In this webinar, our experts will explore key issues currently shaping UPC litigation. The session will examine the UPC’s approach to inventive step and how it compares with the EPO, as well as practical considerations when raising preliminary objections. It will also address how sensitive and confidential information can be managed during UPC proceedings.
HLK’s client, Establishment Labs, has prevailed in a preliminary objection at the Unified Patent Court. In this case, Establishment Labs is suing GC Aesthetics group and its Belgian distributor at the UPC for infringement of its European Patent No. 3 107 487 B1 relating to soft tissue body implants.
We’re pleased to have achieved a strong result for our client Establishment Labs S.A. in a recent UPC infringement action brought by CooperSurgical.
After the patent at issue was revoked by the EPO, CooperSurgical withdrew its UPC case and argued that each party should bear its own costs. The UPC disagreed and held that a withdrawing claimant, especially following EPO revocation, should be treated as the unsuccessful party, awarding Establishment Labs substantial costs.
