24 Aug 2017 --- Norwegian biotechnology company Rimfrost AS, supplier Rimfrost Sublime krill oil, has announced that the US Patent and Trademark Office has issued four decisions finding that a reasonable likelihood exists that every claim of two patents owned to Aker Biomarine Antarctic AS are unpatentable. “We are gratified that the US Patent Office has instituted Inter Partes Review proceedings of the Aker patents,” says Rimfrost owner Stig Remøy. “It confirms Rimfrost’s longstanding belief that the Aker patents are not valid and should have never been issued in the first place.”
