Major technology companies have aligned against Qualcomm in its legal dispute with Apple by calling on regulators to reject Qualcomm's bid to ban the import of iPhones.
A lobbying group that represents Alphabet's Google, Amazon.com, Microsoft and Facebook filed comments with the U.S. International Trade Commission.
They argued that barring Apple from importing foreign-assembled iPhones that use Intel Corp chips - as Qualcomm has requested - would cause "significant shocks to supply" for phones and would hurt consumers.
Intel and Samsung are members of the group, called the Computer & Communications Industry Association.
"If the ITC were to grant this exclusion order, it would help Qualcomm use its monopoly power for further leverage against Apple and allow them to drive up prices on consumer devices," Ed Black, the CEO of the group, said in a statement. "What's at stake here is certainly the availability of iPhones and other smartphones at better prices."
Qualcomm and Apple have been locked in a sprawling legal battle in which Apple has objected to Qualcomm's business model of requiring customers to sign patent license agreements before buying chips.
In turn, Qualcomm has accused Apple of directing its contract manufacturers like Foxconn to withhold license payments in a bid to hurt Qualcomm. The conflict has taken a toll on Qualcomm's profit outlook.
Earlier this month, Qualcomm sued Apple on separate allegations that Apple infringed patents around making iPhones work better without draining the battery.
Qualcomm also filed a complaint with the U.S. ITC seeking to ban iPhones that use chips "other than those supplied by Qualcomm affiliates."
