Office Action

§102 §103 §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 . Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Some of the features (but not all) are depicted below: “vent hole” “bottle body” “large circle” “liquid compartment” “fitting face” “circle rim” “upper liquid storage” “pump core cavity” “top ring mouth” Therefore, the features specified in the claims, must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Objections Claims 11, 16, and 17 are objected to because of the following informalities: The recitation of “thru-hole,” is a typographical error. Appropriate correction is required. 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 11-20 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. The claims are generally narrative and indefinite, failing to conform with current U.S. practice. They appear to be a literal translation into English from a foreign document and are replete with grammatical and idiomatic errors. Appropriate correction is required. There is insufficient antecedent basis for these claim limitations: Claim 11 recites the limitations: “the bottle body,” “the mouth of the bottle body” “the liquid compartment,” “the head cap,” “the valve stem,” “the pump core assembly.” Claim 12 recites the following limitations: “the pump mouth,” “the upper catch groove,” “the lower catch ring,” “the inner catch ring,” “the pump core cavity” Claim 13 recites the following limitations: “the inner diameter,” “the ring mouth,” “the top ring mouth,” “the outer ring mouth,” Claim 14 recites the following limitations: “cover latch rib,” “bottom cap latch,” Claim 15 recites the following limitation: “cover mouth,” Claim 17 recites the following limitations: “outer diameter of its edge,” “central hole,” “bottom hole mouth,” Claim 20 recites the following limitation: “the body.” In light of the above mentioned deficiencies, the claims are interpreted as best understood for the purpose of advancing prosecution. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.

Claim Rejections - 35 USC § 103 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 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over Ki (US 7367709 B2) in view of Lee (US 20210000240 A1). Regarding claim 19, in addition to the limitations of claim 11, Ki further discloses the vent hole is located on the bottom side of the inner bottle (through hole 6), the bottle body is fastened and attached to the fixed large circle through the mouth of the inner bottle, and the inner bottle, the fixed large circle, the rotating large circle, the inner sleeve large circle, the pump core assembly, and the head cap are connected sequentially (refer to fig. 15, wherein housing 2 is the inner bottle) however, remains silent to wherein the bottle comprises an inner bottle and an outer bottle; the vent hole is located on the bottom side of the inner bottle, the pump core assembly, and the head cap are connected sequentially to form a replacement bottle. Lee teaches wherein the bottle comprises an inner bottle (refill bottle 14) and an outer bottle (bottle body 12); the pump core assembly (discharge device 30, para. 0058), and the head cap (push cap 100) are connected sequentially to form a replacement bottle (refer to fig. 2, fig. 4, and para. 0048). It would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the dispenser to include a refill bottle. In doing so the modified device allows for convenient refilling of the inner bottle while maintaining a sufficient seal (Lee: paras. 0048 and 0061). Regarding claim 20, in addition to the limitations of claim 19 the already modified device further teaches wherein fastening holes are symmetrically located on the mouth of the outer bottle (refer to the annotated figure below); PNG media_image14.png 422 291 media_image14.png Greyscale lead-in grooves (fastening groove 12d ) are provided on the inner diameter side of the outer bottle mouth corresponding to the fastening holes (para. 0038 and fig. 2), respectively; protruded fixing ribs (coupling member 14b) are provided on the lower outer diameter where the inner bottle is fastened to the rotating large circle (para. 0041), respectively; the body is inserted to the lead-in groove of the outer bottle through the fixing ribs, then revolvably secured to the fastening hole of the inner bottle (via screw-coupling, para. 0042), and the inner body engages with the outer bottle (refer to fig. 5). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Delmon et al. (US 10864539 B2) disclosing an inner and outer bottle with pump module and Altus et al. (US 10981689 B2) disclosing a mixing device for assimilating multiple compartments.
