Template documentationFor adding country links to the template itself, see country codes at Template:Europe topic#Altering the link used for a specific entity.
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the |state= parameter may be used:
{{Patent offices in Europe|state=collapsed}}will show the template collapsed, i.e. hidden apart from its title bar.{{Patent offices in Europe|state=expanded}}will show the template expanded, i.e. fully visible.
