"Kodak will retain a license to use the digital imaging portfolio patents in its future businesses, and for those businesses that it is selling."
So Kodak is actually not selling the patents, but licensing them.
The article also says:
"In the time since, it has withdrawn from the market for consumer inkjet printers, which were once part of Mr. Perezís turnaround strategy, and sold its film business, which had made Kodak a household name."
As far as we know this should be incorrect. Kodak is merely looking for buyers.
