新能源汽车电池行业发明专利价值分析数据

对新能源汽车电池行业国内发明专利数据检索分析，了解专利价值情况并划型，有利于了解该项技术发展趋势及核心技术，避免企业重复研发或侵犯他人的知识产权。通过第三方数据库关键词等进行检索并筛选，算法规则：a.专利有效期得分，数据下载日至预估到期日年份数，每年得1分；b.发明人数量得分为发明人人数，每有1人得1分； c.代理机构情况得分，有为5分，没有为0分； d.被引用次数得分，每被引用1次+10分； e.同族专利数，每多一个其他同族专利+1分，以1个为基准； f.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；g.转让次数，每被引用1次+5分。a+b+c+d+e+f+g=分数，根据分数划分为无价值、一般价值、中等价值、高价值专利。Retrieval and analysis of domestic invention patent data in the new energy vehicle battery industry, aimed at evaluating patent value and classifying patents, helps to grasp the technological development trends and core technologies of this field, and enables enterprises to avoid redundant R&D and intellectual property infringement. Retrieval and screening are conducted via keywords from third-party databases, with the following algorithm rules: a. Patent validity score: The number of years from the data download date to the estimated expiration date, with 1 point awarded per year; b. Inventor count score: The number of inventors, with 1 point awarded for each inventor; c. Agency status score: 5 points if a patent agency is involved, 0 points otherwise; d. Citation count score: +10 points for each citation received; e. Family patent count score: +1 point for each additional family patent beyond the baseline of 1; f. Claim count score: Taking 10 claims as the baseline, subtract 1 point for each fewer claim and add 1 point for each additional claim; g. Transfer count score: +5 points for each patent transfer; The total score is calculated as a+b+c+d+e+f+g, and patents are classified into non-valued, general-valued, medium-valued, and high-valued patents based on the total score.
