Trade Secret Litigation

State of play.

• Apple v. OpenAI is the defining trade secret case in the AI hardware race. Apple filed suit in the Northern District of California alleging a coordinated scheme — through recruiting practices, former-employee conduct, and supplier deception — to extract confidential hardware designs, manufacturing processes, and supply chain strategies for the iPhone, Apple Watch, and MacBook (→ Apple sues OpenAI and two ex-employees for stealing trade secrets to build AI hardware, Apple sues OpenAI, alleging coordinated trade secret theft for AI hardware, Apple Sues OpenAI and Hardware Chief Tang Tan for Alleged Trade Secret Theft to Build Competing Devices, Apple Sues OpenAI for Trade Secret Theft Amid Hardware Partnership Rupture).
• Apple has moved for a preliminary injunction; OpenAI has moved to dismiss. Apple seeks to bar OpenAI, io Products, Tang Tan, and Chang Liu from accessing or using the alleged trade secrets during litigation; OpenAI argues Apple failed to identify any protectable trade secret or plausible misappropriation (→ Apple asks court to block OpenAI from using alleged trade secrets, OpenAI Rejects Apple’s Injunction Bid in Trade-Secret Fight, OpenAI seeks to dismiss Apple’s trade-secrets lawsuit over hardware hiring). The October 1 preliminary injunction hearing is the immediate inflection point.
• OpenAI has gone public with internal communications as a litigation counteroffensive, releasing private emails to rebut Apple's allegations — a tactic that signals both parties are managing the public narrative alongside the docket (→ Apple sues OpenAI over alleged trade-secret theft tied to AI devices, OpenAI seeks to dismiss Apple’s trade-secrets lawsuit over hardware hiring).
• A parallel data-licensing dispute tests whether AI training on licensed case law constitutes misappropriation. In Fastcase v. Alexi Technologies, a D.C. federal court is hearing arguments on whether Alexi's pivot from a human-reviewed memo service to an AI-driven platform breached "internal use" restrictions — with Fastcase seeking destruction of both datasets and trained model weights (→ Fastcase Sues Alexi Over Unauthorized AI Training Using Licensed Case Law).
• For counsel advising technology companies, AI developers, or any client competing for senior hardware or IP talent, the practical baseline is: the Apple v. OpenAI litigation will set the terms for how courts treat institutional knowledge, recruiting-channel misappropriation, and injunctive relief in AI hardware disputes — and the preliminary injunction ruling will arrive before trial.

Where things stand.

• Apple v. OpenAI is pending in the Northern District of California, with the complaint alleging Tang Tan extracted proprietary information from job candidates during OpenAI interviews while still employed at Apple, that OpenAI encouraged candidates to bring prototypes and components, and that OpenAI deceived Apple's manufacturing partners to access proprietary metal finishing technologies; over 400 former Apple employees now work at OpenAI (→ Apple sues OpenAI and two ex-employees for stealing trade secrets to build AI hardware, Apple sues OpenAI, alleging coordinated trade secret theft for AI hardware).
• The preliminary injunction posture is the near-term operative question. Apple seeks to freeze OpenAI's access to the disputed information before trial; OpenAI's dismissal motion, if granted, would moot the injunction — making the motion-to-dismiss ruling the threshold event (→ Apple asks court to block OpenAI from using alleged trade secrets, OpenAI seeks to dismiss Apple’s trade-secrets lawsuit over hardware hiring).
• The Flextronics/Ricci case illustrates the in-house counsel conflict vector. A Northern District of California judge refused to dismiss claims against a former deputy GC who allegedly arranged favorable patent assignments to a startup he secretly co-founded — keeping alive fraud, breach of fiduciary duty, and trade secret misappropriation claims, with downstream exposure in patent disputes involving Ford, GM, and Toyota (→ California Judge Keeps Flextronics IP-Theft Suit Against Former GC Deputy Alive).
• Data license "internal use" restrictions are under judicial scrutiny in the AI context. Fastcase v. Alexi turns on whether a licensee's evolution from human-reviewed legal memos to a commercial AI platform breached scope restrictions; Fastcase seeks model-weight destruction as a remedy, treating trained weights as infringing derivative works (→ Fastcase Sues Alexi Over Unauthorized AI Training Using Licensed Case Law).
• Patent disclosure remains a hard cutoff for trade secret protection. The Federal Circuit's ruling in International Medical Devices v. Cornell holds that patent-disclosed designs are "generally known" under California's UTSA and ineligible for trade secret protection — a ruling that directly threatens dual patent/trade secret strategies .
• Contractual restrictions on investigation can toll the DTSA statute of limitations. In SkyBell Technologies v. Alarm.com, the Eastern District of Virginia held that a reverse engineering prohibition in a Development and Integration Agreement prevented the plaintiff from reasonably discovering misappropriation while the agreement was in force .
• DTSA ownership and standing are active threshold issues. The First Circuit's decision in ZipBy USA v. Parzych addresses who holds enforceable rights when ownership is ambiguous — increasingly litigated in joint development, employee contribution, and AI-assisted development scenarios .
• Taiwan is prosecuting semiconductor trade secret theft as a national security matter, with a 10-year sentence against a former Tokyo Electron/TSMC employee and corporate fines and damages against Tokyo Electron's Taiwan subsidiary .
• China's enforcement posture is escalating on multiple tracks. Punitive damages in trade secret cases rose 29.4% year-over-year, with a record RMB 640 million award; China's new Trade Secrets Regulation is in effect; and USTR's 2026 Special 301 Report retains China on the Priority Watch List .

Latest developments.

