    VerletztUnterlassung angeordnetNichtigkeit (Hauptsache)Counterclaim for revocation

    The infringement action against Defendants 1-3 (TCL Deutschland GmbH & Co. KG, TCL Deutschland Verwaltungs GmbH, and TCL Operations Polska) was predominantly successful: they were found to directly infringe claim 1 of EP 3 296 274 and are subject to injunction, recall, removal, destruction, and information obligations. The infringement action against Defendant 4 (TCL Belgium, SA) was dismissed for lack of demonstrated operational control over the infringing subsidiary. The counterclaim for revocation was dismissed in its entirety, with the patent maintained as granted.

Angenommene Argumente
Was das Gericht akzeptiert hat — nach Partei.

  • Chemical analyses (XRF and ICP) of TCL 32L5A TVs purchased for the German market confirmed that glass sheets in tested LCD-panels have a composition falling within claim 1 of the patent-in-suit, establishing infringement by Defendants 1-3.

    KlägerRechtsgrundlage: Art. 25(a) UPCA; claim 1 of EP 3 296 274

  • Risk of further infringement is presumed from established past infringement and is not rebutted absent a cease-and-desist declaration with contractual penalty clause.

    KlägerRechtsgrundlage: Art. 63(1) UPCA; CoA UPC_CoA_789/2025 (Dyson v Dreame)

  • The subject-matter of claim 1 does not extend beyond the content of the original/earlier application as filed; added matter ground rejected.

    KlägerRechtsgrundlage: Art. 138(1)(c) EPC; Art. 123(2) EPC

  • Patent is disclosed sufficiently clearly and completely; sufficiency ground rejected.

    KlägerRechtsgrundlage: Art. 138(1)(b) EPC; Art. 83 EPC

  • Claim 1 is novel over WO'997 and WO'810 and involves inventive step over US'158, JP'535 and JP'247; all invalidity attacks dismissed.

    KlägerRechtsgrundlage: Art. 138(1)(a) EPC; Art. 54, 56 EPC

  • Injunction is not disproportionate given Defendants can source glass sheets from licensed suppliers and patent only has a short remaining term.

    KlägerRechtsgrundlage: Art. 63(1) UPCA; Art. 42 UPCA; Art. 3(2) Enforcement Directive
Zurückgewiesene Argumente
Was das Gericht nicht akzeptiert hat — und warum.

  • TCL Belgium (Defendant 4) exercised operational control over TCL Operations Polska (Defendant 3) and is therefore liable for Defendant 3's infringement.

    KlägerRechtsgrundlage: Art. 25(a) UPCA

  • Chemical analyses of US market samples (EDS) were sufficient to establish infringement in Germany and that US and European models are identical.

    KlägerRechtsgrundlage: Art. 25(a) UPCA

  • All current LCD-TVs produced by Defendants for the German market do not infringe the patent-in-suit, rebutting risk of repetition.

    BeklagterRechtsgrundlage: Art. 63(1) UPCA

  • Injunction should be restricted to specific TV models or LCD-panel suppliers.

    BeklagterRechtsgrundlage: Art. 62(1) UPCA; Art. 25(a) UPCA

  • Permanent injunction is disproportionate (reference to public interest and supply chain concerns).

    BeklagterRechtsgrundlage: Art. 63(1) UPCA; Art. 42 UPCA

  • Enforcement of the decision should be made dependent on provision of a security of at least EUR 5,000,000.

    BeklagterRechtsgrundlage: Art. 82(2) UPCA; R. 352.1, 354.1 RoP

  • Interim award of damages/costs of EUR 150,000 should be granted.

    KlägerRechtsgrundlage: Art. 68 UPCA; R. 119 RoP

  • Publication of the decision in public media should be permitted at Defendants' expense.

    KlägerRechtsgrundlage: Art. 80 UPCA
