According to the Canadian Intellectual Property Office (CIPO), fee waivers and refunds are possible under certain circumstances. For example, if a fee was paid twice in error, CIPO can refund the overpayment. Additionally, if an applicant can prove that they are unable to pay the fees due to financial hardship, they may be eligible for a fee waiver. However, the criteria for financial hardship are strict and require a detailed explanation and supporting documents. It is also important to note that not all fees are eligible for a waiver or refund. Applicants are advised to consult the fee schedule and the relevant Practice Notice on fee waivers and refunds on the CIPO website for more information. Find out more here.
