Based on it, or just an independently invented similar idea? The latter is common throughout history. Consider the "ship camel" invented in Holland in 1690 and patented by Abraham Lincoln in 1849. Or frequency modulation, invented in 1919 by Hanso Idzerda, then reinvented around 1930 by Edwin Armstrong (both got patents; the later patent does not refer to the earlier one as prior art).
