Apple escalates claims against OpenAI, alleging evidence destruction in trade-secrets fight

Apple has renewed its push in its legal battle against OpenAI, telling a court that OpenAI is “destroying” evidence relevant to Apple’s trade-secrets allegations, according to a report published by Yahoo Finance on Aug. 31, 2026.

In the filing described in the report, Apple argued that OpenAI’s conduct is interfering with the ability to preserve and review material connected to the case. Apple framed the issue as not just a dispute over documents, but as an active problem in the litigation record itself.

The same report says Apple’s filing also involved former iPhone engineer Chang Liu, who is described as having “not only downloaded” confidential information. The report does not provide additional specifics in the material available here about what Liu downloaded, how the information was used, or what that information was meant to enable.

Apple’s trade-secrets case centers on claims of misappropriation, with Apple asserting that confidential information was taken or mishandled in a way that harmed Apple. At this stage, the filing described by Yahoo Finance is focused on alleged evidence-related conduct by OpenAI, as well as Apple’s broader assertions regarding the handling of confidential material by individuals tied to the dispute.

For Apple, litigation involving trade secrets is high-stakes because the company typically relies on tightly controlled product and engineering information, including internal processes, designs, and know-how that can be difficult to recreate. In disputes like this, companies often emphasize the importance of document preservation, because what is missing or altered can shape what can be proven in court.

The report does not specify what evidence Apple claims was destroyed, whether Apple requested particular remedies, or how OpenAI responded to the allegations. It also does not describe any court orders, deadlines, or evidentiary rulings tied to the new accusation.

What remains unclear from the available record is the evidentiary foundation for Apple’s “destruction” allegation, such as what communications, system logs, or other indicators Apple says support its claims. The filing also is not summarized here in enough detail to determine whether the alleged conduct occurred during an active litigation hold, during a period of discovery, or as part of other internal document handling.

Going forward, the key issue for observers is whether the court will require additional discovery steps or sanctions-related measures if it finds Apple’s preservation concerns credible. Another watch item is how the litigation record will address the allegations about Chang Liu and any alleged downloads of confidential information, including how those claims are supported with documents and testimony.
