NPA International, Inc. is the well-established U.S. Office of China Sinda Intellectual Property Limited, a leading, privately-owned law firm in China entitled to practice intellectual property law. Our practice encompasses preparation and prosecution of applications for patents, trademarks, copyrights, and related counseling as well as judicial proceedings. 

By 2000, China Sinda had grown to be one of the largest private IP law firms in China with over 200 attorneys and supporting staff in the Beijing head office. In addition, our firm has been supported by an accomplished panel of counsels with over thirty years of patent and/or trademark experience; some of them are former patent and trademark examiners. 

NPA International, Inc. was opened in 1995 to provide a more direct and convenient channel of communication for our North American clients. Our professionals are well-trained and equipped with substantial experience in intellectual property practice in both China and the United States. Since its establishment, NPA has been expanding its business surprisingly rapidly, as it has unparalleled advantages over other, local agencies of its kind. 

With offices located in the Washington, D.C., metropolitan area, we are able to provide clients quality services with more prompt attendance and convenient communication.
