Not an IP lawyer, (those people are EXPENSIVE), It’s perhaps less about the idea than it is about the process to get there. And yes the patent office does make mistakes at times. It’s just expensive and hard to correct those mistakes because it generally takes a judge to do so. And I’m willing to bet this patent is valid in the EU also due reciprocity agreements and trade deals. It would take an EU judge to invalidate the patent, which would cost as much as doing so in the US.

One thing that I have learned over the years is that no patent is actually really valid until a judge bangs a gavel and says yea or nay to the patent, (I’ve held a couple). Until then, it pretty much just a piece of ass-wipe paper you can wavy around and hopefully scare off others that don’t have the money or want to spend the money to challenge the patent.

I would say we should just implement it in open source software, anonymously, and let them kick rocks.

If they want to press the issue they can go after whoever-it-is for their “slice” of the infringing revenue generated, which is zero dollars and zero cents. If they want to shut down a project we can just pack it up and pop up elsewhere under a new one. Fuck 'em.

It is obviously already possible on a technical level, at least with varying degrees of ease, using modifications to existing tools. Sefan from CNC Kitchen posted a video a while ago where he managed to pull off and test several prints using brick layered perimeters.
