Answer:
a. protect "distinctive" or "famous" marks from unauthorized uses even when confusion is not likely to occur.
Step-by-step explanation:
Trademark dilution laws are rules and regulations that seek to protect the trademarks of well known brands from unauthorized use by other brands, in such a way that the distinctive attribute of the trademark is minimized. Trademark dilution laws are meant to ensure that the main purpose for which a product's trademark is known is meant to stand out significantly in the mind of consumers.
Smaller companies might want to copy the trademark of famous brands for their products which might be different. These laws seek to prevent this act even if it may not cause confusion in the minds of consumers as to which brand owns a product.
