It is a bit late for any blackcurrant to produce fruit I would think. Have you seen any flowers on it? they are very insignificant and usually appear around May time on my bushes.
Maybe your plant is too young? If you started your garden this year and planted the bush, to be honest I don't think you should expect any fruit until next year at the very earliest. You don't usually need a second variety for pollination, but I'm not sure about the variety you have - some do need a second variety I think. It wouldn't hurt to get another to make sure. As for propagation, yes they are very easy, sometimes cuttings just poked into the ground take root!
