Trial over Apple patent controversy opens in BeijingBeijing, Dec 8 (AZINS) A trial over a patent dispute between Apple and a Chinese phone maker opened Wednesday in Beijing.

Apple and Beijing-based phone retailer Zoomflight are suing the Beijing Intellectual Property Bureau and Chinese phone maker Baili after the bureau demanded Apple and Zoomflight stop sales of Apple's iPhone 6 and iPhone 6 Plus models for alleged patent infringement, Xinhua cited the Beijing Intellectual Property Court as saying.

Previously, Baili accused Zoomflight of selling the iPhone 6 and iPhone 6 Plus models, which Baili claimed had infringed on the patent of its 100C phone models.

The bureau ruled in favour of Baili in May but Apple and Zoomflight appealed against the ruling.

During the Wednesday trial, the plaintiffs and defendants debated about whether the bureau had gone against legal procedures in the process leading up to the ruling.

The trial lasted about seven hours. The court will announce its verdict at a later date.
