Genericized Trademark: A trademark that has become so widely used to refer to a product category that it has lost its ability to uniquely identify a specific brand, often resulting in the trademark becoming a generic term.
Fair Use:A legal doctrine that allows the use of copyrighted material without permission from the copyright holder for certain purposes, such as commentary, criticism, news reporting, teaching, or research.
Trademark Dilution:A reduction in the distinctiveness of a trademark, often caused by the widespread use of the mark to refer to a product category rather than a specific brand.
