The industry for remanufactured printer/toner cartridges has flourished for years as users purchase replacements from third party suppliers who fill a need and offer print supplies at prices significantly lower than those offered by the original manufacturers and OEM’s.

There has been litigation by original manufacturers in the past, premised on third party suppliers infringing patent rights in the cartridges being sold, but the manufacturers seem to have been satisfied in picking and choosing their targets, while permitting the broader industry of third party suppliers to survive.
