Technology Emphasis
As Determined By USPTO Patent Class
1994 and 2004

- Explanation of Data -

Listing of Technology Classes Receiving One or More Utility Patents During the 1990 to 2004 Period

( patent origin is determined by the residence of the first-named inventor )
( technology class is determined by the primary classification assigned to the patent- see 'Explanation of Data' )
( a higher activity index indicates a higher technology emphasis; the table is sorted by descending 2004 Activity Index )
( activity indexes and counts of patent grants apply to the calendar year(s) in which the patents were granted )
 
( An Active Class has a 'Y' in the 'Active Class' column and is a class that contains 200 or more total patent grants in 2004)

This table displays counts and technology emphasis indexes by technology class and calendar year for U.S. Government Utility Patent Grants.
