活塞环发明专利价值数据

根据自定规则对活塞环专利数据进行检索分析，了解活塞环发明专利情况，有助于活塞环成果转化，也有利于了解活塞环技术发展趋势及核心技术，有助于企业避免重复研发及侵犯他人的知识产权。数据来源：中国专利数据库中有关活塞环发明的专利数据。算法规则：本数据基于 AHP 模型，从专利有效期、发明人数量、代理机构情况、被引用次数、引用次数、同族专利数、权利要求数以及诉讼案件数八大价值维度，赋予相应的系数，并将八类价值之和定义为专利综合价值，利用IFS函数对专利进行价值判定，用于评价现有专利价值，为本领域技术人员、市场主体、成果转化机构提供技术支撑。算法规则包括：1.专利有效期得分为今日（数据下载当天即2023年11月22日）至预估到期日（预估到期日在今日之前的，仍以原公式计算，虽然可能此项分数为负分，但是专利到期后仍具有价值）年份数，每年算1分； 2.发明人数量得分为发明人人数，每有1人算1分； 3.代理机构情况得分，有为5分，没有为0分； 4.被引用次数得分，每被引用1次+10分； 5.引用次数，每引用1次+2分； 6.同族专利数，每多一个其他同族专利+1分，以1个为基准； 7.权利要求数，以10条权利要求为基准，每少1条-1分，每多1条+1分； 8.诉讼案件数，每有一次诉讼案件+50分。 最后得出来的分数取整，即四舍五入。Retrieve and analyze piston ring patent data based on custom rules. Understanding the invention patents related to piston rings helps promote the commercialization of piston ring technological achievements, grasp the technical development trends and core technologies of piston rings, and enable enterprises to avoid redundant R&D and intellectual property infringement. Data Source: Patent data related to piston ring inventions from the China Patent Database. Algorithm Rules: This algorithm is based on the AHP (Analytic Hierarchy Process) model, which assigns corresponding coefficients to eight value dimensions of patents: patent validity period, number of inventors, patent agency situation, number of citations received, number of citations made, number of patent families, number of claims, and number of litigation cases. The sum of the eight value dimensions is defined as the comprehensive patent value, and the IFS function is used to determine the patent value. This method is used to evaluate the value of existing patents, providing technical support for technicians in this field, market entities and achievement transformation institutions. The specific algorithm rules are as follows: 1. Patent validity period score: The score is calculated as the number of years from the data download date (November 22, 2023, today) to the estimated expiration date. If the estimated expiration date is before the download date, the original formula is still applied for calculation. Although this score may be negative, patents still hold value after expiration, with 1 point awarded per year. 2. Number of inventors score: The score equals the number of inventors, with 1 point per inventor. 3. Patent agency situation score: 5 points if a patent agency is involved, 0 points otherwise. 4. Number of citations received score: +10 points for each citation received by the patent. 5. Number of citations made score: +2 points for each citation made by the patent. 6. Number of patent families score: +1 point for each additional patent family beyond the baseline of 1 patent family. 7. Number of claims score: Taking 10 claims as the baseline, -1 point is awarded for each fewer claim, and +1 point for each additional claim. 8. Number of litigation cases score: +50 points for each litigation case involving the patent. The final score is rounded to an integer.
