`II.
`
`IDENTIFICATION OF CLAIMS FOR WIDCH RE-EXAMINATION IS REQUESTED
`
`In accordance with 37 CFR 1.51 0, re-examination is requested for claims 1 and 58 of
`
`U.S. Patent No. 7,149,511 ("the '511 patent"), which is entitled "Wireless Intelligent Personal
`
`Server." Specifically, re-examination of claims 1 and 58 of the '511 patent is requested.
`
`III.
`
`STATEMENT POINTING OUT EACH SUBSTANTIAL NEW QUESTION OF
`
`PATENT ABILITY
`
`A new question of patentability as to claims 1 and 58 is raised by Exhibit F, which is
`
`cited in the accompanying PTO 1449 form. It appears that Exhibit F suggests a teaching of
`
`the feature "a first interface for allowing an external device to selectively access said at least
`
`one electronic file" as recited in claims 1 and 58. Exhibit F was not present during the prior
`
`examination of the patent under reexamination. Requestor believes that a reasonable
`
`examiner would consider the teaching suggested by Exhibit F important in determining
`
`whether or not claims 1 and 58 are patentable because it was not present during the prior
`
`examination of the patent under reexamination.
`
`A new question of patentability as to claims 1 and 58 is raised by Exhibit G, which is
`
`cited in the accompanying PTO 1449 form. It appears that Exhibit G suggests a teaching of
`
`the feature "a first interface for allowing an external device to selectively access said at least
`
`one electronic file" as recited in claims 1 and 58. Exhibit G was not present during the prior
`
`examination of the patent under reexamination. Requestor believes that a reasonable
`
`examiner would consider the teaching suggested by Exhibit G important in determining
`
`whether or not claims 1 and 58 are patentable because it was not present during the prior
`
`examination of the patent under reexamination.
`
`A new question of patentability as to claims 1 and 58 is raised by Exhibit E, which is
`
`cited in the accompanying PTO 1449 form. It appears that Exhibit E suggests a teaching of
`
`the feature "a first interface for allowing an external device to selectively access said at least
`
`one electronic file" as recited in claims 1 and 58. Exhibit E was not present during the prior
`
`examination of the patent under reexamination. Requestor believes that a reasonable
`
`examiner would consider the teaching suggested by Exhibit E important in determining
`
`whether or not claims 1 and 58 are patentable because it was not present during the prior

`
`A new question of patentability as to claims 1 and 58 is raised by Exhibit I, which is
`
`cited in the accompanying PTO 1449 form. It appears that Exhibit I suggests a teaching of
`
`the feature "a first interface for allowing an external device to selectively access said at least
`
`one electronic file" as recited in claims 1 and 58. Exhibit I was not present during the prior
`
`examination of the patent under reexamination. Requestor believes that a reasonable
`
`examiner would consider the teaching suggested by Exhibit I important in determining
`
`whether or not claims 1 and 58 are patentable because it was not present during the prior
`
`examination of the patent under reexamination.
`
`A detailed explanation of the pertinency and manner of applying each of the prior art
`
`references with regard to claims 1 and 58 of the '511 patent, for which re-examination is
`
`requested, is set forth below.
`
`IV.
`
`DETAILED EXPLANATION OF PERTINENCE OF PRIOR ART
`
`The following identifies what the Requestor believes to be the pertinence and manner of
`applying each of the prior art references to claims 1 and 58 of the '511 patent. 1
`
`A. General Description: Nokia 9xxx Series of "Communicators"
`
`The original "Communicator" was the Nokia 9000, which was introduced in August,
`
`1996. In September of 1998 the Nokia 9110 was introduced. The 911 Oi was introduced four
`
`months later, and is the most recent unit prior to Applicant's patent application. Note: the
`
`suffixes on the 9110 model number (e.g., "i") represent only different frequencies of
`
`operation as required for a specific country. Except for frequencies, these two models are
`essentially identical.2
`
`The 9110 series offered improvements over the original 9000 series: sleeker design,
`
`1 Third Party did not provide, for each prior art reference, an element-by element comparison
`to each claim feature of claims 1 and 58 of the '511 patent. The Third Party only opined
`that the Nokia 9xxx Series Communicators teaches the feature "allowing an external display
`device to selectively access said at least one electronic file" as recited in claims 1 and 58.
`2 Instruction manuals ("User Guides") for the 9110 and 9110i models are also essentially
`identical; hence, only the Nokia 9110 User Guide is presented herein (Exhibit 'D').

