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) 1-2, 4-9 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Koay et al. (US 2018/0256221), hereinafter “Koay”.
Regarding claim 1, Koay discloses a periprosthetic plate (100), comprising: a proximal segment (102 with 136) having a top portion (120) and an end portion (108) with at least two curved hooks (106) that are capable of passing through a patient's abductor muscles and rest medially on a tip of a patient's greater trochanter (GT) (¶12, 14), wherein the proximal segment includes a plurality of recessed bone screw holes (110, 114, 116, 118) for attachment to a patient's femur with bone screws, and wherein each of the two curved hooks has a distal end that tapers to a point (FIG. 3).
Regarding claim 2, Koay discloses the periprosthetic plate according to Claim 1, wherein the proximal segment includes a hook portion (102) having the at least two curved hooks and an attachment portion (136).
Regarding claim 4, Koay discloses the periprosthetic plate according to Claim 1, wherein the plurality of recessed bone screw holes are in sets of two recessed bone screw holes that are parallel to each other (FIG. 1).
Regarding claim 5, Koay discloses the periprosthetic plate according to Claim 4, wherein the plurality of recessed bone screw holes are in two sets of at least two recessed bone screw holes that are parallel to each other (FIG. 1).
Regarding claim 6, Koay discloses the periprosthetic plate according to Claim 1, further comprising a distal segment or shaft (138) that is attached to or is integral with the proximal segment (FIG. 2).
Regarding claim 7, Koay discloses the periprosthetic plate according to Claim 6, wherein the proximal segment includes a hook segment (102) attached to the at least two curved hooks and an attachment segment (136).
Regarding claim 8, Koay discloses the periprosthetic plate according to Claim 7, wherein the hook segment includes a first plurality of recessed bone screw holes (110), the attachment segment includes a second plurality of recessed bone screw holes (114, 116, 118), and the distal segment or shaft includes a third plurality of recessed bone screw holes (142).
Regarding claim 9, Koay discloses the periprosthetic plate according to Claim 8, wherein the first plurality of recessed bone screw holes are in sets of two and parallel to each other (FIG. 2), the second plurality of recessed bone screw holes are in sets of two and parallel to each other (FIG. 2) and the third plurality of recessed bone screw holes are staggered from side-to-side along the longitudinal length of the distal segment or shaft (FIG. 2).
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) 3, 10, 14-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Koay in view of Lorenz et al. (US 2010/0234896), hereinafter "Lorenz".
Regarding claim 3, Koay discloses the periprosthetic plate according to Claim 1, wherein “the head portion have any number of bone fixation element receiving openings extending therethrough in any of a variety of spacings and configurations” (¶16), but it silent regarding wherein the plurality of recessed bone screw holes are beveled so that any inserted bone screws do not extend above the top portion of the proximal segment. Lorenz discloses a periprosthetic plate (120, FIGS. 14-19) comprising a proximal segment with at least two curved hooks (121, 122), wherein the proximal segment includes a plurality of recessed bone screw holes wherein the plurality of recessed bone screw holes are beveled (¶40) so that any inserted bone screws do not extend above the top portion of the proximal segment. It would have been obvious to one having ordinary skill in the art to combine beveled bone screw holes with the bone screw holes of Koay, so that bone screws do not extend above the top portion of the plate. In this case, one would utilize beveled bone screw holes in the plate of Koay.
Regarding claim 10, Koay discloses the periprosthetic plate according to Claim 9, except wherein the first plurality of recessed bone screw holes, the second plurality of recessed bone screw holes, and the third plurality of recessed bone screw holes are beveled so that any inserted bone screws do not extend above the top portion of the proximal segment. Lorenz discloses a periprosthetic plate (120, FIGS. 14-19) comprising a proximal segment with at least two curved hooks (121, 122), wherein the proximal segment includes a plurality of recessed bone screw holes wherein the plurality of recessed bone screw holes are beveled (¶40) so that any inserted bone screws do not extend above the top portion of the proximal segment. It would have been obvious to one having ordinary skill in the art to combine beveled bone screw holes with the bone screw holes of Koay, so that bone screws do not extend above the top portion of the plate. In this case, one would utilize beveled bone screw holes in the plate of Koay.
Regarding claims 14-15, Koay discloses a periprosthetic plate (100), comprising: a hook segment (102) having a top portion (120) and an end portion (108) with at least two curved hooks (106), each curved hook tapering to a point (FIG. 3), the at least two curved hooks are capable of passing through a patient's abductor muscles and rest medially on a tip of a patient's greater trochanter (GT) (¶12), wherein the hook segment includes a first plurality of recessed bone screw holes (110) that are in sets of two recessed bone screw holes that are parallel to each other (FIG. 2); and an attachment segment (136) that is attached or integral to the hook segment and includes a second plurality of recessed bone screw holes (114, 116, 118) that are in sets of two and parallel to each other (FIG. 2) and are in sets of two recessed bone screw holes that are parallel to each other (FIG. 2), further comprising a distal segment or shaft (138) that is attached to or integral with the attachment segment and includes a third plurality of recessed bone screw holes (142) that are staggered from side-to-side along the length of the distal segment or shaft (FIG. 2). However, Koay is silent regarding the bone screw holes being beveled. Lorenz discloses a periprosthetic plate (120, FIGS. 14-19) comprising a proximal segment with at least two curved hooks (121, 122), wherein the proximal segment includes a plurality of recessed bone screw holes wherein the plurality of recessed bone screw holes are beveled (¶40) so that any inserted bone screws do not extend above the top portion of the proximal segment. It would have been obvious to one having ordinary skill in the art to combine beveled bone screw holes with the bone screw holes of Koay, so that bone screws do not extend above the top portion of the plate. In this case, one would utilize beveled bone screw holes in the plate of Koay.
Response to Arguments
Applicant’s arguments with respect to claims 1 and 14 have been considered but are moot because the arguments do not apply to any of the references being used in the current rejection. The newly presented rejection was necessitated by the amendments to the claims of November 4, 2025.
