Middletown energy conservation company Nxegen LLC is suing a North Carolina firm for allegedly infringeing on a patent Nxegen holds for smart grid technology, court papers show.
Nxegen sued Sensus USA in New Haven federal court on July 29, court papers say.
In the lawsuit, Nxegen asks the court to order Sensus to stop the infringement and pay Nxegen damages for use of its technology.
Officials at Nxegen and Sensus were not immediately available for comment on Friday afternoon.
The smart grid technology enables users to see how exactly they are using energy in their home and business, and then control that usage to save money.
Several utility companies including Norwich Public Utilities and Connecticut Light & Power are undertaking smart grid products.
Founded in 1998, Nxegen provides a variety of energy conservation and load management services, including smart meter technology.
