(3)
No further amendment may be made without the consent of the Examining Division. 
(4)
When filing any amendments referred to in paragraphs 1 to 3, the applicant shall identify them and indicate the basis for them in the application as filed. If the Examining Division notes a failure to meet either requirement, it may request the correction of this deficiency within a period of one month.

Amended claims may not relate to unsearched subject-matter which does not combine with the originally claimed invention or group of inventions to form a single general inventive concept. Nor may they relate to subject-matter not searched in accordance with Rule 62a or Rule 63.
