UPC_CoA_393/2025

The Court of Appeal allowed AorticLab's appeal and set aside the Munich Local Division's order granting Emboline's application for security for costs. The CoA held that Art. 69(4) UPCA provides no legal basis for a security for costs at the request of the claimant in an infringement action in response to a defendant's counterclaim for revocation. Allowing such security would unreasonably restrict the defendant's right to raise an invalidity defence by means of a mandatory counterclaim.
