Telecom giants face infringement suits from Pegasus

Three major US networks hit with infringement lawsuits over 3GPP 4G/LTE and 5G standards | Complaint alleged ‘stolen’ patents are essential to wireless telecommunications technology | Lawsuits alleged 11 patents at issue.

T-Mobile, AT&T, and Verizon have been accused of infringing 11 of Pegasus Wireless Innovation’s patents.

Pegasus filed three separate lawsuits in the US District Court for the Eastern District of Texas, alleging the trio had stolen patents that cover fundamental technologies related to wireless telecommunications.

The complaint, filed on December 29, 2023, claimed that T-Mobile, AT&T, and Verizon use the patented technology in their mobile network and devices.

Pegasus accused the trio of infringing 11 patents, named US Patent numbers: 11,627,631; 10,181,931; 10,616,932; 11,405,942; 10,594,460; 10,721,118; 11,219,000; 10,638,463; 11,540,272; 9,894,644; and 10,009,161.

These patents were originally developed by researchers at KT Corporation, a provider of mobile voice and data telecommunications based in Korea.

Pegasus acquired the rights to these patents through an exclusive license agreement with KT in September 2022.

KT has been actively involved in the development of advanced telecommunications platforms, including 4G/LTE and 5G technologies.

Pegasus alleged that the trio operate and sell access to a mobile network infringing the disputed patents by operating in accordance with 3GPP 4G/LTE and 5G standards.

Pegasus claimed to have provided T-Mobile, AT&T, and Verizon with a notice of the patents and attempted to engage in negotiations to resolve the dispute.

However, they were unable to reach licensing agreements on fair, reasonable, and non-discriminatory terms.

Pegasus is seeking damages and injunctive relief.
