摘要
磷石膏作为一种固体废渣,通过专利评价的方法找到该领域的核心专利技术至关重要。本文建立了包括技术价值、经济价值、法律价值三方面的专利评价指标,运用突变级数法对磷石膏领域的专利进行评价。研究得出核心专利主要集中在磷石膏的综合利用和污染治理方面。同时,通过评价结果可以看出该领域的专利的申请数量虽为猛涨趋势,但高价值的专利较少,经济价值和法律价值方面尤为明显。
Phosphogypsum is a solid waste residue.It is very important to find the core patent technology in this field through the method of patent evaluation.This paper establishes patent evaluation indicators including technical value,economic value,and legal value.The catastrophe progression method is used to evaluate patents in the field of phosphogypsum.The research shows the core patents are mainly concentrated on the comprehensive utilization of phosphogypsum and pollution control.At the same time,through the evaluation results,it can be seen that although the number of patent applications in this field is rising rapidly,there are fewer high-value patents,especially in terms of economic value and legal value.
