Office Action

§101 §102 §112
CTNF 19/140,369 CTNF 96728 Detailed Action 12-151 AIA 26-51 12-51 Status of Claims This is the first office action on the merits. Claims 1-20 are currently pending and addressed below. Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Information Disclosure Statement The information disclosure statement (IDS) submitted on 06/01/2026 has being considered by the examiner. Claim Objections 07-29-01 AIA Claim 17 is objected to because of the following informalities: Claim 17 states “ …wherein he… ” Examiner assumes it was intended to read as “…wherein the …” . Appropriate correction is required. Specification 07-44 AIA The specification is objected to as failing to provide proper antecedent basis for the claimed subject matter. See 37 CFR 1.75(d)(1) and MPEP § 608.01(o). Correction of the following is required: Claim 1 contains language referencing a second injector however, no second injector is disclosed in the specification . Claim Rejections - 35 USC § 112 07-30-02 AIA 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. 07-34-01 Claims 1-20 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, 11, 20 The metes and bounds of claims 1, 11, 20 are ambiguous as the claim language states “a resource site” in the preamble however in limitation regarding the geo-radius the claims cite “a resource site” and it is not clear if this is a second resource site or the same resource site from the preamble. Therefore, as it is not clear that the claim language is indicating one resource site or multiple resource sites, the claim language is ambiguous in the metes and bounds of claims 1, 11, 20. Claims 1, 11, 20 are rejected on this basis. Claims 2-10, 12-19 are rejected for depending on a rejected claim. Claim 1 Claim 1 recites the limitation " the second injector " in line 5. There is insufficient antecedent basis for this limitation in the claim. Furthermore, the metes and bounds of the claim are unclear as this is the only mention of a second injector in the claims and therefore, unclear if the claim language is introducing a second injector with out antecedent basis or an unintended inclusion in the claim language. Therefore as the claim language is unclear as to intended language of the limitation regarding the second injection the metes and bounds of claim 1 are unclear. Claim 1 is rejected on these basis’ Claims 2-10 are rejected for depending on a rejected claim. Examiners note: As no further mention of a second injector is present in the claims or specification Examiner assumes for examination purposes that it is the first producer using similar claim language present in claims 11 & 20. Claim 1: … determine a correlated pair of injectors and producers associated with the first injector and the second injector Claim 11: … determine a correlated pair of injectors and producers associated with the first injector and the first producer Claim Rejections - 35 USC § 101 07-04-01 AIA 07-04 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 1-20 are rejected under 35 U.S.C. 101 because the claimed invention is directed towards an abstract idea. Step 1 of the USPTO’s eligibility analysis entails considering whether the claimed subject matter falls within the four statutory categories of patentable subject matter identified by 35 U.S.C. 101: Process, machine, manufacture, or composition of matter. Claims 1, 11, 20 are directed to a method (process) and a system (machine or manufacture) respectively. As such, the claims are directed to statutory categories of invention. If the claim recites a statutory category of invention, the claim requires further analysis in Step 2A. Step 2A of the 2019 Revised Patent SUBJECT Matter Eligibility Guidance is a two-prong inquiry. In Prong One, examiners evaluate whether the claim recites a judicial exception The claim(s) recite(s) abstract limitations including: Claim 1: determining a geo radius; correlating the fluid production rate data with the fluid in injection rate data; …determine a correlated pair…; generating a forecasting model Claims 11: determine a geo radius; correlate the fluid production rate data with the fluid injection rate data…; …determine a correlated pair…; generate a forecasting model Claim 20: determining a geo radius; correlating the fluid production rate data with the fluid injection rate data…; …determine correlated pairs…; generating a forecasting model These limitations, as drafted, are abstract mental processes that, under the broadest reasonable interpretation, cover performance of the limitations in the mind, or by a human using pen and paper, and therefore recite mental processes. More specifically, nothing in the claim element precludes the aforementioned steps from practically being performed in the human mind, or by a human using pen and paper. The mere recitation of generic computing elements and/or sensors does not take the claim out of the mental process grouping. Thus the claim recites an abstract idea. If the claim recites a judicial exception (i.e., an abstract idea enumerated in Section I of the 2019 Revised Patent Subject Matter Eligibility Guidance, a law of nature, or a natural phenomenon), the claim requires further analysis in Prong Two. In Prong Two, examiners evaluate whether the claim recites additional elements that integrate the exception into a practical application of that exception. Claims 1, 11, 20 recites the additional elements of: Claim 1: A resource site, a first injector, a first producer, a pump mechanism which merely links said method to a particular technical environment or field of use; …Using the correlated pair of injectors and producers… which are recited at a high level of generality and amount to no more than mere instructions to apply the exception. Receiving fluid production rate data, receiving fluid injection rate data, the forecasting model being parametrized using one