US Patent Case Studies, 2005

Since its establishment in 1982, the CAFC (United States Court of Appeals for the Federal Circuit) has passed judgments that serve as a guideline in the field of legal interpretation and practices. Their judgments are highly informative in regards to patent and trademark examination as the CAFC handles appeals from the United States Patent and Trademark Office. This text is a continuation of CAFC Patent Case Study (1) supplemented with expert commentary and introduces the most crucial CAFC judgments in recent years, encompassing all aspects of patent litigation such as probability of patent litigation, the Doctrine of Equivalents, prosecution history estoppel, patent rights interpretation, patent validity, enforceability of rights, and procedural issues.
