I've read around and see this a great news for film, considering the alternative. Kodak management is working hard not to be bought out and have its parts sold off. By selling patents off they seem to be buying time until that can finish a restructuring and bring it back to profitability.
I see selling the patents rather than selling the company as the better deal for film and film users.

The 3 billion dollar number seems a bit high for the patents. Big players have already stocked up their patent arsenal. They will go at a much lower price to a patent troll company or similar outfit.

P.S: The pension shortfall appears to be much higher than is reported by the company. This will scare away some buyers of the firm.
