The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claims 1-20 are being examined in this office action.
Claims 1, 4, 8-18, and 20 are currently amended.
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, 5, 7, 9, 11-12, 14, 16 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 the limitation "the drug" in line 5, “the supply and cut-off current” in line 21, and “the forward movement and the backward movement of the piston” in line 22-23. There is insufficient antecedent basis for these limitations in the claim.
Claim 1 recites the limitation “a moving magnetic body that is long” where “long” is a relative term, rendering the claim indefinite.
All remaining claims are rejected as they depend on independent claim 1.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 2 and 4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gu et al. (KR 20190091160 A) in view of Chuang et al. (CN 110167615 A) and Gamliel et al. (EP 3294384 B10.
Regarding claim 2, Gu discloses the needleless (“… skin treatment apparatus …” – Para [0023]) as recited above, wherein
the current supply unit (power supply unit 150, Fig. 2) applies a current to the first coil for a first preset time and then cuts off supply of current ("… when the current is supplied or not supplied to the first coil unit 146a …" - Para [0046]),
Gu does not expressly disclose a mass of the moving magnetic body is 100 g or less, and the first preset time is set to be 180 ms or less.
Chuang teaches that a mass of the moving magnetic body is 100 g or less ("… the total weight of the syringe is less than 50 grams …" - Para [0049])
Therefore, it would have been obvious, before the effective filing date of the claimed invention, to modify the needless syringe of Gu to include that a mass of the moving magnetic body is 100 g or less as taught by Chuang for needleless delivery of injection (Chuang, Para [0124]).
Chuang does not expressly disclose that the first preset time is set to be 180 ms or less.
Gamliel teaches that the first preset time is set to be 180 ms or less ("… the cycle may be about 1 millisecond.' - Para [0039]) ("… a cycle time refers to the period of time from application of a pressure pulse until the repetitive needleless injection device and the impulse generator are ready to apply another pulse." - Para [0039]).
Therefore, it would have been obvious, before the effective filing date of the claimed invention, to modify the needleless syringe of Gu to include that the first preset time is set to be 180 ms or less as taught by Gamliel so the pressurized liquid may exit from the pressure cell (Gamliel, Para [0045]).
Regarding claim 4, Gu discloses a needleless syringe (“… skin treatment apparatus …” – Para [0023]), comprising

Gu does not expressly disclose that the nozzle portion opening/closing valve opens the passage hole with a fluidic pressure applied by the drug from the drug accommodating portion when the piston moves forward, and closes the passage holes when the fluidic pressure is released.
Gamliel teaches that the nozzle portion opening/closing valve (inlet valve stopper 92, Fig. 6D) opens the passage hole (inlet valve aperture 95, Fig. 6D) with a fluidic pressure applied by the drug ("As plunger rod 82 is retracted, flow of liquid from reservoir 32 via inlet conduit 34 into pressure cell 24 may separate inlet valve stopper 92 from inlet valve aperture 95." - Para [0122]) from the drug accommodating portion (pressure cell 24, Fig. 6D) when the piston moves forward ("Plunger rod 82 is being pushed distally toward orifice 27." - Para [0118]), and closes the passage holes when the fluidic pressure is released ("… restoration forces may act to return inlet valve stopper 92 to inlet valve aperture 95.
