Patent Application Number in Japan
Q) Is the Japanese patent application number same as the PCT application number ?
When is the application number notified ?
A) No.
The Japanese patent application number has the format of “2008-0000000″, more precisely “tokugan 2008-0000000″.
The application number is notified 3 to 5 month after the national phase patent application in Japan (national phase entry into Japan).
cf. In case of a non-PCT patent application, the patent number is given immediately after filing patent application.
