`
`
`
`I, Rajeev Surati, Ph.D., of Cambridge, Massachusetts, declare that:
`
`I.
`
`INTRODUCTION AND SCOPE OF WORK
`
`1.
`
`I have been retained by Patent Owner BlackBerry Limited in the
`
`above-captioned Inter Partes Review (IPR) as an independent expert in the
`
`relevant field.
`
`2.
`
`I have been asked to provide my independent analysis regarding the
`
`references identified by petitioner Facebook, Inc., Instagram, LLC, WhatsApp Inc.
`
`(“Petitioner”) in this IPR related to U.S. Patent 8,209,634 (“the ’634 patent”),
`
`which is assigned to Patent Owner. I have been asked to consider what one of
`
`ordinary skill in the art before the priority date of the ’634 patent would have
`
`understood from the ’634 patent, including scientific and technical knowledge
`
`related to the ’634 patent. I have also been asked to consider whether the
`
`references relied on by Petitioner disclose or render obvious the inventions claimed
`
`by the ’634 patent.
`
`3.
`
`I understand that this proceeding is currently in a preliminary stage,
`
`and no IPR has yet been instituted. I have been asked to present my independent
`
`analysis with respect to certain issues relevant to the question of whether IPR
`
`should be instituted. I understand that I may be asked to present my complete
`
`analysis at a later date (if IPR is instituted), but the complete analysis is not
`
`1
`
`4
`
`
`
`
`
`necessary at this time. Accordingly, my independent analysis for relevant issues is
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`set forth below.
`
`4. My analysis is directed by my education, training, and experience as a
`
`person of ordinary skill in the art as of the priority date of the ’634 patent, which
`
`for purposes of my analysis here is assumed to be the effective filing date of the
`
`’634 patent—December 1, 2003.
`
`5.
`
`I am being compensated for my work in connection with this IPR
`
`proceeding at my standard hourly rate. My compensation is not in any way
`
`contingent on the substance of my opinions or the outcome of these proceedings.
`
`II.
`
`SUMMARY OF OPINIONS
`
`6.
`
`Based on my experience and expertise, discussed below, and my
`
`review of the references identified by Petitioner in this IPR for the ’634 patent, it is
`
`my opinion that the cited references do not render obvious at least claims 1, 4-7,
`
`10-13, and 16-18 of the ’634 patent.
`
`III. BACKGROUND AND QUALIFICATIONS
`
`7.
`
`I have more than twenty (20) years of experience in electrical
`
`engineering, computer science, and electronic messaging. The following
`
`paragraphs summarize some of my experience that is relevant to the technologies
`
`described within the ’634 patent. For further details, please refer to my curriculum
`
`vitae which is attached as Appendix A.

`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`
`8.
`
`I attended the Massachusetts Institute of Technology (MIT) from
`
`1988 to 1999, during which time I earned Bachelor of Science (1992), Master of
`
`Science (1995), and Doctor of Philosophy (1999) degrees in electrical engineering
`
`and computer science.
`
`9.
`
`I am the inventor of U.S. Patent No. 5,943,478, entitled “System for
`
`Popup Messaging over the Internet,” which describes a two-way messaging system
`
`like AOL Instant Messenger and MIT’s Zephyr service built at Internet scale.
`
`10.
`
`In 1996, I founded a company called Flash Communications, which
`
`focused on technology related to U.S. Patent No. 5,943,478 and associated
`
`technology that I had developed related to pop-up two-way messaging over the
`
`Internet. Flash Communications was sold to Microsoft Corporation in 1998, and
`
`Flash Communications’ messaging technology was incorporated into Microsoft’s
`
`Messenger service and Microsoft Exchange 2000 Instant Messaging Service.
`
`11. Notably, since around 1995, I have been using and working with AOL
`
`Instant Messenger (which was part of AOL’s subscription service in 1995 and
`
`1996, and in 1997 was released on the internet) until its demise both as a basis for
`
`competitive analysis and normal everyday usage.
`
`12. While working at Microsoft between 1999 and 2000, I worked in the
`
`Microsoft Exchange Server group. The group was responsible for all of
`
`Microsoft’s Messaging products including e-mail, instant messaging, and what
`
`3
`
`6
`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`
`later became their unified messaging offering that included telephony etc. I worked
`
`on many systems, including those that involved multicasting, a form of
`
`broadcasting.
`
`13. While at Microsoft I was an inventor of US Patent No. 6,260,148:
`
`Methods and systems for message forwarding and property notifications using
`
`electronic subscriptions; US Patent No. 6,415,318: Inter-enterprise messaging
`
`system using bridgehead servers; and US Patent No. 6,604,133: Inter-enterprise
`
`messaging system using bridgehead servers. Each of these patents is related to
`
`messaging, property subscription and notification, architectures for distributing
`
`broadcast messages, etc.
`
`14. While at Microsoft I worked on an XML parsing engine for the
`
`standard for IMPP, which is now known by the name XMPP, an XML language
`
`for Instant Messaging and Presence.
`
`15. Between 2000 and 2004, I worked as a consultant and investor at
`
`Nexaweb Corporation, where I helped implement several two-way messaging
`
`systems.
`
`16. Also in 2000, I started a company known as photo.net, which was a
`
`large online photography community known as one of the first social networking
`
`and photo sharing web sites. Messaging and broadcasting content were a core part
`
`of the offering of the site and I managed the implementation and hosting aspect of
`
`4
`
`7
`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`
`setting up and running the various SMTP, MTA, WAP, and SMS servers to enable
`
`communication with our user base. I built an application infrastructure to a scale
`
`that allowed me to be experienced with the issues in broadcasting messages to
`
`millions of users.
`
`17.
`
`In 2004, I founded another company, Scalable Display Technologies
`
`(SDT). I have been the Chairman of SDT since its founding and President until
`
`2014. SDT operates in the audio-video domain and has licensed software and
`
`firmware to various companies including Sony, Hitachi and NEC. I also
`
`implemented a distributed multimedia content playback system and spent a great
`
`deal of time dealing with multimedia transcoding and rendering systems. At SDT I
`
`was also involved building a network architecture where I had to consider and
`
`design a system that met our needs for discovery and direct communication using
`
`both broadcast and point to point communication mechanisms.
`
`18.
`
`I am on the advisory boards of several technology companies
`
`including: UnifySquare, which is a unified communications/real-time collaboration
`
`consultancy that focuses on telephony and instant messaging systems that
`
`Microsoft sells (Lync, an outgrowth of the company I sold to Microsoft);
`
`Nexaweb, which develops real-time web application frameworks using HTTPS;
`
`Permabit, which develops content addressable storage; and Evoque, which is an
`
`ecommerce enabling platform publisher.

