The way U.S. Transportation and Security Administration agents use carts to move around trays at checkpoints to speed the flow of passengers through airport security lines seems almost second nature to frequent fliers at this point.

But if you think back to the early days of flying after the September 11 attacks, you might remember security checkpoints at major airports didn’t always function so uniformly. This Week’s Am Law Litigation Daily Litigators of the Week, Brad Graveline and Laura Burson of Sheppard Mullin, represent SecurityPoint Holdings Inc., the company that holds the patent for the cart-and-tray method that TSA uses at security checkpoints at the nation’s largest airports. Last week, after a damages trial held around this time last year, a judge on the U.S. Court of Federal Claims unsealed a decision handing their client SecurityPoint more than $100 million in damages, finding the government owes their client a running royalty rate of $0.02 per passenger.
