The American company Rohm & Haas Electonic Materials CMP Holdings Inc. (“R&H”) claimed that the products of NexPlanar Corporation infringed upon R&H’s Taiwan Patent No. 176078, and commenced a patent litigation in the Intellectual Property Court.  On June 2, 2016, the Court of the second instance denied R&H’s claims, finding that R&H’s patent was invalid as it lacked inventive step (non-obviousness).  This case may still be appealed according to law.  (Tsar & Tsai represented NexPlanar Corporation in obtaining the winning judgment in this case.)
