An application for trademark registration can enjoy priority under the following circumstances:

1. Public display priority: If a trademark is publicly displayed in a certain country or region, and then it is applied for registration of the same trademark in other countries or regions within a certain period of time, it can enjoy public display priority. This means that subsequent applications can enjoy the same priority as the date of the first public display.

2. Priority international registration: According to the Madrid System, after one or more States parties to the Madrid Agreement have submitted their applications for international trademark registration, they can enjoy priority when applying for trademark registration in other States parties. This makes it possible for subsequent applications to apply in a simplified procedure within the period of enjoying priority.

3. Priority for domestic registration: In some countries or regions, an applicant for trademark registration can apply for the registration of the same trademark in other countries or regions within a certain period of time after applying for trademark registration for the first time in China and enjoy priority.

please note that the specific priority requirements and deadlines may be different due to the trademark laws and international agreements of countries or regions. When applying for trademark registration, it is recommended to refer to the requirements and guidelines of relevant trademark registration agencies or consult professional intellectual property lawyers to ensure the correct enjoyment of priority.
