Calypso Wireless has filed a patent infringement complaint against T-Mobile USA, accusing the mobile operator of breaching a patent it holds which allows "seamless switching" between GSM and Wi-Fi services
Calypso owns U.S. Patent 6,680,923 ('923 Patent) and the proprietary ASNAP (Automatic Switching of Network Access Points) technology. Calypso says that its proprietary switching technology allows a user to seamlessly switch and connect from either a Cellular Network or a Wireless Local Area Network Access Point (WLAN) seamlessly without the user noticing the change.
In the lawsuit, Calypso seeks to obtain past and future damages, attorney's fees, and an injunction prohibiting T-Mobile from continuing to sell or make use of the inventions embodied in the '923 Patent. The case relates primarily to T-Mobile's Hotspot@Home product, which allows subscribers to seamlessly switch from the GSM network to local Wi-Fi hotspots.
Richard Pattin, President of Calypso states, "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," said Richard Pattin, President of Calypso. "When others make use of our patented technology, we will continue to take aggressive action including the enforcement of our legal rights."
Representing Calypso is the Williams Kherkher Law Firm, with its principal offices in Houston, Texas.
