Kodak had put a total of 1,100 imaging patents on sale more than a year ago, but has been unable to close any deals due to lawsuits over the validity of the patents and the bankruptcy procedures after its Chapter 11 filing in January this year. While he company estimated the total value of patents at more than US$ 2 billion, media reports say that the bids of companies like Apple, Google and Microsoft were significantly below these estimates. Kodak declined to comment on any details of the auction, citing confidelity agreements.