or more of a first variable indicating a first range of fluid production rate values, a second variable indicating a second range of fluid injection rate values, executing…one or more sensitivity tests comprising at least one simulation based on the first variable or the second variable to generate a production forecast report for the first producer, initiating generation of a visualization indicating the production forecast report for viewing on a display device, initiating transmission of a pump rate control signal to configure… which are considered an insignificant extra solution activity; Claim 11: A resource site, a first injector, a first producer, a pump mechanism which merely links said method to a particular technical environment or field of use; A computer processor, memory storing instructions that are executable by the computer processor, …Using the correlated pair of injectors and producers… which are recited at a high level of generality and amount to no more than mere instructions to apply the exception. Receiving fluid production rate data, receiving fluid injection rate data, the forecasting model being parametrized using one or more of a first variable indicating a first range of fluid production rate values, a second variable indicating a second range of fluid injection rate values, executing…one or more sensitivity tests comprising at least one simulation based on the first variable or the second variable to generate a production forecast report for the first producer, initiating generation of a visualization indicating the production forecast report for viewing on a display device, and initiating transmission of a pump rate control signal to configure… which are considered an insignificant extra solution activity; Claim 20: A resource site, a first injector, a first producer, a pump mechanism which merely links said method to a particular technical environment or field of use; …Using the correlated pair of injectors and producers which are recited at a high level of generality and amount to no more than mere instructions to apply the exception. Fluid production rate data obtained from one or more sensors…, fluid injection rate data obtained from one or more sensors…, the forecasting model being parametrized using one or more of a first variable indicating a first range of fluid production rate values, a second variable indicating a second range of fluid injection rate values, executing…one or more sensitivity tests comprising at least one simulation based on the first variable or the second variable to generate a production forecast report for the first producer, initiating generation of a visualization indicating the production forecast report for viewing on a display device and initiating transmission of a pump rate control signal to configure… which are considered an insignificant extra solution activity; If the additional elements do not integrate the exception into a practical application, then the claim is directed to the recited judicial exception, and requires further analysis under Step 2B to determine whether they provide an inventive concept (i.e., whether the additional elements amount to significantly more than the exception itself). Claim 1: As discussed above, A resource site, a first injector, a first producer, a pump mechanism merely link the method to a particular environment or field of use. As they merely confine the use of the abstract idea to a particular technical field of use they fail to add an invention concept to the claim. These limitations represent mere token acquiescence to limiting the reach of the claim (see Flook and MPEP 2106.5(h)). With respect to …Using the correlated pair of injectors and producers merely amounts to “apply it”. The reciting of claim limitations that attempt to cover any solution (i.e. using data) to an identified problem (i.e. model generation) with no restriction on how the result is accomplished and no description of the mechanism for accomplishing the result (i.e. what aspects are changed or how the change is affected by the abstract idea) 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”. See MPEP 2106.05(f)(1) Regarding the recited process in the “Receiving fluid production rate data, receiving fluid injection rate data, the forecasting model being parametrized using one or more of a first variable indicating a first range of fluid production rate values, a second variable indicating a second range of fluid injection rate values, executing…one or more sensitivity tests comprising at least one simulation based on the first variable or the second variable to generate a production forecast report for the first producer, initiating generation of a visualization indicating the production forecast report for viewing on a display device, initiating transmission of a pump rate control signal to configure…” steps are considered an insignificant extra solution activity as the limitations amount to selecting a particular data source or type of data to be manipulated. As noted in Electric Power Group, selecting information, based on types of information and availability of information for collection, analysis, and display is considered insignificant extra solution activity (see MPEP 2106.05(g)). Additionally, the Symantec, TLI, OIP Techs. And buySAFE court decisions cited in MPEP 2106.05(d)(II) indicate that mere receiving or transmitting data over a network is considered insignificant extra solution activity. Claim 11: As discussed above, A resource site, a first injector, a first producer, a pump mechanism merely link the method to a particular environment or field of use. As they merely confine the use of the abstract idea to a particular technical field of use they fail to add an invention concept to the claim. These limitations represent mere token acquiescence to limiting the reach of the claim (see Flook and MPEP 