1. How long did it take to enter the national stage? Give the applicant sufficient decision-making time, reduce risks and save costs. During this period, the applicant can make a preliminary assessment of the possibility of obtaining patent authorization for the patent application by using international retrieval and international preliminary examination procedures, and determine whether to apply in a specific country in combination with factors such as technological development and market prospects. Manpower, material resources and financial resources can be properly allocated. If you enter multiple countries at the same time, will the Paris Convention charge a large application fee for 12 months to enter multiple countries? However, there is enough time to raise funds through PCT.
It is very convenient to process a form in many countries. By submitting an international application, you can get an international application date that can take effect in many countries, and you can apply for a patent in many countries without submitting a patent application to each country separately, which provides convenience for patent applicants to apply for a patent abroad.
3. Providing reports before entering the national stage has great reference value, reducing risks and saving costs. An international patent application must be searched by an international search agency to obtain high quality before it can enter other countries. The international search report gives one or more existing technical documents, so that the patent applicant can not only know the status of the existing technology, but also preliminarily judge whether the invention has the prospect of granting a patent. If the international application passes the international preliminary examination, the patent applicant can also get a high-standard international preliminary examination report made by the international preliminary examination unit. If the international preliminary examination report shows that the invention does not have novelty, creativity and industrial practicability, the patent applicant may consider not entering the national phase again in order to save costs. If the patent application authorization conditions are insufficient, it will be rejected after entering multiple applicant countries, and the loss will be even greater.
The payment procedure is simple. You only need to pay the patent application fee to the acceptance bureau, not to the patent offices of all countries that require patent protection, which simplifies the payment procedures.
In some countries, the application fee is very low. In some countries, the cost of PCT national application is lower than that of ordinary application.
6. It is convenient and flexible to apply in your mother tongue. The application language can be Chinese, English, French, German, Japanese, Russian, Spanish, etc. China applicants can apply for international patents in both Chinese and English, which provides convenience for foreign-funded enterprises in China to find suitable registered trademarks as agents, which is far more convenient and faster than their own registration.
