Office Action

§101 §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 . Response to Arguments The amendment filed 11/20/2025 has been entered. Claims 1-20 remain pending in the application. Applicant’s amendments to the claims 1-9, 11-18 and 20 have overcome the statutory double patent rejection; however, there is now a nonstatutory double patenting rejection present which can overcome with a TD, and claims 1-20 have overcome the 112b rejection set forth in the Non-final Office Action mailed 08/27/2025. 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 3-4, 6, 11, 13 and 20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 3-4, 6, 11, 13 and 20 of U.S. Patent No. 11432770 in view of further reasoning. Application 18/220,216 Patent Number 11432770 Claim 3. The method of Claim 1, further comprising, following recording differences between the first set of sense signals and the virtual reference signal: reading a third set of sense signals from the first subset of sense electrodes; detecting abnormal contact between a user's skin and a first sense electrode in the first subset of sense electrodes in response to a third sense signal in the third set of sense signals excluding a first signal component oscillating at the reference frequency; and in response to detecting abnormal contact between the user's skin and the first sense electrode: adjusting the direct-current component of the drive signal according to linear combination of the third subset of sense signals less the third sense signal; and generating an electronic notification to adjust the first sense electrode. Claim 3. The method of claim 1, further comprising, over a second duration of the test period succeeding the first duration: reading a third set of sense signals from the first subset of sense electrodes; detecting abnormal contact between the user's skin and a first sense electrode in the first subset of sense electrodes in response to a third sense signal in the third set of sense signals excluding a first signal component oscillating at the reference frequency; and in response to detecting abnormal contact between the user's skin and the first sense electrode: adjusting the direct-current component of the drive signal according to a second linear combination of the third subset of sense signals less the third sense signal; and generating an electronic notification comprising a prompt to adjust the first sense electrode. Claim 3 does not explicitly disclose: following recording differences between the first set of sense signals and the virtual reference signal. However, claim 3 is dependent on claim 1. Claim 1 states: ‘and recording differences between the first set of sense signals and the virtual reference signal.’ It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to conduct the method as disclosed in claim 3 after determining differences in the signals as disclosed in claim 1. Claim 4. The method of Claim 1, further comprising, following recording differences between the first set of sense signals and the virtual reference signal: reading a third set of sense signals from the second subset of sense electrodes; detecting abnormal contact between a user's skin and a second sense electrode in the second subset of sense electrodes in response to a sense signal in the second set of sense signals excluding a first signal component oscillating at the reference frequency; and in response to detecting abnormal contact between the user's skin and the second sense electrode: deactivating the second sense electrode; and calculating a second virtual reference signal as a function of the second set of sense signals less the sense signal; and recording differences between the first set of sense signals and the second virtual reference signal.

Claim 4 does not explicitly disclose: following recording differences between the first set of sense signals and the virtual reference signal. However, claim 3 is dependent on claim 1. Claim 1 states: ‘and recording differences between the first set of sense signals and the virtual reference signal.’ It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to conduct the method as disclosed in claim 4 after determining differences in the signals as disclosed in claim 1. Further claim 4 does not explicitly disclose: reading a third set. However, it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the method as disclosed with a different subset of electrodes the motivation being obvious to try choosing from a finite number of electrodes sets with a reasonable expectation of success. Claim 6. A method comprising: selecting a first subset of sense electrodes, in a set of sense electrodes integrated into an electroencephalography headset, corresponding to a set of channels; selecting a second subset of sense electrodes, in the set of sense electrodes, differing from the first subset of sense electrodes; during a test period: outputting a drive signal through a driven electrode integrated into the electroencephalography headset worn by a user, the drive signal comprising an alternating-current component oscillating at a reference frequency and a direct-current component; reading a first set of sense signals from the first subset of sense electrodes; reading a second set of sense signals from the second subset of sense electrodes; in response to a second sense signal read from a second sense electrode in the second subset of sense electrodes excluding a first signal component oscillating at the reference frequency detecting abnormal contact between the user's skin and the second sense electrode; and, deactivating the second sense electrode. Claim 6. A method comprising: receiving selection of a set of channels of interest; selecting a first subset of sense electrodes, in a set of sense electrodes integrated into an electroencephalography headset, corresponding to the set of channels of interest; selecting a second subset of sense electrodes, in the set of sense electrodes, differing from the first subset of sense electrodes; during a test period beginning at a first time: outputting a drive signal through a driven