Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA  as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used.

Claim Rejections - 35 USC § 103
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, 5-9 and 13-20 are rejected under 35 U.S.C. 103 as being unpatentable over Ramachandran et al. (US PGPUB. # US 2018/0316492, hereinafter “Ramachandran”), and further in view of Kumar et al. (US PGPUB. # US 2020/0242249, hereinafter “Kumar”).
Referring to Claims 1, 9 and 17:
Regarding Claim 1, Ramachandran teaches,
A system comprising:
a memory  (Fig. 5(66)); and
a processor,  operatively coupled to the memory, to perform operations comprising: (Fig. 5(62))
receiving a request to provide a post-secrets-provisioning service with respect to a device  (¶81, Fig. 8(801), ¶106, “the injector 60 receives or intercepts an inbound message that contains a payload that is to be encrypted or an outbound message that contains a payload that is to be decrypted”, i.e. encrypting a payload or decrypting a payload is considered a request to provide a post-secret-provisioning service) [having a supply chain state corresponding to a supply chain associated with the device];
in response to receiving the request, determining whether to authorize the request; (¶88, “The authentication and authorization module 68 then processes that information to verify the identity of the sender”, Fig. 8(802), ¶106, “ the injector 60 may then verify that the request is authentic and that the requestor is authorized to encrypt or decrypt the data at that node 2”, i.e. determination is made to authorize the request)
in response to authorizing the request, obtaining a set of secrets data  (¶91, Fig. 8, ¶107-¶110, ¶111, “After obtaining the encryption information from memory or the controller 40, the injector 60 uses the encryption information at step 812 to assemble the encryption key”, i.e. secret data is obtain to assemble an encryption key) [corresponding to the supply chain state of the device]; and
providing the post-secrets-provisioning service by emulating, utilizing the set of secrets data, the device (¶92-¶93,  Fig. 8(813-814), ¶111, “at step 813, the injector 60 uses the assembled encryption key to encrypt or decrypt data, as the case may be. The assembly of the encryption key and the encryption or decryption may proceed using any of the methods and protocols discussed above. Once the data is encrypted or decrypted, the injector 60 transmits either the encrypted payload to the node 2 or the decrypted payload to the requesting entity”, i.e. encrypted/decrypted data is provided to the requesting entity) [having the supply chain state].
Ramachandran does not teach explicitly,
[receiving a request to provide a post-secrets-provisioning service with respect to a device] having a supply chain state corresponding to a supply chain associated with the device;
[in response to authorizing the request, obtaining a set of secrets data] corresponding to the supply chain state of the device; and
[providing the post-secrets-provisioning service by emulating, utilizing the set of secrets data, the device] having the supply chain state..
However, Kumar teaches,
[receiving a request to provide a post-secrets-provisioning service with respect to a device] having a supply chain state corresponding to a supply chain associated with the device; (Abstract, “a device historian, across a supply chain of device manufactures and managers, by a plurality of device management services”, ¶106-¶107, ¶118,  ¶121-¶122, “The analytics service may verify the received artifacts and process the operation request to prepare and transmit a record of the detected in-field device activity based on the policy trigger, comprising of at least the episode information, runtime state measurements and device integrity scores”, Fig. 17, ¶130, “FIG. 17 describes a block schema to track change management for a device through a supply chain from a silicon fabrication plant, an original equipment manufacturer (OEM), a platform owner, to a device owner as a distributed ledger in a blockchain “, ¶131,¶134, i.e. supply chain state of the device)
[in response to authorizing the request, obtaining a set of secrets data] corresponding to the supply chain state of the device; (Abstract, “a device historian, across a supply chain of device manufactures and managers, by a plurality of device management services”, ¶106-¶107, ¶118,  ¶121-¶122, “The analytics service may verify the received artifacts and process the operation request to prepare and transmit a record of the detected in-field device activity based on the policy trigger, comprising of at least the episode information, runtime state measurements and device integrity scores”, Fig. 17, ¶130, “FIG. 17 describes a block schema to track change management for a device through a supply chain from a silicon fabrication plant, an original equipment manufacturer (OEM), a platform owner, to a device owner as a distributed ledger in a blockchain “, ¶131,¶134, i.e. supply chain state of the device)  and
[providing the post-secrets-provisioning service by emulating, utilizing the set of secrets data, the device] having the supply chain state.. (Abstract, “a device historian, across a supply chain of device manufactures and managers, by a plurality of device management services”, ¶106-¶107, ¶118,  ¶121-¶122, “The analytics service may verify the received artifacts and process the operation request to prepare and transmit a record of the detected in-field device activity based on the policy trigger, comprising of at least the episode information, runtime state measurements and device integrity scores”, Fig. 17, ¶130, “FIG. 17 describes a block schema to track change management for a device through a supply chain from a silicon fabrication plant, an original equipment manufacturer (OEM), a platform owner, to a device owner as a distributed ledger in a blockchain “, ¶131,¶134, i.e. supply chain state of the device).
