Requirement for Applying Judicial Exception with Machine
Note:
Examiners must consider if a judicial exception is applied using a particular machine in Step 2A Prong Two and Step 2B of the Alice-Mayo framework.

When determining whether a claim integrates a judicial exception, into a practical application in Step 2A Prong Two and whether a claim recites significantly more than a judicial exception in Step 2B, examiners should consider whether the judicial exception is applied with, or by use of, a particular machine. "The machine-or-transformation test is a useful and important clue, and investigative tool” for determining whether a claim is patent eligible under § 101. Bilski v. Kappos, 561 U.S. 593, 604, 95 USPQ2d 1001, 1007 (2010).

General Purpose Computer Does Not Qualify as Particular Machine
Note:
A general purpose computer applying an abstract idea with conventional functions does not qualify as a particular machine for patent eligibility.

It is important to note that a general purpose computer that applies a judicial exception, such as an abstract idea, by use of conventional computer functions does not qualify as a particular machine. Ultramercial, Inc. v. Hulu, LLC, 772 F.3d 709, 716-17, 112 USPQ2d 1750, 1755-56 (Fed. Cir. 2014). See also TLI Communications LLC v. AV Automotive LLC, 823 F.3d 607, 613, 118 USPQ2d 1744, 1748 (Fed. Cir. 2016) (mere recitation of concrete or tangible components is not an inventive concept); Eon Corp. IP Holdings LLC v. AT&T Mobility LLC, 785 F.3d 616, 623, 114 USPQ2d 1711, 1715 (Fed. Cir. 2015) (noting that Alappat ’s rationale that an otherwise ineligible algorithm or software could be made patent-eligible by merely adding a generic computer to the claim was superseded by the Supreme Court’s Bilski and Alice Corp. decisions). If applicant amends a claim to add a generic computer or generic computer components and asserts that the claim recites significantly more because the generic computer is 'specially programmed' (as in Alappat, now considered superseded) or is a 'particular machine' (as in Bilski), the examiner should look at whether the added elements integrate the exception into a practical application or provide significantly more than the judicial exception. Merely adding a generic computer, generic computer components, or a programmed computer to perform generic computer functions does not automatically overcome an eligibility rejection. Alice Corp. Pty. Ltd. v. CLS Bank Int’l, 573 U.S. 208, 223-24, 110 USPQ2d 1976, 1983-84 (2014). See In re Alappat, 33 F.3d 1526, 1545, 31 USPQ2d 1545, 1558 (Fed.

Claim Eligibility Even Without M-or-T Test
Note:
If a claim passes the Alice/Mayo test, it is eligible for patent even if it fails the machine-or-transformation 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 machine-or-transformation test ("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 Fails Alice/Mayo Test Is Ineligible Regardless of M-or-T
Note:
If a claim fails the Alice/Mayo test by being directed to an exception at Step 2A and does not amount to significantly more than the exception in Step 2B, it is ineligible for patentability even if it passes the machine-or-transformation test.

All claims must be evaluated for eligibility using the two-part test from Alice/Mayo.

Machine-Or-Transformation Test Is Not Sufficient Alone
Note:
The rule states that satisfying the machine-or-transformation test alone is not enough to make a claim patent-eligible, as not all transformations or machine implementations add 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 machine-or-transformation test ("M-or-T test").

Machine Must Significantly More Than Exception
Note:
A machine must significantly more than integrate a judicial exception if it performs a method, otherwise it does not provide practical application or significantly more.

Integral use of a machine to achieve performance of a method may integrate the recited judicial exception into a practical application or provide significantly more, in contrast to where the machine is merely an object on which the method operates, which does not integrate the exception into a practical application or provide significantly more. See CyberSource v. Retail Decisions, 654 F.3d 1366, 1370, 99 USPQ2d 1690, 1694 (Fed. Cir. 2011) ("We are not persuaded by the appellant's argument that the claimed method is tied to a particular machine because it ‘would not be necessary or possible without the Internet.’… Regardless of whether "the Internet" can be viewed as a machine, it is clear that the Internet cannot perform the fraud detection steps of the claimed method"). For example, as described in MPEP § 2106.05(f), additional elements that invoke computers or other machinery merely as a tool to perform an existing process will generally not amount to significantly more than a judicial exception. See, e.g., Versata Development Group v. SAP America, 793 F.3d 1306, 1335, 115 USPQ2d 1681, 1702 (Fed. Cir. 2015) (explaining that in order for a machine to add significantly more, it must “play a significant part in permitting the claimed method to be performed, rather than function solely as an obvious mechanism for permitting a solution to be achieved more quickly”).

