Specification
The specification is objected to because it contains an embedded hyperlink and/or other form of browser-executable code at [34:6] and [34:21]. Applicant is required to delete the embedded hyperlink and/or other form of browser-executable code; references to websites should be limited to the top-level domain name without any prefix such as http:// or other browser-executable code. See MPEP § 608.01.
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.
Claims 4, 8, and 20 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, regards as the invention.
In claim 4, the recited " the presence of an infection", "the presence of malignancy", "the presence of anemia", and "the presence of diabetes" require but lack clear antecedents. If these recitations refer to previously instantiated instances, then it is not clear which instances they are. If these recitations instantiate these claim elements, this is not clear. This rejection might be overcome by for example amending to recite the article "a" instead of "the" or an equivalent amendment, such as deleting "the." For compact examination, it is assumed that the preceding suggestion will be implemented.
In claim 8, the recited "the expression" requires but lacks clear antecedent. If this recitation refers to a previously instantiated instance, then it is not clear which instance that is. If this recitation instantiates this claim element, this is not clear. This rejection might be overcome by for example amending to recite the article "a" instead of "the" or an equivalent amendment. For compact examination, it is assumed that the preceding suggestion will be implemented.
In claim 20, the recited "the equation" requires but lacks clear antecedent. If this recitation refers to a previously instantiated instance, then it is not clear which instance that is. If this recitation instantiates this claim element, this is not clear. This rejection might be overcome by for example amending to recite the article "a" instead of "the" or an equivalent amendment. For compact examination, it is assumed that the preceding suggestion will be implemented.
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 1-26 are rejected under 35 U.S.C. 101 because the claimed invention is directed to one or more judicial exceptions without significantly more.
MPEP 2106 details the following framework to analyze Subject Matter Eligibility:
• Step 1: Are the claims directed to a category of statutory subject matter (a process, machine, manufacture, or composition of matter)? (see MPEP § 2106.03)
• Step 2A, Prong One: Do the claims recite a judicially recognized exception, i.e. an abstract idea, a law of nature, or a natural phenomenon? (see MPEP § 2106.04(a)). Note, the MPEP at 2106.04(a)(2) & 2106.04(b) further explains that abstract ideas and laws of nature are defined as:
• mathematical concepts, (mathematical formulas or equations, mathematical
relationships and mathematical calculations);
• certain methods of organizing human activity (fundamental economic practices
or principles, managing personal behavior or relationships or interactions between
people); and/or
• mental processes (procedures for observing, evaluating, analyzing/ judging and
organizing information).
• laws of nature and natural phenomena are naturally occurring principles/ relations that
are naturally occurring or that do not have markedly different characteristics compared to
what occurs in nature.
• Step 2A, Prong Two: If the claims recite a judicial exception under Prong One, then is the judicial exception integrated into a practical application? (see MPEP § 2106.04(d))
• Step 2B: If the claims do not integrate the judicial exception, do the claims provide an inventive concept? (see MPEP § 2106.05)
Regarding Step 1: Yes, claims 1-26 are directed to a related method, system, and non-transitory computer-readable storage medium, and therefore to a category of statutory subject matter. (See MPEP § 2106.03)
Regarding Step 2A, Prong One: The claims recite judicial exceptions of abstract ideas of mathematical concepts and mental processes as follows:
• Calculating parameter(s) (recited in claims 1, 13, -15, 25, and 26.)
• Determining a pathophysiological state based on the parameters (recited in claims 1, 13, 14.)
• Determining an RBC clearance rate, production rate, or age distribution (recited in claim 2.)
• Determining a rate of change in white blood cell count, a rate of change in platelet count, a rate of blood loss, or a rate of bone marrow cellular output (recited in claim 3.)
• Determining information indicative of a degree of morbidity (recited in claim 4.)
• Claims 5, 6, 17, and 18 further limit the parameters of claims 1 or 15.
• Calculating a probability density (recited in claims 7 and 19.)
• The expression for the probability density as a function of time in claims 8 and 20.
• Calculating an RBC age distribution (recited in claims 9 and 21.)
• Determining a HbA1c level indicative of diabetes or prediabetes by adjusting a nominal HbA1c level based on the RBC age distribution (recited in claim 10, 11, 22, and 23.)
