Office Action

§103
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Status of Claims Claims 1-16 are pending. 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, 7, 9 and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Omaha et al (“Omaha”) (US 2009/0221387) in view of Omaha et al (“Omaha 2”) (US 2010/0093466). Re claim 1, Omaha discloses a golf ball (2) comprising a spherical core (4), and an outermost cover (6) positioned outside the intermediate layer (as modified below) and having a plurality of dimples (10) formed thereon (Fig. 1), wherein the spherical core (4) is formed from a rubber composition ([0027]) containing a base rubber ([0027]), a co-crosslinking agent ([0028]), and a crosslinking initiator ([0031]), the base rubber ([0027]) contains a natural rubber ([0027]), and an occupation ratio ([0086]) of a total area of the plurality of dimples (10) in a surface area of a virtual sphere that is assumed to have no dimples on the outermost cover (8) is 45% or more and less than 75% ([0086] disclosing less than 75%, as well as 73%, being more than 45% and less than 75%), but fails to disclose an intermediate layer covering the spherical core ([0116]). However, Omaha 2 discloses an intermediate layer covering the spherical core. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the golf ball of Omaha with an intermediate layer covering the spherical core as disclosed by Omaha 2 in order to balance distance and control via managing spin rates ([0028]). Re claim 7, Omaha discloses the golf ball according to claim 1, but fails to disclose wherein a slab hardness of an intermediate layer composition forming the intermediate layer is greater than a slab hardness of a cover composition forming the outermost cover. However, Omaha 2 discloses wherein a slab hardness of an intermediate layer composition forming the intermediate layer is greater than a slab hardness of a cover composition forming the outermost cover ([0090]). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the golf ball of Omaha wherein a slab hardness of an intermediate layer composition forming the intermediate layer is greater than a slab hardness of a cover composition forming the outermost cover as disclosed by Omaha 2 in order to provide ball speed while maintaining high spin control. Re claim 9, Omaha discloses the golf ball according to claim 1, Omaha 2 discloses wherein an intermediate layer composition ([0090]) forming the intermediate layer ([0090]) is a resin composition ([0022]) containing an ionomer resin ([0022]) as a base resin ([0022]), and a slab hardness of the intermediate layer composition forming the intermediate layer is 50 or more in Shore D hardness ([0055]). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the golf ball of Omaha wherein an intermediate layer composition forming the intermediate layer is a resin composition containing an ionomer resin as a base resin, and a slab hardness of the intermediate layer composition forming the intermediate layer is 50 or more in Shore D hardness as disclosed by Omaha 2 in order to provide ball speed while maintaining high spin control. Re claim 16, Omaha discloses the golf ball according to claim 9, but fails to disclose wherein the slab hardness of the intermediate layer composition forming the intermediate layer ranges from 50 to 74 in Shore D hardness. However, Omaha 2 discloses wherein the slab hardness of the intermediate layer composition forming the intermediate layer ranges from 50 to 74 in Shore D hardness ([0055]). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the golf ball of Omaha wherein the slab hardness of the intermediate layer composition forming the intermediate layer ranges from 50 to 74 in Shore D hardness as disclosed by Omaha 2 in order to provide ball speed while maintaining high spin control. Claim(s) 2-5, 8, 10-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Omaha et al (“Omaha”) (US 2009/0221387) in view of Omaha et al (“Omaha 2”) (US 2010/0093466) and Sakamine et al (“Sakamine”) (US 2015/0273277). Re claim 2, Omaha discloses the golf ball according to claim 1, but fails to disclose wherein a center hardness (H0) of the spherical core, a hardness (H2.5) at a point having a radial distance of 2.5 mm from a center of the spherical core, a hardness (H5.0) at a point having a radial distance of 5.0 mm from the center of the spherical core, a hardness (H7.5) at a point having a radial distance of 7.5 mm from the center of the spherical core, a hardness (H10) at a point having a radial distance of 10 mm from the center of the spherical core, a hardness (H12.5) at a point having a radial distance of 12.5 mm from the center of the spherical core, a hardness (H15) at a point having a radial distance of 15 mm from the center of the spherical core, and a surface hardness (Hs) of the spherical core satisfy a relationship of HO<H2.5<H5.o<Hr.5<Hlo<HI2.5<H15<Hs, and the center hardness (HO) of the spherical core is 70 or less in Shore C hardness.
