Philip Morris International Inc. and partner Altria Group Inc. have to stop importing their IQOS heated-tobacco sticks into the U.S. after a deadline passed without any action by the Biden administration to stop it.

Philip Morris and Reynolds America Inc. had each been talking with administration officials since September, when the International Trade Commission ordered the import ban in September after finding that IQOS infringed two Reynolds patents for electrically-powered devices with a heater to generate an aerosol. The order entered a sixty-day presidential review period.
