Have your lawyer write a good, detailed DMCA complaint to Google and, possibly, cloner's hosting provider -- and make it quick, before they change the copy. If they modify the page later, use archive.org (hopefully it will pick up the current page) or google cache as a proof.
We once DMCAed a Romanian cloner who blatantly copied our top-selling shareware app and refused to take the clone down when I emailed him. His reply was along the lines of "suing is too expensive, you won't sue me".
We sent the DMCA complaint, and a result, he got kicked out of Google and all payment processing services (ShareIt, Regnow etc.) He later emailed me with peace offerings, but I just hit Del.
