This book focuses on a comparative study of claim interpretation in the United States and China and addresses the question of whether the law of claim interpretation functions similarly or differently in the two countries. By an in-depth analysis of claim interpretation, this book provides researchers and legal professionals with a perspective to understand the practice of protecting patents in the U.S. and Chinese courts. 
To examine the law in the United States, this book mainly focuses on cases and statutes, while using literature such as treatises, journal articles, and books as secondary references. When examining the law in China, in addition to statutes, cases, and secondary references, this book also covers judicial interpretation, which is an important primary authority in the Chinese legal system. This is not only the first book to cover patent claim interpretation in China, but also the only book which looks into the details of judicial opinions of Chinese courts in patent disputes.
