On 5 Nov 2021, Ms. Spring Chang, representing the Chinese legal industry, was invited to the TM5 Annual Meeting 2021 held by the world five largest intellectual property (IP) offices and WIPO.

The annual meeting mainly discussed the challenges and responses to the pandemic and the post-pandemic era, especially changes of application behaviour and improvement measures taken by IP offices. 

The TM5 is a collaborative framework composed of the China National Intellectual Property Administration (CNIPA), the European Union Intellectual Property Office (EUIPO), the Japan Patent Office (JPO), the Korean Intellectual Property Office (KIPO), and the U.S. Patent and Trademark Office (USPTO). Its purpose is to undertake cooperation efforts to simplify and where possible, harmonise practices and programs for the mutual benefit of trademark applicants and IP offices.
