Art. 69(4) UPCA permits an order for security for costs only against the applicant
Art. 69(4) UPCA permits an order for security for costs only against the applicant, but not in the applicant’s favour. “Applicant” is the party that initiates the relevant proceedings by lodging the procedural act by which those proceedings are commence (see orders of 28 April 2026, UPC_CoA_21/2026, Suinno v Microsoft; 9 December 2025, UPC_CoA_622/2025, Hefei v Grundfos; 30 October 2025, UPC_CoA_8/2025, Oerlikon v Bhagat; 20 June 2025, UPC_CoA_393/2025, AorticLab v Emboline). Accordingly, at first instance, there is no legal basis for granting security for costs at the request of a claimant in infringement proceedings or in a revocation action.
