It's true. Futuremark (of 3DMark fame) has actually filed a Trademark application for the word pwnage, which you can read here.
At the outset, this is an utterly futile exercise as pwnage is so commonly used as to proffer no brand potential whatsoever to the pwner of the trademark. Plus, trademark law is sticky and claims can be implicitly declared through use. Precedence, if any is to be given, clearly lies with ROFLMAO productions, the lovable scamps behind the delightful show Pure Pwnage.
Funny thing about precedence, though, is that it doesn't always matter. In legal speak, big bastards can do big bastardly things to squash the idealistic little guys. This was the case with the popular internet messenger formerly-known-as Gaim.
I generally try to maintain more or less timeless themes in the comic so as to guarantee its immortality (did I mention modesty?), but the absurdity of this maneuver seemed to demand comic retribution.
