Transdata protects smart meter patents

TransData protects smart meter patentsIn the US, Texas-based meter manufacturer TransData announced last week that it had received a notification from the US Patent and Trademark Office stipulating that General Electric’s requests for re-examination of its smart electric meter patent portfolio had been denied.

The Inter Parties Review (IPR), submitted by GE, attempted to challenge the validity of TransData’s smart meter patent portfolio, stated a company release.

The three TransData smart meter patents under review (US Patents 6,181,29; 6,462,713 and 6,903,699) have undergone a total of 10 patent re-examination tests at the US Patent Office with all of TransData technology claims remaining valid.

The three patents relate to TransData’s development of the “first digital electric meter equipped with an internal 'under-glass' wireless communication module and antenna”. This technology is said to be key to enabling the electric meter circuitry witin the digital electric meter to communicate wirelessly.

Holders and licencees of TransData’s smart meter patent portfolio include Sensus USA, Sensus Metering, M2M Technologies and Telensa.

Trace Gleibs, president of TransData, said: “We are disappointed that General Electric and the other indemnifying meter manufacturers have refused to recognize the validity of our patents and accept liability for patent infringement despite the fact that all of the final determinations issued by Patent Office have been in TransData’s favour.

“We will continue to stand vigilant in protecting our intellectual property.”

TransData files suits against infringement

TransData has filed patent infringement lawsuits against a number of US utilities including Oklahoma Gas & Electric, Oncor Electric Delivery, and Centerpoint Energy for the “making, using, offering to sell, selling, and/or importing certain digital electric meters equipped with an internal wireless communication circuit and antenna that infringe TransData's Patents”, according to previous company statement.

Through a public filing, GE has confirmed that it would defend Oklahoma Gas & Electric, Oncor Electric Delivery, and Centerpoint Energy against TransData's claims.

In October last year, TransData licensed its wireless smart electric meter patents to Telensa.

Mr Gleibs, president of TransData, said: “We also appreciate the fact that Telensa recognized the significant value our patents provide and voluntarily approached TransData to license our patents."

TransData's counsel, Jamie McDole of Haynes & Boone, LLP, added: "With so many large companies recklessly infringing upon TransData's patent rights, I am pleased that Telensa took the less litigious route and affirmatively requested a license before utilizing TransData's patented technology."
