Case Overview
The Parties
⚖️ Plaintiff
A patent licensing and assertion entity with a portfolio focused on wireless communication, mobile device management, and network optimization technologies.
🛡️ Defendants
Included T-Mobile USA, Sprint, Verizon, AT&T, Ericsson, and Nokia, representing major U.S. wireless carriers and dominant global network equipment suppliers.
The Patents at Issue
Two U.S. patents formed the basis of the infringement claims, directed at wireless network communication technology. Both fall within the domain of cellular network infrastructure, relevant to modern 4G LTE and 5G deployments.
- • US9413502B2 — Directed to wireless network communication technology
- • US9094868B2 — Covering related wireless transmission architecture

The Verdict & Legal Analysis
Outcome
The case resolved through a **Joint Stipulation of Dismissal** on January 28, 2026. Headwater’s claims were dismissed **WITH PREJUDICE**, meaning they cannot re-file these same infringement claims against these defendants on these patents. Defendants’ counterclaims (e.g., invalidity challenges) were dismissed **WITHOUT PREJUDICE**, preserving their right to re-raise them if needed. Specific financial terms were not publicly disclosed.
Key Legal Issues
Because the case resolved through stipulated dismissal, **no formal findings on patent validity, infringement, or claim construction were issued by the court**. This means no binding legal precedent emerged directly from this proceeding on the substantive patent questions. The asymmetric dismissal structure indicates a comprehensive licensing resolution or a strategic decision to abandon assertion against these specific defendants.

The case involved U.S. Patent Nos. US9413502B2 and US9094868B2, both directed to wireless network communication technologies relevant to 4G LTE and 5G base station infrastructure.
The parties filed a Joint Stipulation of Dismissal under Rule 41(a)(1)(A)(ii). Headwater’s infringement claims were dismissed with prejudice; defendants’ counterclaims were dismissed without prejudice, indicating a privately negotiated resolution.
It reinforces that multi-defendant wireless infrastructure assertions frequently resolve through licensing rather than adjudication, and that defendants benefit from coordinated defense and preserved IPR options.
