Birchtech Corp. Files Patent Infringement Lawsuit Against Major Power Utility, Evergy

CORSICANA, Texas, Feb. 05, 2025 (GLOBE NEWSWIRE) -- Birchtech Corp., (TSX:BCHT) (OTCQB:BCHT), (“Birchtech” or the “Company”), a leader in specialty activated carbon technologies for sustainable air and water treatment, announced today that it has filed a patent infringement lawsuit in the U.S. District Court for the Western District of Missouri against Evergy, a major power utility company in the Midwest. The lawsuit filed on January 23, 2025, names four defendants and claims that the defendants knowingly violated patent rights related to Birchtech’s mercury emissions reduction technologies, commercially known as “SEA® (Sorbent Enhancement Additive) Technologies under Birchtech’s division, “ME₂C Environmental”. At Birchtech’s request, the Judicial Panel on Multi-District Litigation ordered this case transferred to the U.S. District Court for the Southern District of Iowa.

The four companies named as defendants in the lawsuit include Evergy, Inc., Evergy Metro Inc., Evergy Missouri West, Inc., and Evergy Kansas Central, Inc., for patent infringement. The Company requests a trial by jury against the defendants and seeks damages, costs, and legal expenses, along with a finding of willful infringement by the defendants, and an injunction prohibiting the defendants from further acts of infringement.

“Following our successful jury trial in 2024, we will continue these efforts to protect our patented technologies in support of our company’s growth and to benefit our shareholders,” stated Richard MacPherson, CEO of Birchtech Corp. “Since our litigation efforts commenced in 2019, our primary objective has been to enter into positive, mutually beneficial business relationships across the industry and have been successful with several of our previous defendants reaching license and/or supply agreements for the continued use of our highly efficient, effective technologies for mercury emissions capture.  

“With a recently named defendant in one of the July 2024 lawsuits, we have entered into the product testing phase at the utility, which is typically the first step toward transitioning the utility to ME₂C’s supply. We expect to move forward similarly with other defendants and other utilities in the industry who may be using our patented technologies separate from our company.

“Our focus in 2025 is to protect the validity of our patents in clean air technologies, laying the foundation for our strategic growth in highly innovative water purification technologies currently under development,” concluded MacPherson.

Prior to this lawsuit announced today, the Company achieved a successful outcome in a five-year patent infringement lawsuit initiated in 2019 against 43 defendants that included four major power utilities and numerous refined coal companies. In late 2023, Birchtech obtained a pre-trial settlement with defendants AJ Gallagher, DTE, and a CERT Defendant. In March 2024, following trial in the U.S. District Court of Delaware with the remaining CERT Defendants, the Company was awarded a $57 million verdict following a jury trial with a unanimous finding of willful infringement, along with inducing and contributory infringement. In July 2024, the Company filed three separate lawsuits against a total of 14 defendants, which included major coal-fired utilities, in U.S. District Courts in Arizona, Iowa, and Missouri. In December 2024, the three separate lawsuits were consolidated and centralized in the Southern District of Iowa.
