the convention on the unification of certain points of substantive law on patents for invention, also called strasbourg convention or strasbourg patent convention, is a multilateral treaty signed by member states of the council of europe on november 27, 1963 in strasbourg, france. it entered into force on august 1, 1980 and led to a significant harmonization of patent laws across european countries. this convention establishes patentability criteria, i.e. specifies on which grounds inventions can be rejected as not patentable. it intended to harmonize substantive patent law but not procedural law. this convention is quite different from the european patent convention (epc), which establishes an independent system for granting european patents. the strasbourg convention has had a significant impact on the epc, on national patent laws across europe, on the patent cooperation treaty (pct), on the patent law treaty (plt) and on the wto's trips. == ratifications and accessions == thirteen countries ratified the treaty or acceded to it: belgium, denmark, france, germany, ireland, italy, liechtenstein, luxembourg, the republic of macedonia, netherlands, sweden, switzerland, and united kingdom. == further reading == * christopher wadlow, strasbourg, the forgotten patent convention, and the origins of the european patents jurisdiction, iic, 2010, vol. 2, p.&nbsp;123ff. == see also == * agreement on trade-related aspects of intellectual property rights (trips) * community patent * international patent institute (iib) * european patent convention (epc) * paris convention * patent law treaty (plt) * substantive patent law treaty (splt) == external links == *official text of the convention *dates of signatures, ratifications, accessions and entry into force *declarations and reservations
