TOP STORY: UGG Dupe Trial Will Let Quince Use Dupe Culture Evidence

A California federal judge denied Deckers' bid to keep Quince from referencing dupes and dupe culture at an upcoming trial over shearling boot designs. The case has narrowed from broader trade dress claims to a design patent fight tied to UGG's Classic Ultra Mini boot.
