International Patent Filing via Patent Co-operation Treaty (PCT)

Why to file International Patent Application?

For protecting an invention, patent protection is taken by people, multi-national companies, research institutions and universities. Since, patent protection is jurisdiction specific in nature, it only gives the protection for the country in which it is filed. An international patent application helps applicant to seek patent protection based on the priority date of initial application in other countries also. Therefore, there is a need of an international patent protection.  There are broadly two ways for seeking international patent protection: Convention Patent Application and PCT Application.

What is a PCT Application?

The Patent Cooperation Treaty, or the PCT as it is typically referred to, came into existence in 1970. The Treaty, which like any other Treaty is a legal agreement entered into between various countries.  The purpose of the PCT is to streamline the initial filing process, making it easier and initially cheaper to file a patent application in a large number of countries.You accomplish this by filing an “international patent application.” [1]

It may generally be filed with the national patent office of the Contracting State of which the applicant is a national or resident or, at the applicant’s option, with the International Bureau of WIPO in Geneva.If the applicant is a national or resident of a Contracting State party to the European Patent Convention, the Harare Protocol on Patents and Industrial Designs (Harare Protocol), the Bangui Agreement, or the Eurasian Patent Convention, the international application may also be filed with the European Patent Office (EPO), the African Regional Intellectual Property Organization (ARIPO), the African Intellectual Property Organization (OAPI) or the Eurasian Patent Office (EAPO), respectively.

Filing a PCT application has the effect of automatically designating all Contracting States bound by the PCT on the international filing date. The effect of the international application is the same in each designated State as if a national patent application had been filed with the national patent office of that State.[2]

Procedure to file PCT application 

PCT being an international regime to protect inventions by granting patents, it has some rules and procedure of its own for doing so. Among them some are mandatory (such as filing of the application, international search, international publication and national phase) and some are optional (such as supplementary international search and international preliminary examination). When the applicant files the PCT application at the regional patent office or directly at international authority, the application is examined by the ISA (International Search Authority) whether its patentable or not and published in international journals so that whole world will know about the invention and oppositions can be filed from all over world.

Though the examination and publication all are done by international authority but the granting of patents remains under the control of the national or regional patent Offices in what is called the “national phase”. So, the filing procedure is,

Filing: An international application is filed with a national or regional patent Office or WIPO, complying with the PCT formality requirements, in one language, and a set of fees. This has to be done with in 12 months of filing the local application.

International Search: An “International Searching Authority” (ISA) (one of the world’s major patent Offices) identifies the published patent documents and technical literature (“prior art”) which may have an influence on whether your invention is patentable, and establishes a written opinion on your invention’s potential patentability. This has to be published with in 16 months from the filing the application at home country.

International Publication: As soon as possible after the expiration of 18 months from the earliest filing date, the international application comes into public domain. This has to be published within 18 months from the filing the application at home country.

Supplementary International Search (optional): A second ISA identifies, at your request, published documents which may not have been found by the first ISA which carried out the main search because of the diversity of prior art in different languages and different technical fields. This has to be published within 22 months from the filing the application at home country.

International Preliminary Examination (optional): One of the ISAs at your request, carries out an additional patentability analysis, usually on an amended version of your application. This has to be published within 28 months from the filing the application at home country.

National Phase: After the end of the PCT procedure, usually at 30 months from the earliest filing date of your initial application, from which you claim priority, you to pursue the grant of your patents directly before the national (or regional) patent Offices of the countries in which you want to obtain them.

What are the costs associated with a PCT Application?

PCT applicants generally pay three types of fees when they file their international applications:

(a) an international filing fee,

(b) a search fee which can vary depending on the ISA chosen, and

(c) a small transmittal fee which varies depending on the receiving Office.[3]

Cost of filing a PCT  Application in India

In India the filing cost of PCT will be,

  1. Transmittal fee of e-filing- Natural Person- 3200 INR, Small Entity – 8000 INR, Others – 16000 INR and for physical filing – Natural Person- 3250 INR, Small Entity – 8800 INR, Others – 17600 INR
  2. International filing fee for Indian Applicant – 1471 USD (Fee per sheet over 30 is 17 USD and reduction in fee for PCT easy filing 11 USD)
  3. Search fee for Indian applicant choosing Indian Patent office as ISA, for individuals 2500 INR and others 10,000 INR.
  4. Preliminary Examination fee where the ISR was issued by ISA/IN for individuals is 2500 INR and others 10,000 INR and where the ISR was not issued by ISA/IN for individuals is 3000 INR and others 12,000 INR.[4]

What is a Convention Application?

