DECISION ON APPEAL
I. STATEMENT OF CASE
Wimco, LLC (hereinafter “Appellant”), the real party in interest1 of Patent
7,488,414 B2 (hereinafter the “’414 patent”), appeals under 35 U.S.C. §§ 134(b)
and 306 from the Examiner’s decision to reject claims 1-7 and 9-14 (Final Office
Action, mailed June 14, 2012, pages 3-9). We have jurisdiction under 35 U.S.C.
§§ 134(b) and 306.

1 See Appellant’s Appeal Brief 2, filed November 13, 2012 (hereinafter “App.
Br.”).

We AFFIRM.
This reexamination proceeding arose from a third-party request for ex parte
reexamination filed by Appellant (Request for Ex Parte Reexamination, filed May
19, 2011). Claims 8 and 15-19 were not subject to the reexamination request. See
Ans. 3, n. 2. Original claims 1-7 and 9-14 of the ’414 patent have not been
amended during this reexamination proceeding. Claims 1-19 were confirmed in a
prior Ex Parte Reexamination Certificate issued January 11, 2011 (Reexamination
Control 90/009,716).
The ’414 patent relates to an erosion control basin and drain used during
construction of curbs and gutters around storm sewer drain frames to prevent
debris and sediment from entering a storm sewer (’414 patent, col. 1, ll. 17-42).
The ’414 patent is related to U.S. Patent 7,396,471, the subject of Reexamination
Control 90/011,699, also currently on appeal. The ’414 patent also is related to
U.S. Patent 7,052,207, the subject of Reexamination Control 90/009,717, for which
the Board issued a Decision on Appeal on September 26, 2011.
Representative claim 1 on appeal reads as follows (with additional
indentation for clarity):
1. An apparatus for positioning within an inlet to a storm
sewer having a frame supporting a grate, and a curb box, the apparatus
comprising:
a structure engaging the frame such that the structure is
suspended beneath an area covered by the grate, the structure
comprising a filtered outlet; and
an imperforate deflecting wall attached to the structure and
substantially across a length of the frame and extending upwardly into
the curb box and behind the grate when positioned on the frame and
Appeal 2013-008339

wherein storm water enters the structure through the grate and
the water flows though the filtered outlet remove sediment and debris
from the water entering the storm sewer and
wherein the deflecting wall extends into the curb box to deflect
water into the structure while allowing water to overflow the
deflecting wall in the event that the filter plugs or a street floods due
to excessive amounts of water flowing into the sewer.
(Claims App’x, App. Br. 15.)
II. REJECTIONS
The Examiner maintains the following rejections on appeal;
1. Claim 1 under 35 U.S.C. § 102(e) as anticipated by Gauldin;2
2. Claims 1-7 and 9-14 under 35 U.S.C. § 102(e) as anticipated by Morris;3
3. Claims 1-7 and 9-14 under 35 U.S.C. § 103(a) as unpatentable over
Morris, Lewis4 and Isaacson;5
4. Claims 1-7 and 9-14 under 35 U.S.C. § 103(a) as unpatentable over
Paoluccio6 and Gauldin;
5. Claims 1-7 and 9-14 under 35 U.S.C. § 103(a) as unpatentable over
Paoluccio, Morris, and Lewis; and
6. Claims 1-7 and 9-14 under 35 U.S.C. § 103(a) as unpatentable over
Paoluccio, Morris, Lewis, and Isaacson.

III. ISSUES
Appellant contends that it has submitted sufficient evidence to demonstrate
that the claimed invention antedates each of the Gauldin and Morris disclosures,
thus removing them as appropriate prior art references. See App. Br. 8-13. In
support thereof, Appellant relies on three declarations of Brian Wimberger,
inventor of the ’414 patent.7
The Examiner finds that the Declaration evidence is insufficient to
demonstrate that the claimed subject matter antedated the Gauldin and Morris
disclosures because the Declaration evidence does not demonstrate the
“relationship between the claimed ‘deflecting wall’ and ‘curb box’ features,”
namely a deflecting wall “extending upwardly into the curb box” as recited in the
independent claims. Ans. 12-13.
Accordingly, the issues on appeal are:
1. Do the claims require a specific relationship between the deflecting wall
and the curb box by the language in the claims reciting a deflecting wall
“extending upwardly into the curb box”? and
2. If so, does the evidence show that the inventor had reduced to practice
this recited relationship prior to the disclosure dates of Gauldin and
Morris?

7 The first Declaration under 37 C.F.R. § 1.131 of Brian Wimberger, dated
November 15, 2011 (hereinafter “First Declaration” or “First Decl.”). The Second
Declaration under 37 C.F.R. § 1.131 of Brian Wimberger, dated May 8, 2012
(hereinafter “Second Declaration” or “Second Decl.”). The Third Declaration
under 37 C.F.R. § 1.131 of Brian Wimberger, dated August 13, 2012 (hereinafter
“Third Declaration” or “Third Decl.”).

