Stingray IP Solutions LLC is a non-practicing entity (NPE) and a subsidiary of Acacia Research Corporation, focusing on monetizing intellectual property through patent assertions. Information regarding its specific headquarters or founding year is not publicly available, beyond its affiliation with Acacia Research, a publicly traded company.
As an NPE, Stingray IP Solutions LLC does not offer products or services. Instead, it asserts a portfolio of acquired patents, primarily related to wireless networking, including secure wireless LAN (Local Area Network), intrusion detection, and mobile ad hoc networks (MANET) technologies. These patents cover aspects like encrypting address and data information in wireless LAN devices, detecting intrusions in network systems, and channel allocation in mobile ad hoc networks.
Stingray IP Solutions LLC is an active patent litigant, exclusively as a plaintiff in all 7 tracked cases. The majority of its lawsuits have been filed in the Eastern District of Texas, a venue known for patent litigation. This litigation posture, combined with its lack of operational products, firmly characterizes it as a patent assertion entity.
Notable cases include those against Amazon.com Inc., TP-Link Corporation Ltd., Signify Netherlands BV, Assa Abloy IP AB, Bticino SPA, and Somfy Activits SA. Stingray IP Solutions has also asserted patents against companies like Hewlett Packard Enterprise, Leedarson IoT, Schlage Lock, Vivint, Allegion, and ADT Inc., often targeting their smart home, networking, and security products that utilize Wi-Fi and Zigbee protocols. In some instances, such as a case against Snap One, cases have concluded with a joint dismissal with prejudice, suggesting negotiated settlements. Furthermore, Unified Patents has successfully challenged some of Stingray IP's asserted patents, leading to notices of intent to issue reexamination certificates canceling claims, such as U.S. Patent 7,224,678.
