Intellectual property

Nokia Technologies Oy & Anor v OnePlus Technology (Shenzhen) Co, Ltd & Ors

Oppo is not already licensed nor an ETSI Clause 6.1 Beneficiary; Clause 6.1 requires the patentee to make a FRAND offer capable of acceptance, not to grant a licence immediately. The patentee may choose between FRAND options, and Oppo's willingness is qualified by its insistence on Chongqing terms. Seeking an injunction is not an abuse of dominance as Oppo can avoid it by accepting FRAND terms set by the English court.
