Springhill Resources, LLC is a privately held entity primarily known through its involvement in patent litigation. Public records indicate a "SPRING HILL RESOURCES, LLC" (note: "Spring Hill" vs. "Springhill") registered in Florida, though its status is listed as inactive. Efforts to identify a definitive headquarters, year of founding, or employee/revenue figures for an active operating company under this precise name through public web searches were not conclusive.
The company's operational profile, beyond its role in legal proceedings, is not publicly detailed. It does not appear to actively market specific products or services. Its involvement in patent litigation, particularly as a defendant in a case related to mercury emission control technology, suggests its activities may be related to intellectual property licensing or enforcement within that technology domain, or as a holding entity within a larger group.
Springhill Resources, LLC demonstrates a mixed patent litigation posture, having appeared as both a plaintiff and a defendant in tracked cases. It has been a plaintiff in one case and a defendant in one case. The company was a defendant in Midwest Energy Emissions Corp. et al. v. CERT Operations II LLC et al. in the U.S. District Court for the District of Delaware, a venue known for patent disputes.
Notably, Springhill Resources, LLC was among several entities, including CERT Operations II LLC, found liable for indirect and willful infringement of patents related to mercury emission control technologies for coal-fired power plants. The jury in that case awarded damages exceeding $57 million. Springhill Resources, LLC is also listed as a plaintiff (alongside CERT Operations II LLC) in the more recent CERT Operations II LLC et al. v. Birchtech Corp. case before the Court of Appeals for the Federal Circuit. This dual role and its consistent association with "CERT Operations II LLC" in litigation suggest it may be part of a group of entities involved in intellectual property assertion and defense in the energy sector.
