Dallas-based TransData has seen off another smart meter patent challenge by General Electric. The US Patent Office concluded an ex parte re-examination of the 294 Patent and will issue a re-examination certificate that reaffirms validity of all pending claims.
This decision marks another victory by TransData over the serial patent re-examinations being filed against the company's smart meter patents by General Electric. The 294 patent has now withstood several patent re-examinations filed by General Electric and another smart meter manufacturer.
TransData's development of the industry's first digital electric meter equipped with an internal under-glass wireless communications module and antenna resulted in the company being awarded several US patents, including the 294 Patent. The invention lets users wirelessly access the data available from within a digital electric meter, including meter billing information, interval usage data, voltage levels, power outage and power quality information.
The 294 patent is the subject matter of patent infringement lawsuits TransData filed against a group of electric utilities involving millions of digital electric meters equipped with internal wireless communications that are commonly referred to as smart meters. The case is currently pending before the US District Court for the Western District of Oklahoma and includes as defendants Oklahoma Gas & Electric, Oncor Electric Delivery, CenterPoint Energy, San Diego Gas & Electric, Texas-New Mexico Power, Denton County Electric, Denton Municipal Utilities, and Tri-County Electric Cooperative.
"We appreciate the hard work and effort of the multitude of patent examiners who have reviewed and confirmed the validity of our patents," said Joan Gleibs, TransData, CEO. "We believe our patents are even stronger now that they have been reviewed and confirmed by numerous Patent Office experts with knowledge of the relevant technology and patent law."
The company has an established licensing programme for its smart meter patents, which includes investor-owned utilities and companies active in the manufacture of digital electric meters, wireless smart-meter communications modules and wireless streetlight control systems.
