P&G files infringement complaint against Ranir

Procter & Gamble said it filed a patent infringement complaint and motion for preliminary injunction in the US District Court for the Southern District of Ohio against Ranir LLC, a store-brand manufacturer and distributor of tooth whitening products.

“The complaint alleges that Ranir is infringing P&G’s patented tooth whitening technology by manufacturing and selling store-brand tooth whitening strip products to retailers,” said P&G.

“Consistent with previous cases of Crest Whitestrips intellectual property violations, P&G will take steps necessary to protect its intellectual property.

“Just last year, the court permanently enjoined another store-brand manufacturer from manufacturing, offering, selling, or distributing products that infringe P&G’s patents or its Crest Whitestrips trade dress or trademarks.”
