Many firms own a large number of patents, but just little ones can create their maximum financial capital through realizing the value of patents. Thus, how to transform the intellectual property capital into physical financial capital is an important issue of study for companies concerned with management performance. This study proposes an analysis approach, named Patent Priority Approach (PPA), based on patent priority from the company’s internal viewpoint. The approach initiates the steps of data search in the disputed patent, building the dataset from its patent family members, using the relation of claiming and be claimed of the priority patents when constructing the patent priority network. Therefore presents algorithms for critical chain, significant chain and core patent candidates. We illustrated the concepts and applications of PPA with the case of a medical device firm. Integrated the aforementioned information, the company’s patent portfolio strategy can be analyzed, evaluated, and predicted systematically. In addition, the market value can be realized to improve management performance. The conclusion of portfolio approaches and applications will provide insights for managers.
