How does the Priority Document Exchange (PDX) program work?
The Priority Document Exchange (PDX) program allows for electronic transmission of priority documents between participating foreign intellectual property offices. According to 37 CFR 1.55(i), if the foreign application was filed in a participating office, the requirement for a timely filed certified copy is considered satisfied if the Office receives a copy through the PDX program during the pendency of the application and before the patent is granted.
