Yeah, one I really like for its fun-but-useful content is
THE ENTREPRENEUR'S GUIDE TO patents, copyrights, trademarks, trade secrets, & licensing by Jill Gilbert. It's a good read.
Ron, I do have to say that your book is truly informative and well-laid out. I started reading it to see if there was anything to critique, and I quickly found myself reading it to absorb every point.
I would highly recommend
The Inventor's Bible by Ron Docie to anyone. It has a great deal of valuable content all the way thru. There are bunch of sensible tips for every stage for the independent inventor, within every paragraph. Good section on tradeshows, also. It's a little too rough on US Patent Agents

, but overall, it's definitely a must have.
Another good little book for inventors is called
Patent Law and Practice by Herbert Schwartz. I'd have to warn you that this one is
beyond technical, because to doesn't even mention most of the common law behind the policies. It is written for judges who need the absolute skinny on patent law. So, if it's just a blur, then start off with a good casebook or two. Otherwise,
An Introduction to Patent Law by Janice Mueller is pretty good, and it's got a friendly alphabetic index in the back (
a la Patent It Yourself by David Pressman).
Cheers
