Historic Patent Data

We are in the process of harvesting images of historic patents. Using Tesserac, we are developing parsing algorithms to OCR and harvest key variables useful for academic studies of innovation and entrepreneurship:

  • Identify key variables of the patent (date, ownership, title, abstract).
  • Identify the description and claims of the patent.
  • Identify the backward (and therefore forward) citations of each patent.

We have identified several different USPTO templates in our preliminary analyses, having harvested about 2 million of the 5 million necessary patents.

Updated Industry Partner (December 2014)

Due to limited university resources necessary to OCR 9+ million patents and over 90+ million patent pages, we approached an industry partner. The resulting dataset is available within CRIE to members of Mergent Patent Archives.
