Based on my historical understanding of intellectual property law,
Rosco *could not be* exercising any IP rights over the letter R, any more than Intel was permitted to over x86, which is why the 586 was released as the (trademarkable) Pentium
Processor.
Thereby, they could only be exercising IP rights over the arbitrary mapping of colors into numbers, which that
EOS "sidestep" does not actually side step, and hence wouldn't protect them.
In short, with all due respect to both
ETC and LD's,
ETC seems to be trying to have it both ways here, and I'm not at all sure how I want that to turn out.
In fact, though, the last graf of that notice seems to suggest that, in fact, if you have shows pre 3.2 saved with R numbers on
LED fixtures, that those colors will fall off when you load them in to >=3.2 desks, and that supports the assertion I made: if you're using
Rosco colors, don't upgrade your
desk (to 3.2), or those show files won't load properly. ("removed assets may affect...ML Controls"; specifically,
RGB colors derived by lookup tables from "R32".)
Why isn't that the correct interpretation of the available data, Scott?
