Question: In 1572, during the reign of Queen Elizabeth I of England, a patent application was filed for a knife with a bone handle rather than a wooden one. Would this patent be granted under current U.S. law? Strategy: Was a bone handle novel, nonobvious, and useful? Result: It was useful-no splinters from a bone handle. It was novel-no one had ever done it before. But the patent was denied because it was obvious.
