Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claim 1 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 1 recites the limitation of “providing power to the N charging piles based on the generated operation scheduling scheme.” The specification teaches to supply power to charging piles within a period of high electricity demand; and within a period of low electricity demand, redundant power of the photovoltaic power generation system and the hydrogen power generation system is stored in the energy storage system or sold to a power grid to obtain extra earnings (Paragraph 0004). However, the specification when examined as a whole does not disclose wherein the power is supplied based on the scheduling scheme.
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.
The term "setting a number of excellent wolf individuals" in claim 1 is a relative term which renders the claim indefinite. The term "excellent" is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. For examination purposes the term “excellent” is not considered.
Response to Arguments
Applicant's arguments filed 06/12/2026 (related to the 101 Rejection) have been fully considered but they are not persuasive.
Applicant states, on pages 10-12, that the claim of the present application is directed to a specific method of generating operation scheduling scheme of a hydrogen-photovoltaic-storage-charging integrated energy station to improve efficiency and speed for quickly obtaining the optimal strategy. The claim does not merely recite the abstract idea of using mathematical equations because the claim applied such specific method to improve efficiency and speed of the result.
Second, even if the claim were to cite such an abstract idea, the amended claim integrates the abstract idea into a practical application. The added limitations specify that the initial wolf population size is optimized based on optimized parameters according to curve type and noise level of the first predation benefit curve and the optimized initial wolf population size is used in subsequent steps of the iterative solving process to obtain the optimal operation scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station. The resulting optimal operation scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station is used to control and dynamically distribute power to the N charging piles of the energy station. Consequently, efficiency and speed are improved when finding the optimal operation scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station used to manage the charging and power supply of the energy station (see paragraph [0020] of the present application). Thus, any alleged mathematical concepts are now integrated into a practical application of generating an optimal operation scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station and providing power to charging piles of the hydrogen-photovoltaic-storage-charging integrated energy station based on the optimal operation scheduling scheme under Step 2A, Prong Two, of the Alice-type §101 analysis. See MPEP §2106.04(d).
Third, even if the claim is not eligible under Step 2A, the claim is still analyzed under Step 2B to determine whether it adds "significantly more" beyond the abstract idea. To deny eligibility under this step, the Patent Office must prove that the additional limitations merely define a conventional, routine, and well-known activity under Berkheimer. The added clarifications of the steps in the claim are not a conventional, routine or well-known activity. For example, none of the references of record disclose optimized initial sizes is calculated based on Equation 5, which is then used in the subsequent steps of the iterative solving process based on the optimized parameters according to the curve type and the noise level of the first predation benefit curve obtained in Step 3.1 .4. Such limitations are unique to optimize the power generation and charging of the hydrogen-photovoltaic-storage-charging integrated energy station. For at least such reasons, the limitations add "significantly more" under Step 2B. See MPEP §2106.05.
Examiner respectfully disagrees with Applicant. In this case, these claim elements are considered to be abstract ideas because they are directed to “mathematical concepts” which include “mathematical calculations.” In this case, using an algorithm for generating a scheduling scheme encompasses a mathematical calculation. If a claim limitation, under its broadest reasonable interpretation, covers mathematical calculations, then it falls within the “mathematical concepts” grouping of abstract ideas. Accordingly, the claim recites an abstract idea.
The main functions of the additional elements recited in claim 1 are merely used for: collecting data (e.g. parameters of the charging piles and constraints of the operations), analyzing the data (e.g. solving the operation scheduling model using an improved gray wolf optimization algorithm). Those are functions that the courts have described as merely indicating a field of use or technological environment in which to apply a judicial exception (see MPEP 2106.05(h)).
