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 12 weeks now and the situation isn't improving.

This involves original creative work over the past 9 months. I do not have documentation proving my ownership and timeline.

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

I've handled similar cases. Here's my take on the legal issues.

The practical consideration here is cost vs. potential recovery. For disputes under $10K, small claims court is often the best route.
