Kodak said on Friday it may abandon efforts to sell a portfolio of digital imaging patents at auction, and has delayed indefinitely a court hearing to approve such a sale. In a filing with the U.S. bankruptcy court in Manhattan, Kodak said if it was unable to reach acceptable sale terms, it could create a licensing company for the patents as a means to help repay creditors in its Chapter 11 case. It has also been attempting to use its extensive patents to recoup some cash, firing off lawsuits against the likes of Apple, Samsung and HTC.
