Judge Michael R. Barrett

A federal judge in Ohio has temporarily stopped Eastman Kodak Co. from charging different prices for refurbishing a piece of printing equipment depending on whether those customers use Kodak-made ink or a competitor's.

Collins Inkjet Corp. of Ohio sued Kodak in September, alleging the Rochester printing technology company was unfairly trying to claim all the Versamark ink business by telling users of the Kodak-made printing press line that getting printheads refurbished would cost more if they used non-Kodak inks.
