碩士 === 國立中央大學 === 產業經濟研究所 === 104 === This paper is aimed to conduct an empirical analysis of the litigation behavior of non-practicing entities (NPEs) from patent auction hosted by Ocean Tomo. In order to consider the excess zeros of litigation cases of patents owned by NPEs, we adopt a zero-inflated poisson model to implement empirical estimations. The empirical results indicate that patent quality has positive effect on the number of patent litigation cases. We also find that litigated patents positively associated with the trading numbers of the patents. Finally, the empirical results of our paper support the crucial conclusion that NPEs tend to obtain patents with higher quality, and then file lawsuits against defendant companies by claiming that their products infringes on the patents of NPEs.
