Headwater Research LLC

Headwater Research LLC is a private technology development and patent assertion entity headquartered in Tyler, Texas. While legal filings state it was formed in 2011, other sources place its founding in 2008. The firm was founded by Dr. Greg Raleigh, an inventor in the wireless communication field who is the source of the patents the company asserts. Headwater's website states that it invents and develops "significant technological breakthroughs," but it is primarily known as a non-practicing entity (NPE) that monetizes its intellectual property through litigation and licensing campaigns.

The company controls a large patent portfolio, with some families containing nearly 280 patents, generally related to mobile device technology. The patents cover wireless communications, mobile device operating systems, data management, network optimization, and power consumption. Based on available court records, Headwater acts exclusively as a plaintiff in patent litigation, suing operating companies for alleged infringement. This is consistent with its 100% plaintiff record in the tracked cases (four plaintiff cases, zero as a defendant). The company frequently files its lawsuits in the U.S. District Courts for the Eastern and Western Districts of Texas, venues known for patent litigation.

Headwater has engaged in numerous high-profile patent infringement lawsuits against major telecommunications and technology companies. The provided case data lists suits against Verizon, T-Mobile, AT&T, and Apple. Beyond these cases, Headwater has also litigated extensively against other major tech companies, including Samsung and Google. The company has secured significant jury verdicts, including a $278.8 million award against Samsung in April 2025 and a $175 million award against Verizon in July 2025. It has reportedly reached settlements with Apple, AT&T, and T-Mobile.