Requirement for Machine Integration to Provide Significantly More
Note:
The rule requires that a machine must play a significant role in performing the method steps to be considered significantly more than a judicial exception.

Machine-Or-Transformation Test Is a Useful Clue for §101 Eligibility
Note:
The machine-or-transformation test helps determine if a claim is patent eligible under §101 by identifying whether the judicial exception is applied with or by use of a particular machine.

When determining whether a claim integrates a judicial exception, into a practical application in Step 2A Prong Two and whether a claim recites significantly more than a judicial exception in Step 2B, examiners should consider whether the judicial exception is applied with, or by use of, a particular machine. "The machine-or-transformation test is a useful and important clue, and investigative tool” for determining whether a claim is patent eligible under § 101. Bilski v. Kappos, 561 U.S. 593, 604, 95 USPQ2d 1001, 1007 (2010).

Generic Computer Does Not Automatically Overcome Eligibility Rejection
Note:
Merely adding a generic computer to perform generic functions does not automatically make an otherwise ineligible claim patentable.

It is important to note that a general purpose computer that applies a judicial exception, such as an abstract idea, by use of conventional computer functions does not qualify as a particular machine. Ultramercial, Inc. v. Hulu, LLC, 772 F.3d 709, 716-17, 112 USPQ2d 1750, 1755-56 (Fed. Cir. 2014). See also TLI Communications LLC v. AV Automotive LLC, 823 F.3d 607, 613, 118 USPQ2d 1744, 1748 (Fed. Cir. 2016) (mere recitation of concrete or tangible components is not an inventive concept); Eon Corp. IP Holdings LLC v. AT&T Mobility LLC, 785 F.3d 616, 623, 114 USPQ2d 1711, 1715 (Fed. Cir. 2015) (noting that Alappat ’s rationale that an otherwise ineligible algorithm or software could be made patent-eligible by merely adding a generic computer to the claim was superseded by the Supreme Court’s Bilski and Alice Corp. decisions). If applicant amends a claim to add a generic computer or generic computer components and asserts that the claim recites significantly more because the generic computer is 'specially programmed' (as in Alappat, now considered superseded) or is a 'particular machine' (as in Bilski), the examiner should look at whether the added elements integrate the exception into a practical application or provide significantly more than the judicial exception. Merely adding a generic computer, generic computer components, or a programmed computer to perform generic computer functions does not automatically overcome an eligibility rejection. Alice Corp. Pty. Ltd. v. CLS Bank Int’l, 573 U.S. 208, 223-24, 110 USPQ2d 1976, 1983-84 (2014). See In re Alappat, 33 F.3d 1526, 1545, 31 USPQ2d 1545, 1558 (Fed. Cir. 1994); In re Bilski, 545 F.3d 943, 88 USPQ2d 1385 (Fed. Cir. 2008)

Requirement for Machine to Add Significantly More
Note:
A machine must play a significant part in performing the method, rather than just facilitating faster solution achievement, to integrate the recited judicial exception into a practical application or provide significantly more.

Integral use of a machine to achieve performance of a method may integrate the recited judicial exception into a practical application or provide significantly more, in contrast to where the machine is merely an object on which the method operates, which does not integrate the exception into a practical application or provide significantly more. See CyberSource v. Retail Decisions, 654 F.3d 1366, 1370, 99 USPQ2d 1690, 1694 (Fed. Cir. 2011) ("We are not persuaded by the appellant's argument that the claimed method is tied to a particular machine because it ‘would not be necessary or possible without the Internet.’… Regardless of whether "the Internet" can be viewed as a machine, it is clear that the Internet cannot perform the fraud detection steps of the claimed method"). For example, as described in MPEP § 2106.05(f), additional elements that invoke computers or other machinery merely as a tool to perform an existing process will generally not amount to significantly more than a judicial exception. See, e.g., Versata Development Group v. SAP America, 793 F.3d 1306, 1335, 115 USPQ2d 1681, 1702 (Fed. Cir. 2015) (explaining that in order for a machine to add significantly more, it must “play a significant part in permitting the claimed method to be performed, rather than function solely as an obvious mechanism for permitting a solution to be achieved more quickly”).
