Nusbaum

Profile: "Nusbaum" (database entry)

Important caveat on identity. The entity indexed in the case data as "Nusbaum" does not appear to be a company. It is the lead plaintiff name in Nusbaum v. Hou et al., No. 2022‑1095‑PAF (Del. Ch.), a shareholder derivative action filed on November 28, 2022 in the Delaware Court of Chancery. Public records (TuSimple Holdings Inc. / CreateAI Holdings Inc. SEC filings) identify the plaintiff only as a stockholder bringing suit "purportedly on behalf of the Company." I could not verify any corporate registration, headquarters, employees, revenue, or product line for a "Nusbaum" legal entity; the surname recurs elsewhere (e.g., a hospital-ownership dispute) with no apparent connection. No founded year, ticker, or parent can be confirmed.

Role in the tracked case. The single tracked matter is not patent litigation. It is a fiduciary‑duty derivative suit against current and former directors and officers of TuSimple Holdings (Xiaodi Hou, Mo Chen, Brad Buss, Karen Francis, Michelle Sterling, Reed Werner) and Hydron Inc., with TuSimple named as nominal defendant. Claims concerned a related‑party transaction with Hydron and a restructuring of the company's board.

Litigation posture. With one plaintiff‑side case and zero defendant‑side cases, this entry reflects an individual shareholder plaintiff (represented in a derivative action), not an operating company defending patent claims and not a non‑practicing entity asserting an acquired patent portfolio. Venue is the Delaware Court of Chancery, a corporate‑governance forum, not a patent venue such as the Eastern District of Texas.

Context. Nusbaum was consolidated in 2023 with Young v. Hou and Wolfson v. Hou; a consolidated complaint was filed July 24, 2023. The consolidated Delaware action and the parallel federal Wilhoite v. Hou action (S.D. Cal.) settled in December 2024 for $42.5 million without admissions, with final approval in July 2025. The underlying company, TuSimple, later renamed itself CreateAI (July 2025) and is now asserting patent and trade‑secret claims of its own against Bot Auto in Texas.
