Office Action

§103 §112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Acknowledgements The reply filed 01/29/2026 is acknowledged. Claims 1-2, 6, 9, 14-15, and 18 have been amended. Claim 5 has been canceled. Claims 1-4 and 6-20 are pending and presented for examination. Response to Arguments Applicant's amendments, filed 01/29/2026, have overcome the 35 U.S.C. 112(b) rejection of claims 2-3, 9-10, 15-16, and 18 previously set forth in the Non-Final Rejection 10/29/2025. Therefore, the 35 U.S.C. 112(b) rejection of claims 2-3, 9-10, 15-16, and 18 has been withdrawn. Applicant's arguments filed 01/29/2026 have been fully considered, but they are not persuasive. In response to Applicant’s remarks regarding the whitelist, the claimed invention does not claim that the whitelist is a whitelist membership that “requires a credential server approval process, initiated by user requests, payment confirmation, or referral-based authorization, creating a controlled eligibility list.” There are no actively recited steps or operations in the claimed invention that require such generation process of a whitelist from which one or more user devices is selected. Since the whitelist has been generically recited in amended independent claims 1 and 14, it is reasonable to interpret the whitelist to be merely a stored list of devices. Furthermore, the claimed invention does not claim any limitations related to “new users can raise a request…for becoming a member of the whitelist…raise a purchase request or can adopt a referral system to be a part of the whitelist.” Therefore, Applicant’s remarks cannot be persuasive since the claimed invention does not claim any limitations related to the whitelist as denoted in the remarks on pg. 9. Furthermore, the Examiner noted in the Non-Final Rejection 10/29/2025 that the content of the first information is nonfunctional descriptive material because it does not meaningfully limit how the first information is rendered see MPEP 2111.05. Therefore, the content of the first information, i.e. presale notifications to one or more user devices selected from a whitelist stored in the first database, cannot be given patentable weight. However, for purposes of compact prosecution, prior art citation was provided in the rejection. Applicant’s remarks, filed on 01/29/2026, have failed to address this interpretation of the claims. Therefore, the content of the first information is not given patentable weight, and the newly added limitation to claims 1 and 14 only requires that the first information is being transmitted. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 6 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 6 depends from claim 5. Claim 5 has been canceled in the most recent amendments filed 01/29/2026. Therefore, claim 6 is indefinite because it is unclear what limitation(s) the claim is supposed to include. The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claim 6 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim 6 depends from claim 5, which has been canceled. Therefore, claim 6 cannot further limit a claim that has been canceled and cannot include all of the limitations of a canceled claim. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. For purposes of compact prosecution and application of the prior art, claim 6 shall be interpreted to be dependent from claim 1. Claim Rejections - 35 USC § 103 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 (i.e., changing from AIA to pre-AIA ) 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. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1-2, 4, 7-10, 12-15, and 17-19 are rejected under 35 U.S.C. 103 as being unpatentable over Johnson et al. WO 2017/136579 (herein as “Johnson”) in view of Kang et al. WO 2021/054989 (herein as “Kang”), and further in view of Hermann U.S. 2012/0215637. Re Claim 1, Johnson discloses a method for tamper-proof assignment and tracking of tickets to access an event for a defined period of time, to at least one user device, the method comprising: rendering, via a credential server, first information associated with the event to the at least one user device ([0071] – “web-server system 318 (i.e. credential server) can interact with user device 310 to identify available tickets and to collect information needed to assign an ticket. Web-server system 318 can interact with SQL system 341 so as to retrieve data about particular events and/or tickets (i.e. first information) to as to configure web data…to reflect accurate or semi-accurate information and/or statuses,” i.e. rendering first information to the user device); receiving a request for the tickets from the at least one user device in response to the rendered first information, wherein the request includes at least one of a location associated with the event and a number of tickets requested by the at least one user device ([0020] – “Notifications of available tickets can be accompanied by options to request that one or more tickets be assigned to a user (i.e. in response to the rendered first information). Therefore, user 105 can provide input to user device 110 via an interface to request such assignment and provide other pertinent information…In some instances, a request includes one or more access to a particular event (i.e. number of tickets)…an event location.”); extracting information from a first database based on the request received from the at least one user device, wherein the extracted information includes a list of unfilled tickets requested by the at least one user device with parameters including at least one of the location associated with the event, a type of tickets requested by the at least one user device, and identifiers associated with the tickets ([0071] – “Web-server system 318 can interact with SQL system 341 