Judge Claude Vallet, who deals with urgent cases at Paris's Court of First Instance, found that the packaging by Serge Mansau, composed of three half-spheres atop each other, was too similar to a design registered by Jean-Claude Cardiet of Paris firm Cardiet Design.
Guerlain must therefore stop production of the packaging within 15 days of the judgement, dated October 20, although it has not been ordered to take existing bottles of the fragrance off the market. (via cosmeticnews)
Oops. I didn't love the bottle anyway; it didn't look very Guerlain-ish.
Update 11/3: As you might expect, Guerlain has filed an appeal. (via Yahoo News)
Update 12/20: Cardiet Design dropped their lawsuit.
