`
`I.
`
`BriefSummary of Wang
`
`Wang is directed to methods and apparatuses for transferring digital information on a network. One
`
`of the methods is for enabling a client to upload an album of images to a server. Another method is for
`
`enabling a client to download an album of images from a server. Each of these is explained below.
`
`The method described with reference to FIGS. 4A and 4B ofWang is for enabling a client to upload
`
`an album ofimages onto a server. [1] Such uploading ofan album from the client onto the server is initiated
`
`by the client sending a post command to the server (see Wang, column 5, lines 35-40). In response to
`receiving the post command from the client, the server examines its database to determine whether the album
`
`already exists (see Wang, column 5, lines 63 -65). [2] Ifthe album already exists in the server’s database, the
`
`server sends a query to the client asking the user ofthe client whether the user wants to replace the existing
`
`album on the server’s database. [3] If the user selects the option ofreplacing the existing album, the client
`
`sends “album envelope data” to the server (see Wang, column 5, line 65 — column 6, line 2). The “album
`envelope data” specifies the title ofthe album, the number ofimages in the album, the layout ofthe album,
`
`the background ofthe album and a “signature list” for the images in the album (see Wang, column 6, lines 2-
`
`6). The “signature list” includes a signature for each image in the album, which can be a 16-32 byte
`
`Attorney Docket No.: SYMA-01042USO
`JKurin/SYMA/1042USOOARespwpd
`
`- 3 _
`
`fl
`
`Oracle Exhibit 1002, pg 8
`
`Oracle Exhibit 1002, pg 8
`
`

`

`' identification code uniquely identifying eachimage (seeWang, column 6, lines 6-9). Once the server receives
`the “signature list” from the client, the server determines which images are matched (i.e., already exist on
`the server) and which images are not matched (i.e., do not already exist on the server) (see Wang, column
`6, lines 10-15). [4] A list ofthe matching signatures is then sent from the server to the client (see Wang,
`column 6, lines 15—17). [5] The client then sends to the server the entire images that are not on the list of
`matching signatures, and transformation information for1mages that were onthe list ofmatchmg signatures
`(see Wang, column 6, lines 17-29). The serveruses this informationreceived from the client to update the
`album.
`
`Accordingly, Wang’5 method[explained inFIGS, 4A and 4B is for aprotocol thatrequires multiple
`communications between the client and the server, in order for the client to replace or update an album
`already existing on the server. More specifically, five separate and distinct communications between the
`client and the server are required to update an album using the method of Wang. Each of these five
`communications is labeled above by a bolded bracketed number (i.e., [#1).
`h
`The method described with reference to FIGS. 5A and 5B of Wang is for enabling a client to
`download an album ofimages from a server. [1] Such downloading ofan album to a client from a server is
`initiated by the client sending a GET command to the server, and the client specifying the album to be
`retrieved(seeWang, column7,lines23-34). [2] Inresponse,the serverretrievesthe appropriatealbumfrom
`itsdatabase, and sends the clientthe albumenvelope dataforthe album, includinga signature list(seeWang,
`column7, lines 34-36). Onthe client,the signaturelist'isreceived fromthe serverandexaminedto determine
`whichimages arenotstoredlocallyonthe clientcomputer. [3] The clientthenretrieves (i.e., requests) from
`the server images that donotmatch (see Wang, column7, lines 39—41). [4] The server retrieves the images
`from its database and sends the images over to the client (see Wang, column 7, lines 43—44).
`Accordingly, Wang’s methodexplained1nFIGS 5A and 5B15 foraprotocolthatrequiresmultiple
`communications between the client and the server, in order for the client to replace or update an album
`already existingonthe client. More specifically, four separate anddistinctcommunicationsbetweenthe client
`the server are required to download an album from a server to a clientusing the method ofWang. Each of
`these four communications is labeled above by a bolded bracketed number Ge, [#1).

