"For over 25 years, I have relied on Prof. Chisum's treatise as THE essential tool for answering every conceivable patent law question. I have been repeatedly amazed by both the range and the depth of the subject matter contained in his work. No matter how arcane the patent law question, Prof. Chisum provides the answer. Frankly, could not do my job without the benefit of his books, both the main volumes and his amazing Federal Circuit Guide."
