In connection with industrial property rights, expert opinions play an important role in the evaluation of the given situation. The questions raised in this regard can therefore be extremely diverse. For example, an expert opinion may give an indication as to whether, as a result of the use by a third party, an infringement of one's own industrial property right exists or, as a result of one's own use, the scope of protection of an industrial property right of a third party is infringed. Apart from shedding light on the situation, an expert opinion can also serve to plan for a strategic approach.
