Fujitsu has laid claim to the iPad brand within hours of Apple unveiling its latest gadget under that name.
The Japanese technology company's iPad is a mobile device for verifying the price of retail goods, checking inventory data and confirming sales.
The Fujitsu iPad has a colour touch-screen, an Intel processor, wi-fi and Bluetooth connectivity, and supports VoIP telephone calls.
"It is our understanding that the name is ours," Fujitsu's public relations director Masahiro Yamane told the New York Times.
He said the company is consulting lawyers about what to do next.
But Fujitsu was not the first to apply for the iPad trademark. Its 2003 application stalled because of an earlier application by security firm Magtek for its mobile encryption device.

Fujitsu renewed its application to the US Patent and Trademark Office in June 2009, but a month later Apple applied for an international trademark for the iPad.
Apple has since filed numerous requests for more time to oppose Fujitsu's applications, but currently has until 28 February to make its case.
If Apple manages to fend off Fujitsu, it may be just the first in a string of hurdles the company has to face.
German firm Siemens also uses the name iPad for engines and motors, and Canadian lingerie maker, Coconut Grove Pads, has the right to market iPad bras.
