  • Amendments Introduced through Law No. 7101 on Arbitration Proceedings

These functions may aim to provide assistance to arbitration proceedings, such as collection of evidence through state courts, which would support the functions of the tribunal, or functions aimed at supervision of arbitration proceedings, such as set-aside actions.

  • Possibilities and the Results of Trademark Confusion

    Trademarks are the vehicles that are used to differentiate companies one from the other. They help to capture the consumers' attention. It is essential and necessary to protect trademarks that are created and improved with capital and effort, from unrightful use by third parties, and to prevent the encroachment of trademarks through confusion. One of the most efficient functions of intellectual property law is to encumber imitations, and to halt improper benefit by using the popularity of the trademarks to their consumers. On the other hand, in our daily lives, we often see trademarks that are similar, and may wonder how they co-exist at the same time. In this article, we will shed light on the reasons why similar trademarks can be registered, the criteria that cause trademark confusion, and the remedies to prevent and/or remove these infringements.
