Apple Loses Copyright Claims in Lawsuit Against Corellium

Corellium, a mobile device company that supports iOS, this week won a significant victory in its legal battle against Apple. Apple last year sued Corellium for copyright infringement because the Corellium software is designed to replicate iOS to allow security researchers to locate bugs and security flaws.

According to The Washington Post, a Florida judge threw out Apple's claims that Corellium had violated copyright law with its software. The judge said that Corellium successfully demonstrated that it operates under fair use terms.

"Weighing all the necessary factors, the Court finds that Corellium has met its burden of establishing fair use," Judge Smith wrote Tuesday's order. "Thus, its use of iOS in connection with the Corellium Product is permissible."

In its lawsuit, Apple said that Corellium illegally replicated the operating system and applications that run on the iPhone and iPad. "Corellium has simply copied everything: the code, the graphical user interface, the icons - all of it, in exacting detail," Apple said in the original filing.

Corellium's software does indeed create digital replicas of iOS, iTunes, and user interface elements available on a web-based platform or custom platform built by Corellium, with the software posed as an exact copy of iOS to allow security researchers to locate bugs. Corellium argued that its software helps Apple by making it easier for security researchers to find flaws and has also accused Apple of using the lawsuit to "crack down on jailbreaking."

Corellium claimed that Apple's code in its product is "fair use," which the judge in the case agreed with. Apple has also said that Corellium circumvented Apple's security measures to create its software and violated the Digital Millennium Copyright Act, and that claim has not been tossed out. Apple has not yet commented on the decision.

As an alternative to Corellium, Apple launched a Security Device Research Program to give vetted researchers access to specially-configured iPhones that are less locked down than consumer devices with the aim of helping researchers locate bugs in iOS. Apple in late December began sending out the first of these research iPhones.

Apple's $634 Million Apple Watch Patent Bill Just Got Even Bigger

Tuesday October 6, 2026 6:09 am PDT by
Apple's $634 million patent loss to medical technology company Masimo has just gotten even bigger, after a federal judge ordered Apple to pay an additional $184 million in interest on what it owes (via Bloomberg Law). The ruling takes Apple's bill to around $818 million, but that doesn't include any post-judgment interest continuing to accrue until the judgment is paid. Judge James Selna ...

I fail to see the fair use of just copying everything. Copyright doesn’t make any sense if anyone can just copy a work.

As an IP attorney, I think this is a good ruling. Fair use is often not considered by internet companies so the public thinks it's not real. (For instance, posting a 15 second clip of your child dancing to music is fair use of the music, but You Tube will often take it down).

Reverse engineering is fair use.

Copyright protects creative expression, not facts or algorithms. The less creativity the less the protection. Thus, code is mostly the province of patents, not copyrights, and the court shouldn't give wide copyright protection.

This ruling will open a whole proverbial can of worms. If this one company can copy Apple's code, that means others can as well.

The ruling said nothing about lying. Just because Apple lost, that doesn't mean they lied. You would have to take the article and wrap it in the shape of a pretzel to come up with the conclusion you did.
