Didn't they sue someone over the use of the word "Book" (teachersbook) or something like that? This was a common phrase to apply to a year book. This kind of stuff is just beyond me...nobody should be able to own common words or letters.
Soon enough each individual letter will be owned and anybody caught using any of them will have their pants sued off of them. Aside from the 24 letters, I wonder how far into extended ASCII (or worse yet UNICODE) they'll get. I claim umlaut.
Trying to be happy is like trying to build a machine for which the only specification is that it should run noiselessly.
