What must be submitted along with amended claims in a PPH application?

When submitting amended claims in a Patent Prosecution Highway (PPH) application, it's essential to include a statement certifying sufficient correspondence between the claims in the PPH application and the claims that were previously allowed by the patent office that made the original examination. This requirement ensures that the applicant verifies that the amended claims correspond closely enough to the claims that have received a favorable examination outcome, which paves the way for expedited processing.

The requirement for this certification stems from the underlying purpose of the PPH, which is to utilize work that has already been done by another patent office to expedite the examination process. By ensuring that there is sufficient correspondence, the patent offices involved can maintain consistency and efficiency in their examination processes.

In contrast, while requests for expedited reviews and lists of previous rejections may be relevant to overall patent prosecution, they do not specifically address the need to indicate how the claims correspond to previously examined claims. Additionally, a certification that claims do not correspond is not required in the context of PPH applications, as the emphasis is on demonstrating that the claims do correspond sufficiently.
