Apple is disputing the interference of the U.S. Justice Department in a copyright suit against software maker Corellium as questions arise as to why the federal government is now involved in the case.

The Department of Justice has now intervened in the case asking Apple to delay its request for a deposition of Corellium cofounder Chris Wade, and inquiring to what evidence Apple is planning on presenting before its lawyers question Wade.

One of Apple’s biggest foes in the courtroom, Corellium, is making it possible for iPhone users to install Google’s Android operating system on Apple’s devices.

Corellium released the first public beta build of its Android for iPhone software today called Project Sandcastle. The software currently only works on a couple of iPhones but if you’ve ever wondered what it’d be like to have Android 10 running on Apple hardware, this is the closest you’re going to get.

Apple has reportedly subpoenaed Santander Bank and $50 billion intelligence contractor L3Harris Technologies as part of its ongoing battle with cybersecurity startup Corellium.

Apple wants to know how both groups are using Corellium’s software. This software lets companies run virtual versions of iOS for security and functionality testing.

The makers of a product allowing users to run iOS firmware in a web browser have hit back at Apple.

Apple sued the former iPhone jailbreakers behind Corellium in August. However, Corellium counters Apple’s claims of IP theft by saying that it is performing a crucial function for security researchers.

Apple is suing Corellium, a company founded by former iPhone jailbreakers whose product lets users run iOS firmware in a web browser.

“There is no basis for Corellium to be selling a product that allows the creation of avowedly perfect replicas of Apple’s devices to anyone willing to pay,” Apple’s lawyers argue in the suit.
