Wastewater treatment: HEUKING successfully enforces Veolia patent
In its ruling of January 12, 2026, the Regional Court of Düsseldorf ruled in the first instance that two companies of the Supratec Group and five managing directors infringed the German part of European patent EP 2 473 258 B1. The defendants have appealed against the ruling of the Regional Court. A decision on the patent nullity action filed by Supratec with the Federal Patent Court in Munich is still pending.
The Regional Court assessed the manufacture and sale of certain gas distributors and hollow fiber membrane modules equipped with these gas distributors. Supratec usually refers to them as "HA10," "HA15," and "HA20." The judges ruled that the defendants unlawfully used the patented technology.
HEUKING attorneys Dr. Anton Horn and Dr. Birthe Struck and patent attorney Dr. Detlef Raasch represented Veolia in the proceedings. "The Düsseldorf Regional Court carefully substantiated its decision," Horn commented on the outcome of the proceedings. The relevant European patent has also been validated in France, Hungary, and Spain, among other countries.
