The official Swiss patent application is published on The patent applicant receives the published application by post.


A Swiss patent application will not be published if either:

  • a Swiss patent has already been granted and published within the 18 months period after the priority date as part of an accelerated substantive examination


If in doubt, treat your invention confidentially until it has been disclosed. This gives you flexibility with regard to possible subsequent applications.
