On April 15, 2008, the United States Patent Office granted me U.S. Patent #7,360,234: "System, Method, and computer program product for selective filtering of objectionable content from a program."
I developed this system for a company called CaptionTV. Current V-Chip technology either allows a show to be watched, or blocks it completely. My filtering technology allows a television show to be watched with only specific types and levels of objectionable content blocked, thus allowing a family with young children to still watch a PG or R-rated show.
