Invention Analysis and Claiming: A Patent Lawyer's Guide, Second Edition, presents a comprehensive approach to analyzing inventions and capturing them in a sophisticated set of patent claims. A central theme is the importance of using the problem-solution paradigm to identify the "inventive concept" before the claim-drafting begins. The book's teachings are grounded in "old school" principles of patent practice that, before now, have been learned only on the job from supervisors and mentors. Questions at the end of each chapter have been added to: -Confirm the understanding of the principles presented; -Explore the jurisprudential and practical implications of those principles; and -Try out the invention analysis and claim drafting skills taught in the chapter.
