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. Claims 9-12 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Krasnow (US 10413676 B1) in view of Cioanta et al (US 20180221688 A1). Regarding claim 9, Krasnow discloses the limitations of claim 1 but fails to teach said apparatus further comprising a reflector coupled to the syringe adjacent the shock wave generator. Krasnow teaches that a porous membrane may be designed to allow medication to pass through while providing a surface with good reflective properties for the ultrasonic signals to reflect back towards ultrasonic transducer (col 5, lines 28-32). However, However, Cioanta et al disclose an apparatus that use acoustic pressure shock waves (see para 0002, see fig 1A) comprising a shock wave generator (11) and a reflector (12) coupled to the shock wave generator (see fig 1A). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the pressure wave generator of Krasnow and incorporate the teachings of Cioanta et al to have a reflector coupled to the syringe adjacent the shock wave generator. The modification would provide the benefit of precisely controlling the direction of the signal and increasing signal strength producing focused acoustic pressure shock waves (see para 0120-22). Regarding claim 10, Krasnow in view of Cioanta et al disclose the apparatus of claim 9, Cioanta et al further disclose the reflector is selected from the group consisting of a semi-ellipsoidal reflector, parabolic reflector, and combination semi-spherical and conical reflector (para 0119). Regarding claim 11, Krasnow in view of Cioanta et al disclose the apparatus of claim 10, Krasnow further discloses said apparatus comprising a syringe needle (16) coupled to the syringe funnel (fig 1). Regarding claim 12, Krasnow in view of Cioanta et al disclose the apparatus of claim 9, Krasnow further discloses said apparatus comprising a syringe needle (16) coupled to the syringe funnel (fig 1). Regarding claim 19, Krasnow in view of Cioanta et al discloses the apparatus of claim 12, Krasnow further discloses wherein the chamber includes a liquid treatment substance (20) comprising one or more of a vaccine, drug, antibiotic, medication, mixture of multipleactive ingredients, gene medicine, stem cells, genetic material, RNA or mRNA genetic material, genetic modified material, immune cells cocktail, neutrophils, eosinophils, basophils, mast cells, monocytes, macrophages, dendritic cells, natural killer cells, lymphocyte B cells or T cells, base editor, liposomes, lipid nano-particles, lipid micro-particles, artificially or naturally enveloped active substance, nano-robot, nano-particle, protein, antibody and stem cell, and combinations thereof (fig 3, medication 20). Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Krasnow (US 10413676 B1) in view of Giustetto et al (US 20210069332 A1). Regarding claim 17, Krasnow discloses the limitations of claim 1 and further discloses said apparatus further comprising a control console (50) operably coupled to the pressure wave generator (fig 5) but fails to teach wherein the control console automatically provides control parameters to the generator based on the type of liquid treatment substance provided in the chamber. However, Giustetto et al disclose a system for inducing sonoporation of a drug (abstract) comprising a pressure wave generator (para 0027) and a control unit (input device and processor, para 0029 and 0030) to control parameters to the generator based on the type of treatment substance provided (para 0030-34, data entered include the type of drug). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the apparatus of Krasnow and incorporate the teachings of Giustetto et al to have said apparatus wherein the control console provides control parameters to the generator based on the type of liquid treatment substance provided in the chamber. This modification would provide the benefit of adjusting the timing and intensity of shockwaves based on the specific type of drugs administered (see para 0042). Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over Krasnow (US 10413676 B1) in view of Giustetto et al (US 20210069332 A1) and further in view of Roof (US 20080109260 A1). Regarding claim 18, Krasnow in view of Giustetto et al discloses the limitations of claims 1 and 17, but fails to teach the control console is configured to receive a scanned code identifying the type of liquid treatment substance provided in the chamber. However, Roof discloses a method and a system for capturing drug administration data (abstract and para 003) comprising a medical processing system that includes a handheld scanner configured to receive a scanned code identifying the type of treatment substance (para 0008 and 0009). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the control console of Krasnow and incorporate the teachings of Roof to have said control console configured to receive a scanned code identifying the type of liquid treatment substance provided in the chamber. This modification would provide the benefit of programming the treatment parameters automatically without the need of the user input (see para 0006-0007). Response to Arguments Applicant’s arguments with respect to claim(s) 1-29 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. 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).
