If the deposit of a layout-design of integrated circuits has been made on behalf of several persons, it may be withdrawn only if so required by all the persons concerned. If rights, in particular a pledge or a license, have been entered in the National Register of Layout-designs of Integrated Circuits, the declaration of withdrawal shall be admissible only if it is accompanied by the written consent of the owners of these rights. 16. The deposit of a layout-design of integrated circuits shall be declared void by means of a court decision in the following cases: — if the layout-design of the integrated circuits, as defined in Article 3 of this Law, may not be protected; — if the depositor does not have the status of creator, as defined in Article 5 of this Law; — if the deposit has not been made within the period specified in Article 11 of this Law.

The decision to declare void shall have absolute effect. Chapter III Rights Attached to the Deposit 17. Without the authorization of the owner, third parties shall be forbidden to: — reproduce all or part of the layout-design of integrated circuits, apart from where the reproduction is of a part which does not satisfy the requirements of originality; — use, for commercial purposes, a reproduction of the layout-design of integrated circuits or import for this purpose such a reproduction or any product incorporating it; This prohibition shall not extend to: — reproduction for evaluation, analysis, research or teaching purposes; — creation, from such analysis, research or evaluation, of a distinct layout-design of integrated circuits able to claim the protection provided for by this Law. The prohibition provided for in the first subparagraph of this article may not be effective against any person who acquires an integrated circuit in good faith. That person shall, however, be liable to pay fair compensation if he intends to continue the commercial use of the circuit. Where an amicable settlement is not reached, the amount of this compensation shall be fixed by the competent court. 18.
