叶片风机专利分析数据

叶片风机专利分析数据主要包括了全球专利数据库中有关叶片风机的专利数据，并根据自有算法对专利数据进行了统计，确认重点专利，可用于横向、纵向了解叶片风机全球专利数据的变化情况和技术发展趋势，了解各国和各地区企业/个人的技术创新能力、创新水平差异，为企业提供研发合作、技术引进或输出建议。1、采用统计学模型排序、聚类的方法，对专利数据的著录项目进行统计。包括以下：1.数据来源：全球专利数据库；2.数据采集：根据专利的IPC分类号和关键字段，筛选全球专利数据库中的叶片风机相关专利，记录著录项目信息，形成叶片风机的专利数据库；3.重点专利筛选：专利的重点程度定义由被引用专利数量和简单同族数量确定，即专利重点程度Y=X1+X2，其中X1表示被引用专利数量，X2表示简单同族数量；确认每个专利的重点程度之后，取重点程度值大小排序在前20的专利作为重点专利，标注为是，反之标注为否，具体采用了IF、RANK的组合函数。

The blade fan patent analysis dataset primarily consists of patent data related to blade fans sourced from the global patent database. It conducts statistical processing on the patent data using a proprietary algorithm to identify key patents. This dataset can be utilized to gain both horizontal and vertical insights into the changes and technological development trends of global blade fan patent data, as well as the disparities in technological innovation capabilities and innovation levels between enterprises and individuals across different countries and regions, providing enterprises with actionable recommendations for R&D cooperation, technology introduction, or technology export.

1. Statistical sorting and clustering models are adopted to perform statistical analysis on the bibliographic items of patent data, which includes the following components:
1. Data Source: Global Patent Database;
2. Data Collection: Screen patents related to blade fans from the Global Patent Database based on patent IPC classification numbers and key fields, record their bibliographic information, and establish a dedicated blade fan patent database;
3. Key Patent Screening: The importance level of a patent is defined by the number of cited patents and the number of simple patent families, i.e., the patent importance score Y = X1 + X2, where X1 represents the number of cited patents and X2 represents the number of simple patent families. After calculating the importance score for each patent, the top 20 patents ranked by their scores are selected as key patents and marked as "Yes", while the remaining patents are marked as "No". A combined function of IF and RANK is specifically employed to implement this screening workflow.