Also, the grey wolf optimization algorithm is merely used for obtaining an individual position with a maximum predation benefit in a current wolf population, and outputting the individual position as an optimal scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station, wherein a specific process of iteratively solving the operation scheduling model of the hydrogen-photovoltaic-storage-charging integrated energy station comprises: Step 3.1: optimizing and improving an initial wolf population of the grey wolf optimization algorithm to obtain an ultimate initial wolf population; Step 3.2: normalizing first three wolves in the ultimate initial wolf population as a α wolf, a β wolf and a δ wolf respectively, and calculating distances from each wolf other than the α wolf, the β wolf and the δ wolf in the ultimate initial wolf population to the α wolf, the β wolf and the δ wolf; Step 3.3: updating position information, in a next iteration, of each wolf other than the α wolf, the β wolf and the δ wolf in the ultimate initial wolf population; Step 3.4: sequentially substituting the position information of all the wolves in the ultimate initial wolf population output in Step 3.3 into the operation scheduling model of the hydrogen-photovoltaic-storage-charging integrated energy station for calculation to obtain predation benefits of all the wolves in the ultimate initial wolf population; and the selecting the position information of the wolf with the maximum predation benefit in the ultimate initial wolf population as the optimal operation scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station (Paragraphs 0029-0039). Equation 5 is merely used for calculating a size s of the ultimate initial population (Paragraphs 0020-0021). Merely stating that the step is performed by an algorithm/formula results in “apply it” on a computer (MPEP 2106.05f).
Further, the step of “dynamically calculating size s and using optimized size in subsequent steps of the iterative process” is considered a well-understood, routine, and conventional function since it's just “performing repetitive calculations” (MPEP 2106.05(d)). Although the last step of claim 1 recites providing power to the N charging piles of the charging station, claim 1 lacked details as to how the system/computer is controlling the power provided to the charging piles (MPEP 2106.05f). Therefore, the last step does not integrate a judicial exception into a practical application or provide significantly more because this type of recitation is equivalent to the words “apply it.”
Claim 1 fails to recite any improvements to another technology or technical field, improvements to the functioning of the computer itself, use of a particular machine, effecting a transformation or reduction of a particular article to a different state or thing, adding unconventional steps that confine the claim to a particular useful application, and/or meaningful limitations beyond generally linking the use of an abstract idea to a particular environment. See 84 Fed. Reg. 55. Viewed individually or as a whole, these additional claim elements do not provide meaningful limitations to transform the abstract idea into a patent eligible application of the abstract idea such that the claim amounts to significantly more than the abstract idea itself. Therefore, the claim is not patent eligible.
Examiner recommends to further specify how the system is controlling the power provided to the charging piles, if supported by the specification.
Applicant's arguments filed 06/12/2026 (related to the 103 Rejection) have been fully considered and are persuasive. The combination of Liu, Ren, and Dong does not teach or suggest calculating the optimized initial population sizes (i.e., the ultimate initial population size) using Equation 5 of the present application. Size s is dynamically calculated based on the optimized parameters Zl, Z2, Z3, and Z4, which are themselves calculated based on the curve type and noise level obtained in Step 3.1.4 (see Step 3.1.4 and 3.1.5 of the present application). This calculated optimized size is then used in subsequent steps of the iterative process. The calculated sis the upper boundary limit for the initial population size of grey wolf (see Step 3.2 and Equation 6 of the present application, j is greater or equal to 4 and less than or equal to s), thereby solving the problem of low iterative solving speed caused by an excessively large initial wolf population of the existing grey wolf optimization algorithm (see paragraph [0020] of the present application). For example, the present application achieves a processing speed of 58 seconds, compared to 142 seconds when the present application is not used (see paragraph [0040] of the present application). Therefore, claim 1 has potential allowable subject matter.
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.
Claim 1 is rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e., an abstract idea) without reciting significantly more.

D.sub.δ(j) is a distance from the j.sup.th wolf in the ultimate initial wolf population to the δ wolf; X.sub.α(r), X.sub.β(r) and X.sub.δ(r) are respectively position information of the α wolf, the β wolf and the δ wolf; X.sub.j(r) is position information of the j.sup.th wolf; C.sub.α, C.sub.β and C.sub.δ are distance coefficients of the α wolf, the β wolf and the δ wolf respectively; U.sub.α,1, U.sub.β,1 and U.sub.δ,1 are random numbers which are randomly generated within [0,1] and distributed uniformly; Step 3.3: updating position information, in a next iteration, of each wolf other than the α wolf, the β wolf and the δ wolf in the ultimate initial wolf population according to formulat (7): in formula (7), X.sub.j(r+1) is the position information of the j.sup.th wolf in the next iteration;

and the selecting the position information of the wolf with the maximum predation benefit in the ultimate initial wolf population as the optimal operation scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station; Step 4: providing power to the N charging piles based on the generated operation scheduling scheme. These claim elements are considered to be abstract ideas because they are directed to “mathematical concepts” which include “mathematical calculations.” In this case, using an algorithm for generating a scheduling scheme encompasses a mathematical calculation. If a claim limitation, under its broadest reasonable interpretation, covers mathematical calculations, then it falls within the “mathematical concepts” grouping of abstract ideas. Accordingly, the claim recites an abstract idea.
