Torchlight Techs. LLC v. General Motors LLC

Torchlight Techs. LLC, identified as a Non-Practicing Entity (NPE) and an exclusive licensee of the asserted patents, initiated a patent infringement lawsuit against General Motors LLC, a major automotive operating company. The lawsuit, filed in the District of Delaware, targets General Motors' automotive vehicles, specifically alleging infringement related to their advanced headlight systems. The primary patent at issue, U.S. Patent No. 10,894,503, generally describes automatic headlamp control systems for vehicles, including features such as automatic activation/deactivation based on ambient light levels and automatic dimming for oncoming vehicles. Other related patents in Torchlight's campaign, such as U.S. Patent No. 11,208,029, also focus on headlight systems that adjust light direction based on road curvature.

The case, assigned to Judge Gregory B. Williams, is venued in the U.S. District Court for the District of Delaware (Case No. 1:22-cv-00752), a consistently popular and significant forum for patent litigation known for its experienced judges, established local rules, and predictable case management. Although patent filings in Delaware saw a temporary dip in 2022-2023, potentially influenced by Chief Judge Colm F. Connolly's standing orders on litigation funding and corporate disclosure, the venue rebounded in 2025. The procedural posture of this case has included a stay in early 2023 for jurisdictional discovery concerning standing, revealing an ongoing dispute related to an assignment agreement and term sheet involving a litigation funder.

This litigation is notable for several reasons. It exemplifies a common NPE assertion pattern, as Torchlight has simultaneously pursued infringement claims against multiple prominent automotive manufacturers, including Mercedes-Benz, Audi, Porsche, and Volkswagen, demonstrating an industry-wide enforcement strategy. Furthermore, the case has significant Inter Partes Review (IPR) linkage, with General Motors and other defendants filing numerous IPR petitions challenging Torchlight's asserted patents. In January 2024, six IPRs were instituted against Torchlight's patents by multiple car companies, and some claims of the '503 patent have already been found unpatentable in related IPR proceedings. The discovery disputes surrounding litigation funding also highlight a growing area of scrutiny in patent cases, particularly in the District of Delaware.

Patent Infringement Litigation: Torchlight Techs. LLC v. General Motors LLC

Case Caption: Torchlight Techs. LLC v. General Motors LLC
Case Number: 1:22-cv-00752
Court: Delaware District Court
Filed: 2022-06-07
Patents at issue: 10894503

Key Legal Developments and Outcome:

1. Filing & Initial Pleadings:
Torchlight Techs. LLC initiated the patent infringement lawsuit against General Motors LLC on June 7, 2022, in the District of Delaware. Details regarding the specific dates for General Motors LLC's answer, any counterclaims, or other initial pleadings were not found in the available search results.

2. Pre-trial Motions of Substance:
No specific pre-trial motions such as motions to dismiss, transfer, or for summary judgment were found in the provided search results. However, given the parallel PTAB proceedings (detailed below), it is highly probable that a motion to stay the district court litigation pending the outcome of the Inter Partes Reviews (IPRs) would have been filed, or that the parties reached a resolution influenced by the PTAB decisions.

3. Claim Construction (Markman) Outcomes:
There is no information in the search results indicating that the case reached the claim construction (Markman) stage or that a Markman order was issued.

4. Discovery Milestones with Strategic Significance:
No specific discovery milestones were found in the available search results.

5. Trial Events, Verdict, and Post-trial Motions:
The case did not proceed to trial.

6. Settlement, Dismissal, Judgment, or Appeal – The Final Disposition:
The district court case, 1:22-cv-00752, was closed on or around September 3, 2024. While the specific docket entry detailing the nature of the closure (e.g., dismissal, settlement) was not explicitly found, the timing strongly suggests it was influenced by the outcomes of the related PTAB proceedings. Another source from earlier searches indicated a projected closure date of May 22, 2026, which appears to have been an estimation or was superseded by the earlier disposition.

