Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Claim Rejections - 35 USC § 103 The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1, 2, 6, 10-14, 18 and 19 is/are rejected under pre-AIA 35 U.S.C. 103(a) as being obvious over Chen (USPN 7169062) in view of Wada (USPN 8465379). Regarding claim 1, Chen discloses a ball striking device having a ball striking plate. The ball striking plate has a front surface and a rear surface and includes a geometric center, a desired contact region, and a perimeter. Chen also discloses one or more spoke-like reinforcement ribs located on the rear surface of the ball striking plate and extending away from the geometric center toward the perimeter. Each spoke-like reinforcement rib has a cross-sectional shape, height, width, and cross-sectional area (See Figure 3-9). Applicant does not disclose why the dimension and shape of the spoke-like reinforcement ribs are critical in order to attain the invention. According to the applicant, the spoke-like reinforcement ribs can have a maximum height of 2mm, and maximum width of 3mm, and a maximum cross-section of 1mm² (See Paragraphs 61, 62, and 64 of the specification). Chen does note that the thickness (height) of the ribs can range from 0 to 30mm (See Column 4, lines 55 through 67) and that the width can vary. Chen does not disclose a second spoke-like rib having a length that does not reach the perimeter. Wada disclose a club head having spoke-like ribs on the rear of the ball striking plate wherein a second set of spoke-like ribs 16a and 16b extend toward the perimeter but do not reach the perimeter (See Figures 1 and 2). Wada notes that the spoke-like rib configuration maintains the COR but improves the strength of the club head (See Summary of the Invention). One having ordain skill in the art would have found it obvious to have a set of spoke-like ribs that do not reach the perimeter of the ball striking plate, as taught by Wada, in order to strengthen the ball striking plate while maintaining COR. Regarding claim 2, Applicant does not disclose why having curved ribs are critical in attaining the invention. Chen discloses a club head having a ball striking plate with spoke-like reinforcement ribs wherein the ribs gradually increase in thickness (See Figure 7). Though Chen does not show the ribs being curved, curved ribs would gradually increase in thickness also. Therefore, one having ordinary skill in the art would have found the curved profile of the ribs to be an obvious choice of design. The ribs disclosed by Chen would perform equally as well since it reinforces the ball striking plate and places more flexure emphasis on the geometric center of the ball striking plate. Regarding claim 6, Chen discloses at least one of the spoke-like reinforcement rips being a linear element (See Figure 2, 3 and 7). Regarding claim 10, Chen discloses that having a thickened portion with an elevated area on the rear surface of the ball striking plate is well known. This is evident by Figure 1 and the description of the related art disclosed by Chen. Further Chen also discloses that the disclosed invention and the invention in Figure 1 have similar configuration and function (See Column 3, lines 33 through 40). Based on the above, one having ordinary skill in the art would have found the elevated thickened area to be an obvious modification. Regarding claim 11, see the above regarding claim 1. Regarding claim 12, see the above regarding claim 1. Regarding claim 13, see the above regarding claim 1. Regarding claim 14, see the above regrading claim 2. Regarding claim 18, see the above regarding claim 1. Regarding claim 19, see the above regarding claim 2. Response to Arguments Applicant’s arguments with respect to claim(s) 1, 2, 6, 10-14, 18 and 19 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
