The Unified Patent Court (UPC) Paris Local Division handles a case involving Sun Patent Trust (claimant) against Vivo Mobile Communication entities (defendants) concerning the alleged infringement of European Patent No. EP3852468, owned by the claimant. The claimant seeks damages of 5 million euros for the alleged infringement, which the defendants do not contest. The case also involves a counterclaim for revocation. The panel comprises judges with expertise in legal and technical aspects.

During the interim conference, key issues such as claim interpretation, validity, and infringement of the patent were discussed. The court reviewed the definition of the 'skilled person' and examined specific claim features related to mobile communication standards. The oral hearings are scheduled for September with both public and non-public sessions to address technical and confidential FRAND matters. The outcome will hinge on claim construction, patent validity, and alleged infringement by the 4G+ compatible Vivo devices. The total value in dispute is set at 10 million euros.
