What is Patent Cooperation Treaty?

The PCT is an international treaty with 153 Contracting States. This treaty helps the applicant in protecting their invention internationally when filing only one international patent application to be protected in a large number of countries instead of filing several separate national or regional patent applications. The granting of patents remains under the control of the national or regional patent offices in what is called the “national phase”.

The general procedures when filing an PCT application would be:

Filing, International search, International Publication, Supplementary International Search (optional), International Preliminary Examination (optional), National Phase.

With the filing step, the applicant needs to file an international application with a national or regional patent office or WIPO, complying with the PCT formality requirements, in one language, pay one set of fees. Before International Publication, the patent must go through an International Search by an “International Searching Authority” (ISA) (one of the world’s major patent offices). The purpose of this Search is to identify the published patent documents and technical literature which may have an influence on whether invention is patentable. After that, a written opinion on invention’s potential patentability will be issued. Then, the PCT application can go directly to national phase. However, there are two optional steps which applicants may go through: (i) Supplementary International Search (optional), and (ii) International Preliminary Examination (optional). These two steps based on applicant’s request should publish documents which may not have been found by the first ISA and carry out an additional patentability analysis, usually on an amended version of application, respectively.

How long does the PCT process take? Normally, applicant will have 30 months from the filing date of the initial patent application of which they claim priority or up to an additional 18 months from the time applicant files their international patent application before they have to begin the national phase procedures with individual patent offices and to fulfill the national requirements.

At any time, however, applicant may request an early entry into the national phase instead of waiting for the expiration of 30 months from the earliest filing date of their patent application. Once the application has gone into national phase, the time required for the examination and grant of a patent varies across patent offices of each state.

One of the important steps in filing PCT is to make sure the translation into Vietnamese language match up with the original language. Patent attorneys at ANT Lawyers will assist along the process including the translation of the patent and work with the national office of intellectual property in Vietnam to follow the instructions to complete the registration process in Vietnam.
