🛡️ Defendant
One of the largest telecommunications carriers in the U.S., operating extensive 4G LTE and 5G networks.
The Patents at Issue
This litigation involved two United States patents covering technologies implicated in 4G LTE and 5G base stations, network nodes, and related telecommunications equipment and services.
- • US9413502B2 — directed to wireless network communication technology
- • US9094868B2 — directed to related wireless infrastructure technology

The Verdict & Legal Analysis
Outcome
The case concluded via a Joint Stipulation of Dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). All of Plaintiff’s claims were DISMISSED WITH PREJUDICE, while all of Defendants’ counterclaims were DISMISSED WITHOUT PREJUDICE. This asymmetric dismissal strongly suggests a confidential licensing agreement or settlement payment was reached.
Key Legal Issues
This case, filed in the Eastern District of Texas and presided over by Judge Rodney Gilstrap, highlights the strategic importance of this venue for high-stakes wireless patent disputes. The multi-defendant nature, including major carriers and infrastructure vendors like T-Mobile, Verizon, Ericsson, and Nokia, underscores the ecosystem-wide approach often taken in modern 5G patent assertions.
