Coverage: Partial.Reasoning extracted with partial coverage — some sections may be incomplete.
Plain-English summary

Align Technology sought a preliminary injunction against multiple Angelalign entities for infringement of EP 4 346 690 B1 (dental aligner treatment planning software). The Düsseldorf Local Division granted the PI against operating defendants 1, 2, 4, 5, and 6 but rejected the application against the Cayman Islands holding company (defendant 3), applying Court of Appeal precedent requiring actions beyond a typical shareholder role. The court also denied Angelalign leave to appeal a procedural order that had disregarded late-filed non-infringement arguments under Rule 9.2 RoP.

Accepted arguments
What the court agreed with — by party.

  • Infringement of EP 4 346 690 B1 by Angelalign defendants 1, 2, 4, 5, and 6 is sufficiently established for provisional measures

    ClaimantLegal basis: Art. 62 UPCA

    Note: The Düsseldorf Local Division found that the validity and infringement requirements for a preliminary injunction were met for the operating entities.

  • Defendant disagreeing with claim interpretation does not shift validity burden to patent proprietor

    ClaimantLegal basis: Art. 62 UPCA

    Note: The court held that a defendant's disagreement with the claim interpretation used in the examination does not shift the burden of substantiation and proof for invalidity to the patentee.

  • Holding company defendant (Angelalign Technology Inc., Cayman) cannot be liable absent actions beyond typical shareholder role

    RespondentLegal basis: UPC_CoA_534/2024; UPC_CoA_683/2024; UPC_CoA_19/2025 (Belkin v Philips)

    Note: Applying CoA precedent on managing director liability, the court rejected the application against the Cayman holding company because no action beyond a typical shareholder/financial holding role was alleged.

Rejected arguments
What the court did not agree with — and why.

  • Leave to appeal the procedural order disregarding late-filed arguments should be granted

    RespondentLegal basis: Rule 220.2 RoP; Rule 9 RoP

    Reason: The court denied leave to appeal because the order was closely connected to the specific circumstances of the case and consistent application of RoP did not urge clarification; the Court of First Instance's discretion on procedural matters was within proper limits.

  • Relying on combinations of claim 1 with sub-claims makes invalidity of claim 1 more likely

    Respondent

    Reason: The mere fact that the applicant relies on claim 1 combined with sub-claims does not make invalidity of claim 1 alone more likely.
