Co-chair of the Product Liability practice group, Kim Branscome is a nationally renowned trial lawyer and litigation strategist who focuses on complex litigation and trials involving product liability, professional liability, environmental and toxic torts, and securities matters. She has secured several high-profile product liability trial victories on behalf of leading multinational corporations across a broad range of sectors, including the pharmaceutical, consumer products, energy and automotive industries. Kim is widely regarded as one of the most talented and respected lawyers in the product liability and mass tort litigation area, with clients describing her as a “rising star” and as “someone clients trust to try their cases.”


Kim has deep experience litigating in federal and state courtrooms across the country, with a particular emphasis on the most high-profile mass torts and product liability matters, as well as high-stakes securities class actions and other complex civil litigation. Kim’s representations include:

  • 3M as lead defense counsel and lead trial counsel, notably securing multiple favorable trial verdicts, in a multibillion-dollar product liability litigation involving allegations that a product sold to the military is related to hearing loss suffered by servicemen and women. The case is recognized as the largest federal multidistrict litigation in U.S. history.
  • GlaxoSmithKline as liaison and lead trial counsel in consolidated proceedings in California involving thousands of claimants who allege that an antacid medication has carcinogenic properties.

  • Aon in a professional liability action arising from damage to the Opry Mills Mall after the historic flooding of the Cumberland River in Nashville.
  • Multiple pharmaceutical industry clients, including Merck, Pfizer, Hoffmann-La Roche and AstraZeneca, among others, in mass tort and multidistrict litigation involving product liability claims related to their prescription medicines.
