You will be given a passage, and your task is to generate a Yes/No question that is answerable based on the given passage.

Let me give you an example: Powdered sugar, also called confectioners' sugar, icing sugar, and icing cake, is a finely ground sugar produced by milling granulated sugar into a powdered state. It usually contains a small amount of anti-caking agent to prevent clumping and improve flow. Although most often produced in a factory, powdered sugar can also be made by processing ordinary granulated sugar in a coffee grinder, or by crushing it by hand in a mortar and pestle.
The answer to this example can be: is confectionary sugar the same as powdered sugar?
Here is why: The question is a yes/no question, and it is answerable based on the given passage.

More famously, Harley-Davidson attempted to register as a trademark the distinctive ``chug'' of a Harley-Davidson motorcycle engine. On February 1, 1994, the company filed its application with the following description: ``The mark consists of the exhaust sound of applicant's motorcycles, produced by V-twin, common crankpin motorcycle engines when the goods are in use.'' Nine of Harley-Davidson's competitors filed oppositions against the application, arguing that cruiser-style motorcycles of various brands use the same crankpin V-twin engine which produces the same sound. After six years of litigation, with no end in sight, in early 2000, Harley-Davidson withdrew their application.
Answer:
does harley davidson have a patent on their sound?
