Eh? Says who? There was a big noise a couple of years ago when some firm which had acquired the patent for the LZW(?) compression used in GIF image files started successfully enforcing said patent. If nothing else, it gave the hitherto lingering PNG format a nice boost.
Legally speaking, the Mobipocket compression scheme is
probably not part of their DRM, so you likely don't have to fear the DMCA, but it may very well be covered by a patent. This patent in all likelihood would also cover a decompression routine for the compressed data.
