DECISION ON APPEAL
Appellants appeal under 35 U.S.C. § 134(a) from the Examiner's
rejection of claims 1, 3-8, 10-16, and 18-20, which are all the claims
pending in the application. We have jurisdiction under 35 U.S.C. § 6(b ).
We reverse.

STATEMENT OF THE CASE
Introduction
According to the Specification, the present invention relates generally
to communication systems, and more particularly to a codebook generation
system and associated methods. See Spec. 1. Claim 1 is exemplary:
1. An apparatus, comprising:
a memory to store a codebook; and
a processor circuit arranged to:
select a precoding matrix based on an index received
from a remote device over a communication channel of a
closed-loop multiple-input and multiple-output (MIMO)
orthogonal frequency-division multiple access (OFDMA)
system, the precoding matrix dynamically constructed by
selection of one or more vectors from the stored codebook and
an application of a transform to the one or more vectors; and
precode information with the precoding matrix for
transmission over multiple transmitter antennae.
References and Rejections
Claims 1, 3-8, 10-16, and 18-20 stand rejected underpre-AIA 35
U.S.C. § I03(a) as being unpatentable over Applicants' Admitted Prior Art
(Spec. 1: 15-2: 12) ("AAPA") and Tong (US 2008/0108310 Al, published
May 8, 2008) (using Figure 7 of Giaimo (US 2004/0090924 Al, published
May 13, 2004) to show the typical structure of an 802.11 system).
Alternatively, claims 1, 3-8, 10-16, and 18-20 stand rejected under
pre-AIA 35 U.S.C. § I03(a) as being unpatentable over AAPA and "Unified
MIMO Pre-Coding based on Givens Rotation," IEEE C802.16e-04/5I6, 1-
11 (November 4, 2004) ("Ansari") (using Giaimo's Figure 7 to show the
typical structure of an 802.11 system).

Alternatively, claims 1, 3-8, 10-16, and 18-20 stand rejected under
pre-AIA 35 U.S.C. § I03(a) as being unpatentable over AAPA and "Channel
Feedback Quantization Methods for MISO and MIMO Systems," Vol. 2,

Communications PIMRC 2004, 805-809 (September 5-8, 2004) ("Roh")
(using Giaimo's Figure 7 to show the typical structure of an 802.11 system).
ANALYSIS
We have reviewed the Examiner's rejection in light of Appellants'
contentions and the evidence of record. We concur with Appellants'
contention that the Examiner erred in determining the cited portions of
AAPA and Tong (or alternatively, AAPA and Ansari; or AAPA and Roh)2
collectively teach "the precoding matrix dynamically constructed by
selection of one or more vectors from the stored codebook and an
application of a transform to the one or more vectors," as recited in
independent claim 1 (emphasis added). See Br. 12-14.
The Examiner cites AAPA's page 1, line 15 through page 2, line 12
for teaching the italicized claim limitation. See Final Act. 4--5; Ans. 25-26.
However, the Examiner does not specifically map the "dynamically"
constructed precoding matrix. Nor does the Examiner explain why AAPA
describes "dynamically" constructing the precoding matrix.
Further, we have reviewed the cited AAPA's portions, and they do not
describe the "precoding matrix dynamically constructed," as required by
claim 1. To the contrary, the cited AAPA's excerpts describe storing-not
2 In alternative rejections, the Examiner cites Ansari (or Roh) instead of
Tong. Our analysis and conclusion remain the same regardless of whether
the Examiner cites Tong, Ansari, or Roh as the secondary reference.

"dynamically" constructing-the precoding matrix. See AAP A ,r 4
( explaining prior to Appellants' invention, "the receiver will typically feed
back only an index (instead of the actual matrix entries) that points to the
appropriate codeword in the codebook( s) stored at the transmitter"). In
contrast, the Specification describes the invention "dynamically generat[ es]
the matrix codebooks rather than having them stored on the mobile device."
Spec. ,r 8.
Because the Examiner fails to provide sufficient evidence or
explanation to support the rejection, we are constrained by the record to
reverse the Examiner's rejection of claim 1.
Each of independent claims 8 and 16 recites a claim limitation that is
substantively similar to the disputed limitation of claim 1. See claims 8 and
16. Therefore, for similar reasons, we reverse the Examiner's rejection of
independent claims 8 and 16.
We also reverse the Examiner's rejection of corresponding dependent
claims 3-7, 10-15, and 18-20.
DECISION
We reverse the Examiner's decision rejecting claims 1, 3-8, 10-16,
and 18-20.
REVERSED
