Election/Restrictions
Applicant’s election with traverse of Group I, claims 1-7 and 13-19 in the reply filed on 11/12/2025 is acknowledged.
Claims 8-12 and 20-24 are withdrawn from further consideration pursuant to 37 CFR1.142 (b), as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 11/12/2025. The traversal is on the ground(s) that no undue burden exists on examining the groups together. This is not found persuasive because the groups were shown to be distinct for the reasons given in the Restriction Requirement mailed on 9/15/2025 and have acquired a separate status in the art because of their recognized divergent subject matter, restriction for examination purposes as indicated is still deemed proper and is therefore made FINAL.
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 1-7 and 13-19 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more.
Analysis
In the instant case, claims 1-7 are directed to a method, claims 13-19 are directed to an apparatus. Therefore, these claims fall within the four statutory categories of invention.
The claim(s) recite(s) processing transaction request. Specifically, the claims recite “determining, by a first [node], a first message; and sending, by the first [node], the first message, wherein the first message comprises at least one of request information or information about a first transaction, the request information is useable to request to modify a second transaction, the first transaction is a modified second transaction, the second transaction is stored in a first [blockchain], the first [blockchain] comprises N blocks, an ith block in the first [blockchain] comprises a first field and a second field, the second field is useable to store a second preset value or a second hash value of a previous block having a block height that is the same as a block height of the ith block, and in response to i=1, the first field is useable to store a first preset value, or in response to i being greater than 1 and less than or equal to N, the first field is useable to store a first hash value of a previous block having a block height that is different from the block height of the ith block, wherein i is an integer ranging from 1 to N, the first hash value is obtained according to a first hash function, same output information is obtained according to the first hash function under a first condition based on different input information, the second hash value is a hash value obtained according to a second hash function, and same output information fails to be obtained according to the second hash function under the first condition based on different input information.”, which is “managing personal behavior or relationships or interactions between people” within the “certain methods of organizing human activity” and “Mental processes” of grouping of abstract ideas in prong one of step 2A of the Alice/Mayo test (See MPEP 2106) because the claims involve a series of steps for processing transaction request. Accordingly, the claims recite an abstract idea.
This judicial exception is not integrated into a practical application because, when analyzed under prong two of step 2A of the Alice/Mayo test (See MPEP 2106), the additional element(s) of the claim(s) such as the use of node, blockchain, processor and memory merely use(s) a computer as a tool to perform an abstract idea. The processor and memory are recited at a high-level of generality (i.e., as a generic processor performing a generic computer function of processing transaction request) such that it amounts no more than mere instructions to apply the exception using a generic computer components. Accordingly, the additional elements do not impose any meaningful limits on practicing the abstract idea, and the claims are directed to an abstract idea.
The claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to integration of the abstract idea into a practical application, the additional element of using node, blockchain, processor and memory to process transaction request steps amounts to no more than mere instructions to apply the exception using a generic computer components. Mere instructions to apply an exception using a generic computer components cannot provide an inventive concept. The claim is not patent eligible.
Dependent claims 2 and 14 describe the first hash function. Dependent claims 3 and 15 describe the second message. Dependent claims 4 and 16 describe the first block. Dependent claims 5 and 17 describe the accumulator. Dependent claims 6 and 18 describe the transaction information and a witness. Dependent claims 7 and 19 describe the simplified witness. These claims further recite the abstract idea of certain methods of organizing human activity and Mental processes. This judicial exception is not integrated into a practical application because the additional element(s) of the claim(s) such as the use of node, blockchain, processor and memory merely use(s) a computer as a tool to perform an abstract idea. The claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception. The claims are not patent eligible.
Viewed as a whole, the combination of elements recited in the claims simply recite the concept of processing transaction request. The claims do not, for example, purport to improve the functioning of the computer itself. Nor do they effect an improvement in any other technology or technical field.
The use of a node, blockchain, processor and memory as tools to implement the abstract idea does not render the claim patent eligible because it does not provide meaningful limitations beyond generally linking the use of an abstract idea to a particular technological environment and requires no more than a computer performing functions that correspond to acts required to carry out the abstract idea.
Claim Rejections - 35 USC §102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

(¶0029)
Allowable Subject Matter
Claims 5-7 and 17-19 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 101 set forth in this Office action and if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The reason for allowance will be furnished upon allowance of the application.
Conclusion
The following prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
CN111639935A (“Wei et al.”) discloses a blockchain ledger modification method. The method mainly includes: improving the chameleon hash algorithm, and the improved algorithm allows multiple nodes to jointly generate the chameleon hash public and private keys ;Using the improved chameleon hash algorithm to replace the original hash function of the blockchain, thus realizing transaction modification and verification without affecting the integrity verification of the forward and backward blocks of the corresponding high-level blockchain ledger. Removed functionality; improved usability and accountability of editable blockchain systems in some special cases. The modification scheme of the present invention has the advantages of better block compression rate, faster block modification speed and higher security, etc., and is compatible with most existing blockchain systems on the market.
CN112541195B (“Ding et al.”) discloses a method and device for constructing an editable blockchain, in which a public key of a blockchain regulator is generated according to a bilinear mapping, and transaction information is recorded in each generated block, and each block is arranged in a chain according to the generation time to form a chain editable blockchain. Since the block check field is added in the embodiment of the present invention relative to the existing chain blockchain structure, when a block needs to be re-edited, it is not necessary to re-edit all blockchains after the block, thereby reducing the amount of calculation, and the editable blockchain structure provided in the embodiment of the present invention mainly relies on the public key of the blockchain regulator, so there is no problem of secret key leakage, and security is improved. Since the embodiment of the present invention still adopts a general chain blockchain structure, the embodiment of the present invention provides a general editable blockchain structure, which can reduce the amount of calculation, improve security, and meet the editing requirements of multiple scenarios and multiple fine-grained levels
