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 .
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.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claim 16 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 16 recites the limitation "said base element" in lines 4-5. There is insufficient antecedent basis for this limitation in the claim.
For the purpose of examination, the limitation has been interpreted to read “a base element” as this provides proper antecedence.
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.
Claims 1-5, 7-8, 10-14 and 16 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Matityahu et al. (US 2007/0162016).
Regarding claim 1, Matityahu discloses a polyaxial screw assembly comprising a base element (32) having a hole (102), said hole defining at least one recess (111/112) on a perimeter of said hole (figure 8); a substantially annular-shaped bushing (33), inserted in said hole (figure 9) and tiltable with respect to an axis of said hole (¶59), said bushing comprising at least one outer protrusion (81/82) fitted inside said at least one recess (figures 10-16); a screw (34) inserted in said bushing and passing in said hole, wherein said screw comprises a head (204) and a stem (186), said head being configured to cooperate with said bushing for an angular locking in a spatial direction of said stem with respect to said hole (¶60); wherein said at least one recess has a respective groove (113/114) that is open toward a top side of said base element (figure 8), and wherein said groove has an extent configured for a raising or lowering of said at least one outer protrusion (figures 10-16), allowing a first partial rotation of said bushing prior to said angular locking (figures 10-16).
Regarding claim 2, Matityahu discloses the groove of the at least one recess has a depth extent inside said base element being deeper than a neutral position of said at least one outer protrusion (figures 13-15), said bushing being not tilted with respect to said axis of said hole in said neutral position (figures 10-16).
Regarding claim 3, Matityahu discloses the at least one outer protrusion is partially jutting above said respective groove of said at least one recess in a maximally tilted position of said bushing with respect to said axis of said hole (figures 12).
Regarding claim 4, Matityahu discloses the groove of said at least one recess has a substantially rectilinear development (figure 8, in a top down view), being free from localized enlargements and/or constrictions (figure 8).
Regarding claim 5, Matityahu discloses the at least one recess comprises a pair of diametrically opposite recesses (111, 112) in said hole (figure 8), and wherein said at least one outer protrusion comprises a pair of diametrically opposite outer protrusions (81, 82) in said bushing, said pair of outer protrusions being fitted inside said pair of recesses (figure 13).

Regarding claim 12, Matityahu discloses the top side, where said groove of said at least one recess is open, is a side of said base element (48, ¶37) being opposite to a final mounting position of said stem of said screw (figure 8).
Regarding claim 13, Matityahu discloses the hole defines an at least partially spherical side wall (106, figure 16) thereof, and wherein said bushing comprises a partially spherical outer contour (76, figure 5)configured for a shape coupling with said side wall to allow said angular locking by friction (¶60).
Regarding claim 14, Matityahu discloses the head of said screw comprises a threading (figure 25, ¶54), and wherein said bushing further comprises an inner contour, said inner contour being threaded (74) correspondingly to said head, said head cooperating with said bushing in an at least partially conical coupling to allow said angular locking (¶60).
Regarding claim 16, Matityahu disclose an orthopedic component, such as a prosthesis element or a bone plate (32, figures 1-3), said orthopedic component having at least one hole (102), said at least one hole (102) defining at least one recess (111/112) on a perimeter of said at least one hole, wherein said at least one recess has a respective groove (113/114) being open toward a top side of said base element (48), characterized in that said at least one hole (102) is configured to receive a respective bushing (33) and a respective screw (34) of a polyaxial screw assembly according to claim 1.
Claims 1 and 5-6 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Wiederkehr (US 2017/0265914). Regarding claim 1, Wiederkehr discloses a polyaxial screw assembly comprising a base element (110) having a hole (102), said hole defining at least one recess (113A/133B) on a perimeter of said hole (figure 2); a substantially annular-shaped bushing (140/340), inserted in said hole (figure 2) and tiltable with respect to an axis of said hole (¶52, ¶55), said bushing comprising at least one outer protrusion (358/359) fitted inside said at least one recess (figure 6); a screw (95) inserted in said bushing (figure 1) and passing in said hole, wherein said screw comprises a head (97) and a stem (96), said head being configured to cooperate with said bushing for an angular locking in a spatial direction of said stem with respect to said hole (¶58-59); wherein said at least one recess has a respective groove (120) that is open toward a top side of said base element (figures 1, 6), and wherein said groove has an extent configured for a raising or lowering of said at least one outer protrusion, allowing a first partial rotation of said bushing prior to said angular locking (¶52, ¶55).
Regarding claim 5, Wiederkehr discloses the at least one recess comprises a pair of diametrically opposite recesses (113A, 113B, figure 2) in said hole (102), and wherein said at least one outer protrusion comprises a pair of diametrically opposite outer protrusions (358, 359) in said bushing, said pair of outer protrusions being fitted inside said pair of recesses (figures 2, 6).
Regarding claim 6, Wiederkehr discloses a first protrusion (358) of said pair of outer protrusions is raised and a second protrusion (359) of said pair of outer protrusions is lowered in said first partial rotation of said bushing (201), said pair of outer protrusions being configured to slide inside two grooves of said pair of recesses, respectively (¶52, ¶55).
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 9 is rejected under 35 U.S.C. 103 as being unpatentable over Matityahu (US 2007/0162016) in view of Perrow et al. (US 2009/0062862).
Regarding claim 9, Matityahu disclose the claimed invention including the at least one outer protrusion (81/82) comprises a button-like protrusion (figure 5).
However, Matityahu fails to teach the button-like protrusion has a substantially cylindrical body radially protruding from an annular body of said bushing.
Perrow et al. disclose the use of a bushing (150, figure 16) having at least one outer protrusion (160) which comprises a button-like protrusion (figures 16-18D), having a substantially cylindrical body (figures 16-18D) radially protruding from an annular body of the bushing (150) as it is a known alternative shape for allowing controlled pivoting of the bushing relative to the base element.
Accordingly, it would have been obvious to one of ordinary skill in the art at the time of filing to have constructed the button-like protrusions of Matityahu to be substantially cylindrical as taught by Perrow et al. as it is a known alternative shape for allowing controlled pivoting of the bushing relative to the base element.
Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over Matityahu (US 2007/0162016) in view of Sanders et al. (US 2009/0192549).
Regarding claim 15, Matityahu disclose the claimed invention except for the bushing having a solid body and an open shape (figure 5) instead of a closed perimeter and further comprises a plurality of partial slots extending along an insertion direction of said screw, said plurality of partial slots defining a plurality of radially deformable portions of said bushing, said radially deformable portions of said bushing opening outward with insertion of said screw and providing a friction interaction with said base element. Sanders et al. show that a bushing (14) with a closed perimeter (figures 4C/4D) and further comprises a plurality of partial slots (63’s and/or 65’s) extending along an insertion direction of said screw, said plurality of partial slots defining a plurality of radially deformable portions of said bushing (figures 3A, 7B, ¶49), said radially deformable portions of said bushing opening outward with insertion of said screw and providing a friction interaction with said base element (figures 3A, 4C-4D, 7B) is an equivalent structure known in the art. Therefore, because these two bushing configurations were art-recognized equivalents at the time the invention was made, one of ordinary skill in the art would have found it obvious to substitute the closed perimeter bushing of figures 4C-4D of Sanders et al in for the open/split bushing of Matityahu.
