PCT National Phase
In most cases, a year is not enough time to gather investors, to test the recently developed invention your company is launching and to know exactly in which countries the invention will have commercial applicability. With a PCT Application you do not need to decide where to file specific foreign patent applications for up to 30 months from your first priority date. Even more, the PCT is a standardized process to file multiple applications in foreign countries.
If you already have an International PCT and need to enter into National Phase in China, we only required the following:
PCT publication number International Search Report Patent specifications in local language. Any amendments made to the PCT original filing, if applies. Local Filing
If you have filed a patent in any country and you need to expand its protection to China, you can proceed with a national application within 12 months from the earliest priority filing date. In general, a direct national patent application strategy is recommended if you know exactly where your target market is and probably if you want to protect your application in a few countries only.
If you need to proceed with the filing of a national application you have to consider the following requirements:
Patent specifications in local language (Abstract, application text, claims and drawings). Copy of the foreign priority including, country, filing date, title, owner and inventors. If applies.
