Looking at patent GB2418423A it seems to be very similar to GB2327668
e.g. GB2418423A claim 1 is
- A dispensing device comprising a housing having an upper loading chamber, a dispensing chamber located beneath the loading chamber and a gate means movable between a first, open position and second, closed position to allow s selective communication of the loading chamber and the dispensing chamber, entry to the lower chamber being by means of door means, the device further comprising a locking means which prevents the door means from opening when the gate is in the open position and which prevents opening of the gate means when the door means is open.
whereas GB2327668 states:
- A dispensing device comprising a housing having an upper loading chamber, a dispensing chamber located beneath the loading chamber and moveable gate means adapted to allow selective communication of the loading chamber and dispensing chamber.
Apart from the locking means they seem to be almost identical, so would it be possible to invalidate GB2418423A?
