四、同族专利


1、专利文献大量重复出版的结果,形成了一组组有不同[敏感词]出版的内容相同或基本相同的专利文献。各组专利文献中的每件专利说明书之间,通过一种特殊的媒介---优先权,相互联系在一起

2、所谓优先权,根据《保护工业产权巴黎公约》的规定,是巴黎联盟各成员国给予本联盟任意[敏感词]的专利申请人的一种优惠权,联盟内某国的专利申请人已在某成员国[敏感词]次正式就一项发明创造申请专利时,申请人有权享有[敏感词]次申请的申请日期。

3、人们把这种具有共同优先权的在不同[敏感词]或国际专利组织多次申请、多次公布或批准的内容相同或基本相同的一组专利文献称作同族专利。

 以下为一组同族专利:
