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.

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.
Claims 1-20 are 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.
Claims 1, 8, and 15 recite “generate[ing] and store[ing] a wallet private key of a wallet public-private key pair of the first token or a first private key of the first public-private key pair of the first token and at least a first portion of metadata of the metadata object.” Claims 1, 8, and 15 disclose generating a first public-private key pair for a first token. The generated first public-private key pair includes a private key. Claims 1, 8, and 15 further discloses generating and storing a wallet private key of a wallet public-private key pair of the first token or a first private key of the first public-private key pair of the first token. Therefore, the manner of generating an already generated first private key of the first public-private key pair is unclear if it is generated by the step of generating and storing. For examination purpose, the limitation is interpreted as “generate and store an object comprising a wallet private key of a wallet public-private key pair of the first token or a first private key of the first public-private key pair of the first token and at least a first portion of metadata of the metadata object.”
Dependent claims 2-7, 9-14, and 16-20 are rejected because they depend on the rejected independent claims 1, 8, and 15, respectively.
Citation of Pertinent Prior Art
The closest prior art is as follows:
Franco et al. (US 20240152905 A1) discloses minting and managing NFTs. An NFT is minted via a blockchain operation request, and the NFT is assigned to the cryptography-based storage application, e.g., a digital wallet. The digital wallet can be identified on the blockchain using a unique cryptographically generated address, e.g., a public key of the public-private key pair. The digital wallet could be an air-gapped wallet to act as a cold storage. A secure memory included in the digital wallet may store a private key of a public-private key pair and metadata associated with various tokens. Each of the NFTs comprises a resource identifier, which can include a link to a location storing metadata associated with the NFTs. The access of the metadata is restricted by encrypting the resource identifier and payload with a public key of a user device.
Clark et al. (US 20230139878 A1) discloses a method and a system for long-term authentication of NFTs. An NFT is recorded as being located at a public address on a blockchain, and it is accessible via a corresponding private key of an asymmetric key pair to the public address. The NFT comprises a link to the location of an off-chain storage storing metadata associated with the NFT. The off-chain storage may store a deed, title documents, and historical documentation of previous sales or records that establish a chain of ownership up to the creation of the NFT.
Zhou et al. (US 20190207770 A1) discloses a method for access control of contract data in a distributed system. The digital contract data may include a first portion of public data and a second portion of private data. The second portion of private data can be removed from the digital contract data to generate a partial content of the digital contract data. The generated partial content of the digital contract data can be stored in a separate storage.
Silver (US 20230162188 A1) discloses an offline wallet management (OWM) system for managing blockchain transaction approval using private encryption keys stored offline. A user of the system may have at least one associated offline device to store one or more private keys. The OWM system may include one or more off-chain databases storing information about current and/or past ownership of one or more cryptographic coins or NFTs.
Wright et al. (US 20190130391 A1) discloses utilizing a title registry database, as an overlay ledger, to track the ownership of tokens. The title registry database maintains a record of a change of ownership of a token (T), i.e., the fact that the ownership has changed, without explicitly identifying the current owner of the token (T). If a transaction has been recorded on the title registry database, the title store registry database may include at least one of the transaction identifier and the output script of a transaction, which includes an indication of the current owner, i.e., the public key of the current owner, embedded within metadata of the redeem script hash. The previous owner may be determined from his/her public key identified in the unlocking script of the input section of the transaction.
The cited references, alone or in combination, do not teach the specific combination of generating a first public-private key pair for a first token, wherein a first public key of the first public-private key pair identifies a first internal address of a plurality of internal addresses on a blockchain storage; encapsulating the first token within a first control structure that restricts a first output of a metadata object, the first token comprising a first link to the metadata object; updating a token account of a plurality of token accounts in an overlay ledger by recording ownership of the first token with the token account; generating and storing an object comprising a wallet private key of a wallet public-private key pair of the first token or a first private key of the first public-private key pair of the first token and at least a first portion of metadata of the metadata object, wherein the first portion of metadata of the metadata object of the first token associated with protected data of the first token; removing the first portion of metadata of the metadata object of the first token based at least in part on accessing the metadata object via the first link; broadcasting the first token to the blockchain storage at the first internal address; and tracking, utilizing the overlay ledger, an association of token ownership of a plurality of tokens with the plurality of token accounts, wherein each token of the plurality of token s is recorded and tracked with a respective token account of the plurality of token accounts.
Conclusion
The prior art, made of record and not relied upon, is considered pertinent to the applicant’s disclosure.
Brannan et al. (US 20240135362 A1) discloses implementing a medical data non-fungible token (NFT). One or more processors receive medical data of a plurality of users, and store the medical data of the plurality of users in a first storage location in a medical data database. The one or more processors may then detect a request to purchase a data feed for one or more types of medical data, and identify medical data corresponding to the request in the medical data database. The one or more processors may then store the identified medical data in a second storage location, and mint a medical data NFT that indicates the second storage location. The data owner may reserve the right to withdraw the NFTs from the marketplace, even if data owner does not own the corresponding NFT. For example, the smart contract may be configured to detect revocation requests written to the distributed ledger. Upon validating that the revocation request was submitted by the data owner, the smart contract may transfer ownership of the NFT to the data owner, update the access rights of the NFT smart contract to prevent third party access to the digital asset, and/or cause the medical data to be deleted from the location indicated in the NFT.
Bhujel et al. ("A Survey: Security, Transparency, and Scalability Issues of NFT's and Its Marketplaces," November 2022) discloses a process of recording and processing NFTs based on a blockchain. After the transaction including an NFT and the metadata of the NFT are received, the NFT is validated. The data associated with the transaction is stored in an external or internal database, and the NFT is stored in the blockchain. Bhujel further discloses generating public- private key pairs on a blockchain, and the blockchain address can be derived from the public key. The NFT wallet could be a cold wallet, and the cold wallet can be used to store a private key and digital assets.
