CERT Operations IV LLC operates as a Non-Practicing Entity (NPE), also commonly referred to as a Patent Assertion Entity (PAE). These entities typically acquire patents from third parties and seek to generate revenue primarily through patent licensing negotiations or litigation, rather than by manufacturing or selling products or services. This distinguishes them from operating companies that utilize patents to protect their own innovations and products.

According to the authoritative case data, the company has been involved in a total of two tracked cases: one as a plaintiff and one as a defendant. These cases have been litigated in the U.S. District Court for the District of Delaware and the Court of Appeals for the Federal Circuit.

Notable cases include CERT Operations II LLC et al. v. Birchtech Corp., where CERT Operations IV LLC appeared as a plaintiff in the Court of Appeals for the Federal Circuit in 2026. Conversely, the company was a defendant in 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.
