Reexamination Control No. 90/005,742
Patent 5,253,341
1 teachings the examiner is proposing to combine with Filepp.43 The rejection of claim 11 for
2 obviousness over Filepp in view of "well known practices" as evidenced by De Maine, Carr,
3 Giltner, Notenboom, and LeGall is therefore reversed.
4 (4) Claims 9, 10, and 14 – obvious over Filepp in view of Row?
5 The rejection relies on the "Background of the Invention" portion of Row (cols. 1-3)
6 rather than on the detailed description of Row's invention. Row explains that "[p]resent-day
7 network clients and servers usually run the DOS, MacIntosh OS, OS/2, or Unix operating
8 systems," col. 1, ll. 51-53, and that
9 Unix client nodes typically feature a 16- or 32-bit microprocessor
10 with 1-8 MB of primary memory, a 640x1024 pixel display, and a built-in
11 network interface. A 40-100 MB local disk is often optional. Low-end
12 examples are 80286-based PCs or 68000-based MacIntosh I's; mid-range
13 machines include 80386 PCs, MacIntosh II's, and 680X0-based Unix
14 workstations; high-end machines include RISC-based DEC, HP, and Sun
15 Unix workstations.

17 Id. at col. 1, l. 62 to col. 2, l. 2. These characteristics apply to servers as well as to clients:
18 “Servers are typically nothing more than repackaged client nodes, configured in 19-inch racks
19 rather than desk sideboxes." Id. at col. 2, ll. 2-4. Row further explains that “[d]riven by RISC
20 and CISC microprocessor developments, client workstation performance has increased by more
21 than a factor of ten in the last few years.” Id.at col. 2, ll. 7-9.
22 The examiner argues that "[i]t would have been obvious . . . to replace the mainframe
23 used by Filepp et al. with a remote host utilizing a RISC or CISC based processor in view of the

(not including the claims and a printout of a program listing).
