Apple was down about 2 percent Monday morning after a Chinese court banned the import and sale of most iPhone models in the country as part of an injunction. Qualcomm requested the injunction for alleged patent violation and announced the news in a statement Monday morning.

Qualcomm alleged that Apple violated two patents it holds on features that lets users reformat the size and appearance of photos and manage applications on a touch screen when navigating through phone apps. The two preliminary injunctions were granted by the Fuzhou Intermediate People's Court in China. Apple says it did not violate these patents and that the ban goes beyond the scope of the injunction itself.