so as to retrieve data about particular events and/or tickets…Catalog system 342 may provide condensed status updates (e.g. reflecting a binary indication as to whether an ticket is available) to SQL system 341 (i.e. an unavailable ticket is analogous to an unfilled ticket),” [0060] – “The relational databases can include…for example, event information, access-right identifications and characteristics (i.e. identifiers associated with the tickets), access-right statuses and/or assignments, and/or user and/or user account data”); assigning, via the credential server, the tickets, from the list of unfilled tickets to an account associated with the at least one user device based on the received request ([0024] – assigning a ticket to a user, [0113] – assigning tickets responsive to a request); assigning, by the credential server, […] a colored coin, linked with the tickets, to the account associated with the at least one user device based on the assignment of the tickets from the list of unfilled tickets, […] ([0014] – “A colored bitcoin, access token, or access token identifier ties an event (i.e. linked with the tickets) to a bitcoin transaction or other trustless ledger transaction so that the transfer and ownership of the event (i.e. assigning to the account) can be traced through the block chain of the trustless ledger transaction. An event can be a ticket to a restricted area…” [0184] – “a cryptocurrency block chain to provide for use of a colored cryptocurrency element that represents a particular access-right (i.e. assignment of the ticket),” [0185] – the colored cryptocurrency element associated with the access-right is granted to the user); acquiring, by the credential server, personal identification information of the account associated with the at least one user device ([0061] – “generate status-update request communications to be sent to one or more access assignment systems and/or intermediate systems…a status-update communication identifies assignment details, such as a user, account and/or user device associated with an access-right assignment”); updating the decentralized blockchain and the first database in response to the acquired personal identification information associated with the at least one user device, wherein the update in the decentralized blockchain and the first database is adapted to provide real-time consistency by maintaining operations between distributed nodes and the first database ([0013] – “the distributed database may be decentralized and trustless,” [0014] – “transfer and ownership of the event can be traced through the block chain of the trustless ledger transaction,” [0060] – “The relational databases can include…include user and/or user account data, etc.”); Examiner notes that the “wherein” (“the update…is adapted to…) clause is an intended result of updating decentralized blockchain and the first database and is therefore, not given patentable weight since it does not limit how the updating is performed. However, for purposes of compact prosecution, prior art is provided: [0098] – “Updates to data stores…can improve cross-device data consistency.” transmitting the first information, wherein the first information includes presale notifications to one or more user devices selected from a whitelist stored in the first database ([0018] – notifications of available rights are transmitted to a set of user devices, a set being analogous to a whitelist. The available rights are not yet sold, and are therefore “presale,” [0093] - account data store 424 can store data for entities, users, account data, and/or information such as one or more device types, IP addresses, etc., “whitelist stored in the first database”); Examiner notes that the content of the first information is nonfunctional descriptive material because it does not meaningfully limit how the first information is rendered see MPEP 2111.05. Therefore, the content of the first information cannot be given patentable weight. However, for purposes of compact prosecution, prior art citation is provided above. transmitting a notification to the at least one user device, wherein the notification comprises a confirmation of assignment of the tickets […] to the account associated with the at least one user device [0141]; Examiner notes that the content of the notification is nonfunctional descriptive material because it does not meaningfully limit how the notification is transmitted see MPEP 2111.05. Therefore, the content of the notification cannot be given patentable weight. However, for purposes of compact prosecution, prior art citation is provided above. verifying a validity of the tickets […], when the at least one user device is requesting access to the event, based on scanning information provided on the tickets and referencing a transaction history […] in the decentralized blockchain […] ([0180] – “a user being in possessing the private key…may be an indicator that the user has a valid ticket for a particular venue…verification of a user possess an ticket may be established by confirming the user is in possession of the corresponding private key,” [0181] – “a private key…may be represented…in a physical form (e.g. a barcode or quick response (QR) code)…user is required to transfer the cryptocurrency element (associated with the ticket, enabled by possession of the private key)…to obtain entry to a venue,” [0173] – “On the full block chain, each and every cryptocurrency element and all transfers of all cryptocurrency elements ever made are accounted for, allowing verification of which addresses control which cryptocurrency elements at any given moment”); […] transmitting at least one updated […] colored coin and privilege to access the event to the at least one user device based on the verification of the tickets […] ([0186] – the