Design patents cover the “ornamental look” of an object. A protectable design includes characteristics that are unique to the look of a product. Sometimes the utility of an object (i.e. a knife) may not be patentable, however the look of the object may be distinct enough to warrant protection. Typically, inventors want to protect functionality of an object, but sometimes object (i.e. gaming systems in this blog post) can look interesting enough to warrant protection.