To summarize, the claims recite judicial exceptions in abstract ideas, characterized as mathematical concepts and mental processes. Considering the broadest reasonable interpretation (BRI) of the claims, the mental processes recited in independent claim 1 (e.g., calculating parameters, determining a pathophysiological state, determining rates of change, calculating probability densities, etc.) are directed to processes that may be performed in the human mind, or with pen and paper, because there are no particular limitations recited in the claims which would prevent performance in the human mind or with pen and paper. Additionally, the claims recite mathematical concepts; explicitly in the calculating recitations, as well as implicitly in the determining of states, rates, or levels; the mathematical concepts are disclosed in the Specification [3:10-19], [13:22-15:7], [17:3-19:16], etc. Such analysis performed mentally, or with paper and pencil, may take considerable time and effort, and although a general-purpose computer can perform these calculations at a rate and accuracy that can far exceed the mental performance of a skilled artisan, the nature of the activity is essentially the same, and therefore constitutes an abstract idea.
Therefore, claims 1-26 recite elements that constitute a judicial exception in the form of abstract ideas. (Step 2A, Prong One: Yes.)'
Regarding the Step 2A, Prong Two: Because claims 1-26 have been interpreted as being directed to judicial exceptions, abstract ideas in this instance, then Step 2A, Prong Two provides that the claims be examined further to determine whether they integrate the abstract ideas into a practical application. A claim can be said to integrate a judicial exception into a practical application when it applies, relies on, or uses the judicial exception in a manner that imposes a meaningful limit on the judicial exception. The Step 2A, Prong Two analysis is performed in order to determine if the abstract idea is integrated into a practical application [see MPEP § 2106.04(d) and (d)(I)] by analyzing the additional elements of the claim, alone or in combination, for the following considerations:
• an improvement to technology [see MPEP 2106.04(d) & (d)(1); and 2106.05(a)]
• a particular therapy/prophylaxis [see MPEP 2106.04(d) & (d)(2); and 2106.05(e)]
• a particular machine [see MPEP 2106.04(d) and 2106.05(b)]
• a particular transformation [see MPEP 2106.04(d) and 2106.05(c)]
• or for applying or using the judicial exception in some other meaningful way beyond generally linking the use of the judicial exception to a particular technological environment [see MPEP 2106.04(d) and 2106.05(e)].
The claims recite additional elements as follows:
Additional elements of data gathering: Claims 1, 10, 11, 13-15, 22-23, 25, and 26 recite the additional element of "receiving data." Data gathering steps are additional elements which perform functions of inputting, collecting, and outputting the data needed to carry out the abstract idea. These steps are considered insignificant extra-solution activity, and are not sufficient to integrate an abstract idea into a practical application as they do not impose any meaningful limitation on the abstract idea or how it is performed, nor do they provide an improvement to technology [see MPEP § 2106.04(d)(I)].
Additional element of therapy: Claims 10, 11, 22, and 23 recite "administering or adjusting treatment for diabetes or prediabetes"; claims 12 and 24 recite "administering a dose of iron supplementation"; claim 15 recites " administering treatment to the subject for a morbidity." The claims do not yet recite a particular therapy as the claims lack a level of specificity for the treatment (claims 10, 11, 22, and 23), for the disease (claims 12 and 24), and for both treatment and disease (claim 15). As such, the treatment limitations in claims 10-12, 15, and 22-24 are not elevated to a particular treatment, and therefore are insufficient to integrate the abstract ideas into a practical application (see MPEP § 2106.04(d)(2)).
Note, regarding the therapy steps of "method" claims 10, 12, 15, 22, and 24, when a physical step such as "administering..." or "adjusting..." is recited as contingent, then it is only interpreted as an additional element for embodiments in which the contingency is true and the step actually is required. This interpretation applies to process claims. Machine or manufacture claims requiring equivalent process instructions, on the other hand, still require the result of the contingency be provided for in the structure of the claim, e.g. in instructions, regardless of the eventual evaluation of the contingency.
Additional elements of computer components: Claims 13, 14, 25, and 26 recite the additional elements of "processor(s)", "memory", and/or "non-transitory computer-readable storage medium (CRM)." The claims require only generic computer components, which do not improve computer technology, and do not integrate the recited judicial exception into a practical application (see MPEP § 2106.04(d)(1) and MPEP § 2106.05(f)).
