Listing of Technology Classes Receiving One or More Utility Patents During the 1998 to 2012 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 2012 Activity Index )
( activity indexes and counts of patent grants apply to the calendar year(s) in which the patents were granted )
 
( Active classes have a 'Y' in the 'Active Class' column and consist of technology classes containing 200 or more total patents granted in 2012)

The following table displays patent counts and activity indexes by technology class and calendar year for utility patents granted to U.S. colleges and universities.
