The company’s US patent numbers which were licensed include 6,181,294; 6,462,713; and 6,903,699.

Both the firms did not disclose the financial terms of the transaction.

The deal marks TransData’s fourth license agreement signed under its Smart Meter Patent portfolio.

The company’s covers technology which it first invented and implemented in the mid-1990s.

TransData said its smart meter patents are directed towards equipping a digital electric meter with an internal under-glass wireless communication circuit and antenna that allows the electric meter circuitry within the meter to communicate wirelessly.

TransData president Trace Gleibs said the agreement further demonstrates the significance of the technology to the manufacture and operation of wirelessly communicating smart electric meters.

"We are extremely pleased to have signed yet another license agreement for our Smart Meter Patents, and appreciate the fact that M2M Engineering voluntarily approached TransData to license our patents," Gleibs said.
