International Trademark Search by Date of Priority: A Comprehensive Guide
What is International Trademark Search by Date of Priority?
An international trademark search by date of priority involves searching for existing trademarks in multiple countries to ensure that your brand does not infringe on any existing rights. This search is based on the date of priority, which is the date on which the first trademark application was filed. The priority date is essential in determining the validity and scope of trademark rights.
The Paris Convention and Priority Dates
The Paris Convention for the Protection of Industrial Property is an international treaty that establishes a framework for the protection of industrial property rights, including trademarks. Article 4 of the Convention allows for the claiming of priority for trademark applications filed in member countries. This means that if you file a trademark application in one country and later file an application in another country within six months, you can claim the original filing date as your priority date.
Types of Priority Rights and Their Effects on Trademark Registration

- Actual Use in Commerce:** Actual use in commerce determines the rights to a trademark. If you have not used your trademark in commerce, you may not have the right to claim priority.
- Filing Application Date:** The filing application date is used to establish the priority date for trademark registration.
- Intent-to-Use Application:** An intent-to-use application allows you to claim priority based on a foreign filing date, provided you file the application within six months.
How to Claim Priority for Trademark Applications
To claim priority for a trademark application, you must file a subsequent application in a member country within six months of the original filing date. This allows you to benefit from the earlier filing date and potentially strengthen your trademark claim.
Best Practices for Securing and Leveraging Priority Dates
- Conduct a Comprehensive International Trademark Search:** Thoroughly search for existing trademarks in multiple countries to ensure that your brand does not infringe on any existing rights.
- File a Single International Trademark Application:** File a single international trademark application under the Madrid System to apply for protection in up to 132 countries.
- Claim Priority in a Timely Manner:** Claim priority for your trademark application within six months of the original filing date to benefit from the earlier filing date.
- Monitor and Maintain Your International Trademark Registration:** Regularly monitor and maintain your international trademark registration to ensure that your rights are protected.
