Subsection V Joint ownership of patents 77. Subject to Article 80 below, the joint ownership of a patent application or a patent shall be governed by the following provisions: (a) Each of the joint owners may work the invention for his benefit, provided that he fairly compensates the other owners who are not personally working the invention or who have not granted licenses for use. Failing amicable agreement, such compensation shall be fixed by the court; (b) Each of the joint owners may take legal proceedings in respect of infringements for his sole benefit. The petition for infringement must be notified to the other joint owners. No court decision shall be taken on the proceedings until proof of such notice has been provided; (c) Each of the joint owners may grant a third party a non-exclusive license for use for his benefit, provided that he fairly compensates the other joint owners who are not personally working the invention or who have not granted licenses for use.

The parties shall have 30 days as from notice of the court decision, to withdraw from the grant or the purchase of the joint owner’s share, without prejudice to the award of any damages which may be due; costs shall be borne by the withdrawing party. (d) An exclusive license for use may only be granted with the consent of all of the joint owners or by leave of the court; (e) Each joint owner may assign his share at any time. The joint owners shall have a right of preemption for three months starting with the notice of intent to assign. Failing an agreement on the price, it shall be fixed by the court. The parties shall have 30 days as from notice of the court decision to withdraw from the sale or purchase of the share of the joint ownership, without prejudice to the award of any damages which may be due; costs shall be borne by the withdrawing party. 78.
