Kodak loses second round in patent case

The U.S. International Trade Commission on Friday upheld a May 21 ruling by Judge Thomas Pender of that agency that neither Apple nor RIM had violated Kodak's rights in the so-called '218 patent, which covers how digital cameras preview images.

"The investigation is thus terminated," the agency said.

Kodak has been hoping to recover $1 billion, and said on Sunday it plans another appeal, this time  to the U.S. Court of Appeals.

"The validity of the '218 patent has been upheld in previous litigation at the ITC and was affirmed by the U.S. Patent and Trade Office in the face of two separate challenges," it said. "We are confident that its validity will ultimately be upheld."

Kodak filed Chapter 11 bankruptcy for protection from creditors in January. Patent litigation has in recent years been a major part of the  company's strategy to generate revenue. It is based in upstate Rochester.

Apple's products include the iPhone, while RIM makes the BlackBerry.

Last month, Kodak won bankruptcy court permission to sell more than 1,100 digital imaging patents, roughly one-tenth of its patent portfolio, to help repay creditors as it shifts its business focus toward printing.

These patents are part of Kodak's digital-capture portfolio for devices such as digital cameras, smartphones and tablets. That portfolio has generated more than $3 billion in revenue since 2001.

Kodak has said it expects to hold the auction early next month.
