1202.17(e)(vi) Universal Prohibition Symbol 
The universal prohibition symbol, which usually appears superimposed over another image or wording, is a visual representation of "no," "not," or "prohibited." See, e.g., Free Signage.com, Prohibition Signs, http://www.freesignage.com/prohibited_signs.php (accessed June 16, 2021). When the prohibition symbol is superimposed over other matter, the design as a whole is unitary; thus, no disclaimer of the prohibition symbol apart from the other matter is necessary. However, the examining attorney must consider whether evidence supports the conclusion that the design as a whole (i.e., the symbol and the image it is superimposed over) fails to function as a mark or is merely descriptive (or both) and thus must be refused or disclaimed.
