Patent Law for Scientists, Inventors & Business Management is not a legal book for attorneys but rather is a practical discussion of critically important issues which cause patent applicants and those making the business decisions regarding patents to not infrequently lose patent rights. Too often brilliant inventive work coupled with a diligent well funded development effort leads to a patent which does not prevent third parties from using the invention without infringing or is invalid because of poor decisions during drafting and/or prosecution. This book educates the decision makers to the issues involved in obtaining valid patents with sufficiently broad scope to protect the assignee's investment. Whereas tax law is complex, patent law is not forgiving. With tax law often mistakes can be corrected by filing an amended return; with patent applications mistakes most often can not be corrected. It is critically important not to make mistakes in both drafting and prosecution of patent applications.
