Office Action

§102 §103
Detailed Action This office action is for US application number 18/280,139 evaluates the claims as filed on November 10, 2025. 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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on December 12, 2025 and November 10, 2025 has been entered. Response to Arguments Applicant's arguments filed December 12, 2025 and November 10, 2025 have been fully considered but they are not persuasive. The rejections in this office action have been amended to address the amended claims. Examiner asserts that Hafeli teaches all the newly-amended limitations and is capable of performing the functions as claimed. Examiner directs Applicant to the rejection below for a more in-depth description of the limitations. With regards to Applicant’s argument that Hafeli discloses a cross-section with an inner diameter and a key/tab instead of teaching a quadrilateral shape as both means prevent rotation but the claimed quadrilateral cross-sections provide for increase resistance to rotational forces compared to the circular cross-section interrupted by a tab or key (Remarks p. 9-10), Examiner notes that Applicant appears to be applying a narrower interpretation to “quadrilateral” shape/cross-section than is warranted based on the BRI of the claim language. That is, it does not appear that Applicant has not provided a specific definition for quadrilateral and the ordinary definition includes “having four sides” (https://www.merriam-webster.com/dictionary/quadrilateral). Thus, Hafeli discloses a cross-section of the central cavities and a cross-section of the central support member are quadrilateral (Fig. 7) capable of preventing rotation of the cutting members around the longitudinal axis (col. 4 lines 28-32). In the interest of clarity, Examiner has annotated Hafeli Fig. 7 to label each of the four sides of each cross-section below. Examiner suggests that it appears that Applicant may be intending that the quadrilateral cross-section is formed by or defined by four substantially linear sides and amending accordingly. PNG media_image1.png 469 722 media_image1.png Greyscale Priority Should applicant desire to obtain the benefit of foreign priority under 35 U.S.C. 119(a)-(d) prior to declaration of an interference, a certified English translation of the foreign application must be submitted in reply to this action. 37 CFR 41.154(b) and 41.202(e). Failure to provide a certified translation may result in no benefit being accorded for the non-English application. 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. (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) 1, 2, 5, 7-10, 12, 16, 18, 22-25, and 27-29 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hafeli (US 5,006,121).

PNG media_image1.png 469 722 media_image1.png Greyscale As to claim 27, Hafeli discloses a method (Figs. 1-7, col. 4 lines 14-42) capable of producing a surgical tool (Figs. 1-7, col. 4 lines 25-37), the method comprising: - providing a plurality of cutting members (“individual broach plates” of col. 2 line 65 and shown individually in Figs. 6 and 7, Figs. 1 and 3-7, col. 4 lines 25-37), wherein each cutting member of the plurality of cutting members is distinct and separate from other cutting members of the plurality of cutting members (shown individually in Figs. 6 and 7, Figs. 1 and 3-7, col. 4 lines 25-37); and - disposing each of said cutting members in contact with an adjacent cutting member (Fig. 1) according to a determinate sequence along a longitudinal axis (vertical axis along 30 as shown in Fig. 2, Figs. 1 and 2, col. 2 line 55 – col. 3 line 5, col. 3 lines 27-32 and 60-65, col. 4 lines 4-14 and 25-37) in order to make up a cutting unit (26, 28, Fig. 1), wherein each of said cutting members comprises a central cavity (50, 38, Fig. 7, col. 3 lines 25 and 27-32, col. 4 lines 25-37) substantially coaxial to said longitudinal axis (as defined, Figs. 1-3 and 7), wherein the central cavities of said cutting members collectively define a central channel (channel that receives 30 and 52, Figs. 1-3 and 7, col. 3 lines 25 and 27-32, col. 4 lines 25-37), wherein the central cavity of each cutting member is complementary in shape with the adjacent cutting member along the longitudinal axis (Figs. 1-3 and 7, col. 3 lines 25 and 27-32, col. 4 lines 25-37) in order to give the central channel a desired shape (Fig. 1, co1. 4 lines 4-14), the central channel comprising a first tapered portion (Figs. 1, 6, and 7, col. 3 lines 23 and 27-32) and a second rectilinear portion (50, Fig. 7, col. 4 lines 28-29), wherein said surgical tool further comprises a central support member (32) disposed inside said central channel (Figs. 1-3 and 7, col. 3 lines 25 and 27-32, col. 4 lines 25-37) and capable of giving structural rigidity to said cutting unit (Fig. 1, col. 3 lines 61-66), wherein each cutting member comprises a metal plate (Figs. 6 and 7, col. 1 lines 49-50) of a determinate thickness (Fig. 6, col. 4 lines 4-10) and has lateral walls inclined in a direction of the thickness by an angle α with respect to the longitudinal axis (Fig. 6, col. 3 lines 51-60), wherein said angle α is variable depending on a considered side of the cutting member (Fig. 1, col. 3 lines 51-60, col. 4 lines 4-10 and 43-48), wherein said angle α is between about 10° and about 40° (Fig. 6, col. 3 lines 51-60), wherein a cross-section of the central cavities and a cross-section of the central support member are quadrilateral (see illustration of Fig. 7, Fig. 7) capable of preventing rotation of the cutting members around the longitudinal axis (col. 4 lines 28-32). As to claim 28, Hafeli discloses - producing, or having available, said central support member complementary in shape with said central channel (Figs. 1-3 and 7, col. 3 lines 25 and 27-32, col. 4 lines 25-37); and - inserting each of said cutting members on said central support member in accordance with said determinate sequence (Fig. 1, col. 3 lines 61-66). As to claim 29, Hafeli discloses making said cutting members by one of the following processes: laser cutting, milling, or additive manufacturing (col. 4 lines 15-42). 