Rhodia’s patent maintained valid by final court decision

  발표일자:2013-07-08

Beijing High People’s Court recently made out the second instance decision, reversing the first instance judgment and upholding the SIPO decision which declares Rhodia’s patent valid. Lifang partners, Xie Guanbin and Sun Xi, represented Rhodia in this invalidation action against HySci (Tianjin) Special Materials Co., Ltd. (“HySci”), which lasted for 6 years before this eventual victory.

Previously, SIPO’s Patent Re-examination Board twice issued decisions on the subject patent. The first one declared the patent invalid and Rhodia appealed, winning court support in both instance proceedings. When the second SIPO decision found the patent valid, HySci appealed and was partly supported by the first instance court. Rhodia appealed and Beijing High Court reversed the previous court decision. The patent is now valid and sound.
