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.
Contents
Quickstart
To get up and running with the code, do the following:
- Clone the git project (link at end of page) to your user directory
- Launch IntelliJ with >= Java 8 and Maven configured (default version installed on the RDP is setup to do this)
- Open project in IntelliJ
- Create an empty database (see #Database)
- Run the table creation scripts in
src/db/schemas/
in your new database - Modify the constant
DATABASE_NAME
inE:\McNair\Projects\SimplerPatentData\src\main\java\org\bakerinstitute\mcnair\postgres\DatabaseHelper.java
- Run the Driver scripts in IntelliJ with the correct value for
DATA_DIRECTORY
- [Take a really, really long lunch...in total should take no more than five hours to load data on RDP]
- Run scripts in
src/db/constraints
to check data assumptions - That's it!
Directory Layout
Where is the Data?
Directories
All of the information for this project is located at E:\McNair\Projects\SimplerPatentData
There are several interesting directories:
data/downloads/
is USPTO bulkdata, unmodified straight from the scraperdata/extracts/
is a directory of a strict subset of the information stored indata/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 screenshotdata/backups/
is a 7zip'd backup of the corresponding directory in extractssrc/
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 application data from 2001 to 2016, inclusive, look in
E:\McNair\Projects\SimplerPatentData\data\extracts\applications\
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\
Where is the Code?
The code has the same parent directory as the data, so it is at E:\McNair\Projects\SimplerPatentData\src
. You might notice a lot of single-entry directories; this is an idiomatic Java pattern that is used for package separation. If using IntelliJ or some other IDE, these directories are a bit less annoying.
The development environment is Java 8 JDK, IntelliJ Ultimate IDE, Maven build tools, and git VCS.
The git repository can be found at https://rdp.mcnaircenter.org/codebase/Repository/ReproduciblePatent
Prior Art
This tool is not so concerned with adding new functionality; rather, it aims to take a bunch of spread out Perl scripts and create a faster system that is easier to work with. As such, its functionality is largely stolen from those scripts:
- Downloader:
E:\McNair\Software\Scripts\Patent\USPTO_Parser.pl
- XML Splitter:
E:\McNair\PatentData\splitter.pl
- XML Parsing:
E:\McNair\PatentData\Processed\xmlparser_4.5_4.4_4.3.pl
andE:\McNair\PatentData\Processed\*.pm
In addition, I used several non-standard Java libraries listed below:
- Unirest for easy HTTP requests (MIT License)
- Google Guava for immutable collections and Stream utilities (Apache v2.0 License)
- jsoup for HTML parsing (MIT License)
- Apache Commons Codec (Apache v2.0 License)
- Apache Commons Lang v3 (Apache v2.0 License)
- Jetbrains Annotations for enhanced null checks (Apache v2.0 License)
- PostgreSQL JDBC (BSD 3-clause per https://github.com/pgjdbc/pgjdbc-jre7/blob/master/LICENSE)
If using maven, these dependencies are listed and should automatically be setup.
Using Code
Any file with a line that says public static void main(String[] args) {
can be run as a standalone file. The easiest way to do this is to load the project and then the file in IntelliJ and click the little green play arrow next to this bit of code.
The code can also be run via the standard javac
and java
commands but since this project has a complicated structure you end up having to run commands like
"C:\Program Files\Java\jdk1.8.0_131\bin\java" "-javaagent:C:\Users\OliverC\IntelliJ IDEA 2017.1.3\lib\idea_rt.jar=62364:C:\Users\OliverC\IntelliJ IDEA 2017.1.3\bin" -Dfile.encoding=UTF-8 -classpath "[...contents truncated...];C:\Users\OliverC\.m2\repository\org\postgresql\postgresql\42.1.1\postgresql-42.1.1.jar" org.bakerinstitute.mcnair.uspto_assignments.XmlDriver
to include all of the runtime dependencies and it's just not worth it.
Altering Code
- Use the IntelliJ command Reformat code (found in the menus at
Code > Reformat Code
- Use the optimize imports function found under the same menu
- Use spaces for indentation
- Loosely try to keep lines below 120 characters
- Commit changes to the Git remote repository "bonobo"

APS Rosetta Stone
The Advanced Patent System (APS) is a fixed-width text format used to store historical patent grant data. The documentation for this sucks; there are pages missing at random. Luckily, we only care about the content contained here: File:PatentFullTextAPSDoc GreenBook pgs13-22.pdf.
It's worth mentioning that the APS contains an advanced text markup system for chemical formulae, basic text markup, tables, etc. that can lead to seemingly garbled text that is perfectly well-formed.
APS Gotchas
- PATN.WKU is the granted patent number. It is 7 digits while the spec promises 6 digits. The rightmost digit is a check digit modulus 11. See File:Aps-wku-modulus11.pdf for the words from the horse's mouth.

Database
Because there isn't a compelling reason not to, I used the existing PostgreSQL infrastructure on the RDP. The "Java Way" of interacting with databases is the Java Database Connectivity API (JDBC), an implementation-agnostic API for interacting with databases. This project uses the stock Postgres JDBC, version 42.1.1
Create an empty database on RDP
To create an empty database, run this command: $ createdb --username=postgres database-name-goes-here # password is tabspaceenter
Abstraction Layer
Since writing raw SQL is a bit cumbersome and error-prone, I have added some abstraction layers that make it much easier to quickly add bulk data. By using Postgres's CopyManager
class, we buffer SQL copy commands in memory (as many as possible) and then flush these rows. To understand how the abstraction layers work, see the code in E:\McNair\Projects\SimplerPatentData\src\main\java\org\bakerinstitute\mcnair\postgres
. See E:\McNair\Projects\SimplerPatentData\src\main\java\org\bakerinstitute\mcnair\models\GrantedPatent.java
for an example of how to extend the abstraction layer to deal with more complex scenarios.
