Do I need to trademark my logo?

It depends on whether you feel that your logo helps you grow and distinguish your business from the competition.  Keep in mind that if a large corporation federally trademarks "your" logo, they might force you to abandon it.  If you plan on franchising your business or compete nationally/globally (e.g., websites doing interstate commerce), then trademarking is something you need to seriously consider. If you like the logo design and believe it has the necessary qualities to stay with your business for years, trademark it! Starbucks® trademarked their logo early on when they were local and small.  The branding of your company is a crucial element to the success of your company.