2106.5(h)). With respect to A computer processor, memory storing instructions that are executable by the computer processor, these elements are recited at a high level of generality such that they amount to no more than mere instructions to apply the exception. Mere instructions to apply an exception using a generic computer component cannot provide an inventive concept. Additionally, the specification fails to disclose that these elements are anything other than generic computing elements and are even shown as black boxes on the figures. (see MPEP2106.05(f)). With respect to …Using the correlated pair of injectors and producers merely amounts to “apply it”. The reciting of claim limitations that attempt to cover any solution (i.e. using data) to an identified problem (i.e. model generation) with no restriction on how the result is accomplished and no description of the mechanism for accomplishing the result (i.e. what aspects are changed or how the change is affected by the abstract idea) 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”. See MPEP 2106.05(f)(1) Regarding the recited process in the “Receiving fluid production rate data, receiving fluid injection rate data, the forecasting model being parametrized using one or more of a first variable indicating a first range of fluid production rate values, a second variable indicating a second range of fluid injection rate values, executing…one or more sensitivity tests comprising at least one simulation based on the first variable or the second variable to generate a production forecast report for the first producer, initiating generation of a visualization indicating the production forecast report for viewing on a display device, and initiating transmission of a pump rate control signal to configure…” steps are considered an insignificant extra solution activity as the limitations amount to selecting a particular data source or type of data to be manipulated. As noted in Electric Power Group, selecting information, based on types of information and availability of information for collection, analysis, and display is considered insignificant extra solution activity (see MPEP 2106.05(g)). Additionally, the Symantec, TLI, OIP Techs. And buySAFE court decisions cited in MPEP 2106.05(d)(II) indicate that mere receiving or transmitting data over a network is considered insignificant extra solution activity. Claim 20: As discussed above, A resource site, a first injector, a first producer, a pump mechanism merely link the method to a particular environment or field of use. As they merely confine the use of the abstract idea to a particular technical field of use they fail to add an invention concept to the claim. These limitations represent mere token acquiescence to limiting the reach of the claim (see Flook and MPEP 2106.5(h)). With respect to …Using the correlated pair of injectors and producers merely amounts to “apply it”. The reciting of claim limitations that attempt to cover any solution (i.e. using data) to an identified problem (i.e. model generation) with no restriction on how the result is accomplished and no description of the mechanism for accomplishing the result (i.e. what aspects are changed or how the change is affected by the abstract idea) 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”. See MPEP 2106.05(f)(1) Additionally, one or more plurality of the sensors is recited at a high level of generality. Given the generality of the positioning of the sensors, the type of sensor, and the type of data collected by the sensors, these limitations do not contain significantly more to provide a practical application (see MPEP 2106.05(g)) Regarding the recited process in the “Fluid production rate data obtained from…, fluid injection rate data obtained from…, the forecasting model being parametrized using one or more of a first variable indicating a first range of fluid production rate values, a second variable indicating a second range of fluid injection rate values, executing…one or more sensitivity tests comprising at least one simulation based on the first variable or the second variable to generate a production forecast report for the first producer, initiating generation of a visualization indicating the production forecast report for viewing on a display device and initiating transmission of a pump rate control signal to configure…” steps are considered an insignificant extra solution activity as the limitations amount to selecting a particular data source or type of data to be manipulated. As noted in Electric Power Group, selecting information, based on types of information and availability of information for collection, analysis, and display is considered insignificant extra solution activity (see MPEP 2106.05(g)). Additionally, the Symantec, TLI, OIP Techs. And buySAFE court decisions cited in MPEP 2106.05(d)(II) indicate that mere receiving or transmitting data over a network is considered insignificant extra solution activity. Therefore, the claim does not provide an inventive concept (significantly more than the abstract idea). The claim is ineligible. Thus, even when viewed as an ordered combination, nothing in the claims add significantly more (i.e., an inventive concept) to the abstract idea. The various metrics of claims 2-10, 12-19 merely narrow the recitation of the specific variables and data limitations are insufficient as “merely selecting information, by content or source, for collection, analysis, and display does nothing significant to differentiate a process from ordinary mental processes, whose implicit exclusion from §101 undergirds the information-based category of abstract ideas," (See Electric Power Group, LLC v. Alstom, S.A., 830 F.3d 1350, 1355 (Fed. Cir. 2016)). Similar to claim 1, 13 and 18 this recitation does not provide a practical application of the abstract idea, and is not significantly more.

