与世界其他国家相比,中国的实用新型制度具有中国的特色。其一是实用新型专利申请提交后只需通过初步审查(不经过实质审查)即可被授予专利权,而其权利与经过实质审查的发明专利无实质性区别,只是保护期仅为10年;其二是申请人就同一件发明创造在申请实用新型专利的同日还可以申请发明专利(即“一案两请”)。一般情况下实用新型会先获得授权,其后当发明专利申请即将获得授权时,申请人只需放弃在先获得的实用新型专利权即可,从而使该发明创造的专利权得以延续。
Compared with other countries in the world, the utility model system in China has Chinese characteristics. First, a utility model patent application can be granted a patent right only after a preliminary examination (without substantive examination) after it is submitted, and its rights are substantially different from substantively examined invention patents, only the protection period is only 10 years; The second is that the applicant can apply for invention patent on the same day of applying for a utility model patent (ie, “two cases”) on the same invention creation. Under normal circumstances, the utility model will be authorized first, then when the invention patent application is about to be authorized, the applicant only needs to relinquish the previously obtained utility model patent right so that the patent right created by the invention can be renewed.
