Intellectual property rights are territorial prohibiting rights. You can therefore prohibit third parties from engaging in any activity based on your intellectual property rights in a country in which you have a prohibiting right, such as the use of your trademark or the manufacture and sale of products protected by a patent or registered design.
In addition, own intellectual property rights can be helpful if you are attacked based on intellectual property rights of a third party. Instead of a possibly protracted and expensive legal dispute, own intellectual property rights offer the possibility to bring them into out-of-court negotiations, for example in order to negotiate a mutual license.
Furthermore, own intellectual property property rights can be an indicator for particularly innovative companies and can be recognized in their value.
