Even as the specter of bankruptcy protection looms, Eastman Kodak Co. is intensifying its efforts to defend its intellectual property.
In a lawsuit it filed here Friday against Fujifilm Corp., Kodak claimed some of its Japanese rival's cameras infringe its digital-imaging technology. At the beginning of the week, Kodak sued Apple Inc. and HTC Corp. 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's stock slumped Friday amid renewed fears that the 132-year-old business icon is preparing to seek bankruptcy court protection from its creditors.
Based on Rochester, New York, Kodak has amassed more than 1,000 digital-imaging patents, and almost all of today's digital cameras rely on its technology.
