Office Action

§102 §103 §112
DETAILED ACTION In application filed on 10/26/2023, Claims 1-13 are pending. The claim set submitted on 10/23/2023 is considered because this is the most recent claim set with some preliminary amendments. Claims 1-12 are considered in the current office 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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 10/21/2024 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Election/Restrictions Applicant’s election without traverse of Group I in the reply filed on 07/02/2026 is acknowledged. Claim 13 is withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected Groups, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 07/02/2026. Group I, claims 1-12 are considered on the merits below. Claim Objections Claims 6 are objected to because of the following informalities: Claim 6 recites “a fifth microflow path” in line 5. It appears that this limitation should be recited as “the fifth microflow path”. Appropriate correction is required. Further, Claim 6 recites “a plurality of vortex forming flow paths” in lines 3-4. It appears that this limitation should be recited as “the plurality of vortex forming flow paths”. Appropriate correction is required. Claim Rejections - 35 USC § 112 Claims 6-7 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 6 recites the limitation "the traveling direction”. There is insufficient antecedent basis for this limitation in the claim. For the purpose of expedited prosecution, the limitation " the traveling direction" is interpreted by the Examiner as " a traveling direction". Moreover, Claim 7 is rejected by virtue of dependency on Claim 6. 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 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 1-7 and 9-12 are rejected under 35 U.S.C. 102 (a) (1) as being anticipated by Han et al. (US20200205545A1, submitted in IDS 10/21/2024). Regarding Claim 1, Han teaches a microfluidic chip (Abstract…an apparatus for manufacturing cosmetic using instantaneous emulsification) comprising: an inlet portion (referred to as the combination of the fluid injection hole [Para 0095; Fig. 5, ref. 402] and fluid injection hole [Para 0095; Fig. 5, ref. 404]) comprising a first fluid inlet (referred to as the fluid injection hole [Para 0095; Fig. 5, ref. 402]) through which a first fluid (See Para 0095…‘an internal phase fluid’) is introduced (See Para 0095… an internal phase fluid is supplied) and a second fluid inlet (referred to as fluid injection hole [Para 0095; Fig. 5, ref. 404]) through which a second fluid (‘an external phase fluid’) is introduced (See Para 0095… an external phase fluid is supplied); a dissolution portion (referred to as any portion/part of the first connecting flow path [Para 0097, Fig. 5, ref. 403]) comprising a first micro flow path (referred to as first connecting flow path [Para 0097, Fig. 5, ref. 403]) in which a first modular raw material (referred to as ‘surfactant’) dissolved by the first fluid (See Para 0091…an internal phase fluid…includes a surfactant.) is pre-loaded (See Fig. 5…the internal phase fluid is inputted from the internal phase fluid injection hole 402, thereby teaching “preloaded”) and a second micro flow path (referred to as second connecting flow path [Para 0097, Fig. 5, ref. 405]) in which a second modular raw material (See Para 0262…acid fluid) dissolved by the second fluid (See Para 0095… an external phase fluid is supplied) is pre-loaded (See Para 0097… a second connecting flow path 405 which connects the first external phase fluid injection hole 404, thereby teaching “preloaded”); a confluence (referred to as confluence part [Para 0095; fig. 5, ref. 410]) comprising a third micro flow path (referred to as third connecting flow path [Para 0101, Fig. 5, ref. 409]) in which the first fluid (See Para 0095…‘an internal phase fluid’), the first modular raw material (‘surfactant’) dissolved by the first fluid (See Para 0091…an internal phase fluid…includes a surfactant.), the second fluid (See Para 0095… an external phase fluid), and the second modular raw material (See Para 0262…acid fluid) dissolved by the second fluid (See Para 0095… an external phase fluid is supplied) converge (See Para 0095…a confluence part 410 where the internal phase fluid supplied from the internal phase fluid injection hole 402 and the external phase fluid supplied from the first external phase fluid injection hole 404 are joined, thereby teaching “converge”); a stir portion (referred to as mixing section [Para 0095; Fig. 5, ref. 420]) comprising a fourth micro flow path (referred to as fourth connecting flow path [Para 0101, Fig. 5, ref. 407]) which forms a mixed fluid (See Para 0095… are joined while emulsion particles are formed, thereby teaching “a mixed fluid”) by mixing the first fluid (See Para 0095…‘an internal phase fluid’), the first modular raw material (referred to as ‘surfactant’ [Para 0091]) dissolved by the first fluid (See Para 0091…an internal phase fluid…includes a surfactant.), the second fluid (See Para 0095… an external phase fluid is supplied), and the second modular raw material (See Para 0262…acid fluid) dissolved by the second fluid (See Para 0095… an external phase fluid is supplied); and a vortexing portion (referred to as a plurality of mixing parts 421, 422, 423, 424, 425 [Para 0095; Fig. 5]) configured to form a cosmetic content (See Para 0108… it is preferable to be subjected to three or more vortex generation sections in order to achieve emulsification to such an extent as to be suitable as cosmetics) comprising particles (See Para 0117… easy generation of emulsion particles in the first mixing part 421) by creating a vortex (See Para 0117…the first mixing part 421 may include a vortex prompting path 4214 for prompting formation of vortices) and cutting off the mixed fluid (See Para 0208…The emulsification part 444 functions to cause internal phase fluid to break neutralized fluid flow, and internal phase fluid to be dispersed into neutralized fluid in a particle state).

