I'm not sure how common design patents are though. Relative to copyright, patents are much shorter duration and much more expensive and time-consuming to get whereas copyrights just happen (though you may want to register for greater protection--but that's still cheap and easy.

Yeah, agreed that it seems unlikely to be a problem for most typefaces. I just think it's a bit misleading to suggest it's guaranteed to unburden the typeface of any and all 'intellectual property' protections ("In the US, you can literally go and vectorize any font in the world and do whatever you want with it").

And, of course, I can sue you for copying my typeface even if I'll probably lose in court and you probably don't want to spend at least 5 figures in lawyers to defend your open source typeface design.
