Seven years after filing and eighteen months after receiving notice of its allowance by the U.S. Patent Office, LeisureTech Electronics, announced that they have received U.S. patent no. 7,181,023 for their A-BUS technology. LeisureTech, inventors of the popular multi-room audio solution, already holds patents for A-BUS in Europe, Australia, New Zealand, Canada and Mexico.

Andrew Goldfinch, founder of LeisureTech and co-inventor of A-BUS technology, commented, “This is very welcome news indeed and it certainly reaffirms our long-held belief that A-BUS is a truly compelling idea. Over the last seven years, LeisureTech and our partners have successfully marketed the many benefits of A-BUS technology throughout the world. Having the actual U.S. patent in hand will further strengthen the A-BUS platform as the standard for affordable multi-room audio.”

A-BUS is a unique, proven technology for multi-room audio that utilizes a single cat5 cable to carry signal, data, infrared, status and power. This ingenious approach places the amplifiers closer to the speakers, enabling superior sound quality, increased flexibility, simpler installation, consumer-friendly operation, energy savings and greater affordability.
