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 § 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.

With respect to claim 8, Froehlich discloses further comprising at least one rib (fig 3, 30) coupled to and extending radially outwardly from the neck.
With respect to claim 9, Froehlich discloses wherein the expandable member further comprises fenestrations (paragraph 19, made of a woven material such that the space between the weave forms fenestrations).
With respect to claim 10, Froehlich discloses wherein the trunk further defines an orifice (fig 3, 34) between the proximal and distal ends of the trunk and in fluid communication with the bore.
With respect to claim 11, Froehlich discloses wherein the trunk comprises an outer surface and further defines a recess (fig 3, 34) extending inwardly from the outer surface, wherein the recess is sized to receive tissue growth-promoting material.

Ratron discloses an implant (See fig 4 below) with a distal anchor(fig 4, 2) and a proximal anchor (see fig 4 below) extending proximally from the proximal end of the trunk to define a cavity (fig 4, 13), wherein the proximal anchor further defines apertures (fig 4, 15) arranged circumferentially about the longitudinal axis to form deformable features (fig 4, 16) configured to buckle (buckles out into the bone) into engagement with a second bone or section of bone, wherein the apertures are positioned proximal to the proximal end of the trunk (fig 4) to prevent the screw from loosening over time (paragraph 5).
With respect to claim 5, Ratron discloses wherein the proximal anchor comprises a cap (fig 5, 100 pedical screw head), wherein the cap comprises a base, and annular teeth (threads inside the head of 100 for a set screw) disposed at a proximal end of the base and configured to engage complementary teeth of an insertion tool.
With respect to claim 7, Ratron discloses wherein the deformable features of the proximal anchor are integrally formed with the trunk (fig 4 the deformable members are integral).
With respect to claim 12, Ratron discloses wherein the distal anchor, and the proximal anchor are configured to be deployed independently and sequentially (Fig 5 the proximal anchor is deployed first by 100).

With respect to claim 18, Froehlich discloses wherein the stem further defines a counterbore (See fig 4B below) proximal to the bore and configured to receive a delivery cannula for injecting the injectable material into the bore.
With respect to claim 19, Froehlich discloses wherein the expandable member further comprises fenestrations (paragraph 19, made of a woven material such that the space between the weave forms fenestrations).
With respect to claim 20, Froehlich discloses wherein the trunk further defines an orifice (Fig 3, 34) between the proximal and distal ends of the trunk and in fluid communication with the bore.
With respect to claim 17, Froehlich discloses the claimed invention except for a proximal anchor configured to buckle into engagement with a second bone or section of bone, wherein the proximal anchor extends proximally from the proximal end of the trunk.
Ratron discloses an implant (See fig 4 above) with a distal anchor(fig 4, 2) and a proximal anchor (see fig 4 below) configured to buckle (buckles out into the bone) into engagement with a second bone or section of bone, wherein the proximal anchor extends from the proximal end of the trunk (fig 4) to prevent the screw form loosening over time (paragraph 5).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the device of Froehlich to include a proximal anchor configured to buckle into engagement with a second bone or section of bone, wherein the proximal anchor extends proximally from the proximal end of the trunk in view of Ratron in order to prevent the screw form loosening over time.
