First of all, this isn’t a settled issue. Some people would argue Zarya of the Dawn is owned by everyone who created a copyrighted work that was used to train Midjourney. I hope these people are wrong, but it’s a legal grey area right now.

The copyright office is not an authoritative source on legal issues. For that you need to find a criminal copyright infringement court case where someone with good lawyers enters a not guilty plea and the case goes all the way through to a final verdict.

Second - if your code is so simple that you can just ask an LLM to write the entire thing for you… then who cares if it’s copyrighted? Anyone else in the world can just ask the LLM to write it separately for them. Why would they risk a lawsuit by copying your work? They’ll get a better end product by using the latest version of the LLM anyway.

Under the Copyright Act, a compilation is a “work formed by the collection and assembling of preexisting materials or of data that are selected, coordinated, or arranged in such a way that the resulting work as a whole constitutes an original work of authorship. The term compilation includes collective works” 17 U.S.C. 101. This gives the compilation a separate copyright from any of the individual pieces within it. An author who creates a compilation owns the copyright of the compilation but not of the component parts.
