It is a common misconception that applying for trademark protection for a logo (referred to as a stylized mark) also provides full protection for any text contained in the logo. While there is some protection for the text contained in a logo, there are some limitations. 

An application for a stylized trademark provides protection for the design elements as well as any text in the exact format and arrangement that they are applied for. Variations in stylization generally require separate applications. 

An application for a word mark (referred to as a standard character mark), protects the words regardless of stylization, i.e., protection of the words exists in any font, colors, and with any additional design elements. This is helpful when it comes to enforcement against the use of similar text with a different stylization. Registration for a word mark provides broader protection for text than a related stylized mark would. 

Because of the broader scope of protection provided by a word mark, the majority of the time, a word mark may be a priority in terms of obtaining protection. However, if applying for more than one mark is within the budget, many logos have unique stylizations that surely warrant protection as soon as possible to secure exclusive rights over the design elements of the mark in addition to the text.
