Claim Rejections - 35 USC § 102
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.
Claim(s) 1-3 and 5-14 is/are rejected under 35 U.S.C. 102(a)(a) as being anticipated by Umezawa et al (2013/0196790). Claim 1, Umezawa discloses a golf ball comprising a spherical core, an inner cover layer (applicant’s intermediate layer) positioned outside the spherical core , and an outermost cover positioned outside the inner cover layer and having a plurality of dimples (fig 1), wherein a material hardness Hm (Shore D hardness) of the inner cover layer is 62, a material hardness Hc (Shore D hardness) of the outermost cover is 48, a thickness Tc (mm) of the outermost cover is 1.0 mm (table 9, ex 1), and a total lower volume Vi (mm3) of the plurality of dimples satisfy, Vi>365 and (Hc/Tc)×(Hm/Vi)≤7.5. The total lower dimple volume Vi (fig 2) is 464.4 mm3 (table 3) [(40x1.53) + (184x1.31) + (96x0.73) + (32x1.72) + (16x1.45) + (16x0.62) + (8x0.49)]. Solving the equation [(48/1) x (62/464.4) = 6.4 ≤7.5]. Claims 2-3, Vi = 464.4 mm3 (table 3). Claim 5, the outermost cover contains a polyurethane as a resin component (table 2). Claim 6, the value (Hc/Tc) (48/1= 48) is 30 or more and 75 or less (table 9, ex. 1). Claim 7, the value (Hm/Vi) (62/464.4= 0.13) is 0.08 or more and 0.22 or less (table 9, ex. 1). Claim 8, a surface hardness Hs of the spherical core is 57 Shore D or 86 Shore C (table 9, ex 1). Claim 9, a center hardness Ho of the spherical core is 42 Shore D hardness or 66 Shore C hardness (table 9, ex. 1). Claim 10, the material hardness Hm of the inner cover layer ranges from 50 to 80 in Shore D hardness [0050]. Claim 11, a thickness Tm of the inner cover layer ranges from 1.0 mm to 3.0 mm [0051]. Claim 12, the material hardness Hc of the outermost cover ranges from 35 to 60 in Shore D hardness [0053]. Claim 13, the thickness Tc of the outermost cover ranges from 0.5 mm to 3.0 mm [0054]. Claim 14, Vi = 464.4 mm3 (table 3).
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.
Claim(s) 1-16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Watanabe et al. (2023/0082849) in view of Umezawa et al. (2013/0196790). Claim 1, Watanabe discloses a golf ball comprising a spherical core, an intermediate layer positioned outside the spherical core, and an outermost cover positioned outside the intermediate layer and having a plurality of dimples (fig 1). Watanabe further discloses a material hardness Hm (Shore D hardness) of the intermediate layer of 60 [0078], a material hardness Hc (Shore D hardness) of the outermost cover of 35 [0089], and a thickness Tc (mm) of the outermost cover is 1.0 mm [0091]. Watanabe does not disclose a dimple volume greater than 365. Umezawa teaches a three-layer golf ball comprising a total lower dimple volume (fig 2) of 464.4 mm^3 (table 3) [(40x1.53) + (184x1.31) + (96x0.73) + (32x1.72) + (16x1.45) + (16x0.62) + (8x0.49)]. Solving for the equation using the values of Watanabe, as shown above, in view of the total dimple volume of Umezawa, the value is 4.5. (Hc/Tc)×(Hm/Vi)≤7.5 [(35÷1) x (60 ÷ 464.4)= 4.5]. One of ordinary skill in the art would have modified the dimple volume for the desired flight performance. Claims 2-3, Umezawa teaches a total lower dimple volume (fig 2) of 464.4 mm3 (table 3). Claim 4, Watanabe discloses the surface hardness (Shore C hardness) of the spherical core < a surface hardness (Shore C hardness) of the intermediate layer > a surface hardness (Shore C hardness) of the golf ball is satisfied (87.4 < 98 >87) (table 6, ex. 1). Claim 5, Watanabe discloses the outermost cover contains a polyurethane as a resin component [0093]. Claim 6, Watanabe discloses the value (Hc/Tc) is 35 (35/1) (see above). Claim 7, Watanabe discloses the value (Hm/Vi) is 0.13 (60/464.4) (see above). Claim 8, Watanabe discloses the surface hardness H100 of the spherical core ranges from 83-94 in Shore C hardness [0056]. Claim 9, Watanabe discloses the center hardness H0 of the spherical core ranges from 62-72 in Shore C hardness [0064]. Claim 10, Watanabe discloses the material hardness Hm of the intermediate layer ranges from 60-72 in Shore D hardness [0078]. Claim 11, Watanabe discloses a thickness Tm of the intermediate layer ranges from 0.9 mm to 1.5 mm [0080]. Claim 12, Watanabe discloses the material hardness Hc of the outermost cover ranges from 35-60 in Shore D hardness [0089]. Claim 13, Watanabe discloses the thickness Tc of the outermost cover ranges from 0.3 mm to 1.2 mm [0091]. Claim 14, Umezawa teaches a total lower dimple volume (fig 2) of 464.4 mm3 (table 3). Claim 15, Watanabe discloses a difference (Hms-Hcs) between a surface hardness Hms of the intermediate layer and a surface hardness Hcs of the golf ball is more than 0; (98-87) (table 6, ex. 1). Claim 16, Watanabe discloses a difference (Hms-Hs) between a surface hardness Hms of the intermediate layer and a surface hardness Hs of the spherical core is more than 0; (98-87.4) (table 6, ex. 1). One of ordinary skill in the art would have modified the dimple volume for the desired flight performance.
