【美国专利申请常见问题】专利申请过程中,能否变更专利权的申请人(所有权人)?需要办理哪些手续?
Time: 2026-03-10 Click count: 898

在美国专利申请过程中,无论是处于审查阶段还是尚未授权的状态,均允许变更申请人(所有权人)。变更主要分所有权转移和权利人名称更正两类情况,两类情形办理手续依据 USPTO 规则有所差异,具体流程如下:


Part.1

准备核心证明文件

所有权转移场景:需准备书面的专利转让协议(Patent Assignment),该文件需由原所有权人签字,明确转移的专利申请相关权利范围,比如是全部权利还是部分权利。若涉及联合申请人,需所有联合申请人共同签字确认。若是因企业合并等特殊情形导致的所有权变更,还需额外准备合并相关的法律证明文件,以佐证变更的合法性。

权利人名称更正场景:若只是纠正申请人名称中的错别字、更新企业更名后的名称等不涉及权利转移的情况,需提交名称变更的证明材料,如企业更名的工商登记文件、个人姓名变更的官方证明等。同时要依据 37 CFR 1.46 (c)(1) 提交申请人名称更正或更新的请求。

Part2

填写并提交备案相关表单

申请人需通过 USPTO 的转让备案中心(Assignment Center)提交备案封面表,表单中要准确填写专利申请号、原申请人和新申请人的详细信息、变更类型等关键内容。若变更后申请人并非发明人,还需依据 37 CFR 1.46 (c)(2) 提交申请人变更请求,且需同时提交符合 37 CFR 3.73 (c) 规定的声明文件,确保变更流程符合相关法规要求。所有提交的证明文件需以黑白 TIFF 或 PDF 格式上传至系统

Part3

缴纳相应备案费用

办理申请人变更需缴纳对应的备案费用,具体费用金额可参考 USPTO 当期公布的费用标准,费用相关可对应商标服务费用代码 “8521” 的收费规则来确认缴纳金额,需在提交变更请求时按时缴纳,避免因费用问题导致变更备案失败。

Part4

等待备案结果反馈

提交申请后约 7 天内,申请人会收到 USPTO 发出的备案通知或未备案通知。若收到未备案通知,需根据通知中注明的原因进行补正,常见问题包括封面表遗漏关键信息、证明文件模糊不可扫描、表单信息与证明文件内容不一致等,补正后重新提交即可。

完成上述备案手续后,USPTO 会更新专利申请的相关所有权记录,变更后的申请人正式享有该专利申请对应的相关权利。
