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• extracts.7z is an archived version of the extracts/ directory for backup and transfer reasons.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

Attributes

See E:\McNair\Projects\SimplerPatentData\src\main\java\org\bakerinstitute\mcnair\models\GrantedPatent.java. In the first couple of lines there is a public enum Fields which describes what attributes are parsed out. In addition, there are 5 lists of citations, scirefs, inventors, assignees, and lawyers associated with this patent--each of which has its own parsed attributes which you can find by looking in the same directory. These attributes (except for the number of claims) are stored as strings (text) rather than numbers.
