Re: Availability time-series patents and citations

Sorry to hear that a colleague of mine has given you the wrong answer. PATSTAT can answer your questions. Actually, it has been designed for exactly these types of information needs. Please note that PATSTAT is not a database which contains ready-made statistics, but provides the data structured in ...

Re: Make a Patstat query based on publication numbers

A simple way to do this is to concatenate the PUBLN_AUTH and the PUBLN_NR before doing the comparison. In T-SQL (MS SQL Server) this would look like this: select* from tls211_pat_publn where publn_auth + publn_nr = 'WO2014198277' Please note that you will not find publication US2016138562 in the cur...

Re: when will PATSTAT Online Spring 2016 edition be online?

It is foreseen that we in the PATSTAT team receive a first version of PATSTAT Online which contains the 2016 Spring data next week for test. Usually 2-3 test cycles need to be done, so I aim at making this version available for the users end of June. You mentioned that you need to compare your analy...

Re: Same PATSAT version & query, different values?

Hi Alfonso, I suppose you are using PATSTAT Online, so we are all working on the same data. I tried to reproduce your example of Y02E 10/1 Geothermal energy, because there you gave specific numbers: I used this query for the 2015 Autumn Edition: SELECT DISTINCT t.earliest_filing_year, t.nb_citing_do...

Re: Connections in Logical model diagram

Thank you for pointing this out. I will clarify that in the Data Catalog accordingly. Table REG108_APPLICANT_STATES contains additional information about applicants only, not about inventors or representatives. So it can only be sensibly joined with the applicants in table REG107_PARTIES. Applicants...

Re: Help with CPC

I copied your query and just made sure that there are 2 spaces between the CPC subclass part 'B60L' and the CPC subgroup part '11/1881'. Then the query returned 24 991 rows in the PATSTAT 2015 Autumn Edition. select tls201_appln.appln_id, appln_auth, appln_nr, appln_kind, appln_filing_date, granted,...

Re: PATSTAT Subscription Question

Your colleague is right. For example see some publications with granting effect (publn_first_grant = 1) from Switzerland: select top 10 * from tls211_pat_publn where publn_first_grant = 1 and publn_auth = 'CH' -- just as an example The publication date of publications with granting effect correspond...

Re: Inventor sequence number pre-2005

In case of multiple inventors, the inventors are printed on the publication in some order. Whether this order carries any business significance, is up to the publishing office. Nevertheless, PATSTAT retains this order information by assigning sequence numbers to these inventors (cf. tables TLS207_PE...

Re: Question about search for IPC_class_symbol

IPC as well as CPC symbols in PATSTAT are formatted according to WIPO standard ST.8. In ST.8 the main group always has 4 characters, consisting of a right aligned number and leading blanks to fill up the 4 positions. So when searching for IPC symbol B60L7/10 you must add 3 spaces, because the main g...