`
`

`
`backlight screen, faster processor, slot for a memory card, resolution higher on the secondary
`
`display, and higher capacity battery for longer life between charges. It was also much lighter.
`
`Functionally, the only notable software addition was picture transfer via infrared. The Nokia
`
`9110i Communicator ("the Communicator") is a versatile, self-contained communications
`
`tool for staying connected to the office when traveling.
`
`The Communicator includes a cell phone, messaging device, mobile terminal, and
`
`palmtop organizer all in one compact unit. The Communicator's applications are designed to
`
`work together to provide the user with information when it's needed.
`
`B. The Pertinence and Manner of Applying the Prior Art References to Claims 1
`
`and 58 of the '511 Patent.
`
`For a detailed explanation of the pertinence and manner of applying the prior art
`
`references identified on the accompanying PTO 1449 form, please see the claim chart
`
`attached as Exhibit J.
`
`Requestor does not believe that any of the prior art identified on the accompanying PTO
`
`1449 form renders claims 1 or 58 ofthe '511 patent unpatentable when considered alone or in
`
`combination with one another and will reserve its analysis of patentable distinctions until and
`
`depending on a re-examination of the '511 patent proceeding on the merits.
`
`V.
`
`PROPOSED REJECTIONS
`
`The proposed rejections for claims 1 and 58 for which reexamination is requested are
`
`as follows:
`
`• Claims 1 and 58 appear to be unpatentable over Exhibits C and Din view of
`
`Exhibit F.
`
`• Claims 1 and 58 appear to be unpatentable over Exhibits C and D in view of
`
`Exhibit G.
`
`• Claims 1 and 58 appear to be unpatentable over Exhibits C and H in view of
`
`Exhibit D.
`
`• Claims 1 and 58 appear to be unpatentable over Exhibits C and Din view of
`
`Exhibit I.
`

`
`

`
`• Claims 1 and 58 appear to be unpatentable over Exhibits C and D in view of
`
`Exhibit E.
`

`
`CONCLUSION
`
`The $2,520.00 Ex Parte Reexamination request fee was previously paid with the
`
`submission of the original Reexamination request. Therefore, no fees are believed to be due
`
`at this time. However, the Commissioner is hereby authorized to charge any insufficiency, or
`
`credit any overpayment associated with this request to Murphy & King, P.C. Deposit Account

`
`ABSTRACT
`
`A wireless intelligent personal server includes a radio fre(cid:173)
`quency (RF) receiver, a memory for storing electronic files,
`a set of embedded machine language instructions, a central
`processing unit (CPU), a first interface for a display device,
`such as a personal digital assistant (PDA), and a second
`interlace for a wireless telephone. T he RF receiver receives
`downstream data transmitted over a downstream wireless
`communications channel. The CPU executes the machine
`language instmctions to process the downstream data and,
`thereby, either update au existing target electronic file stored
`in the memory, so that the target electronic file reflects
`changes made to a source electronic file, or create a new
`electronic file in the memory. A display device may be
`brought into communication with the wireless intelligent
`personal server, via the first interface, to access the elec(cid:173)
`tronic mes stored in the memury. The win::less intelligent
`personal server may also transmit an upstream signal over ru1
`upstream wireless communication channel, such as by using
`a wireless telephone, in communication via the second
`interface. The upstream signal may acknowledge receipt of
`the downstream data. or it may include upstream daw
`reflecting changes to the electronic files stored in the
`memory made by the display device.

