What modifications are allowed to the patent documents of inventions and utility models in the procedure of invalidation of patent rights? What is the principle of modification? What are the modification methods? The modification of the patent document for invention or utility model is limited to the claims, and its principle is:

(1) The title of the original claim shall not be changed.

(2) Compared with the authorized claim, the protection scope of the original patent shall not be expanded.

(3) It shall not exceed the scope recorded in the original specification and claims.

(4) In general, technical features not included in the authorization claim shall not be added.

On the premise of meeting the above-mentioned modification principles, the specific ways to modify the 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 more claims from the claims, such as independent claims or dependent claims.

The combination of claims refers to the combination of two or more claims that are not related to each other but belong to the same independent claim in the text of authorization announcement. In this case, the technical features of the merged dependent claims are combined to form a new claim. The new claim shall contain all the technical features of the merged subordinate claims. 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.
