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 the USPTO data. By having an end-to-end pipeline we can easily reproduce or update data without worrying about unintentional side effects or missing data.

Directory Layout

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

There are three interesting directories:

• zipfiles/ is USPTO bulkdata, unmodified and validated to have the correct file size
• extracts/ is a directory of a strict subset of the information stored in zipfiles/. 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.
• src/ is the main code repository for the java project

In addition, there are three interesting files in the base directory:

• extracts.7z is an archived version of the extracts/ directory for backup and transfer reasons.

Name: extracts.7z
Size: 55847284301 bytes (53260 MB)
SHA256: C653E5B736530711DB2212191853EAABBF36CF48820915F8B57DB54E1990BDC0

• hashes.tsv is a tab-separated value file with SHA-256 hashes of the files as downloaded from the USPTO.
• index.tsv is a tab-separated value file with the URLs, modified-by datetime, and supposed filesize in bytes.

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

TODO (in order)

1. Flesh out equivalencies for all XML schemas
2. Ditto APS
3. Ditto Maintenance Fee Data
4. Create a new DB schema using a less centralized conception of a patent
5. Check correctness versus existing data
6. Store abstracts, processing metadata
7. Investigate USPTO products for addressees
8. Handle addressee data
