The court assessed validity in the form restricted by the EPO under Art. 105a EPC during the proceedings and upheld the patent, establishing that Art. 105a(2) EPC has no effect on UPC revocation jurisdiction.

    RespondentLegal basis: Art. 65 UPCA; Art. 138 EPC

  • When the EPO restricts a patent under Art. 105a EPC during pending UPC revocation proceedings, the court must assess validity of the patent in its restricted form

    RespondentLegal basis: Art. 105a EPC; Art. 65 UPCA

  • Art. 105a(2) EPC has no effect on UPC revocation proceedings and does not preclude UPC jurisdiction

    RespondentLegal basis: Art. 105a(2) EPC; Art. 32 UPCA
Rejected arguments
