FMC company Calypso Wireless has filed a patent infringement lawsuit against T-Mobile USA, charging that the operator violates its patent pertaining to how T-Mobile switches callers between GSM and WiFi connections.
T-Mobile’s HotSpot@Home service has been in operation since June 2007, and has been steadily increasing the number of devices that can take advantage of the service. T-Mobile said in a statement that “based on its preliminary review the company believes that Calypso Wireless’s allegations are without merit.” T-Mobile said it intends to defend itself vigorously in this case.”
Patent number 6,680,923 details how a device could seamlessly switch between two networks while maintaining the same connection, which could prove to be bad news for other UMA service providers, like Rogers and their Talkspot program. It’s a growingly-popular service, and Calypso in a good position to cash in with infringement claims. Their president, Richard Pattin, was pretty smug about the whole thing.
“This is a significant turning point for Calypso, as we believe it will open the doors for hundreds of millions of dollars in licensing opportunities. Calypso has invested significantly in the discovery, development and continued advancement of FMC. When others make use of our patented technology, we will continue to take aggressive action including the enforcement of our legal rights.”
