【大家都在关心】发明专利超过优先权期限,还能进入美国吗?
Time: 2025-04-02 Click count: 667

很多时候,当我们在进行知识产权布局时,往往很难一步到位做到及时和全面。当我们拥有一项可以申请专利的技术时,由于一些原因,错过了对外申请的佳时间,但又不想放弃这项技术在海外受到保护,占领市场的权利。

那么,有没有什么办法可以进行补救呢?

今天,以常见的美国发明专利申请为例,为大家解答一些大家在进行美国发明专利申请时的常见问题。

1. 通过巴黎公约向美国申请专利,优先权12个月;如果错过12个月优先权日期,那还有机会去美国申请专利吗?

答案是:有机会,可以在2个月内请求恢复进入美国,恢复理由:非故意,不需要提供任何证据证明;请求恢复需要和新申请一起提交。

2. 如果2个月恢复期也过了,那还有机会去美国申请吗?

答案是:还有机会,看下该案子早公开日是什么时候?(包括销售公开,申请公开,展会公开等),如果从早公开日算起,到现在为止还未超过12个月,那赶紧提交美国申请,美国有12个月宽限期,在早公开日起12个月内提交美国申请,申请人发明人自己公开的不会成为对比文件。

友情提醒:中国专利法有规定,非pct途径进入涉外[敏感词]阶段,需要通过中国的保密审查后方可去国外申请,所以要提前做好保密审查+请求DAS CODE优先权码。

3. 通过PCT向美国申请专利,如果错过30个月进入美国[敏感词]阶段的期限,咋办?

答案是:很好办,多花点钱就能搞定,PCT过期2年内,都可以向美国专利局请求恢复(恢复理由:非故意,不需要提供任何证据证明),即原本30个月期限+24个月恢复期=54个月内,都可以进入美国。

4. 申请人错过了12个月优先权期限,在2个月内提交了PCT申请+请求恢复优先权,这种情况下能进入美国吗?还需要再请求恢复吗? 

答案是:直接在PCT的30个月正常期限内进入美国即可,无需再请求恢复。
