LexField Law Offices

Firm overview:

IP-focused firm LexField Law Offices was established in Beijing in 2004 and serves a broad range of clients from China, the US, Europe, Japan and other jurisdictions. Originally operating as Jan Liu & Associates, the firm rebranded in 2009 following a merger between its IP litigation team and a patent team.

The firm’s Trademark and Dispute Resolution Group counsels clients on brand-related legal matters pertaining to product launches and trade dress, prosecutes international and national trademark applications, and provides trademark clearance legal work.

LexField attorneys are also experienced in handling trademark disputes including oppositions and cancellations before the Trademark Office and Trademark Review and Adjudication Board. When matters reach the court, the team collaborates with the IP Litigation Group which has acted on a significant number of IP cases, many of which have set legal precedents in China.
