Roland Henss 'Capitalis Pirata' font has gotten Plazm font factory their very own cease and desist letter from McDonalds fat factory, McDonalds doesn't like the "M" which looks a lot like theirs. Actually that was the idea,
"By placing corporate icons into the form of an alphabet, Henss challenges the notion of ownership of letterforms. Since a copyright cannot be placed on the alphabet itself, this typeface raises issues about the boundaries of ownership and the proprietary nature of letterforms in the public domain."
An M-free version of the font can be downloaded at Plazm.
If I ruled design is a little flash game that lets you take on the big men of Bauhaus, the logo king Paul Rand and the typographers with mad skillz - just remember to duck!
UPDATE: on a related note - There was once a font aptly named McLawsuit - alas that has been C&Deed as well. On the same site you can pick up Munificent based on the San Fran MUNI logo.
