Recent trials to determine FRAND rates include Optis Cellular Technology LLC v Apple Retail in which Mark Chacksfield KC was instructed to act for the successful claimant. Jaani Riordan was instructed to act for the defendant in Nokia v OPPO, a multi-patent multi-trial action relating to mobile telecoms patents for 4G/5G functionality and FRAND rates.
