Fields of Technology - By Office
Patent applications are classified according to the International Patent Classification (IPC) [link to description on this site], which can be aggregated into 30 fields, the most active technology fields being electricity and electronics.
The highest rates of activity in these fields are in the patent offices of the US and Japan.
As a PCT [link to PTC description elsewhere on this site] international application can be counted in more than one technical field, the total of applications by technical field differs from the total of applications filed.
The following WIPO charts show distribution of patent applications filed for a selection of technical fields by patent office between 2000 and 2004.
-
The patent offices of Japan and the United States of America have high rates of activity in these selected fields.
-
The distribution of patent filings in Chemical Engineering is noticeably different from the other technical fields.
The Institute of Patent and Trade Mark Attorneys of Australia (IPTA) is the peak professional body representing Australian patent and trade mark attorneys.
