基于专利新颖性研发组合标识图的技术机会分析——以溶栓药领域为例

Technology Opportunity Analysis Based on the Combination of Patent Novelty Research and Development——A Case Study of Thrombolytic Drugs

[目的/意义]识别新颖专利代替由一组关键词代表的专利空白,改善技术机会识别过于主观的缺陷。[方法/过程]利用一种基于系统流程的定量方法识别专利的新颖程度。通过基于密度的局部离群点(DLOF)算法识别出新颖专利,利用技术范围指标与同类专利数量指标构建研发组合标识图。[结果/结论 ]研究结果表明,基于专利的新颖性研发组合标识图可以准确地识别出新颖专利,为技术研发提供借鉴。

[Purpose/significance] The meanings of potential technology opportunities become more explicit by identifying anomaly patents rather than patent vacancies that are usually represented as a simple set of keywords. [Methods/Process] We propose an approach to detecting anomaly patents based on systematic processes and quantitative outcomes. Density-based Local Outlier(DLOF) algorithm is used to identify novelty patents, then use scope of technology index with amount of similar patents index structure Anomalyportfolio patent map. [Results/Conclusion] Research results show that novelty-focused patent mapping for technology opportunity analysis can accurately identify the novelty patents and provide a reference for the technology research and development.
