6. Can a divisional application be based on a parent application which is itself a divisional application?  What is the filing date in this situation?

Date Published

The parent application itself may be a divisional application. The filing date of divisional applications is dependent, not upon the date that the new application was filed but the date on which the parent application, was filed or, if the parent application is itself a divisional application, when the earliest application in the chain of divisional applications, was filed.
