In the Thesaurus of Claim Construction, authors Robert Karhl and Stuart Soffer direct practitioners to the essential cases in which claim terms have previously been construed, and to the sources of the evidence used by past courts to construe the terms in dispute. This two-volume Second Edition is updated to include over 3,500 additional entries, some of which focus on Biotechnology, Pharmacology, and Cleantech. Ordinary Skill is now included as a topic.
