Accepted arguments
What the court agreed with — by party.

  • UPC has universal jurisdiction over all defendants domiciled in any UPCA Contracting Member State under Art. 4 Brussels I Recast (departing from prior panel position in UPC_CFI_387/2025)

    ClaimantLegal basis: Art. 4, Art. 71a, Art. 71b(1) Brussels I Recast; Art. 31 UPCA

  • Defendant 3 (Dutch importer to EU including Spain) serves as anchor defendant for Defendant 1 under Art. 8(1) Brussels I Recast for Spanish national part of patent

    ClaimantLegal basis: Art. 8(1), Art. 71b(2) Brussels I Recast

  • Feature 1.6 ('slot formed by overlap of first end and second end of wall') is not limited to overlapping ends of plates building the wall; the Dazzle Attachment literally infringes claims 1 and 11

    ClaimantLegal basis: Art. 69 EPC; Protocol on Interpretation of Art. 69 EPC; Art. 25(a) UPCA

  • Patent is more likely than not novel and inventive over prior art O1 (DE1942806A1), O2 (US 5,868,148) and O3 (US 5,212,366) since those documents do not disclose features 1.9–1.11 (Coanda-effect airflow wrapping hair without mechanical rotation)

    ClaimantLegal basis: Art. 138 EPC

  • Balance of interests favours Applicant due to direct competition, price erosion risk, and difficulty enforcing damages against Chinese manufacturer

    ClaimantLegal basis: Art. 62(2) UPCA; Rule 211.3 RoP
Rejected arguments
What the court did not agree with — and why.

  • Defendant 3's role as EU authorized representative under GPSR creates sufficient connection to subject UK-based Defendant 5 to UPC jurisdiction as co-defendant under Art. 8(1) Brussels I Recast

    ClaimantLegal basis: Art. 8(1), Art. 71b(2) Brussels I Recast; GPSR (EU) 2023/988

  • Defendant 3 is liable as intermediary or joint tortfeasor under UK/English law for sales in UK (including Northern Ireland) because its EU representative role is a prerequisite for marketing in Northern Ireland

    ClaimantLegal basis: Art. 62, Art. 63(1) UPCA; GPSR (EU) 2023/988; Windsor Framework

  • The patent is invalid due to insufficient disclosure and lack of novelty/inventiveness over O1, O2 and O3

    RespondentLegal basis: Art. 138 EPC

  • The Dazzle Attachment does not infringe feature 1.6 because it uses multiple individual airflow outlets rather than a slot formed by overlapping wall ends

    RespondentLegal basis: Art. 69 EPC; Art. 25 UPCA

  • Defendants' interests must prevail in the balance because the attacked products are non-infringing and an injunction would massively impair their market position as direct competitors

    RespondentLegal basis: Art. 62(2) UPCA; Rule 211.3 RoP
