"They are great, very clear and effective."

Linked Reviews
Trade mark

Case studies show the firm successfully represented the client in an administrative litigation before the Beijing Intellectual Property Court, persuading the court to invalidate the disputed trademark “eZARA” in its entirety by arguing for a broader assessment of goods similarity beyond subclass classifications, thereby securing full protection for the client’s prior trademark “ZARA HOME”. 

Patent

Case studies show the firm successfully represented LMI Technologies in a patent infringement lawsuit in China, overcoming critical evidence-gathering obstacles imposed by confidentiality clauses to prove that a Shenzhen-based company had infringed the client's 3D smart sensor patents, while also successfully defending the validity of the core patents. Clients include Hilti and Takeda Pharmaceutical Company. 

Copyright & related rights

The firm recently succeeded in copyright infringement case for a software client.
