Daingean Technologies Ltd. v. AT&T Inc. et al

Case Summary

On March 24, 2023, Daingean Technologies Ltd. (“Plaintiff”), represented by Alden Harris, Amir H. Alavi, Demetrios Anaipakos, and Michael McBride of Alavi & Anaipakos, PLLC; Michael Heim, Eric Enger, R. Allan Bullwinkel, Alden Harris, Blaine Larson of Heim Payne & Chorush LLP; and Andrea L. Fair of Ward, Smith & Hill, PLLC, filed an intellectual property lawsuit against AT&T Inc., AT&T Corp., AT&T Communications LLC, AT&T Mobility LLC, AT&T Mobility II LLC, and AT&T Services Inc. (collectively, “Defendants”), seeking damages for alleged patent infringement. This case was filed in the U.S. District Court for the Eastern District of Texas, with Judge Rodney Gilstrap presiding.

In the complaint, the plaintiff stated, “AT&T operates what it calls its 5G and 5G+ networks. The AT&T 5G Networks “cover 230M Americans in 14,000 cities and towns and AT&T 5G+ is now available in parts of 38 cities in the U.S.”

Plaintiff also stated that “AT&T provides more than 100 million U.S. consumers with communications and entertainment experiences across mobile and broadband.”

The plaintiff then alleged, “’AT&T Communications generated 2022 revenues of $117.1 billion. AT&T’s 5G Networks cover nearly 288 million people across the United States.’”

Plaintiff additionally alleged, “5G+ is available in select innovation zones and venues in over 20 states across the US. According to AT&T, 5G is one of ‘two key areas of focus’ for the company.”

Plaintiff further alleged, “The ’803 Patent was assigned to Daingean by Mitsubishi Electric Corporation on August 23, 2022.”

The plaintiff also alleged, “AT&T has infringed directly and continues to infringe directly the ’803 Patent in its implementation of AT&T’s 5G Networks. The infringing activities include, but are not limited to, the manufacture, use, sale, importation, and/or offer for sale of products and/or services from AT&T for operation on its 5G Networks”

The plaintiff then alleged, “The ’976 Patent is generally directed toward uplink transmission management to address latency and reliability requirements and potential coexistence issues.”

Plaintiff additionally alleged, “AT&T has infringed directly and continues to infringe directly the ’976 Patent in its implementation of its 5G network.” 

The plaintiff further alleged, “Daingean holds all rights, title, and interest in and to the ’958 Patent, including the right to bring this suit and recover all past, present and future damages for infringement of the ’958 Patent.”

The plaintiff also alleged, “AT&T has infringed directly and continues to infringe directly the ’958 Patent. The infringing acts include, but are not limited to, the manufacture, use, sale, importation, and/or offer for sale of products and/or services from AT&T that practice or implement the asserted claims, including for example, wireless network devices that generate, transmit, and/or receive the claimed SIB blocks and associated information.”

Plaintiff presented six claims for relief from alleged infringement of the patents-in-suit.

In the prayer for relief, the plaintiff requested declaratory relief and an award of damages with pre- and post-judgment interest.
