Cobblestone Wireless, LLC v. AT&T Inc. et al

Case Summary

On December 15, 2022, Cobblestone Wireless, LLC (“Cobblestone” or “Plaintiff”), represented by Reza Mirzaie of Russ August & Kabat, filed an intellectual property lawsuit against AT&T Inc., AT&T Services Inc., AT&T Mobility LLC, and AT&T Corp. (collectively, “AT&T” or “Defendants”), seeking declaratory relief and 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.

Plaintiff filed this complaint for the alleged infringement of U.S. Patent Nos. 8,891,347 (the “’347 patent”), 9,094,888 (the “’888 patent”), 10,368,361 (the “’361 patent”), and 8,554,196 (the “’196 patent”) (collectively, the “Patents-in-Suit”).

In the complaint, the plaintiff alleged, “Defendants make, use, offer for sale, sell, and/or import certain products (‘Accused Instrumentalities’), including (1) cellular base stations that support 3GPP 5G NR beamforming, and (2) cellular handsets that support 3GPP 5G NR beamforming, including without limitation the Apple iPhone 12, [..] and Samsung Galaxy S20 FE, [..], that directly infringe, literally and/or under the doctrine of equivalents, at least Claim 1 of the ’347 Patent.”

The plaintiff then alleged, “Defendants also knowingly and intentionally induce infringement of at least Claim 1 of the ’347 Patent in violation of 35 U.S.C. § 271(b). Through at least the filing and service of this Complaint, Defendants have had knowledge of the ’347 Patent and the infringing nature of the Accused Instrumentalities. Despite this knowledge of the ’347 Patent, Defendants continue to actively encourage and instruct their customers and end users (for example, through user manuals and online instruction materials on their website) to use the Accused Instrumentalities in ways that directly infringe the ’347 Patent. Defendants do so knowing and intending that their customers and end users will commit these infringing acts. Defendants also continue to make, use, offer for sale, sell, and/or import the Accused Instrumentalities, despite their knowledge of the ’347 Patent, thereby specifically intending for and inducing their customers to infringe the ’347 Patent through the customers’ normal and customary use of the Accused Instrumentalities.”

Plaintiff further alleged, “Defendants have also infringed, and continue to infringe, at least Claim 1 of the ’347 Patent by selling, offering for sale, or importing into the United States, the Accused Instrumentalities, knowing that the Accused Instrumentalities constitute a material part of the inventions claimed in the ’347 Patent, are especially made or adapted to infringe the ’347 Patent, and are not staple articles or commodities of commerce suitable for non-infringing use. Defendants have been, and currently are, contributorily infringing the ’347 Patent in violation of 35 U.S.C. §§ 271(c) and (f).”

The plaintiff presented similar allegations for the infringement of ’888 patent, ’361 patent, and ’196 patent.

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

In the prayer for relief, the plaintiffs requested declaration that Defendants have infringed, either literally and/or under the doctrine of equivalents, the patents-in-suit, and that the patents-in-suit are valid, enforceable, and patent-eligible. The plaintiff also requested an award of compensatory and supplemental damages with pre- and post-judgment interest.
