Senescence Energy Products, LLC is a private company that has been identified as one of the "CERT RC Defendants" in patent litigation. The company's headquarters and founding date are not publicly available. There is no public information on its size in terms of employee count or revenue.

The specific products or services offered by Senescence Energy Products, LLC are not detailed in public records, but its involvement in litigation suggests a connection to the refined coal industry and mercury emission reduction technologies. The company was a defendant in a patent infringement lawsuit regarding mercury-capture technology used in coal-fired power plants.

Senescence Energy Products, LLC appears to be an operating company that has defended against patent infringement claims. It was a defendant in the case Midwest Energy Emissions Corp. et al. v. CERT Operations II LLC et al., filed in the U.S. District Court for the District of Delaware in 2019. The company was also listed as a plaintiff in CERT Operations II LLC et al. v. Birchtech Corp. at the Court of Appeals for the Federal Circuit in 2026, indicating an active role in patent disputes.

In the Midwest Energy Emissions Corp. case, Senescence Energy Products, LLC, along with other "CERT Defendants," was found by a jury in March 2024 to have infringed on two patents related to mercury-capture technology and was liable for over $57 million in damages. The lawsuit alleged that the defendants reaped "staggering profits" from federal tax credits by using the patented technology to reduce mercury emissions from coal-fired power plants. In December 2025, the judgment amount was increased to approximately $78 million, including pre-judgment interest.
