Gao Law Professional Corporation, which operates together with Gao IP Agency Ltd. under the name Gao IP, is an intellectual property practice based in downtown Toronto at 18 King Street East. The firm is run by founder Lei Gao, a Barrister and Solicitor admitted in Ontario who is also a lawyer admitted in New York State, a registered Canadian patent agent, and a registered Canadian trademark agent. Before starting this practice, Lei Gao worked at Ridout and Maybee LLP, an intellectual property firm in Canada, and in the intellectual property department at Baker McKenzie, a global law firm. Lei Gao also previously worked as a Canadian trademark examiner.
The practice covers patents, industrial designs, trademarks, and copyright for clients in Canada, the United States, and internationally, handling matters from patentability opinions and application drafting through prosecution, licensing, and enforcement. Because Lei Gao is a registered trademark agent in Canada and a member of the New York bar, the firm can represent applicants directly before the Canadian Intellectual Property Office and the United States Patent and Trademark Office, and has arranged patent filings in jurisdictions including Europe, Asia, Latin America, and Australia.
