I noticed in a screenshot that the COPYING etc. files have a ® in their icon. That’s a registered trademark sign, not a copyright sign and as a lawyer it bugs me a lot.

I strongly suggest that we either use either the © sign in those icons, or if we really want to point out that those files are not just about copyright, but maybe even patents and trademarks, use the § sign.
But otherwise I like the icon itself :D
