从专利申请看科技发展趋势

美国专利那些事儿 同期发布的还有进5年来专利申请的趋势。

这篇文章里还提到了Top 10 Fastest Growing Technologies十大增长最快科技

前提需要先了解一下专利分类规则：Cooperative Patent Classification (CPC)
最上层包括——

• A: Human Necessities
• B: Operations and Transport
• C: Chemistry and Metallurgy
• D: Textiles
• E: Fixed Constructions
• F: Mechanical Engineering
• G: Physics
• H: Electricity
• Y: Emerging Cross-Sectional Technologies

例如，一个专利属于："A01B33/00" (which represents "tilling implements with rotary driven tools").

• Section (one letter A to H and also Y)
• • Class (two digits)
• • • Subclass (one letter)
• • • • Group (one to three digits)
• • • • • Main group and subgroups (at least two digits)

对应的A01B33/00表示——

• Section A
• • Class 01
• • • Subclass B
• • • • Group 33
• • • • • Main group 00
