Office Action

§DP
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 . Double Patenting 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. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 20 and 22-37 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11,974,855 in view of Sullivan et al. (Sullivan: Pub. No. 2018/0184933). While the ‘855 patent does not include recitation of WCD support structure and a discharge circuit, those of ordinary skill in the art would have recognized application of the present invention to any system designed to detect the ECG, since poor quality signals would negatively affect operation of any device, and any system capable of ensuring signal quality would have been advantageous in the art of medical devices. The WCD is a well-known and widely used system capable of collecting ECG signals and delivering stored electrical charge to the patient based on analysis of the signals as shown by Sullivan. All WCDs have support structures and discharge circuits to respectively hold the electrodes on the body and issue defibrillation/cardioversion therapy. Ambulatory monitors especially may be subject to noise. To therefore include such standard features in the invention of ‘855 would have been considered obvious to those of ordinary skill in the art. Regarding claim 37, the claimed ‘855 invention recites determining heart data for a predetermined time and calculating the percentage deviation or variance range in values from the mean during said time (see claim 6). Response to Arguments Applicant's arguments filed 2/5/26 have been fully considered but they are not persuasive. The submitted amendments are insufficient to overcome the applied obviousness-type double patenting rejection. The inclusion of the processor configured to control, based on the recited analysis of the heart data associated with the at least one channel, delivery of the stored electrical charge to the patient, was considered sufficient to overcome the applied §101 rejection in view of the Vanda Memo. The calculation of heart rate and QRS width associated with each of at least three channels, and comparison to a consistency threshold, allows for more accurate diagnosis by selecting for analysis the most consistent channel, and thus permits more effective treatment application by the wearable cardioverter defibrillator system, thus integrating the abstract idea into a practical application. The closest prior art concerning this feature, Lui, utilizes a correlation coefficient based on an average value of the signals within the various leads to reflect the overall signal quality, but does not discuss calculation of heart rate and QRS width values associated with each channel in order to determine consistency when compared to a consistency threshold. Conclusion THIS ACTION IS MADE FINAL. 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.
