DMCA Takedown — 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?

Licensed attorney — a few thoughts. Here's my take on the legal issues.

There are several legal theories that could apply here. The strongest is probably 17 U.S.C. § 106, which requires showing substantially similar.

Before taking legal action, consider sending a formal demand letter. In many cases, this alone resolves the issue.

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

I've dealt with this before.

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

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

The biggest mistake people make in this situation 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.
