Office Action

§102 §103
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 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: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 20,22,23,32,33,35,66,69,70,79,82,95,100,116,281,282,283,285 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lifshitz 20170319292. With regard to claims 20,23,33,35,39,52,66,70,79,82,100, Lifshitz discloses a treatment instrument and method of treating a tooth (fig. 24A) comprising: a fluid platform 2427 comprising a chamber 2425 and an access port to provide fluid communication between a treatment region of a tooth and the chamber 2425, the chamber 2425 having a central axis; a pressure wave generator 2401 comprising a first liquid supply port (see annotation above) disposed to direct a liquid-stream (see paragraph 399) of a first material into the chamber along a stream axis non- parallel to the central axis to generate pressure waves (see fig. 42a and 42b) which show pressure waves acting on a treatment region) having sufficient energy to treat the treatment region; and a second supply port (see above annotation) distal the first liquid supply port, the second supply port disposed to direct a second material to be entrained with the liquid stream into the chamber. With further regard to claims 20,66,95, note how the first liquid supply port comprises a nozzle (see annotated figure below; note how the nozzle has a smaller diameter than the portion immediate downstream). With regard to claims 22,69,95, note first supply line 2409 to deliver the first material to the first supply port, and second supply line (see above annotation) to deliver the second material to the second supply port. With regard to claims 32,79,281 note suction port (see above annotation) which is exposed to the chamber 2425 when the device is inserted into a tooth. This occurs by virtue of the fact that the suction port is in communication with the chamber. With regard to claim 116, the device inherently has a filling mode (when the first/second materials are introduced into the tooth, and a cleaning mode (when the first/second materials act on the tooth, as shown in figures 42a/42b). With regard to claims 282,283,285, note that Lifshitz discloses that the second material may be a salt, which is a curable material. See paragraph 36. PNG media_image1.png 487 908 media_image1.png Greyscale 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 1-4,16,38,39,52,86,87,89,284 are rejected under 35 U.S.C. 103 as being unpatentable over Lifshitz 20170319292 in view of Kasten 5145367. With regard to claims 1,2,4,16,38,39,52,86,87,89, Lifshitz discloses a treatment instrument and method of treating a tooth (fig. 24A) comprising: a fluid platform 2427 comprising a chamber 2425 and an access port to provide fluid communication between a treatment region of a tooth and the chamber 2425, the chamber 2425 having a central axis; a pressure wave generator 2401 comprising a first liquid supply port (see annotation below) comprising a nozzle (note how the nozzle has a smaller diameter than the portion immediate downstream) disposed to direct a liquid-stream (see paragraph 399) of a first material into the chamber along a stream axis non- parallel to the central axis to generate pressure waves (see fig. 42a and 42b) which show pressure waves acting on a treatment region) having sufficient energy to treat the treatment region; and a second supply port (see below annotation) distal the first liquid supply port, the second supply port disposed to direct a second material to be entrained with the liquid stream into the chamber. [AltContent: arrow][AltContent: arrow][AltContent: textbox (Second supply port/second supply line)][AltContent: arrow][AltContent: arrow][AltContent: textbox (First fluid supply port comprising a nozzle)] PNG media_image2.png 331 721 media_image2.png Greyscale [AltContent: textbox (Suction port)][AltContent: textbox (Access port)] With further regard to claims 1,38,86,281, Lifshitz does not disclose the suction port being exposed to the chamber in order to draw waste fluid through the chamber. Kasten discloses a similar device in which a suction port 3 is exposed to a chamber 1, in order to drawn waste fluid through the chamber. See fig. 1. It would have been obvious to one skilled in the art to form the device of Lifshitz so that the suction port is exposed to the chamber, if one wished for a larger suction area to remove waste fluid and debris. With regard to claim 3, note first supply line 2409 to deliver the first material to the first supply port, and second supply line (see above annotation) to deliver the second material to the second supply port. With regard to claim 284, note that Lifshitz discloses that the second material may be a salt, which is a curable material. See paragraph 36. Claims 34 and 81 are rejected under 35 U.S.C. 103 as being unpatentable over Lifshitz 20170319292 in view of in view of Khakpour et al 20160095679. With regard to claims 34,81, Lifshitz does not disclose a vent exposed to ambient air, the vent in fluid communication with an outlet line connected to the suction port, the vent positioned alone the outlet line at a location downstream of the suction port. Khakpour et al disclose a similar device (fig. 9A), in which a suction line includes a vent 63 exposed to ambient air, the vent in fluid communication with an outlet line 62 connected to a suction port, the vent positioned along the outlet line 62 at a location downstream of the suction port. It would have been obvious to one skilled in the art to include a vent exposed to ambient air, in fluid communication with the suction outlet line and downstream of the suction port, with the device of Lifshitz, in view of the teaching of Khakpour et al that a vent regulates pressure inside of the device chamber. See paragraph 185 of Khakpour et al. Claims 15,51 are rejected under 35 U.S.C. 103 as being unpatentable over Lifshitz 20170319292 in view of Kasten 5145367, and further in view of Khakpour et al 20160095679. With regard to claims 15,51, Lifshitz/Kasten does not disclose a vent exposed to ambient air, the vent in fluid communication with an outlet line connected to the suction port, the vent positioned alone the outlet line at a location downstream of the suction port. Khakpour et al disclose a similar device (fig. 9A), in which a suction line includes a vent 63 exposed to ambient air, the vent in fluid communication with an outlet line 62 connected to a suction port, the vent positioned along the outlet line 62 at a location downstream of the suction port. It would have been obvious to one skilled in the art to include a vent exposed to ambient air, in fluid communication with the suction outlet line and downstream of the suction port, with the device of Lifshitz/Kasten, in view of the teaching of Khakpour et al that a vent regulates pressure inside of the device chamber. See paragraph 185 of Khakpour et al. Response to Arguments Applicant’s arguments with respect to claims 1,20,38,66,86,95 have been considered but are moot in view of the newly applied grounds of rejection based on a new interpretation of the Lifshitz reference, as well as the newly applied grounds of rejection including the newly cited reference to Kasten. Applicant’s amendments necessitated the new interpretation of Lifshitz, as well as the newly applied rejection based on the additional reference to Kasten. 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.
