On September 11, 2015, TransData filed three separate complaints in federal court in Tyler, Texas.
Each of the three complaints corresponds to a different defendant(s) (see the complaints here, here, and here), but each complaint assertsÂ the same three patents.Â These complaints follow a long list of consolidated â€œsmart meterâ€ cases, and in each complaint, Transdata notes that the defendant(s) indemnified and/or defended other defendant(s) in the earlier consolidated cases.
Two of the asserted patents, U.S. Patent Nos. 6,181,294Â (‘294 Patent)and 6,462,713Â (‘713 Patent) are related and entitled â€œAntenna for Electric Meter and Manufacture Thereof.â€Â The third patent, U.S. Patent No. 6,903,699, entitled â€œWireless Communication Device for Electric Meter and Method of Manufacture Thereof,â€ is a continuation-in-part of â€˜713 and continuation of â€˜294.
These patents describe an electric meter capable of bi-directional communication over a wireless network.Â The meter is equipped with wireless communication circuitry and an antenna allowing the meter to wirelessly send usage data to a remote location and wirelessly, receive operational instructions from the remote location.
