Before FRANCISCO C. PRATS, TAWEN CHANG, and RYAN H. FLAX,

FLAX, Administrative Patent Judge.
DECISION ON REQUEST FOR REHEARING
Appellant requested rehearing of the Board’s Decision entered
October 12, 2017, to the extent it entered new grounds of rejection for
claims 1 and 12 under 35 U.S.C. § 102(b) over Kurokawa1.2 Appellant’s
request is GRANTED and the aforementioned rejection is WITHDRAWN.
1 U.S. Patent 4,158,359 (issued June 19, 1979) (“Kurokawa”).
2 A new ground of rejection was also made for claims 28—37 under 35
U.S.C. § 112, second paragraph. Appellant subsequently filed an
amendment to claim 28 (see Amendment dated Dec. 12, 2017), which the
Examiner entered and indicated overcame the indefiniteness rejection (see
Advisory action dated Dec. 28, 2017).
Appeal 2016-008205
Application 12/765,051
Appellant contends “the Board misapprehended or overlooked the
limitations of claims 1 and 12 that require the ridge and reservoir to include
the same absorbent material.” Req. Reh’g 2.
For convenience, we reproduce independent claims 1 and 12 below
(emphasis added):
1. A single piece epicutaneous test chamber comprising:
a reservoir having an inner surface formed of an
absorbent material, and
a ridge for contacting a test surface, the ridge surrounding
the reservoir;
wherein the reservoir and ridge are one continuous piece
formed of the same material.
12. An epicutaneous test chamber comprising:
a reservoir; and
a ridge surrounding the reservoir;
wherein the reservoir and the ridge are entirely integrally
formed of a multilayer material including at least one
absorbent layer and at least one barrier layer.
Regarding claim 1, Appellant argues:
claim 1 does not recite that the reservoir contains an absorbent
material or that an absorbent material is provided on the inner
surface of the reservoir. Instead, claim 1 specifically requires
that the reservoir itself have an inner surface formed of an
absorbent material, i.e., the actual physical structure of the
reservoir incorporates the absorbent material.
Id. at 3. Appellant also argues:
Further, with respect to claim 1, “the reservoir and ridge are one
continuous piece formed of the same material.” Given that the
reservoir has an inner surface made of an absorbent material and
2
Appeal 2016-008205
Application 12/765,051
that the ridge is formed of the same material as the reservoir, the
ridge must also incorporate the absorbent material.
Id. We agree with Appellant’s former statement and not the latter. But, this
agreement is sufficient to conclude the outstanding rejection should be
withdrawn.
Having considered Appellant’s position that claim 1 should be
interpreted such that the claimed “absorbent material” must be an integral
part of the structure defining the claimed reservoir, we conclude that the
plain language of the claim and the disclosure in the Specification support
this position. The Specification generally describes a laminate-type,
multilayer structure that forms the test chamber of the invention. See, e.g.,
Spec. 13—16, 18, 21, 24—29, 31, Figs. 2, 4, 5. More specifically, we note
the Specification states, “the test chamber 104 according to embodiments of
the present invention is a single piece device, unlike prior test chambers
which are an assembly of a separate base piece and a separate wall piece, or
an assembly of a separate chamber piece and a separate filter paper piece,
etc.” Id. 1 56 (emphasis added). Based on this description in the
Specification, in agreement with the Appellant’s position, we conclude that
the claimed absorbent material must be an integral part of the reservoir
structure and cannot be a separable component, e.g., a separate piece of
paper.
However, neither the plain language of the claim nor the
Specification’s disclosure supports Appellant’s position regarding claim 1
that the claimed absorbent material necessarily extends to or over the
claimed ridge. For example, in a hypothetical prior art product, if a
respective absorbent material was provided only as an integrally formed,

Appeal 2016-008205
Application 12/765,051
inner surface of a reservoir, without also extending over a ridge, such an
absorbent material would still form an inner surface of the reservoir and
would also be part of the one continuous piece forming the reservoir and
ridge. Such a configuration would not prevent such a prior art product from
disclosing the limitations of claim 1.
As argued by Appellant, Kurokawa discloses that its porous sheet 9 is
merely “placed in the inside space 5 of the tray 1”; thus, while it is
reasonably identified as an inner surface of the reservoir, the porous sheet 9
is not an integral part of the structure defining the reservoir. Kurokawa
2:62—63. Therefore, we conclude that Kurokawa does not anticipate claim 1
and withdraw the anticipation rejection with respect to this claim.
Regarding claim 12, Appellant argues “claim 12 requires that ‘the
reservoir and the ridge are entirely integrally formed of a multilayer material
including at least one absorbent layer and at least one barrier layer.’” Req.
Reh’g 4. Appellant cites as support the description of Figure 2 in the
Specification, which states that “the multilayer material 132 includes an
absorbent layer 112 and a barrier layer 116.” Id. Appellant argues that, in
contrast, “Kurokawa does not disclose any similar structure. Instead, . . .
Kurokawa at best discloses that the ridge (sealing member 4) and the
reservoir (inner space 5) are made of the same material, but this material is
not a multilayer material and does not include an absorbent layer.” Id.
Appellant’s argument is persuasive. The plain language of claim 12
requires that both the reservoir and ridge consist of (“are entirely integrally
formed of’ (emphasis added)) a multilayer structure, which has at least one
absorbent layer and at least one barrier layer. The claim language, in view
4
Appeal 2016-008205
Application 12/765,051
of the disclosure of the Specification discussed above with respect to claim
1, requires that an absorbent layer is an integral part of the reservoir
structure and, here, also requires that the ridge structure includes this
absorbent layer (i.e., the ridge is entirely formed of the multilayer).
Kurokawa does not disclose that its reservoir and ridge structures include an
integral absorbent layer and, for this reason, we withdraw the rejection as to
claim 12.
DECISION
The anticipation rejection of claims 1 and 12 over Kurokawa is
withdrawn.
GRANTED
