U.S. patent office cancels Redskins trademark registration, says name is disparaging

[agzg]

Wouldn't a determination that the C in NAACP was disparaging come out of someone filing a complaint with the patent office, presumably someone affected by that disparagement? I mean, it's not like the patent office just woke up yesterday and decided "oh hay, Redskins is offensive! Let's look up all their trademarks and tell them to suck it!" Someone filed a complaint.

Also, general point: 1988 was 26 years ago. That's hardly "out of the blue."
