DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Amendment
In response to amendment filed April 20, 2026, claims 1, 3-6 and 8-11 are amended. Claims 2 and 7 are cancelled and no new claims have been added. Claims 1, 3-6 and 8-11 are pending.
Response to Arguments
Applicant's arguments filed April 20, 2026 with respect to the rejection of claims under 35 U.S.C 101 have been fully considered but they are not persuasive.
In response to applicant’s arguments that the claims do not recite an abstract idea, Examiner respectfully disagrees. The abstract ideas are identified as the steps of “detecting”; “stopping”; “interpolating”; and “calculating”. That is, as broadly and reasonably interpreted, the above recited steps of detecting, stopping, interpolating and calculating are steps that can practically be performed in the mind or with the aid of pen/paper. A physician can perform the claimed step of acquiring by mentally noting sensor data and detect a timing by mentally noting a timing of a swing phase, stopping the acquiring of data mentally and further interpolating by mentally interpolating data into a time period. The experienced physician can then calculate a gait parameter by looking at the sensor data obtained. Thus, the claims can be readily interpreted as being a mere application of a mental process on a computer. Thus, the claims can be readily interpreted as being a mere application of a mental process on a computer. An improved abstract idea is still an abstract idea even if such an abstract idea results in more accurate results. Applicant refers to the tangible claim elements that are in addition to the abstract idea (i.e., the additional elements). Applicant argues that because the additional elements are tangible, the claims are not directed to an abstract idea. However, this is not the test for eligibility. “As the Supreme Court explained in Alice Corp., mere physical or tangible implementation of an exception does not guarantee eligibility.” MPEP 2106.04(d) I. citing Alice Corp. Pty. Ltd. v. CLS Bank Int’l, 573 U.S. 208, 224, 110 USOQ2d 1976, 1983-84 (2014). Thus, applicant’s identification of the additional elements in the claims as not being abstract does not influence the eligibility analysis. Applicant should not conflate the abstract idea with the elements of the claim that are in addition to the abstract idea (i.e. additional elements).
In response to Applicant’s argument that the claims integrate the abstract idea into practical application, Examiner respectfully disagrees. An improvement to the technology cannot be in the abstract idea. MPEP 2106.05a. “[L]imitations that amount to merely indicating a field of use or technological environment in which to apply a judicial exception do not amount to significantly more than the exception itself, and cannot integrate a judicial exception into a practical application.” MPEP 2106.05(h). “[T]he additional element in Flook ... was not sufficient to make the claim eligible, because it was merely an incidental or token addition to the claim that did not alter or affect how the process steps of calculating the alarm limit value were performed.” Further, the data-gathering step of “acquiring” and the data-output steps of “transmitting and displaying” do not add a meaningful limitation to the claims as they are insignificant extra-solution activity. Furthermore, the abstract idea amounts to simply implementing the abstract idea on a computer. For example, the recitations regarding the generic computer components for acquiring, detecting; stopping; interpolating, calculating, transmitting, stopping, performing, inserting, executing, displaying merely invoke a computer as a tool to perform an existing process. The additional elements are identified in the 101 section below as being the elements that comprise a first memory; a first processor; a sensor including acceleration sensor and angular velocity sensor; a data processing device; a second memory; a second processor; a data sampling counter; and a terminal device. When considered in combination, the additional elements (i.e. the generic computer functions and conventional equipment/steps) do not amount to significantly more than the abstract idea. Looking at the claim limitations as a whole adds nothing that is not already present when looking at the elements taken individually. There is no indication that the combination of elements improves the functioning of a computer or improves any other technology. Their collective functions merely provide conventional computer implementation.
Applicant’s arguments, see Remarks, filed April 20, 2026, with respect to the rejection of claims under 35 U.S.C 102 and 35 U.S.C 103 have been fully considered and are persuasive in view of the amendments. The rejection of claims 1-5 and 8-11 under 35 U.S.C 103 and the rejection of claims 6-7 under 35 U.S.C 103 has been withdrawn.
