Office Action

§103 §112
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 . Claim Objections Claim 8 is objected to because of the following informalities: In claim 8, “each sector piece” should read “each sensor piece.” Appropriate correction is required. 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. Claim 9 is 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. In Claim 9, the claim limitation “bolt structures” renders the claim indefinite because the limitation is unclear. It is unclear how the bolt structures are defined. Is a bolt structure a securing point? Or is it a bolt? For purposes of examination, the claim limitation is interpreted as an element that secures the sensor piece to the frame. 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. Claims 1-13 are rejected under 35 U.S.C. 103 as being unpatentable over Kato (US 20080262327 A1) in view of Kincaid et al. (US 20200054378 A1).

Regarding Claim 18, Kato in view of Kincaid, Choi, and de Goeij teaches the method of claim 17. Kato in view of Kincaid is silent in teaching comprising correlating sequences of CO2 concentration readings with sleep stages identified with polysomnography; training a dynamic data wrapping (DTW) model based upon the correlated sequences of CO2 concentration readings; and identifying a sleep stage of a subsequent sequence of CO2 concentration readings using the trained DTW model. Choi teaches comprising correlating sequences of CO2 concentration readings (Choi | Paragraph 0059); training a model based upon the correlated sequences of CO2 concentration readings, and using the trained model (Choi | Abstract; [Examiner’s note, the integrated multimodal system continuously monitors, stores, and analyzes multiple dynamic data streams in a manner which effectively trains a model.]). One having an ordinary skill in the art the time the invention was filed would have found it obvious to modify the method from Kato in view of Kincaid to incorporate the teachings of polysomnography and dynamic data wrapping (DTW) in correlation to CO2 concentrations from Choi because the dynamic data wrapping allows for real-time continuously monitors, stores, and analyzes multiple dynamic data streams to correlate the user’s symptoms with relation pulmonary diseases (Choi | Paragraph 0065). Kato in view of Kincaid and Choi are silent in teaching correlating CO2 with sleep stages, and identifying a sleep stage of a subsequent sequence of CO2 concentration readings. de Goeij teaches correlating CO2 with sleep stages (de Goeij | Paragraphs 0068, 0078, and 0267-0268), and identifying a sleep stage of a subsequent sequence of CO2 concentration readings (de Goeij | Paragraphs 0061, 0068, 0078, and 0267-0268). One having an ordinary skill in the art the time the invention was filed would have found it obvious to modify the method from Kato in view of Kincaid and Choi to incorporate the teachings of correlating CO2 concentrations with sleep stages from de Goeij because Correlating the user's carbon dioxide concentration with their sleep stage helps determine sleep quality and provides ways to improve it (de Goeij | Paragraph 0078). Kato in view of Kincaid, Choi, and de Goeij are silent in teaching a correlating sequences of CO2 concentration readings with sleep stages identified with polysomnography. Höskuldsson teaches a correlating sequences of CO2 concentration readings with sleep stages identified with polysomnography (Höskuldsson | Paragraphs 0014-0016; Figures 2-3). One having an ordinary skill in the art the time the invention was filed would have found it obvious to modify the method from Kato in view of Kincaid, Choi, and de Goeij to incorporate the teachings of using a polysomnography to correlate the CO2 concentration with sleep stages because the data from the polysomnography can help diagnose a patient who is suffering from Obstructive Sleep Disordered Breathing (OSDB) (Höskuldsson | Paragraphs 0014-0019). Kato in view of Kincaid, Choi, de Goeij, and Höskuldsson are silent in teaching the model is a dynamic data wrapping (DTW). Fries teaches a dynamic data wrapping (DTW) (Fries | Figure 4; Paragraph 0049). One having an ordinary skill in the art the time the invention was filed would have found it obvious to modify the method from Kato in view of Kincaid, Choi, de Goeij, and Höskuldsson to incorporate the teachings of dynamic data wrapping from Fries because it allows for an algorithm used to measure similarity between two data sequences that vary in speed or time (Fries | Paragraph 0044). Regarding Claim 19, Kato in view of Kincaid, Choi, de Goeij, Höskuldsson, and Fries teaches the method of claim 18. Kato in view of Kincaid, Choi, and Höskuldsson, is silent in teaching wherein training of the DTW model is based upon patterns extracted from the correlated sequences of CO2 concentration readings using a shapelet transformation. de Goeij teaches CO2 concentration readings through a CO2 sensor (de Goeji | CO2 sensor – element 310). One having an ordinary skill in the art the time the invention was filed would have found it obvious to modify the method from Kato in view of Kincaid, Choi, and Höskuldsson to incorporate the teachings of a CO2 concentration readings through a CO2 sensor de Goeij because the sensor monitors and accurately measures the CO2 exhaled from the user (de Goeij | Paragraph 0061). Fries teaches training of the DTW model is based upon patterns extracted from the correlated sequences of data readings using a shapelet transformation (Fries | Figure 4; Paragraph 0049). One having an ordinary skill in the art the time the invention was filed would have found it obvious to modify the method from Kato in view of Kincaid, Choi, de Goeij, and Höskuldsson to incorporate the teachings of dynamic data wrapping from Fries because it allows for an algorithm used to measure similarity between two data sequences that vary in speed or time (Fries | Paragraph 0044).
