The Patent Data page is for instructions on how to get the USPTO patent data, how to use the database, and for the documentation of our database. == ER diagram ==[[Image:Patent_Data.png|1024x768px]] == Downloading the files ==The files (in xml format) for granted patent data can be obtained at #REDIRECT [https://www.google.com/googlebooks/uspto-patents-grants-text.html granted patent] The files for patent application data can be obtained at [https://www.google.com/googlebooks/uspto-patents-applications-text.html patent applications] The files for maintenance fees data can be obtained at [https://www.google.com/googlebooks/uspto-patents-maintenance-fees.html 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:  [http://www.edegan.com/wiki/index.php/Image:Applications_download_2001-2004.sh Script to download patent application data from 2001-2004] [http://www.edegan.com/wiki/index.php/Image:Applications_download_2005-2015.sh Script to download patent application data from 2005-2015] [http://www.edegan.com/wiki/index.php/Image:Grant_download_1976-2000.sh Script to download patent grant data from 1976-2000] [http://www.edegan.com/wiki/index.php/Image:Grant_download_2001-2004.sh Script to download patent grant data from 2001-2004] [http://www.edegan.com/wiki/index.php/Image:Grant_download_2005-2015.sh 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== Tags we are using:*CPC Classification: https://en.wikipedia.org/wiki/Cooperative_Patent_Classification Tags we aren't using:*Kind codes: http://www.uspto.gov/learning-and-resources/support-centers/electronic-business-center/kind-codes-included-uspto-patent*Series codes: http://www.uspto.gov/web/offices/ac/ido/oeip/taf/filingyr.htm == 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 ==Other Resources== The Harvard Dataverse page: [http://www.edegan.com/wiki/index.php/Harvard_Dataverse] [http://www.uspto.gov/learning-and-resources/xml-resources Documentations for the xml files] [http://www.uspto.gov/learning-and-resources/xml-resources/xml-resources-retrospective See Also] [https://www.w3.org/2000/04/schema_hack/ tool to convert dtd to xsd] [https://dataverse.harvard.edu/dataset.xhtml?persistentId=hdl:1902.1/15705 Harvard Dataverse] ==New Notes== The source files have transitioned from here:*https://www.google.com/googlebooks/uspto-patents-grants-text.html (No longer maintained)To:*https://bulkdata.uspto.gov/ (includes 2016 data) The historic data is the same both sides. Each file contains, in order, sorted by document ID:#Design patents (we will discard)#Plant patents (we will discard)#Reissues (we probably want them)#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\PatentUSPTO_Parser.pl will parse the USPTO website and downloads the concatenated xmls to: \\father\bulk\PatentDataIt 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 Note: The ByYear (2010-2016) folders are for convenience (the XMLs inside them are post-processed to deal with genome sequences)xmlparser_4.5_4.4_4.3.pl is the script that processes the xmls given the path where the xmls are stored. This script is located at \\father\bulk\PatentData\ProcessedIt should be run as xmlparser_4.5_4.4_4.3.pl '\\father\bulk\PatentData\Processed\2010'This will process all the xmls present in the 2010 directory and store them in the database.The database connection string is hard coded for now inside the script. The database name is patentDB (located in the postgres installation of the RDP server). We then pg_dump them and pg_restore on the dbase server. ==Fields of Interest== We only care about Utility patents (and maybe Reissue patents too) ===Utility patent grants fields=== ====Patent==== *patent number*kind: http://www.uspto.gov/patents-application-process/patent-search/authority-files/uspto-kind-codes*grantdate For version 4.5: <publication-reference> <document-id> <country>US</country> <doc-number>08925112</doc-number> <kind>B2</kind> <date>20150106</date> </document-id> </publication-reference> *type*applicationnumber*filingdate <application-reference appl-type="utility"> <document-id> <country>US</country> <doc-number>13824291</doc-number> <date>20110929</date> </document-id> </application-reference> 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> <date>20100930</date> </priority-claim> </priority-claims> Classification IPC - we only need the first one: http://www.wipo.int/export/sites/www/classifications/ipc/en/guide/guide_ipc.pdf*Section, Class, SubClass - Together these concord to US subclass: http://www.uspto.gov/web/patents/classification/international/ipc/ipc8/ipc_concordance/ipcsel.htm#a*MainGroup, SubGroup  <classifications-ipcr> <classification-ipcr> <ipc-version-indicator> <date>20060101</date> </ipc-version-indicator> <classification-level>A</classification-level> <section>B</section> <class>64</class> <subclass>G</subclass> <main-group>6</main-group> <subgroup>00</subgroup> <symbol-position>F</symbol-position> <classification-value>I</classification-value> ... </classification-ipcr> ... </classifications-ipcr> Classification CPC - we only need the main one CPC is a classification scheme set up by the USPTO and the European Patent Office (EPO).

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.xmlThis 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 specifiedschema 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  [https://dataverse.harvard.edu/dataset.xhtml?persistentId=hdl:1902.1/15705 Harvard Dataverse] I have also downloaded all of them on to the database server and can be found by cd /bulk/patent
