Secondary Sources of Patent Information

This expression relates to all kinds of sources, except patent documents (e.g., journals, official gazettes, databases, etc.), which supply bibliographic data on patent documents and information on their contents in a convenient and consolidated form, e.g., by an abstract or by a reproduction of the main claim(s), plus a reproduction of the basic drawing(s) or formula(e) whenever appropriate. Secondary sources of patent information imply, but are not restricted to, official gazettes, abstract pamphlets or indexes published by intellectual property offices. Often, secondary sources of patent information originate from specialized commercial institutions.
