====Possible Solution====
Jul 8, 2016: The blank citedpatentnumbers were created due to inconsistency between the original type and the type in the citation table (string to integer). The blank entries mostly correspond to publication number, non-U.S. patent number, and non-standardized patent number. The next step would be to recreate the table accounting for these issues. The U.S. publication number could be matched to the publications numbers in the histpatent table and be replaced by the corresponding patent numbers.
The foreign cited patents will be moved to a separate table.
===Assignees Table===
'Country' is missing.
allpatent_clone=# SELECT COUNT(*) FROM assignees WHERE country=' ';
count
---------
2361543
(1 row)
allpatent_clone=# SELECT COUNT(*) FROM assignees WHERE country='unknown';
count
-------
3918
(1 row)
allpatent_clone=# SELECT COUNT(*) FROM assignees WHERE country IN ('unknown',' ') AND state=' ';
count
---------
1851353
(1 row)
UPDATE: The source of the problem seems to be the Harvard Dataverse.
===Assignees & assigneesUSU Tables===
No information provided about the assignee. No entries for orgname or first and last names.
allpatent_clone=# SELECT COUNT(patentnumber) FROM assignees WHERE (orgname='' OR orgname IS NULL) AND (firstname='' OR firstname IS NULL) AND (lastname='' OR lastname IS NULL);
count
--------
344794
(1 row)
AssigneesUSU table was made with the following code:
SELECT orgname, patentnumber, country, firstname, lastname, state
INTO assigneesUSU -- assignees in US,unknown, and blank entries
FROM assignees
WHERE country IN ('US', '', 'unknown') OR (state IS NOT NULL AND state!='')
ORDER BY orgname;
allpatent_clone=# SELECT COUNT(patentnumber) FROM assigneesUSU WHERE (orgname='' OR orgname IS NULL) AND (firstname='' OR firstname IS NULL) AND (lastname='' OR lastname IS NULL);
count
--------
344793
(1 row)
The table has two columns, 'citingpatentnumber' and 'citedpatentnumber'. There are rows with 'citedpatentnumber' greater than 10000000. For instance:
