1. US7280649B1

• Full Citation: US7280649B1, "System and method for providing services based on real time data communications for callers and called parties of a telecommunication call"
• Publication Date: October 9, 2007 (Filing date: February 13, 2004)
• Brief Description: This patent describes a system that provides various services, such as enhanced caller ID, multimedia advertisements, and product information, by establishing a data communication link parallel to a voice communication link during a telephone call.
