Fallübersicht
Die Parteien
⚖️ Kläger
A patent assertion entity (PAE) focused on wireless communications technology, leveraging foundational IP assets in cellular signal processing.
🛡️ Beklagter
One of the world’s largest consumer electronics manufacturers, including 5G-capable smartphones and tablets in its global product portfolio.
Das streitige Patent
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.

Das Urteil und die rechtliche Analyse
Ergebnis
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.
Wichtige rechtliche Fragen
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.
