Can the patent name of the divisional application be different from that of the parent case?

Of course. The name of the divisional patent application may be different from the name of the parent patent. When a patent application contains multiple inventions, a divisional application can be filed on the basis of the parent case. A divisional application needs to separate one or more inventions from the parent case and assign them a new patent name. This new name can be different from the name of the parent case, so as to describe the invention-creation involved in the divisional application more accurately. The divisional application must be closely related to the original parent case application, and the technical scheme involved should be consistent with the parent case. In the whole application process, it is also necessary to ensure that the content of the divisional application is clearly distinguished from the parent application to avoid the problem of repeated application or patent protection.
