Appeal 2007-1102
Application 10/006,692
Chiloyan discloses a system for obtaining a driver for a peripheral
device connected to a personal computer (PC).6 When the user connects a
peripheral device to USB I/O interface 46, the PC’s operating system 35
detects and enumerates the newly-connected peripheral to extract a device
descriptor from the peripheral. The device descriptor contains data fields
relating to the peripheral including a vendor ID and a product ID. These IDs
are then parsed from the device descriptor fields and used to determine the
network address from which the peripheral’s drivers can be obtained
(Chiloyan, ¶¶ 0036-37; Figs. 1 and 2). To this end, the vendor ID and/or
product ID can serve as indexes into a local or remote database to reference
a network address related to the peripheral (Chiloyan, ¶¶ 0044-45). Using
the obtained network address, the driver for the peripheral can then be
downloaded from a remote device accessible at the network address
(Chiloyan, ¶ 0041; Abstract).
PRINCIPLES OF LAW
Anticipation is established only when a single prior art reference
discloses, expressly or under the principles of inherency, each and every
element of a claimed invention as well as disclosing structure which is
capable of performing the recited functional limitations. RCA Corp. v.
Applied Digital Data Systems, Inc., 730 F.2d 1440, 1444, 221 USPQ 385,
388 (Fed. Cir. 1984); W.L. Gore and Associates, Inc. v. Garlock, Inc., 721
F.2d 1540, 1554, 220 USPQ 303, 313 (Fed. Cir. 1983).
6 PC 20 may operate in a networked environment such as that found in
offices, intranets, etc. (Chiloyan, ¶¶ 0031-32).
