Fuji has a product that is "identical" to Polaroid, but due to their technological superiority it is a far better product as they have better control over all aspects of manufacture and have some innovative technology. Kodak went a different route with direct reversal emulsions and a new kind of RDR chemistry that produced the image.
In the offing was a 3000 speed film with superb dye stability. Patents on this can be found using the Kodak unique metallized dyes. If they had won the law suit, the instant photo field would have been a big winner for us all. Polaroid cut it off at the knees.
