Information Sources in Patents (Hardcover, 4th completely rev. ed.)

This completely revised and expanded edition recognises the growing importance of patent systems and documentation from Asia, South America and Africa. The most prominent patent systems from these regions are treated individually, together with revisions to existing country coverage and an overview of IP developments in general. This is an essential reference tool for librarians, information specialists, data analysts and others seeking to use patent information either at the document level or in bulk.
