Proview Technology, which just ended its dispute with Apple over the iPad trademark last month, found itself in another row on July 23 – this time with the law office that helped it win $60 million from the US tech giant.

The Grandall Law Firm has sued Proview for defaulting on attorney fees of its case with Apple, which it claimed to be 15 million yuan ($2.5 million), said Xie Xianghui, a partner at the firm, according to a report by portal website ifeng.com.

Proview Technology, a debt-ridden Shenzhen-based maker of computer screens and LED lights, defended itself and said the money is still at the court's disposal and will be used to pay debt back to its creditors.

The law firm should apply with the court for its fees instead of asking the company for the payment directly, said Yang Rongcan, chairman of the Shenzhen Proview.

Proview has liabilities of HK$1.758 billion ($226 million), according to Caixin Online.
