Optis Cellular Technology LLC & Ors v Apple Retail U.K. Limited & Ors

Optis Cellular Technology LLC & Ors v Apple Retail U.K. Limited & Ors

The Court of Appeal (majority: Arnold LJ, Nugee LJ) held that the High Court erred in finding claims 1 and 4 of the patent obvious. The skilled person, upon consulting NRC3, would have been taught away from using an LCG due to clear warnings against their use, and there was no sufficient reason for the skilled person to disregard those warnings. Therefore, the invention was not obvious over Ericsson and the appeal was allowed, setting aside the revocation of the patents.
