从PCT申请和三方专利指标评价中国海外专利申请实力

目前中国的本国人发明专利申请量和授权量同时位居世界首位，成为名副其实的专利生产大国。但中国向海外申请专利的水平和实力还比较薄弱。从反映国家（地区）国际专利申请实力的PCT申请和三方专利这两个指标看，在绝对数量和规模上我国已进入国际前列，但在结构和强度上与主要专利强国还存在较大差距。我国政府将PCT申请量纳入规划文件后，除了推动和激励国内企业积极向海外提交专利申请，还要注意监测PCT申请进入国家阶段的状况，并为企业的海外专利布局提供必要帮助。

Research on the Strength of Chinese Overseas Patent Application Based on Indicators of PCT Applications and Triadic Patent Families

At present, China''s domestic invention patent applications and grants ranked first in the world. China has become a real patent producer. But the level and strength of China''s patent applications to the overseas is still relatively weak. From the two indicators of PCT application and triadic patent families which reflect the strength of national (regional) international patent application, China has entered the international forefront in absolute quantity and scale, but there is still a big gap in structure and intensity between the main patent powerful nations with China. Chinese government has set PCT applications into the planning documents. In addition to promoting and motivating domestic enterprises to actively file patent applications overseas, government should also pay attention to monitoring the status of PCT national phase entries and provide the necessary assistance for overseas patent layout.