Bausch & Lomb Inc., 909 F.2d 1464, 1469, 15 USPQ2d 1525, 1528 (Fed. Cir. 1990) (emphasis in original). A claim containing a "recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus" if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987). Regarding Claim 12, Han teaches that the first micro flow path (referred to as first connecting flow path [Para 0097, Fig. 5, ref. 403]) to a fifth micro flow path (See Para 0099…initial flow path) are formed inside a plane shape plate (See Para 0093…the same plane inside the plate 400; See fig. 5 for the plane shape of the plate 400 ), and the plate (See Para 0093…the same plane inside the plate 400; See fig. 5 for the plane shape of the plate 400 ) is provided with a protrusion portion (See Para 0091; Fig. 5…a portion or part of the embodiment of the mixing part 423 protruding towards flow path 403) which is protruded toward (See Fig. 5… protruded toward) the first micro flow path (referred to as first connecting flow path [Para 0097, Fig. 5, ref. 403]) and the second micro flow path(referred to as second connecting flow path [Para 0097, Fig. 5, ref. 405]). In addition, claim 12 recites the microfluidic chip of Claim 1 and how it functions. Claim 12 is an apparatus claim and MPEP 2114 recites that "[A]pparatus claims cover what a device is, not what a device does." Hewlett-Packard Co. v. Bausch & Lomb Inc., 909 F.2d 1464, 1469, 15 USPQ2d 1525, 1528 (Fed. Cir. 1990) (emphasis in original). A claim containing a "recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus" if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987). 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Han et al. (US20200205545A1, submitted in IDS 10/21/2024). Regarding Claim 8, Han teaches wherein the width of the first micro flow path (referred to as first connecting flow path [Para 0097, Fig. 5, ref. 403]; Examiner submits, under BRI, that the first connecting flow path has a width) in which the first modular raw material (referred to as ‘surfactant’ [Para 0091]) is disposed, or the width of the second micro flow path where the second modular raw material is disposed (The limitation is optional ) ; the width of the fifth micro flow path (See Para 0099…initial flow path; Examiner submits, under BRI, that the initial flow path has a width). Han does not explicitly teach that “wherein the width of the first micro flow path in which the first modular raw material is disposed, or the width of the second micro flow path where the second modular raw material is disposed are to be formed bigger than the width of the fifth micro flow path” However, Han does teach that the microfluidic chip of Claim 1 is a microfluidic device where the only difference between the prior art and the claim is the bigger width of the first micro flow path in which the first modular raw material is disposed, or the bigger width of the second micro flow path where the second modular raw material is disposed The Federal Circuit held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device (See MPEP § 2144.05, Part II, Subpart B; In Gardnerv.TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984)). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to design and fabricate a microfluidic device wherein the width of the first micro flow path in which the first modular raw material is disposed, or the width of the second micro flow path where the second modular raw material is disposed are to be formed bigger than the width of the fifth micro flow path” for the benefit enabling a user to directly manufacture cosmetic having components exhibiting desirable effects, feeling of use, content ratio (Han, Para 0012), allowing for the providing a product where stability of product should be maintained for a long time from manufacture of cosmetic to the time of use (Han, Para 0011). In addition, claim 8 recites the microfluidic chip of Claim 1 and how it functions. Claim 8 is an apparatus claim and MPEP 2114 recites that "[A]pparatus claims cover what a device is, not what a device does." Hewlett-Packard Co. v. Bausch & Lomb Inc., 909 F.2d 1464, 1469, 15 USPQ2d 1525, 1528 (Fed. Cir. 1990) (emphasis in original). A claim containing a "recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus" if the prior art apparatus teaches all the structural limitations of the claim.