`WIRELESS INTELLIGENT PERSONAL
`SERVER
`
`BACKGROUND OF THE INVENTION
`
`A. Field of the .Invention
`This invention relates to the field of wireless telecommu(cid:173)
`nications. More particularly, tllis invention relates to a
`wireless intelligent personal server that receives data trans(cid:173)
`mitted over a wireless communications channel and auto(cid:173)
`matically processes it so as to maintain a copy of at least one
`electronic fi le stored in a source computer.
`B. Description of Related A.ri
`A typical modem office uses a number of different data(cid:173)
`bases of infom1ation that are frequently updated. Examples
`of such databases include schedules, contact lists, price lists,
`real estate lists, and incoming e-mails. Such databases are
`typically stored as electronic files on eitl1er an oftlce-wide
`server or on individual personal computers located in the
`office space. Typically, individual workers in the office space
`are able to use personal computers, usually with network
`connections, to access the databases. More particularly. the
`personal computers typically nm applications that retrieve
`the desired infom1ation from the databases and display it to
`the user. With this configuration, the most up-to-date ver(cid:173)
`sions of the databases are typically available to the indi(cid:173)
`vidual workers, even though the electronic database files are
`frequently updated.
`However, many workers often work outside of the office
`environment at .least one day per week. ru1d, typically, it is
`more ditlicuJt to gain access to the most up-to-date versions
`of important electronic fi les when outside of the office
`environment. A currently used solution is to use portable
`computers to "dia l in" to tbe o:tllce network using the PSTN,
`Internet, or other wireline networks. However, mobile work(cid:173)
`ers do not always have access to wireline connections at all
`desired times. Accordingly, wireless communications sys(cid:173)
`tems have been developed by which mobile workers can
`access their office databases even without a wireline con-
`nection. As an example, some wireless telephones are able 40
`to send and receive limited amounts of data using the
`wireless application protocol (WAP).
`However, most of these wireless communications
`approaches, including the WAP approach, use a "pull"
`methodology, whereby the user first requests the information
`and then waits for a response. This "pull" methodology has
`the disadvantage of high latency and, typically, high cost.
`The high latency arises from the delay that typically occurs
`in each step of the process of retrieving the desired infor(cid:173)
`mation. ln particular, there is the time spent entering the 50
`keystrokes needed to make the request, U1e airtime spent
`transmitting the request. the delay in having the request
`reaching the office network through intermediate networks,
`the delay in having the office network search through its
`databases to formulate a response, and the delay in trans- 55
`mittiug the response through the intermediate networks and
`then over the air interface. The high latency is not only
`troublesome to tl1e user; it leads to high costs due to U1e
`airtime needed to process the request ru1d the response.
`]l1e problem becomes more acute the more interactive the 60
`transaction becomes. A user using WAP to retrieve a new
`e-mail message with an attachment provides a simple illus(cid:173)
`tration o.fthe problem. First, tbe user requests the new e-mail
`message and receives it after waiting for the latency period
`described above, for which the user is typically charged 65
`airtime. Second, tbe user reads the new e-mail message and
`sees tl1at it has an attachment. Then the user must make
`
`2
`another request to receive the attachment. The user waits for
`another latency period to receive it, tbereby typically incur(cid:173)
`ring additional airtime charges. Moreover, the latency period
`may be quite long, because files attached toe-mails are often
`quite large. Accordingly, ex.isting"pull" approaches, such as
`WAP have substantial disadvantages.
`Another problem with many technologies for receiving
`data over wireless chalUlels is that they are highly device(cid:173)
`specific, i.e., they are based on providing wireless function-
`to ality to existing devices, such as specific models of personal
`digital assistants (PDAs). However, there are a number of
`problems with device-specific approaches. First, many
`people use different computing devices at different times, so
`that providing only one ofthe user's computing devices witl1
`t5 w ireless functionality is, at best, only a part·ial solution.
`Second, different computing devices differ in their abilities
`to handle different types of data. For example, desb.'top PCs
`typically have much more memory than PDAs, and desktop
`PCs often have access to high quality monitors, speakers,
`20 and peripherals to display information and provide function(cid:173)
`ality to the user in ways U1at are unavailable to typical PDAs.
`On tl1e other hand, PDAs also have many advantages over
`a desktop PC, such as portabi lity. In addition to the avail(cid:173)
`ability of d.iB'erent hardware, different computing devices
`25 may have different operating systems and applications avail(cid:173)
`able to them. Accordingly, approaches that provide wireless
`functionality onJy to specific devices have substantial dis(cid:173)
`advantages.
`For exan1ple, Kaufman, U.S. Pat. No. 6,034,621, dis-
`30 closes systems <llld metl1ods for conuuunicating changes
`made to a data fi le on a personal computer (PC) to a personal
`digital assistant (PDA). In accordance with some of the
`disclosed embodiments, when the data file on the PC is
`changed, synchroni7..ation information is transmitted over a
`35 paging network to a pager that is couuected to the PDA, such
`as by a serial or parallel connection. A synchronization
`routine in the PDA then interacts with the synchronization
`iufonuation output from the pager to update the data file in
`the PDA.
`While potentially reducing U1e latency problem, at least
`for small amow1ts of data, the Kaufmru1 approach suffers
`from a number of disadvantages. First. PDAs are not typi(cid:173)
`cally on all of the time. Thus, update information may be
`missed because of the PDA heiug off. Second, PDAs typi-
`45 cally have a very limited memory, i.e., 8 megabytes or less.
`Because of this limited memory, mobile workers may not be
`able to access some oftl1e very large electronic files that they
`can access at their offices.

