Summary: The Düsseldorf LD dismissed Inficon's infringement action against Elitech over EP 3 567 356 (the METRUM gas detector does not realise feature 5, a buffer chamber permitting homogeneous mixing; the claimant's measurements were inconclusive, so no specific contesting under R. 171.2 RoP was needed) and dismissed Elitech's counterclaim for revocation, holding claim 1 novel over CC1 and inventive. Each side bears the costs of the claim it lost; the interim costs request was refused; values EUR 1m and EUR 1.5m, cost ceiling EUR 400,000.
