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.
