[Taken verbatim from the above url]

These data comprise detail information on almost 3 million U.S. patents granted between January 1963 and December 1999, all citations made to these patents between 1975 and 1999 (over 16 million), and a reasonably broad match of patents to Compustat (the data set of all firms traded in the U.S. stock market).

These data are described in detail in

href="http://papers.nber.org/papers/w8498.pdf">Hall, B. H., A. B. Jaffe, and M. Tratjenberg (2001). "The NBER Patent Citation Data File: Lessons, Insights and Methodological Tools." NBER Working Paper 8498.

ALL USERS OF THESE DATA SHOULD READ THIS PAPER, AND SHOULD CITE IT AS THE SOURCE OF THE DATA

...

The data are freely available below in two compressed (".zip") formats: SAS transport (.tpt) files and ASCII comma-separated variable (.csv) files. The program read_tpt.sas can be used to convert the .tpt files to native SAS data sets. Lines in the ASCII CSV files are terminated by the newline character "n". "CSV" stands for comma separated values. All values in the ASCII CSV files are separated by commas. In addition, the character values are enclosed by double quotes. The compression ratio for the compressed files is about 75%. The ".zip" files can be uncompressed with winzip or pkunzip. To check your ability to uncompress these files, download the small file compress.zip. The SAS ".tpt" files are transferable to other formats using software such as Stat/Transfer or DBMS/Copy
