Enforcement struggles refer to the challenges and difficulties faced in protecting and upholding trademark rights, particularly when it comes to distinctive marks like sounds and scents. These struggles often arise due to the subjective nature of what qualifies as a recognizable mark, the variations in legal standards across jurisdictions, and the complexities of proving distinctiveness or non-functionality. The unique characteristics of sound and scent marks further complicate enforcement, as their intangible nature can make it harder to establish clear infringement.
