CLIENT: Hermès International
TESTIMONIAL: Congratulations on this positive decision and the recognition of not only the fame and the well-known status of our house mark and its Chinese equivalent but also the recognition on the combined use of our iconic elements including orange color, “H” character, horse device, carriage patterns as well as the display of Hermes’ products constitute unfair competition. The damages obtained is also good news and a very good point. I believe this decision is one of the first concerning our orange color. I can’t wait to see you to celebrate this beautiful decision. Another reason to drink Champagne!

CLIENT: a leading company in life science industry
TESTIMONIAL: Thanks again for the great news on Wednesday! This has been a long project, and a long wait for the court decision, but it is really exciting to see that we have reached our goals to get the desired verification from the court. I would like to thank Wanhuida for the great work and in particularly yourself and your team for guiding us through the process and representing us before the Shanghai court. And I really look forward to keeping working with you on this and other cases.

TESTIMONIAL: Thank you for this good news. On behalf of myself and my colleagues of Stäubli Sargans, I would like to congratulate you on this success. You did a very good job and very professional preparation. Of course we don't get what we asked for but our rights are recognized and the infringer can no longer reject the accusation of infringement. This result strengthens our will to fight and gives us the energy to continue the fight.

Ren Haiyan (Ms)
