Regardless, we should respect their claim. I agree with the basic idea: it was the result of a creative process, and they choose to keep that as proprietary IP. Therefore mpl will not include a clone of this color map. If a user decides to make and use a clone, that's their business, not ours. We shouldn't encourage it. > > The only things that bother me in this IP claim, is the status of all > the plots produced with this colormap. They are in a sense a > /derivative/ work, am I right ? So the question becomes : does Mathworks > owns IP right for all these plots ?! Perhaps they could claim copyright infringement; but from the mpl perspective, I don't think it matters. The question will only arise in practice if a user makes a plot with a clone of parula, and Mathworks chooses to turn it into a legal issue. I think it is unlikely this will happen; but if and when it does, I don't think mpl will be involved. We will not be supplying the colormap or in any way encouraging or condoning its use in mpl, unless and until Mathworks releases it.
