...and the Apache 2.0 license belongs to a short list of licenses that have been extensively reviewed and can be trusted.
Every time someone comes up with a new license, the review work must be redone to ensure it respects the philosophy of Open Source. Which is why I prefer project published under well-known licenses (GPL2/3, LGPL, Apache, Mozilla, BSD, ...).
BSD is generally viewed to have an implied patent license. The patent file is usually there to give you a different set of rights than you would have gotten, be it good or bad (and i've seen both :P)