`
`BriefSummary ofApplicant’s Claimed Invention
`
`In contrast, Applicant’s invention provides “a mechanism by which a user can be automatically
`
`provided with a current version ofa file towhich he subscribes.” (See Applicant’s specification, page 5, lines
`4-5.) An object ofthe invention is to “communicate the current version of the file in an efficient manner.
`
`According to the present invention, a server computer monitors network files and folders stored on the
`
`network for changes and
`
`generates an update file for transmission to a client computer that permits the
`
`client computer to generate a copy ofa current version ofa subscription file from a copy ofan earlier version
`
`of the subscription file.” (See Applicant’s specification, page 5, lines 7-12.) In other words, Applicant’s
`
`~invention provides a method by which a server generates an update file that is automatically sent to a client
`
`V (when the server detects a change in a file that the server monitors). The update file permits the client
`
`receiving the update file to use the update file along with its stored earlier version ofthe subscription file to
`
`generate the current (i.e., latest) version ofthe subscription file. This is a very efficient manner for enabling
`a client to update its files.
`
`In Applicant’s invention, the client computer informs the server computer ofwhich files and folders
`
`it wants to subscribe to, i.e., which files it wants the server computer to monitor for changes. The server
`
`computer then acts as an “electronic assistant” by tracking files (e.g., documents) and folders (see
`
`Applicant’s specification, page 10, line 24- page 11, line 4). The actual monitoring for changes and the
`
`generation ofan update file, in response to detecting a change, are performed by the server computer without
`interaction from the client computer. Claim 1 has been amended to make clear this distinction. Claim 1 as
`
`amended is shown below for the convenience ofthe Examiner, with the amended language being underlined.

`
`BriefSummary ofDijflrences between Applicant’s Claimed Invention and Wang
`
`As explained in detail above, Wang provides a method for enabling a client to upload an album of
`images to a server, and a method for enabling a client to download an album to images from a server. Each
`ofthese methods ofWang is initiatedbythe client and requires multiple interactions between the client and
`the server, as explained above.
`
`In contrast, Applicant’s claimed invention enables a server computer to monitor network files and
`folders stored on a network for changes and to generate an update file for transmission to a client computer,
`wherein the update file permits the client computer to generate a copy ofa current version ofa subscription
`file from a copy ofan earlier version ofthe subscription file. As explained above, and as specified in the
`claims as amended, the steps for generating the update file “are performed by the server computer, without
`interaction with the client computer, in response to the server computer detecting a change between the
`
`current version of the subscription file and the earlier version of the subscription file.”
`
`IV.
`
`Discussion of Claims
`
`A. Claims 1 and 4-10
`
`Independent claim 1, as amended, specifies that steps (a) through (c) of the method for a server
`computerto generate an update file “are performedby the server computer, without interaction with the client
`computer, in response to the server computer detecting a change between the current version of the
`subscription file andthe earlier versionofthe subscription file.” Accordingly, claim 1 describes a method by
`which a user can be automatically provided with a current version of a file to which he subscribes.
`In
`
`contrast, the methods ofWang are initiatedby the client and require multiple interactions between the client

`
`Oracle Exhibit 1002, pg 11
`
`

`

`and the computer, as explained in detail above. For at least this reason, Applicants assert that the method of
`
`claim 1 is clearly different than the methods taught in Wang. Accordingly, Applicant respectfully requests
`
`that the 35 U.S.C. §102(e) rejection of claim 1 be withdrawn.
`
`Claims 4-10 depend from and add additional features to claim 1 . For at least the reasons discussed
`
`above, Applicants assert that these claims are patentable over the applied references. Accordingly,
`
`'Applicants respectfully request that the 35 U.S.C. § 103(a) rejection of these claims be withdrawn.
`
`Applicants also assert that these dependent claims are patentable for the specific features they add,
`some of which are discussed below.
`
`Dependent claim 7 adds the step of “transmitting the update file to the client computer as an
`
`executable attachmentby electronic mail, wherein the executable attachment will cause the client computer
`to generate a copy ofthe current version ofthe subscription file from the copy ofthe earlier version ofthe
`subscription file, in response to the client computer executing the attachment." It was alleged in the Office
`
`Action that Freivald teaches transmitting an update file to the client computer as an executable attachment
`
`by electronic mail (see Office Action, item 14, pages 6-7). However, Freivald merely teaches notifying the
`
`user, by electronic email, when a change to a web-page is detected, possibly along with a copy ofthe entire
`
`new file so that the user can review the changes (see Freivald, column 6, lines 22-25). Freidvald’s sending
`
`a copy ofthe entire new file is quite different and much less efficient than Applicant’s sending an update file
`
`as an executable attachment that will cause the client to generate a current version from a previous version
`
`ofa file, as required by claim 7. For this additional reason, Applicant respectfully requests that the 3 5 U.S.C.
`§ 103(a) rejection of claim 7 be withdrawrr.
`
`Claims 11 and 14-20
`‘ B.
`Independent claim 1] is directed to a computer readable storage medium comprising a computer
`
`readable program cede for programing a computer to perform a method that includes steps substantially the
`
`same as those of the method of claim 1. Accordingly, Applicant asserts that claim 1 1, and its dependent
`
`claims 14-20, are patentable for at least the same reasons discussed above with respect to claims 1 and 4-10.
`
`Applicant respectfully requests that the rejection of these claims be withdrawn.

