Chapter 22 Clerical and Administrative Procedures
Handling of Paper Submission by Authorities Requiring Electronic Submission
22.51A If the International Searching Authority or the International Preliminary Examining Authority only accepts submissions in electronic form or by electronic means under Rule 89bis.1(d-bis), it treats any documents submitted to it on paper as not having been received. The Authority promptly notifies the applicant accordingly (Form PCT/ISA/231 or Form PCT/IPEA/435). Nevertheless, the Authority may decide in a particular case to accept any documents submitted via other means (Sections 703(e-bis) and 713).
