Office Action

§102 §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 . Election/Restrictions Claims 1-2 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 3/2/2026. Applicant's arguments of Species requirement in the reply is acknowledged and is found persuasive. The species restriction is withdrawn. Applicant’s election without traverse of Group II, claims 3-10, in the reply is acknowledged. Specification The disclosure is objected to because of the following informalities: In para. 118: “the clamping rotation device is configured to cutter each workpiece to be machined” should be corrected such that “configured to cutter” is replaced with -- configured to cut--Appropriate correction is required. Drawings 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 “conventional equipment” (claim 1) 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. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. 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 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 3-10 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 3 recites the limitation " the alloy main drill structure is configured for main drilling wood ". It is unclear what “main drilling wood” means. Claim 3 recites the limitation “a conventional equipment”. It is unclear what this element is since the specification does not describe what it is. This makes the scope unclear. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 3 is/are rejected under 35 U.S.C. 102a1 and a2 as being anticipated by Durfee (PGPub 2013/0189044). Re Claim 3, as best understood, Durfee discloses a production process of a woodworking drill, the woodworking drill, comprising: a cutter body; wherein an outer side wall of the cutter body defines a plurality of chip discharge slots 12 that are spirally disposed, and the plurality of chip discharge slots are disposed circumferentially about a center axis of the cutter body; a cutter shank, connected to an end of the cutter body; and an alloy main drill structure (at 20a/16), arranged at another end of the cutter body back away from the cutter shank; wherein a plurality of secondary cutting edges are formed on the outer side wall of the cutter body by the plurality of chip discharge slots, and the alloy main drill structure is configured for main drilling wood (Fig. 1-9; para. 18-31), wherein the production process comprises the following steps: S1: processing the cutter body, the cutter shank, and the alloy main drill structure with a conventional equipment (para. 28-31); S2: machining out the plurality of chip discharge slots with a chip slot machining apparatus (para. 28-31); and S3: welding the alloy main drill structure to the cutter body (para. 28-31). Allowable Subject Matter Claims 4-10 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 and if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims.
