`
`Sir:
`
`The Requestor, Rosetta-Wireless Corporation (hereinafter “Rosetta”), the owner of U.S.
`
`Patent No. 7,149,511 (attached as Exhibit A) (hereinafter the “‘511 patent”), which issued on
`
`December 12, 2006 to Bachner, III et a1., requests ex parte re-examination of the ‘511 patent
`
`under 35 U.S.C. §§ 302-307 and 37 CFR §§ 1.501-1.570 (hereinafter the “Request”). Since
`
`the issuance of the ‘ 511 patent, a third party (hereinafter the “Third Party”) has identified
`
`various printed publications it considers relevant to claims of the ‘511 patent. These printed
`
`publications were not cited during the prosecution of the application that issued as the ‘511
`
`patent. The Third Party has asserted a belief that at least some of the printed publications
`
`raise a substantial new question of patentability. Rosetta files this Request to resolve any
`
`substantial new question of patentability raised by specific printed publications identified
`
`herein.
`
`For the Commissioner’s convenience, the following is a brief overview of the contents
`
`of this Request. Section I of this Request identifies the printed publications that were not
`
`cited during the prosecution of the application that issued the ‘511 patent and which are being
`
`

`
`submitted for consideration in the event that the Commissioner believes that a substantial new
`
`question of patentability exists. Section II identifies the claims for which re-examination is
`
`requested. Section III is a statement pointing out each substantial new question of
`
`patentability. Section IV provides a detailed explanation of the alleged pertinency and
`
`manner of applying printed publications to claims 1 and 58 of the ‘511 patent. Section V
`
`provides the proposed rejection for claims 1 and 58 for which reexamination is requested.

`
`II.
`
`IDENTIFICATION OF CLAIMS FOR WHICH RE-EXAMINATION IS REQUESTED
`
`In accordance with 37 CFR 1.510, re-examination is requested for claims 1 and 58 of
`
`U.S. Patent No. 7,149,511 (“the ‘S11 patent”), which is entitled “Wireless Intelligent Personal
`
`Server.” Specifically, re-examination of claims 1 and 58 of the ‘S11 patent is requested.
`
`III.
`
`STATEMENT POINTING OUT EACH SUBSTANTIAL NEW QUESTION OF
`
`PATENTABILITY
`
`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
`
`

`
`examination of the patent under reexamination.
`
`A new question of patentability as to claims 1 and 58 is raised by Exhibit 1, 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 detennining
`
`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 ‘S11 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.‘
`
`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 9110i 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 ’5l1 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’).
`
`4
`
`

`
`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 of the ‘S11 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 ‘S11 patent proceeding on the merits.
`
`V.
`
`PROPOSED REJECTIONS
`
`The proposed rejections for claims 1 and 58 for which reexamination is requested are
`
`as follows:
`
`0 Claims 1 and 58 appear to be unpatentable over Exhibits C and D in view of
`
`Exhibit F.
`
`0 Claims 1 and 58 appear to be unpatentable over Exhibits C and D in view of
`
`Exhibit G.
`
`0 Claims 1 and 58 appear to be unpatentable over Exhibits C and H in View of
`
`Exhibit D.
`
`0 Claims 1 and 58 appear to be unpatentable over Exhibits C and D in view of
`
`Exhibit 1.
`
`

`
`0 Claims 1 and 58 appear to be unpatentable over Exhibits C and D in view of
`
`Exhibit E.
`
`VI.
`
`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-
`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
`interface for a wireless telephone. The RF receiver receives
`downstream data transmitted over a downstream wireless
`communications channel. The CPU executes the machine
`
`language instructions to process the downstream data and,
`thereby, either update an 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-
`tronic files stored in the memory. The wireless intelligent
`personal server may also transmit an upstream signal over an
`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 data
`reflecting changes to the electronic files stored in the
`memory made by the display device.

