Taoyuan, Taiwan - U.S. customs officials have blocked imports of HTC's One X 4G phone for the AT&T network and the Evo 4G LTE for the Sprint network to determine whether they infringe on an Apple patent.
Although HTC did not say how long it expects the customs review to take, the company said, "We believe we are in compliance with the ruling, and HTC is working closely with customs to secure approval."
The review will delay Sprint's planned launch tomorrow of the $199 Evo 4G LTE. For its part, AT&T began selling the $199 One X on May 6, but the carrier hasn't yet responded to an inquiry on how many days or weeks of inventory is available if the review takes an extended time.
The patent in question was part of an Apple complaint before the International Trade Commission (ITC), which last December barred HTC from importing select phones using the patent starting April 19. At the time, HTC said it would modify the phones found to be in violation to eliminate the patented technology.
A customs finding that the two phones are still using the patent could affect imports of HTC's other One-series phones. The HTC One S was supposed to become available through T-Mobile sometime in the spring, and the One V is planned for carriers C-Spire, Cincinnati Bell, MetroPCS, U.S. Cellular and Virgin Mobile. Their prices and availability dates haven't been announced.
A T-Mobile spokesperson, however, said the carrier "does not anticipate any impact to our business regarding availability of the HTC One S."
