I don't think the UCI has any say on that unless a team tries to copyright a particular design style. Otherwise, they'd have had to bring out injunctions against the Continental equivalents of Rabobank, Milram, Katyusha (maybe not Katyusha) and Liberty Seguros because they are, by the eyes of officialdom, completely separate teams from their ProTour equivalents. And what of those Colombian teams whose jerseys look suspiciously like European teams, such as Duitama-Club Omni? Or the historic 'twin teams' of Boyacá?
