Fashionistas who have been watching the acrimonious trademark battle between Christian Louboutin S.A. and Yves Saint Laurent for the past year and a half may have to find another lawsuit on which to focus.  In September, the United States District Court for the Second Circuit determined that YSL’s monochromatic red shoe/red sole combination did not infringe any of Louboutin’s trademarks, but preserved Loutboutin’s claim of trademark rights when its red sole is paired with a contrasting color.  See For Louboutin and Yves Saint Laurent, Both See Red.  On the heels of that Solomonic decision, YSL has now moved to voluntarily dismiss its four counterclaims against Louboutin seeking cancellation of Louboutin’s trademark registrations without prejudice, and its counterclaims for tortious interference and unfair competition with prejudice.  The basis for requesting dismissal of the cancellation claims without prejudice is YSL’s assertion that the district court lacks subject matter jurisdiction over those claims now that judgment has been directed in YSL’s favor on all of Louboutin’s federal trademark claims.  See Nike, Inc. v. Already, LLC, 663 F3d 89, 94, 98-99 (2d Cir. 2011), cert. granted, — S. Ct. —, 2012 WL 425184 (2012).  It will be interesting to see Louboutin’s response to the motion which, if granted, leaves open the ability of YSL to challenge Louboutin’s trademarks before the Trademark Trials & Appeals Board.