`
`Claims 21 and 24-30
`
`Independent claim 21 is directed to a computer system comprising a processor and a processor
`
`readable storage medium having processor readable program code for programing a computer to perform a
`
`method that includes steps substantiallyithe same as the steps of the method of claim 1. Accordingly,
`
`Applicant asserts that claim 21, and its dependent claims 24-30, are patentable for at least the same reasons
`
`discussed above with respect to claims 1 and 4-10. Applicant respectfully request that the rejection ofthese
`claims be withdrawn.

`APPENDIX
`
`In the Claims:
`
`1.
`
`(Twice Amended) A method for a server computer to generate an update file for transmission to
`
`a client computer that permits the client computer to generate a copy of a current version of a
`
`subscription file comprised of a first plurality of file segments from a copy of an earlier version of the
`
`subscription file comprised of a second plurality of file segments, such that each file segment corresponds
`
`to a portion of its respective subscription file, the method comprising the steps of:
`
`for each segment of the current version of the subscription file,
`
`(a)
`
`(b)
`
`. searching an earlier version of a signature list corresponding to an earlier version
`of the subscription file for an old segment signature which matches a new
`
`segment signature corresponding to the segment;
`
`if step (a) results in a match, writing a command in the update file for the client
`computer to copy an old segment of the client computer’s copy of the earlier
`version of the subscription file into the client computer’s copy of the current
`version of the subscription file, wherein the old segment corresponds to the
`
`,
`é
`
`segment for which a match was detected in step (a); and
`
`(c)
`
`if step (a) results in no match, writing a command in the update file for the client
`
`computer to insert a new segment of the current version of the subscription file
`
`into the client computer’s copy of the current version of the subscription file;
`
`wherein the new segment of the current version of the subscription file is written into the
`
`update file and the unchanged segment is excluded from the update file; and
`
`whg'ejr_r steps (a) through to) are performed by the server computer, without interaction
`
`with the client computer, in resmnse to the server computer detecting a change between
`
`the current version of the subscription file and the earlier version of the subscription file.
`
`7.
`
`(Twice Amended) A method as in claim 1, further comprising the step of:
`
`(d)
`
`transmitting the update file to the client computer as an executable attachment by
`
`electronic mail, wherein the executable attachment will cause the client computer to generate a copy of

`
`11.
`
`(Twice Amended) A computer readable storage medium, comprising:
`
`computer readable program code embodied on said computer readable storage medium, said
`
`computer readable program code for programming a computer to perform a method for a server
`
`computer to generate an update file for transmission to a client computer that permits the client computer
`
`to generate a copy of a current version of a subscription file comprised of a first plurality of file segments
`
`from a copy of an earlier version of the subscription file comprised of a second plurality of file segments,
`
`such that each file segment corresponds to a portion of its respective subscription file, the method
`comprising the steps of:
`
`for each segment of the current version of the subscription file,
`
`-
`
`(a)
`
`searching an earlier version of a signature list corresponding to an earlier version
`of the subscription file for an old segment signature which matches a new
`
`segment signature corresponding to the segment;
`
`(b)
`
`if step (3) results in a match, writing a command in the update file for the client
`
`computer to copy an old segment of the client computer’s copy of the earlier
`
`version of the subscription file into the client computer’s copy of the current
`
`version of the subscription file, wherein the old segment corresponds to the
`
`segment for which a match was detected in step (a); and
`
`(c)
`
`if step (a) results in no match, writing a command in the update file for the client
`computer to insert a new segment of the current version of the subscription file
`into the client computer’s copy of the current version of the subscription file;
`
`wherein the new segment of the current version of the subscription file is written into the
`
`update file and the unchanged segment is excluded from the update file; and
`
`wherein stpps 1a) through (c) are performed by the server computer, without interaction
`
`with the client computer, in respo
