Qualcomm is now suing Apple’s suppliers too, including Foxconn

The dispute between Apple and Qualcomm is continuing to get uglier, with the chip maker now going after Apple's supply chain in court. Qualcomm has already filed a countersuit against Apple itself but now, the company is also going after four of the companies Apple uses to supply components for the iPhone, including Foxconn.

The legal troubles began earlier this year, when the US Federal Trade Commission announced that it would be taking Qualcomm to court over anti-competitive business practises. The FTC's lawsuit was based on complaints from Apple but recently, Samsung and Intel have also backed the commission. Apple went on to file its own separate lawsuit against Qualcomm and is said to be withholding around $1 billion in licensing fees while the legal dispute is underway.

According to a report from Reuters, Qualcomm has now filed claims against Foxconn and three other companies that currently hold contracts with Apple. According to Qualcomm, these companies have all failed to pay patent royalties, the chip maker also things they are doing so under Apple's orders.

In the meantime, Qualcomm has also filed an injunction in an effort to get the US to block Apple from importing any more iPhones.

KitGuru Says: At this point, it seems the dispute between Apple and Qualcomm is escalating every week. This case certainly isn't going to be over any time soon…
