PRNewswire: Viavi Solutions files a patent infringement complaint with the U.S. International Trade Commission ("ITC") to initiate an investigation against LG Electronics, LG Electronics U.S.A., LG Innotek, and Optrontec.

VIAVI is a pioneer in the field of 3D motion sensing technology, including VIAVI's optical filters. In a typical gesture-recognition system, a light source emits near-infrared light towards a user and an optical filter is used to transmit the emitted light that is reflected by the user to a 3D image sensor, while substantially blocking ambient light. The patented VIAVI optical filters achieve superior optical performance, a desired reduction in filter thickness, and a reduced center wavelength shift with a change in incidence angle of the reflected light.

Mobile device manufacturers like LG Electronics, and its suppliers including LG Innotek and Optrontec, have incorporated VIAVI's patented optical filter design into their optical filters and components to produce high-end mobile phones and tablet computers featuring facial and gesture recognition technology. In the ITC, VIAVI seeks relief, including an exclusion order preventing Defendants from importing the infringing electronic devices into the United States. In the California litigation, VIAVI seeks damages and injunctive relief, including a permanent injunction prohibiting Defendants from importing the infringing electronic devices into the United States.
