I had a thought that raised some questions. It was my “Litter Robot” that brought it to mind so I’m using that as my example here.

Litter Robot has patents on it’s method for sifting kitty litter (revolving tub).

Now obviously I can’t sell a product that uses that in any way, but it would be fairly easy to do some modeling, 3d print parts, and use something like an arduino for the control circuitry.

If I did this only for myself no one would know, but there likely wouldn’t be any legal challenge even if the company found out since there has been no monetary harm done.

What if after I made the models, I posted the plans as Open Source so others could DIY it on the cheap?

Would that be considered infringing on their patent?

Would Litter Robot have a civil case against me since the Open Source project could potentially be costing them customers?
