This package covers both word mark and design mark or logo of your word mark. Logo is typically used on letterheads, product packaging, marketing, company webpages etc. They are important source of brand recognition. It would be a good strategy to get USPTO federal trademark protection for both word mark and logo at the same time. Alternatively, you can also use this form to order registration of word mark and designs (such as stylized marks, color use etc.) other than logo.
