But that July 2025 damages verdict was followed by a major development: in April 2026, a judge ruled that Headwater could not enforce the asserted patents against Verizon because of implied waiver. The award was damages, not a government fine, and the available opinion does not establish whether the case has since been appealed or whether Verizon paid anything.
What happened in the Verizon–Headwater case?
Headwater Research LLC sued Cellco Partnership, doing business as Verizon Wireless, and Verizon Corporate Services Group, Inc., in the U.S. District Court for the Eastern District of Texas, Marshall Division. The case, Headwater Research LLC v. Verizon Communications Inc. et al., No. 2:23-CV-00352-JRG-RSP, was filed on July 28, 2023. The court’s April 22, 2026 memorandum opinion and order describes the two asserted patents as covering background-data technologies.
The case produced two different rulings. A jury found willful infringement and awarded Headwater $175 million in damages on July 23, 2025. After a separate bench trial on Verizon’s equitable defenses, the judge ruled on April 22, 2026, that Headwater could not enforce the asserted patents against Verizon. The later ruling substantially undercuts the practical effect of the jury award, but the opinion alone does not establish the award’s ultimate procedural status.
What patents and technology were involved?
The asserted patents were U.S. Patent Nos. 8,589,541 and 9,215,613. The court characterized them as relating to background-data technologies. That description does not establish that the patents broadly cover smartphone connectivity, battery savings, or any specific Verizon service or device.

What did the jury decide?
On July 23, 2025, the jury found that Verizon willfully infringed the asserted patents and awarded Headwater $175 million. This was a civil patent-infringement damages award, not a regulatory penalty or criminal fine. The available opinion does not provide a damages breakdown, royalty rate, accused products or services, or detailed infringement findings for each patent.
Why was there a second trial?
Verizon raised equitable defenses, including equitable estoppel and waiver. The judge—not the jury—heard those issues at a bench trial on February 4, 2026. The court rejected Verizon’s arguments based solely on its investment history with Headwater and ItsOn, but accepted a separate implied-waiver argument tied to Headwater’s conduct after it began investigating possible infringement.
How did Verizon’s investment relationship matter?
The court found that Verizon invested $1.75 million in Headwater for a 10% equity interest in 2010, then invested more than $30 million in ItsOn between 2015 and 2017. Although Headwater and ItsOn were distinct companies, the court treated them as functionally one entity for purposes of the bench trial because of their coordination and common control by Dr. Gregory Raleigh. Verizon still held an equity interest in Headwater when the April 2026 opinion was issued.
The investments provided context for the dispute but did not automatically give Verizon permission to practice Headwater’s patents. The court declined to create an “investor shop right,” and it rejected equitable relief based only on the investments.

Why did the judge find implied waiver?
Implied waiver is not simply a rule that a patent owner loses rights by waiting to sue. The court asked whether Headwater’s conduct was so inconsistent with later enforcement that it reasonably led Verizon to believe the relevant rights had been relinquished. It also considered whether Verizon was prejudiced by that conduct.
The judge rejected Headwater principal Gregory Raleigh’s testimony that Headwater lacked enough information to bring an infringement claim until 2023. Instead, the court found that Headwater began investigating possible Verizon infringement in 2017 and had enough knowledge then to bring a claim. Headwater filed suit in July 2023. The court found that the delay was attributable to maximizing potential damages within the six-year statutory period.
The parties agreed Verizon did not know about the asserted patents until Headwater filed suit. The judge concluded that Verizon reasonably could have believed Headwater would not enforce patents it already knew Verizon was infringing. The court also found prejudice: the delay deprived Verizon of an earlier opportunity to seek non-infringing alternatives. On that basis, it held that Headwater could not enforce the asserted patents against Verizon.
The opinion distinguished implied waiver from laches and said the Supreme Court’s decision in SCA Hygiene Products Aktiebolag v. First Quality Baby Products did not foreclose equitable relief addressing liability under implied waiver.

Does Verizon have to pay the $175 million?
The jury awarded $175 million, but the later opinion held that Headwater cannot enforce the asserted patents against Verizon. That ruling appears to prevent Headwater from collecting on the jury’s damages verdict, subject to any subsequent judgment or appeal. The available opinion does not establish whether the award was formally vacated, whether Verizon paid any amount, or whether either party appealed. Those questions require the later docket record; it would be inaccurate to state from this opinion alone that Verizon definitely owes or definitely paid nothing.
Does the ruling affect Verizon customers?
No verified customer-facing consequence is established by the court opinion. It does not report a Verizon surcharge, plan-price change, network shutdown, device recall, or service change. The dispute concerns patent enforcement and corporate liability, and any claim that customers will pay more would be speculation without supporting evidence.
Quick Recap
What the ruling may mean for patent disputes
- Delay can create equitable risk. The court’s ruling turned on its findings about what Headwater knew, when it knew it, and how the delay affected Verizon—not on elapsed time alone.
- Commercial ties can shape the facts. Verizon’s investments became relevant context, but they did not themselves create a patent license.
- A jury verdict may not end a case. Equitable defenses decided later by a judge can materially change the practical consequences of a damages verdict.
