Answer: Actually remanufactured cartridges are built from a one time used original cartridges , if you chose remanufactured you are saving costs and protect environment , clones are built newbuilt non-OEM toner and inkjet cartridges. Most of these products are produced in China and other South East Asian countries. They are normally very similar, or even identical, to the original cartridges produced by the original equipment manufacturer (=hereafter OEM). But as OEM cartridges are often (partially) patented across Europe, many of these newbuilt non-OEM cartridges infringe one or more OEM-patents or design rights.
So make sure that you only buy cartridges that have been remanufactured in accordance with the law.
