Patent Infringement Question — 3D printing patented designs

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

3D printing patented designs. I've been dealing with this for about 15 months now and the situation isn't improving.

This involves content I created over the past 31 months. I do have documentation proving my ownership and timeline.

Has anyone been through something similar? What worked for you?

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

The biggest mistake people make in this situation is filing with the appropriate government agency. I'd recommend gathering evidence first 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.

I've dealt with this before.

What worked for me was filing with the appropriate government agency. It took 4-8 months but was worth it.
