I am new to SQL and PATSTAT and trying to conduct a query for my thesis. Hopefully I am getting support here.
What do I want to query?
I want to do a query where I get: "All patent applications of a company X where there are more than 1 applicants (companies) in a specific time span"
For example: I want an answer to the question: How many patents did a company X apply together with other companies from 2005 to 2011".
Am I right with the statement, that one invention can be patented in several countries? If this is true, I just want to measure new inventions.
Regarding that, I found that it is not that easy searching for a specific company, because for example Samsung has a lot of subsidiaries which are applicating patents. Drawing on another post in this forum, I would maybe try to do the following query which is giving the organizations with most patent applications with the word for e.g. Samsung in it:
Then I would pick the top 5 results for each company and try to answer the question mentioned above.
Code: Select all
select tls208_doc_std_nms.doc_std_name_id, tls208_doc_std_nms.doc_std_name, COUNT(*) FROM tls201_appln INNER JOIN tls207_pers_appln ON tls201_appln.appln_id=tls207_pers_appln.appln_id INNER JOIN tls206_person ON tls207_pers_appln.person_id=tls206_person.person_id INNER JOIN tls208_doc_std_nms ON tls206_person.doc_std_name_id=tls208_doc_std_nms.doc_std_name_id WHERE tls208_doc_std_nms.doc_std_name LIKE '%Samsung%' GROUP BY tls208_doc_std_nms.doc_std_name_id ORDER BY COUNT(*) DESC;
If you have any other suggestions on how to do this query - feel free to answer. Meanwhile I am trying to get an solution myself.
Really looking forward to an answer.