Step 2A Prong 2 - The judicial exception is not integrated into a practical application. Claim 1 includes additional elements: a hydrogen-photovoltaic-storage-charging integrated energy station; and an improved grey wolf optimization algorithm.
The hydrogen-photovoltaic-storage-charging integrated energy station is a small microgrid formed by a power supply and distribution system, an energy storage system, a photovoltaic power generation system, a hydrogen power generation system and a charging system. In such a microgrid, the energy storage system, the photovoltaic power generation system and the hydrogen power generation system work together to supply power to charging piles within a period of high electricity demand; and within a period of low electricity demand, redundant power of the photovoltaic power generation system and the hydrogen power generation system is stored in the energy storage system or sold to a power grid to obtain extra earnings (Paragraph 0004). The grey wolf optimization algorithm is merely used for obtaining an individual position with a maximum predation benefit in a current wolf population, and outputting the individual position as an optimal scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station, wherein a specific process of iteratively solving the operation scheduling model of the hydrogen-photovoltaic-storage-charging integrated energy station comprises: Step 3.1: optimizing and improving an initial wolf population of the grey wolf optimization algorithm to obtain an ultimate initial wolf population; Step 3.2: normalizing first three wolves in the ultimate initial wolf population as a α wolf, a β wolf and a δ wolf respectively, and calculating distances from each wolf other than the α wolf, the β wolf and the δ wolf in the ultimate initial wolf population to the α wolf, the β wolf and the δ wolf; Step 3.3: updating position information, in a next iteration, of each wolf other than the α wolf, the β wolf and the δ wolf in the ultimate initial wolf population; Step 3.4: sequentially substituting the position information of all the wolves in the ultimate initial wolf population output in Step 3.3 into the operation scheduling model of the hydrogen-photovoltaic-storage-charging integrated energy station for calculation to obtain predation benefits of all the wolves in the ultimate initial wolf population; and the selecting the position information of the wolf with the maximum predation benefit in the ultimate initial wolf population as the optimal operation scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station (Paragraphs 0029-0039). Equation 5 is merely used for calculating a size s of the ultimate initial population (Paragraphs 0020-0021). Merely stating that the step is performed by an algorithm/equation results in “apply it” on a computer (MPEP 2106.05f). These elements of “hydrogen-photovoltaic-storage-charging integrated energy station” and “grey wolf optimization algorithm” are recited at a high level of generality such that it amounts no more than mere instructions to apply the exception using a generic computer element. Accordingly, alone and in combination, these additional elements do not integrate the abstract idea into a practical application because they do not impose any meaningful limits on practicing the abstract idea. Therefore, the claim is directed to an abstract idea.
