The declaration of priority should preferably be made on filing, but can be made up to 16 months from the earliest priority date claimed. That is to say, items (i)-(iii) mentioned in A‑III, 6.5 can be supplied up to 16 months after the earliest claimed priority date. Where the priority claim is inserted after the filing date and causes a change in the earliest priority date, this 16-month period is calculated from that new earliest priority date in accordance with Art. 88(2).[Rule 52(2); ]

The applicant cannot request further processing in respect of the time limit for introducing a new priority claim under Rule 52(2), since it is excluded by Rule 135(2).
