OpenAI and Co-Defendants Move to Strike Apple Expert Evidence in High-Stakes Trade Secret Lawsuit
The legal battle lines between Apple Inc. and OpenAI have deepened significantly following a new filing submitted in federal court. OpenAI, alongside co-defendants io Products—the hardware firm founded by former Apple design chief Jony Ive—and former Apple employees Chang Liu and Tang Tan, has formally requested that the presiding court strike two crucial expert declarations and disregard a mass of newly introduced evidence submitted by Apple. This latest motion marks a fierce procedural escalation in a multi-pronged trade secret misappropriation lawsuit that threatens to expose the inner workings of consumer hardware development at some of the world’s most influential technology companies.
The core of the dispute centers on Apple’s aggressive push for a preliminary injunction. Apple is attempting to legally bar OpenAI and its partners from accessing, utilizing, disclosing, or soliciting proprietary Apple information and trade secrets while the broader litigation moves toward trial. According to Apple, such an order is vital to prevent its proprietary research from becoming permanently baked into OpenAI’s burgeoning hardware pipeline. However, the legal maneuverings have quickly devolved into a bitter dispute over procedural rules, fairness, and the admissibility of late-stage technical evidence.
Background Context and the Genesis of the Lawsuit
To understand the gravity of the current evidentiary dispute, one must examine the origins of the litigation itself. The conflict broke into the public eye when Apple filed a sweeping trade secret theft lawsuit against OpenAI, io Products, and former insiders Chang Liu and Tang Tan. The complaint alleges a targeted breach of trust and corporate espionage, asserting that individuals who once helped shape iconic Apple products pivoted to a competitor, taking invaluable institutional knowledge and confidential technical documents with them.
Specifically, Apple has accused Chang Liu of accessing highly sensitive engineering files after his departure from the Cupertino-based tech giant. Concurrently, the company has alleged that Tang Tan leveraged his remaining network inside Apple by soliciting confidential information from current employees who were participating in routine job interviews. Apple contends that this pilfered data was systematically routed to benefit OpenAI’s nascent consumer hardware initiatives, a market segment where OpenAI is widely reported to be building dedicated physical devices in partnership with Jony Ive’s design team.
For Apple, the protection of its intellectual property is an existential matter. The company invests tens of billions of dollars annually into research and development, securing its market dominance through closely guarded manufacturing techniques, advanced materials science, and proprietary power-management architectures. The alleged leak of these blueprints represents not just a breach of employment contracts, but a direct threat to Apple’s competitive edge in future hardware cycles.
Chronology of the Recent Legal Escalation
The procedural timeline leading up to the current motion reveals a rapid intensification of the courtroom warfare. The sequence of events highlights how quickly both sides are mobilizing technical experts and forensic teams to sway the court:
- Initial Complaint Filed: Apple formally initiates the trade secret lawsuit against OpenAI, io Products, Chang Liu, and Tang Tan, laying out detailed allegations of data exfiltration and illicit recruitment practices.
- Motion for Preliminary Injunction: Apple files a comprehensive motion asking the court to issue an immediate preliminary injunction to halt the alleged use and dissemination of its trade secrets during the pendency of the lawsuit.
- Defendants’ Opposition: OpenAI and the co-defendants submit their formal opposition briefs, arguing that Apple’s claims are unfounded, overly broad, and fail to meet the strict legal thresholds required for a preliminary injunction.
- Apple’s Reply Brief and Massive Evidence Drop: To counter the defense’s arguments, Apple files a robust reply brief supported by five extensive expert declarations totaling 126 pages, alongside 13 new evidentiary exhibits. The experts cited include Daniel Roffman, James Pooley, Dr. Ayman Fayed, Dr. Paul Hatch, and Dr. Jude Runge.
- The Defendants’ Strike Motion: In response to Apple’s evidence submission, OpenAI and the co-defendants file a new motion asking the court to strike multiple expert declarations and discard the newly introduced exhibits, citing procedural unfairness.
The Substance of Apple’s Evidence and the Defense Pushback
The recent flashpoint revolves around the 126 pages of expert testimony and accompanying exhibits introduced by Apple in its reply brief. Apple’s legal team enlisted a formidable roster of specialists to bolster its claims. Daniel Roffman provided digital forensics expertise; James Pooley contributed intellectual property law and trade secret protection insights; Dr. Ayman Fayed analyzed power-management trade secrets; Dr. Paul Hatch evaluated hardware engineering practices; and Dr. Jude Runge was brought in to testify on the specialized secrecy surrounding advanced metal-finishing processes.
