The photography and printing company's revenue fell to $1.93 billion, missing the analysts' average forecast of $2.11 billion, according to Thomson Reuters I/B/E/S.

Kodak cited a 25 percent decline in digital revenue. Revenue at its consumer digital imaging group, which includes the licensing portfolio, fell almost 40 percent to $731 million.

The results come after a U.S. International Trade Commission judge determined on Monday that a Kodak patent claim against Apple Inc and Research in Motion Ltd is invalid. Kodak filed the complaint in January, claiming Apple's iPhone and RIM's camera-enabled BlackBerry infringe its patent on a method for previewing images.

Kodak reported fourth-quarter earnings of $33 million, or 12 cents per share, from continuing operations, compared with $430 million, or $1.36 per share, a year earlier.

Excluding one-time items, the company reported a loss of 37 cent per share, missing analysts' estimates of a 2-cent loss.

Shares of Kodak were unchanged at $4.52 in trading before the market opened.
