What should I do if two utility model patents with the same name and different patent numbers are found indistinguishable in the first instance and cannot be modified accordingly?

Before applying for a patent, it is suggested that each patent should have its own case number. After receiving the acceptance notice, the patent application number and application date should be recorded in time, so that this will not happen. The contents of the two patents are definitely different. We should also be able to distinguish which patent it is from the contents of the notice of examination opinions. If not, call the examiner to confirm.
