How should the patent documents be revised?

The specific ways to modify claims are generally limited to the deletion and merger of claims and the deletion of technical solutions. The deletion of claims refers to the deletion of one or several claims from the claims.

Claim combination refers to the combination of two or more unrelated claims but subordinate to the same independent claim in the text of authorization announcement, and all the technical features of the combined subordinate claims are combined to form a new claim. In the case that the independent claim has not been modified, it is not allowed to modify its subordinate claims in a combined way. Deleting a technical solution means deleting one or more technical solutions from two or more technical solutions juxtaposed in the same claim.
