Harvard Dataverse

Return to Patent Data (Wiki Page).
The Harvard Dataverse provides clean versions of the U.S. utility patent datasets spanning 1975-2010. The data is post author disambiguation.
For details, see the paper at Harvard Dataverse.
This page records how to load and use the Harvard Dataverse. The patents from 1975-2010 loaded as .sqlite3 and csv files can be found at Harvard Dataverse. All of the files have been downloaded to the database serverr and can be found at cd/bulk/patent.

Getting the data
Where we get the Harvard Dataverse data: Harvard Dataverse
For more information about the patent data: Patent Data (Wiki Page)
To recreate the tables:
1. run createtables.sql
2. run copytables.sql
3. run cleaning db.sql
These scripts are available under /bulk/Software/Database\ Scripts
Loading the tables into the database
COPY classes FROM '/tmp/class.csv' DELIMITER ',' NULL CSV; COPY assignees FROM '/tmp/assignee.csv' DELIMITER ',' NULL CSV; COPY citations FROM '/tmp/citation.csv' DELIMITER ',' NULL CSV; COPY inventors FROM '/tmp/inventor.csv' DELIMITER ',' NULL CSV; COPY patents FROM '/tmp/patent.csv' DELIMITER ',' NULL CSV; COPY patdescs FROM '/tmp/patdesc.csv' DELIMITER ',' NULL CSV; COPY lawyers FROM '/tmp/lawyer.csv' DELIMITER ',' NULL CSV; COPY scirefs FROM '/tmp/sciref.csv' DELIMITER ',' NULL CSV; COPY usreldocs FROM '/tmp/usreldoc.csv' DELIMITER ',' NULL CSV; COPY invpats FROM '/tmp/invpat.csv' DELIMITER ',' NULL CSV;
Accessing the dbase
On the database server, the entire Harvard Dataverse for Patent Data is downloaded in directory
/bulk/patent
The files have been processed to be used for the create table scripts I have created to load the Harvard Dataverse database into our own psql database.
These preprocessed files are available under
/bulk/patent/preprocessed
The database I have created for the Patent Data from 1975-2010 is called patent data. After logging in to researcher@128.42.44.181, you can get access to the database by
psql patentdata
You can see a list of the tables inside the patent database by
patentdata=# \dt
List of relations
Schema | Name | Type | Owner
--------+-----------+-------+------------
public | assignees | table | researcher
public | citations | table | researcher
public | classes | table | researcher
public | inventors | table | researcher
public | invpat | table | researcher
public | lawyers | table | researcher
public | patdesc | table | researcher
public | patents | table | researcher
public | scirefs | table | researcher
public | usreldocs | table | researcher
(10 rows)
You can select from the database, for example, by
patentdata=# SELECT * FROM CLASSES WHERE patent='03930270'; patent | prim | class | subclass ----------+------+-------+---------- 03930270 | 1 | 360 | 130.24 03930270 | 0 | 360 | 84 03930270 | 0 | 360 | 271.8 03930270 | 0 | G9B | 15.08 (4 rows)
Or, do a join:
patentdata=# SELECT * FROM inventors AS i, classes AS c WHERE i.Patent=c.Patent AND i.Patent='03930270';
patent | firstname | lastname | street | city | state | country | zipcode | nationality | invseq | patent | prim | class | subclass ----------+-----------+----------+--------+-----------+-------+---------+---------+-------------+--------+----------+------+-------+---------- 03930270 | YOSHINORI | YAMAZOE | | OSAKA | | JP | | | 3 | 03930270 | 1 | 360 | 130.24 03930270 | YOSHINORI | YAMAZOE | | OSAKA | | JP | | | 3 | 03930270 | 0 | 360 | 84 03930270 | YOSHINORI | YAMAZOE | | OSAKA | | JP | | | 3 | 03930270 | 0 | 360 | 271.8 03930270 | YOSHINORI | YAMAZOE | | OSAKA | | JP | | | 3 | 03930270 | 0 | G9B | 15.08 03930270 | CHIHIRO | NAKAMURA | | MORIGUCHI | | JP | | | 4 | 03930270 | 1 | 360 | 130.24 03930270 | CHIHIRO | NAKAMURA | | MORIGUCHI | | JP | | | 4 | 03930270 | 0 | 360 | 84 03930270 | CHIHIRO | NAKAMURA | | MORIGUCHI | | JP | | | 4 | 03930270 | 0 | 360 | 271.8 03930270 | CHIHIRO | NAKAMURA | | MORIGUCHI | | JP | | | 4 | 03930270 | 0 | G9B | 15.08 03930270 | SATOSHI | KIKUYA | | KADOMA | | JP | | | 2 | 03930270 | 1 | 360 | 130.24 03930270 | SATOSHI | KIKUYA | | KADOMA | | JP | | | 2 | 03930270 | 0 | 360 | 84 03930270 | SATOSHI | KIKUYA | | KADOMA | | JP | | | 2 | 03930270 | 0 | 360 | 271.8 03930270 | SATOSHI | KIKUYA | | KADOMA | | JP | | | 2 | 03930270 | 0 | G9B | 15.08 03930270 | SHIZUHIKO | TANIGAWA | | MORIGUCHI | | JP | | | 1 | 03930270 | 1 | 360 | 130.24 03930270 | SHIZUHIKO | TANIGAWA | | MORIGUCHI | | JP | | | 1 | 03930270 | 0 | 360 | 84 03930270 | SHIZUHIKO | TANIGAWA | | MORIGUCHI | | JP | | | 1 | 03930270 | 0 | 360 | 271.8 03930270 | SHIZUHIKO | TANIGAWA | | MORIGUCHI | | JP | | | 1 | 03930270 | 0 | G9B | 15.08 (16 rows)
The schema I used for this database is documented at the bottom of this page.
And this is also saved as a .sql script under
/bulk/Software/Database\ Scripts/createtables.sql
A corresponding Drop table scripts is also available at
/bulk/Software/Database\ Scripts/droptables.sql
Converting DataTypes
Method 1: Explicit recast
CAST function
Method 2: implicit recast
SELECT varname::type
Method 3: through a language
CREATE OR REPLACE FUNCTION chartoint (text) RETURNS int AS $$

The scripts for cleaning up the tables are available under /Database\ Scripts/cleaning\ db.sql
