Box No. I in the Written Opinion of the International Searching Authority serves to identify the basis of the opinion. According to MPEP 1845, “Box No. I is used to indicate the basis of the opinion with respect to the language, drawings, sequence listing, and amendments, if any.” This box is crucial for establishing the specific documents and versions that the examiner used to form their opinion on the patentability of the invention.

Specifically, Box No. I includes information on:

  • The language in which the international application was filed
  • Any translations used for the opinion
  • Whether the opinion is based on the description, claims, and drawings as originally filed or as amended
  • If a sequence listing is involved, the form in which it was provided

This information ensures transparency and clarity regarding the exact content that was examined, which is essential for both the applicant and any subsequent patent offices reviewing the application.
