Office Action

§101
DETAILED ACTION Status of Application This action is a Final Rejection. This action is in response to the amendment and response filed on January 30, 2026. Claims 1-14, 20, and 22-34 have been canceled. Claims 35-48 have been added. Claims 15 and 21 have been amended. Claims 15-19, 21, and 35-48 are rejected. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Response to Arguments Regarding the rejection under 35 U.S.C. § 101, Applicant argues the claims are eligible for reasons presented in the interview. Remarks at 12. However, agreement on this rejection was not reached during the interview. The claims are ineligible for the reasons given in the rejection below. Therefore, the rejection has been maintained. Regarding the rejection under 35 U.S.C. § 103, the rejection is withdrawn in light of Applicant’s amendments and remarks. The particular combination of limitations recited in each independent claim, including, for example, the limitation of transmitting both the first token and the persistent identifier to the registered device (within the context of the full claim), makes the claims nonobvious and novel. Claim Objections Claims 15, 36, and 43 are objected to for the following reason: Claim 15 recites “generate, for an account, a persistent identifier, wherein the persistent identifier is a digital identifier that remains constant across multiple responses associated with an account, irrespective of variations in account tokenization by a data provider, and wherein each token is mapped to the persistent identifier and stored.” Claims 36 and 43 recite similar limitations. These limitations refer to “each token.” However, no tokens have previously been referenced. Therefore, there is a lack of antecedent basis for “each token.” Appropriate correction is required. Claim 15 is objected to for the following reason: Claim 15 recites “generate a first token based on the account information, wherein the first token expires after a single use for the first event.” The portion of the limitation in bold was removed from the other independent claims and it conflicts with claim 35. It appears that Applicant likely intended to delete this portion of the limitation. Appropriate correction is required. Claim Rejections - 35 USC § 101 35 U.S.C. § 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 15-19, 21, and 35-48 are rejected under 35 U.S.C. § 101 as being directed to non-statutory subject matter because the claimed invention is directed to an abstract idea without significantly more. Step 1: Does the Claim Fall within a Statutory Category? (see MPEP 2106.03) Yes, with respect to claims 15-19, 21, and 35 which recite a non-transitory computer-readable medium and, therefore, are directed to the statutory class of manufacture. Yes, with respect to claims 36-42, which recite a device comprising one or more processors and, therefore, are directed to the statutory class of machine or manufacture. Yes, with respect to claims 43-48, which recite a method and, therefore, are directed to the statutory class of process. Step 2A, Prong One: Is a Judicial Exception Recited? (see MPEP 2106.04(a)) The following claims (Claims 15-19, 21, and 35 are representative) identify the limitations that recite the abstract idea in regular text and that recite additional elements in bold: 15. A non-transitory computer-readable medium storing a set of instructions comprising: one or more instructions that, when executed by one or more processors of a device, cause the device to: generate, for an account, a persistent identifier, wherein the persistent identifier is a digital identifier that remains constant across multiple responses associated with an account, irrespective of variations in account tokenization by a data provider, and wherein each token is mapped to the persistent identifier and stored; receive, over a network associated with financial data and from a registered device, a first authorization request for account information of the account to use for a first event; generate a first token based on the account information, wherein the first token expires after a single use for the first event; wherein the first token is a digital token used in one or more transactions over the network until an expiration of the first event; transmit, as a first response of the multiple responses and in response to the first authorization request, the first token and the persistent identifier to the registered device; receive, from the registered device, a second authorization request for the account information to use for a second event; generate a second token based on the account information, wherein the second token is used in one or more transactions over the network until an expiration of the second event; and transmit, as a second response of the multiple responses and in response to the second authorization request, the second token and the persistent identifier to the registered device. 16. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions, when executed by the one or more processors, cause the device to: receive, from the registered device, an account request; and transmit, to the registered device, a response to the account request indicating the account information with the persistent identifier. 17. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions, when executed by the one or more processors, cause the device to: transmit, to a data provider associated with the account information, an indication of the persistent identifier. 18. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions, when executed by the one or more processors, cause the device to: transmit an indication associated with the first token to a processing device included in the network. 19. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions, when executed by the one or more processors, cause the device to: receive, from a processing device included in the network, a detokenization request including the first token; and transmit, to the processing device, the account information in response to the detokenization request. 21. The non-transitory computer-readable medium of claim 15, wherein the one or more instructions, when executed by the one or more processors, cause the device to: determine a data provider of a plurality of data providers to forward the first authorization request based on a mapping of an indication included in the first authorization request to an identifier associated with the data provider; and forward, the first authorization request to the determined data provider. 35. The non-transitory computer-readable medium of claim 15, wherein the expiration of the first event is based on at least one of: after a single use for the first event, or an expiration of a threshold time period. Yes. But for the recited additional elements as shown above in bold, the remaining limitations of the claims recite certain methods of organizing human activity. The claims are directed to transaction authorization. This type of method of organizing human activity is a fundamental economic practice because it involves payments and a commercial interaction such as sales activities or behaviors and business relations. Thus, the claims recite an abstract idea. Step 2A, Prong Two: Is the Abstract Idea Integrated into a Practical Application? (see MPEP 2106.04(d)) No. The claims as a whole merely use a computer as a tool to perform the abstract idea. The computing components (i.e., additional elements that are in bold above) are recited at a high level of generality and are merely invoked as a tool to implement the steps. For example, only a programmed general purpose computing device (i.e., claimed “one or more processors of a device”) is needed to implement the claimed process. Simply implementing the abstract idea on a generic computer is not a practical application of the abstract idea. Additionally, there is no improvement to the functioning of a computer or technology. Therefore, the abstract idea is not integrated into a practical application. Step 2B: Does the Claim Provide an Inventive Concept? (see MPEP 2106.05) No. As discussed with respect to Step 2A, Prong 2, the additional elements in the claims, both individually and in combination, amount to no more than tools to perform the abstract idea. Merely performing the abstract idea using a computer cannot provide an inventive concept. Therefore, the claims do not provide an inventive concept. As such, the claims are not patent eligible.
