We AFFIRM-IN-PART.1
THE INVENTION
Appellant’s claimed invention relates to an embryo delivery catheter
to deliver an embryo to a uterus of a subject. Claims 1, 14, 32, and 37 are
independent. Claim 1, reproduced below, is representative of the subject
matter on appeal.
1. An embryo delivery catheter to deliver an embryo to a
uterus of a subject comprising:
a tubular shaft comprising a tubular body with a proximal
portion and a distal portion, the tubular shaft having a length to
be inserted through a channel of a hysteroscope, the tubular
body defining a lumen from the proximal portion to the distal
portion, the distal portion having an exterior dimension suitable
for insertion into the uterus of the subject as a procedural
instrument in an embryo delivery procedure, the distal portion
having a beveled opening, such that a length of the shaft to a
first point at the beveled opening is a first length and a length of
the shaft to a second point at the beveled opening is a second
length longer than the first length, a portion of the tubular body
of the shaft extending a length distally from the second point
and defining a tip, wherein the tip comprises a material that has
sufficient rigidity to penetrate an endometrial lining of the
subject and sufficient flexibility to resist penetration of a uterine
muscle of the subject, and wherein the tip has a shape that is
suitable for insertion into the endometrial lining of the subject
as a microsurgical instrument to form a pocket in the
endometrial lining that is to receive the embryo through the
beveled opening.

THE EVIDENCE
The Examiner relies upon the following evidence:
Owings US 2,904,045 Sep. 15, 1959
Saito US 5,575,780 Nov. 19, 1996
Fisher US 6,709,408 B2 Mar. 23, 2004
THE REJECTIONS
Appellant seeks review of the following rejections:
1. Claim 12 is rejected under 35 U.S.C. § 101 as being directed to
patent-ineligible subject matter.
2. Claims 1, 3-5, 7, 10-12, 14-27, and 29-46 are rejected under
35 U.S.C. § 103(a) as being unpatentable over Fisher and Saito.
3. Claim 2 is rejected under 35 U.S.C. § 103(a) as being unpatentable
over Fisher, Saito, and Owings.2
The Final Office Action from which this appeal is taken includes a
rejection of claim 28 under 35 U.S.C. § 112, first paragraph, for failing to
comply with the written description requirement. Final Office Action, p. 3;
see also Ans. 5. Appellant lists claim 28 as a claim on appeal but does not
include the rejection of claim 28 under 35 U.S.C. § 112, first paragraph, in
the listing of the Grounds of Rejection to be Reviewed on Appeal and does
not present arguments against this ground of rejection. App. Br. 4, 10. As

2 Appellant lists claim 2 as a claim on appeal but does not include the
separate ground of rejection of claim 2 under 35 U.S.C. § 103(a) in the
listing of the Grounds of Rejection to be Reviewed on Appeal. App. Br. 4,
10. We understand Appellant to be seeking review of the rejection of claim
2 based on the arguments presented against the base combination of Fisher
and Saito as they apply to independent claim 1, from which claim 2 depends.

such, we summarily sustain the rejection of claim 28 under 35 U.S.C. § 112,
first paragraph.
ISSUES
The issues presented by this appeal are:
Is a claim directed to a catheter comprising an embryo in the distal
portion directed to patent-ineligible subject matter?
Did the Examiner articulate adequate reasoning based on rational
underpinnings to explain why one of ordinary skill in the art would have
been led, in light of Saito, to modify the beveled opening on Fisher’s
aspiration biopsy needle to include a tip extended therefrom?
ANALYSIS
Rejection under 35 U.S.C. § 101
The Examiner rejected claim 12 because it positively recites non-
statutory subject matter, i.e., a human embryo. Ans. 5. Appellant argues
that claim 12 does not claim an embryo, but rather claims a catheter having
an embryo in the distal portion. App. Br. 20. Appellant further argues that
“as claimed, the embryo in the catheter is a non-naturally occurring
combination (e.g., outside the human body), which does not occur in nature
(i.e., extracted embryos within catheters do not occur in nature), but rather is
the product of human ingenuity.” App. Br. 20-21.
We disagree with Appellant’s contention that claim 12 does not
positively recite an embryo. Claim 12 is directed to the combination of a
catheter and an embryo, and thus positively recites an embryo. If Appellant
had intended not to encompass an embryo, the claims could have recited that

Application 11/388,467

5
“the distal portion of the catheter is adapted to receive/hold an embryo.”
Appellant chose, however, to positively claim an embryo within the distal
portion.
Appellant does not challenge the Examiner’s determination that a
human embryo is non-statutory subject matter. Rather, Appellant argues
that because the non-statutory subject matter is claimed in combination with
statutory subject matter, the claims are directed to statutory subject matter.
The fact that the claims cover patent-eligible subject matter, i.e., a catheter
or device, in combination with patent-ineligible subject matter, a human
embryo, does not render the claims patent eligible. To allow one to sidestep
35 U.S.C. § 101 by simply pairing in combination patent-ineligible subject
matter with patent-eligible subject matter would impermissibly exalt claim
strategy (form) over claimed subject matter (substance).3 As such, we affirm
the rejection of claim 12 under 35 U.S.C. § 101 as being directed to patent-
ineligible subject matter.
Rejections under 35 U.S.C. § 103(a)
The Examiner determined that Fisher discloses a hollow needle
having a beveled opening, but does not disclose that the second point of the
needle shaft is distally extended defining a tip. Ans. 6. The Examiner

