HTC's phones are a bit too close to Apple's iPhone, according to the ITC.
The International Trade Commission has given Apple the victory it had been seeking against HTC.
The organization ruled tht it would impose a limited import ban on some HTC phones starting April 19.
The ban won't go into effect until April 19, to give U.S. carries a chance to adjust to the ban and it also must still survive a presidential veto.
In the ruling, the commission ruled that HTV violated tariff laws by importing phones that violate patents owned by Apple.
The suit is part of a larger battle that smartphone-makers are carrying out against each other across the globe.
