|---|---|
| Description: | Converts TXT and XML data curated by the United States Patent and Trademark Office (USPTO). Allows conversion of bulk data after downloading directly from the USPTO bulk data website, eliminating need for users to wrangle multiple data formats to get large patent databases in tidy, rectangular format. Data details can be found on the USPTO website <https://bulkdata.uspto.gov/>. Currently, all 3 formats: 1. TXT data (1976-2001); 2. XML format 1 data (2002-2004); and 3. XML format 2 data (2005-current) can be converted to rectangular, CSV format. Relevant literature that uses data from USPTO includes Wada (2020) <doi:10.1007/s11192-020-03674-4> and Plaza & Albert (2008) <doi:10.1007/s11192-007-1763-3>. |

Download and convert bulk patent data to tidy format from the USPTO website <https://bulkdata.uspto.gov>. Data can be returned as a data frame or written to a file (see 'output_file' parameter). Since USPTO issues patents weekly, at minimum, all patents from a given week must be acquired at once.
get_bulk_patent_data(year, week, output_file)get_bulk_patent_data(year, week, output_file)
year |
integer vector containing years from which patents should be collected |
week |
integer vector of weeks within the corresponding 'year' element from which patents should be collected |
output_file |
variable of class 'character'; will output to that file in CSV format |
either 'TRUE' (placeholder) or object of class 'data.frame' (see param 'output_file' for details)

Convert WKU identifier provided in bulk patent files to patent number used in most sources. The References provided in bulk patent files are also in patent number format, not in WKU format.

A dataset containing information about patents issued by the United States Patent and Trademark Office (USPTO) <https://www.uspto.gov/> in the first week of the year 1976. This can be recreated by running the 'get_bulk_patent_data' function in the 'patentr' package and setting the 'year' and 'week' parameters to '1976' and '1', respectively.
