What is one requirement to enter National Phase?

To enter the National Phase in the context of the Patent Cooperation Treaty (PCT), one key requirement is the payment of national fees. Upon the expiration of the international phase, which typically lasts for 30 or 31 months from the priority date (depending on the jurisdiction), applicants must file the necessary documents within the specified deadline to initiate processing in individual countries or regions where they seek patent protection.

The payment of national fees is critical because it not only facilitates the examination process but also demonstrates the applicant’s commitment to pursuing patent rights in that jurisdiction. Each country has its own fee structure, and failing to pay these fees could result in the application being deemed abandoned or rejected.

Other requirements may include fulfilling certain formalities such as providing translations of the application if necessary, but paying the national fees is a fundamental step that is universally required across the various patent offices.
