`including its brief in support of its request for ex parte reexamination. a supporting declaration,
`
`claim charts, its comments on Net2Phonc*s validity expert's opinions, and the parties* claim

`ABSTRACT
`
`A point-to-point Internet protocol exchanges Internet Pro
`tocol (IP) addresses between processing units to establish a
`point-to-point communication link belween the processing
`units through the Internet. A first point-to-point Internet
`protocol includes the steps of (a) storing in a database a
`respective IP address of a set of processing units that have
`an on-line status with respect to the Internet; (b) transmitting
`a query from a first processing unit to a connection server to
`determine the on-line status of a second processing unit; and
`(c) retrieving the IP address of the second unit from the
`database using the connection server, in response to the
`determination of a positive on-line status of the second
`processing unit, for establishing a poinl-lo-poinl communi
`cation link between the first and second processing units
`through the Internet. A second point-to-point Internet pro
`tocol includes the steps of (a) transmitting an E-mail signal,
`including a lirst IP address, from a first processing unit; (b)
`processing the E-mail signal through the Internet to deliver
`the E-mail signal to a second processing unit; and (c)
`transmitting a second IP address to Ihe first processing unit
`lor establishing a point-to-point communication link
`belween Ihe first and second processing units through the
`
`Internet.

`
`The increased popularity of on-line services such as
`AMERICA ONUNli™, COMPUSERVE®, and oilier scr-
`vices such as Internel gateways have spurred applications lo
`provide multimedia, including video and voice clips, to
`
`online users. An example of an online voice clip application
`is VOICE E-MAIL FOR WINCIM and VOICE E-MAIL
`FOR AMERICA ONLINE™, available from ISonzi
`Software, as described in "Simple Utilities Send Voice
`E-Mail Online", MULTIMEDIA WORLD VOL. 2 NO. 9.
`August 1995, p. 52. Using such Voice E-Mail soltware, a
`
`user may create an audio message to be senl to a predeter-
`mined E-mail address specihed by the user.

`processing unit, for establishing a point-lo-point com-
`munication link between the first and second process-
`inS units through the Internel.
`A sc.cond point-to-point Internet protocol is disclosed,
`which includes the sleps of:
`
`(«) transmitting an E-mail signal, including a first IP
`address, from a lirsl processing unit;
`
`^ (b) processing the E-mail signal through Ihe Internel lo
`deliver the E-mail signal to a second processing unit;
`and

`
`to convey lext, audio, etc., with any routing information
`such as a'n IP address and rouling headers generally being
`considered an arlifucl of ihe communication, or even gib-
`berish lo ihe recipient.
`
`Devices such as a host computer or server of a company
`may include multiple modems for connection of users lo Ihe
`lnlernet, with a temporary IP address allocated to each user.
`For example, Ihe host computer may have a general IP
`address "XXX.XXX.XXX", and each user may he allocated
`
`xxx xxx XXX n txxxxxvyv n***"?X,X,'!°'
`
`XXa.XXX.XXX.1I, XXX.XXX.XXX. 12, etc. Such tern-
`porary IP addresses may be reassigned ot recycled to ihc
`users, for example, as each user is successively connected to
`an outside party. For example, a host computer of a company
`may support a maximum of 254 IP addresses which are
`pooled and shared between devices connected to the host
`
`computer.
`
`Permanent IP addresses of users and devices accessing the
`Internel readily support point-lo-point communications of
`voice and video signals over the Internet. For example,
`realtime video teleconferencing has been implemented using
`dedicated IP addresses and mechanisms known as reflectors.
`Due lo the dynamic nature of temporary IP addresses of
`some devices accessing the Internet, point-to-point column-
`nicalions in realtime of voice and video have been generally
`difficult lo attain.

`The processor 14 receives input commands and dan from

`
`For callee (or called) processing units wilh fixed IP
`addresses, the caller (or calling) processing unit may open a
`"socket", i.e. a file handle or address indicating where dala
`is lo be sent, and transmit a <Call> command to establish
`communication with thc callee utilizing, for example, data
`gram services such as Inlernet Standard nelwork layering as
`well as transport layering, which may include a Transport
`Conlrol Protocol (TCP) or a User Datagram Protocol (UI)P)
`on top of the IP. Typically, a processing unit having a fixed
`IP address may maintain at least one open socket and a
`called processing unil waits for a <Call> command to assign
`Ihe open socket to the incoming signal. If all lines are in use,
`the callee processing unil sends a BUSY signal or message
`to Ihe caller processing unit.
`
`As shown in FIG. 1, Ihe disclosed point-to-poinl Internet
`
`prolocol and system 10 operate when a callee processing
`unil does not have a fixed or predelermined IP address. In lhc
`exemplary embodiment and without loss of generality, Ihe
`first processing unit 12 is the caller processing unit and Ihe
`
`second processing unit 22 is the called processing unil.
`
`When eilher of processing units 12, 22 logs on lo the
`Internet via a dial-up connection, the respective unit is
`provided a dynamically allocated IP address by a connection
`service provider.
`
`Upon the first user initialing lhc point-to-point Internet
`protocol when the first user is logged on to Internet 24, Ihe
`first processing unit 12 automatically transmits its associated
`E-mail address and its dynamically allocated IP address to
`the connection server 26. The connection server 26 then
`siorcs these addresses in the database 34 and limestamps Ihe
`slored addresses using timer 32. The first user operating lhc
`first processing unit 12 is thus established in the database 34
`
`as an active on-line party available for communication using
`the disclosed poinl-lo-poinl Internet prolocol. Similarly, a
`second user operating Ihe second processing unit 22, upon
`connection lo the Inlernet 24 through a connection service
`provider, is processed by Ihe connection server 26 lo be
`
`established in thc dalabase 34 as an active on-line parly.
`
`If the callee is nol on-line when lhe connection server 26
`determines lhe callee's status, the connection server 26
`sends an OFF-I .INE signal or message to the first processing
`unil 12. Hie first processing unit 12 may also display a
`j message such as "Called
