The EPO as receiving Office will process requests for correction of an element or a part which is not furnished for the purpose of incorporation by reference, since this option is not covered by the notification of incompatibility referred to in GL/PCT-EPO A-II, 6.[R. 20.5bis(b); (c); ]
The procedure to be followed varies depending on whether the correction is requested either on/before the date on which the requirements under Art. 11(1) for the accordance of an international filing date are fulfilled (see GL/PCT-EPO A-II, 6.1.1) or after that date (see GL/PCT-EPO A-II, 6.1.2).
