Important Notes on Patent Annual Fee Payment and Right Restoration

说明专利年费的缴纳规则、滞纳期与滞纳金计算方式,介绍专利权终止后的恢复条件与办理时限,提醒权利人建立年费管理机制,避免权利失效。

专利授权后并不是一劳永逸,权利人需要按年缴纳年费维持专利权有效。缴纳规则:年费自授予专利权当年开始缴纳,此后每年在上一年度期满前预缴;金额随保护年限递增,发明、实用新型与外观设计的标准不同,具体以国家知识产权局公布为准。滞纳期与滞纳金:期满未缴纳的,有六个月的滞纳期,滞纳期内补缴需要按超期时间加收滞纳金,比例逐月递增。权利恢复:因未缴年费导致专利权终止的,可以在规定期限内请求恢复权利,需要补缴年费、滞纳金与恢复费,并说明正当理由,恢复期限与条件以官方规定为准,超过期限则权利无法恢复,技术进入公有领域。管理建议:企业应建立专利台账,记录每件专利的申请日、授权日与年费到期日,设置多级提醒;专利数量较多的可以委托专业机构托管年费事务;转让或许可期间应明确年费缴纳责任的归属。风险提示:并购带专利的公司时,应逐件核查年费缴纳状态与法律状态,避免受让已终止的专利。具体年费管理方案可联系售司网顾问按实际情况评估。
