Hypothetical question

Looking for advice on a legal issue. Here's what happened.

open source code in commercial product. I've been dealing with this for about 15 weeks now and the situation isn't improving.

This involves content I created over the past 34 months. I do not have documentation proving my ownership and timeline.

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

Illustrative response

Small claims court update: filed my case, hearing is in 6 weeks. The filing fee was only $75 and I don't need a lawyer. The court clerk was actually very helpful in explaining the process. If your claim is under $10K (or $12.5K in some states), small claims is the way to go.
