In the June 2012 issue of Managing IP, we reported on a novel calculation of application fees at the German PTO. While there was some ambiguity in the wording of the new law on costs in patent affairs, the legislator has now confirmed in proposed amendments to the law that, upon nationalisation of a PCT application, based on the number of claims as originally filed, fees must be paid for each claim in excess of 10 claims (€20/€30 for electronic/paper filing). Thus, for applications with a high number of original claims, substantial additional fees must be paid with no option for reduction by reducing the number of claims upon entry into the German national phase.
