The Tesla v. Avanci case began in 2023. Tesla filed a lawsuit against Avanci and InterDigital, a licensor in its 5G automotive SEP patent pool, in the High Court of England and Wales. Tesla sought declarations that three SEP patents held by InterDigital were either invalid or not essential to the 5G standard, and requested the court to determine the FRAND licensing rate for the Avanci 5G automotive SEP patent pool. Unlike Vestel's request in the UK for determination on the AA patent pool's royalty rate, Tesla approached the matter more from a contract law perspective, arguing that if the patent pool violated FRAND obligations, its market sales in the UK would be harmed accordingly. Tesla also sought to have the three SEPs declared invalid and not essential, seemingly linking the case to potential infringement damages to strengthen its connection to the UK.
