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 .
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1-11 are rejected under 35 U.S.C. 103 as being unpatentable over Kanada (US PG Pub 2015/064476; hereafter ‘476).
Claim 1: ‘076 is directed towards a method a multilayer coating film (title), the method comprising:
(1) applying a first water-based paint (P1) onto an object to be coated to form a first film having a cured film thickness (TP1) of 5-70 µm (¶s 21, 322);
(2) applying a second water-based colored paint (P2) onto the first coating film formed in (1) to form a second colored coating film having a cured film thickness (TP2) of 5-70 µm, the second water-based color paint (P2) comprising a binder component (AP2) and an effect pigment (BP2) and having a paint solid content concentration (NVP2) of 25% (¶s 21, 281, 318, 322, 336-346, 391-392);
(3) applying a clear coat paint (P3) onto the second colored coating film formed in (2) to form a clear coating film (¶ 21); and
(4) heating the multilayer coating film including the first coating film formed in (1), the second coating film formed in (2), and the clear coating film formed in (3), and thereby simultaneously curing the multilayer coating film (¶ 21),
the first water-based paint (P1) comprising
a hydroxyl group-containing acrylic resin (A) (¶ 21),
a crosslinking agent (B) (¶ 21), and
acrylic-urethane composite particles (C) containing an acrylic resin component having an acid value of 0-20 mg KOH/g (¶s 21, 235).
Although the taught range of TP1 of 5-70 µm is not explicitly the claimed range of 5-20 µm, it does overlap the claimed range. Therefore it would have been obvious to one of ordinary skill in the art at the time of filing to have incorporated a value within the claimed range since in the case where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976).
Although the taught range of TP2 of 5-70 µm is not explicitly the claimed range of 0.5-7 µm, it does overlap the claimed range. Therefore it would have been obvious to one of ordinary skill in the art at the time of filing to have incorporated a value within the claimed range since in the case where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976).
The taught value of NVP2 of 25% is not the claimed range of 1-18 mass%.
It would have been obvious to one of ordinary skill in the art at the time of filing to optimize the solids concentration of the second water-based colored paint because concentration is prima facie obvious to optimize. Generally, differences in concentration or temperature will not support the patentability of subject matter encompassed by the prior art unless there is evidence indicating such concentration or temperature is critical. "[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). MPEP 2144.05(II)(A).
Claim 2: The substrate is a steel sheet on which a cured electrodeposited coating film is formed, on which an intermediate coating paint is applied to form an intermediate coating film (¶ 321).
Claim 3: ‘476 teaches that the substrate can be coated with an intermediate coating paint prior to applying the multilayer coating film as discussed above (¶ 321).
‘476 also discloses that the prior art teaches that the intermediate coating film in the art can be an aqueous paint (¶ 6).
It would have been obvious to one of ordinary skill in the art at the time of filing to use a water-based paint for forming the intermediate coating because aqueous intermediate paints are art recognized as suitable for forming the intermediate coatings in the field and would have predictably been suitable for the process of ‘476.
Claim 4: The cured film thickness of the intermediate coating film is not taught by ‘476.
However, the thickness of a coating is are result effective variable based on the desired hiding power of a coating as well as other desired properties.
It would have been obvious to one of ordinary skill in the art at the time of filing to optimize the thickness of the coatings to obtain the desired results because thickness of a coating is a result effective variable and it is prima facie obvious to optimize result effective variables.
Claim 5: The hydroxyl group-containing acrylic resin (A) contains a water-dispersible hydroxyl group-containing acrylic resin (A1’) having an acid value of 5-60 mg KOH/g (¶s 61-88).
Although the taught range of 5-60 is not explicitly the claimed range of less than or equal to 20, it does overlap the claimed range. Therefore it would have been obvious to one of ordinary skill in the art at the time of filing to have incorporated a value within the claimed range since in the case where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976).
Claim 6: The acrylic resin (A1’) can comprise a core-shell structure (¶ 269) having an acid value of 5-60 mg KOH/g (¶s 61-88).
Although the taught range of 5-60 is not explicitly the claimed range of less than or equal to 20, it does overlap the claimed range. Therefore it would have been obvious to one of ordinary skill in the art at the time of filing to have incorporated a value within the claimed range since in the case where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976).
Claim 7: ‘476 discloses a polyisocyanate compound component contained in a urethane resin component of the acrylic-urethane composite resin particles (C) comprises, as at least one type of the polyisocyanate compound component, an aliphatic polyisocyanate compound (c1-1) (¶ 195).