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, 3-6 and 8-11 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more.
Claims 1, 3-6 and 8-11 are all within at least one of the four categories.
The independent claim 1 recites:
acquire sensor data related to a motion of the foot from the sensor;
detect a timing of a swing phase;
stop the data sampling counter to temporarily stop the acquiring of the sensor data;
interpolate interpolation data into a period in which sensor data is lost due to the stop of the acquiring of the sensor data; and
calculate a gait parameter by using the sensor data obtained by interpolating the interpolation data
The independent claim 10 recites:
acquiring sensor data related to a motion of the foot from the sensor;
detecting a timing of a swing phase;
stopping the data sampling counter to temporarily stop the acquiring of the sensor data;
interpolating interpolation data into a period in which sensor data is lost due to the stop of the acquiring of the sensor data; and
calculating a gait parameter by using the sensor data obtained by interpolating the interpolation data
The independent claim 11 recites:
acquiring sensor data related to a motion of the foot from the sensor;
detecting a timing of a swing phase;
stopping the data sampling counter to temporarily stop the acquiring of the sensor data;
interpolating interpolation data into a period in which sensor data is lost due to the stop of the acquiring of the sensor data; and
calculating a gait parameter by using the sensor data obtained by interpolating the interpolation data
The above claim limitations constitute an abstract idea that is part of the Mathematical Concepts and/or Mental Processes group identified in the 2019 Revised Patent Subject Matter Eligibility Guidance published in the Federal Register (84 FR 50) on January 7, 2019. See footnotes 14 and 15.
“A mathematical relationship is a relationship between variables or numbers. A mathematical relationship may be expressed in words ….” October 2019 Update: Subject Matter Eligibility, II. A. i. “[T]here are instances where a formula or equation is written in text format that should also be considered as falling within this grouping.” Id. at II. A. ii. “[A] claim does not have to recite the word “calculating” in order to be considered a mathematical calculation.” Id. at II. A. iii. See for example, SAP Am., Inc. v. InvestPic, LLC, 898 F.3d 1161, 1163-65 (Fed. Cir. 2018) (performing a resampled statistical analysis to generate a resampled distribution).
The claimed steps of acquiring; detecting; stopping interpolating and calculating can be practically performed in the human mind using mental steps or basic critical thinking, which are types of activities that have been found by the courts to represent abstract ideas.
Examples of ineligible claims that recite mental processes include:
a claim to “collecting information, analyzing it, and displaying certain results of the collection and analysis,” where the data analysis steps are recited at a high level of generality such that they could practically be performed in the human mind, Electric Power Group, LLC v. Alstom, S.A.;
claims to “comparing BRCA sequences and determining the existence of alterations,” where the claims cover any way of comparing BRCA sequences such that the comparison steps can practically be performed in the human mind, University of Utah Research Foundation v. Ambry Genetics Corp.
a claim to collecting and comparing known information (claim 1), which are steps that can be practically performed in the human mind, Classen Immunotherapies, Inc. v. Biogen IDEC.
See p. 7-8 of October 2019 Update: Subject Matter Eligibility.
With respect to the pending claims, for example, a physician can perform the claimed step of acquiring by mentally noting sensor data and detect a timing by mentally noting a timing of a swing phase, stopping the acquiring of data mentally and further interpolating by mentally interpolating data into a time period. The experienced physician can then calculate a gait parameter by looking at the sensor data obtained. Thus, the claims can be readily interpreted as being a mere application of a mental process on a computer.
Regarding the dependent claims, the dependent claims are directed to either 1) steps that are also abstract or 2) additional data output that is well-understood, routine and previously known to the industry. For example, dependent claims recite steps (e.g. interpolating and executing) that can be performed in the mind. Although the dependent claims are further limiting, they do not recite significantly more than the abstract idea. A narrow abstract idea is still an abstract idea and an abstract idea with additional well-known equipment/functions is not significantly more than the abstract idea.
