The co-owner of a patent application or patent may notify the other co-owners that he is surrendering his share to them. With effect from the entry of such abandonment in the National Patent Register or, in the case of a patent application which has not yet been published, with effect from its notification to the National Institute of Industrial Property, the said co-owner shall be discharged from all obligations towards the other co-owners; the latter shall share the abandoned share in proportion to their rights in the co-ownership, unless otherwise agreed.
