service, in particular as accessories or spare parts; provided he uses them in
accordance with honest practices in industrial or commercial matters.
Article 154
The registration of a mark shall not confer on its owner the right to prevent its usage
for products that have been introduced into the commerce of any country by the
owner or another person authorized by the right holder or with economic ties to the
patent owner. For these purposes, two persons shall be considered to have
economic ties when one of the persons is able to exercise a decisive influence on the
other, either directly or indirectly, with respect to the working of the patent or when a
third party is able to exert that influence over both persons.
The previous paragraph shall not apply where there exist legitimate reasons for the
owner to oppose further commercialization of the goods, especially where the
condition of the goods is changed or impaired after they have been put on the
market.
