Danaher, their patent, is many times larger (and significantly more diverse) than Pantone which was acquired for $180m in 2007. Adobe should have acquired them then. Assuming no growth they would be worth around $250m now. Well within the reach of Adobe.
I'm referring to Danaher. My point is it's too late. They're not going to sell something that commands $10k for spindles of plastic chips. It prints money.
