Regulators in Beijing have ordered Apple to halt its sales of the iPhone 6 and Plus in the city after it found the U.S. tech giant infringed on patents held by a Chinese rival.

According to the ruling, Apple’s design violated a patent held by Shenzhen Baili for the exterior design of its 100C smartphone.

Bloomberg said the ruling applies only to Beijing rather than the entirety of China, but noted the precedent could spell trouble for Apple in future cases.

The ruling is the second loss Apple has faced in Beijing court in as many months.

In May, Apple also lost its bid to make the “iPhone” name exclusive to its products, according to a Bloomberg report. The court instead ruled in favor of an accessories-maker, giving it the right to use the “iPhone” name on leather goods. Apple was able to maintain the trademark name for mobile devices.

The decision comes amid broader struggles for Apple, as it fights to boost sagging smartphone sales. The company, however, has come up against a wall in its attempts to open up the India market for its devices.

For the quarter ended in March, Apple reported its first drop in quarterly revenue in more than a decade and its first-ever year-over-year drop in iPhone sales. During that period, Apple’s revenue in Greater China slid 32 percent sequentially and 26 percent year over year to just $12.5 billion.
