3M Innovative Properties Co. and 3M Korea Ltd. filed a patent
infringement lawsuit on June 19, 2015, in the Seoul Central District
Court against LMS Co. Ltd.
The suit alleges that certain LMS Co. Ltd. light management film package
products, including a light management film package product sold under
the product name of “XLAS,” infringe 3M’s Korean Patent No. 1,074,570
titled "Method for Stacking Surface Structured Optical Films."
3M’s microreplicated stacked prism films, including 3M Advanced
Structured Optical Composites (ASOC), are integrated into LCD displays.
The prism films direct light to enable a thinner and more
energy-efficient electronic display.
3M is committed to protecting its intellectual property and investments
in optical film technologies.
