Re: Errors setting foreign keys in Postgresql

Regarding your point 1: Yes, there is a slight inconsistency, due to some earlier data cleaning. But I only see a single inconsistency, not 2 occurrences; You can resolve this issue by removing the record with PERSON_ID = 52249751 from table TLS226_PERSON_ORIG. The next PATSTAT version will correct ...

Re: Count of Utility Model Applications

Hell lionpat, your question is rather an SQL- syntax problem then a PATSTAT question. Here is a query that gives you the top 20 UM filers in Germany per year, based on their total number of UM applications. SELECT top 20 psn_name, COUNT(distinct(case when year(appln_filing_date) = 2000 then tls201_a...

Re: Family Cleaned Forwrad Patent Citations

Hello Vanessa, To make it easy, I only look at citations of publications; citations to applications are rather minimal in comparison. The basics: Your forward citations are in principle the same as a backward citation, if A cites B then B is cited by A. Logics define that B cannot be cited by A, unl...

Re: Help with SQL query_caunt applications per Country

Your query is perfectly fine. I ran it on PATSTAT Online and it took just 7 seconds to retrieve all 48 901 rows. In case you used PATSTAT Online, please try it again. Probably the system had some hick-up. Note that PATSTAT Online kills all queries automatically if they take more than 1 hour. So wait...

Re: IPC classes and the technology field description

The data from table TLS901_TECHN_FIELD_IPC is taken from an Excel sheet published by WIPO, which does not contain the descriptions of the IPC symbols it contains. Descriptions and further information about IPCs are not part of PATSTAT. They can be accessed from WIPO in XML, HTML or PDF format(www.wi...

Re: Support for automation

Hello Rachie, the download platform is indeed not the most user-friendly one. The link to the download page is included in the e-mail when we announce the uploading of the new PATSTAT release. For the purpose of scripting, we offer you to make use of our REST interface. The attached PDF explains det...

Re: Forward and Backward Citation

Hello Wei, continuing on the same example; and assuming you mean "granted of the cited documents" you can simply "JOIN" a tls201_appln table to the "Cited" table (alias), and then add the attribute "GRANTED" in your SELECT clause. That will give for each citation a value "Y" or "N", depending on whe...

Re: Forward and Backward Citation

Hello Wei, the person_ctry_code is the country code used for correspondence, we also call it the "place of business". It has no link to nationality or citizenship. About the tls226 table, the residence code is only used in US data and only about 1200 inventors have a residence_ctry_code <> person_ct...

Re: Forward and Backward Citation

Hello Wei, A couple of observations: In your query, you tried to count at the same time the forward and the backward citations. If one would want to do this, the query would need to have 2 joins via tls212, one to the forward citations and one to the backward citations. I feel this is needlessly com...
