从专利申请看科技发展趋势

link on JianShu

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
