What is a continuation patent application?

A continuation patent application is the second (or greater) patent application based on a single disclosure wherein the continuation is filed before the original prior application becomes abandoned or patented.  A continuation may take the form of a continuation patent application, a continuation-in-part patent application or a divisional patent application.  The original application is often referred to as the parent and the successive applications are referred to as children.  The claims in a continuation patent application or divisional patent application have the priority date of the parent patent application.  The claims in a continuation-in-part application may have the parent’s priority date or the filing date of the continuation-in-part patent application.
