Semantic Engines LLC

Semantic Engines LLC is a privately held technology company based in New York that conducts research and development in fields including information retrieval, text mining, semantic analysis, and contextual advertising. The company's website describes applications such as "SenseBot," a search engine that summarizes multiple web pages, and tools for analyzing web sentiment. The size of the company, including its employee count and revenue, could not be verified from public sources.

The company's primary business appears to be technology development and patent licensing. Its main offerings, as described on its website, are focused on vertical-specific applications for its search and analysis technology in areas like finance, competitive intelligence, and social media. It is unclear from publicly available information whether these applications are commercial products with a customer base or research and development projects.

Semantic Engines LLC is active in patent litigation. As of May 2026, the company has one tracked patent infringement lawsuit, which it filed as a plaintiff. This litigation pattern, with no record of being a defendant, is often characteristic of a non-practicing entity (NPE) or patent assertion entity. The single lawsuit was filed in the Eastern District of Texas, a venue known for patent cases.

The company's notable litigation is the case Semantic Engines LLC v. Microsoft Corp, filed in April 2026. In the suit, Semantic Engines alleges that Microsoft's Copilot artificial intelligence assistant infringes on three of its patents related to multi-document search technology. According to reports, the patents-in-suit date back to a 2007 patent application, and the company's founder, Dmitri Soubbotin, had previously contacted Microsoft regarding the technology.
