Office Action

§103 §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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 11/19/2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 10 and 13-15 are rejected under 35 U.S.C. 103 as being unpatentable over Mashiach (WO 2014096971 A2) in view of Pepin et al. (US 10,370,594 B2). Regarding claim 10, Mashiach discloses a method of using a wireless communication system (figures 1-5) through a tissue of a patient, the method comprising steps of: providing a first device (110) including a first device data receiver, a first device electrode, and a stimulator; receiving a signal through the first device data receiver, generating an electrical stimulation; coupling the electrical stimulation to the tissue of the patient (through electrodes 158a and 158b) (paragraphs [028], [034], [046] and [050]) Mashiach does not explicitly disclose generating a bi-phasic electrical stimulation pulse; coupling the bi-phasic electrical stimulation pulse to the tissue of the patient. However, Pepin et al. (figure 1) disclose a device (102) including a first device data receiver, receiving a signal through the first device data receiver, generating a bi-phasic electrical stimulation pulse; and coupling the bi-phasic electrical stimulation pulse to the tissue of the patient (through electrode 104 and 106) (column 4, line 24 – column 7, line 3). Therefore, it would have been obvious for one having ordinary skill in the art before the effective filing date of the claimed invention to adapt the teaching of generating a bi-phasic electrical stimulation pulse; coupling the bi-phasic electrical stimulation pulse to the tissue of the patient of Pepin et al. to the method of Mashiach to reduce power consumption and maintain high system reliability. Regarding claim 13, Mashiach and Pepin et al. disclose the method of claim 12 above. In addition, Pepin et al. disclose wherein the signal is a configuration signal (column 6, line 41- column 7 line 3). Therefore, it would have been obvious for one having ordinary skill in the art before the effective filing date of the claimed invention to adapt the teaching of configuration signal of Pepin et al. to the method of Mashiach for varying the stimulus parameters depending on the stimulation application. Regarding claim 14, Mashiach and Pepin et al. disclose the method of claim 13 above. In addition, Pepin et al. disclose wherein the generated bi-phasic electrical stimulation pulse is designated one of a pulse-width and a pulse-frequency from the configuration signal (column 6, line 41- column 7 line 3). Therefore, it would have been obvious for one having ordinary skill in the art before the effective filing date of the claimed invention to adapt the teaching of the generated bi-phasic electrical stimulation pulse is designated one of a pulse-width and a pulse-frequency from the configuration signal of Pepin et al. to the method of Mashiach for varying the stimulus parameters depending on the stimulation application. Regarding claim 15, Mashiach and Pepin et al. disclose the method of claim 10 above. In addition, Pepin et al. disclose wherein the generated bi-phasic electrical stimulation pulse is coupled to the tissue of the patient via a plurality of first device electrodes (104 and 106) to enable bi-phasic electrical stimulation. Therefore, it would have been obvious for one having ordinary skill in the art before the effective filing date of the claimed invention to adapt the teaching of coupling the generated bi-phasic electrical stimulation pulse to the tissue of the patient via a plurality of first device electrodes to enable bi-phasic electrical stimulation of Pepin et al. to the method of Mashiach for providing bi-phasic electrical stimulation to the tissue of the patient. Claim(s) 11 is rejected under 35 U.S.C. 103 as being unpatentable over Mashiach (WO 2014096971 A2) in view of Pepin et al. (US 10,370,594 B2) and further in view of Perryman et al. (US 8,849,412 B2). Regarding claim 11, Mashiach and Pepin et al. disclose the method of claim 10 above. Mashiach and Pepin et al. do not explicitly disclose wherein the first data receiver includes a passive envelope detector to detect data. However, Perryman et al. disclose a data receiver includes a passive envelope detector to detect data (column 41, lines 10-35). Therefore, it would have been obvious for one having ordinary skill in the art before the effective filing date of the claimed invention to adapt the passive envelope detector of Perryman et al. to the first data receiver of Mashiach and Pepin et al. for low power consumption, low cost and simplicity. Claim(s) 12 is rejected under 35 U.S.C. 103 as being unpatentable over Mashiach (WO 2014096971 A2) in view of Pepin et al. (US 10,370,594 B2) and further in view of Marnfeldt et al. (US 10,525,253 B2). Regarding claim 12, Mashiach and Pepin et al. disclose the method of claim 10 above. Mashiach and Pepin et al. do not explicitly disclose wherein the stimulator includes a timer which generates the bi-phasic electrical stimulation pulse. However, Marnfeldt et al. disclose a timer which generates bi-phasic electrical stimulation pulse (column 6, lines 33-53). Therefore, it would have been obvious for one having ordinary skill in the art before the effective filing date of the claimed invention to adapt the timer of Marnfeldt et al. to the method of Mashiach and Pepin et al. for pulse formation to occur periodically with a desire frequency. 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 10 and 12 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 4 of U.S. Patent No. 12,144,997. Although the claims at issue are not identical, they are not patentably distinct from each other because claims 10 and 12 of the pending application are being obvious over claim 4 of U.S. Patent No. 12,144,997. Regarding claim 10 of the pending application, claim 4 of U.S. Patent No. 12,144,997 discloses a wireless communication system which all components that obviously perform all the steps of a method of using a wireless communication system through a tissue of a patient, the method comprising steps of: providing a first device including a first device data receiver, a first device electrode, and a stimulator; receiving a signal through the first device data receiver; generating a bi-phasic electrical stimulation pulse; coupling the bi-phasic electrical stimulation pulse to the tissue of the patient. Regarding claim 12 of the pending application, claim 4 of U.S. Patent No. 12,144,997 discloses wherein the stimulator includes a timer which generates the bi-phasic electrical stimulation pulse.

Claim 9 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 12,144,997 in view of Trimberger (US 10,325,646 B1) and further in view of Perryman et al. (US 8,849,412 B2). Regarding claim 9 of the pending application, claim 1 of U.S. Patent No. 12,144,997 and Trimberger disclose the method of claim 1 above. Claim 1 of U.S. Patent No. 12,144,997 and Trimberger do not disclose wherein the first data receiver includes a passive envelope detector to detect data. However, Perryman et al. disclose a data receiver includes a passive envelope detector to detect data (column 41, lines 10-35). Therefore, it would have been obvious for one having ordinary skill in the art before the effective filing date of the claimed invention to adapt the passive envelope detector of Perryman et al. to the first data receiver of claim 1 of U.S. Patent No. 12,144,997 and Trimberger for low power consumption, low cost and simplicity. Claim 11 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 4 of U.S. Patent No. 12,144,997 in view of Perryman et al. (US 8,849,412 B2). Regarding claim 11 of the pending application, claim 4 of U.S. Patent No. 12,144,997 and Trimberger disclose the method of claim 10 above. Claim 4 of U.S. Patent No. 12,144,997 does not disclose wherein the first data receiver includes a passive envelope detector to detect data. However, Perryman et al. disclose a data receiver includes a passive envelope detector to detect data (column 41, lines 10-35). Therefore, it would have been obvious for one having ordinary skill in the art before the effective filing date of the claimed invention to adapt the passive envelope detector of Perryman et al. to the first data receiver of claim 4 of U.S. Patent No. 12,144,997 for low power consumption, low cost and simplicity. Conclusion The following are suggested formats for either a Certificate of Mailing or Certificate of Transmission under 37 CFR 1.8(a).
