A few more riffs on trademarks:
a. a word in a foreign language makes a poor trademark in terms of defense (see Halushka noodle). So do superlatives. Ridiculous attempts to trademark ordinary language, as Uri points us to, are silly as well. The best trademarks have nothing at all to do with what you’re attempting to describe.
b. a neologism (a brand-new word that describes something that always needed a word to describe it) is a great trademark, in the short run anyway, and it comes with a lot of google juice. Words like ‘warez’ and ‘ideavirus’ are worth a great deal once they spread. Though you may have trouble defending it later (‘Xerox’).
c. remember, there are no official trademark police. A trademark is a license to sue, not a license to win. It all depends on how you want to spend your time and money.