The Paris Convention is an international treaty that allows applicants to file a first application in their home country. That application is referred to as a priority document or filing, and the date it is filed is called the priority date.

The priority filing starts a 12-month period within which a further application called a Paris Convention application (or a direct application claiming priority) can be filed elsewhere, claiming Paris Convention priority back to the priority date. To the extent that the content of the Paris Convention application is disclosed in the earlier priority document, it will be backdated to the priority date.

The 12-month convention period lets the applicant seek funding, perform market research and turn an idea into a commercial product. All of these can be done following a single filing without risking a loss of rights in other countries.

If the Paris Convention didn’t exist, applicants would need to coordinate simultaneous filing in all countries that are of potential interest at the very start of the process. This would be complicated and costly, bearing in mind the need for translations in many countries.[5]

Comparison of PCT Application Vs Convention Application

(a)  For entering in National Phase Filing, a Convention Application allows only 12 months from the priority date while a PCT Application provides around 30/31 months. This additional helps in determining the desirability of seeking protection in foreign countries, to appoint local patent agents in each foreign country, to prepare the necessary translations and to pay the national fees;

(b)  If an international application is in the form prescribed by the PCT, it cannot be rejected on formal grounds by any PCT Contracting State patent Office during the national phase of the processing of the application;

(c)  The international search report and written opinion contain important information about the potential patentability of your invention, providing a strong basis for you to make business decisions about how to proceed;

(d)  An applicant has the possibility during the optional international preliminary examination to amend the international application, enter into dialogue with the examiner to fully argue your case and put the application in order before processing by the various national patent Offices;

(e)  The search and examination work of patent Offices in the national phase can be considerably reduced thanks to the international search report, the written opinion and, where applicable, the international preliminary report on patentability that accompany the international application;

(f)  An applicant may be able to fast-track examination procedures in the national phase in Contracting States that have PCT-Patent Prosecution Highway (PCT-PPH) agreements or similar arrangements;

(g)  Since each international application is published together with an international search report, third parties are in a better position to evaluate the potential patentability of the claimed invention;

(h)  For you as an applicant, international publication online puts the world on notice of your invention. You may also highlight your interest in concluding licensing agreements on PATENTSCOPE, which can be an effective means of advertising and looking for potential licensees;

(i)  An applicant also achieves other savings in document preparation, communication and translations because the work done during the international processing is generally not repeated before each Office (for example, you submit only one copy of the priority document instead of having to submit several copies); and

(j)  If an invention appears to be not patentable at the end of the international phase, applicant may abandon the PCT application and you will have saved the costs you would otherwise have incurred by directly seeking protection in foreign countries, appointing local patent agents in each foreign country, preparing the necessary translations and paying the national fees.[6]

 

Conclusion

 

This is a statistical data taken shows the highest 10 PCT filing countries for the year of 2016-17 (updated on November,2018). From this we can see that, globally entities are interested not only protecting their inventions in their home country but also in a global level. So, for that PCT is the easiest, cost and effective way to get it protected. In the above statistics it can be concluded that from 2016 to 2017 except for Netherlands and France in other 8 countries have seen growth in the number of applications. In China, Japan and Sweden the growth percentages are 13.5%, 6.6% and 6.9% respectively which are more than other countries.[7]

If we see the above chart we can see that the number of filings in India under PCT has been increasing gradually through all this years. This shows that Indian inventors are also not only concerned about protecting their inventions in India, but also on global level and the reason being same easiest, and cost effective mechanism to get the maximum protection available for their invention.

After viewing the above two statistical data it clear that people want their invention patented in countries possible including their home country and as patent are given over new inventions which have extensive industrial use and high economic values such as life saving pharmaceutical products. So, it should be protected from being infringed by any means. But the problem is that the applications are only examined and published by the International authorities and the protection is given by the Patent offices of dedicated countries through their domestic laws which vary from country to country and there is uniformity. So, besides examination and publication the International Authority should have power to also grant patent for a specific period.

So, for this this is how PCT brings the world within reach and streamlines the process of fulfilling diverse formality requirements and it also postpones the major costs associated with seeking multinational patent protection provides a strong basis for patenting decisions.
