1. Extension of European patent possible. 2. May only be designated for a regional patent (the "national route" via the PCT has been closed).
Where a State can be designated for a regional patent, the two-letter code for the regional patent concerned is indicated in parentheses (AP = ARIPO patent, EA = Eurasian patent, EP = European patent, OA = OAPI patent).
Important:
This list includes all States that have adhered to the PCT by the date shown in the heading. Any State indicated in bold italics has adhered to the PCT but will only become bound by the PCT on the date shown in parentheses; it will not be considered to have been designated in international applications filed before that date.
Note that even though the filing of a request constitutes under PCT Rule 4.9(a) the designation of all Contracting States bound by the PCT on the international filing date, for the grant of every kind of protection available and, where applicable, for the grant of both regional and national patents, applicants should always use the latest versions of the the request form (PCT/RO/101) and demand form (PCT/IPEA/401) (the latest versions are dated April 2007) or, if filing the request using the PCT-EASY features of the PCT-SAFE software, the latest version of that software (which is available at www.wipo.int/pct-safe). The request and demand forms can be printed from the PCT website, in editable PDF format, at: www.wipo.int/pct/en/forms/, or obtained from receiving Offices or the International Bureau, or, in the case of the demand form, also from International Preliminary Examining Authorities.
