Documentation from the original NBER Patent Data Project

 

2006 edition of the NBER patent data  - GO HERE FIRST – 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.

 

2006 NBER patent data – some additional files on my website

 

2002 Updates to NBER patent data. Unless otherwise noted, data files are in stata format version 6, 7, or 9, which are readable by stata or tsp. If you wish another format, I suggest you acquire stat/transfer, an excellent program that converts data files to and from a large variety of formats.

 

·         Documentation for NBER data

·         Data on patents issued 1963-2002 in stata 7 format     (updated 4 Dec 04 to add asscode and 2002 patent assignee number)

·         List of standardized 2002 patent assignee names corresponding to pat63_02 in stata 7 format

·         Citations for patents issued 1975-2002 in stata format

1999 NBER patent data files (Hall, Jaffe, and Trajtenberg 2002 version)

USPTO Patent Database search

Full text search for patents from 1976. Patents from 1790 through 1975 are searchable only by Issue Date, Patent Number, and Current US Classification.

 

Google bulk downloads

Up-to-date bulk downloads available for a large range of USPTO data – take a look.

 

Google patent search beta

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).

 

ip.com

Free patent search that includes US patents and patent applications as well as Chinese (PRC) patents (both in Chinese and in English translation), the Prior Art publications in IP.com's own Prior Art Database, and IBM Redbooks.

esp@cenet – EPO

The European Patent Office’s search site, which includes applications and grants from the EPO, WIPO, and worldwide. Note that you should use worldwide search (not EP search) for patents with an application date older than 24 months

 

Patent family data at INNO-Tec, LMU

Data provided by Dietmar Harhoff, which allocates each application (identified via the appln_id variable) in the PATSTAT triadic patent data (version April 2007) to exactly one group of patents with the same set of Paris Convention priorities. In principle this can be used to construct a consistent set of citation data that takes account of variations across patents in the offices that they cite. There is also very useful documentation available on this website.

 

OECD Patent Data

 

Japanese Patent Office Data from IIP

The new IIP Patent database, produced under the supervision of Akira Goto and Kazuyuki Motohashi. Data on 9 million applications and 2.7 million registrations (grants) from the early 20th century to January 2004. Includes citations and owner information.