Step 2B - The claim does not include additional elements that are sufficient to amount significantly more than the judicial exception. As discussed above with respect to integration of the abstract idea into a practical application, the claims describe how to generally “apply” the concept of solving an optimization problem. The specification shows that the hydrogen-photovoltaic-storage-charging integrated energy station is a small microgrid formed by a power supply and distribution system, an energy storage system, a photovoltaic power generation system, a hydrogen power generation system and a charging system. In such a microgrid, the energy storage system, the photovoltaic power generation system and the hydrogen power generation system work together to supply power to charging piles within a period of high electricity demand; and within a period of low electricity demand, redundant power of the photovoltaic power generation system and the hydrogen power generation system is stored in the energy storage system or sold to a power grid to obtain extra earnings (Paragraph 0004). The grey wolf optimization algorithm is merely used for obtaining an individual position with a maximum predation benefit in a current wolf population, and outputting the individual position as an optimal scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station, wherein a specific process of iteratively solving the operation scheduling model of the hydrogen-photovoltaic-storage-charging integrated energy station comprises: Step 3.1: optimizing and improving an initial wolf population of the grey wolf optimization algorithm to obtain an ultimate initial wolf population; Step 3.2: normalizing first three wolves in the ultimate initial wolf population as a α wolf, a β wolf and a δ wolf respectively, and calculating distances from each wolf other than the α wolf, the β wolf and the δ wolf in the ultimate initial wolf population to the α wolf, the β wolf and the δ wolf; Step 3.3: updating position information, in a next iteration, of each wolf other than the α wolf, the β wolf and the δ wolf in the ultimate initial wolf population; Step 3.4: sequentially substituting the position information of all the wolves in the ultimate initial wolf population output in Step 3.3 into the operation scheduling model of the hydrogen-photovoltaic-storage-charging integrated energy station for calculation to obtain predation benefits of all the wolves in the ultimate initial wolf population; and the selecting the position information of the wolf with the maximum predation benefit in the ultimate initial wolf population as the optimal operation scheduling scheme of the hydrogen-photovoltaic-storage-charging integrated energy station (Paragraphs 0029-0039). Equation 5 is merely used for calculating a size s of the ultimate initial population (Paragraphs 0020-0021). Also, the step of “iteratively solving” is considered a well-understood, routine, and conventional function since it's just “performing repetitive calculations” (MPEP 2106.05(d)). Although the last step of claim 1 recites providing power to the N charging piles of the charging station, claim 1 lacked details as to how the system/computer is controlling the power provided to the charging piles (MPEP 2106.05f). Thus, nothing in the claim adds significantly more to the abstract idea. The claim is ineligible.

An improved grey wolf optimizer (IGWO) with evolution and elimination mechanism was proposed so as to achieve the proper compromise between exploration and exploitation, further accelerate the convergence and increase the optimization accuracy of GWO. The biological evolution and the "survival of the fittest" (SOF) principle of biological updating of nature are added to the basic wolf algorithm. The differential evolution (DE) is adopted as the evolutionary pattern of wolves. The wolf pack is updated according to the SOF principle so as to make the algorithm not fall into the local optimum. That is, after each iteration of the algorithm sort the fitness value that corresponds to each wolf by ascending order, and then eliminate R wolves with worst fitness value, meanwhile randomly generate wolves equal to the number of eliminated wolves. Finally, 12 typical benchmark functions are used to carry out simulation experiments with GWO with differential evolution (DGWO), GWO algorithm with SOF mechanism (SGWO), IGWO, DE algorithm, particle swarm algorithm (PSO), artificial bee colony (ABC) algorithm and cuckoo search (CS) algorithm. Experimental results show that IGWO obtains the better convergence velocity and optimization accuracy).

Khalid et al. (US 2024/0119281 A1) – discloses renewable energy is one of the fastest growing energy technologies, and in particular, solar energy is preferred as it helps to generate power cost effectively and with zero carbon emissions. However, the inherent intermittent nature of solar power due to variations in the sunlight, e.g., caused by moving clouds, makes it a challenge to dispatch uninterrupted power into grid. The resultant fluctuating power can cause various problems in the grid such as frequency deviations, voltage hindrances, and excessive peak loads which ultimately would lead to electricity blackouts or power outages in the grids. Therefore, to encourage the delivery of large-scale solar power into the grid, solar photovoltaic (PV) power output needs to be smoothed out before it can be dispatched into the grid in a controlled manner. An energy storage system (ESS) can be integrated with the renewable energy (RE) resources for power supply regulation, management, and optimal operation. In particular, a battery energy storage system (BESS) can be integrated with the RE systems to produce promising results. The BESS can be integrated with the solar PV to mitigate the issue of the fluctuating solar power. Improving the lifespan of the BESS while lessening the operating expenses is a well-investigated area Studies have recommended innovative supervision procedures for improving the lifetime of the BESS while determining the battery charging/discharging power (see at least Paragraph 0006).