`electronic file stored in a source computer.
`B. Description of Related Art
`A typical modern office uses a number of different data-
`bases of information 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 either an ofiice—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 run applications that retrieve
`the desired information from the databases and display it to
`the user. With this configuration, the most up-to-date ver-
`sions of the databases are typically available to the indi-
`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, and, typically, it is
`more difficult to gain access to the most up-to-date versions
`of important electronic files when outside of the office
`environment. A currently used solution is to use portable
`computers to “dial in” to the office network using the PSTN,
`Internet, or other wireline networks. However, mobile work-
`ers do not always have access to wireline connections at all
`desired times. Accordingly, wireless communications sys-
`tems have been developed by which mobile workers can
`access their ofi‘ice databases even without a wireline con-
`
`nection. As an example, some wireless telephones are able
`to send and receive limited amounts of data using the
`wireless application protocol (WAP).
`communications
`However, most of
`these wireless
`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-
`mation. In particular, there is the time spent entering the
`keystrokes needed to make the request, the 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-
`mitting the response through the intermediate networks and
`then over the air interface. The high latency is not only
`troublesome to the user; it leads to high costs due to the
`airtime needed to process the request and the response.
`The problem becomes more acute the more interactive the
`transaction becomes. A user using WAP to retrieve a new
`e-mail message with an attachment provides a simple illus-
`tration of the problem. First, the user requests the new e-mail
`message a11d receives it after waiti11g for the late11cy period
`described above, for which the user is typically charged
`airtime. Second, the user reads the new e-mail message and
`sees that it has an attachment. Then the user must make

`
`another request to receive the attachment. The user waits for
`another latency period to receive it, thereby typically incur-
`ring additional airtime charges. Moreover, the latency period
`may be quite long, because files attached to e-mails are often
`quite large. Accordingly, existing “pull” approaches, such as
`WAP have substantial disadvantages.
`Another problem with many technologies for receiving
`data over wireless channels is that they are highly device-
`specific, i.e., they are based on providing wireless function-
`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 of the user’s computing devices with
`wireless functionality is, at best, only a partial solution.
`Second, dilferent computing devices dilfer in their abilities
`to handle different types of data. For example, desktop PCs
`typically have much more memory than PDAs, and desktop
`PCs often have access to high quality monitors, speakers,
`and peripherals to display information and provide function-
`ality to the user in ways that are unavailable to typical PDAs.
`On the other hand, PDAs also have many advantages over
`a desktop PC, such as portability. In addition to the avail-
`ability of different hardware, dilferent computing devices
`may have different operating systems and applications avail-
`able to them. Accordingly, approaches that provide wireless
`functionality only to specific devices have substantial dis-
`advantages.
`For example, Kaufman, U.S. Pat. No. 6,034,621, dis-
`closes systems and methods for communicating changes
`made to a data file 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, synchronization information is transmitted over a
`paging network to a pager that is connected to the PDA, such
`as by a serial or parallel connection. A synchronization
`routine in the PDA then interacts with the synchronization
`information output from the pager to update the data file in
`the PDA.
`
`While potentially reducing the latency problem, at least
`for small amounts of data, the Kaufman approach suffers
`from a number of disadvantages. First, PDAs are not typi-
`cally on all of the time. Thus, update information may be
`missed because of the PDA being off. Second, PDAs typi-
`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 of the very large electronic files that they
`can access at their offices.
`
`SUMMARY OF THE INVENTION
`
`In a first principal aspect, the present invention provides
`a wireless intelligent personal server that comprises a radio
`frequency (RF) receiver for receiving downstream data
`transmitted over a wireless communications charmel, a
`memory, a central processing unit (CPU), a set of embedded
`machine language instructions that are executable by the
`CPU for processing the downstream data to provide at least
`one electronic file in the memory, and a first interface for
`allowing an external display device to access the at least one
`electronic file.
`
`In a second principal aspect, the present invention pro-
`vides a wireless data communication system that comprises
`a wireless intelligent personal server a11d a wireless tele-
`phone in communication with the wireless intelligent per-
`sonal
`server. The wireless
`intelligent personal
`server
`includes a memory and a radio frequency (RF) receiver. The

