Vannisi

Based on available information, Vannisi is not an operating company but rather the name associated with a patent plaintiff. Web searches do not identify a corporate entity, website, or business operations under this name, suggesting "Vannisi" is likely the name of an individual inventor. No information regarding headquarters, founding date, or employee count is publicly available.

Vannisi has no known products, services, or other business operations. The entity's only known activity is patent litigation. As a non-practicing entity (NPE), or patent assertion entity (PAE), it generates revenue by licensing or litigating patents rather than by producing goods or services. The specific patents asserted by Vannisi could not be identified through public searches.

The entity's litigation posture is that of a patent enforcer. The provided database shows Vannisi involved in one case as a plaintiff and in no cases as a defendant. An entity that exclusively initiates patent lawsuits without being a defendant in such suits is characteristic of an NPE.

The single tracked case is Vannisi et al. v. LiPang et al., an appeal filed at the U.S. Court of Appeals for the Federal Circuit in April 2026. An appearance at the Federal Circuit indicates that this case is an appeal of a final decision from a U.S. District Court or the Patent Trial and Appeal Board. The "et al." in the case name indicates multiple plaintiffs and defendants were involved in the original dispute.
