Office Action

§101 §102 §103
DETAILED ACTION Acknowledgements The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claims 1-17 are pending. This action is Non-Final. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Election/Restrictions Applicant’s election without traverse of Invention I and Species B (claims 1-2, 8-10, 17) in the reply filed on 1/8/2026 is acknowledged. Claims 3-7, 11-16 are withdrawn. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “a detection unit configured to”, “a modifying unit configured to”, and “an estimating unit configured to” in claims 1-2, 8. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. In review of the disclosure as filed the following statements of correspondence are made: “a detection unit configured to” corresponds to structures of at least one PPG type contact sensors with or without processing capabilities; RGB camera with CPU with programming or dedicated circuitry, and equivalents “a modifying unit configured to” corresponds to structures of CPU with programming or dedicated circuitry, and equivalents “an estimating unit configured to” corresponds to structures of CPU with programming or dedicated circuitry, and equivalents 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 1-2, 8-10, 17 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception without significantly more. The claim(s) recite(s): modify a length of a measurement period based on a pulse pace of the living organism (mathematical concepts and mental processes (i.e. change t to x if pp>60BPM)) estimate biological information from the pulse wave detected in the measurement period (mathematical concepts and mental processes) These claim limitations fall within the identified groupings of abstract ideas: Mathematical Concepts: mathematical relationships mathematical formulas or equations mathematical calculations Mental Processes concepts performed in the human mind (including an observation, evaluation, judgment, opinion) This judicial exception is not integrated into a practical application because: Under the step 2A, analysis is conducted on the additional features of the claim. Under this analysis, the additional features beyond the judicial exception are: Claim 1 a detection unit configured to detect a pulse wave on a living organism (data gathering, insignificant pre-solution activities) a modifying unit configured to (computer/circuit structures used as a tool) an estimating unit configured to (computer/circuit structures used as a tool) These features in the claim do not integrate the exception into a practical application of the exception as the additional elements in the claim do not apply, rely on, or use the judicial exception in a manner that imposes a meaningful limit on the judicial exception, such that the claim is no more than a drafting effort designed to monopolize the exception. Limitation concepts that are indicative of integration into a practical application: Improvements to the functioning of a computer, or to any other technology or technical field - see MPEP 2106.05(a) Applying or using a judicial exception to effect a particular treatment or prophylaxis for a disease or medical condition – see Vanda Memo Applying the judicial exception with, or by use of, a particular machine - see MPEP 2106.05(b) Effecting a transformation or reduction of a particular article to a different state or thing - see MPEP 2106.05(c) 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, such that the claim as a whole is more than a drafting effort designed to monopolize the exception - see MPEP 2106.05(e) and Vanda Memo Limitation concepts that are not indicative of integration into a practical application: Adding the words “apply it” (or an equivalent) with the judicial exception, or mere instructions to implement an abstract idea on a computer, or merely uses a computer as a tool to perform an abstract idea - see MPEP 2106.05(f) Adding insignificant extra-solution activity to the judicial exception - see MPEP 2106.05(g) Generally linking the use of the judicial exception to a particular technological environment or field of use – see MPEP 2106.05(h) Under Step 2B, the claim limitations are evaluated for an inventive concept. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because, when considered separately and in combination, they do not add significantly more to the exception. Analyzing the additional claim limitations individually, the additional limitation that is not directed to the abstract idea are the same as those identified above in step 2A. Such limitations related to the sensors are recognized by the courts as routine data gathering in order to input data to the mathematical algorithm/mental process, and thus, do not add a meaningful limitation to the method as it would be routinely used by those of ordinary skill in the art in order to apply the mathematical algorithm/mental process. In addition, these sensor structures are known from Fontanel et al. (Fontanel, US 2019/0328316) and Venkatraman et al. (Venkatraman, US 2014/0276119), and in general include generic sensors in generic locations producing the expected signals such as photoplethysmographic (PPG) related data signals. The computer structures cited above are claimed as performing generic computer functions routinely used in computer applications. Generic computer components recited as performing generic computer functions that are well-understood, routine and conventional activities amount to no more than implementing the abstract idea with a computerized system. The additional limitations recited in the dependent claims are directed to further details of the data processing and include intended use of the claimed structures (A more specific abstraction is still an abstraction). Looking at the limitations as an ordered combination adds nothing that is not already present when looking at the elements taken individually. Therefore, analyzing the claims as an ordered combination under the Mayo/Alice analysis the features claimed are directed to patent ineligible limitations. 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: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-2, 8, 10, 17 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Fontanel et al. (Fontanel, US 2019/0328316). Regarding claim 1, Fontanel teaches a biological information estimating device (see at least [0051]) comprising: a detection unit configured to detect a pulse wave on a living organism during a measurement period (see at least [0051] PPG); a modifying unit configured to modify a length of the measurement period based on a pulse pace of the living organism (see at least [0105] processors, [0057] “In particular embodiments, data from on one or more bio-sensors (e.g., ECG, PPG, accelerometer) may be monitored and collected from a user, e.g., to measure that user's heart rate, activity, or other related parameters. In particular embodiment, the sensing period (i.e., sampling period or measurement period) or frequency may be adaptive and adjusted based on a number of factors. In particular embodiments, the sensing period may be adjusted based on the user's heart rate, the data from accelerometer, or a combination of both. As an example and not by way of limitation, the sensing period may be adjusted to a shorter time period corresponding to a higher measurement frequency when a user's heart rate increases and/or the user's activity becomes more intense. As an example and not by way of limitation, the sensing period may be adjusted to a longer time period time corresponding to a lower measurement frequency when the user's has a relatively low heart rate (e.g., when the user's heart rate is within their resting area) or the user's activity is less intense.”); and an estimating unit configured to estimate biological information from the pulse wave detected during the measurement period (see at least [0105] processors, Figures 14-17, [0057]). Regarding claim 2, Fontanel teaches wherein the modifying unit reduces the length of the measurement period in response to an increase in the pulse pace (claimed as intended use, claimed structures capable of such: see at least [0105], [0057]). Regarding claim 8, Fontanel teaches wherein the modifying unit reduces the length of the measurement period in response to an increase in a frequency of the pulse wave as detected after the start of the measurement period (claimed as intended use, claimed structures capable of such: see at least [0105], [0057]). Regarding claim 10, Fontanel teaches wherein the biological information includes a pulse rate (see at least Figures 14-17, [0057]). Regarding claim 17, Fontanel teaches wherein increase in the pulse pace is determined based on an increase in a frequency of the pulse wave as detected after the start of the measurement period (claimed as furthering intended use, claimed structures capable of such: see at least [0105], [0057]). Claim Rejections - 35 USC § 103 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Fontanel et al. (Fontanel, US 2019/0328316) as applied to claim 1 above, and further in view of Venkatraman et al. (Venkatraman, US 2014/0276119). Regarding claim 9, the limitations are met by Fontanel, except the limitation of wherein the biological information includes a blood pressure is not directly taught. Venkatraman teaches a related system for measuring physiological data including stress as well as heart rate and others from sensors including PPG (see at least Figure 4a-b, [0123]-[0128]), and teaches the biological information includes a blood pressure (see at least [0119], [0122]-[0124]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine prior art elements according to known methods to yield predictable results of measuring blood pressure in addition to heart rate and stress in order to increase physiological condition/state understanding of the user such as identifying hypertension conditions during stressful events.
