Trademark Infringement:Trademark infringement occurs when one party uses a trademark that is identical or confusingly similar to a trademark owned by another party, without the owner's permission, in a way that is likely to cause consumer confusion.
Likelihood of Confusion:The legal standard for determining trademark infringement, which evaluates whether the use of a mark is likely to cause consumers to be confused about the source or sponsorship of a product or service.
Dilution:The weakening of a trademark's distinctive quality and ability to identify the source of a product or service, which can occur through either blurring (the mark becoming less distinctive) or tarnishment (the mark becoming associated with negative qualities).
