半挂车领域专利数据集

申请登记的数据以我单位利用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，加工出半挂车领域关于厢式半挂车、低平板半挂车、牵引车头、牵引车、压裂液五个领域的专利数据。

The data for application registration is based on patent data extracted by our organization via retrieval expressions from official data published by the national intellectual property bureau. After undergoing patent assignee consolidation, denoising and indexing, the processed data forms patent datasets covering five subfields in the semi-trailer sector: box semi-trailers, low-bed semi-trailers, tractor heads, towing tractors, and fracturing fluid.
