Zusammenfassung in einfacher Sprache

NJOY Netherlands B.V. sought to revoke EP 3 504 991 B1 (Juul Labs International, a vaping device cartridge with dual condensation chambers) before the Paris Central Division, relying on Cohen, Chen, and Thompson as prior art. The court dismissed the revocation action, finding the patent novel and inventive; it declined to assess Chen/Thompson-based obviousness attacks not raised by NJOY as the revocation scope is defined by the claimant. The court also reaffirmed that inventive step is an objective inquiry and that parties may substantiate initial arguments when challenged by the opponent.

Angenommene Argumente

Was das Gericht akzeptiert hat — nach Partei.

Inventive step must be evaluated objectively; subjective knowledge of inventors or parties is irrelevant
BeklagterRechtsgrundlage: Art. 56 EPC
Hinweis: Paris Central Division held that inventive step under Art. 56 EPC is an objective inquiry; the 'person skilled in the art' reference excludes subjective considerations.
Court does not evaluate revocation reasons not raised by the claimant
BeklagterRechtsgrundlage: Art. 76(1) UPCA
Hinweis: Claimant defines scope of revocation evaluation; court applied dispositive principle and declined to assess obviousness over Chen/Thompson as starting points since claimant had not raised this.
Patent valid for novelty and inventive step over asserted prior art
BeklagterRechtsgrundlage: Art. 54, 56 EPC
Hinweis: Court dismissed revocation action, finding the claimed vaping cartridge (with dual condensation chambers and specified mouthpiece configuration) novel and inventive.
Party may further substantiate initial argument in second submission where opponent challenged it in reply
BeklagterRechtsgrundlage: RoP Preamble para. 5
Hinweis: Court balanced front-loading obligation with fairness: if a party raises an argument in its first submission and the opponent challenges it, the first party may further substantiate in its second submission.

Zurückgewiesene Argumente

Was das Gericht nicht akzeptiert hat — und warum.

EP 3 504 991 B1 lacks novelty over Cohen
KlägerRechtsgrundlage: Art. 54 EPC
Begründung: Features 1.2–1.8 of claim 1 disputed between parties; court found it unnecessary to fully resolve whether Cohen discloses all disputed features because inventive step finding sufficed; revocation action dismissed.
Claim 1 invalid for lack of inventive step
KlägerRechtsgrundlage: Art. 56 EPC
Begründung: Claim 1 involves an inventive step; dependent claims 2–11 also involve inventive step via dependency on claim 1 or 3.
