Arbitrary Trademark: An arbitrary trademark is a word or symbol that has no inherent connection to the product or service it represents, such as 'Apple' for computers or 'Dove' for soap.
Suggestive Trademark: A suggestive trademark implies a characteristic or quality of the product or service without directly describing it, such as 'Greyhound' for a bus company or 'Citibank' for a financial institution.
Fanciful Trademark: A fanciful trademark is a made-up word or symbol that has no meaning outside of the brand, such as 'Xerox' for photocopiers or 'Kodak' for cameras.
