Case Overview
The Parties
⚖️ Plaintiff
Entities associated with the Uniloc patent licensing group, a prolific patent assertion entity (PAE) known for pursuing licensing revenue through high-volume litigation across technology sectors.
🛡️ Defendant
Global technology leader whose product ecosystem — spanning mobile devices, cloud computing, and communication applications — makes it a frequent target in patent litigation. A subsidiary of Alphabet Inc.
Patents at Issue
This case involved three U.S. patents asserted against a broad range of Google’s communication technologies. These patents broadly cover voice and data communication technologies, representing the type of foundational IP often asserted against platform-level products.
- • US7853000B2 — Relates to telephony communication systems
- • US7804948B2 — Covers communication signal processing technology
- • US8571194B2 — Directed to communication infrastructure methods

The Verdict & Legal Analysis
Outcome
The case was resolved through an FRCP 41(a)(1)(A)(i) Joint Stipulation of Dismissal, filed jointly by both parties. Plaintiff’s claims against Google were dismissed with prejudice — meaning Uniloc cannot reassert these specific infringement claims against Google on these patents in future litigation. Google’s counterclaims and defenses were dismissed without prejudice, preserving Google’s ability to raise invalidity or other challenges in different proceedings if necessary.
Key Legal Issues
The dismissal with prejudice on the plaintiff’s side is the analytically significant element. Several factors may have shaped this outcome: Inter Partes Review (IPR) exposure, as Uniloc’s patent portfolio has faced substantial USPTO validity challenges; Post-TC Heartland pressure, which significantly altered where patent cases could be filed and sustained; and the breadth of accused products, which multiplied the evidentiary burden Uniloc faced in proving infringement across diverse product architectures.

Three U.S. patents: US7853000B2, US7804948B2, and US8571194B2, covering telephony and communication technologies.
The parties filed a joint stipulation under FRCP 41(a)(1)(A)(i). Plaintiff’s claims were dismissed with prejudice, meaning Uniloc cannot reassert these specific infringement claims against Google on these patents in future litigation. Google’s counterclaims were dismissed without prejudice.
It reinforces that well-resourced defendants like Google can sustain multi-year litigation campaigns against Patent Assertion Entities (PAEs), often achieving resolution without public adverse verdicts. It also highlights the strategic importance of preserving invalidity options through counterclaim preservation.
Communication software (VoIP, messaging applications) integrated into hardware platforms carries layered patent risk requiring both device-level and application-layer FTO analysis. Chromebook and Android device categories remain active targets, emphasizing the need for robust IP clearance before product launch.
