I wouldn't count Twitter out just yet.<p>All three of the other pending marks are based on Twitter's own earlier (unregistered) use of 'Tweet'. So Twitter might be able to argue <i>those</i> should be rejected based on their earlier common-law usage.<p>Or, they could buy off those three applications.<p>Or, a combination of both. ("Do you folks want to make us your enemy, and take a chance that your registration will be rejected based on our earlier creation of the 'Tweet' term, or take this bag of money/stock/thanks? Your choice, tiny companies dependent on our ecosystem!")
