No, human organisms are not patentable subject matter. The Leahy-Smith America Invents Act (AIA) explicitly excludes claims directed to or encompassing a human organism from patentability.

Section 33(a) of the AIA states: “Notwithstanding any other provision of law, no patent may issue on a claim directed to or encompassing a human organism.”

This provision codifies existing USPTO policy that human organisms are not patent-eligible subject matter. If the broadest reasonable interpretation of a claimed invention encompasses a human organism, it must be rejected under 35 U.S.C. 101 and AIA sec. 33(a).