• Apple filed suit against OpenAI, Tang Tan, Chang Liu, and io Products in the Northern District of California, alleging a coordinated scheme to misappropriate hardware trade secrets through recruiting, former-employee conduct, and supplier deception (→ Apple sues OpenAI and two ex-employees for stealing trade secrets to build AI hardware, Apple sues OpenAI, alleging coordinated trade secret theft for AI hardware, Apple Sues OpenAI and Hardware Chief Tang Tan for Alleged Trade Secret Theft to Build Competing Devices, Apple Sues OpenAI for Trade Secret Theft Amid Hardware Partnership Rupture)
• Apple moved for a preliminary injunction seeking to bar OpenAI and named individuals from accessing, using, or disclosing alleged trade secrets during litigation (→ Apple asks court to block OpenAI from using alleged trade secrets, OpenAI Rejects Apple’s Injunction Bid in Trade-Secret Fight)
• OpenAI moved to dismiss, arguing Apple failed to identify protectable trade secrets or plausible misappropriation, and released private emails publicly as a counteroffensive (→ OpenAI seeks to dismiss Apple’s trade-secrets lawsuit over hardware hiring, Apple sues OpenAI over alleged trade-secret theft tied to AI devices)
• Northern District of California refuses to dismiss Flextronics v. Ricci, keeping alive fraud, breach of fiduciary duty, and trade secret misappropriation claims against a former deputy GC who secretly co-founded a startup that received favorable patent assignments (→ California Judge Keeps Flextronics IP-Theft Suit Against Former GC Deputy Alive)
• Fastcase v. Alexi Technologies reaches hearing stage in D.C. federal court; Fastcase seeks destruction of datasets and AI model weights trained on licensed case law, framing weights as infringing derivative works (→ Fastcase Sues Alexi Over Unauthorized AI Training Using Licensed Case Law)

Active questions and open splits.

• What constitutes "institutional knowledge" misappropriation in AI hardware recruiting? The Apple v. OpenAI complaint alleges OpenAI solicited confidential information through the interview process itself — before any employment relationship formed. Whether courts treat pre-hire information extraction as actionable misappropriation, and what evidence of institutional direction is required, is unsettled and will be the central doctrinal question in this litigation (→ Apple sues OpenAI and two ex-employees for stealing trade secrets to build AI hardware, Apple sues OpenAI, alleging coordinated trade secret theft for AI hardware).
• Will the Northern District grant a preliminary injunction restricting OpenAI's hardware development before trial? The injunction standard requires Apple to show likelihood of success on the merits and irreparable harm — both contested given OpenAI's denial of possession and its dismissal motion. A grant would materially constrain OpenAI's device roadmap; a denial signals the court's skepticism of Apple's threshold showing (→ Apple asks court to block OpenAI from using alleged trade secrets, OpenAI seeks to dismiss Apple’s trade-secrets lawsuit over hardware hiring).
• Can AI model weights be ordered destroyed as infringing derivative works of licensed training data? Fastcase v. Alexi is the first major test of whether courts will treat trained model weights as a derivative work subject to destruction — a remedy with industry-wide implications for any AI product built on licensed data (→ Fastcase Sues Alexi Over Unauthorized AI Training Using Licensed Case Law).
• Where exactly does the patent-disclosure bar fall under state UTSA variants? The Federal Circuit applied California's UTSA in International Medical Devices, but the analysis of what makes information "generally known" may differ across UTSA-adopting states and under the federal DTSA — clients with multi-jurisdiction portfolios need state-specific audits of any information disclosed in patent filings .
• How far does contractual tolling extend under the DTSA discovery rule? SkyBell holds that a reverse engineering ban in a bilateral agreement can prevent the limitations clock from starting — but the outer limits of that principle across one-sided NDAs, industry-standard confidentiality clauses, and post-termination obligations remain untested .
• What fiduciary duty exposure attaches when in-house IP counsel secretly co-founds a competing entity? Flextronics v. Ricci keeps alive the theory that an in-house attorney who arranges IP transactions benefiting an undisclosed personal interest faces simultaneous trade secret, fraud, and fiduciary breach liability — with downstream exposure in third-party patent disputes (→ California Judge Keeps Flextronics IP-Theft Suit Against Former GC Deputy Alive).
• Does China's new Trade Secrets Regulation materially change enforcement for foreign IP holders? USTR's Special 301 Report treats recent Chinese enforcement actions as insufficient despite the regulatory movement — the gap between formal legal reform and practical enforcement remains the operative question for clients with China-facing IP portfolios .

What to watch.

• The October 1 preliminary injunction hearing in Apple v. OpenAI — the court's ruling will signal the strength of Apple's threshold showing and set the tone for discovery disputes over OpenAI's internal hiring directives and communications (→ Apple asks court to block OpenAI from using alleged trade secrets, OpenAI seeks to dismiss Apple’s trade-secrets lawsuit over hardware hiring).
• The motion-to-dismiss ruling in Apple v. OpenAI — if granted, it eliminates the case before the injunction hearing; if denied, discovery on OpenAI's institutional knowledge of and direction to the alleged conduct begins (→ OpenAI seeks to dismiss Apple’s trade-secrets lawsuit over hardware hiring).
• The D.C. federal court's ruling in Fastcase v. Alexi on whether "internal use" restrictions in data licenses bar AI training applications — and whether model-weight destruction is an available remedy (→ Fastcase Sues Alexi Over Unauthorized AI Training Using Licensed Case Law).
• Whether the USTR's Section 301 investigation into China's Phase One compliance on technology transfer produces additional tariff actions or trade remedies affecting clients with China-facing IP portfolios .
• Appeals in the Tokyo Electron/TSMC criminal case — outcome will shape how Taiwan's National Security Act applies to future semiconductor trade secret prosecutions .
• Whether other AI hardware competitors facing talent competition with Apple or other incumbents accelerate trade secret audits and restrictive covenant programs in response to the Apple v. OpenAI complaint theory.
