Microsoft has a patent for opening a new window when you click a hyperlink
If you're a computer user (and let's face it, who isn't these days?), You know that when you click a hyperlink it often opens in a new window. This is such a common occurrence that you may not even notice it. No matter how small this action though, it still requires protection--patent protection.
Microsoft has a patent for opening a new window when you click a link. It was issued in 1985 and includes a great deal of technical jargon and description for such a simple task. So next time you click a link, know all the work that went into it.
