Seibert, Michal ; Malý, Josef (advisor)
Internet domains and legal protection of domain names are enjoying a rapid growth in awareness among businesses and individuals not only world-wide, but also in the Czech Republic. Undoubtedly it is the internet, what has been the biggest change in our lives in past 15 years. Originally a military project, which turned to be "something" more than anticipated. Internet alone is a brand new world and therefore there must be certain rules to run and to control it. Thanks to rapid improvement of connectivity, above all after broadband connections had been implemented with vast majority of citizens, this medium has become a mass medium and the law enforcement of rules has become more important and common. The goal of this diploma thesis is to create a view of field of internet domains and related law issues, above all concerning the protection of the names of domains. The essential part of the thesis is so called ADR part. It handles the way of resolution of disputes. Information in this thesis is based both on professional sources and on own experience which I gained with my internet projects or even with domain disputes. This document is not intended to be solely an academic text but also a practical guide that will help "everyday users" of internet. This diploma thesis is divided into theoretical beginning and then it focuses on practical law part. Chapters are made of sections which build together a complex overview of the field of law issues. In the end of the thesis there is described so called "ADR" with ".eu" domains. The whole law framework in the thesis is supplemented by real examples from real life and therefore the thesis has the ambition to improve the readers' (law) knowledge in this field.
