Can I use PDX for retrieving priority documents from all foreign patent offices?

Can I use PDX for retrieving priority documents from all foreign patent offices?

No, PDX is not available for all foreign patent offices. The availability of PDX depends on:

  • Participation in the WIPO Digital Access Service (DAS)
  • Bilateral PDX agreements between the USPTO and specific foreign offices

MPEP 215.01 states: “The USPTO will attempt to electronically retrieve the priority document through the WIPO DAS (if the foreign office is a DAS depositing office) or through a bilateral PDX agreement.”

To use PDX, check if the foreign office participates in WIPO DAS or has a bilateral agreement with the USPTO. The USPTO maintains a list of participating offices on their website.
