FINDINGS OF FACT AND CONCLUSIONS OF LAW

WILKEN, District Judge.

I. FINDINGS OF FACT

A. BACKGROUND

(1) This is a patent infringement action in which Plaintiff Telemac Corporation (Telemac) asserts that Defendant US/Inte-licom, Inc. (USI) infringed claims 7, 10 and 11 of Telemac’s U.S. Patent No. 5,577,100 (’100 patent). In view of this Court’s April 27, 2001 “Order On Cross-Motions For Summary Judgment,” the only remaining issue concerns the “communication means” claim element. On May 29 and 30, 2001, this Court held a trial to resolve whether USI or its licensees have or have had “communication means for selectively establishing a communication link” within the meaning of independent claim 1 of Telemac’s TOO patent and, if so, what measure of damages Telemac is entitled to recover for infringement by USI of dependent claims 7, 10 and 11 of Telemac’s TOO patent. (May 11, 2001 “Stipulation And Order Concerning Trial”).

(2) The TOO patent discloses and claims technical improvements in the field of wireless telephone technology. Conventional cellular phones operate on a credit system similar to a credit card. The cellular phone carrier permits customers to use its airwaves and amass charges. At the end of the month, the carrier sends a bill for the amount of the charges. This system operates on the assumption that the customer is creditworthy, and thus excludes those with poor credit ratings. (April 27, 2001 “Order On Cross-Motions For Summary Judgment”, p. 2).

(3) Telemac is a Delaware corporation with its principal place of business in California. When the company was formed in the early 1990’s, it focused on the rental cellular phone market and sought to find a way to minimize the credit risk for the rental provider. Telemac developed a cellular telephone accounting system, described in U.S. Patent No. 5,325,418 (’418 patent), which allows phones to record the phone number and call duration for each call as it is made. When the customer returns the phone, the rental provider uses the stored information to prepare and present a bill in order to receive immediate payment. (April 27, 2001 “Order On Cross-Motions For Summary Judgment”, p. 2-3; TEx. 5 1 , ’418 Patent).

(4) In 1992, Telemac began work on the switch-independent debit telephone technology which is the subject of the TOO patent. This technology was intended to reduce further the credit risk to the cellular airtime provider by permitting prepayment by customers. Telemac developed a mobile phone system that: (1) stored rate information for different types of calls within the telephone, (2) used a complex billing algorithm stored within the telephone to apply the appropriate rate to each call and determine the actual charges for the call, and (3) used a debit account stored within the telephone to subtract charges for the call from a prepaid account amount. (April 27, 2001 “Order On Cross-Motions For Summary Judgment”, p. 3; TEx. 1, TOO Patent).

B. TOO PATENT’S “COMMUNICATION MEANS”

(5) The debit telephone system described in Telemac’s TOO patent features a system provider with one or more computers, known as “host processors.” The host processors perform programming, activa *1088 tion and debit account funding functions. In one embodiment, the host processor takes the form of the personal computer illustrated in Figure 1 of the ’100 patent. In another embodiment, the host processor either “comprises the central processing unit 14 of Fig. 1 or a satellite computer that is preferably connected to the central processing unit 14.” (TEx.l, 8:15-19). A similar arrangement of multiple central and satellite host processors is illustrated in Figure 2 of the ’418 patent which is incorporated by reference. In the case of the ’418 patent, the multiple host processors include a central server and a plurality of satellite personal computers. Through these individual or multiple host processors, the system provider can communicate directly with the mobile telephone to activate and program the mobile telephone or to replenish the telephone’s debit account. (April 27, 2001 “Order On Cross-Motions For Summary Judgment”, p. 2-3; TEx. 1,100 patent, Fig. 1,1:15-18, 3:56, 6:7-9, 6:22-25; TEx. 5, Fig. 2, 5:5-40; Bristow Tr. 2 , 80-81).

(6)The 100 patent specification discloses both “automatic” and “manual” embodiments for a system provider’s host processors to communicate with a mobile telephone unit. The “automatic” embodiments include either direct “hard wire” or “over-the-air” data connections between the host processor and the mobile telephone unit. In both these automatic embodiments, the host processor enables the operation of the cellular phone by initiating communications and transmitting operating codes to the phone without human intervention. The manual approach, alternatively, requires the user to call an operator at the system provider’s service center and verbally receive host processor activation codes from the operator. The user then manually enters these codes into the telephone through the telephone keypad. (TEx. 1, 100 patent; Telemac Cellular Corp. v. Topp Telecom, Inc., 247 F.3d 1316, 1320 (Fed.Cir.2001)).

(7) The 100 patent discloses several structural embodiments for establishing a direct “hard wire” communication between a host processor and a mobile telephone unit. One of these embodiments involves an interlink receiver boot connected by wire to the host processor. The mobile telephone unit can be inserted into this interlink receiver boot to achieve a direct, electrical coupling with the host processor. In a second “hard wire” embodiment, “satellite processors for activating and programming phone units require only a personal computer with a modem and a bus connect to the connection port of the phone unit.” (TEx.1, 3:56-59). This second “hard wire” embodiment achieves the same type of physical connection between the host processor and the mobile telephone unit. (TEx. 1, 100 patent, Fig. 1, 3:48-67, 8:36-38; Telemac Cellular Corp., 247 F.3d at 1320; Bristow Tr. 73-76).
