VALVE ACTUATING DEVICE OF A VALVE, LIQUID TANK OF A LIQUID TREATMENT APPARATUS, AND A LIQUID TREATMENT APPARATUS

InfringementMain Infringement ActionMunich LDInfringementCase Closed
Plain-English summary

Brita SE (Germany) sued AQUASHIELD EUROPE s.r.o. and related entities for infringing EP 2 387 547 B1, a patent for a valve actuating device used in water filter treatment apparatus (filter cartridges). The Munich Local Division found infringement of the amended patent, rejected the exhaustion defence (defendants' standalone replacement cartridges constitute re-manufacture rather than permitted repair), and granted an injunction; costs were split 50% each on the infringement claim and 90/10 (claimant/defendants) on the revocation counterclaim.

Accepted arguments
What the court agreed with — by party.
  • Patent EP 2 387 547 B1 as amended (auxiliary request) is valid and infringed by AQUASHIELD replacement filter cartridges

    ClaimantLegal basis: Art. 25 UPCA; Art. 65 UPCA

    Note: Court maintained the patent in amended form and found infringement, granting an injunction effective from 23 May 2019.

  • Purpose indications in a device claim require only that the device be suitable for the stated purpose; actual use for that purpose is not required

    ClaimantLegal basis: Art. 54 EPC; purposive claim construction

    Note: Court held that purpose indications define a device by its suitability; for novelty, only whether the prior art device is inherently suitable or requires modification is relevant.

  • Replacement of an entire cartridge (key functional component) by a third-party constitutes re-manufacture, not exhaustion-protected repair

    ClaimantLegal basis: Art. 29 UPCA

    Note: Court distinguished exhaustion-protected repair from re-manufacture: replacement that does not preserve the identity of the specific patented product constitutes re-manufacture and falls outside exhaustion.

Rejected arguments
What the court did not agree with — and why.
  • Exhaustion: defendants' filter cartridges are legitimately supplied replacement parts for products placed on market by Brita

    RespondentLegal basis: Art. 29 UPCA

    Reason: Exhaustion covers permitted use including normal maintenance and restoration, but not acts amounting to re-manufacture of the patented product. Replacing a key functional component that embodies the patented invention goes beyond permitted repair and constitutes re-manufacture.

  • Patent claims as originally granted are valid (revocation counterclaim)

    RespondentLegal basis: Art. 65 UPCA

    Reason: Patent was maintained in amended form via auxiliary requests; original claims were partially found invalid but the revocation counterclaim succeeded only to the extent the patent required amendment.

  • Where patentee defends only via auxiliary requests (amended claims), court must first consider whether original claims are partially invalid under Art. 65(3) UPCA

    RespondentLegal basis: Art. 76(1) UPCA; Art. 65(3) UPCA

    Reason: Court held that where the patentee defends only via auxiliary requests and not the original claims, there is no obligation under Art. 76(1) UPCA to examine partial invalidity of the original claims.

Claim construction notes

EP 2 387 547 B1 is a valve actuating device for a liquid treatment (water filter) apparatus. The court construed purpose indications in the device claim as requiring suitability for the stated function. The exhaustion defence was analysed around whether defendants' standalone replacement filter cartridges maintain or destroy the identity of Brita's patented device; the court found they constitute re-manufacture rather than repair.
