專利除了能排除他人模仿技術生產商品，還能將技術商品化進行轉讓作為技術移轉策略。本文即探討專利權轉讓意願的決定因素，使用專利引用關係網路分析美國專利局1980年到2020年的太陽能電池專利，區分出核心專利與得出專利引用所衡量的特性，專利新穎性與專利影響力，研究結果發現核心專利會因專利申請人類型對於專利轉讓有不同影響，私人公司所申請的核心專利提高轉讓機率，而學校或研究機構所申請之核心專利降低轉讓機率。

Patents are used to be the fence for technology imitation. However, it is less noticed that technology transfer can also be expedited by patent assignment in the market. This article discusses the determinants of the willingness to patent assignment, uses the patent citation relationship network to analyze the solar cell patents of the United States Patent and Trademark Office dataset from 1980 to 2020 to distinguish core patents and derive the characteristics measured by patent citations - patent novelty and patent influence. We find that core patents have different effects on the willingness to patent assignment depending on the type of patent applicant. Core patents applied by firms increase the assignment probability, while core patents applied by schools or research institutions reduce the assignment probability.
