 A company called Excite Worldwide LLC applied for two trademarks with   the US Patent and Trademark Office—one for “Lady Gaga” and one for “Lady   Gaga Fame.” Their application says they’ll produce beauty products and  a line of  jewelry under the brand names.  If their trademark  application is  approved, anyone else will be prohibited from producing  similar items  under that name, including Lady Gaga. The popstar has  nothing to do with Excite Worldwide and says the  Nevada-based company  is getting in the way of her own trademarks, so  she’s suing them. The  lawsuit was filed in New York on Monday and, though we’re no legal  experts, we’re putting our money on Gaga.
