The aim of this thesis is to describe the current legal regulations of covenant not to compete in the Czech Republic and the USA - particularly in the states of New York and California, to refer to the advantages and disadvantages of these regulations and to think if these very different regulations could inspire each other in some areas. I decided to write half of the thesis about covenant not to compete in the USA because of my study experience in American law school where I understood more closely the common law system of law and because I did not find any Czech article which would write about this topic in the USA and I wanted to fill in this blank space. This thesis is devided into three parts. The first chapter is dedicated to the current wording of covenant not to compete in the Czech Republic. In the particular subchapters there are described the constitutional roots of covenant not to compete, which activities can be banned by the covenant not to compete, which information the employee must have acquired, with what types of employess the covenant can be entered into and in what area scope, what is the maximum time period during which the employee can be banned, what compensation the employer has to pay to the employee and how the covenant can be terminated.

近年來頻傳科技業高階主管跳槽到競爭對手，而我國於二〇一三年增訂營業秘密的刑事責任，營業秘密的保護與人才流動兩者之間的關係，越來越受到關注，特別是台積電與梁孟松案，智慧財產法院於二〇一二年三月台積電訴梁孟松案假處分裁定採納不可避免揭露原則，在後續的判決中亦論及不可避免揭露原則，使此一原則開始受到國內智慧財產權法實務及學術界之相當關注。 不可避免揭露原則係源自美國法上之司法實踐，本文首先介紹美國法上不可避免揭露原則的理論基礎，透過五個重要判決（Allis-Chalmers v. Continental案、PepsiCo v. Redmond案、Bimbo v. Botticella案、Whyte v. Schlage案和EarthWeb v. Schlack案）介紹不可避免揭露原則的發展，分析不可避免揭露原則的要素，包括兩間公司的競爭程度、營業秘密之認定、員工職務的近似程度、違反誠信的行為和與保密協議、競業禁止條款的關係，並且整理出四種不同的適用類型即完全適用、擴張適用、限縮適用和拒絕適用，繼而以之分析美國各州的適用情形。最後，回歸到我國台積電訴梁孟松案，分析該案是否適合導入或參考美國法之不可避免揭露原則之各項考量因素，並評析法院對於不可避免揭露原則的見解包括採納不可避免揭露原則的適用類型，輔以我國目前實務發展，探討不可避免揭露原則是否應該引入我國，包括是否違反我國法律規定、與美國法制的差異是否影響不可避免揭露原則的適用和價值衡平與政策考量。 / In recent years, hi-tech companies in Taiwan occasionally need to cope with crisis where their executives decide to join competitors’ firms. Along with the 2013 amendment in Trade Secrets Law, which crminizlized trade secrets infringemenet, the relationship between the trade secret protection and job mobility has drew wide attention from IP practitioers and academia. In the case of TSMC v. Liang, the Intellectual Property Court first applied the inevitable disclosure doctrine in an injunction relief. Since the inevitable disclosure doctrine originates from the judicial development of the United States (U.S) trade secret law, the thesis first introduces the basic idea of the inevitable disclosure doctrine in the U.S., and then through five representative cases, including Allis-Calmers v. Continental, PepsiCo v. Redmond, Bimbo v. Botticella, Whyte v. Schlage, and EarthWeb v. Schlack. It then investigates the overall development of the inevitable disclosure doctrine in the U.S.. Based on the case-law development, the thesis further analyzes the essential factors of the inevitable disclosure doctrine incluing the competition between rivals, indentification of trade secrets, job similarity, dishonest act and the relationship with non-disclosure agreement and covenant not to compete. It also catalgorizes four types of judicial application of the inevitable disclosure doctrine, including the original, extended, limited and rejected type. Furthermore, the thesis analyzes the type of application of the inevitable disclosure doctrine in each state in the U.S.. Last but not least, back to TSMC v. Liang, the thesis analyzes if the above-mentioned factors of the inevitable disclosure doctrine fit in the case, and reviews the court ruling about the inevitable disclosure doctrine. In conclusion, based on the current development of judicial practice, the thesis assesses the application of inevitable disclosure doctrine in Trade Secrets Law in Taiwan with the polict goal to balance various interests.
