Firm overview:

Full-service IP firm Chofn IP has a growing presence throughout Asia and is renowned as a leader in the trademarks field. Founded in Sichuan in 2002, the firm started out as a trademark agency and later added patents to its services, which now also cover copyright, trade secrets, unfair competition and more.

The firm particularly stands out for its prosecution practice, and was recognised as a “5A-Level Trademark Agency’ for 2024 by the China Trademark Association (CTA), signifying that it is among the top 100 trademark firms in China in terms of service capability. Of its 2023 trademark applications, Chofn IP achieved a provisional approval rate of 77.65%.

The team also handles a significant volume of trademark oppositions and reviews, as well as administrative and civil litigation. In November 2024, the firm had one of its cases recognised by the CTA as one of the “Typical Trademark Cases” for 2022–2023. In this instance, Chofn IP worked closely with the Chinese Customs which detained over 240,000 integrated circuit chips bearing the ‘Hynix’ trademark and determined that they were infringing. Chofn IP represented the rights holder in the proceedings and provided expert opinions, precedents for reference and documentation to support the investigation.
