Plain-English summary

NJOY Netherlands B.V. successfully revoked EP 3 498 115 B1 (Juul Labs International vaping device cartridge patent) before the Paris Central Division on grounds of added matter under Art. 138(1)(c) EPC / Art. 123(2) EPC. All of Juul Labs' twelve auxiliary amendment requests were rejected — most for failing to overcome the added matter defect, and auxiliary request (2)d additionally for being unclear, exceeding a reasonable number, and lacking supporting argument. The court confirmed that Art. 65(3) UPCA does not require evaluating partial allowability of amendment requests.

Accepted arguments

What the court agreed with — by party.

Patent EP 3 498 115 B1 invalid for added matter under Art. 123(2) EPC
ClaimantLegal basis: Art. 138(1)(c) EPC; Art. 123(2) EPC
Note: Paris Central Division (Section 1) found the patent added matter not disclosed in the parent application; all of Juul Labs' auxiliary requests to amend the patent were rejected.
Court may limit patent by amendment and revoke only in part under Art. 65(3) UPCA without being obliged to evaluate if amendment can be allowed in part
ClaimantLegal basis: Art. 65(3) UPCA; R. 50(2) RoP
Note: Court held Art. 65(3) UPCA pertains only to the granted patent; within an amendment application, a claim set is either allowable as a whole or not — there is no obligation to evaluate partial allowability.

Rejected arguments

What the court did not agree with — and why.

Auxiliary requests (2)a through (2)d to amend the patent to overcome added matter objection
RespondentLegal basis: R. 50.2 RoP; R. 30.1(c) RoP; Art. 65(3) UPCA
Reason: Most auxiliary requests rejected because the added matter defect was not overcome; auxiliary request (2)d was additionally rejected as unclear (no defined order for claim combinations), unreasonable in number (exceeding the 12-request limit treated as reasonable), and unsupported by argument.
