Answer to the question: "

When are the annuity fees due?

The annuity fees are due annually on the filing date of the European patent (or the international filing date for the Euro-PCT application). This means that the first annuity fee in Norway is due on the first anniversary of the effective filing date after the date of publication of the mention of grant of the patent.
