ADAPTIVE SENSOR SAMPLING OF A COLD CHAIN DISTRIBUTION SYSTEM
BITZER Electronics sought revocation of Carrier Corporation's EP 3 414 708 (cold chain monitoring apparatus with adaptive sensor sampling). The Paris Central Division dismissed the revocation action as against the patent amended by auxiliary request II, finding that the prior art did not teach or suggest adjusting the sampling rate based on environmental altering or user-induced events. The court also set important procedural precedent on the admissibility of late-filed documents and the scope of permissible patent amendments in partial revocation proceedings.
Amended claim 1 (auxiliary request II) is inventive over the cited prior art because none of the documents teach adjusting sampling rate based on environmental altering or user-induced events
BeklagterRechtsgrundlage: Art. 56 EPCHinweis: The court found no motivation in the prior art to solve the technical problem by adjusting the sampling rate based on event triggers, rather than by other means such as more sophisticated devices or reduced measuring frequency.
Patent proprietor entitled to amend challenged claims by inserting features from non-challenged claims
BeklagterRechtsgrundlage: Art. 65 UPCA; Rule 30 RoPHinweis: The court established that where a patent is only partially attacked, the proprietor may propose amendments to challenged claims by inserting features from non-attacked claims.
Late-filed prior art documents MB2 and MB4 should be admitted and undermine inventive step
KlägerRechtsgrundlage: Art. 56 EPC; Rule 9.2 RoP (advancement of proceedings)Begründung: The late-filed documents did not relate to the defence raised by the opponent or the amendment application, and therefore did not constitute a legitimate response that would justify late filing; additionally MB2 was published after the priority date.
Request to amend patent is inadmissible with respect to non-challenged claims
KlägerBegründung: The court ruled the amendment request inadmissible only as to the non-challenged claims, but admissible as to challenged claims, so this argument was only partially accepted.
New grounds for revocation introduced in reply to defence constitute permissible arguments
KlägerRechtsgrundlage: Rule 9.2 RoPBegründung: Grounds that could have been included in the initial statement of revocation are inadmissible if they do not relate to the defence or the amendment application.

The contested claim 1 as amended under auxiliary request II requires a plurality of environmental sensors (specifically monitoring temperatures) each with a dedicated power source, an event detector for environmental altering or user-induced events, and a controller that adjusts the sampling rate depending on those events. The court did not extensively discuss individual term construction but analysed the distinctiveness of the event-triggered sampling rate adjustment feature.
