Trademark Priority: Determining Who Was First Trademark rights in the US generally belong to the one who was first to use the mark in commerce. Whoever was first to sell goods or services under a particular mark will typically be deemed the rightful trademark owner. This is known as trademark priority.
Priority dates of claims of a complete specification and the claim is fairly based on the matter disclosed in the specification referred to in clause (a) or clause (b), the priority date of that claim shall be the date of the filing of the relevant specification.
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.
To claim priority, you must file your international application within six months of filing your basic application.
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 It does not expire or change unless the application is abandoned or withdrawn.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.
Trade marks must be renewed every 10 years. You can renew a trade mark in the 6 months before it expires and up to 6 months afterwards. You cannot renew online if your trade mark expired more than 6 months ago.
The earliest filing date within a family of patent applications is referred to as the priority date. The priority date would be the filing date of the sole application when just one patent application is involved.
If a labor certification is required to be filed with your immigrant visa petition, the priority date is the date the labor certification application was accepted for processing by the Department of Labor.
