VB Assets, LLC v. General Motors Holdings LLC

Case Overview and Background

This active patent infringement suit pits VB Assets, LLC, a non-practicing entity (NPE), against automotive giant General Motors Holdings LLC (GM). VB Assets was formed to license and enforce a portfolio of patents originating from VoiceBox Technologies, an early developer of conversational AI and voice recognition technology. It is currently engaged in a broad litigation campaign, having also sued other major technology and automotive companies including Amazon, Apple, Samsung, and Ford over the same patent family. The defendant, General Motors, is a major operating company and one of the world's largest vehicle manufacturers. The accused technology in this case is understood to be the voice-controlled functionalities within GM's vehicle infotainment systems and associated services, such as OnStar, which increasingly incorporate sophisticated voice assistants.

The lawsuit is filed in the U.S. District Court for the Eastern District of Texas (EDTX), a venue long favored by patent plaintiffs, particularly NPEs, for its experienced judiciary and case management procedures that are often seen as beneficial for patentees. The case has been assigned to Chief Judge Rodney Gilstrap, who manages the largest patent docket in the United States. VB Assets asserts U.S. Patent No. 10,510,341, titled "System and method for multi-intent and/or multi-sentence natural language understanding." This patent generally covers technology for processing complex, multi-part user requests spoken in natural language. The case is notable as it represents the expansion of "big tech" voice assistant patent litigation into the automotive sector. The credibility of the asserted patent portfolio is bolstered by a prior, successful jury verdict where VB Assets was awarded over $40 million in a case against Amazon involving related patents and similar voice-recognition technology.

Key Legal Developments and Case Status

Analyst Note: A significant discrepancy exists between the case metadata provided and publicly available court records. Search results indicate that case number 2:25-cv-00621 in the U.S. District Court for the Eastern District of Texas is a patent infringement suit filed by VB Assets, LLC against Success Foods Management Group, LLC d/b/a Torchy's Tacos, not General Motors Holdings LLC.

However, a separate patent infringement lawsuit between the specified parties, VB Assets and General Motors, has been identified in a different venue. The correct case appears to be VB Assets, LLC v. General Motors Holdings LLC et al., Case No. 1:24-cv-01279, in the U.S. District Court for the District of Delaware. The analysis below pertains to this correct and active litigation.

As of May 2026, the litigation between VB Assets and General Motors in Delaware is in its early stages. The public record contains limited substantive developments, which is typical for a case filed in late 2024.

Filing and Initial Proceedings

• Complaint (2024-10-09): VB Assets, LLC filed its patent infringement complaint against General Motors Holdings LLC in the District of Delaware. While the specific complaint for the GM case was not retrieved in searches, a contemporaneous complaint filed by VB Assets against Samsung in a different matter asserts U.S. Patent No. 10,510,341, the patent-in-suit in this case, among others from the same family. That complaint accuses Samsung's "Bixby" voice assistant, suggesting the suit against GM likewise targets its vehicle infotainment and voice command systems.
• Case Status: The case is currently active. No answer, substantive motions, or court orders have appeared in public legal news or databases as of the current date.

Parallel Proceedings (PTAB)

• Inter Partes Review (IPR): There is no public record of General Motors having filed an IPR petition with the Patent Trial and Appeal Board (PTAB) against U.S. Patent No. 10,510,341 to date. The patent is part of a broader litigation campaign by VB Assets, and other defendants in parallel cases, such as Amazon, have previously filed IPRs against related patents from the same family. It remains a strategic option for GM as the district court case proceeds.

Given the case's recent filing date, key milestones such as substantive pre-trial motions, claim construction (Markman) hearings, significant discovery events, and trial are not expected to have occurred yet. The case will likely follow the typical progression of patent litigation, with scheduling conferences, discovery, and claim construction briefing expected to occur throughout 2026.

• Johnny Ward of Ward, Smith & Hill, PLLC (Longview, TX)

Note: The specific attorneys from these firms who will formally file a notice of appearance in the case against General Motors may vary. This list is compiled based on representation in prior and concurrent VB Assets, LLC lawsuits and standard practices in the Eastern District of Texas. As of May 7, 2026, the official complaint and notices of appearance have not been located in publicly available records, which is not unusual in the early stages of a case.

Defendant's Counsel of Record

As of the current date, counsel for defendant General Motors Holdings LLC (GM) has not formally filed a notice of appearance in the Eastern District of Texas for case number 2:25-cv-00621. The case is in its early stages, and it is common for defendants to receive a waiver of service, allowing them additional time to respond and for counsel to appear.

However, analysis of a parallel and preceding case provides a strong indication of the legal team GM has retained. VB Assets, LLC filed a similar patent infringement lawsuit against GM in the U.S. District Court for the District of Delaware on October 31, 2024 (VB Assets, LLC v. General Motors Holdings LLC et al., D. Del., No. 1:24-cv-01279). It is highly probable that the same national and local counsel representing GM in the Delaware action will also represent the company in the Eastern District of Texas matter.

Based on counsel of record in the Delaware case and the firm's extensive history representing GM in high-stakes patent matters, the anticipated defense team is as follows:

Lead Counsel

• Firm: Fish & Richardson P.C.
  • Attorneys (Anticipated): While specific attorneys have not yet appeared in the Texas case, partners from Fish & Richardson are expected to lead the defense. The firm has a deep bench of nationally recognized patent litigators.
  • Office Location(s): The firm will likely draw attorneys from its national patent litigation group, with potential involvement from its Dallas, Texas and Wilmington, Delaware offices.
  • Relevant Experience: Fish & Richardson has a long-standing relationship with General Motors, recently representing the company in a significant design patent dispute before the en banc U.S. Court of Appeals for the Federal Circuit (LKQ Corp. v. GM Glob. Tech. Operations LLC). The firm is consistently ranked as a top patent defense firm in the country.

Local Counsel (Anticipated for EDTX)

• Firm: (Not Yet Appeared)
  • Attorneys (Anticipated): A Texas-based firm with deep experience in the Eastern District will likely be retained as local counsel. The specific firm and attorneys are not yet known.
  • Role: Local counsel's role will be to provide guidance on local court rules and procedures, assist with hearings, and facilitate communication with the court.

In-House Counsel

• Role: In-house patent counsel at General Motors will actively manage the litigation strategy, coordinate with outside counsel, and oversee the case internally. The specific in-house attorneys assigned to this matter are not publicly known.
