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. 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 1-5 and 8 are rejected under 35 U.S.C. 103 as being unpatentable over Bassi (US 20190038894) in view of Evans (US 20190001127) and further in view of JP674 (JP 6740526) and its translation (EspaceNet Translation of JP 6740526). Regarding claim 1, Bassi discloses an esophageal balloon catheter (Figs. 1 and 3A; esophageal catheter 210 with inflatable member 250; [0059]) comprising: a catheter that carries a nutrient substance to sustain a patient (“the esophageal catheter may include a feeding tube for administration of substances including food stuff and nutrients”; [0068]); an inflatable balloon positioned along a length of the catheter (Fig. 3A; “inflation member 250 runs along a length of the tubular esophageal catheter”; [0059]) , the inflatable balloon having an exterior surface (see Fig. 3A; inflatable member 250 has exterior surface); a set of electrodes on the exterior surface of the inflatable balloon (see Fig. 3A; electrodes 220 are positioned on inflatable member 250; [0059] and [0060]), the set of electrodes including a first electrode and a second electrode (see Fig. 3A; electrodes 220; 4 electrodes 220a-d; [0060]), Bassi does not disclose the set of electrodes capable of stimulating a phrenic nerve of the patient when inserted within an esophagus of the patient; at least one wire capable of providing power to the set of electrodes; and a connector comprising: a balloon port, fluidly coupled to the inflatable balloon, to receive gases for inflating the inflatable balloon: an injection port, fluidly coupled to the catheter, to receive the nutrient substance and a power port electrically coupled to the set of electrodes via the at least one wire.

Applicant’s arguments, see page 8, filed August 20th, 2025, with respect to the rejections of claims 1-8 under 35 USC § 102 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made over Bassi (US 20190038894) in view of Evans (US 20190001127) and further in view of JP674 (JP 6740526) and its translation (EspaceNet Translation of JP 6740526). Applicant's arguments filed August 20th, 2025 have been fully considered but they are not persuasive. On pages 8-9 of the remarks, Applicant argues that Evans does not disclose the amended language of claim 9 where after providing the second nerve stimulation to the patient, receiving a second breathing parameter of the patient; and based on the second breathing parameter reducing delivery of ventilation while maintaining the second nerve stimulation”. However, the examiner disagrees because Evans discloses a system that “may include a first nerve stimulator configured to stimulate a first nerve, wherein stimulation of the first nerve assists or causes contraction of a respiratory muscle in the subject ; and a processor configured to: receive a test result of a vagus nerve activity in the subject, and generate a stimulation parameter based on the test result; and a second nerve stimulator configured to stimulate a second nerve based on the stimulation parameter” [0046]. In other words, Evans discloses a method to stimulate a first nerve (based on parameters), receive a breathing parameter (test result of vagus nerve activity referring to active of breathing muscles), determine second values (stimulation parameter) based on the breathing parameter (test result) and provide a second stimulation based on the breathing parameter (stimulation parameter created from the test result). It would have been readily understood by one of ordinary skill in the art that if the processor is configured to receive test results and create stimulation parameters then a second breathing parameter could be received. Evans further states that stimulation of phrenic nerves may pace the diaphragm muscle so that the pressure and time required from the mechanical ventilation are reduced [0063] and that the external respiratory support 88 (ventilator/ventilation) can be reduced or even eliminated during a portion of or all of the deliver of stimulation set or stimulation session [0138]-[0139] (may maintain second stimulation and reduce ventilation during the stimulation session). Therefore, the examiner maintains the rejection of claim 9 and its dependents. On page 9 of the remarks, Applicant argues the Office Action has not established a prima facie case of obviousness for each of the 103 rejections made (see Non Final Rejection filed May 8th, 2025). However, each of the 103 rejections have established a prima facia case of obviousness where each obvious states starts with It would have been obvious… to modify (art 1) with (art 2) and a reason explaining why. For instance, Evans is modified with an analogous/similar phrenic nerve stimulation system of Bhattacharya where it discloses some of the limitations of claim 17 and then further states that “It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the external respiratory system of Evans with the ability to adjust parameters based on tidal volumes as taught in Bhattacharya to achieve a desired contraction and corresponding tidal volume depending on the patient (Bhattacharya: Paragraph 0056, Lines 1-5).” As such applicant’s argument is unpersuasive. On page 9 of the remarks, Applicant argues that Claims 6-8 ultimately depend from claim 1 and for the reasons above are allowable. This argument is rendered moot in view of new rejections pursuant to claims 1-3, and 5-8. On page 10 of the remarks, Applicant argues that Claims 12, 13, and 16 ultimately depend from claim 9 and thus are allowable for these reasons. However, the examiner disagrees (see reasonings as discussed above). Further claim 13, has been amended to disclose unassisted breathing, please refer to claim 18 where Govari discloses such limitation and reason to modify. On page 10 of the remarks, Applicant argues with respect to claim 17 that the cited references fail to teach at least a ventilator for providing mechanical ventilation and nerve stimulation to a patient, the ventilator comprising a nerve stimulation port”. Applicant further argues that none of the features of the catheter of Fell could possibly disclose a ventilator having a nerve stimulation port. However, the catheter of Fell is not being used to disclose the ventilator but rather modify the catheter/esophageal of Evans in order to provide a nerve stimulation port that directs wires from a power source (providing power) to the electrodes (see Non-Final Rejection filed on May 8th, 2025). The external respiratory support 88 (ventilator) of Evans comprises the catheter/esophageal tube and the computer unit 18 (controls power/stimulation, see [0123]) where power is provided to the nerve stimulation port as modified in the rejection above. Therefore, the ventilator comprises the nerve stimulation port through the catheter/esophageal tube. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
