Who Owns Claude AI Output? Commercial Use Rights

I'm dealing with a situation and need some guidance.

NFT of someone else's art. I've been dealing with this for about 16 months now and the situation isn't improving.

This involves content I created over the past 6 months. I do have documentation proving my ownership and timeline.

Do I have a strong case? What should my next steps be?

I work in this industry and unfortunately this is very common. The good news is that when people actually push back with legal representation, companies usually settle.

Following this thread — I'm in a very similar situation. Would love to hear how it turns out.

I've seen this play out several times in my field.

The biggest mistake people make in this situation is having everything documented. I'd recommend keeping a detailed timeline instead.