electrode integrated into the electroencephalography headset worn by a user, the drive signal comprising an alternating-current component oscillating at a reference frequency and a direct-current component; reading a first set of sense signals from the first subset of sense electrodes; reading a second set of sense signals from the second subset of sense electrodes; in response to a second sense signal read from a second sense electrode in the second subset of sense electrodes excluding a first signal component oscillating at the reference frequency at a second time succeeding the first time, detecting abnormal contact between the user's skin and the second sense electrode; and in response to detecting abnormal contact between the user's skin and the second sense electrode, deactivating the second sense electrode. Claim 6 does not explicitly disclose: reading a second set. However, it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the method as disclosed with a different subset of electrodes the motivation being obvious to try choosing from a finite number of electrodes sets with a reasonable expectation of success. Claim 11. The method of Claim 6, further comprising, at a second time succeeding deactivation of the second sense electrode by a check duration: reactivating the second sense electrode; reading a third sense signal from the second sense electrode; in response to the third sense signal comprising the first signal component oscillating at the reference frequency, detecting proper contact between the user's skin and the second sense electrode at the second time; and in response to detecting proper contact between the user's skin and the second sense electrode, maintaining the second sense electrode in an active state following the second time. 11. The method of claim 6, further comprising, at a third time succeeding the second time by a check duration: reactivating the second sense electrode; reading a third sense signal from the second sense electrode; in response to the third sense signal comprising the first signal component oscillating at the reference frequency, detecting proper contact between the user's skin and the second sense electrode at the third time; and in response to detecting proper contact between the user's skin and the second sense electrode, maintaining the second sense electrode in an active state following the third time. Claim 11 does not explicitly disclose: at a second time. However, It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art use the method with a second time the motivation being obvious to try choosing from a finite amount of times with a reasonable expectation of success. Claim 20. The method of Claim 17, further comprising: reading a reference signal from a second sense electrode in the first subset of sense electrodes; over the first duration within the test period, recording differences between the first set of sense signals and the reference signal to a digital electroencephalography test result file; and over the second duration within the test period, recording differences between the second set of sense signals, less the second sense signal, and the reference signal to the digital electroencephalography test result file. Claim 20. The method of claim 17, further comprising: reading a reference signal from a second sense electrode in the set of sense electrodes; over the first duration within the test period, recording differences between the first set of sense signals and the reference signal to a digital electroencephalography test result file; and over the second duration within the test period, recording differences between the second set of sense signals, less the second sense signal, and the reference signal to the digital electroencephalography test result file. Claim 6 does not explicitly disclose: in the first subset. However, it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the method as disclosed with a different subset of electrodes the motivation being obvious to try choosing from a finite number of electrodes sets with a reasonable expectation of success. A rejection based on double patenting of the “same invention” type finds its support in the language of 35 U.S.C. 101 which states that “whoever invents or discovers any new and useful process... may obtain a patent therefor...” (Emphasis added). Thus, the term “same invention,” in this context, means an invention drawn to identical subject matter. See Miller v. Eagle Mfg. Co., 151 U.S. 186 (1894); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Ockert, 245 F.2d 467, 114 USPQ 330 (CCPA 1957). A statutory type (35 U.S.C. 101) double patenting rejection can be overcome by canceling or amending the claims that are directed to the same invention so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101. Claims 10 and 19 is/are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 10 and 19 of prior U.S. Patent No. 11432770. This is a statutory double patenting rejection. Application 18/220,216 Patent Number 11432770 Claim 10. The method of Claim 9, wherein generating the electronic notification comprises generating the electronic notification comprising a prompt to adjust the first sense electrode and the second sense electrode. 10. The method of claim 9, wherein generating the electronic notification comprises generating the electronic notification comprising the prompt to adjust the first sense electrode and the second sense electrode. Claim 19. The method of Claim 17: wherein selecting the first subset of sense electrodes comprises activating each sense electrode in the first subset of sense electrodes; and further comprising, in response to detecting abnormal contact between the user's skin and the first sense electrode, deactivating the first sense electrode. Claim 19. The method of claim 17: wherein selecting the first subset of sense electrodes comprises activating each sense electrode in the first subset of sense electrodes; and further comprising, in response to detecting abnormal contact between the user's skin and the first sense electrode, deactivating the first sense electrode.
