Electronic Priority Document Exchange (PDX)
In January 2007, the United States Patent and Trademark Office (USPTO) implemented a procedure for direct electronic priority document exchange with participating foreign intellectual property offices. Effective April 20, 2009, the World Intellectual Property Organization (WIPO) will become the fourth foreign intellectual property office to participate in the PDX system. See 37 CFR 1.14(h) and 1.55(d). The USPTO will have the ability to begin electronically retrieving priority documents from the WIPO through the Digital Access Service (DAS) for Priority Documents. Similarly, the WIPO will also gain the ability to electronically retrieve U.S. priority documents from the USPTO through the Digital Access System (DAS). This page contains links to important information regarding the implementation of PDX and DAS.
