In September 2026, Chang Tsi & Partners’ Shanghai Office, together with the Shanghai Intellectual Property Services Association, hosted the seminar in Pudong New Area, Shanghai, under the theme “Brand and Content Protection in the AI Era.” The event brought together practitioners from IP authorities, in-house legal and IP teams, industry professionals and the legal sector to discuss key developments under China’s revised Trademark Law and the evolving boundaries of rights in AI-generated content.
The aforementioned case is of positive significance for combating counterfeits, protecting the legal rights and interests of right holders, and maintaining market order. It has also strengthened our determination to help our clients to protect their rights and interests with the highest level of service and more precise customized IP protection solutions.
