Iarnach Technologies Ltd. v. AT&T Corp. et al

Case Summary

On May 26, 2023, Iarnach Technologies Ltd. (“Iarnach” or “Plaintiff”), represented by Alden Harris, Blaine A. Larson, Eric J. Enger, Michael F. Heim, and Robert A. Bullwinkel of Heim Payne & Chorush LLP; and Amir Alavi and Demetrios Anaipakos of Alavi & Anaipakos, 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, “AT&T” or “Defendants”), seeking injunctive relief for alleged infringement of the U.S. patents owned by the plaintiff. 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 alleged, “The Accused Instrumentalities include all components necessary for AT&T to provide fiber-optic networks and network services to its customers, including all hardware and software, optical line terminals (ONTs), and optical network units (ONUs)/optical network terminals (ONTs). This includes both residential and commercial customers, as well as fiber used in AT&T’s wireless backhaul."

Plaintiff also alleged, “The plaintiff filed this complaint for the alleged infringement of U.S. Patent Nos. 8,712,242 (‘the ’242 Patent’), 8,934,359 (‘the ’359 Patent’), 8,942,378 (‘the ’378 Patent’), 9,363,013 (‘the ’013 Patent’) and 9,806,892 (‘the ’892 Patent’) (collectively, the ‘Asserted Patents’) owned by the plaintiff." 

The plaintiff then alleged, “The ’242 Patent is generally directed toward the ranging process in a passive optical network. Because an OLT does not know the position of an ONU on which ranging is to be performed, the OLT will open a quiet window to perform the ranging. ’242 Patent at 1:64-2:2. However, a quiet window opened for ranging that lasts too long will disrupt the operation of other ONUs that are in the operation state, thereby lowering their transmission efficiency.”

Plaintiff further alleged, “On information and belief, AT&T has infringed directly and continues to infringe directly the ’242 Patent in its implementation of AT&T’s fiber-optic networks and network services, including AT&T Fiber internet services. The infringing activities include, but are not limited to, the manufacture, use, sale, importation, and/or offer for sale of products and/or services by AT&T for operation on its fiber-optic networks and network services that are capable of performing ranging between OLTs and ONUs.”

Additionally, the plaintiff alleged, “AT&T provides multiple AT&T Fiber internet service plans, as the marketing materials from AT&T make clear. See https://www.att.com/internet/fiber/ (last visited May 8, 2023). These service plans include providing access to AT&T’s fiber-optic networks and network services. On information and belief, the products implemented by AT&T and used in its fiber- optic networks include hardware and/or software that is configured to be capable of performing ranging between OLTs and ONUs.”

The plaintiff also alleged that “Iarnach is informed and believes, and on that basis alleges, that AT&T indirectly infringes at least claim 1 of the ’242 patent by active inducement in violation of 35 U.S.C. § 271(b), by at least manufacturing, supplying, distributing, selling, and/or offering for sale the Accused Instrumentalities to its customers with the knowledge and intent that use of those products would constitute direct infringement of the ’242 patent.”

Plaintiff presented five claims for relief from alleged infringement of the Asserted Patents owned by the plaintiff. 

In the prayer for relief, the plaintiff requested declaratory relief. The plaintiff also requested an award of damages with pre- and post-judgment interest and attorneys’ fees incurred by the plaintiff.
