Plain-English summary

Meril Italy and Meril GmbH/Life Sciences sought revocation of Edwards Lifesciences' EP 3 646 825 (prosthetic heart valve) on inventive step grounds. The Paris Central Division rejected all invalidity attacks against the patent as limited by Edwards' auxiliary request II, which narrowed the claims to require an all-hexagonal cell frame in a specific alloy. The court identified 'Levi' as the closest prior art and found no obvious motivation to combine prior art to arrive at the claimed structure, dismissing the revocation while splitting costs 60/40 because the patent was only saved by in-proceedings amendment.

Accepted arguments
What the court agreed with — by party.

  • Patent maintained in amended form under auxiliary request II is valid over all asserted invalidity grounds

    RespondentLegal basis: Art. 56 EPC

    Note: Edwards successfully defended EP 3 646 825 by limiting the patent to a frame made entirely of hexagonal cells from a specific nickel-cobalt-chromium-molybdenum alloy, which the court found inventive over the prior art.

  • Fontaine's article does not teach that reduced crimping profile derives from all-hexagonal cell geometry

    RespondentLegal basis: Art. 56 EPC

    Note: The court found that the Fontaine reference could not be relied on to show the specific technical effect was attributable to the hexagonal geometry, defeating the obviousness attack based on that document.

Rejected arguments
What the court did not agree with — and why.

  • Lack of inventive step based on 'Levi' as closest prior art combined with disclosure of hexagonal cells in heart valves

    ClaimantLegal basis: Art. 56 EPC

    Reason: The court applied the problem-solution approach using 'Levi' as closest prior art and found that the combination did not render the amended claim obvious.

  • All invalidity grounds raised against amended auxiliary request II are well-founded

    ClaimantLegal basis: Art. 56 EPC

    Reason: The court found all grounds of invalidity unfounded as against the patent in its amended form (auxiliary request II).

Claim construction notes

The court construed the amended claim as requiring a prosthetic heart valve frame made up entirely of hexagonal cells (each defined by six struts including two parallel side struts, two lower converging angled struts, and two upper converging angled struts) composed of a specific nickel-cobalt-chromium-molybdenum alloy, mounted on a balloon delivery catheter. The amendment narrowed the original claim by specifying the alloy composition and the all-hexagonal cell requirement.
