Bronze - Individuals: litigation

A compact team by market standards, An, Tian, Zhang & Partners operates as an elite squad of professionals, many of whom are both patent attorneys and qualified lawyers. The combination of prosecution and contentious experience helps clients on both ends – claims are drafted and won based on knowledge about what is most effective at the invalidation and infringement stages, while contentious proceedings can be handled by attorneys who know the prosecution history inside and out. David Tian is a seasoned litigator – big names such as Dell (China) and Daimler AG have trusted him to handle patent infringement disputes with local entities. One foreign associate on the litigation side remarks: “David and his colleague Ruifeng Li work seamlessly as part of my own team; our prompt and clear exchange of information and responsiveness makes them very easy to work with on patent instructions.”
