七旬"发明大王"挺尴尬:因交不上年费 专利大多失效

2017-06-08 09:12:31   中国青年网

在70岁民间发明人董兰田的书架上,几十本专利授权证书整齐码放着,既有发明专利证书,也有实用新型专利证书,涉及的领域有制造、建筑、交通运输、能源、冶金、军事、机械等。从2004年董兰田退休以来,他个人报送国家专利局申请的专利有285项,其中有70%被授权,然而,成功转化的仅有40多件,转化率不足25%。

改造炉灶的发明,拥有国家专利局授权

2004年,58岁的董兰田从工厂退休,在一次探亲时,他发现液化气炉受热不均导致油花四溅,产生了改造的想法。

经过研究,他把对炉灶的改造写成了“封闭导流燃气烟道风门”实用新型专利申请,一系列材料申报和审批后,他拥有了第一个国家专利局授权的实用新型专利。

除了日常生活中的发现,他大多通过读报、看电视寻找灵感,“2008年,我看电视,发现考古人员进行文物发掘时是露天的,就想能不能做一个无支柱大棚,可以抵挡风吹日晒雨淋,就设计了‘大跨度无支柱悬索吊顶技术与应用’,没想到竟然被航空部门看中了”,董兰田说,他原本学医,退休后在专利申请时涉及的领域十分广泛,“制造、建筑、交通运输、能源、冶金、军事、机械等等,我都有涉及,只要抓住问题的核心提出解决方案就行”。

退休以来,董兰田个人申请专利数达285项,其中包括144项发明专利和141项实用新型专利。

因未交年费,85%的专利已失效

董兰田退休至今,有207项专利获得授权,85%以上因未交年费已失效。“这些年的我个人申请的专利,有些不交年费已经放弃所有权了,目前手里还有50多个专利”,董兰田拿出一份“有效专利目录”,其中有21项专利被授权,另有31项专利处于在审阶段。

13年来,他个人申请的专利大约有40项成功转化,“不到授权专利的1/4”,董兰田说,“因为曾经到一些企业去帮他们解决问题,圈子里不少人知道我,所以转化出的专利多一些,印象中全国民间发明人的专利转化率不足10%”。

像董兰田这样的民间发明人还有很多。50多岁的王六祥在工作之余就热衷于发明创造,多年来王六祥共申请了3个专利,目前获得授权的只有一项。

“全能”民间发明人的尴尬

山东省知识产权局官方网站发布的2016年全省专利情况通报显示,全省国内发明专利申请量88359件,发明专利授权量19404件,同比增长15%,全省企业发明专利授权量达到10816件,全省高等院校发明专利授权量达到3637件,全省科研院所发明专利授权量达到903件。山东省知识产权局一工作人员说,“暂时没有关于职务发明与非职务发明数目的统计,从专业性等各个方面来说,职务发明获得授权的几率更高”。

为何民间发明人专利转化率低?山东发明协会秘书长李先生说,目前企业发明转化率最高,因为发明与企业实际生产息息相关,另外,发明人不知道企业需要什么,他们发明的东西企业用不上,这就造成了专利无法转化的局面。“2006年11月,我们上线了交易中心,发明人可以主动申请将自己的专利和联系方式在我们网站公开,有相应需求的企业或单位会与之联系”,济南市知识产权局专利实施处一工作人员说。
