Apple suffered a defeat on Friday when a Chinese authority ruled against it on claims some of its iPhones violated patents held by another company.

“What I can tell you there is we’re working with the relevant government agencies and other businesses, and we’re pretty confident and optimistic that we’ll be back online and offering those to our Chinese customers soon,” Cook said on CNBC in May.
Cook was in China last month in an attempt to smooth over tensions there. He also led Apple’s landmark investment in a Chinese competitor to Uber.
Several American tech companies have faced trouble in recent years in China. It’s a problem that has drawn attention from President Obama, who last year said he had personally addressed the issue with his Chinese counterpart.
