Office Action

§102 §103 §112
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 . Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(4) because reference character “118” has been used to designate both locking sleeve and ball bearings. The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the edge of the pocket (claim 3) must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Objections Claims 1 and 3 are objected to because of the following informalities: in line 11 of claim 1, “a number of a number” and in line 1 of claim 3, “wherein the one of the one of the one or more pockets” are objected to. Appropriate correction is required. Claim 3 is objected to for extra period at the end of the claim. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 8 and 11 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 8 recites the for the locking tabs and locking recesses not to be alignable when the locking pin is not disposed, which appears to be an error, since as in claim 7, the tabs and recesses are alignable when the pin is not disposed. Similarly claim 11, recites for the tabs and recesses to be alignable when pin is not disposed and further recites for the tabs and recesses not to be alignable when the pin is not deposed, which ambiguous in eliminating an element (pin). 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. Claims 1-4 and 6-14 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Rinner (5,848,680).

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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1-14 are rejected under 35 U.S.C. 103 as being unpatentable over Gauthier (6,948,605) in view of Rinner (5,848,680). Gauthier`500 meets all of the limitations of claim 1, i.e., a ratcheting mechanism for a tool, the ratcheting mechanism comprising: PNG media_image8.png 417 477 media_image8.png Greyscale PNG media_image9.png 380 398 media_image9.png Greyscale PNG media_image12.png 426 660 media_image12.png Greyscale a) a housing 20 including a central passage 26, one or more pawls 32 moveably positioned within the housing adjacent the central passage, 58 spaced from the central passage Fig. 4 and including a 56 disposed therein; b) a gear 44 positioned within the central passage and selectively engageable with the one or more pawls Fig. 4; and c) a reverse cap 14 engaged with the housing over the gear Fig. 5, the reverse cap including a top wall including an interior surface 72 having one or more pawl engaging pockets 70 formed therein, a peripheral side wall extending Fig. 5 outwardly therefrom, wherein the number of locking tabs 47, 48, 50 are alignable with and insertable through the number of locking recesses between 42 and rotatable with respect to the housing bayonet connection, and wherein the locking pin 56 is positionable within one of the one or more pockets 70 to function as a stop for the rotation of the reverse cap 14 relative to the housing 20 06:10-14, except for a number of locking recesses formed along a perimeter of the housing with a number of locking tabs formed along a perimeter of the side wall, a biased locking pin to prevent disengagement of the reverse cap from the housing.
