Downloading the files

The files (in xml format) for granted patent data can be obtained at granted patent

The files for patent application data can be obtained at patent applications

The files for maintenance fees data can be obtained at maintenance

Scripts are available to perform a bulk download of all the above files

These scripts can also be found under /bulk/Software/download\ scripts ("E:\Software\download scripts")on McNair RDP:

Script to download patent application data from 2001-2004

Script to download patent application data from 2005-2015

Script to download patent grant data from 1976-2000

Script to download patent grant data from 2001-2004

Script to download patent grant data from 2005-2015

To use the scripts, save the scripts as shell scripts, then either 

$ sh Applications_download_2001-2004.sh

or first change the script to an executable and execute it 

$ chmod a+x Applications_download_2001-2004.sh
$ ./Applications_download_2001-2004.sh

Notice there will be several hundreds of .zip files of size ~100mb getting downloaded so the process might take a while. When all the files are downloaded, unzip all of them using 

$ unzip *.zip

XML Schema Notes

Parsing and Processing the XML files

The ParserSpliter.pl script will first split a large Patent Data XML file into smaller XML files, one for each patent data. And it will then parse and process each Patent Data XML file.

Some of the files are somehow mal-formatted, and will be moved to a ./failed_files directory If you add a character anywhere in these files, they somehow become fine to be processed by the script.

In order to use this script, you will need to have XML::Simple and Try::Tiny installed.

Open up CPAN shell: 

$ perl -e shell -MCPAN

Install: 

cpan[0]> install XML::Simple
cpan[1]> install Try::Tiny
cpan[2]> install Switch

Once the packages have been installed, use the script like the following example: 

perl PatentParser.pl -file=ipa150319_small.xml

New Notes

The source files have transitioned from here:

To:

The historic data is the same both sides.

Each file contains, in order, sorted by document ID:

  1. Design patents (we will discard)
  2. Plant patents (we will discard)
  3. Reissues (we probably want them)
  4. Utility patents (we want them)

The classifications in the XML file are:

  • IPC - these are good and we just need the main classification
  • CPC - as above
  • USPC - just a numeric but not split. Is 22431 224/31 or 22/431, etc.

Scripts

All the scripts related to the patent Data are at: 

\\father\bulk\Software\Scripts\Patent

USPTO_Parser.pl will parse the USPTO website and downloads the concatenated xmls to: 

\\father\bulk\PatentData

It should be run as follows 

USPTO_Parser.pl year1 year2

Gets the data from year1 to year2

Splitter.pl will split those concatenated xmls into individual xmls into: 

\\father\bulk\PatentData\Processed

Fields of Interest

We only care about Utility patents (and maybe Reissue patents too)

Utility patent grants fields

For version 4.5:

For priority, if there is more than 1, we want sequence 01

  • prioritydate
  • prioritycountry (should use ISO country codes - may need a lookup table)
  • prioritypatentnumber
  • find 4.3 file with priority claim
<priority-claims>
 <priority-claim sequence="01" kind="national">
  <country>GB</country>
  <doc-number>1016384.8</doc-number>

Classification IPC - we only need the first one: http://www.wipo.int/export/sites/www/classifications/ipc/en/guide/guide_ipc.pdf

Classification CPC - we only need the main one

CPC is a classification scheme set up by the USPTO and the European Patent Office (EPO). The first classification codes rolled out on November 9, 2012.[2] Full implementation of the CPC classification system occurred on January 2015, at the same time of version 4.5 of the USPTO patent bulk data.[3]

  • Section, Class, Subclass
  • Main Group, Subgroup
  • v 4.2, 4.3, 4.4 does not have this
<classifications-cpc>
 <main-cpc>
  <classification-cpc>
    <cpc-version-indicator>
      <date>20130101</date>
    </cpc-version-indicator>

    <classification-value>I</classification-value>
 ... 
   </classification-cpc>
  </main-cpc>
</classifications-cpc>

Classification National: Note that the one below comes out to 2/2.11 (http://www.google.com/patents/US8925112#classifications)

  • Country
  • Class

THIS IS NOT UNIQUE. What classifications are we searching for? 

<classification-national>
 <country>US</country>
  <main-classification>2 211</main-classification>
</classification-national>

Title of the patent: 

<invention-title id="d2e61">Aircrew ensembles</invention-title>

Number of Claims: 

<number-of-claims>12</number-of-claims>

Primary examiner:

PCT/Regional Patent Number:

  • PCTNumber (just the doc number - if it starts with PCT set a flag)
  • not in all v 4.5
  • not in v 4.2, 4.3, 4.4
  • maybe not all patents are filed under PCT, need to use code to search all files for key word

Other things we might want

  • Abstract
  • Claims (other than their count)

Things we don't need

General:

Classification related:

  • Level - This appears to be either core or advanced. Not sure it matters.
  • SymbolPosition, ClassificationValue - we likely don't need them
  • Classification status and data source - no idea what these do

About the scripts

The scripts to process the Patent Data are all located under /bulk/Software/Scripts/PatentData/ ("E:\Software\Scripts\PatentData\")

There are currently 5 .pm files: PatentApplication.pm, Inventor.pm, Claim.pm, and Addressbook.pm, and Loader.pm available.

Each of the first 4 represents an Object type. The last one is a helper object that is able to extract the wanted fields as a perl object given a schema file. Future work should be done in this file to support more schema files.

Example Usage: 

perl PatentParser.pl -file=ipa150319.xml

This will parse the xml file with name ipa150319.xml, extract all the Patents (in this case PatentApplications) each as a temporary xml file, and then, using a Loader object with a specified schema file, in this case "us-patent-application-v44-2014-04-03.dtd" to be able to extract each of the 4 object types from the Patents. If any error happened during the parsing of any file, that file will be moved to a directory called "failed_files". Most likely if a file failed the parsing it is likely not a Utility patent.

About the Harvard Dataverse

The patents from 1975-2010 loaded as .sqlite3 and csv files can be found at

Harvard Dataverse

I have also downloaded all of them on to the database server and can be found by 

cd /bulk/patent
