Eastman Kodak Company is suing Fujifilm Corporation, claiming that some of its Japanese rival's cameras infringe its patented digital-imaging technology.

The lawsuit, filed on Friday in US District Court in Rochester, New York, claims Fujifilm is infringing five separate Kodak patents related to various aspects of capturing, storing, previewing and transmitting images.

The company move to defend its intellectual property come at a time when the spectre of bankruptcy protection is looming over its head.

At the beginning of the week, Kodak sued Apple and HTC Corporation claiming some of their smartphones, tablets and other devices infringe Kodak patents related to transmitting images.

The ailing photography pioneer has relied on patent licensing fees and lawsuits to collect $1.9 billion since 2008.
 
Kodak shares fell 15 cents, or 22.3 percent, to close at 52 cents.
