AIA vs Pre-AIA Practice
Note:
This rule outlines the differences in practice for applications subject to AIA and pre-AIA laws, specifically regarding the relevant time frame for prior art considerations.

[Editor Note: This MPEP section is applicable regardless of whether an application is examined under the AIA or under pre-AIA law. For applications subject to the first inventor to file (FITF) provisions of the AIA, the relevant time is “before the effective filing date of the claimed invention”. For applications subject to pre-AIA 35 U.S.C. 102, the relevant time is “at the time of the invention”. See MPEP § 2150 et seq. Many of the court decisions discussed in this section involved applications or patents subject to pre-AIA 35 U.S.C. 102. These court decisions may be applicable to applications and patents subject to AIA 35 U.S.C. 102 but the relevant time is before the effective filing date of the claimed invention and not at the time of the invention.]

Inventions Suitable for Tax-Favored Structures Must Meet Certain Requirements
Note:
Inventions designed for use with tax-favored structures like employee benefit plans and tax-exempt organizations must comply with specific requirements as defined by AIA section 14.

The following procedure should be followed when examining claims relating to tax strategies.
3. Identify any limitations relating to a tax strategy, as defined above (note the listed exclusions). a. Inventions that fall within the scope of AIA section 14 include those tax strategies especially suitable for use with tax-favored structures that must meet certain requirements, such as employee benefit plans, tax-exempt organizations, or other entities that must be structured or operated in a particular manner to obtain certain tax consequences.

AIA Section 14 Applies to Tax Strategies
Note:
This rule states that AIA section 14 applies when an invention aids in satisfying tax-favored entity requirements, taking advantage of specific tax benefits, or reducing taxes not automatically available.

The following procedure should be followed when examining claims relating to tax strategies.
3. Identify any limitations relating to a tax strategy, as defined above (note the listed exclusions). b. Thus, AIA section 14 applies if the effect of an invention is to aid in satisfying the qualification requirements for a desired tax-favored entity status, to take advantage of the specific tax benefits offered in a tax-favored structure, or to allow for tax reduction, avoidance, or deferral not otherwise automatically available in such entity or structure.

Tax Strategies Deemed Part of Prior Art Under AIA
Note:
For novelty and nonobviousness evaluations, any tax strategy is considered part of the prior art regardless of its known status.

The Leahy-Smith America Invents Act (AIA), Public Law 112-29, sec. 14, 125 Stat. 284 (September 16, 2011) provides that for purposes of evaluating an invention for novelty and nonobviousness under 35 U.S.C. 102 and 35 U.S.C. 103, any strategy for reducing, avoiding, or deferring tax liability (hereinafter “tax strategy”), whether known or unknown at the relevant time, shall be deemed insufficient to differentiate a claimed invention from the prior art. As a result, applicants will no longer be able to rely on the novelty or non-obviousness of a tax strategy embodied in their claims to distinguish them from the prior art. Any tax strategy will be considered indistinguishable from all other publicly available information that is relevant to a patent’s claim of originality. This provision aims to keep the ability to interpret the tax law and to implement such interpretation in the public domain, available to all taxpayers and their advisors.

Examination Procedure for Tax Strategies
Note:
Follow specific steps to examine claims related to tax strategies, construing the claim and analyzing compliance with patent laws.
The following procedure should be followed when examining claims relating to tax strategies.
  • 1. Construe the claim in accordance with MPEP § 2111 et seq.
  • 2. Analyze the claim for compliance with 35 U.S.C. 101 and 112 in accordance with current guidance, which is unaffected by this provision.
  • 3. Identify any limitations relating to a tax strategy, as defined above (note the listed exclusions).
    • a. Inventions that fall within the scope of AIA section 14 include those tax strategies especially suitable for use with tax-favored structures that must meet certain requirements, such as employee benefit plans, tax-exempt organizations, or other entities that must be structured or operated in a particular manner to obtain certain tax consequences.
    • b. Thus, AIA section 14 applies if the effect of an invention is to aid in satisfying the qualification requirements for a desired tax-favored entity status, to take advantage of the specific tax benefits offered in a tax-favored structure, or to allow for tax reduction, avoidance, or deferral not otherwise automatically available in such entity or structure.
  • 4. Evaluate the claim in view of the prior art under 35 U.S.C. 102 and 103, treating any limitations relating to a tax strategy as being within the prior art, and not as a patentable difference between the claim and the prior art. This approach is analogous to the treatment of printed matter limitations in a claim as discussed at MPEP § 2112.01, subsection III.

Claim Limitations for Tax Return Software
Note:
For software inventions, claim limitations enabling tax return filing or financial management are patentable unless they involve a tax strategy.

Thus, for purposes of applying art to a software-related invention under 35 U.S.C. 102 and 35 U.S.C. 103, claim limitations that are directed solely to enabling individuals to file their income tax returns or assisting them with managing their finances should be given patentable weight, except that claim limitations directed to a tax strategy should not be given patentable weight.
