Patent applications by field of technology,,,,,,,
"WIPO Statistics Database, 2011",,,,,,,
"Note: The International Patent Classification (IPC) symbols assigned to the patent document are linked to the fields of technology by a concordance. Because a patent application may be assigned multiple IPC symbols, the sum of patent filings by fields of technology is higher than the total number of patent filings.",,,,,,,
