The applicant may also request that missing parts of the description and/or missing drawings be included in the application documents by way of a correction according to Rule 139. In virtually all cases this will not be possible (see J 1/82).

In extremely rare cases the other application documents might allow the skilled person to reconstruct the missing parts of the description and/or missing drawings such that they may be filed by way of a correction according to Rule 139.

By contrast with missing parts of the description and/or missing drawings filed under Rule 56(3), corrections under Rule 139 can never be filed by reference to the priority document (see H‑VI, 2.2.1).
