It is recommended that any such observations are filed within three months of publication, as the application may be granted after this time. A major difference between the post-grant revocation procedure and the pre-grant observations procedure is that the person opposing the patent is allowed to take part in the revocation proceedings, but the person opposing the application by filing observations is not allowed to take part in the proceedings.

Observations must be filed in writing in English, French or German and must include a statement of grounds on which the arguments against patentability are based.
