The Patent and Trademark Law Firm is the oldest intellectual property law firm in China with a history of more than 50 years.

The history of the firm can be traced back to January 1957. At that time, with the authorization of the State Council, the China Council for the Promotion of International Trade established an agency under its Legal Affairs Department to handle foreign-related trademark matters. Until the mid-1980s, the agency was the only trademark agency in the country. From the late 1970s to the early 1980s, China began to establish a patent system. Authorized by the State Council, the China Council for the Promotion of International Trade began to establish a patent agency in 1980, sending lawyers and professionals to study and study the patent system abroad, organizing training for domestic patent agency professionals, and participating in the drafting of relevant laws and regulations. The Patent Agency Department of the China Council for the Promotion of International Trade was formally established in 1984 and authorized by the State Council to become China's first foreign-related patent agency. In 1993, the above two agencies merged to form the China Council for the Promotion of International Trade Patent and Trademark Office.
