The claim or right of priority (also called the Convention priority) is a part of the Paris Convention binding member nations of its Paris Union to a common agreement over the handling of international trademarks. This claim guarantees that if you file an application to Trademark Offices in a member nation within six months of a first filing, the date of recorded will be the same day as the initial application. The applicant thus has a priority claim to the timely follow-up registration of their mark across any country in the Union.
