If the request is not filed and/or the examination fee is not paid in due time, the applicant will have 2 months from the notification by the Office to request examination and pay the fee alongside the surcharge. If the applicant doesn't request examination within 2 months, the application will be considered abandoned. However, an abandoned application may be reinstated within 6 months of the expiration of the term for making the examination request upon payment of the reinstatement and late examination fees. Within 12 months of the expiration of the term for making the examination request the application may only be reinstated if the applicant additionally establishes that the deadline was missed despite due care. It is also possible to request an accelerated examination under PPH.
