Priority dates
Up one level
The priority date of a patent application is the date the patent application is first filed. This can be the filing date of a convention application in another country or the filing date of a provisional specification in New Zealand or the filing date of a complete specification in New Zealand if no provisional specification has been filed. The date of filing is the date the patent application is filed in New Zealand. To contest the priority date of the patent application you must provide evidence to show that the priority date of the patent application is not valid.
