Technology Emphasis
As Determined By USPTO Patent Class
1995 and 2005

- Explanation of Data -

Listing of Technology Classes Receiving One or More Utility Patents During the 1991 to 2005 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 2005 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 2005)

The following table displays patent counts and activity indexes by technology class and calendar year for the U.S. Colleges and Universities-
