Canadian Patent Office

Second to the United States Patent Office, the largest database is accessed through the European Patent Office, where one should conduct a similar classification search as suggested previously for the United States Patent and Trademark Office (2). The World Intellectual Property Organization (3) offers many useful features including complete details of the Patent Cooperative Treaty and its gazette. The Canadian Patent Office can be reached at the website mentioned in Ref. 4.
