patent litigation relating to LCD technology brought against a client by a wholly owned subsidiary of Taiwanese heavyweight Foxconn.  Our team worked cooperatively with our co-defendant and an intervenor and utilized an array of defenses and IPRs to eliminate the asserted patents one-by-one.   

Before attending law school, Clint gained practical experience as an engineer for three years with Bell Labs (now Nokia). Clint understands that at the heart of any intellectual property dispute is a business objective, and he is careful to consider his clients’ business objectives every step of the way in any legal dispute to achieve at a winning result while also avoiding unjustified risk.  

His experience includes patent issues relating to the following technologies:  Internet, networking, Wi-Fi, H.264, semiconductor manufacturing, photolithography, hard disk manufacturing, medical devices, physician efficiency programs, LCDs, LEDs, CCFLs, 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.
