How should priority papers be marked to ensure proper processing?

To ensure proper processing of priority papers, the MPEP recommends marking them with specific information. According to MPEP 215.03:

It is suggested that a notation of the application number of the corresponding U.S. application be placed on the priority papers when such papers are not submitted via a priority document exchange program. Such notation should be placed directly on the priority papers themselves even where a cover letter is attached bearing the U.S. application data.

This practice helps prevent priority papers from becoming separated from their corresponding U.S. applications, which can cause severe problems for both the Office and the applicant. By adhering to this suggestion, applicants can significantly reduce potential issues in processing priority claims.
