Hey Alex, this isn't legal advice (and it's based on US law anyway), but
the way I understand it is that the design files and the idea embodied in
the design are different.
As long as you create your own design files from scratch you don't have to
worry about copyright.
Whatever you physically make is subject to patent law. It's possible for
anyone with a patent similar to what you build to sue you for infringement
and make you defend yourself in court. You can get around any patents they
might have just by building something slightly different, however, if they
sue you then you'll still have to spent time and money in court proving
that you didn't infringe (or settle before it gets to court).
It's unlikely that any of your projects will be so successful that they'll
attract the attention of a patent holder. Even if they do notice you, they
might decide what you're doing isn't a problem (for a variety of reasons).
In the unlikely case a patent holder does take legal action the most likely
first step is some kind of stop-doing-that letter. One of the strengths of
open source hardware is speed and flexibility, so you can just stop selling
that thing, or change the design so that it no longer infringes. If it's a
stable design that's selling well then you might just reach an agreement to
license the patent so you'd just pay the patent holder a fee for each unit.
Actually going to court is a last resort that you are unlikely to end up
choosing. You'd probably only do it if you get some outside agency to
defend the case pro bono. If it's a really interesting or high profile or
legally significant case then you've got a chance of getting an ally like
Keep in mind that the open source hardware definition doesn't allow you to
technically call your thing open source if you include a noncommercial
clause in your license. That means that anybody likely in a position to sue
you also probably has the option to just clone your thing and sell it
So the potential futures are a lot more complicated than just getting
dragged into court. That's a good thing :) Hell, if somebody does start
giving you trouble you might even be able to get the OSHW community to
shame them into backing down.
