I would like to create a VBA UserForm that has a very similar layout to one that is already shipped by Microsoft with Excel. The UserForm is pretty simple: one ListBox, two TextBoxes and around seven Buttons. I would like to use the UserForm as an interface for commercial software. The term layout/design refers here to the arrangement of elements on the UserForm.
My general question is:
Are there any kind of copyrights (or patents) on the layout/design of VBA UserForms?
And in particular:
May Microsoft hold any copyrights of the the layout/design of the UserForms that ship with Excel?
