Today is the day that USPTO is pulling the plug on the PDX system with respect to the Chinese patent office. As a consequence, today is the day that, for the first time, a US design applicant can use the DAS system to obtain an electronic certified copy of a Chinese priority design application.

As of today, for a US design filer, the DAS system makes it possible to retrieve an electronic certified copy of a priority application from the following Offices:
Korea became a Depositing Office for designs on July 20, 2018 (blog article). But this is no help for US design filers who wish to claim priority from a Korean design application. Hopefully soon the USPTO will pull the plug on the PDX connection to the Korean intellectual property office, and then US design filers will be able to make use of DAS for Korean priority claims.
