In addition to the petition, what specific document related to the corresponding application must be included when applying for PPH?

When applying for the Patent Prosecution Highway (PPH), a key requirement is to provide a copy of the office action prior to the notice of allowance. This document is essential because it typically contains the examination history of the application, showing how the claims were assessed against the patentability criteria, such as novelty and non-obviousness.

The office action serves as a basis for justifying the request for accelerated examination under the PPH, as it reflects the findings of the foreign patent office on the same or corresponding application. By including this document, applicants provide the necessary context and evidence that supports their claims have been favorably reviewed during the examination process.

In contrast, other documents that could be included, like the allowed claims or limitations, may not provide the same depth of insight into the examination process as the office action. The allowed claims alone do not detail the reasoning behind the decision, and while the first communication may contain valuable information, it is not specifically mandated by PPH rules. Consequently, the office action prior to the notice of allowance is crucial for facilitating a smooth and efficient examination in the PPH process.
