Patent myth
“A divisional can be filed whenever I want.”
A divisional must be filed before the parent is granted. Once the parent is granted, the option is gone.
Section 16 permits a further application at any time before grant of the parent, in respect of an invention disclosed in the specification already filed. Since 2024 rule 13(2A) expressly allows a further application based on an earlier further application. But an allowance notice is effectively the last call.
Subject matter described but never claimed in the parent is simply lost - and it is often exactly what a competitor later sells.
