Sony sues Fujifilm on 3M-acquired patents

Sony Corporation recently filed a patent infringement lawsuit in U.S. District Court for the Southern District of Florida against Japanese photography and imaging company Fujifilm. At the center of Sony’s legal action are magnetic tape products marketed by Fujifilm which allegedly practice technology copied from Sony without a license.

In the official complaint filed by Sony, the company asserts a series of four patents, which it alleges Fujifilm infringed through the sale of the company’s Linear Tape-Open (LTO) format magnetic tapes, specifically generation four, five and six LTO tapes (LTO-4, LTO-5, LTO-6).
