Query the original patent by priority

Because this China application contains all or part of the previous three Japanese applications, he can claim the priority of these three Japanese applications.

In addition, the original application document as priority may not be made public, so it may not be found. If it is public, it can be found at this address of the Japan Special Bureau:

http://www4.ipdl.inpit.go.jp/Tokujitu/tjsogodben.ipdl? n 0000 = 1 15

Supplement: If it is not made public, it is impossible for you to find the original text. In addition, pay attention to the above description. Class A documents indicate the patent WeChat official account, and the priority number is the application number, not the WeChat official account, so the number you entered has nothing to do with the original documents.
