Abstract: To bring about high quality and high performance of patent technology development, great importance has been attached to study of patent valuation both at home and abroad. PetroChina Petrochemical Research Institute established a valuation system for oil refining and chemical patents on the basis of relative work procedures and evaluation indexes. This paper briefs about the key indicator content and standards as well as the concrete evaluation process. The process is tested to confirm the patents of synthetic rubber and polyolefin sectors in gradation and classification of oil refining and chemical patents and verified as effective and workable. Establishment and application of patent valuation system helps improve the company’s creativeness, brings about changes in patent management from quantity to quality, and promote effective development and industrialization of patent technology.

摘要： 为使专利技术开发有质量、有效益，国内外都十分重视专利价值的评估研究，中国石油石油化工研究院开展了具有评估专利价值功能和组织相关工作流程的炼化专利价值评估体系建设的探索，建立了评估指标体系，介绍了相关核心指标内容与标准以及具体评估流程，并在炼化专利分级分类管理中对合成橡胶、聚烯烃领域的专利进行实验验证，证明有效、可行。专利价值评价体系的建立与应用有助于提升企业创新能力，促进专利管理关注度由量向质转变，推动专利技术的有效开发和产业化。
