This search is crucial to determine the existence of potentially confusing or similar trademarks on the register. By conducting a thorough trademark search, you can proactively identify and avoid potential objections or oppositions based on pre-existing marks, safeguarding the smooth registration of your trademark.

Please note, we cannot change the mark that you register for, or the goods listed in your application once you file. For this reason, the goods listed in your application must be an accurate description of your actual products.


After an application is filed, it is examined by the Trademark Registry, Colomobo so as to ascertain its registrability and/ or any similarity with exisisting marks. If an objection to a registration is raised, an official examination report will be issued by the Trademarks Registry.

The Registrar may accept or refuse the application subject to the provisions of the ordinance. A trademark application in Sri Lanka can be refused/ objected by the Registrar on the following grounds:

- A mark is similar/ identical to an earlier trademark for the same or similar goods/ services.
- A mark is similar/ identical to an earlier trademark in respect of different goods/ services.

The above categories of marks may however be registered if the proprietor of the earlier trademark consents or there has been an honest concurrent use of the later mark.

Further the objections raised by the Registrar with regard to an application, is forwarded to the applicant and the applicant has to file an appropriate reply with the supporting documents to the official objections within 30 days. The Registrar may accept the application on the basis of the reply and documents filed or may list the application for hearing.


After examination and upon acceptance of the response by the Registrar, the application is ordered for advertisement/ publication in the Trademarks Journal. An application is advertised in the Trademarks Journal for a period of 3 months from the date of publication, so as to invite the public for filing opposition against the registration of the mark.


When a trademark is published in the Trademark Journal, any individual has the opportunity to oppose its registration. This is done by submitting a notice of opposition within a specified period of 3 months from the date of publication in the Journal.

Grounds for Opposition:

Opposition to a trademark application in Sri Lanka can be based on grounds outlined in Section 103 and 104 of the Intellectual Property Act no. 36 of 2003. Section 103 identifies reasons for a mark to be ineligible for registration, while Section 104 deals with marks that may be excluded due to third-party rights.

Response by Applicant:

Once an opposition is lodged, the trademark registry serves a copy of the notice of opposition to the applicant. The applicant is then required to provide their response to the grounds of opposition within three months. Failure to do so may result in the application being deemed abandoned.

Request for Evidence:

Subsequently, the Registrar may request written evidence from both the opposing party and the applicant.


If the dispute remains unresolved, a hearing is scheduled to address the matter.

Registrar's Decision:

Following the hearing, the Registrar will make a determination on whether the trademark should be registered or not.

Appeal Process:

If the Registrar decides to register the trademark, there is a specific period within which an appeal can be lodged against this decision. After the appeal is resolved, the Registrar will take appropriate action accordingly.


The application shall proceed to registration where there is no opposition or where the opposition was filed and was decided in favour of the applicant. The mark is then registered for a period of 10 years from the date of filing of the application and the registration certificate is issued.
