Patent infringement lawsuit against producer of wood pellets

Date: 14 October 2020


A patent infringement lawsuit has been filed by Maucher Jenkins lawyers against a major German producer of wood pellets on behalf of the German company HD-Pelletstechnologie GmbH & Co. KG.


The lawsuit is based inter alia on the German patent DE 10 2013 022 395 B3.The patent protects the technology known and appreciated on the market for the production of HD® and HD®+ pellets. The patent is characterised, among others, by the fact that the cutting system has a radial guide surface at a distance from the ring die.


This invention is a groundbreaking innovation that makes it possible to produce pellets of previously unachievable quality. The technology makes it possible to produce pellets with an much more homogeneous length distribution, which among others prevents dust from breaking pellets and improves the combustion efficiency. This saves costs and protects the environment.


Last year, HD-Pelletstechnologie had obtained facts which, in the opinion of the patent holder, infringe the aforementioned patent. As a result, the Regional Court in Düsseldorf issued a temporary injunction upon request for an inspection to be carried out by a court-appointed expert. In the meantime, HD-Pelletstechnologie has filed a lawsuit in the main action. The matter is now pending before the Regional Court in Düsseldorf.


The holder of HD® technology licenses its technology and wishes to protect its licensees by taking decisive action against infringers. The owner therefore intends to continue to take all possible steps against unlawful use of the HD® technology in the future. In addition to high costs for the companies concerned, the persons behind the decisions may also be held responsible. If a person with knowledge of a patent knowingly uses it without the consent of the patent owner, this may not only result in claims under civil law, but may also lead to criminal prosecution under Art. 142 of the German Patent Act.
