Defendant
2 cases as defendant.
Hannibal IP LLC is a privately held patent assertion entity (PAE), also known as a Non-Practicing Entity (NPE), and an affiliate of Longhorn IP LLC ("LIP"). While its specific headquarters location is not publicly disclosed, its affiliation with Longhorn IP suggests operations within the United States. The company's primary operation is the acquisition and assertion of patent portfolios, particularly those related to 5G wireless communication technologies.
Hannibal IP LLC's core business revolves around managing and monetizing its patent portfolio, which includes patents essential to LTE and 5G standards. For instance, the company acquired a portfolio of patents related to 5G wireless technologies, including those from FG Innovation Company Ltd. These patents cover foundational technologies that have been incorporated into the 3GPP 5G Standard.
Hannibal IP LLC operates as a patent assertion entity, evidenced by its litigation posture. The provided case data shows one tracked case where Hannibal IP LLC is the defendant in a Patent Trial and Appeal Board (PTAB) proceeding. This specific case, Samsung Electronics Co Ltd et al. v. Hannibal IP LLC, is an inter partes review (IPR) initiated by Samsung against a Hannibal IP LLC patent (US11368911B2). This defensive posture at the PTAB is often seen when an operating company (like Samsung) challenges the validity of a patent asserted against it by an NPE. Public records indicate that Hannibal IP LLC previously filed a patent infringement complaint against Samsung Electronics Co., Ltd. and Samsung Electronics America in the United States District Court for the Eastern District of Texas on February 27, 2025, concerning 5G wireless communication technologies. As of December 2025, Hannibal IP LLC entered into a patent license agreement with Samsung, providing Samsung with a license to its 5G patent portfolio.
The case at the PTAB is Samsung Electronics Co Ltd et al. v. Hannibal IP LLC, initiated on July 11, 2025. This IPR proceeding targets US Patent No. 11,368,911 B2. Hannibal IP LLC's patents broadly cover methods for wireless communication, power saving signals, and handling data in wireless networks, consistent with its stated focus on 5G technologies.
An inter partes review (IPR) case filed by Samsung Electronics against Hannibal IP LLC, concerning patent 11272535, which concluded in a settlement.
An inter partes review (IPR) was filed by Unified Patents challenging US patent 11057896, with the case later reaching a settlement.
