PDF epub DRM Removal is a commercial tool that allows to remove DRM from PDF and ePub ebooks.
Haven't tried to use it, since freeware PDF and ePub DRM removal plug-ins for
Calibre works just fine. Besides Calibre can convert PDF and ePub files to other ebooks formats, so you can read PDF and ePub ebooks whether you use
Kindle,
Sony Reader,
Nook or some other reader.
