The patentr R package allows easy access to USPTO (United States Patent and Trademark Office) bulk patent data in tidy, rectangular format. By downloading, converting, and storing patent data directly from the USPTO website, patentr minimizes the work needed to acquire usable data, allowing users to focus on analyzing the data.


To install patentr, run the following R code:

# install from CRAN

# install development version from GitHub

Sample code

Bulk patent data can be downloaded using the year and week (within each year) as follows:

# load patentr

# download patents from the first week of 1976
get_bulk_patent_data(year = 1976,
                     week = 1,
                     output_file = "patent_output1.csv")

# download patents from:
#   1. week 1 of 1976 (TXT format in USPTO)
#   2. week 48 of 2002 (XML format 1 in USPTO)
#   3. week 19 of 2006 (XML format 2 in USPTO)
# N.B. it will take a few minutes to run the next line
get_bulk_patent_data(year = c(1976, 2002, 2006),
                     week = c(1, 48, 19),
                     output_file = "patent_output2.csv")

  • patent title
  • application date
  • issue date
  • inventor name(s)
  • assignee name(s)
  • ICL classification
