This project describes the build out and basic use of the USPTO Assignment Dataset.

The data, scripts, etc. are in:

E:\McNair\Projects\USPTO Patent Assignment Dataset

The data is described in a USPTO Economic Working Paper by Marco, Myers, Graham and others: https://www.uspto.gov/sites/default/files/documents/USPTO_Patents_Assignment_Dataset_WP.pdf

Pre-load checks

The data is large. We don't have space on the main dbase server for it.

df -h
/dev/nvme1n1p2  235G  208G   15G  94% /var/postgresql

Note: To check dbase space usage on the dbase server see Posgres_Server_Configuration#Size.2C_Backup_.26_Restore.

The postgres dbase on the RDP, however, currently has more than 300Gb free and is on a solid state drive, so its performance should be acceptable.

Getting the data

The data is available pre-processed (see the working paper) from https://bulkdata.uspto.gov/#addt. Specifically, download csv.zip (1284462233, 2017-03-28 15:47) from https://bulkdata.uspto.gov/data/patent/assignment/economics/2016/

The load script is:

LoadUSPTOPAD.sql

To get the data into ASCII or ASCII, move it to the dbase server then:

  • Check its encoding using:
file -i Car.java
  • Convert it to UTF-8 using (the TRANSLIT option approximates characters that can't be directly encoded)
iconv -f oldformat -t UTF-8//TRANSLIT file -o outfile
    • The sc options forces iconv to ignore bad chars and move on:
iconv -sc -f oldformat -t UTF-8//TRANSLIT file -o outfile
  • Bash scripts to do all of the csvs is in Z:\USPTO_assigneesdata; make them executable and then run whichever you need
chmod  +x  encoding.sh
./encoding.sh
  • Note that the final source encoding was Win1252 and the final target encoding was ASCII
  • All bar three of the files had to be manually fixed to remove errors. Final files are in E:\McNair\Projects\USPTO Patent Assignment Dataset