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 of this title, 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. Claim(s) 10, 11, 13, and 26 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hafeli. As to claim 10, Hafeli discloses the invention of claim 7 and appears to disclose that the cutting member at a first end of the cutting unit is mechanically connected by welding or gluing to the first element (col. 5 lines 10-13), but does not explicitly state that the cutting member at a first end of the cutting unit is mechanically connected by welding or gluing to the first element. Hafeli teaches that if desired broach plates may be cemented to each other, whether a curved or straight mandrel is used, to prevent any possible shifting of the broach plates with respect to each other and that broaches may be fabricated in accordance with the present invention by cementing the broach plates to each other to form a rigid stack (col. 5 lines 10-20). One of ordinary skill in the art before the effective filing date of the claimed invention would have been motivated to specify that the cutting member at a first end of the cutting unit and the first element as disclosed by Hafeli are mechanically connected by welding or gluing as taught by Hafeli in order to prevent any possible shifting of the cutting member at the first end of the cutting unit (Hafeli col. 5 lines 10-13). As to claim 11, Hafeli discloses the invention of claim 7 as well as the first element is disposed at the first end of said central support member (as defined, Figs. 1 and 2). Hafeli further discloses that once the individual cutting members have been completed by the formation of the final cutting edge, they are stacked in proper order on the central support member, the assembly being clamped in position by rotating the second element to thread the first end of the central support member into the first element (col. 3 lines 61-66). Hafeli is silent to the first element is made in a single body with said central support member. That is, Hafeli discloses the claimed invention except for the first element being threadedly connected to the central support member with the second element made in a single body with said central support member to clamp the assembly of cutting members. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have the second element being threadedly connected to the central support member with the first element made in a single body with said central support member, since rearranging parts of an invention involves only routine skill in the art and provides a known clamping of the cutting members (Hafeli col. 3 lines 61-66). In other words, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to construct the second element and the central support member as separate connectable structure, since constructing a formerly integral structure in various elements involves only routine skill in the art and provides a known clamping of the cutting members (Hafeli col. 3 lines 61-66). Further, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to specify that the first element and said central support member are formed as a single unit, since forming in one piece an article which has formerly been constructed as an integral structure involves only routine skill in the art and provides a known clamping of the cutting members (Hafeli col. 3 lines 61-66). As to claim 13, Hafeli discloses the invention of claim 7 as well as the first end of the central support member comprises a coupling portion (Fig. 2, col. 2 line 67 – col. 3 line 2, col. 3 lines 64-66) capable of being mechanically and reversibly connected to the first element (Fig. 2, col. 2 line 67 – col. 3 line 2, col. 3 lines 64-66) capable of allowing disconnection of the first element from the central support member for replacing the cutting unit (Figs. 1 and 2, col. 2 line 67 – col. 3 line 2, col. 3 lines 64-66). That is, Hafeli discloses that once the individual cutting members have been completed by the formation of the final cutting edge, they are stacked in proper order on the central support member, the assembly being clamped in position by rotating the second element to thread the first end of the central support member into the first element (col. 3 lines 61-66). Hafeli is silent to the second end of the central support member comprises a coupling portion configured to be mechanically and reversibly connected to the second element to allow disconnection of the second element from the central support member for replacing the cutting unit. That is, Hafeli discloses the claimed invention except for the first element being threadedly connected to the central support member with the second element made in a single body with said central support member to clamp the assembly of cutting members. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have the second element being threadedly connected to the central support member with the first element made in a single body with said central support member, since rearranging parts of an invention involves only routine skill in the art and provides a known clamping of the cutting members (Hafeli col. 3 lines 61-66). Alternately, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to construct the second element and the central support member as a threadedly connectable separate structure, since constructing a formerly integral structure in various elements involves only routine skill in the art and provides a known clamping of the cutting members (Hafeli col. 3 lines 61-66). As to claim 26, Hafeli discloses the invention of claim 24. Hafeli is silent a plurality of protrusions made on lateral walls of each cutting member, or, alternatively, in correspondence with a lateral edge. Hafeli, in an alternate embodiment, teaches a similar tool (Figs. 1-6 and 8, col. 4 lines 50-62) comprising cutting members (Fig. 8) comprising at least one cutting element (Fig. 8) such that the cutting elements comprise a plurality of protrusions (Fig. 8) made on lateral walls of each cutting member (Fig. 8, col. 4 lines 50-62), or, alternatively, in correspondence with a lateral edge (Fig. 8, col. 4 lines 50-62). One of ordinary skill in the art before the effective filing date of the claimed invention would have been motivated to modify the cutting elements as disclosed by Hafeli to have protrusions as taught by Hafeli, in an alternate embodiment, in order to reduce the total length of active cutting edge to reduce the force required to insert the broach (Hafeli col. 4 lines 45-52) and enable protrusion position to be staggered between cutting members so that the cutting element of two or more cutting members is combined to define the desired bone opening for the corresponding axial position or positions of the cutting members on the tool assembly (Hafeli col. 4 lines 53-57).
