A patent dispute between mobile phone component manufacturers Qualcomm and Broadcom has resulted in an import ban on certain models of phones -- including several potential iPhone rivals.

The U.S. International Trade Commission ruled that certain chips made by Qualcomm violate a patent owned by competitor Broadcom. That's bad news for phone manufactures like Motorola, LG Electronics and Samsung, who had planned to introduce several new mobile phones this summer that use the offending chips and are now barred from being sold in the U.S. until the dispute can be fully resolved.

Several of these phones were positioned to compete with Apple's iPhone, which is set to go on sale June 29.

Specific models affected include the LG touch-screen Prada phone and Motorola's RAZR2.

Qualcomm and Verizon Wireless are expected to request a delay in the ban until they can mount a proper appeal.
