Notes

1. CIPO generally issues the filing receipt within approximately two weeks.

2. Filing to grant takes approximately 2–3 years, and the maximum term is 20 years.

3. If excess-claim or excess-page fees arise after formalities examination, the corresponding amounts must also be paid at grant. Additional attorney and official fees are charged as incurred. Late payment may incur a reinstatement fee; non-payment causes the application to be deemed withdrawn, and official and service fees are non-refundable.

4. Small-entity status generally requires fewer than 100 employees or university status. It is unavailable where the applicant is controlled by, or has assigned/licensed or is obliged to assign/license the invention to, a non-university entity with 100 or more employees. For PCT national-phase entry, eligibility must exist on the entry date; a divisional can claim small-entity status only if the parent qualifies. Otherwise, standard-entity fees apply.

5. All timeframes are subject to the authority’s actual examination progress; we make no guarantee regarding processing times.
