There has been another update this week. The new release contains all EP publications from 1978 (publication number 1) to week 37 of 2020.

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...

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...

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...

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 ...

Dear HZ, The data on which PATSTAT Online is based is also available as bulk data for download and import into your own data base management system. It is a subscription product. If you just need a single edition, PATSTAT Global (worldwide patents) currently costs 975 EUR and PATSTAT EP Register (on...

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...

Thank you, Rudi, for this proposal. I will consider in in the next version. The SHA-1 you mentioned is created automatically by our Bulk Data Platform from which you can download EPO data. But generally, SHA-1 is used less and less. So for additional check sums we will utilize the more future-proof ...

Dear Rudi, Thanks for your suggestion. Please find in the attached file the requested check sum data. SHA512_for_PATSTAT_files.zip BTW: I personally use the free 7zip tool (with command line interface) a lot to unzip archives.. Like WinZip, it sometimes has issues, but in some cases it is useful to ...
