Summary

In an order of 27 October 2026 (UPC_CoA_71/2026), the judge-rapporteur of the Court of Appeal orders the reimbursement of EUR 61,150 to Qualcomm. Qualcomm had paid EUR 90,300, the amount displayed by the CMS, for its cross-appeal against the Munich Local Division’s decision of 11 March 2026 on the counterclaim for revocation (UPC_CFI_450/2024, EP 1 875 683). The appeal fee in such cases is the first-instance fee plus 10%; for a value of EUR 12 million, it was EUR 26,500 at first instance, i.e. EUR 29,150 on appeal.