3 We note that section 33(a) of the Leahy-Smith America Invents Act (AIA)
creates a statutory expression of the Office’s longstanding position that
human organisms are not patent-eligible subject matter. AIA, Public Law
112-29, sec. 33(a), 125 Stat. 284 (Sept. 16, 2012) (“Notwithstanding any
other provision of law, no patent may issue on a claim directed to or
encompassing a human organism.”).

determined that Saito discloses a medical needle including a beveled distal
portion where a portion of the shaft extends distally from the second point
defining a tip. Ans. 6-7. The Examiner concluded that “it would have been
obvious to one skilled in the art to modify the Fisher’s beveled opening at
the distal end to include a tip extended from the second point, taught by
Saito, for purposes of maintaining materials thereon.” Ans. 7.
Appellant argues that the Examiner failed to articulate adequate
reasoning based on rational underpinning to modify Fisher’s aspiration
biopsy needle to include the tip of Saito, because such a modification would
place the scraped cellular material farther from the entry of the lumen where
the material would be subjected to reduced vacuum levels, and that
maintaining materials on the tip is contrary to the objective of Fisher of
sucking or drawing the materials into the lumen of the needle. App. Br. 15.
Fisher discloses a hollow aspiration biopsy needle having a first sharp
edge comprised of a beveled distal end of the needle. Fisher, col. 3, ll. 48-
53. Fisher also discloses a second sharp edge formed on the opening of a
slot disposed transversely relative to the longitudinal axis of the needle.
Fisher, col. 3, ll. 55-63. These first and second sharp edges enable Fisher’s
needle to scrape cellular material during both proximal-to-distal and distal-
to-proximal travel of the needle. Fisher, col. 3, ll. 48-63. Fisher discloses
that the structure also includes conventional means for applying a vacuum to
a proximal end of the needle so that cellular material removed by the first
and second sharp edges is pulled into the lumen. Fisher, col. 3, l. 63 – col. 4,

l. 2. Fisher does not discuss a need to maintain materials on a tip of the
aspiration biopsy needle.
Saito discloses “a medical hollow needle, such as a needle for
hypodermic injection, dialysis, intravenous drip and blood collection, and a
cannular needle. . . .” Saito, col. 1, ll. 7-9. Saito discloses that the sharp
edge of the needle is made “extremely thin” so that “a patient or the like
hardly gets hurt in blood vessel at the injection part at the time of execution
of injection . . . and he can hardly feel the pain at the injection part.” Saito,
col. 2, ll. 16-24. Saito does not disclose forming a thinned portion on the
sharp edge of the needle so as to maintain materials on a tip of the needle.
The Examiner failed to adequately explain why one of ordinary skill
in the art would have found it desirable to modify the needle of Fisher to
render it capable of maintaining materials on a tip of the needle, and neither
reference describes maintaining materials on the tip of the needle during use.
As such, the Examiner’s articulated reasoning is inadequate to explain why
one of ordinary skill in the art would have been led to make the proposed
modification to result in the claimed invention. “[R]ejections on
obviousness grounds cannot be sustained by merely conclusory statements;
instead, there must be some articulated reasoning with some rational
underpinning to support the legal conclusion of obviousness.” In re Kahn,
441 F.3d 977, 988 (Fed. Cir. 2006) (cited with approval in KSR Int’l Co. v.
Teleflex Inc., 550 U.S. 398, 418 (2007)). Accordingly, we reverse the
rejection of claims 1, 3-5, 7, 10-12, 14-27, and 29-46 under
35 U.S.C. § 103(a) based on Fisher and Saito.
Appeal 2012-001507
Application 11/388,467

8
The Examiner’s rejection of dependent claim 2 under
35 U.S.C. § 103(a) as being unpatentable over Fisher, Saito, and Owings
suffers from the same deficiency in that the rejection is based on inadequate
reasoning to modify Fisher with the teaching of Saito. Ans. 9.
Accordingly, we also reverse the rejection of claim 2 under
35 U.S.C. § 103(a) as being unpatentable over Fisher, Saito, and Owings.
CONCLUSIONS
The claim directed to a catheter comprising an embryo in the distal
portion is directed to patent-ineligible subject matter.
The Examiner failed to articulate adequate reasoning based on rational
underpinnings to explain why one of ordinary skill in the art would have
been led, in light of Saito, to modify the beveled opening on Fisher’s
aspiration biopsy needle to include a tip extended therefrom.
DECISION
We AFFIRM the decision of the Examiner to reject claim 12 under
35 U.S.C. § 101 and claim 28 under 35 U.S.C. § 112, first paragraph. We
REVERSE the decision of the Examiner to reject claims 1-5, 7, 10-12, 14-
27, and 29-46 under 35 U.S.C. § 103(a).
No time period for taking any subsequent action in connection with
this appeal may be extended under 37 C.F.R. § 1.136(a). See 37 C.F.R.
§ 1.136(a)(1)(iv).
