晶硅太阳能电池相关专利价值评价数据

数据包中主要包括了国内晶硅太阳能电池相关的专利，根据自有算法对专利数据进行了评价，可用于横向、纵向了解晶硅太阳能电池相关专利数据变化情况，有助于了解晶硅太阳能电池知识产权工作成果；通过现有专利价值的评估，帮助企业及早做好专利保护；了解晶硅太阳能电池的技术发展趋势，有助于企业避免重复研发，避免企业开发的技术侵犯他人的知识产权。1、数据采集：通过第三方知识产权检索网站，对国内晶硅太阳能电池相关的发明专利数量、实用新型数量、外观设计数量进行采集。2、数据处理：对采集到的原始数据进行处理，通过去除重复和有缺失的数据，对数据进行清理分类。3.数据计算：专利价值度评价模型采用层次分析法，基于层次分析（AHP）的主观赋值方法，对各个指标的主观确定权重，技术/法律/市场/战略/经济价值得分=∑各方面对应各个指标 * 对应权重，技术价值：被审查员引证数，引用专利国别数，引用非专利文献数，引证专利数，IPC部数，IPC小类数；法律价值：独权数、主权项数字数、权项数、说明书页数、布局国家数、PCT国际申请、存活期；市场价值：同族数、剩余有效期；战略价值：无效次数、ETSI标准、专利奖；经济价值：转让次数、许可次数、质押次数算；专利得分为五个方面的价值得分累加总和。利用IFS函数对专利进行价值判定，专利价值度=IFS(专利得分>45, "超高价值专利",专利得分>20, "高价值专利",专利得分>10, "一般价值专利",专利得分>0, "无价值专利",) ，为本领域技术人员提供研发决策依据和技术规避作优先参考。

This dataset mainly covers domestic patents related to crystalline silicon solar cells. The patent data is evaluated using a self-developed algorithm, which enables horizontal and vertical understanding of the changes in patent data related to crystalline silicon solar cells, and facilitates the understanding of the achievements of intellectual property work in the field of crystalline silicon solar cells. It helps enterprises to carry out patent protection in advance through the evaluation of existing patent values, and to understand the technological development trends of crystalline silicon solar cells, so as to avoid redundant R&D and the risk of infringing others' intellectual property rights for enterprises.

1. Data Collection: Relevant invention patents, utility model patents and design patents related to domestic crystalline silicon solar cells are collected via third-party intellectual property retrieval websites.
2. Data Processing: The collected raw data is processed by removing duplicates and incomplete records, followed by data cleaning and classification.
3. Data Calculation: The patent value evaluation model adopts the Analytic Hierarchy Process (AHP), a subjective weighting method, to determine the weights of each indicator subjectively. The scores of technical/legal/market/strategic/economic value are calculated as the sum of the value of each corresponding indicator multiplied by its corresponding weight, specifically:
- Technical value: Examiner citations, number of cited patent countries, number of cited non-patent literature, number of cited patents, number of IPC divisions, number of IPC subclasses
- Legal value: Number of independent claims, number of words in the independent claim, number of claims, number of pages in the specification, number of layout countries, PCT international applications, survival period
- Market value: Number of patent families, remaining validity period
- Strategic value: Number of invalidations, ETSI standards, patent awards
- Economic value: Number of transfers, number of licenses, number of pledges
The total patent score is the cumulative sum of the five-dimensional value scores. The patent value degree is determined using the IFS function: Patent Value Degree = IFS(Patent Score>45, "Ultra-high Value Patent", Patent Score>20, "High Value Patent", Patent Score>10, "General Value Patent", Patent Score>0, "No Value Patent"). This dataset provides R&D decision-making basis and priority reference for technology avoidance for technical personnel in this field.
