or, in some cases the nature of the problem to be solved.” In re Huston 308 F.3d
1267, 1278, 64 USPQ2d 1801, 1810 (Fed. Cir. 2002, citing In re Kotzab 217
F.3d 1365, 1370, 55 USPQ 1313, 1317 (Fed. Cir. 2000)).
We find that Moss teaches that prior methods of inserting expansion cards
into a computer chassis required the chassis to be opened and the cards to be
vertically inserted onto the motherboard. See column 1, line 9-15 and column 2,
line 45-59. Moss teaches that an improvement to this method is to use an
expansion card carrier, which is inserted into the chassis horizontally. See
column 3, line 53 to 65, and figure 7 and 10. While we concur with appellant that
Moss discloses one of the advantages of the horizontally inserted expansion card
carrier is that it has the ability to replace cards in a live chassis, we do not find
that this is the only problem to be solved. Moss also discloses that the problem
with vertical insertion is that it is time consuming because it requires removal of
the chassis cover.
Moss teaches that the system to horizontally insert cards can be used with
PCI expansion cards. However, Moss does not teach how the PCI expansion
cards are secured to the carrier. See Column 3, lines 11-15. We note that Moss
does not define a PCI card, however appellant’s specification, on page 1,
identifies that one industry standard for expansion cards is Peripheral
Component Interconnect (PCI). We find that a skilled artisan would recognize
that in a computer system, many peripheral components, such as a printer,
monitor, scanner, etc., are located outside of the computer chassis, as such PCI
