What is the deadline for submitting an Examination request? Can this deadline be extended?

In Russia: The substantive examination shall be requested before expiration of the 3 years period from the international filing date. A two-month extension of the deadline is available.

In Eurasia: Substantive examination of a PCT application shall be requested at the filing as required by the Eurasian patent rules. If for some reason the request has been not filed, the EAPO will issue a corresponding notification and there will be two months for payment of the fees. In case the deadline is missed, the applicant’s rights can be reinstated within a year from the missed due date subject to payment of the restoration fees and providing reasons for omission.