`RF receiver receives downstream data transmitted over a
`first wireless communications charmel, and the wireless
`intelligent personal server processes the downstream data to
`provide at
`least one electronic file in the memory. The
`wireless telephone transmits an acknowledgement over a
`second wireless communications charmel when the wireless
`
`intelligent personal server receives the downstream data.
`In a third principal aspect, the present invention provides
`a wireless data display system that comprises a wireless
`intelligent personal server and a display device in commu-
`nication with the wireless intelligent personal server. The
`wireless intelligent personal server includes a memory and
`a radio frequency (RF) receiver. The RF receiver receives
`downstream data transmitted over a wireless communica-
`
`tions charmel, and the wireless intelligent personal server
`processes the downstream data to provide at
`least one
`electronic file. The display device has at least one applica-
`tion that accesses the at least one electronic file to display
`information to a user.
`
`In a fourth principal aspect, the present invention provides
`a method for updating a target electronic file to refiect
`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
`communications charmel. The downstream data reflects
`
`changes made to the source electronic file. The wireless
`intelligent personal server automatically updates the target
`electronic file with the downstream data to provide an
`updated electronic file. A display device is brought into
`communication with the wireless intelligent personal server,
`and the display device accesses the updated electronic file.
`In a fifth principal aspect, the present invention provides
`a method for creating, without user intervention, an elec-
`tronic file on a wireless intelligent personal server.
`In
`accordance with the method, the wireless intelligent per-
`sonal server receives downstream data transmitted over a
`wireless communications charmel. The wireless intelligent
`personal server automatically creates the electronic file from
`the downstream data. A display device is brought
`into
`communication with the wireless intelligent personal server,
`and the display device accesses the electronic file.

`
`DETAILED DESCRIPTION OF THE
`INVENTION
`
`FIG. 1 is a functional block diagram of a wireless com-
`munication system 10 in accordance with an exemplary
`embodiment of the present invention. System 10 includes a11
`enterprise information technology (IT) system 12, which
`typically includes a plurality of computers and other devices
`networked together to provide computing and information
`
`4
`
`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 system 12 may also have access to
`a centralized database for the enterprise, such as enterprise
`database 16, as shown in FIG. 1. Enterprise IT system 12
`may be located entirely within one office area, or it may be
`distributed over various remote locations.
`
`10
`
`System 10 also includes a first wireless network 20 and a
`second wireless network 22. First wireless network 20 is
`
`able to transmit data, at least intermittently, over one or more
`downstream wireless charmels to wireless receivers operat-
`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-
`lated using orthogonal
`frequency division multiplexing
`(ODFM) in order to minimize multipath elfects, such as
`fading and distortion, and to increase data throughput.
`Alternatively, first wireless network 20 may be a one-way
`paging network, which may use the FLEXTM protocol of
`Motorola, Inc., a two-way paging network, which may use
`the ReFLEXTM protocol of Motorola, Inc., or it may wire-
`lessly transmit data by some other means.
`Second wireless network 22 is preferably a cellular or
`PCS network that provides two-way wireless communica-
`tions, in a format, such as AMPS, TDMA, CDMA, or GSM,
`for wireless telephones, such as wireless telephone 24. Thus,
`with reference to FIG. 1, wireless telephone 24 is able to
`transmit to wireless network 22 over an upstream charmel 26
`and is able to receive from wireless network 22 using a
`downstream charmel 27.
`An intermediate network 28 is connected to first wireless
`network 20 and to second wireless network 22, and enter-
`prise IT system 12 uses a wireless network management
`system 29 to communicate with wireless networks 20 and
`22, via intermediate network 28. Intermediate network 28
`maybe any wide-area network (WAN) or local-area network
`(LAN) capable of transmitting digital data between enter-
`prise IT 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 (WIPS) 30 is able to
`receive data wirelessly transmitted by first wireless network
`20. When WIPS 30 receives data transmitted by wireless
`network 20, WIPS 30 stores it in its memory, as described
`in more detail below. WIPS 30 is able to transfer the data
`stored in its memory to and from different types of display
`devices 32, on at least an intermittent basis, as indicated by
`the dotted line in FIG. 1. WIPS 30 may also be able to
`transfer data from its memory to and from wireless tele-
`phone 24 on at least an intermittent basis, as indicated by the
`dotted line in FIG. 1.
`
`Display device 32 is a device that has a user interface for
`displaying the data stored in WIPS 30. More particularly,
`display device 32 typically runs one or more applications to
`access the data stored in WIPS 30 and to display it to the
`user. The applications on display device 32 may also allow
`the user to modify the data stored in WIPS 30. Display
`device 32 may be a fixed-mounted device, such as a desktop
`PC, an advanced video game device, such as a Sony “Play-
`Station 2” device, or a set-top television controller box, such
`as the type used to access services such as WebTV© (a11d
`which may also provide game-type functionality), or display
`device 32 may be a portable device, such as a laptop PC or
`a personal digital assistant (PDA). Moreover, WIPS 30

`preferably allows different kinds of display device 32 to
`access the data stored on it at different times. For example,
`a user may use a first desktop PC as display device 32 to
`access the data stored in WIPS 30 at work, may use a PDA
`as display device 32 to access the data stored in WIPS 30
