> You lose a trademark if it becomes generic

And this is my biggest gripe with products from well-known companies that use already generic terms like "Apple", "Word", "X", or "Inkwell". I understand claiming exclusivity of words like "Microsoft Word", but not for the word "Word" itself.

Yeah where does it become a violation. Like if i wrote an app called wordsmith, and it does basically what word does, let you edit documents, is that really a trademark violation? Because i used the word word?