Claim 8: ‘476 discloses that the monomer component contained in the acrylic resin component in the acrylic-urethane composite resin particles (C) comprises, as at least one type of the monomer component, a polymerizable unsaturated monomer (c2-1) having one polymerizable unsaturated group per molecule and an alkyl group having from (¶ 209-210).
Claim 9: The monomer component contained in the acrylic resin component of the acrylic-urethane composite resin particles (C) comprises, as at least one type of the monomer component, a polymerizable unsaturated monomer (c2-2) having two or more polymerizable unsaturated groups per molecule (¶ 208).
Claim 10: The content portion of the binder component (AP2) and the effect pigment (BP2) in the second water-based colored paint (P2) is such that a content of the effect pigment (BP2) is in a range of 1-200 parts by mass of 100 parts by mass of total solid content (¶ 282).
Although the taught range of 1-200 parts by mass of 100 parts is not explicitly the claimed range, it does overlap the claimed range. Therefore it would have been obvious to one of ordinary skill in the art at the time of filing to have incorporated a value within the claimed range since in the case where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976).
Additionally, it would have been obvious to one of ordinary skill in the art at the time of filing to optimize the concentration of the pigment because the concentration of pigment is a result effective variable based on the desired hiding power of the coating and concentrations are also prima facie obvious to optimize.
Generally, differences in concentration or temperature will not support the patentability of subject matter encompassed by the prior art unless there is evidence indicating such concentration or temperature is critical. "[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). MPEP 2144.05(II)(A).
Claim 11: The content portion of the effect pigment (BP2) in the second water-based colored paint (P2) is in a range of in a range of 1-200 parts by mass of 100 parts by mass of total solid content (¶ 282).
Although the taught range of 1-200 parts by mass of 100 parts is not explicitly the claimed range, it does overlap the claimed range. Therefore it would have been obvious to one of ordinary skill in the art at the time of filing to have incorporated a value within the claimed range since in the case where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976).

Response to Arguments
Applicant's arguments filed 1/14/26 have been fully considered but they are not persuasive.
In regards to applicant’s argument that the amendment changing the range of NVP2 to 1-18 mass% overcomes the obviousness rejection of claim 1 because an NVP2 value less than 18 mass%, together with other elements of claim 1, resulted in acceptable evaluation with regard to water swelling percentage, dripping resistance, image clarity, and brightness, whereas when the NVP2 value exceeded the claimed maximum value, the evaluation of brightness resulted in failure as shown in Comparative Example 7; the Office does not find this argument convincing because:
Examples 33 (hereafter E33) results in a dripping resistance of A, an image clarity of A, a flip-flop property of C, and a graininess of C;
Comparative Example 7 (hereafter CE7) results in a dripping resistance of A, an image clarity of A, a flip-flop property of D, and a graininess of C;
the disclosure provides that flip-flop property value of A represents a range of greater than or equal to 3.75, B represents a range of 3.25≤B<3.75, C represents a range of 2.75 ≤C<3.25, D represents a range of 2.25≤D<2.75, and E represents a range of E<2.25 and a flip-flop property of A, B, & C are considered passing (see ¶ 526);
there are no other examples in which the flip-flop property has a value of D or E nor an explanation of why the ranges are chosen for each of A, B, C, D, & E;
the numerical values of the flip-flop property of E33 or CE7 are not provided and thus one cannot determine where in the range 2.25≤D<2.75 CE7 falls or where in the range of 2.75 ≤C<3.25 E33 falls and thus one cannot determine if there is a critical and unexpected result obtained by the change in NVV2 or if there is instead an expected change as the value of NVP2 is changed.
as noted above, ‘476 renders obvious a range of 1 mass% ≤ NV ≤ 18 mass% because it would have been obvious to one of ordinary skill in the art at the time of filing to optimize the solids concentration of the second water-based colored paint because concentration is prima facie obvious to optimize. Generally, differences in concentration or temperature will not support the patentability of subject matter encompassed by the prior art unless there is evidence indicating such concentration or temperature is critical. "[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). MPEP 2144.05(II)(A).
applicant has not shown any evidence regarding criticality or unexpected and instead has stated that a value of D does not pass and values of NVP2≤18 %mass provide an acceptable result nor do the claims require a specific result beyond what is obtained by ‘476.
