Case Background
Headwater Research LLC, a Texas limited liability company headquartered in Tyler, Texas, brought this patent infringement lawsuit against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the United States District Court for the Eastern District of Texas, Marshall Division. Judge Rodney Gilstrap presided over the case.
The dispute centered on wireless communications technology developed by Dr. Gregory Raleigh, the primary inventor of the patents-in-suit and the founder of both Headwater and ItsOn Inc. Dr. Raleigh, who holds a Ph.D. in Electrical Engineering from Stanford University, is the inventor of over 350 issued U.S. and international patents across multiple technology fields. In 2008, Dr. Raleigh founded ItsOn Inc., which licensed Headwater's intellectual property and implemented the patented technology into software and services for cellular carriers and device manufacturers.
Between 2013 and 2016, ItsOn worked with Sprint and Samsung under non-disclosure agreements to integrate Headwater's patented technology directly into Samsung devices. Sprint mandated that Android handset manufacturers, including Samsung, integrate ItsOn's software into device operating systems and kernels. More than a dozen Samsung device models were enabled with ItsOn solutions, and by the end of 2015, millions of Sprint devices — including Samsung devices — ran the ItsOn application.
According to the complaint, in early October 2015, Sprint personnel informed ItsOn that Samsung planned to implement the patented technology in its own device software without further involvement from ItsOn. On October 9, 2015, Samsung's U.S. subsidiary announced that Samsung Korea would take over negotiations with ItsOn. Shortly after, Samsung Korea ended the ItsOn implementation project. On October 27, 2015, Sprint purported to terminate its master service agreement with ItsOn. Headwater alleged that Samsung subsequently released new devices incorporating features and functionalities that infringed Headwater's patents.
Samsung Display Co., Ltd. was initially named as a Defendant but was dismissed from the action prior to Samsung's answer.
Cause
Headwater filed its First Amended Complaint on July 24, 2023, alleging infringement of three United States patents: U.S. Patent No. 8,406,733 (the '733 Patent), titled "Automated device provisioning and activation," issued March 26, 2013; U.S. Patent No. 9,198,117 (the '117 Patent), titled "Network system with common secure wireless message service serving multiple applications on multiple wireless devices," issued November 24, 2015; and U.S. Patent No. 9,615,192 (the '192 Patent), titled "Message link server with plural message delivery triggers," issued April 4, 2017.
At trial, Headwater asserted Claims 1, 7, and 19 of the '733 Patent and Claims 1, 12, and 16 of the '117 Patent. The '192 Patent was not part of the jury verdict form.
The accused products included Samsung's Galaxy phones and tablets, devices with Samsung Knox functionality, and Samsung Tizen-based devices such as televisions and wearables.
Injury
Headwater alleged that Samsung directly infringed and induced others to infringe the '733 and '117 Patents by making, using, selling, offering for sale, and importing the accused devices in the United States without a license or permission from Headwater.
Damages Sought
Headwater sought reasonable royalty damages under 35 U.S.C. § 284, along with pre-judgment and post-judgment interest. Headwater initially alleged willful infringement and sought enhanced damages but withdrew all willfulness allegations prior to trial.

Key Arguments or Remarks by Counsel
Headwater argued that Samsung gained direct knowledge of the patented technology through its working relationship with ItsOn and Sprint between 2013 and 2016. ItsOn software implementing Headwater's patented inventions was installed on numerous Samsung devices sold by Sprint. Headwater's patents were disclosed to Samsung in various meetings and through various presentations during that collaboration. ItsOn and Samsung held frequent, in-depth meetings to discuss engineering details and implement ItsOn's solutions into Samsung's software builds. ItsOn installed its confidential and proprietary software onto Samsung devices, granting Samsung executives and engineering teams root and debug access under NDA for testing and implementation.
Claims
Headwater asserted that Samsung infringed Claims 1, 7, and 19 of the '733 Patent and Claims 1, 12, and 16 of the '117 Patent through its accused Galaxy phones and tablets, devices with Knox functionality, and Tizen-based devices.
Defense
Samsung denied all allegations of infringement and asserted that the asserted patent claims were invalid under 35 U.S.C. §§ 101, 102, 103, and 112. Samsung raised defenses of laches, equitable estoppel, waiver, unclean hands, prosecution history estoppel, disclaimer, inequitable conduct, infectious unenforceability, prosecution laches, failure to state a claim, no standing, and a covenant not to sue or license defense.
Samsung argued that the patent applicants committed inequitable conduct by knowingly failing to disclose material prior art related to the Android operating system to the U.S. Patent and Trademark Office during patent prosecution. Samsung contended that named inventor Gregory Raleigh and prosecuting attorney James Harris were aware of the Android OS and its related documentation before and during prosecution of the patent applications, recognized it as material prior art, yet chose not to disclose it. Samsung also argued that Headwater delayed prosecution of its patents for years after filing its earliest provisional application in January 2009, constituting prosecution laches.
Prior to trial, Samsung stipulated that none of its previously raised invalidity and equitable defenses remained live as post-trial issues for the Court to decide.
Jury Verdict
A jury trial commenced on April 21, 2025. On April 25, 2025, the jury returned a unanimous verdict in favor of Headwater.
The jury found that Samsung infringed Claims 1, 7, and 19 of the '733 Patent and Claims 1, 12, and 16 of the '117 Patent. The jury also found that Samsung failed to prove by clear and convincing evidence that any of the asserted claims were invalid. The jury awarded Headwater $278,791,460.00 as a lump sum reasonable royalty for Samsung's infringement.
On May 30, 2025, the Court entered Final Judgment based on the jury's unanimous verdict and Samsung's stipulations. The Court awarded pre-judgment interest at the 5-year U.S. Treasury Bill rate, compounded quarterly, from the date of infringement through the date of judgment. The Court awarded post-judgment interest at the statutory rate from the date of judgment until paid. The Court declared Headwater the prevailing party and directed Headwater to file its Bill of Costs. The Court dismissed all willfulness claims, which Headwater had withdrawn prior to trial, and dismissed all of Samsung's equitable defenses, which Samsung had stipulated were no longer live issues. All other pending requests for relief were denied.
