A PCT application is a patent application for a maximum of more than 140 countries simultaneously. PCT stands for Patent Cooperation Treaty. In contrast to a national or European patent application, a patent cannot be granted via this route. An international organization (World Intellectual Property Organization, or WIPO) carries out a novelty search and, if desired, a preliminary substantive assessment. The applicant - and usually his/her patent attorney - can file corrected documents during the international procedure. After 30 months (or even later in some countries/regions) the international patent application can be continued as national or regional patent application.
