I have saved a Patchline from a figure in a variable using findobj function:

figure(1);
patchVar = findobj(gcf, 'type', 'patch');

now, how can I plot that in another figure?

You have to re-plot it with a second patch call:

x = linspace(-1, 1);
y1 = 1.5*x.^2+1;
y2 = x.^2 + 1.5;
figure(1)
patchVar = patch([x, fliplr(x)], [y1 fliplr(y2)], 'g');                 % Create ‘patch’ Object
figure(2)
patch(patchVar.XData, patchVar.YData, patchVar.FaceColor)

Also, you do not need the findobj call (although it works, and returns the same information as the handle), you can simply create a handle to the original patch object.
