It is certainly not trademark infringement, I can say that for sure -- no reasonable person would prompt ChatGPT to create a "new yorker style cartoon" and then think the result is produced by the actual cartoonist in mere seconds for their viewing pleasure. So there's no confusion in the marketplace.

The user could cause confusion in the marketplace of course, but that would be her doing, not the app's. Surely we can all agree that suing adobe illustrator for facilitating trademark infringement of logomarks and such would be silly?

It could be copyright infringement, which should drive home how absurd copyright is as a concept. Everyone's all up in arms about Anthropic reporting a user to the police today -- imagine if the thing they were reporting was that she had written a sacred symbol in her personal notebook...

There's also a narrower situation to consider, where the user describes something they "want"--implicitly to find--but the system generates a fraudulent one instead.

In that case ChatGPT would be committing a trademark violation, at least within a nation of laws rather than lobbying.
