Patent’s Cooperation Treaty (PCT). Article 19 pct, and the possibility to modify the claims before the publication of the international application.

When we file a patent application through the PCT system, the first thing we would like to obtain from the Office responsible for the search is the International Search Report (ISR), which informs us of the inventive level of our invention.PCT patent

From there, we will be able to modify amend as far as possible our application in order to adapt it to the patentability requirements solicited, allowing us to obtain a strong application able to provide us the extent in the countries of interest.

On receiving the ISR, most professionals directly goes to the results of the examiner, without paying much attention to the rest of the documents attaches by the International Patent Office, specifically I mean the following document:

Modificación de las reivindicaciones por el PCT

This document informs us of the various options available for us after receiving the ISR, among which there is the realization of modifications of the claims under PCT article 19, regardless of a subsequent request or not of the Preliminary International Examination (IPER). Besides, these changes will be included in the publication of the application.

It should be taken in mind that under PCT article 19 it is possible only to modify the claims of the application. So, if we want to modify any other part of the text we should wait until IPER application and make them under PCT article 34.

Modification of claims before publication by the pct: requirements

The International Patent Office also informs us of the requirements in order to apply for the modifications of PCT article 19. These requirements are:

1        The application must be filed directly before the International Bureau (IB) within one of the following period which expires later:

  • 2 months from the date of issue of the International Search Report and written opinion.
  • 16 months from the date of priority.

However, if the application is filed after these deadlines, the International Bureau will continue to consider it as submitted on time, if and when all the preparations for the publication of international application has not been completed.

2        A new set of claims should be provided in order to replace the previous ones, in which will be included the modifications made along with an explanatory letter that:

  • Will identify the claims that, due to modifications, shall be different from the originally filed, and call the attention on the differences between the claims originally filed and the modified ones.
  • Will identify the assertions originally filed that has been cancelled as a consequence of modifications.
  • Will identify the reasons of the modifications in the application as it was filed.

3        The language of the new set of claims shall be the same as the one of the original application, considering that it is going to be published with that.

4        The modifications realized cannot represent a substantial change on the content of the original patent application.

In conclusion, simply note that since all the modifications to the claims under article 19 are published within the PCT international application, these amendments may be useful to the applicant, if there is a reason to better define the scope of the claims towards the provisional protection of designated states whose national law includes such protection.
