The priority date for a trademark is established when the application is filed and remains fixed. It does not expire or change unless the application is abandoned or withdrawn. The priority date serves as a permanent reference point for determining the order of rights and protecting the trademark.

A trademark priority date is the earliest a trademark can be registered with the US Trademark Office (USPTO). This date is usually the date of first use or first filing. A trademark registration date is an actual day on which the mark is officially registered with the USPTO.
