`
`LEVEL OF ORDINARY SKILL IN THE ART.
`
`10.  
`
`In connection with the preparation of this declaration I have read and
`
`understood 6,038,295 (the “‘295 patent” or the “Mattes patent”) (Ex. 1001);
`
`Google’s Petition for Inter Partes Review; the declaration of Kenneth A. Parulski
`
`(Ex. 1002); Wilska, U.S. Patent 5,613,108 (Ex. 1006); Morikawa, U.S. Patent
`
`6,427,078 (Ex. 1007); the Board’s Decision – Institution of Inter Partes Review,
`
`Paper 21; and Patent Owner’s Response to the Petition.

`
`

`
`11.  
`
`I have been informed that “a person of ordinary skill in the art” is a
`
`hypothetical person to whom an expert in the relevant field could assign a routine
`
`task with reasonable confidence that the task would be successfully carried out. I
`
`have been informed that the level of skill in the art may be evidenced by references
`
`published at or around the time of the filing of the patent under consideration.
`
`Based on my experience, it is my opinion that the level of ordinary skill in the
`
`relevant art at the time of the invention would be a person having a Bachelor of
`
`Science degree in computer science, electrical engineering, or computer
`
`engineering, with approximately 2 years of practical work experience or post-
`
`graduate research in a field such as computer networking and/or distributed
`
`systems. I do not believe the person of ordinary skill in the art would have required
`
`advanced training in digital imaging, however, because the subject Mattes patent
`
`and the cited references are not concerned with any imaging problems or
`
`techniques per se, and instead focus on communicating, storing and administering
`
`digital images transmitted over various communication networks. In June 1996, I
`
`had at least the specified level of experience in the relevant field. Furthermore, at
`
`least by virtue of my teaching computer science classes at the undergraduate and
`
`post-graduate levels, I had and continue to have an understanding of the
`
`capabilities of a person of ordinary skill in the relevant art at the time of the
`
`
`
`

`
`
`
`Google v. TLI Communications
`IPR2014-00283 TLI Ex. 2008
`
`

`
`invention of the ’295 Patent. I have supervised and directed many such persons
`
`over the course of my career.
`
`12.  
`
`I understand that trial has been instituted as to claims 17-24 of the “Mattes
`
`patent, in part, to consider whether claims 17, 19–21, 23, and 24 are unpatentable
`
`under 35 U.S.C. § 103(a) as obvious over the combination of Wilska and
`
`Morikawa. I am advised that even if a claim of a patent may be found unpatentable
`
`if, at the time of the invention, the claim as a whole would have been obvious to a
`
`person of ordinary skill in the art. I understand that considerations of obviousness
`
`involve determining the scope and content of the prior art; ascertaining the
`
`differences between the prior art and the claims at issue; and resolving the level of
`
`ordinary skill in the pertinent art. I further understand that considerations of so-
`
`called secondary indicia of non-obviousness can be important to the obviousness
`
`inquiry, however, I have not been asked to consider any such secondary indicia of
`
`non-obviousness in connection with this declaration.
`
`
`
`III. OVERVIEW OF U.S. PATENT 6,038,295
`
`13.   As I mentioned above, the Mattes patent addresses the problem of
`
`transmitting, storing and classifying digital images that are captured by and issue
`
`
`
`
`5
`
`
`
`Google v. TLI Communications
`IPR2014-00283 TLI Ex. 2008
`
`

`
`from mobile phones.1 The Mattes patent proposes allowing mobile phone users to
`
`prescribe and/or allocate classification information data to such digital images, for
`
`example, by using the phone’s keypad.2 The mobile phone then transmits the
`
`digital images and classification information data to a server. The server extracts
`
`the classification information data and takes it into account when storing the digital
`
`images so that the transmitted images may be “surveyable” and “easily relocated.”3
`
`14.   Claim 17, reads as follows:
`
`A method for recording and
`administering digital images,
`comprising the steps of:
`recording images using a digital
`pick up unit in a telephone unit,
`storing the images recorded by the
`digital pick up unit in a digital form as
`digital images,
`transmitting data including at least
`the digital images and classification
`information to a server, wherein said

