After reading Karen’s book, and using some of her tips on the USPTO.gov website, I know this book is going to save me money in attorney’s fees! It will definitely enable me to go into the attorney’s office with some basic knowledge, and avoid some of the charges for time normally spent for the attorney to explain the processes. I have been through the trademark process with attorneys. The Patent process seems a lot more complicated. This is not a quick read, nor is it a comprehensive guide. U.S. Patent Tools is more of a reference source which I expect to use repeatedly. I followed the author’s advice to open the website while reading, and was able to follow along with her narratives to navigate within the USPTO website. I learned several things that are already worth WAY more than the cost of this book! If you want help to better understand the patent process, and to be able to monitor your patent process, the cost of this book is a small price to pay for some help.
