Apple has a some big problem is China and with competitor Qualcomm. On Monday, Qualcomm announced a lawsuit they filed against Apple in China is officially underway, and that Apple must stop selling a large majority of their products in the country.

Qaulcomm believes that Apple is infringing on their patents and selling iphones illegally.

“We deeply value our relationships with customers, rarely resorting to the courts for assistance, but we also have an abiding belief in the need to protect intellectual property rights,” said Don Rosenberg, executive vice president and general counsel, Qualcomm Incorporated. “Apple continues to benefit from our intellectual property while refusing to compensate us. These Court orders are further confirmation of the strength of Qualcomm’s vast patent portfolio.”

Qualcomm says the patents Apple is ignoring have to do with allowing consumers to adjust and reformat the size and appearance of photographs, and to manage applications using a touch screen when viewing, navigating and dismissing applications on their phones.

China is just the start of lawsuits against Apple. In a press release Qualcomm says they are looking at taking more legal action in other countries and jurisdictions around the world.

The ban affects all iphone model starting with the 6S and ending with the iphone X.

CNBC reports that Apple, in response to Qualcomm’s lawsuit, has filed an appeal to reverse the Chinese Court’s decision. Apple claims that their products, installed with new software, do not infringe on any patents, and call this lawsuit desperate.

“Qualcomm’s effort to ban our products is another desperate move by a company whose illegal practices are under investigation by regulators around the world,” Apple said in a statement earlier Monday. “All iPhone models remain available for our customers in China. Qualcomm is asserting three patents they had never raised before, including one which has already been invalidated. We will pursue all our legal options through the courts.”
