First, I neither have an eidetic memory or links to the patents nor lawsuit. However.... I remember finding a lawsuit, if I remember correctly, between Samsung and a certain municipality of an unremembered state. The patent involved a lining within surfaces of the washing and drying systems for hospitals which impart silver particles. The marketing part suggested it would spare x amount of bleach and have equal or greater efficacy. The municipal water waste management objected based on the breakdown phase of the sewage relying on bacteria. The silver, they surmised, would obviously hinder this process and so on. Then, as a side note, you have products from waste management called eg Sludge, which is used as fertilizer. Supposedly it is forbidden on vegetable crops, but I once interviewed a cattle rancher who said his subsidies were dependent on his acceptance and use of Sludge. Further aside, the real problem here is the 'forever chemicals' that accompany these products. It tends to permanently compromise the land it's used on. I remember the rancher telling me he's seen his cows chewing on condoms.
