29 Article 89 The transfer of ownership, the right of disposal or the mortgage of a mark shall not be valid towards a third party, unless such has been duly recorded in the register and published in the Official Gazette in the manner prescribed in the Regulations. Article 90 The period of protection conferred by the registration of the mark is 10 years, renewable for an identical period or periods upon request of its owner and every time within the last year of the protection period, against payment of the fees due for the initial registration application. The owner of the mark may request the renewal of the protection period within six months after the date of its expiry against payment of the prescribed fees and a supplement prescribed by the Regulations not exceeding 500 pounds, failing which the Department shall proceed to cancel the said mark from the register. Article 91 The competent court may, upon request by any interested party, issue an enforceable decision to cancel the registration if it appears to the court that the mark has not been seriously used for a period of five consecutive years. Article 92 A cancelled mark may be re-registered - in favour of its owner exclusively - within three years from the date of the cancellation, according to the prescribed conditions and same procedure of registration and against payment of a fee prescribed by the Regulations not exceeding 1,000 pounds. After the lapse of the said period, a mark may be re-registered for the benefit of its owner or a third party, in connection with the same products, under the same conditions, procedures and fees of the initial application for registration. However, where the cancellation is in response to an enforceable court order invalidating the registration of a mark, such a mark may be registered in favour of a third party soon after the cancellation. Article 93 Extension, renewal, cancellation or reinstatement of the registration shall be published in the Trademark and Industrial Designs Gazette in the manner prescribed by the Regulations. Article 94 The Department, or any interested party, may, in cases other than provided for in Article 85, submit to the competent court a request for the addition of any entry which would have been omitted, or to delete or modify any entry incorrectly inscribed therein or contrary to the truth.
