About

Provided by Wanhuida Intellectual Property

Wanhuida is a trailblazer with the mix of legal expertise and result-oriented practical approach.

In 2025, it has quite a few cases that are recognised by Chinese courts as innovative or exemplary, including:

SPC Annual Report on Application of Law in IP Cases: Representing a leading Chinese game livestreaming platform in reversing unfavorable non-use cancellation decision against its iconic device mark in class 35 through administrative suits. The case is groundbreaking for the judicial guidance to trademark owners in the live commerce industry as to how to prove use under “sales promotion for others”.

SPC Annual Report on Application of Law in IP Cases: Advising a leading Chinese drug maker in winning civil suits against a rival insulin maker and an ex-shareholder that preemptively registered and used similar trademarks, adopted similar trade names and trade dress. The courts unanimously found trademark infringement and unfair competition could be established, recognized the well-known trademark status of the client’s prior marks, ordered cessation, and awarded damages of RMB 60.82 million.

SPC IP Court Abbreviature of Adjudication: Representing Carlsberg in successfully invalidating the design patent infringing on its V8 registered trademark filed in prior to the design at issue. The case went through invalidation action and two instances of court proceedings. The SPC, which serves as the court of appeal in the administrative proceeding, ruled in favor of Carlsberg.
