`Asserted Patent/Claim
`’770 Patent
`[1.Preamble] A method of
`providing telephone service,
`the method comprising:
`
`Anand
`
`
`To the extent the preamble is construed as limiting, Anand discloses “[a] method of providing
`telephone service, the method comprising[.]”
`
`“A telecommunications system includes a terminal adapted to couple to a telecommunications
`network. A memory is configured to store control procedures and data, and a processor is coupled to
`the memory and configured to execute the control procedures to communicate with the
`telecommunications network. When a call is placed from an initiator to a destination, and when the
`destination is not available, the processor is configured to store profile data associated with the
`initiator for the destination to return the call when the destination is available. In one aspect of the
`invention, the processor is further configured to provide audio interaction to the initiator and to record
`the profile data in response to the initiator's actions. Advantages of the invention include the ability
`to track and respond to all calls in order to provide high quality communication features and customer
`service.” Anand at Abstract.

`
`[1.A] associating a
`secondary telephone number
`with a primary telephone
`number in at least one
`computer memory device,
`the primary telephone
`number being assigned to a
`handset;
`
`To the extent this reference does not expressly disclose this limitation, it inherently discloses the
`limitation. To the extent this reference does not expressly or inherently disclose this limitation, it
`renders the limitation obvious in light of the reference by itself or in combination with other
`references, as described in Defendant’s invalidity contentions.
`Anand discloses “associating a secondary telephone number with a primary telephone number in at
`least one computer memory device, the primary telephone number being assigned to a handset[.]”
`
`“In an aspect of the invention, the system stores data 214 for each registered user. This data is used
`by the system to determine the priority of telephone numbers to call, the status of the call-backs, the
`type of call back notification the registered user prefers as well as language preference, marketing
`preference, disconnect preference and others. Since each of the users has a personal identification
`number (PIN), the users can each modify their respective information in a number of ways. One way
`is by calling a customer service representative and having them change the information. Another way
`is over the telephone using the PIN by pressing the keypad and then interacting with the system to
`modify or confirm the information. Still another way is over a network interface such as an Internet
`interface. This way, the user can call up a browser and interact with the system via the network. A
`personal computer browser such as Netscape or Microsoft can be used as well as a wireless browser
`such as one from Palm Computing, Phone.com or other vendor.” Anand at 4:26-5:5.
`
`“By modifying the data, the user can make it convenient for both the caller and the destination. The
`destination person will return the call to the phone or other device where the user is most-likely
`located. For example, the user might prefer to be called on a cell phone and then switch over to a
`land phone. In one aspect of the invention, the data includes a parameter that identifies the time for
`which the system will call the primary, secondary, tertiary or other number. For example, a user may
`want to be called during business hours only, or the user may prefer to be called one a cell phone or
`at home after business hours. In this case, the call is either disconnected or taken off the queue once
`those conditions are satisfied. In another example, the user can instruct the call waiter to make a
`predetermined number of attempts (e.g. redials at predetermined intervals) and then disconnect or be
`taken off the queue.” Id. at 5:6-16.

`data structure 214 for a caller. This includes the last name, first name, primary telephone number,
`primary telephone number, secondary telephone number, tertiary telephone number, status updates
`(Y/N), status updates, status update mode, phone/e-mail/web/fax,
`language preference,
`marketing/advertising (Y/N), Disconnect after x minutes, and personal identification numbers
`(PIN).” Id. at 3:29-4:11.
`
`“In an aspect of the invention, the system stores data 214 for each registered user. This data is used
`by the system to determine the priority of telephone numbers to call, the status of the call-backs, the
`type of call back notification the registered user prefers as well as language preference, marketing
`preference, disconnect preference and others. Since each of the users has a personal identification
`number (PIN), the users can each modify their respective information in a number of ways. One way
`is by calling a customer service representative and having them change the information. Another way
`is over the telephone using the PIN by pressing the keypad and then interacting with the system to
`modify or confirm the information. Still another way is over a network interface such as an Internet
`interface. This way, the user can call up a browser and interact with the system via the network. A
`personal computer browser such as Netscape or Microsoft can be used as well as a wireless browser
`such as one from Palm Computing, Phone.com or other vendor.” Id. at 4:26-5:5.
`
`“By modifying the data, the user can make it convenient for both the caller and the destination. The
`destination person will return the call to the phone or other device where the user is most-likely
`located. For example, the user might prefer to be called on a cell phone and then switch over to a
`land phone. In one aspect of the invention, the data includes a parameter that identifies the time for
`which the system will call the primary, secondary, tertiary or other number. For example, a user may
`want to be called during business hours only, or the user may prefer to be called one a cell phone or
`at home after business hours. In this case, the call is either disconnected or taken off the queue once
`those conditions are satisfied. In another example, the user can instruct the call waiter to make a
`predetermined number of attempts (e.g. redials at predetermined intervals) and then disconnect or be
`taken off the queue.” Id. at 5:6-16.
`
`“In another aspect of the invention, the parameter can be set to a specific number of call-backs before
`failing. Moreover, since the data includes a field for the preferred method of notification, e.g. by
`phone, e-mail, fax, etc., the system will try to reach the user in the way most-likely to succeed for
`that particular user. Since users are different and may prefer different types of notification, the

`
`inventive system is optimized for each particular user. Finally, If there is a failure of the system to
`have the destination return the call, the call waiter can send the failure notice to the user using the
`method best for the user. In one aspect of the invention, in case of a failed call return, the system can
`give the user the option of leaving a message for the destination that describes the nature of the call.”

`“Figure 6 depicts a call waiter for use with a small business distributor according to an embodiment
`of the invention. In this embodiment, a small business subscribes to the call waiter 200 services. The
`call waiter 200 assigns one or more telephone numbers to each of the business subscribers. When an
`initiator calls the business, the call waiter monitors the call and answers the telephone if the
`destination is not available. As soon as the destination becomes available, the call waiter notifies the
`destination and places a call to the initiator.” Id. at 6:12-18.

`“Figure 9 depicts a call waiter combined with an Internet communications network according to an
`embodiment of the invention. It is anticipated that all the features and functions previously described
`are equally applicable to this embodiment, for example, voice over IP, net-phone software or other
`technology that involves audio streaming over the Internet. In this embodiment, the initiator 110 is
`coupled to the Internet 420, and to an automatic call distributor 430 to a destination 440, 450. If the
`call is made from the initiator 110 to the destination 430, then the call is handled much in the same
`way described above, but with the substitution of the Internet 420 as the telecommunications
`network. In this case, a bridge 500 between the Internet 420 and the PSTN 120 can be provided to