As per KSR vs Teleflex, combining prior art elements according to known methods (device, product) to yield predictable results may be used to create a prima facie case of obviousness.
It would have been obvious to one of ordinary skill in the art before the effective filing date to have combined the teachings of Kumar with the invention of Ramachandran.
Ramachandran teaches, providing a post secret provisioning service upon checking authorization of a request. Kumar teaches, providing an update service in a supply chain management where a cryptographic data corresponds to a state of the device. Therefore, it would have been obvious to provide an update service in a supply chain management where a cryptographic data corresponds to a state of the device of Kumar with providing a post secret provisioning service upon checking authorization of a request of Ramachandran to  provide significant improvements and efficiencies to retrofit legacy devices for protection and remote device management. KSR Int’l v. Teleflex Inc., 127 S. Ct. 1727, 1740-41, 82 USPQ2d 1385, 1396 (2007).
Regarding Claim 9, it is a method Claim of above System Claim 1 and therefore Claim 9 is rejected with the same rationale as applied against Claim 1 above.
Regarding Claim 17, it is a non-transitory computer-readable storage medium Claim of above System Claim 1 and therefore Claim 9 is rejected with the same rationale as applied against Claim 1 above.
Referring to Claims 5 and 13:
Regarding Claim 5, rejection of Claim 1 is included and for the same motivation Ramachandran does not teach explicitly,
The system of claim 1, wherein providing the post-secrets-provisioning service comprises at least one of: providing a data or trust verification service, providing a data production service, providing a file authorization service, or providing a service to locate a secrets and service provider system to handle the request.

The cited reference by Ramachandran et al. (US PGPUB. # US 2018/0316492) teaches, an  injector 60 overlays a node 2 in the blockchain network so that the injector 60 can intercept messages and encrypt their data before that data is inserted by the node 2 into new blocks on the chain. The injector 60 is communicatively coupled to both a node 2 in the blockchain and the controller 40. The injector 60 includes a processor 62, an encryption module 64, and it optionally includes a memory 66, an authentication and authorization module 68, an audit module 72, and a data analysis module 74. FIG. 5 provides a block diagram of some components of the injector 60. (¶81). Where the injector 60 receives or intercepts an inbound message that contains a payload that is to be encrypted or an outbound message that contains a payload that is to be decrypted. At step 802, the injector 60 may then verify that the request is authentic and that the requestor is authorized to encrypt or decrypt the data at that node 2. (Fig. 8*801), ¶106). For instance, the injector 60 includes an authentication and authorization module 68. When the injector 60 receives a new message, the injector 60 may transmit certain information to the authentication and authorization module 68. The authentication and authorization module 68 then processes that information to verify the identity of the sender and confirm that the sender has appropriate permissions to enter the data into the blockchain. Provided that the message is authenticated and authorized, the module may provide a confirmation to the injector 60. (¶88). The encryption information is retrieved from the optional memory 66 or requested from the controller 40. Specifically, in embodiments where the injector 60 includes a memory 66 that stores sets of encryption information, the injector 60 (or the encryption module 64) may first check the memory 66 for valid encryption information. If the memory 66 does not contain encryption information (or if it contains expired encryption information), the injector 60 transmits an Encryption Information Request to the controller 40. As discussed above, the controller 40 will, assuming receipt of a valid Encryption Information Request, return the requested encryption information to the injector 60. (¶91). At step 803, the injector 60 determines whether it currently possesses the encryption information that is required to encrypt or decrypt the data. As discussed above, an injector 60 may temporarily store encryption information, or in some embodiments, it may persistently store certain types of encryption information. If the injector 60 possesses the necessary encryption information, the process may skip to step 812. Otherwise, the injector 60 must request the encryption information from the controller 40 and the process proceeds to step 804, where the injector 60 transmits a request to the controller 40 for the encryption information. The request may be the Encryption Information Request discussed above. Next, at step 805, the controller 40 determines whether it possesses the encryption information requested by the injector 60. In some embodiments, the controller 40 may not store encryption information in its