A method for water flooding optimization (Champenoy [0006] methods and systems for water flood optimization) at a resource site for increased production of hydrocarbons (Champenoy [0004] water flood is a known technique for enhanced oil recovery (EOR)), the method comprising: determining a geo-radius (Champenoy Fig 2a, 2b, 2c [0032] circular regions associated with injector wells) circumscribing one or more injectors (Champenoy fig 2a; injector well 10a [0032] injector well 10a) and one or more producers (Champenoy [0032] producer to injector connectivity) at a resource site (Champenoy [0028] individual injector regions at a reservoir); receiving: fluid production rate data (Champenoy [0031] input of production, time period and flowing bottom hole pressure data) obtained from one or more sensors (Champenoy [0031] input of production, time period and flowing bottom hole pressure data) disposed about the one or more producers at the resource site (Champenoy [0031] input of production, time period and flowing bottom hole pressure data collected around the reservoir and well sites), and fluid injection rate data (Champenoy [0031] input of injection, time period and flowing bottom hole pressure data) obtained from one or more sensors (Champenoy [0031] input of injection, time period and flowing bottom hole pressure data collected around the reservoir and well sites) disposed about the one or more injectors at the resource site (Champenoy [0031] input of injection, time period and flowing bottom hole pressure data collected around the reservoir and well sites); correlating the fluid production rate data with the fluid injection rate data to determine correlated pairs of injectors and producers associated with the one or more injectors and the one or more producers (Champenoy [0034] Water injection influence map takes the water injection data of a region from the injector wells and correlates it to the water influence on producer wells), the correlated pairs of injectors and producers indicating a relationship between a first injector comprised in the one or more injectors and a first producer comprised in the one or more producers (Champenoy [0034] Water injection influence map takes the water injection data of a region from the injector wells and correlates it to the water influence on producer wells); generating a forecasting model using the correlated pairs of injectors and producers (Champenoy Fig 10 [0043] shows a plot of water injection volume, produced oil volume and produced water volume and determining the impact of two new wells utilizing curve approve estimation and Fig 11 [0044] Voidage replacement ratio (VRR) predictions based on historical data), the forecasting model being parameterized using one or more of: a first variable (Champenoy Fig 1; S10 [0031] input of production, time period and flowing bottom hole pressure data) indicating a first range of fluid production rate values (Champenoy [0034] producer wells have multiple values of water influence), and a second variable (Champenoy Fig 1; S10 [0031] input of injection, time period and flowing bottom hole pressure data) indicating a second range of fluid injection rate values (Champenoy [0034] injection volume and individual injection influence data); executing using the forecasting model, one or more sensitivity tests comprising at least one simulation based on the first variable or the second variable to generate a production forecast report for the first producer (Champenoy Fig 1; S28 [0038] predicting and developing a plan to maintain VRR target); and executing one or more of: initiating generation of a visualization indicating the production forecast report for viewing on a display device (Chapenoy Fig 10 [0043] showing a plot with predicted production values) Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Sun (US Pub No 20220147674): Sun teaches the development of a fluid dynamics model for flood optimization for oil recovery utilizing predictive methodologies and historical data. Optimization relies on modification of injection rates to production rates from injector and producer wells. See Figs 1-3 and Fig 9-10 and para [0041], [0051]-[0057] for details.
