`
`DETAILED ACTION
`
`Status of Application
`
`Receipt of the claims filed 6/27/2022 are acknowledged.
`
`Claims 19, 21-22, and 24-25 are cancelled.
`
`Claims 1-18, 20, and 23 are pending.
`
`The present application, filed on or after March 16, 2013, is being examined
`
`underthe first inventor to file provisions of the AIA.
`
`Claim Rejections — 35 U.S.C. 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 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 effectivefiling 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 1-18, 20, and 23 are rejected under 35 U.S.C. 103 as being
`
`unpatentable over Hatanaka etal. (WO2018092889A1 Machine Translation)
`
`hereinafter Hatanaka in view of Zhu et al. (CN106957266A Machine Translation)
`
`hereinafter Zhu.
`
`

`

`Application/Control Number: 17/789,379
`Art Unit: 1615
`
`Page 3
`
`Regarding claims 1-18, 20, and 23, Hatanaka discloses a tooth surface treatment
`
`material containing silver ion and iodide complex ion and water (claim 1). The iodide ion
`
`is derived from an iodide salt, the silver ion is derived from silver fluoride (claim 3).
`
`Hatanaka discloses a water-soluble fluoride salt. The one-surface type tooth surface
`
`treatment material of the present invention is for preventing caries (pg. 2).
`
`Hatanaka discloses the composition containing complex ions (A)of silver ions and
`
`iodide ions (A) and water (pg. 3).
`
`Hatanaka does notexplicitly disclose wherein the composition comprises a
`
`methacrylate monomer.
`
`However, Zhu disclosesa fluorine-ion-containing dental resin monomer. A dental
`
`resin monomercontaining fluorine ions. The dental resin prepared using the fluorine-
`
`containing monomer can achieve long-term sustained release and repeated charging
`
`and discharging offluorine ions, effectively prevent the occurrence of dental caries, and
`
`has good antibacterial properties (abstract).
`
`Zhu discloses the acrylic resin monomeris selected from bisphenol A-glycidyl
`
`methacrylate [0026]. Zhu discloses the diluent is selected from triethylene glycol
`
`dimethacrylate [0027]. Zhu discloses the dental resin prepared with the monomer as the
`
`fluoride-containing monomercan realize the release of fluoride ions into the oral
`
`environmentonly by ion exchange and realize the storage and repeated charging and
`
`discharging of fluoride ions with the help of exogenous fluoride-containing substances,
`
`thus realizing the function similar to that of a storage battery in a simple and efficient
`
`mannerand achieving a long-lasting anti-caries effect [0033].
`
`

`
`Zhu discloses a dental resin monomercontaining fluorine ions and a bifunctional
`
`dental resin, and directly cures the solution on tooth enamel by ultravioletlight [0031].
`
`It would have been obvious to one of ordinary skill in the art before the effective
`
`filing date of the claimed invention to modify the composition as previously disclosed by
`
`Hatanaka, wherein the composition comprises methacrylate monomer, as previously
`
`disclosed by Zhu, and arrive at the instant invention.
`
`One of ordinary skill in the art would have been motivated to do so because both
`
`Hatanaka and Zhu arein the field of oral fluoride formulations, and Zhu discloses the
`
`dental resin prepared with the monomerasthe fluoride-containing monomercanrealize
`
`the releaseoffluoride ions into the oral environmentonly by ion exchange andrealize
`
`the storage and repeated charging and discharging of fluoride ions with the help of
`
`exogenous fluoride-containing substances, thus realizing the function similar to that of a
`
`storage battery in a simple and efficient manner and achieving a long-lasting anti-caries
`
`effect [0033]. Further, one having ordinarystill in the art would reasonably expect
`
`successin combining prior art elements according to known methodsto yield
`
`predictable results, see MPEP 2141.
