Does anybody know if LEGO has a patent on the 9V connector?  I assume that it

Im not much into the legal stuff, but i think you can get around patent stuff,
by using the connector parts you can get from Lego Service.
No, not those horribly expensive ready-to-use cables with connectors but those
nice connector rails that come in various lengths (about 10 pieces in a bag)
from 2x1(!) to 2x8. I assume that they are intended to be used to connect
multiple electric parts to one power source (eventhough it would be easier to
stack multiple connectors on top of each other).

I used them in my line tracker sensor. By cutting of 2 2x2 parts of a 2x8 piece,
soldering the 2 wires to one of them and stacking (and gluing) it on top of the
other one you get a fully compatible lego connector. And from one bag of those
pieces you can make about 10 connectors.
