Company profile

CERT Operations II LLC is a privately held limited liability company primarily engaged in patent assertion and licensing. While its specific founding date is not publicly available, a related entity, CERT Operations RCB, LLC, was registered in Delaware in 2014 with a principal address in Birmingham, Alabama, suggesting a potential similar operational base or registration for CERT Operations II LLC. No information regarding the company's employee count, revenue, or specific products or services is publicly disclosed, a characteristic often associated with non-practicing entities (NPEs) or patent assertion entities (PAEs).

As a non-practicing entity, CERT Operations II LLC does not produce products or offer services based on its patents. Instead, its business model centers on acquiring patents and generating revenue through their assertion and licensing against alleged infringers. Such entities are often referred to as "patent trolls" due to their focus on patent monetization rather than commercializing patented technology.

CERT Operations II LLC maintains an active posture in patent litigation, appearing in tracked cases both as a plaintiff and a defendant. The company is involved as a plaintiff in CERT Operations II LLC et al. v. Birchtech Corp. before the Court of Appeals for the Federal Circuit (2026). Conversely, it is 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 (2019). This mixed litigation role indicates that the entity both asserts patents and may defend against related challenges or counterclaims.

The company appears to be part of a broader network of similarly named LLCs, including CERT Operations, LLC, CERT Operations III, LLC, CERT Operations IV, LLC, CERT Operations V, LLC, and CERT Operations RCB, LLC, which frequently appear together in patent litigation dockets. This structure is often utilized by patent assertion entities to manage and assert various patent portfolios.
