Technology Emphasis
As Determined By USPTO Patent Class

- Explanation of Data -

Listing of Technology Classes Receiving 1 or More Utility Patents During the 1999 to 2013 Period
Originating From

EUROPE, SELECTED REGIONS

(includes AT, BE, BG, CS, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR,
HR, HU, IE, IT, LT, LU, LV, MT, NL, PL, PT, RO, SE, SI, SK)

( 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 class in which 200 or more patents were granted in 2013 is identified with a 'Y' in the 'Active Class' column )
( a higher activity index indicates a higher technology emphasis; table is sorted by descending 2013 Activity Index )

This table includes counts and activity indexes that display technology emphasis by technology class and calendar year. Counts are for utility patents originating from the selected region.
