Office Action

§102 §112
Detailed Action This is the first office action on the merits for US application number 19/243,900. 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 under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the one or more sensors of claim 13 line 1 and claim 15 line 12 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 Objections Claim(s) 1, 2, 13, and 15 is/are objected to because of the following informalities: Claim 1 line 1 should read “An impactor[[,]] comprising:”. Claim 2 lines 1-2 should read “the at least one direction of the translation movement of the armature component”. Claim 13 line 2 should read “detect a position of the armature component”. Claim 15 line 1 should read “An impactor[[,]] comprising:”. Claim 15 line 12 should read “determine a position of the moving armature component”. Appropriate correction is required. 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.

As to claim 3, Dittrich discloses that a change in a direction of the electric current applied to the coil (¶s 79, 114, and 117-125) is capable of changing the at least one direction of translation movement of the armature component and the striker component (¶s 72, 73, 82, and 119). As to claim 4, Dittrich discloses that the at least one direction is a forward impact direction (¶119) or a reverse impact direction (¶119). As to claim 5, Dittrich discloses that the object includes at least one of: a tool, an implant, or any combination thereof (¶66 discloses use with a rasp or broach, ¶70 discloses tools, a first rasp, and a second rasp, ¶98 discloses an instrument, ¶103 discloses an impact tool, ¶104 discloses an impact instrument). As to claim 6, Dittrich discloses that the translation movement of the striker body is capable of use for positioning an implant in a bone (¶s 72 and 78 disclose driving a tool into bone) and/or removal of the implant from the bone (¶s 73 and 78 disclose an extraction force to remove a tool from bone). As to claim 7, Dittrich discloses that the coil is capable of receiving one or more current pulses to trigger translation of the armature component and the striker body (¶s 79, 114, and 117-125). As to claim 8, Dittrich discloses that the one or more current pulses that the coil is capable of receiving include a high current pulse and a low current pulse (¶s 79, 114, and 117-125), wherein the low current pulse is smaller than the high current pulse (¶s 79, 114, and 117-125). As to claim 9, Dittrich discloses that a duration of application of the high current pulse that the coil is capable of receiving is longer than a duration of application of the low current pulse that the coil is capable of receiving (¶s 79, 114, and 117-125). As to claim 10, Dittrich discloses that application of the low current pulse that the coil is capable of receiving is capable of preventing movement of the armature component and the striker body in a direction opposite to a direction of movement of the armature component and the striker body resulting from application of the high current pulse (¶s 79, 114, and 117-125). As to claim 11, Dittrich discloses that the high current pulse and the low current pulse that the coil is capable of receiving are applied intermittently (¶s 79, 114, and 117-125). As to claim 12, Dittrich discloses that the spacer is capable of limiting a translation distance of the distal end of the striker body within the interior of the strike chamber (Figs. 4B-5B, and 9A-9C, ¶104).
