Re: Counting patents by IPC subclass

Dear PATSTAT user, Thanks you for your precise question. However, I doubt that your query ever worked. The error "Invalid column name 'ipc_subclass' " is in the GROUP BY clause. The attribute "ipc-subclass" does not exist in the database. It is just defined in the SELECT clause as an alias for "LEFT...

Hi Hanyang, The general recommendation we give in the relevant documentation "How to load PATSTAT data" (see bottom of page https://www.epo.org/searching-for-patents/business/patstat.html ) is this: When using MySQL: You must select character set utf8mb4 , because MySQL's character set utf8 is restr...

Re: Question: how to merge PATSTAT with Orbis

The HAN (Harmonized Applicant Name) attributes in PATSTAT are dervied from a public data set (see attachment for details) of the OECD - so all credits for HAN go to them. If the PATSTSTAT attribute HAN_HARMONIZED = 2, then the HAN_NAME should match with a name in ORBIS. But I do not have access to O...

Re: Download all retrieved applications in xml format!

Dear HZ, I do not see why you should not be able to download the abstracts selected by your query with the "Result table" download feature. Also, for retrieving only certain section of your result ("paging"), have a look at the option the ORDER BY clause of T-SQL provides: https://docs.microsoft.com...

Re: Download all retrieved applications in xml format!

Dear HZ, Thanks you for reporting this bug in the "Download Application" feature. We will fix it in a new version. In case another download format (CSV, Excel .xlsx, MS Access .accdb) would also work for you, then please note that there are several other download options available ("Download result ...

Re: PATSTAT Global

Hi , You are right. Not all legal events in the Category "R" ('PARTY DATA CHANGE') have the fields about old and new party populated. Currently - 2/3 of the attribute PARTY_OLD and - 3/4 of the attribute PARTY_NEW are populated. We provide the data as we receive them from the corresponding patent of...

Re: Question: How to effeciently retrieve in a same table with different timescale and different CPC number?

Dear HZ, PATSTAT Online and its 3rd party components unfortunately is not free of bugs. In certain complex queries (e.g. nested queries with aliases) it detects syntax errors where there are none. Often there is a workaround by slightly re-writing the query, like - what I did below - to replace "SEL...
