Torchlight Techs. LLC v. Daimler AG et al.

Torchlight Techs. LLC, identified as an "apparently-funded" Non-Practicing Entity (NPE), has initiated patent infringement litigation against major automotive manufacturers. The defendant in this specific case is Daimler AG, a German multinational automotive corporation. While Volkswagen Group of America, Inc. was initially a defendant, it was later voluntarily dismissed from the action. Torchlight Techs. LLC is an exclusive licensee of the asserted patents. The accused products and technology relate to automotive headlight systems, specifically those that increase light in the direction of road curvature. The patent at issue in this case is U.S. Patent No. 10,894,503, which, alongside other patents asserted by Torchlight in related cases, generally concerns adaptive headlight technology.

The case, 1:22-cv-00751, was filed on June 7, 2022, in the U.S. District Court for the District of Delaware and is currently assigned to Judge Gregory B. Williams. The District of Delaware is a prominent venue for patent litigation, often chosen for its judicial sophistication, docket reliability, and a mature body of patent-specific precedent. The court's procedural rigor, including tight deadlines for infringement and invalidity contentions, is notable.

This case is part of a broader assertion campaign by Torchlight Technologies against multiple automotive companies, including Mercedes-Benz (f/k/a Daimler), Audi, Porsche, and General Motors. The campaign has led to several Inter Partes Reviews (IPRs) being filed against Torchlight's asserted patents by the defendants, with multiple IPRs instituted by the Patent Trial and Appeal Board (PTAB) challenging the patents, including one directly related to U.S. Patent 11,208,029 (a related patent to 10894503, which also describes headlight systems) where trial was instituted on all challenged claims. The litigation also involves discovery disputes related to funding agreements and assignment agreements, suggesting that Torchlight Technologies is a funded NPE.

• An appeal was filed by the Patent Owner (Yechezkal Evan Spero) to the U.S. Court of Appeals for the Federal Circuit from a Final Written Decision of the PTAB in IPR2023-00197 concerning the '503 patent, which was dated June 20, 2024.

Parallel PTAB IPR/PGR Proceedings:
Several Inter Partes Review (IPR) proceedings have been initiated at the Patent Trial and Appeal Board (PTAB) challenging patents related to the Torchlight Techs. LLC v. Daimler AG et al. litigation. The inventor, Yechezkal Evan Spero, is identified as the Patent Owner in these IPRs.

• IPR2023-00197: Filed by Volkswagen Group of America, Inc. and Porsche Cars North America, Inc. against U.S. Patent No. 10,894,503.
  • 2023-06-21: The PTAB instituted inter partes review.
  • 2024-06-20: The PTAB issued a Final Written Decision.
  • 2024-08-06: An Order denying Director Review of the Final Written Decision was issued.
  • 2024-06-20 (or later): Patent Owner Yechezkal Evan Spero filed a Notice of Appeal to the U.S. Court of Appeals for the Federal Circuit from the Final Written Decision.
• IPR2023-00315: Filed by Volkswagen Group of America, Inc. (and later joined by Porsche Cars North America, Inc.) against U.S. Patent No. 9,955,551, which is a related patent to the one asserted in the district court case.
  • 2023-07-17: The PTAB instituted inter partes review.
  • 2024-06-25: Brooks Kushman secured a favorable final written decision for Evan Spero, finding that petitioners had not proven claims 25, 27, 33, 35, 41, 43, and 48–55 of the '551 patent unpatentable, while other claims were found unpatentable.
• IPR2022-01586: Filed by Volkswagen Group of America, Inc. against U.S. Patent No. 11,208,029, another related patent asserted in the Torchlight Technologies LLC v. Daimler AG et al. and Torchlight Technologies LLC v. General Motors LLC et al cases.
  • 2024-05-28: Sterne Kessler secured a favorable final written decision for Volkswagen, finding 30 claims of the '029 patent unpatentable.

The existence of these IPRs and their outcomes, particularly the unpatentability findings for claims in related patents and the ongoing appeal for patent 10,894,503, can significantly impact the district court litigation by narrowing or eliminating the asserted claims.
