Litigation and corporate finance analyst

Birchtech wins a final patent judgment awarding about $78.4M in damages.

Birchtech Corp. obtained a final judgment from the U.S. District Court for the District of Delaware on December 29, 2025 in its patent infringement case against the remaining CERT defendants. The court awarded damages of $78,397,157.05, which includes pre-judgment interest, following a jury verdict returned on March 1, 2024 in Birchtech’s favor.

The court denied the CERT defendants’ post-trial motions related to implied license and infringement liability, leaving the liability findings intact. It granted Birchtech’s request for pre- and post-judgment interest but denied its request for enhanced damages, so the award remains at the jury-determined level plus interest rather than a higher, punitive amount.

This outcome provides a quantified damages figure and confirms a favorable final judgment at the trial-court level. Actual cash impact will depend on enforcement and any appeal processes, which are not described in this disclosure, so future company communications and filings would clarify if and when the awarded amount is realized.
