SITNETLLC

SITNETLLC is a Non-Practicing Entity (NPE) that generates revenue primarily through patent assertion and licensing. It operates without developing or offering its own products or services. The entity was formed by the principal of CAsE Analysis and is supported by a litigation funder, a common characteristic among patent assertion firms. Due to its nature as an NPE, specific details regarding its headquarters, founding year, employee count, or revenue are not publicly available.

SITNETLLC asserts a portfolio of patents generally related to social networking technologies. These include innovations in crisis communications services, targeted advertisement services, and the underlying software architecture for such advertising. Its patent assertion campaigns aim to monetize these intellectual property rights through litigation or licensing agreements.

The company's litigation posture is that of an NPE actively asserting its patent portfolio. It has a track record of initiating patent infringement lawsuits, as evidenced by its single plaintiff case. Conversely, it has appeared as a defendant in a single case, which is a defensive action, likely an Inter Partes Review (IPR) challenging the validity of its patents.

Notably, SITNETLLC initiated litigation against Meta Platforms, Inc. in 2025 in the United States District Court for the Southern District of New York, asserting patents related to social networking technologies. The asserted patents specifically targeted Facebook functions, including the Facebook Safety Check/Crisis Response feature and Facebook Ad Platform/Meta's Marketing API. In response, Meta Platforms, Inc. filed a defensive action against SITNETLLC in 2026 at the Patent Trial and Appeal Board (PTAB), challenging the validity of the patents being asserted.
