Editing Priority right (section)

==== Patent Cooperation Treaty ====

The Patent Cooperation Treaty, in its Article 8(1), provides the possibility of claiming a right of priority for the filing of an international application (PCT application):
{{cquote|The international application may contain a declaration, as prescribed in the Regulations, claiming the priority of one or more earlier applications filed in or for any country party to the Paris Convention for the Protection of Industrial Property.<ref name="8PCT"/>}}

{{PCT Rule|4|10|a}} goes on to mention that:
{{cquote|Any declaration referred to in Article 8(1) ("priority claim") may claim the priority of one or more earlier applications filed either in or for any country party to the Paris Convention for the Protection of Industrial Property or in or for any Member of the World Trade Organization that is not party to that Convention.<ref>{{PCT Rule|4}}</ref>}}

However, Rule 4.10(a) as amended with effect from January 1, 2000 does not apply to all designated Offices.<ref>[http://www.wipo.int/pct/en/texts/rules/r4.htm#note1 Rule 4, note 1, Patent Cooperation Treaty]</ref> For instance, for the [[European Patent Office]] as designated Office, the old Rule 4.10(a) still applied until December 12, 2007, that is, rights of priority of first applications made in a WTO member not party to the Paris Convention were not recognised. Now and more specifically for European patent applications filed on or after December 13, 2007 (the entry into force of the new version of the [[European Patent Convention]], the so-called [[EPC 2000]]), the rights of priority of first applications made in a WTO member are recognized under the European Patent Convention.<ref>{{EPC Article|87|1|b}}</ref><ref>[http://www.european-patent-office.org/epo/pubs/oj007/08_07/special_edition_4_epc_2000_synoptic.pdf Special edition of the Official Journal of the EPO 4/2007 - Revision of the European Patent Convention (EPC 2000).
