重复授权专利是指两个以上内容相同的发明创造经过申请后均被授予专利权。重复授权专利与从属专利的区别在于,前者是两个以上的专利在技术内容上完全相同;后者是在后专利技术上比在前专利更先进,其实施又有赖于前一专利。一、重复授权专利的产生实践中,重复授权专利多为实用新型专利。从申请方面看:(1)由于信息不灵或不重视信息的作用,致使重复研究开发的项目较多。当两个以上相同领域的个人或者单位分别研究同一内容的技术,取得成果后,便可能各自申请专利;(2)两个以上的个人或者单位共同搞出的一项发明创
Repeatedly authorizing a patent means that two or more inventions that have the same contents are granted patent right after application. The difference between duplicate patents and subordinate patents is that the former is that two or more patents are identical in technical content; the latter is more advanced in post-patented technology than the previous one, and its implementation depends on the previous patent. First, the duplication of authorized patents In practice, duplication of patents are mostly utility model patents. From the application point of view: (1) due to the information is not working or not the role of information, resulting in more research and development projects more. When two or more individuals or units in the same field study the same content technology separately and obtain the result, they may each apply for a patent; (2) An invention made jointly by two or more individuals or units
