Table Variables

The orgname (organization name) and the first and last name columns identify the patent assignee. Other than patentcountry, all other table variables apply to the organization or person. Patentcountry refers to where the patent was granted. Orgname is not standardized. Certain patents have multiple assignees, resulting in repeated patent numbers. The key in this table is composite and consists of a unique combination of last and first name, orgname, and patent number.

Current Problems

'Country' is missing.

allpatent_clone=# SELECT COUNT(*) FROM assigneeinfo WHERE country = ;

count  

---

2361543

(1 row)

allpatent_clone=# SELECT COUNT(*) FROM assigneeinfo WHERE country='unknown';
count 
-------
 3918
(1 row)

allpatent_clone=# SELECT COUNT(*) FROM assigneeinfo WHERE country IN ('unknown',' ') AND state=' ';
 count  
---------
1851353
(1 row)

UPDATE: The source of the problem seems to be the Harvard Dataverse.

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)