memory, in which case step 805 may be skipped. But if the controller 40 does possess the requested encryption information, the process may then skip to step 811. If the controller 40 does not possess the information, the controller 40 proceeds to step 806, where it transmits a request to the generator 20 for the encryption information. The request may be the New Key Command discussed above. The generator 20 receives the request and, at step 807, determines whether the generator 20 already possess an encryption key that is applicable to the requesting entity. If the generator 20 does not possess such an encryption key, the generator proceeds to step 808 to generate a new encryption key for the requesting entity. This step may proceed as described above and may include various authentication or authorization checks before generating the encryption key. Once the generator 20 possesses the appropriate encryption key, whether retrieved from its memory or newly generated, it derives encryption information from the encryption key at step 809. Note however that, in some embodiments, the generator 20 may store encryption information in memory, in which case the generator 20 may not generate new encryption information. The generator 20 then proceeds to step 810 and transmits the requested information to the controller 40. At step 811, the controller 40 possess the requested encryption information (whether from memory or through a request to the generator) and transmits the information to the requesting injector 60. Optionally, the controller 40 may also store the encryption information in its memory, but in many embodiments, the encryption information does not persist on the controller 40. After obtaining the encryption information from memory or the controller 40, the injector 60 uses the encryption information at step 812 to assemble the encryption key. Then, at step 813, the injector 60 uses the assembled encryption key to encrypt or decrypt data, as the case may be. The assembly of the encryption key and the encryption or decryption may proceed using any of the methods and protocols discussed above. Once the data is encrypted or decrypted, the injector 60 transmits either the encrypted payload to the node 2 or the decrypted payload to the requesting entity. The injector 60 also, at step 815, destroys the assembled encryption key so that it does not persist in memory. Depending on the embodiment, the injector 60 may, however, store the encryption information in memory. As discussed above, the encryption information may persist for a limited duration of time or only so long as certain conditions are satisfied. [0112] 3. Obtaining Quorum to Encrypt Data (Fig. 8, ¶107-¶111). Using the pertinent encryption information (whether retrieved from memory 66 or a request to the controller 40), the encryption module 64 proceeds with encrypting the data in the message. As discussed above, the encryption module 64 may use any known technique for encryption, and in a preferred embodiment, it uses the Advanced Encryption Standard. The OpenSSL library is one example of a suitable library for encrypting the message, but any other suitable code library may be used. Before calling the encryption function, an array may be generated based on the size of the message and based on any padding required to accommodate the soon-to-be encrypted message. Thereafter, an encryption function may be called and supplied with the message, the encryption key, and the padded array. The function will then return an array containing the encrypted message. In some embodiments using key shares (such as those based on Shamir's Secret Sharing Algorithm or another key sharing algorithm or protocol), the encryption process may require the injector 60 to cooperate with other injectors in the system 10 to obtain at least k key shares to enable encryption of the data. The injectors 60 are communicatively coupled to one another to accomplish this process, which may be referred to as obtaining quorum. The requirement of quorum is often imposed when multiple parties share an encryption key that is used to encrypt data that is shared between the parties. In general terms, the quorum process requires the injector 60 to contact other injectors and request that they provide their key shares so that at least k key shares are available to reassemble the encryption key. The different processes for obtaining quorum are more fully described below. The encryption key can then be assembled from the at least k key shares and be used to encrypt or decrypt data. Ordinarily, the encryption key is thereafter deleted. In many embodiments, the key shares obtained from other injectors are also deleted, although in some situations, the injector 60 may be permitted to retain the key shares in secure memory for a limited duration of time or based on certain conditions. Certain injectors 60 may also be classified as “trusted” injectors, in which case they may have greater rights to retain key shares. Retaining key shares in memory 66 may be advantageous to enhance processing speed and availability of the system 10. (¶92-¶93).
