patterning mirrored features

i am modelling a computer case which has four feet fitting along a curve.  these feet are asymmetrically patterned, and i want to use mirror on the inital foot drawn to save redrawing.  however, using a linear pattern on this mirrored feature causes the original foot to be patterned as well.  is there any way to pattern just the mirrored feature without the orignal?  thanks
