Koninklijke Philips N.V. v Asustek Computer Incorporation & Ors [2019] EWCA Civ 2230 (17 December 2019)

Koninklijke Philips N.V. v Asustek Computer Incorporation & Ors [2019] EWCA Civ 2230 (17 December 2019)

The Court of Appeal upheld the High Court's finding that claim 10 of the 525 patent was not obvious over Shad. The skilled person would not be prompted by Shad to implement differential gains at the base station, and the judge was entitled to scrutinise the evidence and reject the argument that such implementation was an obvious alternative. The judge made no error of principle in his approach to obviousness, and the appeal was dismissed.
