26 Article 74 A mark shall be registered in respect of one or more of the categories of goods produced, or intended to be produced, by the applicant in accordance with the rules and conditions prescribed by the Regulations. Its use shall be limited to the category, categories or the kinds of products for which it has been registered. Provisions of Article 91 shall apply to the categories for which the mark has not been seriously used. Article 75 Where an application for registration of a mark is filed in a country or an entity member in the World Trade Organisation, or a country which extends reciprocity to Egypt, the applicant, or his rightful successor, may, within six months from the date of filing the application, file with the Department in Egypt a similar application for the same mark, covering the same products included in the previous application, in accordance with the terms and conditions prescribed by this Law and its Regulations. In such a Case the priority date shall be that of the first application in the foreign country. Article 76 Where two or more persons apply simultaneously for registration of the same mark, or similar marks for the same category of products, registration shall be suspended until such time when one of these persons shall have produced a renunciation by the other claimants or until a binding judgement has been issued in his favour. Article 77 The Trade Registry Department may, in a motivated decision, require the applicant to undertake the necessary modifications on the subject mark in order to define and clarify the mark so as to avoid its confusion with a mark already registered, or a mark for which a registration application has already been filed. Such decision shall, within 30 days of its issue, be communicated to the applicant in writing, by registered mail with acknowledgement of receipt. The Department may reject the application should the applicant fail, within six months of the notification, to introduce the amendments required.
