Trademark applications are filed at the Institute National de la Normalization et de la Propriété Industrielle (INNORPI). Multiple-class applications are possible, allowing applicants to cover multiple classes of goods or services in a single filing.

The key requirements include: A simply signed copy of POA (without legalization or notarization), which can be submitted within three months from the filing date. A general POA may be used for subsequent filings. A list of goods and/or services covered by the application in French. A certified copy of the priority document, home or foreign trademark registration/application (if claiming priority). The full name, nationality, and address of the applicant. A clear print of the mark (max 10 × 10 cm), if it is not a word mark. Failure to submit the required documents within the deadline may result in the trademark application lapsing.

Trademark applications are examined only on formal and absolute grounds to determine compliance with local rules regarding deceptiveness and distinctiveness. No search for prior third-party rights (such as similar or identical trademarks) is conducted during the examination.

If a national or international trademark (IR) designating Tunisia is refused, applicants can appeal before the First Instance Court within one month from the rejection notification receipt date. If the First Instance Court overrules the decision, further appeals can be made to the Appellate Court and Court of Cassation within 20 days respectively.

Before registration, a trademark application is published in the monthly Patent Office Gazette "Al-Muwassafat" for a 60-day opposition term. If no opposition is filed, the registration certificate is issued. If an opposition is filed, the applicant must submit a counterstatement within a non-extendable 60-day period. Failure to do so will result in the application being considered abandoned. If a counterstatement is filed, the Trademark Office reviews both statements and issues a decision, which can be appealed before the First Instance Court within one month, followed by further appeals to higher courts if necessary.
