Re: tls231_part01

Hi Leo,

Which version of PATSTAT data are you using? 2017 Autumn Edition?
To check whether the downloading introduced some error:
- After downloading, have you compared the SHA values?
- Or have you tried to download that particular file again?

Best regards,
Martin

Re: Retrieving patents with inventors spread across multiple countries

PATSTAT Online is a read-only database. You cannot create your own database views (CREATE VIEW ...). To create views, you have to set up your own local database and import PATSTAT data from its CSV files. But in almost all cases you can just work around database views: Here is a query which returns ...

Re: PATSTAT 2017 Autumn - text search operators and non full-text Index table error

I suppose you are using PATSTAT Online. PATSTAT Online is powered by MS SQL Server, which is using the T-SQL dialect of SQL. There are some more wildcards than just the %-character. Please see the full Microsoft documentation here: https://docs.microsoft.com/en-us/sql/t-sql/language-elements/like-tr...

Re: EPO patents designated in single European countries

Dear Carmen, There probably is a misconception about the meaning of "designated states". Article 79 of the European Patent Convention (http://www.epo.org/law-practice/legal-texts/html/epc/2016/e/ar79.html) specifies since late 2000 that "All the Contracting States party to this Convention at the tim...

Please note that in the current 2017 Autumn Edition values in attribute NPL_BIBLIO of table TLS214_NPL_PUBLN can be up to 3 800 characters long. If your DB schema is not prepared to hold such longs strings, then you might experience problems when loading the data into your database. To avoid similar...

Re: Cpc classification

Hi, CPC classification codes are always used on the group level, like 'Y02E 20/16', so they contain 11 or more characters. Your code sample cpc_class_symbol in ('y02B', 'y02c', 'y02e') is equivalent to cpc_class_symbol = 'y02B' OR cpc_class_symbol = 'y02c' OR cpc_class_symbol = 'y02e' Strings of dif...

Re: Searching for help concerning PATSTAT query

Hi, in your second query of our previous post you are mixing ANDs and ORs. You can do that, but you have to be careful on how SQL interprets this (see https://docs.microsoft.com/en-us/sql/t-sql/language-elements/operator-precedence-transact-sql . Ist much safer to explicitely control the order of ev...

Re: Annual Amount of Pat Family Applications by Country of O

Hi deef, Your query looks fine. You are counting all families where first filings have an applicant of a certain country published by one of its publications. There is a slight difference to your earlier query, where you counted families which have family members (i.e. applications) whose most recen...
