An Australian provisional patent application lodged at IP Australia (IPA) is usually the first step in obtaining one or more patents anywhere in the world. The date on which a provisional patent application is received by the IPA is known as its “priority date”. To obtain patent protection in specific countries of interest, it is necessary to establish a filing date in the countries of interest within 12 months of filing the provisional patent application, in order to maintain the priority date. There are two ways to establish this filing date:
1. By filing individual complete patent applications directly in the countries of interest.
2. By filing a Patent Cooperation Treaty (PCT) International Patent Application, followed by filing individual complete patent applications in the countries of interest within 18 months of the date the PCT International Patent Application is filed.
In relation to option 1, if an inventor intends on filing several individual patent applications directly, filing costs will be significant. One advantage of electing to proceed with option 2 is that the deadline for filing individual complete patent applications in the countries of interest is delayed by up to a further 18 months (i.e. 30 months from the priority date). Consequently, the significant costs associated with these individual applications are also delayed.
