Subsumes: Redesigning Patent Database, Patent Assignment Data Restructure
Copyright © 2016 edegan.com. All Rights Reserved.


A continuation of Redesigning Patent Database that aims to write faster, more centralized code to deal with data from the United States Patent and Trademark Office (USPTO). By having an end-to-end pipeline we can easily reproduce or update data without worrying about unintentional side effects or missing data. Currently, it succeeds in bulk downloading from the USPTO; streaming file splitting, that is, splitting large concatenated files into their component parts in-memory; and parsing of XML to Java objects, APS to Java Maps, and maintenance fee data to Java objects.

Progress

  1. Downloader done
  2. Splitter done
  3. Parser done
  4. Create tooling for minions
  5. Setup PostgreSQL JDBC
  6. Create naive schema based on previous approaches
  7. Create new data structures
  8. Database Insert (modify models/ files with some mapping to database fields)
  9. Data Cleanup (reference Marcela and Sonia's work)
  10. Setup pipeline script to complete all of these steps in series
  11. Data Source Merger (only USPTO granted, maintfee, assignment not USPTO applications or Harvard Dataverse or Lex Machina currently)

Directory Layout

All of the information for this project is located at E:\McNair\Projects\SimplerPatentData

There are four interesting directories:

  • data/downloads/ is USPTO bulkdata, unmodified straight from the scraper
  • data/extracts/ is a directory of a strict subset of the information stored in data/downloads/. It is the result of running a bulk 7-zip job on that directory to get everything unzipped in a flat data structure. Note that these files have the USPTO modified-by time since that metadata is stored in the zipfiles. To extract files in this nice format, select all of the zipfiles and setup an extraction job like in this screenshot
  • data/backups/ is a 7zip'd backup of the corresponding directory in extracts
  • src/ is the main code repository for the java project

Input Files

All of the text-only Red Book files for granted patents from 1976 to 2016, inclusive. To find a specific year's XML file, find it in

E:\McNair\Projects\SimplerPatentData\data\extracts\granted\

To find assignment data, look in

E:\McNair\Projects\SimplerPatentData\data\extracts\granted\

To find maintenance fee data, look in

E:\McNair\Projects\SimplerPatentData\data\downloads\maintenance
