Case Overview
The Parties
⚖️ Plaintiff
A patent assertion entity (PAE) focused on wireless communications technology, leveraging foundational IP assets in cellular signal processing.
🛡️ Defendant
One of the world’s largest consumer electronics manufacturers, including 5G-capable smartphones and tablets in its global product portfolio.
The Patent at Issue
This lawsuit centered on U.S. Patent No. 6,813,742 B2, which covers wireless communications / turbo coding. Turbo codes are a data encoding method critical to cellular signal processing, foundational to 3G and 4G LTE standards, and retain relevance in some 5G signal chain architectures.

The Verdict & Legal Analysis
Outcome
On January 4, 2024, Chief Judge Albright granted the Joint Motion to Dismiss with Prejudice, formally closing Case No. 1:22-cv-01163. This outcome means TurboCode is permanently barred from re-asserting the same claims against TCL on this patent. No damages figure was publicly disclosed, indicating a likely confidential settlement or licensing agreement between the parties.
Key Legal Issues
The case was initiated as a straightforward patent infringement action under 35 U.S.C. § 271. While no substantive judicial rulings on claim construction, validity, or infringement were issued, the patent’s relevance to TCL’s accused 5G products would have been a central dispute. Turbo codes became critical to cellular communications with 3GPP standards, and while 5G’s primary channel coding shifted to LDPC codes for data, turbo codes retain a role in control channel encoding. This highlights the ongoing challenge of asserting legacy wireless communication patents against evolving 5G standards.
