As an user, I wholeheartedly agree. Also, I was not able to find any
patents with a similar name from a patent office other than the USPTO,
so it seems this would be a regional restriction.

Even funnier, SGI seems to have patented the same thing* twice with the
USPTO. (That certainly makes a statement about the USPTO, but it
probably doesn't have much legal effect, does it...)

(* the abstract is identical word by word, didn't read on after that)
