It might be good news for availability and variability if it comes off.
I am pretty sure that many of Kodak's intellectual property claims over the flat grain technology have now expired. I am certain, however, that they still own the "T grain" "TMax" and other associated names. This was a big problem in the 1990s when Foma marketed their 200 and 800 speed films in the US and other western markets as T200 and T800. I am not sure there is any realistic avenue for Kodak to pursue this, but it will be interesting to see what happens.
I will also be very interested to see if Kodak and of the other manufacturers, in their varied states of diminution, do anything, even in terms of a marketing response.
The scanning electron micrograph seems to show a multisize flat grain emulsion; it is interesting, because the mono size technology in TMax and Delta films makes a greater difference for many aspects of performance than the flat or epitaxial grains do. It will be interesting to see what the photos from these look like if they appear.
