1876.01    Request for Rectification and Notification of Action Thereon [R-07.2015]

I.    NOTIFICATION OF DECISION CONCERNING REQUEST FOR RECTIFICATION

The rectification of obvious mistakes is governed by PCT Rule 91. PCT Administrative Instructions Section 325 provides instructions for the processing of rectifications of obvious mistakes by the receiving Office; PCT Administrative Instructions Sections 413 and 413bis provide instructions for the processing of rectifications of obvious mistakes by the International Bureau; PCT Administrative Instructions Section 511 provides instructions for the processing of rectifications of obvious mistakes by the International Searching Authority; and PCT Administrative Instructions Section 607 provides instructions for the processing of rectifications of obvious mistakes by the International Preliminary Examining Authority.

II.    NOTIFICATION

If the applicant requests rectification of any obvious mistakes in the description, claims, or drawings, or in a correction thereon, or in an amendment under Article 19 or 34, the International Preliminary Examining Authority should notify applicant whether the rectification is authorized or refused using Form PCT/IPEA/412. Any rectification offered to the international preliminary examining authority must be in the form of a replacement sheet embodying the rectification and the letter accompanying the replacement sheet must draw attention to the differences between the replaced sheet and the replacement sheet.

The International Preliminary Examining Authority, after fully considering applicant’s request for rectification of an obvious mistake, will notify applicant of the action taken on Form PCT/IPEA/412. Since the space provided is limited, supplemental sheet(s) should be incorporated whenever necessary.
