If discussions were in the context of their patent claim - i.e. if talking about them being used in a computer printer then large format inks only being mentioned along with a large format printer, and not encouraging their use in smaller printers.
(as an aside/thinking out loud, from what I remember of reading through all the patent documentation, I think I remember it talking about a printer being used with a (attached to a computer), if as mentioned in another thread thee was a way of printing straight from memory card without the need of the computer, this may get around the patent, maybe even printing across wifi would get around the patent, but I would need to reread the documents to check its wording, and how is defined attached, and what it said of the computer and printer relationship. I suppose a lawyer could argue that most modern printers, especially ones with built in memory card readers could be defined as computers in their own right.... thinking...hmm...
It's all a bit muddy but, as I understand it from the discussion on a US forum some years back, the patent has nothing to do with whether a computer is used with the printer or not. It has to do with the printer being a "small format" (desktop) printer.
I believe dye-sublimation inks were already being used in large-format printers prior to the first piezo-printhead desktop printer (introduced by Epson, I believe). The patent probably couldn't be retroactively applied to those large-format printers, so it only applies to small-format desktop printers.
In order to sell dye-sublimation inks for use in a desktop printer, you'd need to have an agreement/license with Sawgrass to do so (which will undoubtedly fix the price to match normal Sawgrass desktop dye-sub inks). In order to sell Sawgrass dye-sublimation inks for use in large-format printers, you probably need to have an agreement/license with Sawgrass to
not sell them at the same "price per ml" for use in a desktop printer. You probably wouldn't need an agreement/license from Sawgrass to sell Brand X dye-sub inks for use in large format printers, unless you wanted to sell them for use in desktop printers, because the patent doesn't apply to large-format printers (nor does it apply to laser printers).
This is why even Sawgrass's standard dye-sub inks will be cheaper for use in large-format printers, because of competition from other brands and why you would not be allowed to sell it at the cheaper price for desktop printers. They don't have to compete with anyone for the desktop printer market because their patent prevents competition in that market, so they can charge as high a price as they wish. In short, the patent is all about keeping the "price per ml" up for the desktop dye-sublimation market - of course it sounds unfair, but anyone who had a legitimate patent like that would use it to make as much money as they could before the patent expired. That's business.
That was my understanding of it but, as I say, it's not very clear so who knows what you're really allowed to do and what you're not allowed to do?
