Sitnet LLC

Sitnet LLC is identified as a non-practicing entity (NPE) and patent assertion entity (PAE) in patent litigation. It was formed by the principal of CAsE Analysis and is backed by a litigation funder. There is a separate, unrelated company named "Sitenet" (note the spelling difference) that provides IT support and telecom services in the Mercer/Bucks area, offering computer repair, network solutions, phone systems, and network security. This profile focuses on Sitnet LLC, the patent assertion entity.

Sitnet LLC asserts patents generally related to "establishment of a situational network." These patents cover technologies such as crisis communication services, targeted advertising services, and the underlying software architecture for such advertising. For example, their patents have targeted features like Facebook's Crisis Response (formerly Safety Check) and the Facebook Ad Platform.

Sitnet LLC's litigation posture is that of a patent assertion entity, primarily acting as a plaintiff in patent infringement suits. The company has been a plaintiff in one tracked case and a defendant in three cases before the Patent Trial and Appeal Board (PTAB). The PTAB cases are inter partes reviews (IPRs) initiated by Unified Patents or Meta Platforms, Inc., challenging the validity of Sitnet's asserted patents. Unified Patents is an organization dedicated to deterring frivolous patent litigation by challenging NPE patents.

Notable cases include SitNet LLC v. Meta Platforms, Inc. in the Southern District of New York, where Sitnet LLC asserted patents related to situational networks, targeting Facebook's Crisis Response and advertising features. Meta Platforms has challenged these patents through IPRs at the PTAB. A second complaint against Meta Platforms, asserting six additional patents from the same family, was filed in July 2025.
