本研究旨在瞭解究竟專利訴訟對整體企業績效在長時間下是否有直接的關係，以及究竟透過美國國際貿易委員會（ITC）或美國地方法院（USDC）的管道，何種對企業防禦專利侵權的策略較為有效。本研究樣本依據國家研究所之專利情報中心（STPI）之前三大智慧型手機製造商，以及透過美國智慧財產局（USPTO）、美國國際貿易委員會（ITC）、美國地方法院（USDC） 蒐集三家製造商2010年至2012年之間的使用臨時禁制令之專利訴訟案件次數，並以量化統計敘述統計、相關係數以及多變量分析方式分析探討究竟專利訴訟是否對企業績效有關聯及影響。統計結果是依據三大指標:市場價值（Market Value）、市場成長率（Market Growth）以及股東權益報酬率（Return on Equity）為基準，發現專利訴訟確實對公司的股價與市佔率造成影響，但對於其市場成長率並沒有明顯改變，反而對部分公司而言，如蘋果與三星，專利訴訟頻率與市佔率是正面相關的關係。因此，由此研究可得知，專利訴訟確實對行動裝置製造商的財務績效有影響，但也只是短期的衝擊。由此可見，專利訴訟對於行動裝置製造商的財務績效有短期的影響，建議製造商未來可將競爭策略著重於科技研發與技術層面，以利維持公司的財務績效。

This study is aimed to explore the relationship between patent lawsuits and corporate performance of famous mobile device manufacturers, Apple, HTC, Samsung, and Nokia. More precisely, this research studies if there is a relationship between the frequency of patent lawsuits and corporate performance measured by market value, market growth, and ROE of these manufacturers. The sample company of this study were the top four smartphone manufacturers listed on STPI(Science & Technology Policy Research and Information Center) and their patent lawsuits were collected from 2010 to 2012 listed on ITC and USDC. Descriptive statistics, Correlation, and ANOVA were employed to analyze the link and effects between these two constructs. The results indicate that, stock price, market share, did have a significant relationship with patent lawsuits cases; nevertheless market growth of some companies continued to increase desipte the climbing number of paten lawsuit filed on them. Thus, it can be concluded that patent lawsuits may have a certain impact on financial performance, but only for a temporary time.
