This dataset is constructed by collecting data including patent applicants, legal status, technical subject classification, number of simple family members and other relevant indicators in the automotive crankshaft field. It mainly covers invention patents and utility model patents related to automotive crankshafts from the global patent database. The keyword "automotive crankshaft" is used to screen out patent data in the automotive crankshaft direction from the retrieved results, and the collected patent data is evaluated and classified using a proprietary algorithm. This dataset can be used to track the changes in automotive crankshaft-related patent data, helping to understand the achievements of intellectual property work in this field. By comparing the automotive crankshaft-related patent data of different enterprises or individuals, it is possible to analyze the differences in their technological innovation capabilities and innovation levels. Additionally, it can help understand the technological development trends of automotive crankshafts, enabling enterprises to avoid redundant R&D and the risk of infringing others' intellectual property rights.
1. Data Source: Data on invention patents and utility model patents related to automotive crankshafts from the global patent database.
2. Data Collection: The target layer of this dataset is patent technology relevance. The indicator layer divides the patent technology relevance index system into five value dimensions: market, technology, law, strategy and economy. Patents related to automotive crankshafts are retrieved, and the indicator layer is further decomposed into criterion layers as follows:
- Technical Value: Number of IPC classifications, number of cited patents, years of authorization
- Economic Value: Remaining effective years, number of pledge times
- Legal Value: Number of claims, number of document pages
- Strategic Value: Number of inventors, number of simple family members
- Market Value: Number of technical subject classifications, patent type, whether it belongs to strategic emerging industries
3. Data Analysis: This dataset is based on the Analytic Hierarchy Process (AHP) method, combining quantitative and qualitative analysis. The technical relevance is divided into three levels from high to low: A (high relevance), B (general relevance) and C (low relevance). The comprehensive scoring criteria are specified as follows:
- Level A: Strategic value ≥ 50 points, economic value ≥ 20 points, market value ≥ 50 points, legal value ≥ 60 points, technical value ≥ 30 points
- Level B: Strategic value ranges from 40 to 50 points (excluding 50), economic value ≥ 20 points, market value ≥ 30 points, legal value ≥ 70 points, technical value ≥ 30 points
- All other cases are classified as Level C
4. Data Application: Provide R&D decision-making basis and priority reference for technical avoidance for technical personnel in this field.
