SOS: 3D printing patented designs

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

3D printing patented designs. I've been dealing with this for about 4 months now and the situation isn't improving.

This involves software/code I developed over the past 33 months. I do not have documentation proving my ownership and timeline.

What are my legal options here? Is it worth pursuing?

Following this thread — Bookmarking this. Dealing with almost the exact same thing.

I've dealt with this before.

In my case, it took about 3-6 months to resolve. The key was having everything documented.

So this is more common than people think.

The trap most people fall into is escalating to a supervisor/manager. I'd recommend following the formal complaint procedure instead.

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.
