	A '''patent interval''' of a (usually but not necessarily just) interval in a given [[edo]] is the number of edo steps of the best approximation of an interval in that edo. It's calculated by [[rounding]] the product of [[Wikipedia: binary logarithm\| binary logarithm]] (''log2'') of the interval ratio (''r'') and the edo number (''nEdo'').
