I did consider that they might have bought a license from TNP, but if they had, that would not grant them exclusive rights to the icon.
Let's suppose they had bought such a license, and let's call the shared similarity between the LV icon and the FUI icon "X". Let's also suppose that X is copyrightable. The problem is that X is also shared by the TNP icon. So LV wouldn't have ownership of X, and wouldn't have any right to file a DMCA notice based on it.
