OpenAI denied Apple $AAPL's allegations of trade secret theft on Monday, arguing that the iPhone maker's own security policies and offboarding procedures were responsible for any improper access to its internal files, according to Reuters.

"This dispute is a mess of Apple's own making, and it is trying to blame everyone else," OpenAI said in a filing in U.S. District Court in San Jose, California. The company added that Apple "cannot use its own sloppy procedures to blame others for its own mess."
