Chang Chun Petrochemical Co., Ltd. (“CCPC”) sought to invalidate all claims of the patent of Nippon Synthetic Chemical Industry Co., Ltd. (“NSCI”) (R.O.C. patent No. I356069). TIPO granted the invalidation petition and ruled that all claims of the patent were invalid on the ground that the claims lacked inventiveness.
NSCI disagreed and instituted an administrative action. On August 10, 2017, the administrative branch at the IP Court held that all claims in the NSCI’s patent were invalid by reason of lack of inventive steps (non-obviousness).
The Court upheld TIPO’s determination and dismissed NSCI’s administrative action.
Tsar & Tsai represented CCPC in both proceedings.
