Postal Filing

The international application can be filed directly with the RO (A10 PCT and Guide for Applicants §6.003).

The terms of direct filing (addresses, etc.) are governed by the applicable national law.

Filing by Mail

The international application can be mailed to the RO (Guide for Applicants §6.003).

The terms of direct filing (addresses, etc.) are governed by the applicable national law.

Filing by Fax

Principle

The international application can be sent by fax to the RO (Guide for Applicants §6.003) if:

The use of fax is governed by Rule 92.4 PCT (or other similar means resulting in a printed or written document).

If the fax is unreadable (in whole or in part), the fax is considered as not having been received and the applicant is informed (R92.4.c PCT).

Case of the EPO

Before the EPO, it is still necessary to submit in one copy (A151 EPC together with R157(2) EPC) the paper copy of the application documents as well as the request.

It is advisable to indicate on the fax that paper documents are being sent at the same time by mail (“Decision of the President of the European Patent Office, dated February 20, 2019, concerning the filing of patent applications and other documents by fax”, OJ 2019, A18).

If no documents are received, the EPO invites the applicant to submit these documents within 2 months (and not 14 days as indicated above).

If the applicant does not respond to this invitation, the fax is deemed not received, meaning that the application is deemed withdrawn (R92.4.g.i PCT).

Electronic Filing

PCT-Easy

The filing can be done using PCT-EASY: a paper filing accompanied by an electronic version (floppy disk, CD-ROM).

The PCT-EASY software can be used (R89ter PCT and R3.1 PCT together with Administrative Instructions 102bis.a) if the RO accepts it:

Any office that does not accept this type of filing may:

The EPO no longer accepts PCT-EASY filings since April 1, 2007 (OJ 2007, 58).

ePCT

This filing method allows filing via a WEB interface if the RO is the IB (link to the site).

PCT-SAFE

WIPO has developed software for online electronic filings (link to the site) with the IB and possibly other RO accepting it.

Other Means

The international application can be filed in electronic format (R89bis.1.a PCT) if the RO accepts this type of filing (R89bis.1.d PCT).

The filing must then comply with the Administrative Instructions, Chapter 7 and Annex F of the Administrative Instructions.

National offices are not required to receive or process electronic applications unless otherwise notified to the International Bureau (R89bis PCT).
