【美国专利申请常见问题】收到审查意见通知书(OA)后,申请人需在多长时间内答复?逾期未答复会怎样?
Time: 2026-03-09 Click count: 921

美国专利审查意见通知书(OA)的答复期限因通知书类型不同有差异,且存在延期空间,逾期未答复的核心后果是专利申请被视为放弃。


Part.1

不同类型 OA 的答复时限

①限制要求通知书:这类通知书用于要求申请人将申请限定在某一项发明,答复期限为发文日起 2 个月,若需延期,多可延长 4 个月,但要缴纳对应的延期费用。

②非终审查意见(Non - final Office Action):这通常是实审阶段的首封审查意见,会指出申请中存在的问题,答复期限为发文日起 3 个月。若无法按时答复,多可延长 3 个月,同时需支付相应延期费,终答复时间不得超过发文日起 6 个月的法定长期限。

③终审查意见(Final Office Action):当申请人对非终审查意见的答复未解决所有问题时,审查员会下发此类通知书。其答复期限同样为发文日起 3 个月,多可延长 3 个月,终答复截止时间也不能超出发文日起 6 个月,超期答复需缴纳延期费。此外,若对该意见的答复仍未获授权,后续收到的劝告书(Advisory Action),答复期限需沿用终审查意见的发文日起算期限。

Part2

逾期未答复的后果

①申请被视为放弃:依据美国专利法及相关规定,若申请人未在规定时限内提交可被接受的答复,其专利申请将被视为自动放弃。这种情况下,申请流程彻底终止,申请人此前为专利申请投入的时间、研发及申请成本都可能付诸东流。

②丧失关键权利与时间节点:申请被放弃后,申请人会失去该申请的提交日期,若该申请依赖优先权,还可能连带丧失优先权相关权益。且重新提交相同或类似技术方案的申请时,可能因已公开等问题面临新颖性不足等新障碍。

③补救难度大且成本高:即便有补救途径,申请人需提交恢复申请的请求,同时缴纳高额的恢复官费,还需充分举证逾期是因不可抗拒的事由或非自身故意的疏忽导致。但这种恢复申请并非必然通过,存在被专利局驳回的风险,进一步增加了专利申请成功的不确定性。