same or another, i.e. updated, colored cryptocurrency element may be transferred to the user upon exit to grant the user access for re-entry if the user is eligible). Although Johnson discloses using “colored coins,” which are similar to the NFTs in the instant application regarding the representation and tracking of real-world assets, Examiner recognizes that Johnson does not expressly disclose using NFTs. Specifically, Johnson does not expressly disclose a unique non-fungible token (NFT), linked with the tickets; the NFT is the unique non-fungible token in a decentralized blockchain, and the NFT is stored in the decentralized blockchain configured to maintain secure and transparent transaction history of the tickets for future traceability; updating transaction record of the assigned NFT in the decentralized blockchain; the transaction history includes the transaction record of the NFT. Kang discloses an online platform for commerce in a distributed system with blockchain protocols and smart contracts. Specifically, Kang discloses a unique non-fungible token (NFT), linked with the tickets [0047] – “The term “non-fungible” token, as used herein, may refer to a live even ticket that has been tokenized.”; the NFT is the unique non-fungible token in a decentralized blockchain ([0047] – “Non-fungible tickets are never the same (i.e. unique),” [0103] – “as each new event is created…as each tickets/token is purchased, or as an ownership interest of a current ticket/token is transferred, a new entry to the blockchain 110 is added”), and the NFT is stored in the decentralized blockchain configured to maintain secure and transparent transaction history of the tickets for future traceability ([0056] – “Systems and methods described herein relate to a decentralized blockchain-based online ticketing platform that may achieve trust between the user community using openness, provide transparency of operation, and create a ticketing platform on which all ticket data (i.e. NFT) is stored “on-chain”); Examiner notes that “configured to maintain…” is an intended result. It does not meaningfully limit how the NFT is stored. Therefore, it cannot be given patentable weight. However, for purposes of compact prosecution, prior art citation is provided above. updating transaction record of the assigned NFT in the decentralized blockchain [0103] – “as each new event is created…as each tickets/token is purchased, or as an ownership interest of a current ticket/token is transferred, a new entry to the blockchain 110 is added.”; the transaction history includes the transaction record of the NFT [0103] – “all parties may monitor the comprehensive transaction history in real-time to validate ticket ownership,” “as each new event is created…as each tickets/token is purchased, or as an ownership interest of a current ticket/token is transferred, a new entry to the blockchain 110 is added.” It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Johnson’s decentralized virtual trustless ledger for ticketing control with the teachings of using NFTs to represent tickets in Kang. One would be motivated to make this combination because NFTs are a known, obvious variant of colored coins, and it would have been obvious to try with a reasonable expectation of success. However, Johnson in view of Kang do not explicitly teach monitoring one or more in-venue user interactions to: identify an in-venue transaction by the at least one user device, and assign an additional NFT or an interaction reward based on the in-venue transaction. Hermann discloses a system and method that permits a user at a venue location to be more effectively engaged by a venue operator. Specifically, Hermann discloses monitoring one or more in-venue user interactions to [0025] – “actions performed by the user among multiple applications and venue locations are monitored by a loyalty system”: identify an in-venue transaction by the at least one user device [0073] – “information that may be tracked may include purchasing behavior of the user,” and assign an additional NFT or an interaction reward based on the in-venue transaction [0121] – “monitoring and rewarding user behavior,” “may perform one or more actions at the venue location,” “a reward is communicated to the mobile device operated by the user.” It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to combine Johnson in view of Kang’s decentralized virtual trustless ledger for ticketing control with the teachings of monitoring and rewarding a user based on the user’s transactions in Hermann. One would be motivated to make this combination to improve user engagement and thereby provide better services to users during an event Hermann, [0088]. Re Claim 2, Johnson in view of Kang and Hermann teach the method of claim 1, and Johnson in view of Kang and Hermann further teach further comprising transferring ownership of the NFT linked with the tickets based on personal identification information associated with an account of a second user who is at a receiving destination (Johnson [0188] – transferring the ticket represented by the colored cryptocurrency element to an address controlled by a second user, i.e. personal identification information associated with an account of a second user). Re Claim 4, Johnson in view of Kang and Hermann teach the method of claim 1, and Johnson in view of Kang and Hermann further teach further comprising prioritizing user devices for accessing privileges or other tickets based on NFTs owned by a user, associated with a user device of the user devices, and past history stored in the first database (Johnson [0108] – prioritizing requests based on similar or same tickets, i.e. owned by a user, earlier requests, whether requests were associated with users having established accounts, i.e. past history, etc.). Re