Appeal No. 2006-1084
Reexamination Control No. 90/006,334
1 D. Findings of Fact (FF)
2 1. The invention is directed to a method and apparatus for
3 monitoring and controlling access by computer users to network resources.
4 (‘786 Patent, col. 1, lines 4-8.)
5 2. In the context of the invention, the management of an
6 organization may set a network access control policy for its employees for
7 two reasons: (1) maximizing employee productivity by ensuring that
8 Internet access is used primarily for business purposes, and (2) maximizing
9 the Internet-connection capability of the organization, particularly during
10 peak usage times. (‘786 Patent, col. 2, lines 9-15.) For example, the more
11 users are accessing the network, the more degraded the network accessing
12 capability becomes.
13 3. A traditional approach to providing access control is to apply
14 known firewall technology and focus on well-known data packet filtering
15 techniques, where no data packet is allowed to be forwarded without prior
16 filtering. (‘786 Patent, col. 2, lines 31-38.)
17 4. In modern networks, including the Internet, each node-to-node
18 transmission is divided into multiple data packets which are separately
19 transmitted to a destination node. At the destination node, the multiple
20 packets are assembled to form the original message. (‘786 Patent, col. 6,
21 lines 51-56.)
22 5. One sample data packet is illustrated in Figure 3 of the ‘786
23 Patent. (‘786 Patent, col. 6, lines 56-57.)
