Patent Application Processing Steps:
1. Overview of the Patent Application

When a national or resident of Trinidad and Tobago files a patent application the formal requirements under the Patent Rules and Regulations are:

1) The Patent Request Form No. 1.
2) A disclosure of the invention must accompany the application. This is the specifications of the invention, which include: Descriptions, Claims, Abstract & Drawings (If necessary).

This gives details about the invention such as the technical field to which the invention relates and also gives information relating to the background art which can be regarded as useful for understanding, searching and examining the patent applications. This is followed by the claims which define the invention in terms of the technical features of the invention. The abstract then follows and this is a summary of the disclosure contained in the description. Any drawings mentioned in the description are placed behind the abstract.

The application must be submitted in triplicate on A4 size paper as outlines in Rule 16 of the Patents Rules and Regulations together with the application fee of $2000. Once these formal requirements have been met, the person in the receiving office will stamp the application and a filing date will be issued, a file number will be issued and the processing of the application will begin.

2. How are payments made to the Intellectual Property Office?

Once an application is made, the prescribed application fee ($2000) must be paid. Maintenance fees (annuities) must be paid yearly from the filing date, commencing on the start of the second year.
All payments are due in advance, payable by certified cheque with the Payee as the Controller, Intellectual Property Office or by Linx or through the District Revenue Office, upon presentation of the prescribed voucher issued by the Intellectual Property Office.

This is the preliminary examination that begins at the time that a filing date is issued to the patent. Formal examination concerns the requirements that the applications must meet in order to proceed to substantive examination.
  • The tasks of the formalities examiner include ensuring that the application has been correctly made (reference to Form No. 1), checking such items as dates and inventors’ details, ensuring that the description and any drawings are correctly presented according to the rules so that they can be published, checking priority details, and so on.

  • Once the application complies with the Act and Rules the application will be granted.
