BIRCHTECH SECURES LICENSE AGREEMENT WITH LARGE REGIONAL UTILITY

Birchtech Corp. has entered a non-exclusive licensing agreement with a large regional coal-fired utility for the licensing of the company's patented mercury emissions reduction technologies.

The licence agreement includes a one-time fee, though due to confidentiality agreements and continuing litigation, other specific terms of the agreement cannot be publicly disclosed. Although not named as a defendant in the company's various patent litigations, this utility is a party to the petitions filed with the United States Patent and Trademark Office requesting inter partes review. With the licence agreement in place, this utility has agreed to withdraw from petitions for inter partes review.

Richard MacPherson, Birchtech chief executive officer, commented: "Our outreach across the industry has been well received, reflecting our 'business-first' approach that continues with other utilities. Our patented technologies for mercury emissions provide utilities with a more affordable, effective solution, which becomes more important for grid reliability as energy demands increase.

"Since 2019, we have now successfully reached 14 licence agreements with coal-fired utilities, including nine utilities previously named as defendants in the 2019 or 2024/2025 lawsuit filings. With ongoing posttrial outreach aiming to convert technology users to customers, our air business is further powering the ramp of our new comprehensive water treatment solutions and providing sustainable, long-term value for our shareholders," concluded Mr. MacPherson.
