The Court of Appeal has upheld the ruling of Birss J in Unwired Planet v Huawei.
The Court of Appeal has given judgment on the appeal brought by Huawei against judgments which resolved a number of issues surrounding FRAND licences – see Unwired Planet International Ltd & Anor v Huawei Technologies Co Ltd & Anor  EWCA Civ 2344.
