Office Action

§102
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 § 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) 1-6, 8-14, is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Knuth (USPN 7273421). Regarding claim 1, Knuth disclose a club head having a striking face 100, crown 300, sole 200, heel, toe, and hosel (See Figure 3). The sole is configured to join the club head with a shaft. The striking face has a face center and a variable thickness profile having a planar front surface and non-planar rear surface. An X-axis, Y-axis, and z-axis extend through the face center of the striking face wherein the x-axis is a horizontal axis with a positive direction toward the heel, the y-axis is a vertical axis with a positive direction toward the crown, and the z-axis being orthogonal to both the y and x axes with a positive direction toward the front to the club head. It should also be noted that the x, y, and z axes are center ed at a center of gravity of the club head. The variable thickness profile incudes a central region A having a constant thickness, a heel region B1, and a toe region B2. Figure 8A-8C outlines the striking face wherein the heel region decreases in thickness from an upper toe region towards the lower heel portion and the toe region decreases in thickness from an upper heel portion towards a lower toe portion. This is due to a transition region C1 and C2 extending between the heel and toe regions of the striking face. Regarding claim 2, Knuth discloses the central region having a V-shape (See Figure 8A). Regarding claim 3, Applicant does not disclose why having the central region having a bottom angle of 20 degrees is critical in order to attain the invention. Knuth discloses a V-shape central region wherein the bottom angle appears greater than 20 degrees due to Figure 8A showing a 90-degree line extending in the crown-sole direction such that the angle on each side of the 90-degree line appears closer to 45 degrees. Knuth discloses the club head enhancing deformation while reducing cracking and material failure wherein Knuth show the central region being V-shaped. Based on the structure set forth by Knuth, one having ordinary skill in the art would have found the bottom angle to be an obvious choice of design in order to achieve the same results set forth by Knuth. Regarding claim 4, see the above regarding claim 3. Regarding claim 5, see the above regarding claim 3. Regarding claim 6, Figure 8A shows the heel and toe complimentary angles being the same. Regarindg lcaim 7, Regarding claim 8, Knuth discloses the central region, made of the upper 110 and lower center portion 130, having a thickness of 0.05 to 0.20 inches, 1.27 to 5.08mm (See Column 4, lines 56 through 67). Regarding claim 9, see the above regarding claim 8. In addition, Knuth discloses the heel region having a thickness of 0.04 to 0.1 inch, 1.02 to 2.54mm (See Column 4, lines 56 through 67). Regarding claim 10, see the above regarding claim 8. In addition, Knuth discloses the toe region having a thickness of 0.04 to 0.1 inch, 1.02 to 2.54mm (See Column 4, lines 56 through 67). Regarding claim 11, see the above regarding claim 1. In addition, Knuth shows the central region wider at a topline of the striking face and narrows towards a bottom sole portion of the striking face. Regarding claim 12, see the above regarding claim 3. Regarding claim 13, see the above regarding claim 3. Regarding claim 14, see the above regarding claim 3. Allowable Subject Matter Claims 17-21 are allowed. Claims 7, 15, and 16 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
