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 . Priority This application, which discloses and claims only subject matter disclosed in prior Application No. 17219522, filed 3/21/2021, appears to claim only subject matter directed to an invention that is independent and distinct from that claimed in the prior application, and names the inventor or at least one joint inventor named in the prior application. Accordingly, this application may constitute a divisional application. Should applicant desire to claim the benefit of the filing date of the prior application, attention is directed to 35 U.S.C. 120, 37 CFR 1.78, and MPEP § 211 et seq. The presentation of a benefit claim may result in an additional fee under 37 CFR 1.17(w)(1) or (2) being required, if the earliest filing date for which benefit is claimed under 35 U.S.C. 120, 121, 365(c), or 386(c) and 1.78(d) in the application is more than six years before the actual filing date of the application. Applicant is reminded that in order for a patent issuing on the instant application to obtain priority under 35 U.S.C. 119(a)-(d) or (f), 365(a) or (b), or 386(a) or (b), based on priority papers filed in a parent or related Application No. 17/219522 (to which the present application claims the benefit under 35 U.S.C. 120, 121, 365(c), or 386(c) or is a reissue application of a patent issued on the related application), a claim for such foreign priority must be timely made in this application. To satisfy the requirement of 37 CFR 1.55 for a certified copy of the foreign application, applicant may simply identify the parent nonprovisional application or patent for which reissue is sought containing the certified copy. Election/Restrictions Applicant’s election without traverse of elect Invention III in the reply filed on 11/10/2025 is acknowledged. Claims 1, 3 – 5 are pending for considerations. 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 – 5 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 3 recites the limitation "the touch detection operation" in line 10. There is insufficient antecedent basis for this limitation in the claim. Claim 3 line 13 recites “when a contact with the human body is detected, selects the transmission electrodes according to the contact region or the contact position of the human body”. Claim language “a contact with the human body is detected” is related to first detection operation from line 3 – 6. Claim language “selects the transmission electrodes” is related to second detection operation from line 7 – 9. This claim limitation is unclear it is related to “first detection operation” or “second detection operation”. Further, claim language is unclear what is the relationship between “a contact with the human body is detected” and “selects the transmission electrodes”. Claim limitation from line 10 – 13 have same issue. Examiner suggests applicant further improve claim clarify. Claims 1, 4, 5 have same issue because of claim dependency. Allowable Subject Matter Claim 3 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Claims 1, 4, 5 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 20200125186 A1 discloses uplink signal in Figs 1, 6. U.S. Patent Publication 20180046272 A1 discloses sensor controller on Fig. 1.
