TransData files patent infringement suits against General Electric and Landis & Gyr
September 24, 2015
TransData has filed smart meter patent infringement lawsuits against General Electric and Landis & Gyr over digital electric meters equipped with an internal under-glass wireless communications circuit and antenna.
The Texas-based developer and manufacturer of digital electricity meters and related energy measurement products for the electric utility industry filed the lawsuits in the US District Court for the Eastern District of Texas.
In the lawsuits, TransData asserts that General Electric, Itron and Landis & Gyr are wilfully infringing TransData's US smart meter patents 6,181,294, 6,462,713 and 6,903,699 by making, using, selling, and/or offering for sale in the USA, or importing into the USA, various electric meters equipped with an internal under-glass wireless communications circuit and antenna.
The smart meter patents relate to the company's development of the first digital electric meter to be equipped with an internal under-glass wireless communications circuit and antenna. Current licensees of TransData's smart meter patents include Sensus USA, Sensus Metering, Southern Company, Alabama Power, Georgia Power, Mississippi Power, Gulf Power, M2M Technologies and Telensa.
Five years ago, TransData instituted litigation over these same patents against several electric utilities, including Oncor Electric Delivery (an Energy Future Holdings company), CenterPoint Energy, Texas-New Mexico Power, Oklahoma Gas & Electric, San Diego Gas & Electric, CoServ Electric, Denton Municipal Electric and Tri-County Electric Cooperative. These electric utility cases are currently on-going and are proceeding towards trial.
As a result of the electric utility litigations, TransData's smart meter patents have been subjected to 13 validity challenges at the US Patent & Trademark Office, including four challenges filed by Itron and nine by General Electric. In each instance, the Patent Office reconfirmed the validity of all claims in TransData's smart meter patents.
In business for 46 years, TransData specialises in the design and manufacture of solid-state electric meters and related products that enable its global client base to measure, monitor and control the flow of power and energy variables on the smart grid. Founded in 1969, TransData is a privately held corporation with headquarters in suburban Dallas, serving over 2000 customers in more than 25 countries worldwide, including all of the top 50 largest US electric utilities.
Landis & Gyr is 60 per cent owned by Toshiba and 40 per cent by Innovation Network of Japan, a public-private partnership between the Japanese government and more than 25 individual corporations. Last week, it received the 2014 AMI Company of the Year Award at the Frost & Sullivan Growth, Innovation & Leadership Awards Gala in Santa Clara, California.
