Double Patenting
Non-Statutory Obviousness-Type Double Patenting: Rejection Based on Anticipation Analysis
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement.

Claims 1-7 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-4, 7, 14, and 15 (respectfully) of U.S. Patent No. 11,642,043 B2. It is clear that all the elements of the application claims 1-7 are to be found in patent claims 1-4, 7, 14, and 15 (respectfully) (as the application claims 1-7 fully encompasses patent claims 1-4, 7, 14, and 15 (respectfully)).  The difference between the application claims 1-7 and the patent claims 1-4, 7, 14, and 15 (respectfully) lies in the fact that the patent claim includes many more elements and is thus much more specific.  Thus, the invention of claims 1-4, 7, 14, and 15 (respectfully) of the patent is in effect a “species” of the “generic” invention of the application claims 1-7.  It has been held that the generic invention is “anticipated” by the “species”.  See In re Goodman, 29 USPQ2d 2010 (Fed. Cir. 1993).  Since application claims 1-7 is anticipated by claims 1-4, 7, 14, and 15 (respectfully) of the patent, it is not patentably distinct from claims 1-4, 7, 14, and 15 (respectfully) of the patent.

Allowable Subject Matter
Claims 1-20 would be allowable if the 35 USC 101 and Double Patenting Rejections were overcome, since the prior art does not teach each and every limitation within the claim language.  The best prior art Qui (Qui, US 2015/0051449 A1) teaches systems, methods and devices for diagnosing sleep apnea (Abstract); wherein end imaging sensor 104 may be configured for continuous or intermittent video (e.g., 1 frame/second) recording during sleep cycles ([0042]). As such, dynamic images of the anatomic changes of the upper airway can be viewed to assess an obstruction or degree of obstruction compared to a baseline profile collected when the subject is awake (Fig. 1; [0042]); wherein the airflow data undulates with larger amplitudes in response to inhalation and exhalation events during the breathing cycle ([0054-0055]); since the data and images are continuously taken through time, the data and images are thus taken when the patient is inhaling and the time between exhaling and inhaling (Figs. 6A-6D and 7; [0054-0055]); and taking images with imaging sensor 104, which can be camera (Fig. 2A; [0021]). However, Qui does not teach wherein images are taken of a “nasal valve” to determine “nasal valve collapse”, “an endoscope”, or a size difference between the “nasal valve” during inhalation and during a period between exhalation and inhalation. Qui also teaches away from using an endoscope since Qui teaches that endoscopic techniques are known that are aimed at monitoring breathing and snoring during the sleep cycle ([0003]). However, such techniques may still require cumbersome equipment to monitor airflows within the upper airway and further lack a means for detecting a sleep position, especially in a remote environment where a trained professional is not present to observe the sleep cycles ([0003]); and wherein the inventor has recognized disadvantages with the approaches above and herein discloses a wearable hollow nasal tube ([0004]).

NEXT OFFICE ACTION: Reasons for Allowance
The following is an examiner’s statement of reasons for allowance: the amendments filed on 02/03/2025 have overcome the rejections within the previous Office Action. Specifically, claims 1-7 have been amended and overcome the 35 USC 101 rejection; claims 8-14 were canceled and thus there is no 35 USC 101 rejection to be made; and claims 15-20 have been amended to overcome the 35 USC 101 rejection. The filing and Approval of a Terminal Disclaimer, on 02/03/2025, for US PATs 11,642,043 B2, 11,957,448 B2, and 10,987,024 B2 overcomes the Double Patenting Rejections made within the previous Office Action. Since the only rejections made in the previous Office Action were 35 USC 101 rejections and Double Patenting rejections, and this issues have been resolved, the claims are allowable. None of the prior art, either alone or in combination, teaches each and every limitation within the claim language and thus the claims are allowable.
Claims 1-7 and 15-27 are allowed.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee.  Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
