CERT Operations RCB LLC is a privately held limited liability company, registered in Delaware on January 27, 2014, with a principal address in Birmingham, Alabama. It is part of a group of affiliated entities, including CERT Operations II LLC, CERT Operations IV LLC, and CERT Operations V LLC, primarily involved in refined coal industry operations. Information regarding employee count or specific revenue figures for CERT Operations RCB LLC is not publicly available.
The company's operations are centered around the refined coal industry, as evidenced by its involvement in patent litigation concerning mercury-capture technology. Rather than asserting patents, CERT Operations RCB LLC and its affiliates function as operating companies whose business activities have led to patent infringement claims.
CERT Operations RCB LLC's patent litigation posture is primarily defensive. Of its two tracked cases, one is as a defendant and the other, while listed as plaintiff, represents an appeal of an adverse judgment. The company has been defending against allegations of patent infringement, predominantly in the U.S. District Court for the District of Delaware.
The most notable case is Midwest Energy Emissions Corp. et al. v. CERT Operations II LLC et al., filed in 2019, where CERT Operations RCB LLC and other CERT entities were found liable for infringing patents related to mercury-capture technology used in coal-burning power plants. A federal jury in Delaware awarded Midwest Energy Emissions Corp. (now Birchtech Corp.) $57 million, with CERT Operations RCB LLC reportedly liable for over $35 million of that amount. With pre-judgment interest, the total judgment against the CERT defendants increased to approximately $78 million. The currently tracked plaintiff case, CERT Operations II LLC et al. v. Birchtech Corp., filed in January 2026 at the Court of Appeals for the Federal Circuit, represents CERT's appeal of this judgment, with Birchtech actively pursuing enforcement. Additionally, in March 2026, CERT Operations RCB, LLC was named as a defendant in a new patent infringement lawsuit, Bromerc Ltd. et al v. CERT Operations, LLC et al, filed in the U.S. District Court for the District of Delaware.
