The same technical scheme applied for the invention and utility model patent on the same day, and patent B voluntarily withdrew the application, so does patent A also need to be withdrawn?

Hello, you said that the withdrawal of patent B, patent A does not need to be withdrawn, and the review of A and B is independent. The reason why it is stated that the invention patent has been applied at the same time is to avoid repeated authorization;

"Item" refers to one of the claims, that is, the claim marked "1, 2,3 ...". . If the priority of several claims is claimed, each claim must be submitted to 80 yuan.

It should be noted that if the application for the modified patent B is withdrawn, the content added during the modification cannot claim priority.

I hope it helps you ~
