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.
Claim(s) 1, 4, 6, 9, 11, & 18-27 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hodorek et al. (US PG Pub No. 2022/0241077).
Regarding Claim 1, Hodorek et al. discloses a prosthetic device (Figs. 2-7, 11, 13, 15, 18, Paragraphs [0046-0059, 0070]) comprising: an implant body (base plate 102, Figs. 4-5) having a bone-contacting surface (bottom surface 112 including any one of the porous protrusions 122, Fig. 5, Paragraph [0053]) and a peripheral bore (any one of the peripheral holes 118, Fig. 5, Paragraph [0050]); a central screw (104, Figs. 2-3 & 6, Paragraph [0047]) extending from the bone-contacting surface of the implant body (Fig. 1); and a peg (augmentation device 200, Figs. 11 & 2-3) coupled to the peripheral bore of the implant body (via 202, Fig. 2, Paragraphs [0064 & 0070]) such that the peg is configured to extend a first length beyond the bone-contacting surface of the implant body (length measured to end of tip of 226 from adjacent 122, Fig. 2) and capable of extending into a hole (344, Fig. 15, Paragraph [0067]) formed in a bone (Figs. 13 & 18, Paragraph [0070]), the hole having a first diameter and a depth (Fig. 15) that is greater than the first length such that a distal end of the peg (tip end at 226) and a bottom of the hole define a gap (Fig. 18, “The footing portion 226 has a conical shape and again presses against the surface of the bone within the defect 14. The conical bottom footing portion 226 may abut against the bone within the defect 14 over an even smaller percentage of its surface area than that of the flat bottom footing portion 204. As such, there may be less reaming and bone removal required, relative to the flat bottom footing portion 204, to prepare the surface of the bone within the defect 14.” Paragraph [0070]. Thus, a gap would exist between the tip placed at the bottom of the defect and the conical surface of 226.), wherein sides of the peg (206, Fig. 11) include an osteogenic coating (“The post 206 may include a porous surface to provide sites for bone ingrowth when inserted into a prepared glenoid cavity. The porous surface may be comprised of, for example, a porous metal structure, or a porous coating.”, Paragraph [0062]) such that the peg, inclusive of the osteogenic coating, has a second diameter (outermost diameter measured at 206 including coating, Fig. 11) capable of being greater than the first diameter of the hole (based on the size of the hole drilled, or if a hole is not drilled and 200 is , Paragraph [0082, 0085]), and wherein the distal end of the peg (226) does not include the osteogenic coating (post 206 is porous/has a porous coating whereas 226 does not) such that osteointegration is mitigated on the distal end of the peg.
Regarding Claim 4, Hodorek et al. discloses wherein a body of the peg (226, Fig. 11) has a third diameter (diameter measured at a midpoint of portion 226) that is less than the first diameter of the hole such that the osteogenic coating, and not the body of the peg is configured to interfere with the hole in the bone to aid in osseointegration (Paragraph [0070]).
Regarding Claim 6, Hodorek et al. discloses wherein the peg is capable of extending into the bone such that a distal end of the peg is in a cancellous portion of the bone (each peg is fully and structurally capable of being located in a cancellous portion of a bone when the baseplate is installed based upon the size of the defect and bone condition and anatomy at the implantation site. Paragraph [0070]).
Regarding Claim 9, Hodorek et al. discloses wherein the gap is at least one millimeter (the gap between the tip placed at the bottom of the defect and the conical surface of 226 is capable of being at least one millimeter based on the placement of the implant, the size of the defect and bone condition and anatomy at the implantation site. Paragraph [0070]).
Regarding Claim 11, Hodorek et al. discloses wherein the peripheral bore includes a threaded portion (any of the peripheral holes 118 include female threads for engaging with corresponding threads on 202, Paragraph [0063]).
Regarding Claim 18, Hodorek et al. discloses a neck adapter (coupling member 106, Figs. 2-3, 7, Paragraphs [0046-0047]) configured to be coupled to the implant body such that the neck adapter protrudes from a surface of the implant body (upper surface of 102, Fig. 2) that opposes the bone-contacting surface of the implant body.
Regarding Claim 19, Hodorek et al. discloses wherein the implant body further includes a central bore (114, Fig. 4, Paragraph [0047]).
Regarding Claim 20, Hodorek et al. discloses wherein the neck adapter is configured to be at least partially insertable into the central bore of the implant body (Fig. 2, Paragraph [0058]).
Regarding Claim 21, Hodorek et al. discloses a boss (the other two of the porous protrusions 122, Fig. 5, Paragraph [0053]) extending from the bone-contacting surface of the implant body.
Regarding Claim 22, Hodorek et al. discloses wherein the boss and the implant body are monolithic (Fig. 5).
Regarding Claim 23, Hodorek et al. discloses wherein the implant body further includes a central bore (114, Fig. 4, Paragraph [0047]), and the central screw is configured to be at least partially insertable through the central bore and at least partially through the boss (Fig. 2).
Regarding Claim 24, Hodorek et al. discloses wherein the peg and the central screw are generally parallel to each other (Figs. 2-3).
Regarding Claim 25, Hodorek et al. discloses wherein the peg is generally perpendicular to the implant body (Figs. 2-3).
Regarding Claim 26, Hodorek et al. discloses wherein the peg is shorter length-wise than the central screw (Figs. 2-3).
