Company profile

Piney Woods Mobility LLC is a Florida-based limited liability company, registered in August 2015. Its principal address is in Tampa, Florida, and its manager is Florida Longhorn LLC. The company does not appear to offer any commercial products or services, operating instead as a non-practicing entity (NPE).

Piney Woods Mobility LLC's operations are centered on asserting a patent portfolio related to location-sharing and position-sharing technologies. The asserted patents, including U.S. Patent Nos. 8,712,441, 9,031,581, 9,185,522, 9,253,616, 9,615,204, and 9,736,618, broadly cover methods and systems for sharing position data between mobile devices and transmitting content based on proximity.

The company exhibits a clear patent assertion litigation posture, acting as a plaintiff in 12 out of its 13 tracked cases. The sole defendant case, filed by Apple, Inc., is likely a declaratory judgment action. Piney Woods Mobility LLC has primarily filed lawsuits in U.S. District Courts for the Eastern and Western Districts of Texas, venues frequently utilized by patent plaintiffs.

Notable recent cases include multiple lawsuits filed in February 2026 against prominent technology and telecommunications companies such as Apple Inc., Samsung Electronics, T-Mobile USA, Inc., AT&T Inc. et al., and Verizon Communications, Inc. These cases allege infringement related to location-sharing services and programs like Verizon Family, T-Mobile Family Mode, AT&T Secure Family, and Samsung's SmartThings.
