Man, I have to get into this patent thing! Sure, it only lasts 20 years but that's 20 years of $$$ coming to me!


Edit: I feel like there's got to be "prior art" for this. I know keyboards were being manufactured with page up and page down buttons before 2005.
Someone would have to take Microsoft to court to get the patent revoked. That's pretty much how the patent office works: get anything you want, and let the courts decide what is and what is not acceptable.
Then they should pool their resources together and hire the best lawyer.Individuals and small businesses lose. Lawyers win.