Apple utilized these expert filings to argue that the defense’s opposition brief failed to dismantle the core trade secret allegations. Furthermore, the documents sought to establish rigorous baselines regarding Apple’s internal security practices, forensic traces left on Liu’s digital devices, and the inherent economic value of its power-management and material science methodologies.
OpenAI and the co-defendants immediately recognized the potency of these filings and launched a vigorous counter-offensive. In their new motion, the defendants accuse Apple of abusing the procedural purpose of a reply brief. They argue that Apple used the filing to smuggle in brand-new evidence, novel expert opinions, and supplementary analysis that should have been included in the original opening brief—a tactic they claim deprives the defense of a fair, reciprocal opportunity to cross-examine or adequately respond under the court’s scheduling orders.
"Apple submitted with its reply brief five new expert declarations (including one entirely new expert), totaling 126 pages, as well as numerous new exhibits," the defendants stated in their filing. "These declarations go far outside the scope of Apple’s opening brief and Defendants’ opposition, and in any event do not save Apple’s deficient motion."
Detailed Objections to Individual Experts
The defendants’ legal team dissects each of Apple’s expert submissions, pointing to specific procedural and substantive vulnerabilities:
- Dr. Jude Runge: The defense argues that Runge was introduced as an entirely novel expert late in the game, specifically to reinforce testimony that Apple had already submitted in its preliminary filings without justification for the late addition.
- Dr. Ayman Fayed: OpenAI asserts that Fayed offered brand-new technical opinions regarding power-management systems that were readily available and could easily have been incorporated into Apple’s initial motion.
- James Pooley: The defense contends that Pooley’s analysis relied heavily on an investigative report that was compiled only after Apple had already initiated its original motion, representing an improper post-hoc attempt to substantiate weak initial claims.
- Daniel Roffman: Roffman is accused of introducing evidence that was already in Apple’s possession prior to the initial lawsuit filing. Moreover, the defense claims Roffman presented specific communications involving Chang Liu completely out of context to manufacture an incriminating narrative.
As a remedy, OpenAI and the other defendants are formally petitioning the federal court to strike Roffman’s and Runge’s declarations entirely, along with Roffman’s five accompanying exhibits, while disregarding the broader array of late-introduced evidence.
However, the defense has also proposed a conditional alternative. In the event that the court decides to admit and consider Roffman’s declaration and exhibits despite the procedural objections, the defendants demand that the court simultaneously accept a new declaration filed by Chang Liu. This counter-declaration offers Liu’s own detailed, contextualized explanations for the specific messages and device activities that Apple has flagged as evidence of wrongdoing.
Broader Industry Impact and Strategic Implications
Beyond the immediate courtroom maneuvering, this legal confrontation carries profound implications for the technology sector, particularly as artificial intelligence companies race to merge sophisticated software models with proprietary physical hardware.
The intersection of AI and consumer electronics is widely viewed as the next major frontier for Silicon Valley. Companies like OpenAI, traditionally known for cloud-based large language models and software interfaces, recognize that controlling the hardware layer—from specialized silicon chips to custom enclosures and power-management systems—is essential for delivering seamless, ambient AI experiences. Partnering with visionary industrial designers like Jony Ive represents a cornerstone of this hardware ambitions.
Conversely, incumbent hardware titans like Apple view the aggressive talent poaching and cross-pollination of engineering talent as an existential threat. Apple’s protective posture over its supply chain, manufacturing techniques, and industrial design secrets is legendary. By pursuing litigation aggressively, Apple is sending a chilling message to both current employees and rival tech firms: attempts to migrate institutional knowledge across company lines will be met with immediate and maximum legal force.
From a broader legal perspective, the judge’s upcoming ruling on the motion to strike will set a critical precedent for how procedural rules regarding reply briefs and expert testimony are enforced in complex intellectual property disputes. If the court sides with OpenAI, it will reinforce strict limitations on expanding the evidentiary scope late in briefing cycles. If the court sides with Apple, it may signal a judicial willingness to accommodate expansive technical forensics when dealing with sophisticated corporate espionage and trade secret allegations.
As the litigation progresses, all eyes remain fixed on the federal docket for the court’s decision on the preliminary injunction and the admissibility of the contested expert declarations. The outcome will not only dictate the legal boundaries of the current lawsuit but could fundamentally shape how artificial intelligence pioneers and traditional hardware giants interact, compete, and share talent in the years to come.
