Office Action

§112
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 . Amendment Entered In response to the amendment filed on August 10th, 2026, amended claims 1-3, 10-12, 22-25, 27-32 and new claims 34-36 are entered. Claims 9, 21, and 26 are canceled. Claims 1-3, 10-12, 22-25, and 27-36 are currently pending and under examination. Response to Arguments Applicant's remarks and amendments with respect to the claim interpretations have been fully considered. The interpretations are withdrawn in view of the amendment. Applicant's remarks and amendments with respect to the rejections under 35 U.S.C. 112(b) have been fully considered. The rejections are withdrawn in view of the amendment. Applicant's remarks and amendments with respect to the rejections under 35 U.S.C. 103 have been fully considered. The rejections are withdrawn in view of the amendment. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-3, 10-12, 22-25, and 27-36 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites “an operational amplifier operatively coupled to the one or more reference electrodes” in lines 15-16. It is unclear as to whether a singular operational amplifier is coupled to the one or more reference electrodes, or if each reference electrode is coupled to a corresponding operational amplifier. Claim 1 recites “wherein the common mode reference output is provided to the second input of the amplifier of the plurality of amplifiers” in lines 17-18. It is unclear as to whether the term “provided to” is meant to be different than “coupled to”, which was previously used in line 9 of Claim 1. Claim 1 recites “wherein the common mode reference output is provided to the second input of the amplifier of the plurality of amplifiers via an output of the operational amplifier” in lines 17-19. It is unclear as to whether a singular common mode reference output is provided to the second input of each amplifier of the plurality of amplifiers, or if each second input of each amplifier of the plurality of amplifiers is provided with its own corresponding common mode reference output. Furthermore, it is unclear as to whether a singular output of the operational amplifier is provided to the second input of each amplifier of the plurality of amplifiers, or if each second input of each amplifier of the plurality of amplifiers is provided with its own corresponding output of the operational amplifier. Claim 24 recites “the common mode reference output being provided to a plurality of amplifiers of the wearable device via an output of the operational amplifier” in lines 11-13. It is unclear as to whether a singular common mode reference output is being provided to each amplifier of the plurality of amplifiers, or if each amplifier of the plurality of amplifiers is provided with its own corresponding common mode reference output. Furthermore, it is unclear as to whether a singular output of the operational amplifier is provided to each amplifier of the plurality of amplifiers, or if each amplifier of the plurality of amplifiers is provided with its own corresponding output of the operational amplifier. Claim 29 recites “the common mode reference output being provided to a plurality of amplifiers of the wearable device via an output of the operational amplifier” in lines 12-14. It is unclear as to whether a singular common mode reference output is being provided to each amplifier of the plurality of amplifiers, or if each amplifier of the plurality of amplifiers is provided with its own corresponding common mode reference output. Furthermore, it is unclear as to whether a singular output of the operational amplifier is provided to each amplifier of the plurality of amplifiers, or if each amplifier of the plurality of amplifiers is provided with its own corresponding output of the operational amplifier.
