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 . Claim Objections The claims 1 and 3 are objected to because they include reference characters (A1, A2, B1 and B2) which are not enclosed within parentheses. Reference characters corresponding to elements recited in the detailed description of the drawings and used in conjunction with the recitation of the same element or group of elements in the claims should be enclosed within parentheses so as to avoid confusion with other numbers or characters which may appear in the claims. See MPEP § 608.01(m). 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. Claim 3 is 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 recite the limitation “in a case that the first output end A1 outputs a current” and “in a case that the second output end B1 outputs the current”, render the scope of the claim unclear. It is not apparent what specific condition or event constitutes “a case,” nor is it clear when the claimed method step is to be performed or what triggers it. This renders the scope of the claim indefinite. Claim 4 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being depended on claim 3. Allowable Subject Matter Claims 1-2 are allowed. Claims 3-4 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. Regarding claim 1, Fu et al. (US 2022/0221612) discloses a signal transmission device [fig. 1] shortening turn-off time of controlled source in electromagnetic method, comprising: a first electronic switch [K1/K2/K3/K4]; a twisted pair cable [transmission coil, par. 0014]; wherein the first electronic switch constitutes a bridge arm [abstract]; the first electronic switch comprises a first bridge arm switch [K1], a second bridge arm switch [K2], a third bridge arm switch [K4] and a fourth bridge arm switch [K3]; a first end of the first bridge arm switch [first end K1] and a first end of the third bridge arm switch [first end K4] are connected together and then are connected with a power supply [DC]; a second end of the first bridge arm switch [second end K1] and a first end of the second bridge arm switch [first end K2] are connected together and then are configured as a first output end [B] of the bridge arm to connect with a first end of the first switch; a second end of the third bridge arm switch [second end K4] and a first end of the fourth bridge arm switch [first end K3] are connected together, but is silent with respect to the above structure in combination with a second electronic switch; the second electronic switch is configured to control turn-on and turn-off of the twisted pair cable; the second electronic switch comprises a first switch and a second switch and configured as a second output end of the bridge arm to connect with a second grounding terminal B2 through a wire; a second end of the second bridge arm switch and a second end of the fourth bridge arm switch are connected together and then are grounded; a second end of the first switch is connected with a first grounding terminal A2 through the twisted pair cable and the second switch; and the signal transmission device and ground constitute a signal transmission loop.