`downstream data transmitted over a wireless conumu:Uca(cid:173)
`tions cha1u1el, and the wireless intelligent personal server t5
`processes the downstream data to provide at least one
`electronic file. The display device has at least one applica(cid:173)
`tion tbnt nccesses the nt lenst one electronic file to display
`information to a user.
`In a fourth principal aspect, the present invention provides 20
`a method for updating a target electronic file to reHect
`changes made to a source electronic file. In accordance with
`the method, the target electronic file is stored in a wireless
`intelligent personal server. The wireless intelligent personal
`server receives downstream data transmitted over a wireless 25
`communications channel. The downstream data reflects
`changes made to the source electronic file. The wireless

`technology services for a business or other organization. As
`shown in FIG. 1, one or more personal computers, such as
`personal computer (PC) 14. are connected to enterprise IT
`system 12. Enterprise IT system12 may also have access to
`a centralized database for the enterprise, such as enterprise
`database 16. as shown in FJG. l. Enterprise IT system 12
`may be located entirely within one office area, or it may be
`distributed over various remote locations.
`System 10 also includes a first wireless network 20 and a
`to second wireless network 22. First wireless network 20 is
`able to transn:Ut data, at least intennittently, over one or more
`downstream wireless charmels to wireless receivers operat(cid:173)
`ing within its wireless coverage area. Preferably, first wire-
`less network 20 uses subcarriers of frequency modulated
`(FM) radio transmissions and/or televisions transmissions to
`provide the downstream wireless channels. Most preferably,
`the subcarriers used by first wireless network 20 are modu(cid:173)
`lated using orthogonal frequency division multiplexing
`(ODFM) in order to n:Unirnize multipath effects, such as
`fading and distortion, and to increase data throughput.
`Altematively, first wireless network 20 may be a one-way
`paging network, which may use the FLEX rM protocol of
`Motorola, Inc., a two-way paging network, which may use
`the ReFLEX™ protocol of Motorola, Inc., or it may wire(cid:173)
`lessly transmit data by some other means.
`Second wireless network 22 is preferably a cellular or
`PCS network that provides two-way wireless commtmica(cid:173)
`tions, in a fom1at, such a~ AMPS, TDMA, C:DMA, or GSM,
`for wireless telephones, such as wireless telephone 24. Thus,
`with reference to FIG. L wireless telephone 24 is able to
`transmit to wireless network 22 over an upstream channel 26
`and is able to receive from wireless network 22 using a
`downstream channel 27.
`An intermediate network 28 is connected to first wireless
`network 20 and to second wireless network 22, and enter(cid:173)
`prise IT system 12 uses a wireless network management
`system 29 to commtmicate with wireless networks 20 and
`22, via intermediate network 28. lntennediate network 28
`maybe any wide-area network (WAN) or local-area network
`40 (LAN) capable of transmitting digital data between enter(cid:173)
`prise 1T system 12 and wireless networks 20 and 22.
`Preferably. intermediate network 28 is either the Internet or
`a private corporate network.
`A wireless intelligent personal server (WlPS) 30 is able to
`45 receive data wirelessly transn:Utted by first wireless network
`20. When WIPS 30 receives data transn:Utted by wireless
`network 20, WIPS 30 stores it in its memory, as described
`in more detail below. WIPS 30 is able to tmnsfer the data
`stored in its memory to and from di'lferent types of display
`50 devices 32, on at least an intermittent basis. as indicated by
`U1e doned line iu FIG. 1. WJPS 30 may also be able to
`transfer data from its memory to and from wireless tele(cid:173)
`phone 24 on at least an intern:Uttent basis, as indicated by the
`dotted line in FIG. 1.
`Display device 32 is a device that has a user interface for
`displaying U1e data stored in WIPS 30. More particularly,
`display device 32 typically mns one or more applications to
`access Lhe datu stored in