`
`
`
`Google v. TLI Communications
`IPR2014-00283 TLI Ex. 2008
`
`

`
`classification information is prescribable by a user of the
`telephone unit for allocation to the digital images,
`receiving the data by the server,
`extracting classification information which characterizes the
`digital images from the received data, and
`storing the digital images in the server, said step of storing
`taking into consideration the classification information.
`
`
`
`IV. CLAIM CONSTRUCTION
`
`15.  
`
`I understand that the Board has initially determined that the “classification
`
`information” recited in claim 17 should be construed as “information that
`
`characterizes or is otherwise associated with a digital image.”4 I have applied this
`
`construction in my analysis below.
`
`16.  
`
`I am advised that in proceedings before the USPTO, the Board accords the
`
`claims of an unexpired patent their broadest reasonable interpretation in view of
`
`the specification from the perspective of one of ordinary skill in the art. I have
`
`been informed that the Mattes patent has not expired. Therefore, in considering the
`
`matters discussed herein I have given the claims their broadest reasonable

`
`interpretation in view of the specification from the perspective of one of ordinary
`
`skill in the art.
`
`
`
`V. COMPARISON OF WILSKA AND MORIKAWA WITH
`
`CLAIM 17 OF THE MATTES PATENT
`
`17.  
`
`I have been asked to consider whether, to a person of ordinary skill in the
`
`art, claim 17 of the Mattes patent would be obvious in view of the combined
`
`teachings of Wilska and Morikawa. In my opinion, claim 17 would not have been
`
`obvious in view of these references. I provide the reasoning behind my opinion in
`
`this regard below.
`
`18.   Wilska describes a “notebook computer” (illustrated schematically in Fig 3,
`
`reproduced below) that includes “a radiotelephone, i.e., a cellular mobile phone
`
`unit 17, . . . connected to [a] cellular mobile phone controller 8.”5 “Both data and
`
`speech can be transmitted via integrated cellular mobile phone unit 17.”6 The
`
`camera of the notebook computer “functions to record images and paper
`
`documents.”7 According to Wilska, image information recorded by the camera is
`
`
`5 Ex. 1006 at 3:36-39
`
`6 Id. at 3:44-47.
`
`7 Id. at 3:63.

`
`

`
`“scanned in” to memory of the notebook computer,8 after which a user can process
`
`the data according to his or her purposes using an application program.9
`
`
`
`Thus, Wilska describes the camera as a “data collection” device,10 which is used to
`
`input information into the notebook computer.
`
`19.  
`
`In one example, Wilska describes inputting “information included in
`
`business cards” into the notebook computer’s memory.11 Here, the output of the
`
`camera (e.g., a picture of a business card) is transferred to the notebook computer,
`
`where the user can use a business card handler application to select suitable fields

`
`

`
`from the business card, and drop the associated information from those fields into
`
`an address directory.12
`
`20.  
`
`In other examples, Wilska explains that graphical or character recognition
`
`software can attempt to automatically collect information from pictures of hand
`
`written notes.13 Or, the information scanned in from the camera can be stored in the
`
`memory of the notebook computer as a bitmap.14 A bitmap is used because, “This
`
`type of image information is used in facsimile/telefax transmission.”15
`
`21.   A separate embodiment discussed by Wilska concerns an optional digitizer
`
`pad 29 that can be replaceably installed in the notebook computer.16
`
`
`
`The digitizer pad 29 allows a user to write text or draw figures on the viewing
`
`screen 29a using pen 33.17 The digitizer pad 29 recognizes the touch of pen 33 and

`
`
`10
`
`
`
`Google v. TLI Communications

`
`

`
`converts the perceived path of the pen 33, as it touches the digitizer pad 29, into a
`
`bitmap.18
`
`22.  
`
`In connection with the digitizer pad embodiment, Wilska states that, “[a] text
`
`of figure written or drawn on digitizer pad 29 of notebook computer 27 can be
`
`stored later as an image in memory unit 13 of the notebook computer or fed to the
`
`character/object recognition software for further processing.”19 This allows
`
`handwritten text to be converted to ASCII text in the same way as is done for the
`
`camera, for example.20 “The bitmap images or converted ASCII text/graphics
`
`transferred to the memory from digitizer pad 29 of notebook computer 27 can be
`
`later forwarded via telefax or electronic email services . . . .”21 “When transmitting
`
`electronic mail or telefax messages, the user can digitize the message on the

