Last July, the UK High Court dismissed a case filed by Tesla that sought the declaration of a fair, reasonable, and nondiscriminatory (FRAND) license rate covering Avanci, LLC’s entire 5G pool—declining to make such a determination through certain claims against Avanci itself or by forcing member InterDigital, Inc. to serve as a “representative” of the other standard essential patent (SEP) owners participating in that pool. Now, a divided UK Court of Appeal has upheld the dismissal of those claims, prompting a sweeping dissent from Lord Justice Richard Arnold.
