Use Of Company Logo Agreement
Competitors and individuals do not require written authorization for the use of a logo if the use is based on the following reasons: U.S. law prohibits the use of government logos without written authorization. Although some logos are not protected by copyright, they remain protected by trademark laws. For example, you cannot use the Central Intelligence Agency logo without authorization to prevent the CIA from supporting your work or your point of view. As long as the work of fiction does not leave the viewer perplexed as to who owns the mark, the use of logos in fiction falls into fair use, because it increases the realism of a story.