`

`

`
`21 Id. at 7:36-40. Wilska states that “The bitmap images or converted ASCII
`
`text/graphics . . . can be later forwarded via telefax or electronic email services, as
`
`disclosed above in the description of the invention,” id. (emphasis added),
`
`however, the only disclosure provided above in the patent is telefax transmission of
`
`a bitmap at 6:3-6. There is no earlier discussion of emailing a bitmap.
`
`
`
`

`
`

`
`display of the notebook computer and to [sic] simply select the recipient
`
`information from the phone list.”22
`
`23.   Considering the explanation provided by Wilska as a whole, there is nothing
`
`that teaches or suggests using email attachments of any kind, let alone attachments
`
`that comprise digital images. Instead, Wilska contemplates the transmission of
`
`bitmaps using telefax.23 Email services are reserved for converted ASCII
`
`text/graphics, or digitized messages on the display of the notebook computer.24
`
`24.   This limitation concerning the use of email is not surprising. In or about
`
`May 1995, which I understand to be the earliest filing date of Wilska, and
`
`continuing to at or about the time of the invention of the Mattes patent,
`
`experimental prototypes that facilitated the use of email with multimedia
`
`extensions in a mobile computing environment were just in their initial stages of
`
`development.25 The developers of such prototypes noted concerns with issues such
`
`as available bandwidth, variable network communication quality, and costs of
`
`transmission.26

`
`Google v. TLI Communications
`IPR2014-00283 TLI Ex. 2008
`
`

`
`25.   Further, as late as 1994, researchers reported that despite nearly a decade’s
`
`worth of investigation within the area of multimedia email, “To our knowledge, the
`
`integration of a multimedia database system with multimedia electronic mail for
`
`the realization of a multimedia archiving teleservice is a new approach not reported
`
`in any previous work.”27 Solutions available at that time were said to be “very
`
`restrictive.”28 A prototype system then under development was having to integrate
`
`newly defined email extension mechanisms to accommodate “externally-defined
`
`bodypart types.”29 Even then, however, because of restrictions on the size of emails
`
`that could be accommodated by network nodes located between a sender and a
`
`recipient, the multimedia data could not be included as part of an email message
`
`itself, but rather had to be stored in a remotely accessible database and designated
`
`by reference in the body of the email message, as shown in the following
`
`illustration.30

`
`Google v. TLI Communications
`IPR2014-00283 TLI Ex. 2008
`
`

`
`
`
`Thus, at the relevant time period the use of email for multimedia attachments such
`
`as images was not a common practice and faced many challenges.
`
`26.   Morikawa, on the other hand, provides no teachings for organizing images
`
`that are not email attachments. More specifically, Morikawa describes an
`
`electronic mail processing system (shown in Fig 1, reproduced below) in which a
`
`mail message M is stored to a mailbox MB and then later transferred to a user mail
`
`server.31 At the user mail server, a heading file HF of the of the mail M is stored to
`
`aa message folder FM while an attachment file AF is stored in a shared folder F0.32
`
`Once the attachment file AF has been stored in the shared folder F0, a file analysis
`
`process is run and a “folder suited for the attachment file AF is set.”33 Thereafter,
`
`
`31 Ex. 1007 at 6:1-7.
`
`32 Id. at 8:3-6.
`
`33 Id. at 8:7-9.
`
`
`
`
`14
`
`
`
`Google v. TLI Communications
`IPR2014-00283 TLI Ex. 2008
`
`

`
`the attachment file AF is transferred from the shared folder F0 to the set folder (F1,
`
`F2, F3, or a new folder).34
`
`
`
`27.   Morikawa describes different ways that the file analysis process may
`
`establish the set folder into which the attachment file AF is transferred. If a specific
`
`folder is identified in a data directory D12 of mail M’s so-called envelope part
`
`(illustrated in Fig. 2, reproduced below), then the attachment file AF will be
`
`transferred to that folder if it exists.35 If the specified folder does not exist, but a
`
`request for creating a new folder is included in mail M’s envelope part, then the
`

`
`
`
`15
`
`
`
`Google v. TLI Communications
`IPR2014-00283 TLI Ex. 2008
`
`

`
`new folder will be created and the attachment file AF transferred thereto.36
`
`
`
`If no specific folder is identified in mail M’s envelope part, then file attribute
`
`information is extracted from the attachment file AF, and used to determine which
`
`folder the attachment file is transferred to. 37 The file attribute information is made
`
`up of ASCII characters or specific extensions specified by application software at
`
`the transmitting side of the mail exchange.38
`
`28.  
`
`In my opinion, a person of ordinary skill in the art would not combine
`
`Morikawa’s email attachment organization approach with the teachings of Wilska.

