In December, the Dutch electronics conglomerate Philips filed a complaint with the U.S. International Trade Commission to allege that Fitbit, Garmin, the distributor Ingram Micro and two Chinese manufacturers, Inventec and Maintek, have been stealing its wearable technology, in violation of section 337 of the Tariff Act of 1930. The commission has agreed to investigate. The patents in question concern activity tracking, alarm reporting and other such features. A ruling favorable to Philips could result in tariffs or bans on any patent-infringing devices. Fitbit has denied the allegations.
