Patenting In U.S. Metropolitan Areas (ALL METROPOLITAN AREAS), Breakout By Technology Class, CY2000-2015 Patents Distributed By Year of Grant

( patent origin is determined by the residence of the first-named inventor )
( technology class is determined by the primary classification assigned to a patent- see 'Explanation of Data' )
( some classes have been combined together under a single class identifier )
( patent counts may not sum exactly due to rounding - see the Explanation of Data )
( regional areas are based on U.S. Core Based Statistical Area (CBSA) )

*The following table displays technology classes and counts of utility patents classified in them; patents are distributed by year of patent grant.*
