CareFirst of Maryland, Inc. v. Johnson & Johnson

On August 19, 2026, WLF urged the Fourth Circuit to affirm a lower court’s rejection of a monopoly claim challenging Johnson & Johnson’s inadvertent acquisition of four patents that it did not know about when it bought another company. WLF argues that Section 2 of the Sherman Act imposes liability for willful acquisition of market power, not market power acquired through happenstance.
