> Works predominantly generated by AI without meaningful human authorship are not eligible for copyright protection
Note the word "predominantly", and the discussion that follows in the article about what the courts and the copyright office said.
Nor does it give a single answer.
Mere prompting is still not enough for copyright, and the problem is unsolved on how much contribution a human needs to make to the generated code.
In the case for generated images copyright has been assigned only to the human-modified parts.
Even worse, it will be slightly different in other nations.
The only one that accepts copyright for the unchanged output of a prompt is China.
There are far more characters protected by copyright than trademark.
Plus what if Anna Karenina was GPL?
AI to review - shallow minutia and bikeshedding
AI to edit - wrote duplicated functions that already existed
AI to test - special casing and disabling code to pass the narrow tests it wrote
AI report - "Everything looks good, ship it!"
How much code do you need to change in order for it to be original? One line? 10%? More than 50%?
That's arbitrary and quite unproductive convo to be honest.
Yeah but that’s what the legal system ostensibly does. Splitting fine hairs over whether a derived work is “transformative” is something lawyers and judges have been arguing and deciding for centuries. Just because it’s hard to define a bright red line, doesn’t mean the decision is arbitrary. Courts will mull over whether a dotted quarter note on the fourth bar of a melody constitutes an independent work all day long. It seems absurd, but deciding blurry lines are what courts are built to handle.
That makes no sense because what if you refactor your code ad infinitum using AI? You spin up a working implementation, then read through the code, catalog the changes like interface, docs, code quality and patterns and delegate to the AI to write what you would.
It's 100% AI code and it's 100% human code. That distinction is what's counterproductive.
As the article says in the Tl;DR at the top the code may be contaminated by open source licenses
> Agentic coding tools like Claude Code, Cursor, and Codex generate code that may be uncopyrightable, owned by your employer, or contaminated by open source licenses you cannot see
That's not how copyright works. The modified version is derivative. You can't just take the Linux kernel, make some changes, and slap a new license on it.
