The case is CommWorks Solutions, LLC v. Grandstream Networks, Inc., No. 2:26-cv-00794 (E.D. Tex.), filed September 4, 2026 in the Marshall Division and assigned to Judge Rodney Gilstrap. CommWorks says it is a Georgia limited liability company. The complaint alleges, on information and belief, that Grandstream is a Delaware corporation based in Boston, Massachusetts, and pleads venue under 28 U.S.C. 1400(b) on the ground that Grandstream has a regular and established place of business in Plano, Texas. CommWorks demands a jury.

Patents and accused products

The asserted patents are U.S. Patent 7,177,285 (issued February 13, 2007), U.S. Patent 7,463,596 (December 9, 2008), and U.S. Patent 6,891,807 (May 10, 2005), each titled Time Based Wireless Access Provisioning; U.S. Patent 7,911,979 (March 22, 2011), titled Time Based Access Provisioning System and Process; and U.S. Patent 7,027,465 (April 11, 2006), titled Method for Contention Free Traffic Detection. The complaint charts claim 1 of the '285, '596, '979, and '465 patents and claim 46 of the '807 patent in Exhibits A to E.

For the four provisioning patents, the accused products are the GXV3240 and GXV3275 IP Multimedia Phones for Android and the GVC3210 and GVC3210 RMT, with Wi-Fi Protected Setup (WPS) functionality for associating devices. For the '465 patent, the accused products are Grandstream Wi-Fi access points, including the GWN7600, GWN7602, GWN7610, GWN7630, and GRP1612W, and the GRP2616 and GRP2613(W) IP phones that support 802.11n, with Wi-Fi Multimedia (WMM) functionality.

What the patents cover

Claim 1 of the '285 patent covers provisioning a wireless device on a network by tracking an operating parameter of the device within a service area, specifically the onset of its signal transmission, and starting provisioning if that onset occurs within a time interval.

Claim 1 of the '596 patent covers associating devices by tracking an operating parameter of a first device, either its power on or the onset of its signal transmission, and automatically associating it with at least one other device if that event occurs within a time interval.

Claim 1 of the '979 patent covers a provisioning process in which provisioning logic tracks a first device's power on or the onset of its signal transmission and sends a signal to start provisioning the device with a network if that event occurs within a designated time interval. A July 19, 2011 certificate of correction changes cited references and wording in claims 19 and 27.

Claim 46 of the '807 patent covers provisioning a wireless device by providing a network access point with an activatable provisioning time interval and starting provisioning if the device begins transmitting its wireless signal to the access point during that interval.

Claim 1 of the '465 patent covers detecting the priority of data frames in a network by extracting a bit pattern from a position in a frame defined by its offset, comparing it with a search pattern, and identifying the frame as a priority frame if the two match.

What the lawsuit is about

CommWorks alleges direct infringement of each patent, literally or under the doctrine of equivalents, and alleges, on information and belief, that Grandstream performed every step of the method claims or conditioned third parties' use of the accused functionality on performing them. It says it or its predecessors satisfied the requirements to collect pre-filing damages, and that marking under 35 U.S.C. 287 does not apply to the asserted method claim of each patent. It asks for damages of no less than a reasonable royalty under 35 U.S.C. 284, interest, and attorneys' fees under 35 U.S.C. 285.

What to watch next

An unopposed application to extend Grandstream's time to answer was filed and the clerk acted on it September 10, 2026. On October 20, 2026, Judge Gilstrap consolidated the case for all pretrial issues with lead case No. 2:25-cv-01257 (E.D. Tex.), and future filings are made in the lead case. The individual cases remain active for trial. Watch the lead case for Grandstream's answer or Rule 12 motion and the scheduling order.
