Can I access international application files at the USPTO?

Access to international application files at the USPTO is governed by specific rules. According to MPEP 103:

‘International applications that designate the U.S. and have been published in accordance with PCT Article 21(2) are generally open to public inspection and copying.’

This means:

• Published international applications designating the U.S. are accessible
• Access is available after the application’s international publication
• Unpublished international applications are not open to public inspection

To access these files, you can use the USPTO’s Public PAIR system or visit the USPTO’s Public Search Facility.
