The unitary patent for Switzerland and Liechtenstein is a patent having a unitary character over the territories of Switzerland and Liechtenstein. It can either be a national patent, or a European patent granted under the European Patent Convention (EPC) and having a unitary character pursuant to Article 142(1) EPC.[3] The unitary patent "may only be granted, transferred, annulled or lapse in respect of the whole territory of protection," i.e. for both Switzerland and Liechtenstein.[4]

The special agreement establishing this unitary patent is the Treaty between the Swiss Confederation and the Principality of Liechtenstein on Patent Protection of 22 December 1978, which entered into force on 1 April 1980. This special agreement is also a regional patent agreement within the meaning of Article 45 PCT.[5] Amongst the bilateral treaties concluded between Switzerland and Liechtenstein in the field of patents, the Patent Treaty of 22 December 1978 is considered to be the most important one.[6]

A European patent may only be granted jointly in respect of Switzerland and Liechtenstein, following a joint designation under Article 149 EPC.[5][7] The unitary patent for Switzerland and Liechtenstein was the only unitary patent under Article 142(1) EPC in force until 2023,[8] when the unitary patent (applicable in 17 EU member states) regulation entered into force.

Dieser Ansatz würde den Art. 142–149 zu einer überraschenden Renaissance führen, deren Anwendungsfeld sich bisher allein im Patentschutzvertrag zwischen der Schweiz und dem Fürstentum Liechtenstein, (...), erschöpfte. [Translation: This approach [i.e., the future EU unitary patent] would lead Art. 142–149 to a surprising renaissance, as indeed the scope of application of these articles was until now limited only to the Patent Treaty between Switzerland and Liechtenstein (...)]
