CPC B64F2700/6284 was a patent subclass.
The class was abolished, and severely deprecated. The usual formatted links to espacenet and USPTO don't work to bring anything up about it. This document , page 60, says the category was abolished in 2017, and that patents in this class were to be moved to B64F1, B64F3, and B64F5, but it does not say what the subclass's content was before.[1]
Because we have several patents identified in this class we may be able to figure out what it was for.
