Claimed and prior art ranges must have meaningful difference for nonobviousness

Patent claims can recite a numerical range and a patent can be awarded based on the novelty and nonobviousness of the claimed range. Normally, compositions are claimed in this manner but other types of inventions can be defined in terms of a numerical range such as a length as well. In re: Brandt (Fed. Cir. March 27, 2018) explains that very small differences in the respective ranges can support an obviousness rejection unless the inventor shows a meaningful difference exists.
