Complaint alleges Apple's 5G-enabled iPhones and iPads infringe multiple patents critical to next-generation wireless communications
PLANO, Texas, August 28, 2026 – Hannibal IP LLC, a Longhorn IP Affiliate, has filed a patent infringement lawsuit against Apple Inc. in the United States District Court for the Western District of Texas, asserting a portfolio of patents directed to foundational 5G wireless technologies. The case number is 7:26-cv-00341.
The complaint alleges that Apple's 5G-enabled iPhone and iPad products infringe six U.S. patents owned by Hannibal IP covering advanced 5G functionalities adopted within the 3GPP wireless communications standards. According to the complaint, the asserted patents address critical technologies including beam management, quasi co-location (QCL) assumptions, multi-transmit/receive point (multi-TRP) operations, uplink transmission procedures, and Listen-Before-Talk (LBT) failure detection mechanisms.
The lawsuit targets Apple's 5G smartphone and tablet product lines, including 5G-capable iPhones introduced beginning with the iPhone 12 and 5G-capable cellular iPads. The complaint further alleges that Apple utilizes both Qualcomm modem technology and Apple's own modem technology in accused products while continuing to implement the patented 5G functionalities.
"5G innovation depends on the contributions of technology developers whose inventions become embedded in global industry standards," said Hannibal IP. "This case seeks fair compensation for Apple's use of technologies that Hannibal believes are fundamental to the operation of modern 5G devices." Hannibal asserts the following U.S. patents:
U.S. Patent No. 11,057,896
U.S. Patent No. 11,641,661
U.S. Patent No. 11,272,535
U.S. Patent No. 11,683,142
U.S. Patent No. 10,911,201
U.S. Patent No. 12,108,412
The complaint alleges that the asserted inventions have been incorporated into the 3GPP 5G standard and that Apple products implementing the standard practice the patented technologies. Hannibal further alleges that Apple has been aware of the asserted patent portfolio and infringement contentions for years, yet continued its allegedly infringing activities. The lawsuit seeks damages for past infringement, enhanced damages for alleged willful infringement, attorneys' fees, ongoing royalties, and other relief deemed appropriate by the Court.
The filing also states that Hannibal owns numerous patents originally assigned to FG Innovation Company Limited that are essential to practicing the 3GPP 5G standard and that Hannibal has informed Apple of its willingness to license its standard-essential patents on FRAND terms. The complaint alleges that Hannibal has engaged with Apple over several years and has complied with its FRAND obligations.
The action underscores the continuing importance of standard-essential patents in the global wireless ecosystem and highlights the obligation of device manufacturers to appropriately compensate innovators whose technologies make advanced wireless communications possible. Hannibal believes that strong intellectual property protections remain essential to driving future investment and innovation in next-generation communications technologies.
