Lübbers Anlagen und Umwelttechnick GmbH v. Relco Wet & Dry B.V., accelerated patent proceedings before the District Court of The Hague, the Netherlands, 25 January 2012, Case No. 387236 / HA ZA 11-451
On 25 January 2012, the District Court of The Hague ruled in the case brought by Lübbers against Relco. Lübbers acted as the exclusive licensee for EP 1 105 202 (relating to an annular ring injector aimed at cleaning air purification chambers), which patent is owned by Dutch patent holder and licensor Korporam B.V. Lübbers sought an injunction against Relco for patent infringement, but saw the invoked patent partially invalidated instead. Relco attacked the patent on grounds of lack of clarity / insufficiency, lack of novelty and lack of inventive step.
The Court ruled that although lack of clarity arguments under Article 84 EPC are not as such admissible in national proceedings, but that such arguments can indeed lead to invalidation on grounds of insufficiency (Article 83 EPC). Claim 4 is invalidated for that reason.
