SCHOPPER, Administrative Patent Judge.
DECISION ON APPEAL
This is an appeal under 35 U.S.C. § 134(a) from the Examiner's Final
Rejection of claims 1, 15, and 17, which constitute all the claims pending in
this application. Claims 2-14, 16, and 18-23 have been cancelled. We have
jurisdiction under 35 U.S.C. § 6(b ). We AFFIRM-IN-PART.

2017), the Reply Brief ("Reply Br.," filed Mar. 16, 2018), the Examiner's
Answer ("Ans.," mailed Jan. 16, 2018), and the Final Office Action ("Final
Act.," mailed Apr. 11, 2017).

Appeal2018-004301
Application 12/140,412
BACKGROUND
According to Appellants, the Specification provides embodiments of
"an adjustable implant assembly that provides for controlled adjustment of a
spinal connection element, such as a spinal rod, received in a body of the
implant assembly relative to the body of the bone screw." Spec. ,r 6.
CLAIMS
Claims 1 and 15 are the independent claims on appeal. Claim 1 is
illustrative of the appealed claims, and recites:
1. An implant assembly comprising:
a bone anchor having a distal shaft extending along a
longitudinal axis configured to engage bone;
a proximal head portion connected to the bone anchor
wherein the proximal head portion is a closed-type screw head,
wherein the longitudinal axis of the bone anchor aligns with a
longitudinal axis extending through the proximal head portion,
and the proximal head portion is integral with the bone anchor
and includes a central bore;
a cradle within the proximal head portion for receiving a
spinal fixation element, wherein the cradle can move relative to
the proximal head portion allowing the spinal fixation element to
pivot relative to the head portion, wherein the cradle comprises
a spherical body with a central bore for receiving the spinal
fixation element, the body being formed by an upper element that
is a half sphere in shape and a lower element that is a half sphere
in shape, wherein the upper element and the lower element have
interlocking surface configurations to assist in mating the upper
element and lower element; and
a locking mechanism for locking a position of the cradle
in the central bore of the proximal head portion and for, in
conjunction with side walls of the central bore, mating the upper
element and the lower element of the cradle.

REJECTIONS
1. The Examiner rejects claims 15 and 1 7 under 3 5 U.S. C. § 112, second
paragraph, as indefinite.
2. The Examiner rejects claim 1 under 35 U.S.C. § I03(a) as unpatentable
over Lowery3 in view of Ely. 4
3. The Examiner rejects claims 15 and 17 under 35 U.S.C. § I03(a) as
unpatentable over Lowery in view of Ely and Kwak. 5
DISCUSSION
Indefiniteness
The Examiner finds claim 15 "indefinite for referring to 'the locking
element' with improper antecedent basis." Final Act. 2. We agree and note
that Appellants do not appear to respond to this rejection. Accordingly, we
sustain the rejection of claim 15 as indefinite, and we also sustain the
rejection of claim 17 as indefinite based on its dependence from claim 15.
Obviousness
Claim 1
Claim 1 requires the implant assembly to include a "cradle" that
comprises a "body" which is "formed by an upper element that is a half
sphere in shape and a lower element that is a half sphere in shape." Appeal
Br. 11. Claim 1 also requires these half-spherical elements to have
"interlocking surface configurations." Id.

Appeal2018-004301
Application 12/140,412
With respect to claim 1, we are persuaded by Appellants' argument
that the Examiner has not established that the art of record shows or suggests
the cradle required by claim 1. See Appeal Br. 5-7.
In the rejection, the Examiner finds that Lowery teaches a cradle with
a body that is formed of upper and lower elements that are half-spheres.
Final Act. 3--4. The Examiner acknowledges that Lowery "is silent with
regards to the lower and upper elements including interlocking surface
configurations to assist in mating the lower element and the upper element."
Id. at 4. However, the Examiner finds that Ely teaches "a cradle/bearing"
that may be a complete bearing, a split bearing, or a slotted bearing, which
"are known equivalents." Id. at 5 ( citing Ely ,r 69). The Examiner
concludes that it would have been obvious to modify Lowery "to have the
cradle comprised of separate elements that operably connect via interlocking
surface configurations (e.g.[,] a split bearing) ... based on the recognized
equivalence in the art." Id. The Examiner also concludes that because
Appellants have not disclosed that this feature of the claim "solves any
particular problem or is done for a special reason," the modification would
be an obvious design choice and "would perform equally well with the
cradle disclosed by Lowery." Id.
We agree with Appellants that the rejection includes reversible error
at least because the Examiner has not established that the combination of art
would result in a cradle including upper and lower elements that have
interlocking surface configurations, as required by the claim. In the
rejection, the Examiner appears to indicate that Ely is relied upon to teach
interlocking surface configurations, but the Examiner has not pointed to any
portion of Ely that shows such interlocking surfaces. See, e.g., Ely Fig. 4C;

Appeal2018-004301
Application 12/140,412
,r 69. In the Answer, the Examiner appears to rely on Lowery as disclosing
"interlocking features 3 80," and that "the [ c ]ombination suggested actually
results in the cradle of Lowery (Figure 1 a item 3 80) to be split along its
swirling slit so that it is actually two, mating ( operably coupled), semi-
spherical halves that interlock along the swirling slit." Ans. 11-12
( emphasis omitted). However, without further explanation by the
Examiner,, it cannot be concluded that Ely's mere disclosure of complete
bearings or bearings including a split or slot establishes sufficiently that it
would have been "obvious to simply snip through those slots 380 to create a
complete split" in Lowery's cradle. Id. at 12. Further, it is not clear how
snipping through the slots in Lowery would either result in two half
spherical members or members with interlocking surface configurations; i.e.
we are uncertain where the Examiner proposes that one of ordinary skill
would have found it "obvious to snip" Lowery's cradle to arrive at the
claimed configuration.
Based on the foregoing, we are persuaded of error in the rejection of
claim 1. Accordingly, we do not sustain the rejection of claim 1 as obvious.
Claims 15 and 17
Independent claim 15 includes similar limitations to those discussed
above with respect to claim 1. See Appeal Br. 11-12. In particular,
claim 15 claim requires a spherical body that comprises upper and lower half
spherical elements with interlocking surface configurations, similar to the
cradle ofclaim 1. Id. The rejection with respect to these features of claim 15
is substantially similar to the rejection of claim 1. See Final Act. 5-7. The
Examiner additionally relies on Kwak in this rejection. Id. at 8-9. However
the Examiner only relies on Kwak insofar as "Kwak teaches a polyaxial
5
Appeal2018-004301
Application 12/140,412
bone screw that includes a cradle element ... that locks the position of the
screw in place ... with direct contact with the upper element of the cradle."
Id. at 8. Thus, the Examiner does not rely on Kwak in a manner that cures
the deficiency in the combination of Lowery and Ely as discussed above.
Accordingly, for the reasons discussed above, we also do not sustain the
rejection of independent claim 15 or dependent claim 17.
CONCLUSION
We AFFIRM the rejection of claims 15 and 17 under 35 U.S.C. § 112,
second paragraph. We REVERSE the rejections of claims 1, 15, and 17
under 35 U.S.C. § 103(a).
