A Southern California law firm has sued Kimberly-Clark Corp for more than $500 million, alleging that the Kleenex tissue maker committed fraud by marketing and selling some of its surgical gowns as protection against Ebola.

Law firm Eagan Avenatti said it filed a class-action lawsuit in a Los Angeles court on Wednesday, stating that Kimberly-Clark had falsely represented to health regulators and healthcare workers that its “MICROCOOL Breathable High Performance Surgical Gowns” are impermeable and provide protection against Ebola.
