Chapter 900 : 13 Paragraph 5 of Compendium Of U.S. Copyright Office Practises Third Edition states:
"Typeface ornamentation that is separable from the typeface characters is almost always an add-on to the beginning and/or ending of the characters. To the extent that such flourishes, swirls, vector ornaments, scrollwork, borders and frames, wreaths, and the like represent works of pictorial or graphic authorship in either their individual designs or patterned repetitions, they may be protected by copyright. However, the mere use of text effects (including chalk, popup papercraft, neon, beer glass, spooky-fog, and weathered-and-worn), while potentially separable, is de minimis and not sufficient to support a registration."
