International Patent Cooperation Treaty

Many of the most significant patenting regions (e.g. Japan, the USA and Europe) are also signatories of the International Patent Cooperation Treaty (PCT). This allows for an initial review of the patent application to be undertaken by a single patent office. The office then provides a summary assessment of this application, which provides an indication of the likely response that would be obtained from individual PCT countries. For many, this initial assessment plays a major role in deciding whether to proceed with the patent application in individual countries. 

The prosecution procedure of official action and responses may be repeated in all of the individual countries where a patent application was filed. Fortunately, international patent cooperation treaties exist to shorten and simplify this awkward process for both sides. 

The International Patent Cooperation Treaty (PCT) created the opportunity to file a patent application almost world-wide (most countries accept PCT applications) at international patent registration offices which are usually identical with the national patent offices. A search report summarizing relevant prior art will be issued and, if requested, a preliminary examination considering the prior art is performed. The preliminary international examination provides a non-binding opinion whether the claimed invention appears to be novel, inventive and industrially applicable. It does not investigate the patentability according to any national law. 

Anyone applying for a patent at the national or international level is required to determine whether their creation is new or is already owned or claimed. To determine this, huge amounts of information must be searched. The U.S. Patent and Trademark Office (USPTO) and the World Intellectual Property Organization s (WIPO) International Patent Cooperation Treaty (PCT) have created classification systems which organize information concerning inventions into indexed, manageable categories for easy retrieval.

One important tool in the international patent world is the Patent Cooperation Treaty (PCT). By filing an international patent application, one may seek patent protection for an invention simultaneously in each of a large number of countries. Such an application may be filed by anyone who is a national or resident of a contracting state of the PCT. A list of the more than 120 contracting states can be found on the website of the World Intellectual Property Organization (WIPO) [5]. The effect of the international application in each such state is the same as if a...

After submission to a patent office, the file is examined for some basic formal requirements and, if adequate, is given a filing date. A first indication about the chances of a patent application may be obtained from a search report which is issued by the European Patent Office and also for international patent applications under the Patent Cooperation Treaty (see below). In most cases, the search report will list a number of earlier patents or publications and indicate whether these interfere with the proposed claims of the examined file. As a consequence of the search report the applicant can amend the proposed claims before the examination is initiated. 

Apart from applications to national authorities, patent applications may also be made through the European Patent Office (EPO) and the International Bureau of the World Intellectual Property Organisation (WIPO) under the Patent Cooperation Treaty (PCT). 

Articles 31 to 42 PCT provide for an international preliminary examination to be performed during the international phase (Chapter II of the Patent Cooperation Treaty). Countries having acceded to the Patent Cooperation Treaty can make a declaration that they will not be bound by Chapter 11 of the Patent Cooperation Treaty. An applicant resident in a country which is bound by Chapter II of the Patent Cooperation Treaty can make a request for an international preliminary examination to be performed for selected patent offices, known as elected offices . After the issue of the search report (and the international preliminary examination, if applicable and requested) the application passes to the national patent office of each of the designated countries and this is the start of the national phase of the procedure. On request of the applicant, a substantive examination takes place in each of the designated countries, (and the EPO, if designated), under the laws of that country. 

Patents are usually filed first in the inventor s or assignee s home country. US companies, for example, need to get permission from the US PTO in order to do a foreign filing first. It used to be that US patent applications weren t published at all, but that international (PCT, Patent Cooperation Treaty) applications were published 18 months after filing. But in late 2000 the US followed suit, so that now US patent applications appear a year-and-a-half post filing as well, unless the owner of the patent either requests earlier publication (quite unlikely), or requests that it not be published at all and then certifies that a patent won t be sought for the invention in other countries where applications are published. Most of the time, then, applications will appear, and be accessible on the web as described later, at the 18-month timepoint, whether US or not.

The Patent Cooperation Treaty (PCT) is an international agreement that extends the time before formally moving forward on fifing the patent by another 18 months. Individuals may request this to gain another 18 months to further refine the final product and decide if the idea merits investment of the final costs of patenting.
