These clowns - Timothy Sellers, Heather Grantham, and Joshua Dersch from Microsoft - are one of two things: deeply stupid, or completely devoid of any sense of ethics. How else to explain this completely bogus patent:

A method and system in a document viewer for scrolling a substantially exact increment in a document, such as one page, regardless of whether the zoom is such that some, all or one page is currently being viewed. In one implementation, pressing a Page Down or Page Up keyboard key/button allows a user to begin at any starting vertical location within a page, and navigate to that same location on the next or previous page. For example, if a user is viewing a page starting in a viewing area from the middle of that page and ending at the bottom, a Page Down command will cause the next page to be shown in the viewing area starting at the middle of the next page and ending at the bottom of the next page. Similar behavior occurs when there is more than one column of pages being displayed in a row.

They must be so proud to have their names on a patent granted in 2008 for a configurable page up and page down. What's next for this team of geniuses at Microsoft - the pixel?

Mind you, I should throw a few rocks at the patent office moron who granted the patent. I wonder - was he using a keyboard when he stamped "yes" on it?
