    Summary: The Central Division Milan revoked European Patent EP 4 185 356 in its entirety with effect on all UPC Contracting Member States, finding that claim 1 as granted and auxiliary request 1 lack novelty over prior art document D2 (WO 2015/193833 A2). Auxiliary requests 2 to 13 were found not allowable due to lack of clarity under Art. 84 EPC, and the application to amend the patent was dismissed.

    Show the legal issues (6)
    • Novelty (Art. 54 EPC) — claim 1 and AR1 lack novelty over prior art D2 (WO 2015/193833 A2)
    • Claim interpretation — meaning of 'manifold', 'connector', 'swivel connection', 'selective retainer means'
    • Admissibility and allowability of auxiliary requests
    • Clarity (Art. 84 EPC) — AR2-AR13 lack clarity regarding whether gas tube is a mandatory component
    • Added matter (Art. 123(2) EPC) — raised but left open as clarity/novelty dispositive
    • Mapping of prior art components to claim features when different labels are used in prior art

    Revocation ActionPublic

    Summary: The Milan Central Division (full panel: Postiglione, Klein, Roselinger) rejected Fisher & Paykel's request to introduce auxiliary requests 2A to 13A as subsequent amendments to the patent (EP 4 185 356) in the revocation proceedings. The Court held that under R. 50.2 and R. 30.2 RoP, subsequent amendments are only allowed on an exceptional basis; the preclusive nature of the front-loaded system means that amendments must be made in full at the earliest stage. The efficiency of proceedings is not a sufficient reason to allow subsequent piecemeal amendments.

    • Front-loaded system and preclusive nature of pleadings
    • Admissibility of auxiliary requests

Accepted arguments
What the court agreed with — by party.

  • Frame portion 102 in D2 constitutes a 'manifold' in the sense of claim 1, and component 114 (labelled 'manifold' in D2) constitutes a 'connector', such that all features of claim 1 as granted are directly and unambiguously disclosed by D2

    ClaimantLegal basis: Art. 54 EPC; novelty assessment based on overall disclosure of prior art document

  • AR2-AR13 lack clarity because the newly added feature referring to 'the aperture fluidically connects the gas tube to the manifold' leaves the skilled person in doubt whether the gas tube is a mandatory component of the nasal cannula

    ClaimantLegal basis: Art. 84 EPC; Rule 50.2 RoP

  • Swivel connection is not limited to single-axis rotation; both single-axis and multi-axis rotational arrangements fall within claim 1

    ClaimantLegal basis: Art. 69 EPC; Protocol on Interpretation of Art. 69 EPC

  • Gas tube is not a mandatory component of the nasal cannula as claimed in claim 1 as granted

    ClaimantLegal basis: Claim interpretation under Art. 69 EPC
Rejected arguments
What the court did not agree with — and why.

  • Component 114 (labelled 'manifold' in D2) must be mapped to the 'manifold' of claim 1, and the frame portion 102 cannot constitute the manifold because it does not direct gas from the inlet at the connector-manifold connection to the nasal prong outlets

    RespondentLegal basis: Claim interpretation under Art. 69 EPC

  • 'Swivel connection' in claim 1 is limited to rotation about a single axis of rotation

    RespondentLegal basis: Claim interpretation under Art. 69 EPC

  • The nasal cannula requires that the gas supply tube not be disconnected during use (continuous airflow requirement)

    RespondentLegal basis: Claim interpretation under Art. 69 EPC

  • AR1 is not novel over D2 only if component 114 is mapped as the 'manifold'; under the defendant's preferred mapping AR1 is novel

    RespondentLegal basis: Art. 54 EPC

  • AR1 was inadequately substantiated and therefore inadmissible

    ClaimantLegal basis: Rule 50.2 RoP
