It is possible for you to copy and move the entirety of a patent family within a Workspace by just selecting one of it's family members and the method you would do this by is as follows:
Firstly, select the patents within your folder of the patents that you would like to copy/move and then click on the option of "Copy to" or "Move to" depending on the action you would like to perform.
Once you have done this, select the Workspace and constituent folder you would like to move/copy the families to and from the drop-down above, select the type of family that you want to be moved/copied.
