I'm participating in some EQE training and there is this question/answer:
Most fees for European patent applications cannot be paid before their due date. One exception is renewal fees, which can always be paid up to:
- Three months before the due date.
- Six months before the due date.
- One year before the due date.
Answer The correct answer is 1. Renewal fees for European patent applications may be validly paid up to three months before the due date. For the renewal fee for the third year, answer 2 is also correct. This special rule for the 3rd renewal fee was made to allow for the payment of this fee on entry into the regional phase (Rule 51(1) EPC, implementing Article 86(1) EPC).
While I can find a lot of stuff about the fees and so on I can't find any information about these three months. Where do I find them?
