Physical Object Requirement for Article
Note:
An article must be a particular physical object that can be specifically identified and cannot include purely mental processes.

An “article” includes a physical object or substance. The physical object or substance must be particular, meaning it can be specifically identified. “Transformation” of an article means that the “article” has changed to a different state or thing. Changing to a different state or thing usually means more than simply using an article or changing the location of an article. A new or different function or use can be evidence that an article has been transformed. Purely mental processes in which thoughts or human based actions are “changed” are not considered an eligible transformation. For data, mere “manipulation of basic mathematical constructs [i.e.,] the paradigmatic ‘abstract idea,’” has not been deemed a transformation. CyberSource v. Retail Decisions, 654 F.3d 1366, 1372 n.2, 99 USPQ2d 1690, 1695 n.2 (Fed. Cir. 2011) (quoting In re Warmerdam, 33 F.3d 1354, 1355, 1360, 31 USPQ2d 1754, 1755, 1759 (Fed. Cir. 1994)).

Article Must Be Specifically Identifiable
Note:
The physical object or substance in an article must be specifically identifiable to meet the particular transformation requirement.

An “article” includes a physical object or substance. The physical object or substance must be particular, meaning it can be specifically identified. “Transformation” of an article means that the “article” has changed to a different state or thing. Changing to a different state or thing usually means more than simply using an article or changing the location of an article. A new or different function or use can be evidence that an article has been transformed. Purely mental processes in which thoughts or human based actions are “changed” are not considered an eligible transformation. For data, mere “manipulation of basic mathematical constructs [i.e.,] the paradigmatic ‘abstract idea,’” has not been deemed a transformation. CyberSource v.

Transformation of Physical Object Means Change to Different State
Note:
This rule states that an article has undergone a transformation if it changes to a different state or thing, beyond simple use or location change.

An “article” includes a physical object or substance. The physical object or substance must be particular, meaning it can be specifically identified. “Transformation” of an article means that the “article” has changed to a different state or thing. Changing to a different state or thing usually means more than simply using an article or changing the location of an article. A new or different function or use can be evidence that an article has been transformed. Purely mental processes in which thoughts or human based actions are “changed” are not considered an eligible transformation. For data, mere “manipulation of basic mathematical constructs [i.e.,] the paradigmatic ‘abstract idea,’” has not been deemed a transformation. CyberSource v.

Transformation of Article Means More Than Location Change
Note:
The transformation of an article includes changes in state or function, not just location.

An “article” includes a physical object or substance. The physical object or substance must be particular, meaning it can be specifically identified. “Transformation” of an article means that the “article” has changed to a different state or thing. Changing to a different state or thing usually means more than simply using an article or changing the location of an article.

New Function Indicates Transformation
Note:
A change in an article's function can indicate that it has been transformed.

An “article” includes a physical object or substance. The physical object or substance must be particular, meaning it can be specifically identified. “Transformation” of an article means that the “article” has changed to a different state or thing. Changing to a different state or thing usually means more than simply using an article or changing the location of an article. A new or different function or use can be evidence that an article has been transformed.

Mental Processes Are Not Eligible Transformations
Note:
This rule states that purely mental processes, even if they change thoughts or actions, do not qualify as a transformation of an article for patent eligibility purposes.

An “article” includes a physical object or substance. The physical object or substance must be particular, meaning it can be specifically identified. “Transformation” of an article means that the “article” has changed to a different state or thing. Changing to a different state or thing usually means more than simply using an article or changing the location of an article.

Manipulating Data Is Not a Transformation
Note:
This rule states that merely manipulating basic mathematical constructs in data does not constitute a transformation for patent eligibility purposes.

An “article” includes a physical object or substance. The physical object or substance must be particular, meaning it can be specifically identified. “Transformation” of an article means that the “article” has changed to a different state or thing. Changing to a different state or thing usually means more than simply using an article or changing the location of an article.

Transformation of Physical Article Must Be Specific
Note:
The transformation must involve a change to a different state or function of a particular physical object, not just manipulation of data or thoughts.

An “article” includes a physical object or substance. The physical object or substance must be particular, meaning it can be specifically identified. “Transformation” of an article means that the “article” has changed to a different state or thing. Changing to a different state or thing usually means more than simply using an article or changing the location of an article.

Claim Eligibility If Alice/Mayo Test Passed
Note:
A claim is eligible for patent if it passes the Alice/Mayo test, even if it fails the M-or-T test.

All claims must be evaluated for eligibility using the two-part test from Alice/Mayo. If a claim passes the Alice/Mayo test (i.e., is not directed to an exception at Step 2A, or amounts to significantly more than any recited exception in Step 2B), then the claim is eligible even if it “fails” the M-or-T test. Bilski v. Kappos, 561 U.S. 593, 604, 95 USPQ2d 1001, 1007 (2010) (explaining that a claim may be eligible even if it does not satisfy the M-or-T test); McRO, Inc. v. Bandai Namco Games Am. Inc., 837 F.3d 1299, 1315, 120 USPQ2d 1091, 1102 (Fed. Cir. 2016) (“[T]here is nothing that requires a method ‘be tied to a machine or transform an article’ to be patentable”). And if a claim fails the Alice/Mayo test (i.e., is directed to an exception at Step 2A and does not amount to significantly more than the exception in Step 2B), then the claim is ineligible even if it passes the M-or-T test. DDR Holdings, LLC v. Hotels.com, L.P., 773 F.3d 1245, 1256, 113 USPQ2d 1097, 1104 (Fed. Cir. 2014) (“[I]n Mayo, the Supreme Court emphasized that satisfying the machine-or-transformation test, by itself, is not sufficient to render a claim patent-eligible, as not all transformations or machine implementations infuse an otherwise ineligible claim with an “inventive concept.”).

Claim Is Ineligible If Fails Alice/Mayo Test
Note:
A claim is ineligible for patentability if it fails the Alice/Mayo test, even if it meets other requirements like the M-or-T test.

All claims must be evaluated for eligibility using the two-part test from Alice/Mayo. If a claim passes the Alice/Mayo test (i.e., is not directed to an exception at Step 2A, or amounts to significantly more than any recited exception in Step 2B), then the claim is eligible even if it “fails” the M-or-T test. Bilski v. Kappos, 561 U.S. 593, 604, 95 USPQ2d 1001, 1007 (2010) (explaining that a claim may be eligible even if it does not satisfy the M-or-T test); McRO, Inc. v. Bandai Namco Games Am.

Machine-Or-Transformation Test Not Sufficient For Eligibility
Note:
The machine-or-transformation test alone is not enough to make a claim patent-eligible; it must also include an inventive concept.

All claims must be evaluated for eligibility using the two-part test from Alice/Mayo. If a claim passes the Alice/Mayo test (i.e., is not directed to an exception at Step 2A, or amounts to significantly more than any recited exception in Step 2B), then the claim is eligible even if it “fails” the M-or-T test.
