The Rochester, N.Y., company filed for Chapter 11 bankruptcy protection in January after struggling to adapt to the shift to digital photography. Eastman Kodak Co. said Wednesday the patent sale will help it repay a substantial amount of its initial debtor-in-possession loan, and it satisfies a key condition of new financing that required the sale of the patents for at least $500 million. In November, Kodak said it would receive loans worth $830 million in a new, cheaper financing package, replacing a $793 million deal.
