| Title: | Access USPTO Bulk Data in Tidy Rectangular Format |
| Version: | 0.1.4 |
| 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>. |

Get Bulk Patent Data from USPTO
Description
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.
Usage
get_bulk_patent_data(year, week, output_file)
Arguments
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 |
Value
either 'TRUE' (placeholder) or object of class 'data.frame' (see param 'output_file' for details)
Examples
## NOTE: none of the examples are run due to the download requirement
## Not run:
# download patents from the first week of 1976 and get data frame
patent_data <- get_bulk_patent_data(year = 1976, week = 1)
# download patents from the last 5 weeks of 1980 (and write to a file)
get_bulk_patent_data(year = rep(1980, 5), week = 48:52,
output_file = "patent-data.csv")
## End(Not run)
Get Patient Number from WKU
Description
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.
Usage
wku_to_pno(wku)
Arguments
wku |
character vector containing patent WKUs |
Value
character vector containing patent numbers
Examples
# convert sample WKUs to patent number and print
sample_wku <- c("RE028671", "03930271")
print(wku_to_pno(sample_wku))
Patents issued in week 1 of the year 1976.
Description
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.
Usage
y1976w1
Format
A data frame with 1379 rows and 9 variables:
- WKU
unique patient identifier
- Title
patent title
- App_Date
date on which patent application was submitted
- Issue_Date

- Inventor
patent inventor(s)
- Assignee
person(s)/corporation(s) to whom the patent was assigned
- ICL_Class
patent classification based on IPC system
- References
