[PIUG List] PCT publications with B1 suffix

Dear colleagues,

I recently conducted a search on Micropatent in which a PCT document WO
xxxxxxxxxxxx B1 was retrieved. Since then, every search has retrieved 2 or
3 of these documents. Can anyone explain what they are? I can't find
anything in the archives that explains the designation.

Regards,
