中国专利申请权和专利权转移数据简介

专利法律状态是指在某一特定时间点,某项专利申请或授权专利在某一国家的权利类型、权利维持、权利范围、权利归属等状态,这些状态将直接影响专利权的存在与否以及专利权权利范围的大小。专利法律状态主要类型之一是专利转让。专利转让是专利申请权人和专利权人把专利申请权和专利权让给他人的一种法律行为。中国单位或个人向外国人、外国企业或者外国其他组织转让专利申请权或专利权,必须经国务院有关主管部门批准。转让专利申请权或专利权的当事人必须订立书面合同,向国家知识产权局登记后生效。

CnOpenData中国专利申请权和专利权转移数据整理了专利申请权、专利权的转让情况, 包含专利ID、事务类型、公开日期、登记生效日、变更前专利权人、变更后专利权人、变更前申请人、变更后申请人等字段,以期为相关创新研究助力。
