Pursuant to Paragraph 3 of the July 31, 2007 Scheduling Order, Plaintiffs Cisco Systems Inc. and Cisco Technology Inc. (collectively "Cisco") and Defendant Telcordia Technologies, Inc. ("Telcordia") jointly submit this Final Joint Claim Chart. The parties have agreed on the following constructions: United States Patent No. 6,377,988, Claim 1 1. "predetermined function" in claim 1 means "a function that has been

determined beforehand." United States Patent No. 5,142,622, Claim 7 1. "network domain" in claim 7 means "the address family of a socket, and

not a domain-naming domain. A domain naming domain is a concept of a related group of hierarchical addresses, wherein each part of the address is separated by a delimiter such as a period." 2. "network protocol architecture" in claim 7 means "network domain."

socket

an object that identifies a communication end point in an application program interface (API) that was a network developed for the Berkeley version of AT&T's UNIX operating system for interconnecting applications Col. 2, ll. 27-28 running on data processing systems in a network. It is an object that identifies a communication end point in a network, can be connected to other sockets, and hides the protocol of the network architecture beneath a lower layer Col. 2, ll. 23-37; June 29, 1990, Amendment at 11.

routing facility

a facility that establishes a connection between the sockets in the first and second data processing systems

an intermediate facility in a socket layer that includes a routing agent software, a socket routing protocol, and a route database or cache for establishing sockets in the facility, and then establishing at the socket layer a connection between sockets in first and second data processing systems that each operate in a different network domain Col. 3, ll. 48-52, 62-64; Col. 4, ll. 3-5; Col. 5, ll. 2-5, 32-33; Col. 5, L. 51-Col. 6, L. 2 ; Col. 10, ll. 43-45; Figure 1; Figure 7.

Claim Term

Cisco's Proposed Construction and Supporting Intrinsic Evidence a communication path between a first socket and second socket

Telcordia's Proposed Construction and Supporting Intrinsic Evidence a communication path between a first socket and a second socket with an intermediate routing facility between the first socket and the second socket, the routing of the communications being performed at a layer that contains the sockets Col. 3, ll. 48-52, 62-64; Col. 4, ll. 3-5, 16-18; Col. 5, ll. 2-5.

socket connection

data processing system

a system for executing application programs January 24, 1991, Amendment at 5

a system, including computer systems and associated personnel, that performs input, processing, storage output, and control functions to accomplish a sequence of operations on data, excluding a terminal January 24, 1991, Amendment at 5. Extrinsic Evidence: IEEE Standard Dictionary of Electrical and Electronics Terms, Sixth Edition (April 1997).

means for mapping protocols between said first and second network domain

This claim element is a means-plus function limitation subject to 35 U.S.C. § 112(6). The claimed function is mapping protocols between the first and second network domain. The corresponding structure is software within socket layer 32 as described at 9:30-11:19.