read in light of the specification as it would be interpreted by one of ordinary skill
in the art.” In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1364 (Fed. Cir. 2004)
(quoting In re Bond, 910 F.2d 831, 833 (Fed. Cir. 1990)).
The independent claims recite that it is the deflecting wall that “extends”
into the curb box. However, the ’414 patent does not use the word “extends” with
respect to the deflecting wall 46. The common meaning of “extend” is “to stretch
forth,” such as to extend one’s arms.8 Thus, the claims are reasonably interpreted
to require that the deflecting wall extends or stretches forth from where it is
attached to the structure, into the curb box. Appellant’s argument that the bottom
of the deflecting wall is within the curb box is not consistent with the language of
the claims. That is, in order for such a configuration to meet the claim limitation,
the point from which the deflecting wall would “extend” into the curb box, would
be a point on the deflecting wall above the structure, and extending downward
from space into the curb box where it is then connected to the structure. This is
inconsistent with the language of the claims, which recite that the structure has a
deflecting wall that extends into the curb box, rather than a deflecting wall that
extends into the curb box and attaches to the structure. Thus, the deflecting wall
must extend into the curb box from the perspective of the structure.
The independent claims further recite expressly that the deflecting wall
“extend[s] upwardly into the curb box”, which further supports the interpretation
of the claims discussed supra.
Accordingly, we agree with the Examiner’s interpretation that the claims
require the deflecting wall to extend upwardly from the structure into the curb box.

The deflecting wall does not appear to be connected or attached in any other
manner so as to extend upwardly in any other manner.
The Wimberger Declarations
To resolve the question of whether the Wimberger Declarations presents
enough evidence to overcome the rejections, the main question we must answer is
whether the showing is sufficient to establish a reduction to practice of the
invention claimed. We emphasize the words “invention claimed” because
Appellant must establish that each and every limitation of the claim was present in
its evidence showing reduction to practice. See In re Tanczyn, 347 F.2d 830, 833
(CCPA 1965) (Reduction to practice of a nitrogen-containing stainless steel did not
overcome a rejection because the appellant did not establish possession the claimed
stainless steel that contained molybdenum as well as nitrogen). The burden for
establishing reduction to practice of the claimed invention lies with the Appellant.
In re NTP, Inc., 654 F.3d 1279, 1291 (Fed. Cir. 2011) (“A party seeking to
antedate a reference based on reduction to practice must present evidence of the
actual reduction to practice of the invention prior to the effective date of the
reference. An inventor cannot rely on uncorroborated testimony to establish a
prior invention date. It has long been the case that an inventor’s allegations of
earlier invention alone are insufficient—an alleged date of invention must be
corroborated.”) (internal citation omitted).
The Wimberger Declarations rely on photographs A1 to A4 attached thereto
as evidence of a reduction to practice of the claimed invention. The Examiner
found that the photographs are insufficient evidence that the inventor reduced to
practice the claimed invention, particularly an apparatus having a deflecting wall
“extending upwardly into a curb box.” The Examiner states that “the photographs

Reexamination Control 90/011,700
Patent 7,488,414 B2

9
submitted with the Declaration, in particular Exhibits A2 and A3, depict the
deflecting wall 18 as being outside of the curb box 5.” Ans. 13. The Examiner
also found that the photographs are insufficient evidence to corroborate
Mr. Wimberger’s testimony that the presence of a gap between the deflecting wall
and the basin “allows the bottom portion of the imperforate deflecting wall to be
positioned with the curb box.” Ans. 13 (citing Third Decl. ¶ 6).
We agree with the Examiner that photographs A1-A4 do not provide
sufficient evidence to corroborate Mr. Wimberger’s testimony that (1) “the bottom
portion of the imperforate wall is within the curb box” or (2) that the “inset edges”
of the back flange “allows the bottom portion of the imperforate deflecting wall to
be positioned with the curb box.” Third Decl. ¶¶ 6-7.
Photographs A2 and A3 are not sufficiently clear to show whether or not the
“bottom portion” of deflecting wall 18 is “within the curb box.” The images are
not taken from an angle and/or have not been provided with sufficient resolution to
reliably corroborate the statements made by Mr. Wimberger.
Even if there was sufficient corroborating evidence to show that a bottom
portion of the deflecting wall is within the curb box, we agree with the Examiner
that the photographs A2 and A3 clearly show the deflecting wall extending
upwardly from the flange out of the curb box and not “into the curb box” as
required by the claims and interpreted above. Appellant has presented no
argument addressing why positioning of the bottom portion of the deflecting wall
in the curb box would constitute the deflecting wall “extending upwardly into the
curb box.”
Appellant further contends that “[t]he length [horizontal width] of the
deflecting wall is merely a design choice to fit a particular sewer inlet” and that

“modifying a length of an imperforate deflecting wall to fit within a curb box . . .
was obvious to one of ordinary skill in the art.” App. Br. 10 and Reply Brief 6,
filed March 25, 2013. To antedate these prior art references, Appellant must
establish possession of either the whole claim or something falling within the
claim. Tanczyn, 347 F.2d at 833. In the case of an obviousness rejection,
Appellant need only show possession of as much of the claimed invention as is
shown in the reference that is to be antedated. Here, the Examiner found that both
Gauldin and Morris disclose a deflecting wall that fits within a curb box. Ans. 5-7.
Thus, Appellant’s position that modifying a deflecting wall such that it extends
into a curb box would have been a mere design choice or obvious to the skilled
artisan is not persuasive. Further, Appellant has provided no meaningful evidence
that the inventor was aware of such a modification or had considered modifying
the deflecting wall to fit the size of the curb box.
Accordingly, we agree with the Examiner that the evidence is not sufficient
to antedate the Gauldin and Morris references.
Since Appellant presents no arguments against the substance of the
rejections based on Gauldin and Morris, we affirm all the rejections maintained by
the Examiner.
V. CONCLUSION
On the record before us, we affirm the rejections maintained by the
Examiner.
