Office Action

§101 §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 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 12-20 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. Claim 12 and 15 (rest by dependency) recite “chord compliance”. It is unclear if Applicant is referring to the first chord-compliance, the second chord-compliance or both. Further, Examiner notes that the claims use the convention “chord-compliance”. 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. Claim 12-17 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. The claim(s) recite(s) determining a change in end expiratory lung impedance in the at least one region of the lung, between the first end expiratory lunge impedance measurements and the second end expiratory lung impedance measurements obtained in the first positive end expiratory pressure and the second positive end expiratory pressure; determining a first chord-compliance of the at least one region of the lung from impedance measurements obtained during the application of the first positive end expiratory pressure; determining a second chord-compliance of the at least one lung of the patient from pixels of a second electrical impedance tomography image of the patient at the second positive end expiratory pressure; and determining a second chord-compliance of the at least one region of the lung from impedance measurements obtained during the application of the second positive end expiratory pressure; determining a threshold value based on one or more values including at least one of oxygenation, thorax response, and chord compliance in response to the first positive end expiratory pressure and the second positive end expiratory pressure; determining a potential lung recruitment value based on the first index and the second index; comparing the potential lung recruitment value to the threshold value; and if the potential lung recruitment value of the patient is within the threshold value, classifying the patient as a responder. The abstract idea is part of the Mathematical Concepts group(s) identified in the 2019 Revised Patent Subject Matter Eligibility Guidance published in the Federal Register (84 FR 50) on January 7, 2019. This judicial exception is not integrated into a practical application because they amount to simply implementing the abstract idea on a computer; data-gathering steps 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; does not apply the abstract idea to effect a particular treatment or prophylaxis for a disease or medical condition; does not apply the abstract idea with, or by use of, a particular machine. The additional elements are identified as follows: electrical tomography device. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the additional elements, when considered both individually and as a whole, do not amount to significantly more than the abstract idea. The additional computer and data-gathering elements, which are recited at a high level of generality, provide conventional computer and data-gathering functions that do not add meaningful limitations to practicing the abstract idea. 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 non-patent literature of record in the application as well as Applicant’s own Specification. 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. When considered in combination, the additional elements (generic computer functions and conventional equipment/steps) do not amount to significantly more than the abstract idea. The Federal Circuit has held that combining additional elements for data-gathering with abstract ideas does not make a claim patent-eligible. 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. Regarding the dependent claims, the dependent claims are directed to either 1) steps that are also abstract or 2) additional data gathering that is well-understood, routine and previously known to the industry. 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 data-gathering equipment/functions is not significantly more than the abstract idea.
