STATEMENT OF THE CASE
This is an appeal under 35 U.S.C. § 134(a) from the Examiner’s final
rejection of claims 1-20, which are all the claims pending in the application.
We have jurisdiction under 35 U.S.C. § 6(b).
We affirm.

Representative Claim
1. An information handling system comprising:

a chassis having exterior walls, the walls having one or more blanks,
the blanks selectively removable for replacement by a component, the blanks
having venting;

a motherboard disposed in the chassis, the motherboard operable to
accept plural components, the components operable to cooperate to process
information;

a cooling fan disposed proximate the chassis, the cooling fan aligned
to provide cooling airflow across the components at variable fan speeds, the
fan speeds determined by reference to a thermal profile; and

a thermal profile manager interfaced with the cooling fan and operable
to select a thermal profile for the cooling fan based on whether a blank or a
component is present at the chassis wall.

Examiner’s Rejections
Claims 1-6, 10-14, and 16-19 stand rejected under 35 U.S.C. § 103(a)
as being unpatentable over Alperin, Lee, and Miyamoto.
Claims 7-9, 15, and 20 stand rejected under 35 U.S.C. § 103(a) as
being unpatentable over Alperin, Lee, Miyamoto, and Official notice.

ANALYSIS
Section 103 rejection of claims 1, 2, 5, and 6
Appellants contend that the combination of Alperin, Lee, and
Miyamoto does not teach “a thermal profile manager interfaced with the
cooling fan and operable to select a thermal profile for the cooling fan based
on whether a blank or a component is present at the chassis wall” as recited
in claim 1. In particular, Appellants contend that Alperin does not teach
management of thermal conditions based on venting available to cool
components. App. Br. 3-4; Reply Br. 1.
Alperin teaches that an operating curve selector automatically adapts a
cooling system by applying cooling system parameters for components of an
information handling system. ¶¶ 14, 17. Lee teaches that the components
can be blanks or filler cards that occupy slots in the absence of functional
electronic cards. ¶ 24. Miyamoto teaches that the blanks can provide
venting for a cooling air draft. Figs. 35, 36; col. 26, ll. 23-35. Alperin
further teaches that the nature and efficiency of the cooling air draft depends
on the presence of air shrouds or other devices to help direct airflow. ¶ 15.
Considering that the Examiner has shown the presence of components
that help direct airflow, such as the venting blanks taught by Lee and
Miyamoto, when applying cooling system parameters for components as

taught by Alperin, we find that the combination of familiar elements
according to known methods yields the predictable result of selecting a
thermal profile for a cooling fan based on whether a blank or a component is
present at the chassis wall.
Therefore, we sustain the rejection of claim 1 under 35 U.S.C. § 103.
Appellants do not present arguments for separate patentability of claims 2, 5,
and 6 which fall with claim 1.

Section 103 rejection of claims 7-9
Appellants do not present arguments for separate patentability of
claims 7-9, which fall with claim 1.

Section 103 rejection of claims 3 and 4
Appellants contend that Alperin does not suggest discovery of a blank
as opposed to discovery of a component. App. Br. 4; Reply Br. 2. Alperin
teaches discovery of components. ¶ 17. Lee (¶ 24) and Miyamoto (Fig. 36)
teach that the components can be venting blanks. Appellants’ arguments
attack Alperin individually, but do not sufficiently address the combined
teachings of Alperin, Lee, and Miyamoto. One cannot show non-
obviousness by attacking references individually, where the rejections are
based on combinations of references. In re Merck & Co., Inc., 800 F.2d
1091, 1097 (Fed. Cir. 1986); In re Keller, 642 F.2d 413, 425 (CCPA 1981).
Therefore, we sustain the rejection of claim 3 under 35 U.S.C.
§ 103. Appellants do not present arguments for separate patentability of
claim 4, which falls with claim 3.

Section 103 rejection of claims 10-14
Appellants contend that the combination of Alperin, Lee, and
Miyamoto does not teach “selecting a thermal profile based upon the
detected venting” as recited in claim 10. App. Br. 4; Reply Br. 2.
Appellants’ Specification discloses that venting is detected by determining
the presence of a venting blank. Spec. 6:30–7:20.
We find that the combination of Alperin, Lee, and Miyamoto teaches
“selecting a thermal profile based upon the detected venting” for the reasons
given in our analysis of claim 1. We sustain the rejection of claim 10 under
35 U.S.C. § 103. Appellants do not present arguments for separate
patentability of claims 11-14, which fall with claim 10.

Section 103 rejection of claim 15
Appellants do not present arguments for separate patentability of
claim 15, which falls with claim 10.

Section 103 rejection of claim 16
Appellants contend that Alperin does not teach “engaging a switch
with a blank coupled to the chassis” as recited in claim 16. App. Br. 5. The
Examiner finds Alperin teaches a CPU, which is a switch (Ans. 8), that
detects components (Ans. 4 (citing ¶ 17)). Appellants contend that the CPU
of Alperin does not engage a blank. Reply Br. 2.
We find that the CPU of Alperin is a switch that engages components.
The combination of Lee and Miyamoto teaches that the components can be
venting blanks. Appellants’ arguments attack Alperin individually, but do
not sufficiently address the combination of Alperin, Lee, and Miyamoto.

6
We sustain the rejection of claim 16 under 35 U.S.C. § 103.

Section 103 rejection of claims 17-19
Appellants contend that the combination of Alperin, Lee, and
Miyamoto does not teach “a thermal profile manager interfaced with the
cooling system and operable to select a thermal profile for the cooling
system based on detection of venting available through a wall of the chassis”
as recited in claim 17. App. Br. 5; Reply Br. 2. We find this argument
unpersuasive for the reasons given in our analysis of claim 1.
We sustain the rejection of claim 17 under 35 U.S.C. § 103.
Appellants do not present arguments for separate patentability of claims 18
and 19, which fall with claim 17.

Section 103 rejection of claim 20
Appellants do not present arguments for separate patentability of
claim 20, which falls with claim 17.

DECISION
The rejection of claims 1-6, 10-14, and 16-19 under 35 U.S.C. §
103(a) as being unpatentable over Alperin, Lee, and Miyamoto is affirmed.
The rejection of claims 7-9, 15, and 20 under 35 U.S.C. § 103(a) as
being unpatentable over Alperin, Lee, Miyamoto, and Official notice is
affirmed.
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. §
41.50(f).
