Qualcomm wants to take down the iPhone X due to patent infringement

Qualcomm is targeting Apple's iPhone X with a new batch of patent infringement accusations

American chip maker Qualcomm has entered a vicious court case with Apple after it accused the firm of infringing a number of its patents.

The company believes that Apple has infringed a patent that improves the bandwidth in devices so that the performance of the rear-facing camera is better.

In a court filing, Qualcomm said Apple has also stolen aspects of the Palm OS, despite it being a dead operating system. The firm bought the rights to the software in 2014.

Qualcomm has slammed Apple for using its features on the iPhone X without "license or permission" , and it wants to get the handset banned in the US.

According to a report by Reuters, Qualcomm is looking to take three patent infringement complaints against Apple to court and made a filing on Thursday.

However, in reality, it believes that Apple is using more than 16 of its patents on its iPhones. And it said it wants to halt sales of the handsets.

Both companies have a somewhat troublesome past. They've been in a long-standing dispute over patent infringement complaints, and Apple has just been through a countersuit with Qualcomm.

Although Apple hasn't commented on the situation, it believes that Qualcomm has copied Apple patents in its Snapdragon mobile processors.

In July, Qualcomm went to court because Apple had supposedly used its patents to develop technology to improve iPhone battery life. Again, it wanted to get the devices taken off shelves. But, of course, that hasn't happened yet.

The semiconductor company's latest filings were made in the U.S. District Court for the Southern District of California in San Diego.

As the firm has done in the past, one of the cases is essentially a complaint to the US International Trade Commission to get a ban issued on iPhones. Meanwhile, the other two are cases of patent infringement.

In the filing issued on Thursday, Qualcomm said: "All of these Palm inventions - owned by Qualcomm - have vastly improved the functionality of mobile devices and the user experience, and all of them are widely found in Apple products without license or permission.".

"Apple can import iPhones (regardless of who supplies the modems) that do not infringe the patents asserted in this action, but Apple has no inherent right to infringe Qualcomm's [non-standards essential patents] through the sale of its iPhones.

"Preventing such infringement, and thereby rewarding innovation, is the very purpose for which the patent system was designed."
