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 . This is a response to the amendment filed 10/27/2025. Claims 1-2, 4-6, 8-14 and 16-26 are pending and are under examination. 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 1-2, 4-6, 8-14, 16-26 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. In claim 1, the recitation of “the second supply terminal” (line 13) is indefinite because it is incorrect. It should be the first supply terminal (i.e. terminal 108 of figure 2). Similarly, the recitation of “the first supply terminal” (line 18) should be the second supply terminal (i.e. terminal 114; figure 2). Since, the metes and bounds of the claim cannot be readily determined renders the claim indefinite. In claim 8, the recitation of “the first voltage terminal” (line 14) is indefinite because it is incorrect. It should be “a second voltage terminal” (i.e., terminal 114; figure 2). Since, the metes and bounds of the claim cannot be readily determined renders the claim indefinite. In claim 9, the recitation of “a second voltage terminal” (line 9) is indefinite because it is incorrect. A second voltage terminal should be a third voltage terminal (i.e., terminal 110; figure 2). Since, the metes and bounds of the claim cannot be readily determined renders the claim indefinite. In claim 10, the recitation of “the second voltage terminal” (line 2) should be the third voltage terminal. Since, the metes and bounds of the claim cannot be readily determined renders the claim indefinite. In claim 14, the recitation of “the first voltage terminal” (lines 20-21) is indefinite because it is incorrect. It should be a second voltage terminal (i.e., terminal 114; figure 2). Since, the metes and bounds of the claim cannot be readily determined renders the claim indefinite. In claim 16, the recitation of “a second voltage terminal” (line 9) should be a third voltage terminal (i.e. terminal 110, figure 2). Since, the metes and bounds of the claim cannot be readily determined renders the claim indefinite. Claim 24 is indefinite because it repeats the limitation of claim 1. Thus, the metes and bounds of the claim cannot be readily determined renders the claim indefinite. In claim 26, the recitation of “a second voltage terminal” (line 4) should be a third voltage terminal (i.e. terminal 110, figure 2). Since, the metes and bounds of the claim cannot be readily determined renders the claim indefinite. Claims 2, 4-6, 11-13, 17-23 and 25 are also indefinite because of the technical deficiencies of claim 1. Allowable Subject Matter Claims 1-2, 4-6, 8-14, 16-26 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. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
