【日本专利常见问题】专利申请权可以转让吗?转让流程和注意事项是什么?
Time: 2026-03-20 Click count: 597
日本专利申请权(特許を受ける権利)可以自由转让,但必须向 JPO 办理移転登録(转让登记),否则不能对抗第三人。

Part.1

转让核心流程

1. 签订转让合同(Assignment)

合同必须为原件或公证认证副本,JPO 不接受普通复印件。

必备内容:

日本申请号(无申请号时用 PCT 号)。

转让人、受让人名称 / 地址(与 JPO 登记一致)。

转让人签字(至少)、受让人签字(建议)。

签署日期。

明确转让标的:申请权整体 / 部分 / 持分

2. 准备登记材料

移転登録申請書(JPO 官方表格)

转让合同原件 / 公证认证副本。

受让人委任状(Power of Attorney)(申请中案件仅需受让人;已授权专利通常需双方)。

名称 / 地址不一致时:同时提交表示変更登録申請。

企业转让:附法人登记事项证明书(公证)。

继承 / 破产:附继承证明 / 破产管理人资格证明。

3. 提交与缴费

提交方式:纸件邮寄 / 电子申请(JPO-Online)。

办理周期:

申请中案件:约2 个月(无官方通知)。

已授权专利:约2 周(有登记完成通知)。

4. 登记完成与效力

登记后在专利登记簿公示,对第三方生效。

未登记:转让仅在双方间有效,不能对抗善意第三人

Part2

关键注意事项

1、登记是生效要件

仅签合同≠完成转让;必须登记才产生对抗效力。

审查中案件:未登记前,仍以原申请人名义办理手续。

2、共有申请权转让

任何共有人转让持分,必须全体共有人书面同意。

未获同意的转让:无效,JPO 不予登记。

3、材料严格性

名称 / 地址必须与 JPO 登记完全一致,否则需先办变更。

签字:不接受电子签名,必须手写 / 实印。

外国主体:转让合同需公证 + 领事认证(视[敏感词])。

4、时间节点

无强制登记期限,但建议尽早办理。

需提复审 / 异议时:必须在提交前完成登记,否则手续可能被驳回。

5、跨境与 PCT 注意

PCT 进入日本前:优先在国际阶段完成转让,避免入国后复杂手续。

中国申请人:转让前不违反中国保密审查(先向中国申请或获保密审查同意)。

6、税务与合同

日本:转让所得可能涉及所得税 / 法人税,需合规申报。

合同条款:明确转让费、支付节点、技术交付、违约责任、税费承担。

Part3

常见情形处理

笔误更正:属表示変更,非转让;提交更正书 + 理由,无官费。

部分转让 / 持分转让:按一部移転 / 持分移転办理,单独缴费。

公司合并 / 分立:提交合并契约书 / 分立计划书 + 法人登记证明,按一般承継办理。
