摘要
随着中国栗产业的迅速发展,栗相关专利的数量也逐年增加,鉴于专利对研究领域具有重要的借鉴和促进作用,笔者对1986—2010年间中国栗相关专利进行文献计量分析。结果表明：栗相关专利申请量15年间增涨15倍以上;主要专利类型为发明专利和实用新型专利,占96.85%;专利平均授权周期为1~4年;50%以上专利有效期年限超过5或10年;专利内容主要为农业和食品轻工领域,占79.13%;专利权人类型主要为个人,占66.42%;专利研究热点地域为河北、浙江、北京、山东、湖北。预计未来专利申请热点是栗果功能食品开发及生产废弃物的综合利用。
With the Chinese chestnut industry developed rapidly, the numbers of patents relating chestnut had increased year by year. In view of these patents importance for chestnut research field, the data of national patents relating chestnut in 1986-2010 were calculated by using the statistical method.
