- 2026-04-16Infringement ActionÖffentlich
Zusammenfassung: The Paris Local Division entirely revoked European patent EP2323858 (Michelin's 'Variable surface area tire tread' patent), finding Claim 1 lacked novelty over prior art document KUNUGI (JP 2001/063323), and that dependent claims and all 14 auxiliary requests likewise failed to overcome the invalidity. Consequently, Michelin's infringement claims against Goodyear were dismissed, and Michelin was ordered to bear the legal costs.

- Novelty (Art. 54 EPC) — anticipation of Claim 1 by prior art KUNUGI (JP 2001/063323)
- Probative value of party-affiliated 'expert' affidavits treated as witness statements
- Claim construction of 'tread element' and 'spacing between lateral sipes'
- Admissibility and validity of 14 auxiliary requests (added matter, clarity, inventive step)
- Reasonable number of auxiliary requests under R. 30.1 RoP
- Revocation of dependent claims 2–14 following invalidity of independent Claim 1

KUNUGI (JP 2001/063323) is a relevant prior art document because it is the only prior art cited in EP'858's description, which expressly states that KUNUGI discloses a tire tread according to the preamble of Claim 1; the different technical problem (air-pumping noise vs. water drainage) is irrelevant for a product claim defined by structural features only
BeklagterRechtsgrundlage: Art. 54 EPC; Art. 69 EPC; Protocol on Interpretation of Art. 69 EPCFig. 1 and paragraphs [0012]–[0013] of KUNUGI disclose the 'alternating arrangement of lateral grooves' (feature 7 of Claim 1), because the sipes on each side of the longitudinal sipe are visually offset in Fig. 1 and [0013] confirms they 'may be arranged independently, at any positions on each side', meaning a non-aligned (alternating) configuration
BeklagterRechtsgrundlage: Art. 54 EPCDependent claims 2–14 are invalid because Michelin provided no substantiated arguments that they would be valid independently of Claim 1
BeklagterRechtsgrundlage: Art. 54 EPC; Art. 56 EPC; Art. 138(1) EPCAuxiliary request features F1 and F2 (water channelling / surface void) do not overcome the lack of novelty over KUNUGI because they add no structural limitation absent from KUNUGI
BeklagterRechtsgrundlage: Art. 54 EPC; Art. 123(2) EPCAuxiliary request feature F3 (height H20 between 100% and 200% of Do20) introduces added matter not supported by the application as filed (WO 276)
BeklagterRechtsgrundlage: Art. 123(2) EPCAuxiliary request feature F5 (spacing between lateral sipes 5–20 mm) does not confer inventive step over KUNUGI as the spacing selection is arbitrary and would result from routine testing
BeklagterRechtsgrundlage: Art. 56 EPC
KUNUGI is not relevant prior art because it addresses a different technical problem (air-pumping noise) rather than water drainage
KlägerRechtsgrundlage: Art. 54 EPCKUNUGI's 'bulges' would never be exposed at the tread surface, so they cannot anticipate the 'submerged grooves' that become exposed in Claim 1
KlägerRechtsgrundlage: Art. 54 EPCKUNUGI's bulges lack the capacity to drain water unlike the grooves in EP'858
KlägerRechtsgrundlage: Art. 54 EPCKUNUGI does not disclose an alternating arrangement of lateral grooves (feature 7 of Claim 1)
KlägerRechtsgrundlage: Art. 54 EPCAll relevant features of Claim 1 are not disclosed within a single embodiment of KUNUGI
KlägerRechtsgrundlage: Art. 54 EPC
