Review: Thesaurus of Claim Construction
Thesaurus of Claim Construction, by Robert C. Kahrl and Stuart B. Soffer, 2011 Oxford University Press, is an outstanding reference tool for patent practitioners. The publisher was kind enough to send me a review copy and I have used it regularly in the course of preparing patent applications and responding to patent office actions. The interpretation of a single word can be the difference between a strong patent and a weak one, between a huge damage award and no damages, so it is important to get every word right. When I am uncertain how a word might be interpreted, I turn to this comprehensive resource to pull up relevant cases where courts have interpreted similar language. I love both the coverage (~1000 pages) and the ease of use. Definitely nice to have, if a bit pricey. I also have concerns about how the book will age, as new court decisions come out. It seems like supplements would be required, which there are not, as far as I know.
