Office Action

§103
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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 04/28/2026 has been entered. Response to Arguments Applicant’s arguments with respect to claim(s) 1-6 and 12-22 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Status The drawing objection have been overcome. Claims 1-6 and 12-22 are examined below. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 1-3, 5-6, 12, 14, 16-19 and 21-22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Vergari (US 2018/0008416 A1) in view of Bergin (US 2007/0118229 A1) and Mattes (US 2018/036898a A1). Regarding claim 1, Vergari teaches a bone implant comprising (100, prosthetic element, fig. 1): a main body (1, central body, fig. 1) comprising a hollow body (2, axial cavity, fig. 1) having a first end (see annotated fig. 1, below) and a second end (see annotated fig. 1, below), the first end and the second end being open in an axial direction (fig. 1) to define a first opening at the first end (see annotated fig. 1, below) and a second opening at the second end (see annotated fig. 1, below), the main body comprising a load-bearing material (¶ [0039]). PNG media_image1.png 487 463 media_image1.png Greyscale Vergari fails to teach a plurality of protrusions. However, Bergin teaches a bone implant that includes a plurality of shaped bodies which protrude from the main body in a radial direction (912, bone engagement members, fig. 16) and comprise the at least one in vivo degradable/in vivo resorbable material (¶ [0091-0094]). Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filling date of the claimed invention to have modified the implant of Vergari to include protrusions as taught by Bergin in order to engage with the bone (¶ [0018], Bergin). Vergari and Bergin fail to teach the plurality of shaped bodies having a predetermined breaking line. However, Mattes teaches a medial product for filling a bone cavity that includes the plurality of shaped bodies comprising at least one shaped body having a predetermined breaking line extending in a longitudinal direction of the at least one shaped body (¶ [0040]), the predetermined breaking line configured to allow the at least one shaped body to be adapted to a specific bone defect (¶ [0040] and ¶ [0154]). Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filling date of the claimed invention to have modified the plurality of shaped bodies of Vergari and Bergin to include a predetermined breaking line as taught by Mattes in order to adapt the sides of the implant to the bone cavity (¶ [0154]). Regarding claim 2, Vergari further teaches the main body has a corner-free cross section (fig. 1). Regarding claim 3, Vergari further teaches the main body is conical and has an at least sectionally tapering inner diameter (¶ [0023]). Regarding claim 5, Vergari further teaches the load-bearing material is an in vivo nondegradable/in vivo nonresorbable material (¶ [0006]). Regarding claim 6, Vergari further teaches the load-bearing material is selected from the group consisting of metals, alloys, ceramics, plastics, and combinations thereof (¶ [0006]). Regarding claim 12, Vergari further teaches the main body comprises a porous and/or microstructured surface (¶ [0006]). Regarding claim 14, Vergari fails to teach the at least one in vivo degradable/in vivo resorbable material is selected from the group consisting of polyhydroxyalkanoates, calcium, phosphates and combinations thereof. However, Bergin further teaches the at least one in vivo degradable/in vivo resorbable material is selected from the group consisting of polyhydroxyalkanoates, calcium, phosphates and combinations thereof (¶ [0013], ¶ [0094]). Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filling date of the claimed invention to have modified the implant of Vergari to include the at least one in vivo degradable/in vivo resorbable material is selected from the group consisting of polyhydroxyalkanoates, calcium, phosphates and combinations thereof as taught by Bergin in order to engage with the bone (¶ [0018], Bergin). Regarding claim 16, Vergari further teaches the main body has a circular, oval or elliptical cross section (fig. 1). Regarding claim 17, Vergari further teaches the load-bearing material is selected from the group consisting of titanium, tantalum, titanium alloys, polyetherketones, polyetheretherketone, polyetherketoneketone, polyetheretheretherketone, polyetheretherketoneketone, polyetherketoneetherketoneketone, polyolefins and combinations thereof (¶ [0026]). Regarding claim 18, Vergari further teaches the main body and/or the plurality of shaped bodies have an open-pored surface (¶ [0006]). Regarding claim 19, Vergari fails to teach the at least one in vivo degradable/in vivo resorbable material is selected from the group consisting of polylactide, polyglycolide, polycaprolactone, (β-tricalcium phosphate, hydroxyapatite and combinations thereof. However, Bergin further teaches the at least one in vivo degradable/in vivo resorbable material is selected from the group consisting of polylactide, polyglycolide, polycaprolactone, (β-tricalcium phosphate, hydroxyapatite and combinations thereof (¶ [0013], ¶ [0094]). Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filling date of the claimed invention to have modified the implant of Vergari to include the at least one in vivo degradable/in vivo resorbable material is selected from the group consisting of polylactide, polyglycolide, polycaprolactone, (β-tricalcium phosphate, hydroxyapatite and combinations thereof as taught by Bergin in order to engage with the bone (¶ [0018], Bergin). Regarding claim 21, Vergari further teaches the main body comprising a wall (18, outer surface, fig. 18) defining a first side (see annotated fig. 1, below), a second side opposite the first side (see annotated fig. 1, below), a third side (see annotated fig. 1, below) and a fourth side opposite the third side (see annotated fig. 1, below), the first side defining a first cutout that (13, notch, fig. 1) is open and contiguous with the first opening at the first end (fig. 1), the second side defining a second cutout (14, notch, fig. 1) that is also open and contiguous with the first opening at the first end (fig. 1) wherein the first cutout is U- shaped (fig. 1, ¶ [0027]) and the second cutout is U-shaped (fig. 1, ¶ [0027]). PNG media_image2.png 431 505 media_image2.png Greyscale Vergari fails to teach a first group of shaped bodies and a second group of shaped bodies. However, Bergin further teaches the plurality of shaped bodies comprising a first group of shaped bodies that protrude radially from the third side (912, bone engagement members, fig. 16) and a second group of shaped bodies that protrude radially from the fourth side (912, bone engagement members, fig. 16). Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filling date of the claimed invention to have modified the implant of Vergari to include protrusions as taught by Bergin in order to engage with the bone (¶ [0018], Bergin). Regarding claim 22, Vergari further teaches the first cutout is diametrically opposite the second cutout (fig. 1, ¶ [0027]). Claim(s) 4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Vergari in view of Bergin and Mattes as applied to claim 1 above, and further in view of Polguj (Morphological study of linea aspera variations). Regarding claim 4, Vergari in view of Bergin and Mattes fails to teach the main body has a wall thickness of 1 mm to 30 mm. However, Polguj teaches the largest bone in the body, the femur, has an average diameter of 32.5 mm ± 2.3 mm in females and 33.1 mm ± 1.9 mm in males (Table 1). Therefore, it would have been obvious to try for someone of ordinary skill in the art before the effective filling date of the claimed invention to modify the bone implant of Vergari and Bergin and Mattes to include the main body has a wall thickness of 1 mm to 30 mm as taught by Polguj in order for the implant to work with the known anatomies of patients. Claim(s) 13, 15 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Vergari in view of Bergin and Mattes as applied to claim 1 above, and further in view of Biris (WO 2016/057684 A1). Regarding claim 13, Vergari in view of Bergin and Mattes fails to teach the in vivo degradable/in vivo resorbable material comprises two materials with different in vivo degradation rates/in vivo resorption rates. However, Biris teaches a biocompatible structures for regeneration of tissue that includes the at least one in vivo degradable/in vivo resorbable material comprises at least two in vivo degradable/in vivo resorbable materials (100, first base structure, 200, second base structure, fig. 1A) which differ from one another with regard to their in vivo degradation rate/in vivo resorption rate (page 37, lines 16-19). Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filling date of the claimed invention to have modified the bone implant of Vergari and Bergin and Mattes to include the in vivo degradable/in vivo resorbable material comprises two materials with different in vivo degradation rates/in vivo resorption rates as taught by Biris in order to accommodate regeneration of different tissues (abstract, Biris). Regarding claim 15, Vergari in view of Bergin and Mattes fails to teach producing the bone implant by an additive manufacturing process. However, Biris further teaches producing the bone implant by an additive manufacturing process (page 55 line 37 – page 56 line 5). Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filling date of the claimed invention to have modified the bone implant of Vergari and Bergin and Mattes to include producing the bone implant by an additive manufacturing process as taught by Biris in order to make a three-dimensional solid object of virtually any shape (page 55, line 27-28, Biris). Regarding claim 20, Vergari in view of Bergin and Mattes fails to teach the at least two in vivo degradable/in vivo resorbable materials are selected from the group consisting of polyhydroxyalkanoates, calcium phosphates and combinations thereof. However, Biris further teaches the at least two in vivo degradable/in vivo resorbable materials are selected from the group consisting of polyhydroxyalkanoates, calcium phosphates and combinations thereof (page 5 line 28- page 6 line 13). Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filling date of the claimed invention to have modified the bone implant of Vergari and Bergin and Mattes to include the at least two in vivo degradable/in vivo resorbable materials are selected from the group consisting of polyhydroxyalkanoates, calcium phosphates and combinations thereof as taught by Biris in order to accommodate regeneration of different tissues (abstract, Biris).
