Frequently Asked Questions About the Patent Cooperation Treaty (PCT)

1) What is the Patent Cooperation Treaty (PCT)?

 

The PCT is an international treaty with more than 145 Contracting States. The PCT makes it possible to seek patent protection for an invention simultaneously in a large number of countries by filing a single “international” patent application 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 PCT procedure includes:

 

Filing: you file an international application with a national or regional patent Office or WIPO, complying with the PCT formality requirements, in one language, and you pay one set of fees.

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.

International Publication: as soon as possible after the expiration of 18 months from the earliest filing date, the content of your international application is disclosed to the world.

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.

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.

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 start 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.

Frequently Asked Questions About the Patent Cooperation Treaty (PCT)

 

2) How do I protect my invention in several countries?

 

Patents are territorially limited. In order to protect your invention in multiple countries you have a few options:

 

(a)  Direct or Paris route: you can directly file separate patent applications at the same time in all of the countries in which you would like to protect your invention (for some countries, regional patents may be available) or, having filed in a Paris Convention country (one of theMember States of the Paris Convention for the Protection of Industrial Property), then file separate patent applications in other Paris Convention countries within 12 months from the filing date of that first patent application, giving you the benefit in all those countries of claiming the filing date of the first application.

(b)  PCT route: you can file an application under the PCT, directly or within the 12-month period provided for by the Paris Convention from the filing date of a first application, which is valid in all Contracting States of the PCT and, therefore, simpler, easier and more cost-effective than both, direct or Paris route filings.

 

3) What are the advantages of the Patent Cooperation Treaty?

 

The PCT System has many advantages for you as an applicant, for the patent Offices and for the general public:

(a)  you have up to 18 months more than if you had not used the PCT to reflect on 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 your 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)  you have 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)  you 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)  you also achieve 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 your invention appears to be not patentable at the end of the international phase, you 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.

 

Ultimately, the PCT:

 

– brings the world within reach;
– streamlines the process of fulfilling diverse formality requirements;
– postpones the major costs associated with seeking multinational patent protection;
– provides a strong basis for patenting decisions; and
– is used by the world’s major corporations, research institutions and universities when they seek multinational patent protection.
