Query: Great title but it's a very disappointing book.

I had great expectations when I ordered this book based on it's title - but it quickly disappointed. On page 39 under the heading PATENTS it explains that "A patent is a time-limited, exclusive right that is granted for an invention" duh? I think I already KNEW THAT! You get the picture? It's a very elementary book - you'd have to be absolutely green not to know most of the stuff in this book. Except for the fact that half of it is full of legal blurb about Geneva convention, Rome convention, Nairobi(?) Treaty and loads of useless information. Nothing dynamic about how companies with a decent patent portfolio can ACTUALLY capitalise or profit as the title suggests. A useless book.
