Apple Says OpenAI Added New Arguments in Trade Secrets Case
Apple filed a response arguing OpenAI and other defendants introduced new arguments and testimony in their objection filing.
Apple filed a response on October 5, 2026, arguing that OpenAI and other defendants went beyond objecting to new evidence in the trade secrets case and introduced new arguments and testimony of their own, according to 9to5mac.com.
Apple singled out a new declaration from Chang Liu, calling it "the most egregious overreach" in the defendants' filing.
The company argued that the court should consider the full record rather than strike any of Apple's reply evidence.
The court is scheduled to hear arguments on Apple's preliminary injunction request on October 14.
