Motorola sued over wireless power transfer tech in smartphones

Complaint against Lenovo subsidiary follows suits against Samsung and Google Electronic | Edison Transmission Technologies seeks to assert power transfer patents.

Motorola is the latest smartphone manufacturer to be hit with a lawsuit over wireless power transfer technology, after Electronic Edison Transmission Technologies (EETT) filed a complaint for patent infringement against the Lenovo subsidiary in Texas.

EETT, an entity associated with inventor and plaintiff Leigh Rothschild, told the US District Court for the Eastern District of Texas on Friday, May 31, that Motorola had infringed a patent it owned—US patent number 9,448,603.

The ‘603 patent is entitled ‘Transferring Power to a Mobile Device’, and according to the complaint, teaches systems and methods for wirelessly transferring power to a receptor mobile device from a donor mobile device.

EETT alleged that Motorola had infringed its patent through the sale of products including the Motorola Edge+, Motorola Edge 40 and Motorola Razr+, which it said implemented Qi, a standard for wireless power transfer functionality.

The company asked the Texas court for damages and an order preventing Motorola from infringing the ‘603 patent and two others in the patent family—US patents 9,871,415, and 10,454,305.

Patent family litigation

EETT’s patent infringement suit against Motorola follows complaints against Samsung in February this year, and Google in May.

In separate lawsuits, the company sought to assert the ‘603 patent against Google, and the ‘603, ‘415 and ‘305 patents against Samsung.

EETT claimed that Samsung had infringed its wireless power transfer patents through the sale of products including Galaxy smartwatches and Galaxy Z fold phones that comprised a ‘wireless power share’ or ‘reverse charging’ feature and were compliant with Qi.

In the suit against Google, EETT named a number of Pixel products as allegedly infringing devices that used the technology.

Rothschild is reportedly listed as the sole inventor of more than 130 patents and monetises his IP through litigation and licensing.

In Electronic Edison Transmission Technologies v Motorola Solutions, EETT is represented by Garteiser Honea and Sinergia Technology Law Group.
