Patenting Trends in the United States (1963-2008)
-------------------------------------------------
This report profiles U.S. patenting in 30 product fields (26 unique 
fields, and several fields that are combinations or roll-ups of the 
26 unique fields) that are based on the 2002 North American Industry 
Classification System (NAICS). For each product field, the report 
lists patent counts in a format similar to Parts A1 and A2 of the 
PTMT "All Technologies Report". Presented are patent activity by 
country of origin (for the most active countries) and by ownership 
category, with activity distributed by the year of patent grant and 
by the year of patent application. The report counts patents in two 
ways, using a "fractional count" method and a "whole count" method. 
For viewing patent activity, the preferred patent counting method 
will depend on the intended usage of the information.

A separate portion of the report presents patent activity in the
identified product fields by state and country of origin for all 
states and countries. Separate counts are provided using the 
"fractional count" method and the "whole count" method.
