I get a yellow or red validation message when I try to attach PDF files to my PCT application. What should I do?

The rules on attaching PDF files under the PCT procedure are even stricter than under the EP procedure, so please ensure that your PDF documents meet the following requirements:

  • Adobe Portable Document Format version 1.4 compatible
  • non-compressed text to facilitate searching
  • unencrypted text
  • no embedded OLE objects
  • all fonts embedded and licensed for distribution

If the problem persists, contact us or WIPO directly.

To ensure that the PDF you have created will be accepted by the Online Filing software, you can use the Amyuni PDF converter. Please contact us about this.