Step 2A Prong Two summary: Claims 1-26 have been further analyzed with respect to Step 2A, Prong Two, and no additional elements have been found, alone or in combination, that would integrate the judicial exception into a practical application. (Step 2A, Prong Two: No).
Step 2B analysis: Because the additional claim elements do not integrate the judicial exception of abstract ideas into a practical application, claims 1-26 are further examined under Step 2B, which evaluates whether the additional elements, individually and in combination, amount to significantly more than the judicial exception itself by providing an inventive concept. An inventive concept is furnished by an element or combination of elements that is recited in the claim in addition to the judicial exception, and is sufficient to ensure that the claim, as a whole, amounts to significantly more than the judicial exception itself (see MPEP § 2106.05).
The claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the claims recite additional elements that are well-understood, routine, and conventional. Those additional elements are as follows:
Additional elements of data gathering, inputting, and outputting steps: The additional elements of receiving data (claims 1, 10, 11, 13-15, 22-23, 25, and 26), do not cause the claims to rise to the level of significantly more than the judicial exception. The courts have recognized receiving or transmitting data over a network; storing and retrieving information in memory; determining the level of a biomarker in blood by any means; [see MPEP§2106.05(d)(II)], as well-understood, routine, conventional activity when they are claimed in a merely generic manner (e.g., at a high level of generality) or as extra-solution activity. Therefore the additional elements of data gathering are routine, well-understood, and conventional, and do not provide an inventive concept needed to amount to significantly more than the judicial exception.
Additional elements of treatment: Claims 10, 11, 22, and 23 recite "administering or adjusting treatment for diabetes or prediabetes"; claims 12 and 24 recite "administering a dose of iron supplementation"; claim 15 recites " administering treatment to the subject for a morbidity." These additional elements are shown to be well-known, routine, and conventional in the art as follows:
Chaudhury, (Clinical review of antidiabetic drugs: implications for type 2 diabetes mellitus management. Frontiers in endocrinology, vol. 8:6, pages 1-12; cited on the attached PTO-892), discusses the pharmacologic management of Type 2 Diabetes (T2D) (p.3-10, and throughout document); HbA1C level in diagnosing, monitoring, adjusting management of T2D (p.2-3; p.4, col.1).
Wang, (Iron deficiency and other types of anemia in infants and children. American family physician, vol. 93(4), pages 270-278 (2016); cited on the attached PTO-892), discusses iron supplementation and differential diagnosis of anemia (p.272-274 , text; p.273, tables 3&4.)
Additional elements of computer components: The additional elements of processor(s), memory, and/or non-transitory CRM of claims 13, 14, 25, and 26, do not cause the claims to rise to the level of significantly more than the judicial exception; these are conventional computer components and as such do not provide an inventive concept.
Further regarding the conventionality of additional elements, the MPEP at 2106.05(b) and 2106.05(d) presents several points relevant to conventional computers and data gathering steps in regard to Step 2A Prong 2 and Step 2B, including:
• A general purpose computer that applies a judicial exception, such as an abstract idea, by use of conventional computer functions, does not qualify as a particular machine (see 2106.05(b)(I)), as in the case of claim 13, 14, 25, and 26, which are interpreted to recite conventional computer components.
• Integral use of a machine to achieve performance of a method may integrate the recited judicial exception into a practical application or provide significantly more, in contrast to where the machine is merely an object on which the method operates, which does not integrate the exception into a practical application or provide significantly more (see 2106.05(b)(II). In instant claims 13, 14, 25, and 26, the recited processors, memory, and CRM are used in receiving and calculating, etc.; as such, they act only as tools to perform the steps of calculating, and do not integrate the judicial exception into a practical application or provide significantly more.
• Use of a machine that contributes only nominally or insignificantly to the execution of the claimed method (e.g., in a data gathering step or in a field-of-use limitation) would not integrate a judicial exception or provide significantly more (see 2106.05(b)(III). The processors, memory, and CRM of claim 13, 14, 25, and 26 used in receiving and calculating do not impose meaningful limitations on the claims.
