NBER patent data

 

Documentation from the original NBER Patent Data Project

 

2006 edition of data  - GO HERE FIRST FOR NBER PATENT DATA – this is the most up-to-date version of the NBER data that I know about. Further inquiries should be directed to Iain Cockburn at Boston University, not to me.

Patent search and data sites:

 

Google patent search

Google Patent Search covers the entire collection of patents made available by the USPTO—from patents issued in the 1790s through those issued in the middle of 2006. “We don’t currently include patent applications, international patents, or U.S. patents issued over the last few months, but we look forward to expanding our coverage in the future.” BHH note: some patents appear to be missing (e.g., 3930271, issued Jan 6 1976, the first one in the computerized data base).
