摘　　要：在专利文件中,请求保护的产品权利要求有时会采用各种理化参数来进行限定,该类权利要求在化学、化工等领域较为常见。在实质审查、以及复审无效程序中,对此类权利要求的新颖性和创造性的审查,一直属于审查的难点和争议焦点,且在实审、复审和无效环节中的考察重点有所不同。本文从专利审查指南的一般规定出发,重点讨论在无效程序中如何对此类型权利要求的新颖性进行审查,旨在梳理无效程序中的审查思路和操作方法,以供借鉴。In patent documents, sometimes the product claims requested to be protected may include physical/chemical parameters, and such kind of claims are especially common in chemistry/chemical engineering fields. In substantive examination of patent, examination of requests for reexamination and for invalidation, the examinations of novelty and inventive step for such claims are always difficult and controversial issues, and have different emphosis in these different procedures. This article is based on the provisions in Guidelines for Examination, trying to discuss how to examine novelty of product claims including physical/chemical parameters in invalidation procedures, so as to establish reference for logical thoughts and methodology.
