Non-entitlement to right to priority 

A European patent application has no right to priority if:

the application was not filed within the twelve-month period referred to in A‑III, 6.1(iii) and the applicant has neither:
corrected the priority date on time (see A‑III, 6.5.2), such that the date of filing of the European application no longer exceeds the twelve-month priority period under Art. 87(1) or that the priority date is no longer the same as the date of filing (see A‑III, 6.6), nor
successfully requested re-establishment of rights in respect of the priority claim (see A‑III, 6.6)
the previous application did not seek an industrial property right giving rise to a priority right (see A‑III, 6.1); or
the previous application does not give rise to a priority right in respect of the state, WTO member or industrial property authority in or for which it was filed (see A‑III, 6.1(i) and 6.2).
