专利创造性判断中克服技术偏见适用规则研究

Research on Applicable of Overcome Technical Prejudice in the Assessment of Non-obviousness of Patent

克服技术偏见是判断专利创造性时需要考虑的其他因素之一。但是由于克服技术偏见的认定条件较高,专利审查指南的规定较为概括,使得当事人、专利审查机关、法院未能对其形成细致而统一的认识,从而导致举证上的盲目和随意以及判定上的模糊和概括。在总结我国司法实践经验的基础上,结合欧洲专利局上诉委员会的认定经验,提出认定发明克服了技术偏见的三步判断方法,并对每个判断步骤所需的认定条件进行具体分析,以期明确克服技术偏见的判断路径和适用规则,便于当事人更具针对性的提出诉请和提交证据,也有利于专利审查机关和法院统一裁判标准及相关判断更合理、合法。

Invention overcomes technical prejudice is one of secondary conditions in the assessment of non-obviousness.However,due to the confirmation requirements for invention overcomes technical prejudice are very high,and the provisions of the patent examination guidelines are more general,which makes the parties,patent examination authorities and courts fail to form a detailed and unified understanding of it.On the basis of summarizing China’s judicial practice experience and combining with the confirmation experience of the Appeal Board of the European Patent Office,it proposes a three-step judgment method to assess whether the invention overcomes technical prejudice or not,and analyzes the confirmation requirements for each judgment step,so as to make the assessment methods and applicable rules of technical prejudice clear.It is convenient for the parties to bring claims and submit evidences more targeted,and promote the patent examination authorities and the courts to unify the judgment standards and save the judicial resources.
