A court in China has ordered Apple to pay $165,000 in compensation, to a Chinese publisher for copyright violation, according to the official news agency Xinhua.
They had claimed that unlicensed electronic versions of their books had been sold on Apple's online store.
This is the second time Apple has been fined for copyright violation in China. In September, a Chinese court ordered Apple to pay compensation of 520,000 yuan to a Chinese encyclopaedia publisher for alleged copyright violation. The US technology firm has appealed against that decision.
Spokeswoman for Apple, Carolyn Wu, who confirmed the fine, said the company takes "copyright infringement complaints very seriously". "We're always updating our service to better assist content owners in protecting their rights," she added.
Earlier this year, Apple faced a lawsuit from a Chinese firm Proview, which claimed that it owned the rights to the "iPad" name in the Chinese market after registering it in 2000, but Apple said it had bought the global rights to the "iPad" from Proview's Taiwanese affiliate for $55,000.
