WirelessWerx IP v. Subaru: Infringement Case Consolidated in E.D. Texas
WirelessWerx IP, LLC filed a patent infringement action against Subaru Corp. in the Eastern District of Texas, asserting US7323982B2 covering methods and systems to control movable entities. After 129 days, the court ordered the case consolidated for all pretrial issues into lead case 2:25-cv-00182, signalling a broader multi-defendant campaign by WirelessWerx.
Multi-defendant ADAS patent campaign lands in E.D. Texas
On 21 February 2025, WirelessWerx IP, LLC — a non-practising entity holding US7323982B2 — filed suit against Subaru Corp. in the Eastern District of Texas (Case No. 2:25-cv-00225). The asserted patent claims a method and system to control movable entities, a technology domain that intersects with connected-vehicle and advanced driver-assistance system architectures. Ramey LLP, a firm with an established E.D. Texas NPE docket, represented the plaintiff.
On 30 June 2025, after 129 days, the court issued a consolidation order merging this case with lead case 2:25-cv-00182 for all pretrial issues. Consolidation is a procedural mechanism — not a merits ruling — that groups related cases to promote judicial efficiency. Individual member cases, including Subaru’s, remain independently active for trial purposes, meaning no infringement or validity determination has been made.
The consolidation order strongly suggests WirelessWerx filed parallel actions against multiple automotive defendants simultaneously — a pattern consistent with NPE campaign litigation targeting a defined technology area across an industry. The lead case designation implies at least one earlier-filed action, reinforcing the scale of the assertion. Key unknowns from the public record include the identity and number of co-defendants, claim construction positions, and whether any defendant has filed an IPR challenge against US7323982B2.

Case consolidated: what the pretrial merger means for Subaru
Consolidation is procedural, not a merits decision
Under Federal Rule of Civil Procedure 42(a), courts may consolidate cases sharing common questions of law or fact. The E.D. Texas order merges this case with lead case 2:25-cv-00182 for all pretrial proceedings — including scheduling, discovery, and claim construction — while preserving each defendant’s right to a separate trial. No finding of infringement or invalidity has been made.
FRCP 42(a) consolidationConsolidation signals a coordinated multi-defendant campaign
WirelessWerx’s consolidation into a lead case is consistent with NPE litigation strategy: file against multiple defendants in a single venue, then consolidate to control claim construction globally. A favourable Markman ruling in the lead case would apply across all member cases, including Subaru’s, amplifying the commercial pressure on each individual defendant to settle before trial.
NPE multi-defendant strategySubaru’s case is active — trial rights are preserved
Despite consolidation, Subaru’s individual case remains live for trial purposes. Subaru is represented by DLA Piper (Chicago) and Findlay Craft PC — a combination suggesting both national litigation firepower and E.D. Texas local expertise. Subaru’s strategic options include IPR petition against US7323982B2, invalidity defences at claim construction, and potential co-defendant cost-sharing on prior art searches.
Trial rights preservedAutomotive OEMs face coordinated IP risk on connected-vehicle systems
The assertion of a movable-entity control patent against Subaru in E.D. Texas — alongside what appears to be a broader defendant class — suggests growing NPE activity targeting connected-vehicle and telematics features. OEMs and Tier 1 suppliers with similar system architectures should monitor lead case 2:25-cv-00182 closely, as claim construction outcomes will set boundaries for the entire defendant group.

Official order — verbatim text
The consolidation order is strictly procedural: it does not adjudicate infringement, validity, or damages. The court’s instruction that ‘individual cases remain active for trial’ confirms Subaru retains full litigation rights. The directive for all future filings to occur in lead case 2:25-cv-00182 centralises pretrial management — meaning claim construction, discovery disputes, and scheduling orders will be issued in the lead docket and bind all member cases including this one.
US7323982B2 — Method and system to control movable entities
US7323982B2, filed under application number US11/105932, claims a method and system to control movable entities — a broad technical framing that encompasses wireless command-and-control architectures for vehicles, drones, or autonomous systems. The patent’s granted status means it has survived examination, though it has not yet been adjudicated for validity in this litigation. The filing date of the underlying application is relevant to assess prior art exposure relative to early telematics and vehicle-control system publications.
In the connected-vehicle context, a patent claiming movable entity control systems carries significant strategic weight. Modern automotive OEMs integrate wireless communication, fleet management, and driver-assistance coordination features that could potentially be read against broadly drafted claims in this space. WirelessWerx’s decision to assert this patent against Subaru — an OEM with a growing ADAS and connected-car portfolio — suggests the patent holder views contemporary vehicle architectures as within the claim scope. Competitors and Tier 1 suppliers operating in telematics, V2X, and over-the-air update systems should conduct independent claim mapping.
Should you run an FTO analysis against US7323982B2?
Any company developing or supplying wireless systems for movable entity control — including vehicle telematics units, fleet management platforms, connected ADAS components, or autonomous vehicle command systems — should assess their exposure to US7323982B2. The E.D. Texas filing against Subaru, combined with what appears to be a multi-defendant consolidation, suggests WirelessWerx is actively enforcing this patent across the automotive OEM space. A proactive FTO analysis is particularly urgent for OEMs not yet named in the lead case.

WirelessWerx’s coordinated filing strategy in E.D. Texas reflects a playbook increasingly used against automotive OEMs asserting system-level patents.
Monitor lead case 2:25-cv-00182 for claim construction outcomes
The Markman hearing in the lead case will define claim scope for all consolidated defendants. Any OEM or Tier 1 supplier whose connected-vehicle or telematics products could read on US7323982B2 should track this proceeding — an unfavourable construction could expand the exposure surface beyond current defendants.
IPR remains the sharpest tool for Subaru and co-defendants
US7323982B2 (application filed as US11/105932) is a granted utility patent with a defined prosecution history. Filing an inter partes review petition — ideally coordinated across co-defendants to share costs — could neutralise the asserted claims before trial and eliminate damages exposure entirely if institution is granted.
