材料科学领域专利审查时有关创造性判断的技术分析 Technical Analysis about the Inventive Step in Patent Examination in Material Science Field

在国内外的专利审查中，创造性的判断一直是实质审查工作中的难点和争议点。本文通过材料科学领域的真实案例，从发明与对比文件的区别点、发明实际要解决的技术问题、对比文件给出的技术启示的判断以及预料不到的技术效果等方面对创造性的判断进行了技术分析，思考和总结了专利审查中有关创造性判断中需要注意的问题，有助于进一步全面、客观地进行创造性判断和审查，也为专利申请人和科技工作者撰写和申请专利提供参考和借鉴。 It is always difficult and controversial to estimate and evaluate the inventive step in patent examination all over the world. Through true patent cases in material science field, this article technically analyzed the inventive step from the differences between inventions and comparing files, objective technical problems of inventions that need to be solved, and technical inspiration and unexpected technical effects of comparing files. Thinking and summarizing issues of inventive step that might need attention in patent examination helped to further estimate and evaluate the inventive step generally and objectively. Some advices were proposed to provide references for patent applicant and scientific and technical workers’ composing and applying for patents.
