透明聚酰亚胺薄膜国内专利布局分析

Analysis on Patent Layout of Transparent Polyimide Film in Domestic Market

通过分析透明聚酰亚胺薄膜专利技术在国内市场的专利申请量、技术集中度、技术领域分布等布局情况,发现不同申请国家或地区的申请策略存在较大差异。虽然国内的研究机构、高校和企业在申请量方面与日本并驾齐驱,但是仍不能掉以轻心,要在不断加大研究投入的同时,注重国内的专利布局,避免日本和韩国以及其它国家或地区在国内透明聚酰亚胺薄膜领域形成技术垄断。

The numbers of patents, technical concentration, distribution of technical areas about the transparent polyimide film in the domestic market were analyzed and significant differences in the application strategies of different countries or regions were found. Although domestic research institutions, universities and enterprises had the same application amount with Japan, but they will still continue to increase research funding, at the same time, pay attention to the domestic patent layout, to avoid Japan and Korea and other countries or regions to form technical monopoly in domestic transparent polyimide film field.
