U.S. patent law Edit

The Markush doctrine refers to a situation where the materials recited in a claim are so related as to constitute claiming the members of the claimed group in the alternative, such as "selected from the group consisting of A, B and C." The members of a Markush group must have at least one property that is mainly responsible for their membership in the group.[1]
