Kodak on Tuesday mentioned that it was seeing very strong interest after raising the possible selloff of its patents. The "phone started to ring" almost immediately afterwards and had led to a significant number already having signed non-disclosure agreements for secret negotiations. While CEO Antonio Perez wouldn't name customers, he told Bloomberg that Kodak wanted a deal with cash up front as well as a pact that let it keep a license to use the primarily phone-focused camera technology that it would otherwise be giving away.