Regarding Claim 27, Hodorek et al. discloses wherein the implant body is a baseplate for a shoulder implant (glenosphere or liner, Figs. 19-21, Paragraphs [0033, 0041, 0046]).
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.
Claim(s) 2 & 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hodorek et al. (US PG Pub No. 2022/0241077) in view of Budge (US PG Pub No. 2015/0289984).
Regarding Claims 2 & 5, Hodorek et al. discloses the claimed invention as stated above in claim 1, except wherein the osteogenic coating of the peg comprises particulate metal, and wherein the bone-contacting surface of the baseplate implant body includes an osteogenic coating. Hodorek et al. does disclose that “The post 206 may include a porous surface to provide sites for bone ingrowth when inserted into a prepared glenoid cavity. The porous surface may be comprised of, for example, a porous metal structure, or a porous coating.” in Paragraph [0062] And ““The protrusions 122 may be comprised of a porous metal structure to provide sites for bone in growth when inserted into a prepared glenoid cavity.” in Paragraph [0053]).
Budge discloses a shoulder arthroplasty prosthesis with a biocompatible metal glenoid component and a biocompatible metal humeral component (Abstract), wherein a baseplate of the glenoid component (Figs. 3A-5) "may be made of cobalt chrome, titanium, ceramic or other suitable biocompatible metal" and wherein a bone-contacting surface thereof "may be coated in a porous ingrowth surface such as sintered metal beads, hydroxyapatite, plasma-spray, or porous tantalum to allow ingrowth of the host bone directly into the back of the body of the component or may be made directly out of an ingrowth surface such as porous tantalum or ceramic. In these Figures, a broken line seen on the side of the glenoid face (e.g., FIGS. 4, 425 and 435) indicates a boundary line between the ingrowth-coated backside and the non-coated, polished articular face. Placing porous coating on the entire back of the body of the component is important in that when fully grown-in it prevents additional shear force across any pegs on the back of the component. There may be several smaller additional pegs (e.g., three additional pegs, as shown in the Figures, and identified in the back side orthogonal view, FIGS. 4, 410, at 412, 414 and 416) protruding from the bone side of the body of the component. These may be about 3-5 mm long by about 1-3 mm in diameter. There may be one on the superior aspect of the body (412) which is directly midline, and two which may be on the inferior aspect (414, 416) and which may be offset about 2-4 mm from the vertical midline of the component. The smaller pegs may be coated in a porous ingrowth surface or may be smooth with small (less than 0.5 mm) grooves cut in them." (Paragraph [0041]).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify the porous coating of each peg and each porous bone-contacting arcuate protrusion of Hodorek et al. to comprise a particulate metal coating material such as sintered metal beads or plasma spray as taught by Budge as a common and well-known porous surface used for facilitating increased ingrowth of the host bone directly along each peg after implantation.
Claim(s) 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hodorek et al. (US PG Pub No. 2022/0241077) in view of Eickmann et al. (US PG Pub No. 2013/0218284).
Regarding Claim 7, Hodorek et al. discloses the claimed invention as stated above in claim 1, and further discloses a peripheral screw (154, Figs. 19-20, Paragraph [0046, 0052]) configured to be coupled to a second peripheral bore of the implant body (another one of the peripheral holes 118, Fig. 5, Paragraphs [0050, 0052, 0080, 0087]) such that the peripheral screw extends a second length beyond the bone-contacting surface (Figs. 19-20). Hodorek et al. does not disclose the second length being greater than the first length. It appears from Fig. 19 that 154 is longer lengthwise than the peg 200 but it is not positively disclosed.
Eickmann et al. discloses various embodiments of baseplate assembly for a joint prosthesis, wherein in Fig. 3, a baseplate is shown and includes a combination of pegs and screws inserted therethrough, wherein each screw has an overall total length which is longer than an overall total length of each peg (Fig. 3), and in Figs. 15-16, a combination of pegs (130) and a threaded screw (205) inserted through the peripheral bores of the baseplate are shown (Paragraph [0077]), and Paragraph [0077] states that "looking now at FIGS. 15 and 16, one or more pegs 160 may be replaced by a bone screw 205. More particularly, in this form of the invention, bone screw 205 preferably comprises distal threads 210 for passing through threaded bore 190 of baseplate 115 and engaging the resected tibia below the baseplate, and proximal threads 215 for engaging threaded bore 190 of baseplate 115, whereby to create downward compression between the baseplate and the bone”.
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify the overall length of each peripheral screw of Hodorek et al. be longer than the overall length of each peg as taught by Eickmann et al. in order to allow the screws to better anchor the device into the bone by creating a downward compression with the peripheral screws between the baseplate and the bone.
Response to Arguments
Applicant’s amendments, filed 03/13/26, have not overcome the objection to the drawings as the Drawing Amendment only includes a cover page and no replacement drawings attached. The Applicant’s note indicates that drawings were being filed however it appears they were erroneously not uploaded and thus the drawing objection is being upheld.
Applicant’s amendments, filed 03/13/26, have overcome the objections to claims 4 & 6.
In regards to Applicant’s arguments, filed 03/13/26, with respect to the 103 rejection of Claims 1, 4-7, 9, 11, & 21-25 over Burkhead JR in view of Eickmann, Claim 2 over Burkhead JR in view of Eickmann and Budge, and Claims 18-20 & 26 over Burkhead JR in view of Eickmann and Hodorek: The Applicant’s arguments have been fully considered but are moot in view of the new grounds of rejection based on the newly amended claims.