• The courts have recognized “receiving or transmitting data over a network”, “performing repetitive calculations”, and “storing and retrieving information in memory”, as well-understood, routine, and conventional functions when they are claimed in a merely generic manner (e.g., at a high level of generality) or as insignificant extra-solution activity (see MPEP 2106.05(d)(II)). The receiving of data in claims 1, 10, 11, 13-15, 22-23, 25, and 26 is recited in a generic manner.
All limitations of claims 1-26 have been analyzed with respect to Step 2B, and none provides a specific inventive concept, as they all fail to rise to the level of significantly more than the identified judicial exception, and thus do not transform the judicial exception into a patent eligible application of the exceptions. Step2B: NO. Therefore, claims 1-26, when the limitations are considered individually and as a whole, are rejected under 35 U.S.C. § 101 as being directed to non-statutory subject matter.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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 1-26 are rejected under 35 U.S.C. 103 as being unpatentable over Golub, (American journal of hematology, vol. 89(5), pages 459-466 (2014); cited on the 10/05/2022 IDS), in view of Patel, (American journal of hematology, vol. 90(5), pages 422-428 (2015); cited on the 10/05/2022 IDS.)
Regarding the claim 1, 13-15, 25, and 26 steps for "receiving data" of a first and a second CBC, including RBC volume and hemoglobin and Golub teaches obtaining blood samples from rhesus macaque infants at birth, 4, 6, 12, and 22.5 months, and performing complete blood count (CBC) to obtain distributions of single-RBC and single reticulocyte volume and hemoglobin concentration (p.460, col.1).
Regarding the claim 1, 13-15, 25, and 26 step for "calculating…parameters …based on volume and hemoglobin, the …parameters including …a rate of change in RBC clearance rate …or rate of change in RBC production rate", Golub teaches RBC population dynamics for monkeys and humans were modeled using single-cell measurements of RBC volume and hemoglobin concentration and a published mathematical model (p.460, col.1). Golub teaches "the model (eq. (1)) describes the volume and hemoglobin dynamics of a typical RBC (dv/dt, dh/dt) as a function (f) of its current volume and hemoglobin and accounting for fluctuations in these rates over time (n). The dynamics of the full RBC population dP/dt include production of reticulocytes (b) and clearance of senescent cells (c) (p.462, col.1.)
Regarding the claim 1, 13-15, 25, and 26 step for " a pathophysiological state …", Golub, at p.463, cols.1-2, teaches finding "a significant difference in the RBC clearance threshold (vc) (in Fig. 2G, p.462.) The detailed mechanism for RBC clearance in general is not well understood and is unlikely to be determined by volume or hemoglobin content alone, but because the clearance signal is highly correlated with these quantities, comparisons are made of empirical clearance thresholds between the groups in terms of volume and hemoglobin content. … (the study) finds that RBCs in iron deficient (ID) animals continue to circulate at significantly lower volumes and hemoglobin contents than in iron sufficient (IS) animals, even after normalizing for the lower MCV and MCH in the ID cohort. In IS animals, most RBCs have been removed before their volume reaches 77% of the animal’s MCV, while in ID animals the clearance threshold is lower, and cells continue to mature and circulate beyond this point (p.463, cols.1-2.)
Regarding the claim 2 recitation for " determining… a RBC clearance rate, a RBC production rate, or a RBC age distribution", Golub teaches the dynamics of the full RBC population dP/dt include production of reticulocytes (b) and clearance of senescent cells (c); …Fig. 2A shows the schematic of RBC maturation and its parameterization by the model (p.462, col.1, and fig.2.)
Regarding the claim 3 recitation for determining a rate of change in white blood cell count, a rate of change in platelet count, a rate of blood loss, or a rate of bone marrow cellular output, Golub teaches reticulocytes (top right of panel A) are released from the bone marrow
into the circulation (p.462, fig. 2A.)
Regarding the claims 4 and 16 recitation of determining …information indicative of a degree of morbidity of the subject, including information indicative of presence of an infection, presence of malignancy, presence of anemia, and/or presence of diabetes, Golub shows in utero iron deficiency is associated with persistent delay in RBC clearance in 2-year-old rhesus monkeys (p.463, fig.3); the single-RBC volume and hemoglobin distributions for IS (panel A, fig. 3) and ID (panel B, fig. 3) animals.
