PITTSBURGH – A Pittsburgh chemical company is suing a competitor alleging that it infringed on a mine drainage patent.

Kroff Chemical Co. Inc. filed a lawsuit Jan. 20 in the U.S. District Court for the Western District of Pennsylvania against Enviromine Inc., alleging patent infringement.

According to the lawsuit, Kroff is owner of the '201 patent, titled Method of Treating Mine Drainage, which was issued by the U.S. Patent and Trademark Office on Oct. 3, 2006. According to the lawsuit, Enviromine is manufacturing, selling using a scale control agent sold and marketed under the trade name CF-36X, which, according to the lawsuit, is an infringement of Kroff’s trademark.

Kroff is seeking that Enviromine pay damages, including interest from the dates of infringement, as well as reasonable attorney fees. It is represented by attorney Kent E. Baldauf Jr. and Bryan P. Clark of the Webb Law Firm in Pittsburgh.
