Samsung's Galaxy S 4 isn't even available yet, but already it's being eyed for possible patent infringement. According to a report from Korea's Yonhap News, LG suspects the S 4 might violate eye-tracking patents used in the Optimus G Pro. At the crux of this squabble is Samsung's Smart Pause feature, which LG finds similar to its Smart Video technology. Chiefly, LG is focusing on a patent it applied for in 2009, though the company also plans to investigate whether Samsung infringed other eye-tracking patents dating back to 2005. So far, of course, Samsung has denied any wrongdoing, saying its eye-tracking tech is implemented differently and is based on proprietary technology. Given that the phone isn't even out yet, we'll leave it to LG to do its due diligence before accusing Samsung in court.
