Why must the claims in the U.S. application correspond with the "allowed" application?

The claims in a U.S. application must correspond with the "allowed" application primarily to avoid redundancy in patenting. This principle is essential to ensure that the same invention is not claimed in multiple patent applications, which could lead to overlapping protections and confusion in the patent system. By ensuring that the claims align with those that have been allowed, the patent examiner can confirm that the application is seeking protection for the same invention described in the earlier allowed application, which helps streamline the examination process and maintain the integrity of the patent system.

A focus on avoiding redundancy is crucial not only for the efficiency of the examination but also for the clarity and distinctiveness of patents. Each claim should contribute uniquely to the protected invention, preventing unnecessary duplication of efforts in protecting similar inventions.

In contrast, while ensuring novelty, expediting the examination process, and compliance with international laws are important aspects of the patent process, they are secondary to the primary goal of managing patent claims to avoid redundancy.
