The country deposited its instrument of accession to the PCT on 9 March. Residents of Jordan will be entitled to file international applications from 9 June.
The PCT launched in 1978 with 18 contracting states. Last month, the World Intellectual Property Organization published its three millionth international patent application under the treaty.
WIPO director general Francis Gurry said the PCT has become the “central pillar of the international patent system, the primary vehicle for applicants seeking patent protection internationally”.
“It is one of WIPO’s key assets, accounting for 76 percent of its revenue and enabling the financing and development cooperation programme of the organisation and of many of its other programmes, and there is every expectation that its growth and vitality will continue.”
