Application skills of two invention patents

Although you mentioned Patent A and Patent B, according to your description, the contents of the two patents are exactly the same, and they are actually one patent. I don't know why you applied for a patent twice. Isn't this a waste of money? If you simply pursue the number of patents, you can write a method A and a method B, so that no matter how many applications, you can get authorization at the same time. Let's talk about the two methods you proposed first. For the method (1), write A first, and then apply for A and B. If the latter application date is later than the first application date, the examiner will directly use the first application method to comment on the novelty of the latter application method, so the latter application can only authorize the latter method. If the latter application date is earlier than the first application date, the examiner will use the conflicting application to comment on the novelty of the latter application method. For method (2), the probability of applying for two identical patents at the same time and obtaining two patents at the same time exists, but it is very low, which requires that two patent applications be assigned to two different examiners, and the two examiners need to issue authorization notices almost at the same time (this requires that neither examiner knows that the other has been authorized, but in this case, the examiners may communicate with each other or wait for a period of time. See if the other one is authorized before deciding whether to authorize this one. ) If two patent applications are assigned to an examiner and only one application is authorized, you can give up the other application (or let you give up part of each patent application, such as one application giving up A and the other giving up B). If two applications are assigned to two examiners, and one of them authorizes first, then the other examiner will definitely let you make a choice, either giving up authorization or giving up this one in your hand, so on the whole, the final result is the same as your first application for writing A and the other application for writing B.