The reference by Charfi et al. (US PGPUB. # US 2013/0151317) discloses, an example architecture 100 can be used to realize implementations of SPLM in accordance with the present disclosure. For example, the client computing device 102 and/or the user 104 may be a service consumer that accesses and uses one or more services provided by the SPL. As discussed in further detail herein, the SPL involves a service broker 120, one or more service providers 122, one or more service aggregators 124, one or more service channel makers 126, one or more service hosters 128, and one or more service gateways 130. (¶28). The service consumer 214 completes the service supply chain that is effectively fostered by the SDF 200. Thus, the service consumer 214 discovers, selects, configures, negotiates, orders, and consumes the service with the goal of co-creating business value. Through the service consumer 214, parties can manage the last mile integration where services are consumed through different environments. This involves the allocation of resource consuming services to consumer environments in which they operate and the interfacing of consumer environments so that the services required can be accessed at run-time in a secure and reliable way. (¶51). Referring now to FIG. 4, a state diagram 400 of an example service provisioning lifecycle (SPL) model for service provisioning lifecycle management (SPLM) in an SDF is depicted. The SPL model for SPLM can include several stages, or states, and transitions between states. In some implementations, a service transitions from one state to another after one or more provisioning steps have been performed. In some examples, particular users can modify particular artifacts during a state transition. In some examples, service provisioning states can include one or more of Lodged (402), Registered (404), Failed (406), Rejected (408), Brokered (410), Gatewayed (412), Cloud-hosted (414), Channeled (416), and Consumable (418). In some examples, a state can be both Gatewayed and Cloud-hosted (420) at the same time. (Fig. 4, ¶65). FIG. 2 is a block diagram of an example service delivery framework (SDF) 200. The SDF 200 supports a variety of provisioning partners as seen through different roles. In some implementations, the roles include service provider 202, service broker 204, and service aggregator 206. The SDF 200 further includes service channel maker 208, service gateway 210, service hoster 212 and service consumer 214. Different provisioning partners can use particular platform functionalities dedicated for their service provisioning niches, as discussed in further detail below. The functionality offered through the SDF roles combines technical capabilities (e.g. service composition tools, service repository, service adaptation and runtime environment, and network convergence) with business functionality (e.g. customer relations management (CRM) and payments) for supporting various forms of service delivery. Service delivery can be drawn from a foundation layer of components accessed through a service-oriented architecture (SOA) enabled business process platform. In some implementations, an architectural strategy for the SDF 200 recognizes that industry-specific applications 216 may be needed for business networks operating in different industries. Example applications that apply to industry-specific business networks (e.g., eGovernment platforms for one-stop citizens and constituent services) can provide user interfaces (UIs) and logic that, while coded against a generic SPL layer, are specific to particular domains. Example applications can include enterprise applications 218, public sector applications 220, banking applications 222, and transport and logistics applications 224. In some implementations, the applications can be separately deployed as on-premise installations for customers. In some implementations, the applications can be run as on-demand for several customers. Because a variety of domains are targeted, the SDF 200 supports diverse services and diverse consumption modes. (Fig. 2, ¶30-¶31).

The method can include building, on the development system 604, an update package including at least one of a firmware update, a software update, a configuration update, and an update script. The method can include signing, by the release management system 608, the update package 607 using a provider signing key 609, wherein a first digital signature is included in the update package. The method can include encrypting, by the release management system 608, the signed update package using a publisher public key from a publisher certificate 610 for the update publisher 602 for initial encryption of the update package. The method can include sending, by the release management system 608, the signed and encrypted update package 611 to the update service 107. The method can include requesting, by the update client 603 on the device 101, 102, an update package. The request can include at least the vendor identifier, the model number, and a device certificate 613 for the device. The method can include resigning, by the update service 107, the signed update package using a publisher signing key 618. A second digital signature is included in the update package. The method can include reencrypting, by the update service 107, the doubly signed update package by decrypting the initial encryption using a publisher private key from the update publisher 602, and encrypting the update package using a device public key from the device certificate 613, for final encryption of the update package. The method can include sending, by the update service 107, the encrypted and doubly signed update package 619 to the update client 603 on the device 101, 102. The method can include decrypting, by the update client 603, the encrypted update package using a device private key for the device 101, 102. The method can include verifying, by the update client 603, the first and second digital signatures using the respective public keys from the update provider 601 and publisher certificates issued by a certificate authority 406. In an exemplary embodiment, the update script is executed on the device to apply the update package to the device 101, 102. (¶101).
