As an alternative to using the standardized Request form PCT/RO/101, applicants may use WIPO’s ePCT system to generate a computer printout of the Request complying with the PCT Administrative Instructions. ePCT incorporates and expands the functionality of WIPO’s prior PCT-SAFE software. As of July 1, 2022, WIPO no longer develops, distributes, or supports PCT-SAFE. ePCT is a web-based application that does not require installation and subsequent periodic updates of any software on the user's computer. The ePCT system validates user-entered data and creates a zip file containing the Request and fee calculation sheet in PDF format. Submission of the ePCT zip file with an international application filed electronically (i.e., via the USPTO patent electronic filing system) entitles the applicant to a reduction of the international filing fee. For information on ePCT, see https://pct.wipo.int/ePCT.

The Request may not contain any matter that is not specified in PCT Rules 4.1 to 4.17 or permitted under PCT Rule 4.18(a) by the Administrative Instructions. Any additional material will be deleted ex officio. See PCT Rule 4.18(b) and Administrative Instructions Section 303.

Each date appearing in the international application or in any correspondence must be indicated by the Arabic number of the day, the name of the month and the Arabic number of the year, in that order. In the request, after, below or above that indication, the date should be repeated in parentheses with a two-digit Arabic numeral each for the number of the day and for the number of the month and followed by the number of the year in four digits, in that order and separated by periods, slashes or hyphens after the digit pairs of the day and of the month, for example, "20 March 2020 (20.03.2020)," "20 March 2020 (20/03/2020)," or "20 March 2020 (20-03-2020)."

(a) The filing of a request shall constitute:

• (i) the designation of all Contracting States that are bound by the Treaty on the international filing date;
• (ii) an indication that the international application is, in respect of each designated State to which Article 43 or 44 applies, for the grant of every kind of protection which is available by way of the designation of that State:

Pursuant to PCT Rule 4.9(b), certain States may be excepted from the all-inclusive designation system under limited circumstances. Specifically, where the international application contains a priority claim to an earlier national application having effect in a State whose national law provides that the designation of such State has the result that the earlier national application ceases to have effect in such State, then the request may contain an indication that such State is not designated. Applicability of PCT Rule 4.9(b) is contingent upon timely notice by the affected Office to the International Bureau. The Request may exclude the following designations: Germany (DE), Japan (JP), and Republic of Korea (KR).
