To end a monopoly investigation against it in China, US wireless technology giant InterDigital Communications has pledged to license use of its patents in "fair, reasonable, and non-discriminatory terms", local media reports.

IDC also pledged to withdraw intellectual property complaints with the US International Trade Commission against Chinese telecommunication makers Huawei Technology and ZTE, both headquartered in Shenzhen, Guangdong province.

The anti-monopoly investigation by the National Development and Reform Commission started last June, Xu Kunlin, an official of the commission, said at a press conference in Beijing in February.