This judicial exception (abstract idea) in claims 1, 3-6 and 8-11 is not integrated into a practical application because:
The abstract idea amounts to simply implementing the abstract idea on a computer. For example, the recitations regarding the generic computing components for acquiring, detecting; stopping; interpolating, calculating, transmitting, stopping, performing, inserting, executing, displaying merely invoke a computer as a tool.
The data-gathering step (acquiring) and the data-output step (displaying, transmitting) do not add a meaningful limitation to the method as they are insignificant extra-solution activity.
There is no improvement to a computer or other technology. “The McRO court indicated that it was the incorporation of the particular claimed rules in computer animation that "improved [the] existing technological process", unlike cases such as Alice where a computer was merely used as a tool to perform an existing process.” MPEP 2106.05(a) II. The claims recite a computer that is used as a tool for acquiring, detecting; stopping; interpolating, calculating, transmitting, stopping, performing, inserting, executing, displaying.
The claims do not apply the abstract idea to effect a particular treatment or prophylaxis for a disease or medical condition. Rather, the abstract idea is utilized to determine a relationship among data to provide information about gait.
The claims do not apply the abstract idea to a particular machine. “Integral use of a machine to achieve performance of a method may provide significantly more, in contrast to where the machine is merely an object on which the method operates, which does not provide significantly more.” MPEP 2106.05(b). II. “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 provide significantly more.” MPEP 2106.05(b) III. The pending claims utilize a computer for acquiring, detecting; stopping; interpolating, calculating, transmitting, stopping, performing, inserting, executing, displaying. The claims do not apply the obtained data to a particular machine. Rather, the data is merely output in an post-solution step.
The additional elements are identified as follows: a first memory; a first processor; a sensor including acceleration sensor and angular velocity sensor; a data processing device; a second memory; a second processor; a data sampling counter; and a terminal device.
Those in the relevant field of art would recognize the above-identified additional elements as being well-understood, routine, and conventional means for data-gathering and computing, as demonstrated by
Applicant’s background in the specification;
Applicant' s specification (para [0050]-[0051], [0096], [0110]-[0120]) which discloses that sensors, terminal device, memory, processor data sampling counter and data processing device comprise generic computer components that are configured to perform the generic computer functions (e.g. acquiring, transmitting, displaying) that are well-understood, routine, and conventional activities previously known to the pertinent industry; and
the patent publications cited herewith:
Wilson (US 11158422 B1)
See Fig. 1
the non-patent literature cited herewith:
Jasiewicz, Jan M., et al. "Gait event detection using linear accelerometers or angular velocity transducers in able-bodied and spinal-cord injured individuals." Gait & posture 24.4 (2006): 502-509.
see Fig. 1 and Section 2: Methods
Thus, the claimed additional elements “are so well-known that they do not need to be described in detail in a patent application to satisfy 35 U.S.C. § 112(a).” Berkheimer Memorandum, III. A. 3.
Furthermore, the court decisions discussed in MPEP § 2106.05(d)(lI) note the well-understood, routine and conventional nature of such additional elements as those claimed. See option III. A. 2. in the Berkheimer memorandum.
When considered in combination, the additional elements (i.e. the generic computer functions and conventional equipment/steps) do not amount to significantly more than the abstract idea. Looking at the claim limitations as a whole adds nothing that is not already present when looking at the elements taken individually. There is no indication that the combination of elements improves the functioning of a computer or improves any other technology. Their collective functions merely provide conventional computer implementation.
Examiner Note on Prior Art
The closest prior arts of record Wilson (US 11158422 B1; previously cited); Ahn (US 20160074272 A1; previously cited) do not teach or suggest “detecting a timing of a swing phase for wireless transmitting a gait parameter during a wireless communication period; stopping a data sampling counter to temporarily stop the acquiring of the sensor data during wireless communication period; the data sampling counter is stopped during the swing phase while the gait measurement device is wirelessly transmitting the gait parameter; and the gait parameter wirelessly transmitted while the data sampling counter is stopped during the swing phase” In combination with the required elements of the claim and when considered as a whole.
