Key point

In connection with its trade secret infringement lawsuit against OpenAI, Apple sent legal letters ordering the preservation of evidence to dozens of former Apple employees who moved to OpenAI.

Details

Apple's trade secret infringement lawsuit against OpenAI is expanding. Apple recently sent legal letters to about 40 former employees who moved to OpenAI, ordering them to preserve related documents and communication records.

Through this lawsuit, Apple claims that OpenAI systematically stole confidential information related to hardware engineering and product development. Notably, it has been reported that Tang Tan (OpenAI's Chief Hardware Officer) and Chang Liu, who were key Apple personnel, are among the more than 400 former Apple employees currently working at OpenAI.

Apple is seeking the following measures:

  • An injunction to stop OpenAI from using Apple's information in its AI hardware development process
  • Damages for trade secret infringement
  • Individual lawsuits against Tang Tan and Chang Liu for breach of contract

In response, OpenAI has completely denied the allegations, stating that it could not find any evidence supporting the validity of the lawsuit's claims.
