35 U.S.C. 103   Conditions for patentability; non-obvious subject matter.

    • (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102  of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made.
    • (b)
      • (1) Notwithstanding subsection (a), and upon timely election by the applicant for patent to proceed under this subsection, a biotechnological process using or resulting in a composition of matter that is novel under section 102  and nonobvious under subsection (a) of this section shall be considered nonobvious if-
        • (A) claims to the process and the composition of matter are contained in either the same application for patent or in separate applications having the same effective filing date; and
        • (B) the composition of matter, and the process at the time it was invented, were owned by the same person or subject to an obligation of assignment to the same person.
      • (2) A patent issued on a process under paragraph (1)-
        • (A) shall also contain the claims to the composition of matter used in or made by that process, or
        • (B) shall, if such composition of matter is claimed in another patent, be set to expire on the same date as such other patent, notwithstanding section 154.
      • (3) For purposes of paragraph (1), the term "biotechnological process" means-
        • (A) a process of genetically altering or otherwise inducing a single- or multi-celled organism to-
          • (i) express an exogenous nucleotide sequence,
          • (ii) inhibit, eliminate, augment, or alter expression of an endogenous nucleotide sequence, or
          • (iii) express a specific physiological characteristic not naturally associated with said organism;
        • (B) cell fusion procedures yielding a cell line that expresses a specific protein, such as a monoclonal antibody; and
        • (C) a method of using a product produced by a process defined by subparagraph (A) or (B), or a combination of subparagraphs (A) and (B).
    • (c)
      • (1) Subject matter developed by another person, which qualifies as prior art only under one or more of subsections (e), (f), and (g) of section 102  of this title, shall not preclude patentability under this section where the subject matter and the claimed invention were, at the time the claimed invention was made, owned by the same person or subject to an obligation of assignment to the same person.
      • (2) For purposes of this subsection, subject matter developed by another person and a claimed invention shall be deemed to have been owned by the same person or subject to an obligation of assignment to the same person if —
        • (A) the claimed invention was made by or on behalf of parties to a joint research agreement that was in effect on or before the date the claimed invention was made;
        • (B) the claimed invention was made as a result of activities undertaken within the scope of the joint research agreement; and
        • (C) the application for patent for the claimed invention discloses or is amended to disclose the names of the parties to the joint research agreement.
      • (3) For purposes of paragraph (2), the term "joint research agreement" means a written contract, grant, or cooperative agreement entered into by two or more persons or entities for the performance of experimental, developmental, or research work in the field of the claimed invention.

Leahy-Smith America Invents Act, Public Law 112-29, sec. 14, 125 Stat. 284 provides as follows:

    • (a) IN GENERAL.—For purposes of evaluating an invention under section 102 or 103 of title 35, United States Code, any strategy for reducing, avoiding, or deferring tax liability, whether known or unknown at the time of the invention or application for patent, shall be deemed insufficient to differentiate a claimed invention from the prior art.

      • (1) is a method, apparatus, technology, computer program product, or system, that is used solely for preparing a tax or information return or other tax filing, including one that records, transmits, transfers, or organizes data related to such filing; or
      • (2) is a method, apparatus, technology, computer program product, or system used solely for financial management, to the extent that it is severable from any tax strategy or does not limit the use of any tax strategy by any taxpayer or tax advisor.
    • (d) RULE OF CONSTRUCTION.—Nothing in this section shall be construed to imply that other business methods are patentable or that other business method patents are valid.
    • (e) EFFECTIVE DATE; APPLICABILITY.—This section shall take effect on the date of the enactment of this Act [Sept. 16, 2011] and shall apply to any patent application that is pending on, or filed on or after, that date, and to any patent that is issued on or after that date.]
