Hi everyone,

I've come across the following: When downloading the .ZIP of a patent from the European Publication Server, the name of the .pdf and .xml of the patent is changed to EPxxxxxxxNWxx. Why is the "NW" added to the name of the patent? Is there a specific reason? When going through a bunch of .zips, it's quite an effort to always add the "NW" in order find a specific patent document.

Thanks a lot!

For the publication of corrections, the kind codes used by the EPO are A8 A9 B8 and B9 and there could be for example multiple A8 for a given application.

For example, EP3817295 (application EP20824052) has 3 publications: one A1 and two A8 that can be differentiated with a correction code:

EP20824052W1A8 for the first correction published on 2021/07/07
EP20824052W2A8 for the second correction published on 2021/08/25

The default value of the correction code for other kind codes is NW
