For family-sponsored immigrants, the priority date is the date that the Form I-130, Petition for Alien Relative, or in certain instances the Form I-360, Petition for Amerasian, Widow(er), or Special Immigrant, is properly filed with USCIS.
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.
Priority date refers to the earliest filing date in a family of patent applications. If the earliest-filed patent application for a particular invention was a provisional application, then the filing date of the provisional is your priority date.
119(c) extends the right of priority to “subsequent” foreign applications if one earlier filed had been withdrawn, abandoned, or otherwise disposed of, under certain conditions.
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.
Priority means that those who have submitted an application in one country are able to submit an application for the same invention in another country within twelve months and have the second application considered to have been submitted simultaneously with the first with regard to its novelty.
The priority date of a patent is the date on which you first file a patent application in respect of your invention. The application could be for a Dutch or a Belgian patent, or for a patent in any other country. You can make your invention public from this moment on as your idea has been registered as your invention.
The period of priority, i.e., the period during which the priority right exists, is usually 6 months for industrial designs and trademarks and 12 months for patents and utility models. The period of priority is often referred to as the priority year for patents and utility models.
A priority claim is a helpful, and often critical, way to link a later-filed patent application to an earlier-filed patent application. Known as a priority application, the earlier-filed application must generally have common subject matter and common inventorship in order for a priority claim to be made.