`
`

`
`As I noted above, Wilska does not teach or suggest the use of email attachments.
`
`Further, as late as 1994, and despite nearly a decade’s worth of research in the area
`
`of multimedia email, Thimm et al. reported that their proposed integration of a
`
`multimedia database system with multimedia electronic mail for the realization of
`
`a multimedia archiving teleservice was the first of its kind,39 and even that solution
`
`did not contemplate the use of multimedia attachments as Petitioner’s proposed
`
`combination of Wilska and Morikawa would require. I note that Petitioner does not
`
`discuss the difficulties that would be encountered by a person of ordinary skill in
`
`the art seeking to implement a system such as is proposed, yet Thimm et al.
`
`indicate that at the relevant time period nodes of a network that would be tasked
`
`with handling such emails may have been incapable of doing so.40 Such
`
`considerations, along with concerns regarding network communication quality and
`
`costs of transmission, would suggest to the person of ordinary skill in the art that
`
`other approaches be followed.
`
`29.   Further, even if a person of ordinary skill in the art did combine the
`
`teachings of Wilska and Morikawa, the result of that combination would be
`
`something different than the subject matter recited in claim 17. For example, the
`
`
`39 Ex. 2007 at 2.
`
`40 Id. at 4.
`
`
`
`
`17
`
`
`
`Google v. TLI Communications
`IPR2014-00283 TLI Ex. 2008
`
`

`
`resulting combination would include Wilska’s hand-held device in which a camera
`
`is used to collect data in the form of bitmap images that are transmitted via telefax,
`
`not email.41
`
`30.   Alternatively, even if for sake of argument, Wilska describes transmitting
`
`bitmap images via email services, Wilska fails to describe the format or
`
`arrangement of the email messages. Morikawa describes email messages that
`
`include an envelope part and a content part.42 The envelope part would include
`
`various control information, as identified in Fig. 2, above,43 and the content part,
`
`which consists of a heading file HF (the message) and attachment files AF, would
`
`include the information to be transmitted,44 which, according to Petitioner (but not
`
`Wilska or Morikawa), would be the bitmap image. As indicated above, the use of
`
`such email attachments was only in an experimental stage at best, and researchers
`
`reported that the network infrastructure required to support such use did not exist.
`
`31.  
`
`It is therefore entirely reasonable to conclude that, even if the combination
`
`of Wilska and Morikawa can be read as providing for transmitting bitmap images
`
`
`41 Ex. 1006 at 7:37-41, 54-57.

`
`

`
`captured by the camera of Wilska’s hand-held device using electronic mail
`
`services, the combination does not teach including the bitmap images as
`
`attachments to those emails. Consequently, none of Morikawa’s description
`
`concerning the processing of attachments would apply and, accordingly, none of
`
`the “extracting,” or “storing” elements of claim 17 would be present in the
`
`combined teachings of the references.
`
`32.   Finally, even if bitmap images were included as attachments to emails
`
`transmitted by Wilska’s hand-held device, then one would expect those
`
`attachments to be processed as provided for by Morikawa. According to
`
`Morikawa, the only information that is “extracted” during such processing is the
`
`file attribute information that describes the attachment file, AF.45 Therefore, in the
`
`Wilska-Morikawa combination, at best, it is the file attribute information that is
`
`extracted.
`
`33.   The file attribute information is not, however, “classification information [ ]
`
`prescribable by a user of the telephone unit for allocation to the digital images,”46
`
`as required by claim 17. Instead, the file attribute information is type-of-file
`
`information, classified in accordance with the application software used to create

`
`

`
`the file, or, in the special case of a text document, the ASCII code representing the
`
`first character of that document.47 In each case, rather than being specified by a
`
`user of the Wilska hand-held device, the file attribute information would be created
`
`by or in accordance with the application software that is used to generate the file
`
`itself.
`
`34.   The system-specified file attribute is the only information that Morikawa
`
`describes as being “extracted” during processing of an attachment file, AF.48 For
`
`example, Morikawa indicates that, “the [server] may include a folder selection unit
`
