The patent offices are likely just used to seeing a steady stream of crap from Apple that is so wacky they just accept it as part of their
charm whether from a dead man or not. I wouldn't be surprised if Apple has partners (or their own) planted in the same building to coincidentally wine and dine the patent office execs regularly like lobbyists. There is obviously a well paid set of folks that just file random crap patents from Apple constantly in a hope something, anything hits, and since it's Apple they simply cannot and will not be ignored.
I really can't say I blame them either, look at the lines of patent trolls lined up in West Texas every year to sue them. State of the nation...
I do have to wonder if someone went back to criticize the fact a dead man is the most inventive corpse since 2Pac and Biggie if the patents could be invalidated as superfluous. Yeah right, it's Apple.