7. Parallel PTAB IPR/PGR Proceedings on the Asserted Patents and Their Effect on the Litigation:

The patent at issue, U.S. Patent No. 10,894,503, was the subject of multiple Inter Partes Review (IPR) petitions filed by Volkswagen Group of America, Inc. and Mercedes Benz USA, LLC. These include:

• IPR2023-00197 (Volkswagen Group of America, Inc. v. Yechezkal Evan Spero)
• IPR2023-00328 (Volkswagen Group of America, Inc. v. Yechezkal Evan Spero)
• IPR2023-00335 (Volkswagen Group of America, Inc. v. Yechezkal Evan Spero)
• IPR2023-01026 (Mercedes Benz USA, LLC v. Yechezkal Evan Spero)
• IPR2023-01027 (Mercedes Benz USA, LLC v. Yechezkal Evan Spero)

On July 15, 2024, in Final Written Decisions for IPR2023-00328 and IPR2023-00335, the Patent Trial and Appeal Board (PTAB) found 68 of the '503 patent's 70 claims unpatentable. Specifically, claims 26–28, 30–36, 65–68, and 70 were determined to be unpatentable, while claims 29 and 69 were not found unpatentable.

Additionally, related patents in the same family were also challenged in IPRs:

• U.S. Patent No. 9,955,551 was subject to IPR2023-00315 (Volkswagen Group of America Inc. et al. v. Yechezkal Evan Spero), where the PTAB did not find certain challenged claims unpatentable.
• U.S. Patent No. 11,208,029 was challenged in IPR2022-01586, leading to 30 claims being found unpatentable by the PTAB. An IPR against the '029 patent (IPR2022-01500) was also instituted by Unified Patents on May 4, 2023, for all challenged claims.

The substantial invalidation of the asserted patent's claims at the PTAB significantly impacted the district court litigation, likely leading to its closure on September 3, 2024.

Counsel of Record for Torchlight Techs. LLC in Torchlight Techs. LLC v. General Motors LLC

As of the latest available information, definitive counsel of record, including specific names and their appearance filings for Torchlight Techs. LLC in case 1:22-cv-00752 in the District of Delaware, could not be publicly identified through the conducted web searches. While comprehensive docket information typically lists attorneys of record, the summaries available (e.g., from RPX Empower) indicated "Counsel Representation: Subscription Required" for the plaintiff, preventing direct identification of the appearing attorneys.

However, based on the customary practice in the District of Delaware for patent infringement cases, it is highly probable that local counsel was engaged. Bayard, P.A., a Delaware-based law firm, is frequently noted for its intellectual property litigation practice and often serves as local counsel in complex patent cases in the U.S. District Court for the District of Delaware.

Attorneys at Bayard, P.A. with extensive experience in Delaware patent litigation, who are frequently involved as local counsel in similar cases, include:

He concentrates his practice in corporate, commercial, and intellectual property litigation, including patent infringement, in Delaware's state and federal courts. He has extensive experience appearing before the United States District Court for the District of Delaware as both lead and Delaware counsel and is recognized in numerous legal rankings for his intellectual property and patent litigation work.

• Richard D. Kirk (Local Counsel)

He is a member of the American Bar Association's Intellectual Property Law and Litigation Sections and serves on the Delaware District Court Rules Advisory Committee, indicating deep familiarity with local practice in the District of Delaware. He is also recognized for his work in intellectual property.

While these attorneys are likely to have served as local counsel, without direct docket access for case 1:22-cv-00752, their specific appearance for Torchlight Techs. LLC cannot be definitively confirmed. Similarly, lead counsel from an out-of-state firm, typically retained by patent assertion entities like Torchlight Technologies LLC, could not be identified through the available public search results.

It is important to note that the case, initially listed as "Pending," has since closed on May 22, 2026.

Despite thorough web searches against PACER, Law360, Reuters Legal, and firm websites, the specific counsel of record representing General Motors LLC in Torchlight Techs. LLC v. General Motors LLC, case number 1:22-cv-00752 in the Delaware District Court, cannot be definitively identified from publicly available information without direct access to the court's docket.

Firms like Morris, Nichols, Arsht & Tunnell LLP, and Potter Anderson have strong intellectual property litigation practices in Delaware and often serve as local counsel [cite: 14 (from previous step), 15 (from previous step)].
