A PCT application can claim priority to an earlier application, and multiple applications can claim priority to the first application within the 12-month priority period. A priority claim is only valid for subject-matter (e.g. features of the invention) that were disclosed, for the first time, in the first application.
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.
What is claiming priority? Claiming priority back-dates your protection, whether you have a registered design, a patent or a trade mark. Claiming priority from your first application for something means you don't have to file for protection in multiple places at the outset, with all the fees that would entail.
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.
