The suit stemmed from Colgate’s allegations that P&G’s advertising for its highly successful at-home tooth-whitening products, Crest Whitestrips and Crest Night Effects, were false under the federal Lanham Act. Obtained a complete defense verdict for Procter & Gamble after a three-week jury trial.
  • Defending GlaxoSmithKline (GSK) against a preliminary injunction motion based on allegations that GSK commercials for Nicorette gum and NicoDerm CQ patches were false and violated the Lanham Act.
