What is the significance of the acronym IIRN in trademark applications?

The acronym IIRN stands for International Individual Registration Number, which is an essential element in the context of trademark applications. This number is assigned to trademarks that have been registered under the Madrid Protocol, an international treaty that facilitates the registration of trademarks in multiple jurisdictions through a single application. The significance of the IIRN lies in its role in identifying and tracking a specific trademark within the international registration system, ensuring that trademark owners can manage their rights effectively across different countries.

As trademark registrations can often be complex and involve navigating multiple legal systems, having a standardized identification number like the IIRN simplifies communication and administration in the global trademark system. This is particularly beneficial for businesses operating in various markets, as it provides a clear reference point for their trademark rights.

The other options do not accurately describe the function of the IIRN in trademark applications. There are no specific types of trademark registrations solely referred to as IIRN, nor does it relate to registration fee status or indicate cancellation status. These other options misinterpret the specific purpose and usage of the IIRN within the trademark registration framework.
