Apple Cleared Of 4G Patent Infringement Claims In 3rd Trial

By Editorial Team

A Texas federal jury has cleared Apple of infringement claims brought by Optis Wireless Technology over patents covering standard-essential 4G wireless technology. This decision comes after the verdicts of two previous juries finding Apple liable were overturned.

The case involved several patents, including:

• 8,411,557 – Mobile station apparatus and random access method
• 8,019,332 – Method for transmitting and receiving control information through PDCCH
• 8,102,833 – Method for transmitting uplink signals
• 8,385,284 – Control channel signaling using a common signaling field for transport format and redundancy version
• 9,001,774 – System and method for channel estimation in a delay diversity wireless communication system

The trial took place in the U.S. District Court for the Eastern District of Texas, with law firms Gillam Smith, Gray Reed, Irell & Manella, McKool Smith, and WilmerHale representing the involved parties.

Apple Inc. was the defendant in this case, and the presiding judge was James Rodney Gilstrap.

This verdict marks a significant legal victory for Apple in this ongoing patent dispute.
