OpenAI Fires Back at Apple Lawsuit with Employee Chat Logs

OpenAI has publicly challenged Apple’s trade secret lawsuit, releasing chat logs that suggest Apple employees themselves sought technical assistance from their former colleague, Chang Liu, after his departure to OpenAI. The move comes as OpenAI faces allegations from Apple of systematic trade secret theft and encouraging employees to abscond with proprietary information during their notice periods. This counter-narrative from OpenAI paints Apple’s legal action as both “sloppy and unnecessarily aggressive,” shifting focus onto Apple’s internal access management practices.

Key Developments

• OpenAI released chat logs indicating Apple employees contacted former colleague Chang Liu for technical information after his departure.
• Apple’s lawsuit accuses OpenAI of systematic trade secret theft and encouraging departing employees to steal confidential files.
• Chat logs show Apple employees repeatedly reached out to Liu for technical assessments and help locating internal files, even adding him to a group chat.
• OpenAI attributes this to “residual access,” a problem it claims stems from Apple’s poor access management.
• Apple’s legal team reportedly made errors in initial contact with OpenAI, confusing Asian last names and claiming phone calls that OpenAI denies.

What Happened

OpenAI recently pushed back against Apple’s federal lawsuit in California, which alleges the systematic theft of trade secrets. Apple’s complaint specifically targets former engineer Chang Liu, claiming he improperly accessed confidential information after joining OpenAI, and broadly accuses OpenAI of encouraging new hires to steal proprietary data. In response, OpenAI published chat messages that it asserts demonstrate Apple’s own employees repeatedly contacted Liu for technical guidance and internal file locations following his departure.

According to the released communications, Liu’s final day at Apple was January 22, 2026. On that very day and in the subsequent weeks, Apple staff members continued to reach out to him with technical inquiries. A message from January 27, 2026, shows an Apple employee explicitly requesting Liu’s technical assessment, stating, “Of course, I could ask several folks, but you are the best. Even if you don’t work here anymore.” Liu reportedly provided details about internal Apple decisions. Further exchanges included requests for schematics on February 14, 2026, and his addition to an Apple group chat on March 5, where he directed employees to internal folders and contacts before ending the conversation himself, noting its irregularity. OpenAI argues these instances highlight “residual access” issues at Apple, stemming from inadequate access management.

Why It Matters

This public rebuttal by OpenAI introduces a significant twist into the high-stakes legal battle with Apple. By presenting evidence of Apple employees contacting a former colleague for internal information, OpenAI attempts to reframe the narrative, suggesting that any alleged “improper access” might have been facilitated, albeit unintentionally, by Apple’s own operational shortcomings. This defense strategy could complicate Apple’s claims of systematic theft and encouragement of intellectual property breaches, potentially shifting scrutiny onto corporate security protocols and employee offboarding processes within large technology firms. The outcome of this legal dispute could set precedents for how companies manage departing employees and protect their intellectual property in a highly competitive AI talent market.

Analysis

OpenAI’s strategic release of chat logs serves as a potent counter-narrative in its legal skirmish with Apple. The core of OpenAI’s argument hinges on the concept of “residual access,” suggesting that Apple’s own internal procedures, or lack thereof, contributed to the very situation it now alleges as theft. This tactic aims to undermine Apple’s portrayal of Chang Liu as a rogue actor or OpenAI as an instigator of IP theft, instead painting a picture of a former employee simply assisting colleagues who were struggling to navigate internal systems post-departure.

Furthermore, OpenAI’s claims regarding Apple’s initial legal missteps—such as confusing Asian last names in correspondence and alleging phone calls that never occurred—add another layer of complexity. These alleged errors, if substantiated, could weaken Apple’s credibility in court by suggesting a lack of diligence in their preliminary investigation and communication. While these points do not directly refute Apple’s broader allegations concerning the potential theft of trade secrets by other former employees or OpenAI’s alleged encouragement of such actions, they certainly cast doubt on the thoroughness and precision of Apple’s case construction. The legal battle extends beyond Liu, encompassing over 400 former Apple employees now at OpenAI and linking to OpenAI’s hardware ambitions with io Products, co-founded by Jony Ive. The defense of Tang Tan, another former Apple executive, further illustrates OpenAI’s intent to vigorously contest Apple’s wide-ranging accusations.

Key Takeaways

• OpenAI is challenging Apple’s trade secret lawsuit with evidence suggesting Apple employees sought technical help from a former colleague now at OpenAI.
• The defense highlights “residual access” as a potential issue stemming from Apple’s internal access management.
• OpenAI also points to alleged errors by Apple’s legal team in initial communications, including misidentified contacts.
• The lawsuit involves broader allegations concerning over 400 former Apple employees now working at OpenAI and OpenAI’s hardware ambitions.
• This legal battle underscores the intense competition for talent and intellectual property in the rapidly expanding AI sector.
