Procter & Gamble Sues Ranir For Alleged Patent Infringement

Procter & Gamble Co. filed a federal lawsuit claiming that Ranir has infringed on its patented tooth-whitening strips technology. According to P&G, Ranir manufactures its own version of the company's tooth-whitening products and sell them through Walmart, Kroger, and maybe other retailers. P&G's lawsuit focuses on Ranir products packaged for sale under many store brands, such as Kroger's private label and the Equate private-label brand in Walmart stores.
