Hypothetical question

I've been trying to resolve this on my own but I'm stuck.

reverse engineering software. I've been dealing with this for about 5 months 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.

Am I overthinking this or is this a real legal issue worth pursuing?

Illustrative response

Just want to point out — the statute of limitations might be a factor here. In some states it's as short as 1-2 years. Don't sit on this too long.
