Would this shape be covered by copyright? Or is it an uncopyrightable mathematical idea? For example, would it be possible for various floor tile suppliers to cut their material in this shape?

Penrose Tiles were patented and used successfully to stop a manufacturer from using them. So this is patentable (and likely already filed I'd guess). https://morris.cymru/en/2009/01/penroses-patent-and-the-battle-of-the-tissue-tiles-contains-mathematics/ https://morris.cymru/en/2009/01/penroses-patent-and-the-batt...

I don't think a copyright would make sense, in general you can't copyright just a shape. It has to be part of something with creative input. You could trademark it as part of a logo, but that does not seem to apply here (there's no business trying to use it as their mark). Maybe a design patent, or normal patent? (I'm not a lawyer) Another complication if they tried to get others not to use it: I believe they found a whole family of shapes, not just one shape. Even if they can keep one, seems like it'd be harder to keep them all to themselves. (not sure they've shown any desire to prevent others from using them either, this is just hypothetical).

    Yeah that's a good point that I'm not really able to resolve (my knowledge of IP law tends to end not much past what applies to software). I _think_ it wouldn't really count if it's not visible in the output though, the shape itself.

  Perhaps you're right - Penrose tiles were protected by patent and trademark. Wikipedia treats them as copyright-free.

  A basic rule is that you cannot patent a mathematical formula. But what you can patent is a novel way of "doing" anything. So if this is a novel way of covering your floor then my guess you could at least try to patent it.