Claim 7, Johnson in view of Kang and Hermann teach the method of claim 1, and Johnson in view of Kang and Hermann further teach wherein the first database storing at least one of historical data associated with the at least one user devices, user preferences, user behavior, location information associated with the at least one user device, a list of available tickets, the NFT assigned to the user device, and social media account information associated with the at least one user device Johnson [0060], [0071]. Re Claim 8, Johnson in view of Kang and Hermann teach the method of claim 1, and Johnson in view of Kang and Hermann further teach further comprising managing the personal identification information and the NFT assigned to the at least one user device using the decentralized blockchain (Johnson [0171] – an address is analogous to personal identification information). Re Claim 9, Johnson in view of Kang and Hermann teach the method of claim 1, and Johnson in view of Kang and Hermann further teach further comprising linking the acquired personal identification information with the assigned NFT (Johnson, [0114] – “store an indication in account data store 424 that the ticket(s) have been assigned to the user,” assigning is analogous to linking); registering the linked personal identification information in the first database (Johnson, [0114] – “store an indication in account data store 424 that the ticket(s) have been assigned to the user,” storing the indication is analogous to registering in the first database). However, Johnson does not expressly disclose verifying the personal identification information linked with the NFT by comparing it with the personal identification information registered in the first database. Kang discloses an online platform for commerce in a distributed system with blockchain protocols and smart contracts. Specifically, Kang discloses verifying the personal identification information linked with the NFT by comparing it with the personal identification information registered in the first database [00101] – identification verification includes providing information such as biometric-based ID to secure a user’s account such that they could repeat the verification process again, i.e. comparing with personal identification information, to recover wallets or purchased tickets. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Johnson’s decentralized virtual trustless ledger for ticketing control with the teachings of verifying identity of a user by comparing personal identification information with previously provided personal identification information in Kang. One would be motivated to make this combination to improve security of the account and eliminate bots Kang [00101]. Re Claim 10, Johnson in view of Kang and Hermann teach the method of claim 9, and Johnson in view of Kang and Hermann further teach further comprising rendering the tickets associated with the NFT to the at least one user device based on the verification of the personal identification information of a user, associated with the at least one user device, registered in advance, and wherein the verified personal identification information is stored in the first database (Kang [00101] – identification verification includes providing information such as biometric-based ID to secure a user’s account such that they could repeat the verification process again, as needed, to recover purchased tickets, i.e. rendering the tickets). It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Johnson’s decentralized virtual trustless ledger for ticketing control with the teachings of providing tickets based on verifying the identity of a user in Kang. One would be motivated to make this combination to improve security of the account and eliminate bots Kang [00101]. Re Claim 12, Johnson in view of Kang and Hermann teach the method of claim 1, and Johnson in view of Kang and Hermann further teach further comprising defining a transfer method of the tickets linked to the NFT based on a smart contract of the decentralized blockchain, wherein the transfer method defines an identifier at which the user device circulates the tickets (Kang [0017-18] – using smart contracts to sell, or transfer, a live event ticket as a non-fungible token, a transaction identifier is defined for facilitating the transaction). It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Johnson’s decentralized virtual trustless ledger for ticketing control with the teachings of using smart contracts to define rules regarding sale and resale of live event tickets in Kang. One would be motivated to make this combination because implementing smart contracts with a blockchain would enable the ability to control end-to-end commerce so that revenue may be recaptured and distributed in a controlled and orderly manner, e.g. controlled by a rule set or rule sets Kang [0003]. Re Claim 13, Johnson in view of Kang and Hermann teach the method of claim 1, and Johnson in view of Kang and Hermann further teach further comprising transmitting the tickets to a user, via the credential server, based on referencing the transaction history of the NFT in the decentralized blockchain and verifying the transaction history in accordance with one or more rules of a ticket transfer method linked to the NFT (Kang [0018] – sale and resale of live event ticket may correspond to at least one smart contract deployed on a blockchain, and [00103] - transaction history may be monitored in real-time to validate ticket ownership as each ticket/token is purchased or transferred). It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Johnson’s decentralized virtual trustless ledger for ticketing control with the teachings of referencing the blockchain and employing smart contracts in Kang. One would