A trademark is anything that you use to identify your products and services with your company, including your company name, product names, service names, logos, taglines, sounds, colors, domain names, and some things that the USPTO hasn’t yet encountered.
For example, since web publishers started syndicating content via blogs and feeds, favicons become important for visually branding that syndicated content.
In 2007, Clocktower Law filed the first favicon trademark application, and the first favicon trademark registered in 2008.
