Office Action

§103
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 § 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. Claims 1-7 are rejected under 35 U.S.C. 103 as being unpatentable over Nigra (1,875,484). PNG media_image1.png 576 154 media_image1.png Greyscale [AltContent: arrow][AltContent: textbox (END PORTION)]Nigra meets all of the limitations of claim 1, i.e., a bi-directional multi-grip socket bit for hexagonal fasteners comprises, a screw bit body 11 having a fastener engagement free end portion 12 and a tool engagement end portion annotated here, a plurality of flat non-adjoining longitudinally tapered fastener engagement surfaces 18 on said fastener engagement free end portion defining a defined by the tip, elongated recesses 16 joining each of said respective flat fastener engagement surfaces Fig. 3 defining spaced oppositely disposed parallel fastener engagement edges leading edge 17 and trailing edge annotated Fig. 3 in each of said spaced PNG media_image3.png 265 284 media_image3.png Greyscale [AltContent: arrow][AltContent: textbox (TRAILING EDGE)]flat fastener engagement surfaces, said elongated recess 16 extending from the fastener engagement free end top surface tip to within said tool engagement end portion 13, said elongated recess surfaces 16 are transversely concaved in fastener engagement edge to edge orientation between said respective flat fastener engagement surfaces Fig. 3, except for disclosing a hexagonal shank. Nigra discloses that the shank 11 may be of any desired cross section 02:19. It would have been obvious to one having ordinary skill in the art, before the effective date of the invention, to form a hexagonal shank in adapting the tool for hexagonally shaped workpieces, since it has been held that changing shape, dependent on work-piece parameters, involves only routine skill in the art. In re Stevens, 101 US PQ 284(CCPA1954). PNG media_image1.png 576 154 media_image1.png Greyscale [AltContent: arrow][AltContent: textbox (TAPERED END)] Regarding claim 2, PA (prior art, modified Nigra) meets the limitations, i.e., the bi-directional multi-grip socket bit for hexagonal fasteners set forth in claim 1 wherein each of said elongated recessed 16 have a vertical tapered curvilinear end portion annotated Fig. 1 between said parallel fastener engagement edges 17, trailing edge in said tool engagement end portion Fig. 1. Regarding claim 3, PA meets the limitations, i.e., the bi-directional multi-grip socket bit for hexagonal fasteners set forth in claim 1 wherein said fastener engagement free end portion has right angled transition edges from said top surface tip to said respective annularly spaced flat tapered engagement surfaces Figs. 1 and 3. Regarding claim 4, PA meets the limitations, i.e., the bi-directional multi-grip socket bit for hexagonal fasteners set forth in claim 1 wherein said fastener engagement edges 17 are at an obtuse angle to said respective flat fastener engagement surfaces Figs. 3 and 4. Regarding claim 5, PA meets the limitations, i.e., the bi-directional multi-grip socket bit for hexagonal fasteners set forth in claim 1 wherein said flat fastener engagement surfaces 16 are of equal transverse dimension Figs. 1 and 2. Regarding claim 6, PA meets the limitations, i.e., the bi-directional multi-grip socket bit for hexagonal fasteners set forth in claim 1 wherein said tool engagement portion 13 has a plurality of flat adjoining longitudinally extending surfaces e.g., lead line 13, except for a driver receiving bore in its free end. Nigra prefers a square shank 13 for readily engaging a wrench. It would have been obvious to one having ordinary skill in the art, before the effective date of the invention, to form a square receiving socket in adapting the tool for being readily engaged by a male ratchet driver, since it has been held that changing shape, dependent on work-piece parameters, involves only routine skill in the art. In re Stevens, 101 US PQ 284(CCPA1954). PNG media_image5.png 205 198 media_image5.png Greyscale Regarding claim 7, PA meets the limitations, i.e., the bi-directional multi-grip socket bit for hexagonal fasteners set forth in claim 1 wherein said elongated recess fastener engagement edges leading edge 17 and trailing edges define oppositely disposed longitudinally tapered flat engagement surfaces 16 there between Fig. 3.
