Identifying Inventions in the Public Domain

This guide aims to assist researchers, inventors and entrepreneurs in determining whether specific inventions are protected by enforceable patents or may be in the public domain, by teaching a three-stage process for searching and analyzing published patent documents using the tools of freedom to operate determination. Designed for self-study, the guide has easy-to-follow training modules that take the reader through the process step by step, including with the help of useful checklists and other tools.
