The article presents an analysis of data on patent publications from the U.S. Patent & Trademark Office (USPTO), the European Patent Office (EPO) and the Japan Patent Office (JPO) between 1976 and 2006. It has been found that the USPTO had granted 7,406 nanotechnology patents during the period, which was about two times the number granted by the EPO and over six times the number granted by the JPO. The three distinct phases in the history of nanotechnology were also studied.
