Liu & Liu is a boutique law proprietorship that focuses on intellectual property and technology practice. Its predecessor Liu & Liu LLP was co-founded by Wen Liu and David Liu, both formerly colleagues at the international law firm of Morrison & Foerster LLP. Upon David's return to Morrison & Foerster in September 2002, Wen continues his boutique practice with the assistance of several associates.

The lawyers at Liu & Liu include patent attorneys and technical associates, who practice in all aspects of intellectual property and technology law, representing domestic and foreign clients, which currently include large domestic and foreign corporations, medium-sized high-technology companies, and technology start-ups. The firm offers personal, flexible, responsive and cost-effective representations regardless of the size of the clients or matters entrusted to the firm.