be motivated to make this combination because implementing smart contracts with a blockchain would enable the ability to control end-to-end commerce so that revenue may be recaptured and distributed in a controlled and orderly manner, e.g. controlled by a rule set or rule sets Kang [0003]. Re Claims 14-15 and 17-19, they are the non-transitory machine-readable storage medium claims of method claims 1-2, 4, 7 and 9. They recite similar distinguishing features as claims 1-2, 4, 7 and 9. Furthermore, Johnson discloses a storage medium, such as a non-transitory storage medium, that can be used to store program code for each of one or more of the components, modules, and/or engines depicted in the prior art [0133]. Therefore, they are rejected for the same reasons above. Claims 3 and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Johnson et al. WO 2017/136579 (herein as “Johnson”) in view of Kang et al. WO 2021/054989 (“Kang”) and Hermann U.S. 2012/0215637 as applied to claims 2 and 15 above, and further in view of Sehrer U.S. Patent 8,983,868. Re Claim 3, Johnson in view of Kang and Hermann teach the method of claim 2, however, Johnson in view of Kang and Hermann do not explicitly teach wherein transferring the ownership of the NFT includes, giving privilege related to the transfer of the ownership to the second user, associated with a second user device, who is at the receiving destination, and wherein the second user is eligible as the receiving destination based on a participation score for accessing the event or based on an index value associated with a social medial ID of the second user as an action history of the second user. Sehrer discloses using location information in electronic commerce. Specifically, Sehrer discloses if a score calculated by the social module is above a threshold, the purchase transaction is approved (i.e. giving privilege) Col. 9, lines 58-61. The score (i.e. index value) is calculated based on the social networking information of the user (i.e. social media ID) Col. 11, lines 11-12. The user making the purchase is analogous to the second user as the receiving destination. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Johnson in view of Kang and Hermann’s decentralized virtual trustless ledger for ticketing control with the teachings of using a calculated score of the user to approve or deny the transaction in Sehrer. One would be motivated to make this combination to reduce fraudulent transactions Sehrer Col. 1, lines 11, 19-20, Col. 4, lines 65-67. Re Claim 16, it is the non-transitory machine-readable storage medium claim of method claim 3. It recites similar distinguishing features as claim 3. Therefore, it is rejected for the same reasons above. Claims 6 , 11, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Johnson et al. WO 2017/136579 (herein as “Johnson”) in view of Kang et al. WO 2021/054989 (herein as “Kang”) and Hermann U.S. 2012/0215637 as applied to claims 1, 5 and 14 above, and further in view of Yantis et al. WO 2020/092900 (herein as “Yantis”). Re Claim 6, Johnson in view of Kang and Hermann teach the method of claim 5, however, Johnson in view of Kang and Hermann do not explicitly teach further comprising generating the whitelist that includes a list of approved user devices based on a comparison of personal identification information associated with one or more user devices with corresponding information stored in the first database. Yantis discloses a tokenization platform. Specifically, Yantis discloses maintaining and updating a public address list of valid accounts [0891]. The account of the user is verified based on the public address of the user, i.e. personal identification information [0027]. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Johnson in view of Kang and Hermann’s decentralized virtual trustless ledger for ticketing control with the teachings of updating and maintaining a list of valid accounts in Yantis. Since each individual element and its function are shown in the prior art, albeit shown in separate references, the difference between the claimed subject matter and the prior art rests not on any individual element or function but in the very combination itself. Therefore, the combination of prior art elements according to known methods would yield predictable results and renders the claim obvious. Re Claim 11, Johnson in view of Kang and Hermann teach the method of claim 1, however, Johnson in view of Kang and Hermann do not explicitly teach wherein the NFT is issued in the decentralized blockchain in which nodes permitted by an administrator can participate, and wherein the NFTs are stored either in a non-custodial wallet accessible on the user device or in a custodial wallet accessible to NFT issuer. Yantis discloses a tokenization platform. Specifically, Yantis discloses a distributed ledger may be private [0884], i.e. blockchain in which nodes permitted by an administrator can participate. Furthermore, Yantis discloses tokens can be assigned to a user’s wallet [0847]. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Johnson in view of Kang and Hermann’s decentralized virtual trustless ledger for ticketing control with the teachings of issuing NFTs on a private blockchain and storing the NFTs in a user’s wallet in Yantis. One would be motivated to make this combination because these are known variations in blockchain technology (private vs. public blockchain, custodial vs. non-custodial wallets) and it would have been obvious to try with a reasonable expectation of success. Re Claim 20, it is the non-transitory machine-readable storage medium claim of method claim 11. It recites similar distinguishing features as claim 11. Therefore, it is rejected for the same reasons above. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
