French to English Law/Patents

The abbreviation appears beside a name on a court stamp. It reads as follows:

pour communication conforme
p.o.l. (NAME OF CLERK)
Greffère de chambre

No search has rendered any possible translations or explanations as to the abbreviation (I've done searches in the Acronym Finder, Google, Eurodic...).

P.S. - The court is Swiss.

TIA,
