A27. The corrected description, etc. must be prepared in accordance with the formality requirements under the Regulation under the Patent Act so as to avoid discrepancy in the claim numbering, paragraph numbers, drawing numbering, etc. (Notes 14, 16, and 19 of Form 29, Notes 15 and 16 of Form 29-2, and Note 13 of Form 30).

Additionally, if the description, etc. are corrected, the whole text thereof must be attached.
