* Austria and Luxembourg both signed the 1960 Paris Convention, the 1964 Additional Protocol to amend the Paris Convention and the 1982 Protocol to amend the Paris Convention. Neither country has ratified any of these instruments.
** On 9 March 2009, Switzerland deposited its instrument of ratification of the 1960 Paris Convention as amended by the 1964, 1982 and 2004 amending Protocols; however, this ratification was effective only with respect to the 1960 Paris Convention as amended by all three Protocols. Therefore, entry into force for Switzerland of the Paris Convention as so amended only took place once the 2004 Protocol to amend the Paris Convention itself entered into force, i.e. on 1 January 2022.
*** On 17 December 2021, Belgium, Denmark, Finland, France, Germany, Greece, Italy, the Netherlands, Portugal, Slovenia, Spain, Sweden and the United Kingdom deposited their instruments of ratification, acceptance or approval in accordance with Article 20 of the Paris Convention and requested that the deposit be registered on 1 January 2022.
