Three people are beginning jail terms of between 12 and 18 months after an iPad accessories company bribed employees building Apple's latest tablet to obtain pictures of the device.
The case centred on Hon Hai, a unit of Foxconn which builds the iPad 2 and other devices for Apple.
Last year, Xiao Chengsong, former general manager of Shenzhen MacTop Electronics, bribed former Hon Hai employee Hou Pengna for information about the iPad 2.
Hou then used part of the money to persuade Lin Kecheng, a Hon Hai researcher, to get him photos of the iPad 2's cover. He took the photos with a hidden digital camera and passed the pictures, along with other information, back to Hou.
Xiao then used the photos to design and build a series of cases for the iPad 2 and publicised this before the launch, leading to an investigation by state authorities that was followed by the arrests of those involved.
"We cannot comment on matters of internal security, but Foxconn takes its commitment to protecting its intellectual property as well as that of its customers very seriously and undertakes all appropriate actions to safeguard against any violations," Hon Hai told the The Wall Street Journal in a statement.
The Shenzhen Bao'an People's Court sentenced Xiao to 18 months in prison and fined him ¥150,000 (£14,385). Lin got 14 months and a fine of ¥100,000 and Hou received 12 months and a ¥30,000 fine.
