来了~专利年费之(加拿大)篇

Kangxin Partners PC | English | AcademicThink | Sept. 18, 2025 | UndeterminedIP Protection

加拿大专利的保护期限为自申请日起20年,专利权人需每年缴纳年费(维持费)以保持专利有效。年费从申请日起第2年开始缴纳,缴费截止日期为申请日的周年纪念日。未按时缴纳年费可享有6个月的宽限期补缴,但需支付滞纳金。年费可提前最多12个月缴纳,建议在截止日前3个月内完成。加拿大知识产权局(CIPO)不会主动提醒缴费,专利权人需自行或委托代理机构监控。

年费标准根据专利年限和申请人类型分为小型实体和标准实体两类,2025年的年费费用有具体分档,且小型实体需提交符合资格的声明。逾期缴费需连同滞纳金一并缴纳。若宽限期结束仍未缴费,专利失效,权人可申请恢复,有严格的申请期限、费用和材料要求,且恢复成功率较低,审批时间较长。

专利权人可通过加拿大知识产权局官网查询专利法律状态及年费缴纳记录。查询时需访问CIPO官网,使用专利号、申请号或关键词搜索专利信息。申请阶段同样需缴纳年费,缴费后不可退款。对于通过国际专利申请(PCT)进入加拿大的专利,年费缴纳时间应根据首次申请日计算。

专利权人应及时监控年费缴纳期限、确认实体类型、保存缴费凭证,避免因逾期导致专利失效或增加费用。合理管理年费缴纳是维持专利权持续有效的重要措施。文章末尾提供了专业年费代缴服务的联系方式。
