Office Action

§102
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 . Previous Indication of Allowable Subject Matter The indicated allowability of claim 8 is withdrawn in view of (Chaconas). Claim Rejections - 35 USC § 102 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claim(s) 8 is/are rejected under 35 U.S.C. 102(A)(1) as being anticipated by US 2007/0289426 A1 to (Chaconas). Noting the embodiment of Figs. 7-16, (Chaconas) discloses a fastener removal tool (bolt remover 110), the tool including: a main body 112; a receiving hole (axial bore 124 – Figs. 11 and 12) formed from a first outer side (body second end 118 to body first end 116) of the main body in a first direction (axial direction); and a plurality of teeth (axial ribs 128) each projecting from the main body 112 in a second direction perpendicular to the first direction (direction…radially; para. [0050]), projecting inward in the receiving hole 124, and extending in a longitudinal direction (axial direction along longitudinal axis 114), the longitudinal direction and the second direction being contained in a same plane; wherein each of the plurality of teeth 128 is tapered in the first direction (axial direction – e.g., Figs. 12 and 15A); wherein each of the plurality of teeth is tapered in the second direction (radial direction – e.g., Figs. 15, 15A – angle ε; para. [0053]). PNG media_image1.png 746 534 media_image1.png Greyscale Allowable Subject Matter Claims 1-4 and 11-16 are allowable. Claims 9 and 10 are objected to as being dependent upon a rejected base claim, but would be allowable if claim 9 is rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: regarding claim 1, that each of the plurality of teeth is tapered in the first direction; each of the plurality of teeth includes two flat side surfaces extending from the main body and an arcuate ridge surface connected to and between the two flat side surfaces; and, regarding claim 9, that each of the plurality of teeth includes two flat side surfaces extending from the main body and an arcuate ridge surface connected to and between the two flat side surfaces, is considered to be novel and non-obvious in view of the prior art of record. Conclusion Reconsideration of the prior art of record in response to the amendment filed 30 April 2026 has revealed that the second embodiment (Figs. 7-16) of the bolt remover of (Chaconas) anticipates claim 8. Claims 1-4 and 11-16 are allowable, and claim 9 if amended to include all of the limitations of claim 8 would be allowable.
