Definition Edit

U.S. patent law Edit

The priority date is the initial date of filing of a patent application, normally in the applicant's domestic patent office. This date is used to help determine the novelty of an invention. This date is also used to determine the application date of foreign-filed applications, when done in a Convention country.[1]
