Proper use is important when the trademark or service mark is used in product headings or titles, such as in website drop-down menus and Amazon ® product titles, and in any text, reference, or descriptions of the branded product or service, such as advertising copy, promotions, product/service category listings, product/service feature descriptions, user and how-to manuals, product packaging, and other textual references.

In general, you may use a third party’s mark without their authorization if you are referring to the third party or their products or services in a truthful manner. You may not use the mark in a way that mistakenly suggests affiliation with, or sponsorship or endorsement by, the trademark owner.
