稀土永磁材料产业专利导航数据

申请登记的数据以我单位利于检索表达式从国家局官方发布的数据中提取的数据为基础，经过专利权人合并、去噪、标引，共加工出稀土永磁材料产业关于稀土材料回收再生、加工及应用三个领域的专利数据形成数据集合

This dataset is developed from applied and registered patent data. The initial data was extracted from the official datasets published by the national intellectual property authority using retrieval expressions customized for our institution. After undergoing processing steps including assignee consolidation, denoising, and indexing, the processed data forms a dedicated patent dataset covering three key fields of the rare earth permanent magnet material industry: rare earth material recycling and regeneration, processing, and application.
