Two weeks after suing Research In Motion (RIM) for patent infringements and a week after RIM said it would start selling BlackBerrys in China, Visto Corporation said Monday it, too, was moving into the Chinese market.

Visto said in a statement that it was teaming with a subsidiary of Lenovo Group to offer its mobile e-mail products in China. Specifically, Visto said that its agreement is with Lenovo Chinaweal System & Service Co., Ltd., which is a leading IT vendor in China. That company will offer the Visto Mobile product to enterprises, the company said.

The software, which will be available both in Chinese and English, will work on about a dozen mobile devices that have been widely deployed in China, Visto said. The company compared that wide range of devices to RIM's initiative, which involves only BlackBerry devices.

"This service is the first of its kind in China and, unlike competing mobile e-mail offerings, the Visto Mobile solution is available immediately on a broad range of mobile devices," Brian Bogosian, president, Visto's chairman and CEO, said in a statement.

The company said that it already has commitments from several large Chinese enterprises for the mobile e-mail software but did not specify which ones.

Visto filed a suit in federal court on April 28 claiming that RIM violated Visto's patents regarding mobile e-mail. RIM previously paid a $612.5 million patent settlement to NTP Inc.
