Office Action

§102 §103
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 Claim(s) 1-12 and 15-20 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Westrum et al. 9,211,451. As to claim 1, Westrum shows an iron-type golf club head best in his fig. 35 with considered clearly shown a faceplate; a rear body enclosing a hollow interior cavity, the club head body defining a top rail, a sole, a heel end, a toe end, a front end, a rear end, a top rail periphery, a toe periphery, a heel periphery, and a sole periphery. At his reference number 430 is a sole return extending rearward from the back surface and forming at least a portion of the sole. Fig. 30 I considered to show a toe-side perimeter edge and a sole perimeter edge at 426 and at 420, the rear body is coupled to the faceplate along the faceplate perimeter forming at least a portion of the top rail. A rear body sole portion including a sole ledge coupled to the sole perimeter edge of the faceplate perimeter at 430 and forming at least a portion of the sole is considered shown in fig. 33. The rear body heel portion can be considered coupled to the heel-side perimeter edge of the faceplate perimeter and forming at least a portion of the heel end, the rear body heel portion including a hosel as shown in fig. 30. A rear wall extending from the rear body sole portion to the rear body top rail portion, and between the rear body heel portion to the heel body toe portion, to enclose the rear end of the club head is considered shown at 450 of fig. 36 that has an upper portion thickness that is substantially uniform as shown and a rear wall lower portion with a weight pad 440 coupled to and extending continuously from the rear wall upper portion interior surface at 416 wherein the weight pad forward edge is spaced from the strike face back surface as and a lower interior undercut extending rearwardly from the weight pad forward edge and between the weight pad and the sole ledge as shown in fig. 35, wherein the lower interior undercut defines a gap between the weight pad and the sole return. Claim 2 can be considered met where a plane can be defined such that the rear wall upper portion interior surface lies in a first plane. As to claims 3 and 4 a plane can be defined such that the weight pad forward edge upper region lies in a second plane and coplanar with the first plane and such both the upper and lower regions of the weight pad forward edge lie in the second plane as called for in claim 5. As to claim 6, a loft plane on the faceplate can be defined such that it is parallell to the first and second planes. As to claims 15-19, on is capable of defining the first plane such that it is offset in a perpendicular direction from the loft plane at a distance between 0.200 inches and 0.300 inches or 0.025 inches and 0.075 inches and an angle between the first plane and the second plane to be between 10 degrees and 20 degrees. As to claims 7 and 8, a second plane is capable of being defined such that it intersects a first plane and defining a faceplate a loft plane such that the first plane is parallel to the loft plane and the second plane intersects the loft plane. As to claims 9 and 10, a third plane is capable of being defined such that the lower region of the weight pad forward edge lies in it and the second plane intersects the third plane the third plane is parallel to the loft plane. As to claim 11, between 450 and 416 in fig. 35 is considered shown a shelf surface bordering an upper end of the weight pad, the shelf surface extending substantially perpendicular to the rear wall upper portion exterior surface. 416 is considered the back face as called for in claim 12. As to claim 20, the rear wall upper portion interior surface at 450 of fig. 35 can be defined such that it covers between 55% and 65% of the rear wall interior surface. Claim Rejections - 35 USC § 103 Claim(s) 13 and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Westrum. As to claims 13-and 14, while Westrum inherently has a thickness to his upper wall, he does not disclose it. To have selected between 0.025 inches and 0.060 inches would have been obvious in order to meet the desired strength and weight requirements of the club head. n Gardner v. TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984), the Federal Circuit held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to William Pierce whose telephone number is (571)272-4414 and E-mail address is bill.pierce@USPTO.gov. For emergency assistance, supervisory assistance can be obtained with Melba Bumgarner at (571)272-4709.