Regarding the claims 5 and 17 recitation of parameters include a rate of RBC volume change and/or a variation of RBC volume change, the claims 6 and 18 recitation of parameters include a rate of RBC hemoglobin reduction and/or a variation of RBC hemoglobin reduction, and the claims 7 and 19 recitation of calculating parameters includes calculating a probability density of RBC volume, RBC hemoglobin content, and/or RBC age as a function of time, Golub teaches probability densities (fig.3) and single-RBC volume and hemoglobin distributions for an iron sufficient (IS) (panel A, fig. 3) and an iron deficient (ID) (panel B, fig. 3) animal (p.463, fig. 3.)
Regarding the claims 8 and 20 expression:" -∇·(Pf)+ ∇·(D∇P) + b(v, h) - d(v, h)", Golub teaches a similar model equation, "-∇·(Pf)+ ∇·(D∇P) + b(v, h) - d(v, h)·P", which describes the volume and hemoglobin dynamics of a typical RBC as a function of its current volume and hemoglobin, accounting for fluctuations in those rates over time (p.462, col.1-2.)
While Golub teaches comparing clearance thresholds in observing states of IS and ID, Golub does not explicitly teach the claim 1, 13-15, 25, and 26 step for determining a pathophysiological state based on the parameters.
Golub does not teach RBC age distribution limitations of claim 9 and 21.
Golub does not teach HbA1c measurements and administering/ adjusting treatments for diabetes of claims 10, 11, 22, and 23.
With respect to the claim 1, 13-15, 25, and 26 step for determining a pathophysiological state based on the parameters, Patel teaches iron deficiency anemia is associated with elevated red cell distribution width (RDW) at the time of diagnosis, (p.426, col.2.)
Regarding the claims 9 and 21 recitation of calculating an RBC age distribution for the subject based on the parameters and the first CBC and/or the second CBC, Patel shows delayed RBC clearance and elevated RDW (i.e., parameters calculated from CBC) are associated with increased mean RBC age (p.424, col.1.)
Regarding the claims 10, 11, 22, and 23 recitations for receiving an HbA1c measurement, determining an HbA1c level indicative of diabetes or prediabetes for the subject by adjusting a nominal HbA1c level based on the RBC age distribution; and administering (adjusting in claims 11 and 23) treatment for diabetes or prediabetes to the subject in response to a determination that the HbA1c measurement for the subject exceeds the HbA1c level for the subject, Patel teaches the glycated hemoglobin fraction (hemoglobin A1c or HbA1c) is routinely measured to assess glucose control in diabetic patients; …and further, tested the prediction that elevated RDW is associated with elevated mean RBC age by measuring vc and HbA1c in non-diabetics (p.424, col.1-p.425, col.2), such that it would be obvious to administer or adjust treatment based on the HbA1c level.
Regarding the claims 12 and 24 recitation of administering a dose of iron supplementation to the subject in response to a determination that the change in the RBC clearance rate does not meet a predefined threshold, Golub, at p.463, cols.1-2, teaches finding a significant difference in the RBC clearance threshold (i.e., between ID and IS animals) …comparisons can be made of empirical clearance thresholds between the groups (ID and IS) in terms of volume and hemoglobin content. … (the study) finds that RBCs in ID animals continue to circulate at significantly lower volumes and hemoglobin contents than they do in IS animals, even after normalizing for the lower MCV and MCH in the ID cohort (p.463, cols.1-2.) Additionally, Golub shows iron supplementation (p.460, col.1.)
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the method for modeling RBC population dynamics by calculating and determining parameters using CBC data of Golub with the use of CBC data in determining of pathophysiological states and analysis of HbA1c measurements of Patel, to come to a method using CBC data and/or HbA1c measurements to model RBC dynamics and inform or adjust treatments in pathophysiological states. One would be motivated to combine, as Golub states disease phenotypes, such as risk of diabetes, involve mechanisms that are challenging to elucidate… mathematical modeling can decompose these complex phenotypes (p.465, col.1, while Patel states future studies…will enable model improvements which will likely enhance predictive accuracy (p.427, col.1.) One of ordinary skill would have had a reasonable expectation of success in combining, as Golub and Patel are generally drawn to related teaching of modeling RBC population dynamics, and as such the combination would have been obvious.