`
`I have received several awards for my contributions as an inventor
`
`and entrepreneur, including the Global Indus Technovator Award 2009 and
`
`Laureate of 2009 Computer World Honors Program.
`
`20. Based on my experience and education, I believe that I am qualified to
`
`opine as to knowledge and level of skill of one of ordinary skill in the art at the
`
`time of the invention of the ’634 patent (which I further describe below) and what
`
`such a person would have understood at that time, and the state of the art during
`
`that time.
`
`IV. BASIS FOR OPINIONS
`
`21. My opinions and analysis set forth in this Declaration are based on my
`
`education, training, and experience as summarized above and detailed in my C.V.,
`
`as well as my review of the ’634 patent, its prosecution history, and the references
`
`identified by Petitioner in this IPR proceeding. I have also carefully reviewed the
`
`declaration from Dr. Sandeep Chatterjee (EX1102), which Petitioner submitted in
`
`support of its Petition in this IPR proceeding. I have also reviewed the Petition and
`
`each of the accompanying documents that are cited in the Petition, including those

`
`V.
`
`FIELD OF ART
`
`23. The ’634 patent generally relates to computer hardware, networking,
`
`and user experience design with electronic messaging. As such, it is my opinion
`
`that the ’634 patent is in the fields of computer hardware, networking, and/or user
`
`experience design, or an equivalent subject matter, and a complete understanding
`
`of the ’634 patent requires experience and appreciation of the challenges in design,
`
`development, and commercialization of such systems for consumer use.
`
`VI. PERSON OF ORDINARY SKILL IN THE ART
`
`24.
`
`I understand that the teaching of the prior art is viewed through the
`
`eyes of a person of ordinary skill in the art at the time of the invention. To assess
`
`the level of ordinary skill in the art, I understand that one can consider the types of
`
`problems encountered in the art, the prior solutions to those problems found in
`
`prior art references, the speed with which innovations were made at that time, the
`
`sophistication of the technology, and the level of education of active workers in the
`
`field.
`
`25.
`
`In my opinion, a person of ordinary skill in the art relevant to the ’634
`
`patent at the time of its invention would have had a bachelor of science degree in
`
`9
`
`12
`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`
`Computer Engineering/Computer Science or similar subject matter, or at least
`
`approximately two years of work or research experience in the fields of computer
`
`hardware, networking, and/or user experience design, or an equivalent subject
`
`matter, sufficient to understand fundamental computer networking and hardware
`
`architecture and user-interface design. My analysis is thus based on the
`
`perspective of a POSITA having at least this level of knowledge and skill in the
`
`time leading up to the ’634 patent. I have been informed that the earliest claimed
`
`priority date of the ’634 patent is the effective filing date of U.S. Provisional
`
`Application No. 60/525,958—December 1, 2003, and I have applied this
`
`timeframe in my analysis as being the relevant time of the ’634 patent.
`
`VII. THE ’634 PATENT
`
`A. Overview of the ’634 patent
`
`26. The ’634 patent generally relates to “previewing new events in a
`
`computing device having a plurality of applications for managing respective
`
`events.” EX1101, Abstract; Title (“Previewing a New Event on a Small Screen.”).
`
`For example, the ’634 patent describes notifying and previewing a new event on a
`
`computing device, such as notifying and previewing receipt of new messages on a
`
`mobile device. The claims recite a visual modification of an electronic messaging
`
`icon to display information related to a “count of the plurality of different
`
`10
`
`13
`
`
`
`
`
`messaging correspondents for which one or more of the electronic messages have
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`been received and remain unread.”
`
`27. The ’634 patent identifies various challenges associated with display
`
`of information on mobile devices (e.g., having a small screen). “With the
`
`proliferation of communications services available on wireless mobile devices, it
`
`becomes increasingly complex to create a single device that can excel at many
`
`different functions.” EX1101, 1:18-31. “However, many users of wireless
`
`handheld devices desire to have multiple services and functionality on a single
`
`device.” Id. Mobile uses thus receive messages from many separate applications,
`
`which “presents a number of challenges to the designer of a user interface.”
`
`EX1101, 1:31-40. These applications include “more than one Instant Message-
`
`type service,” or “corporate and personal email.” Id., 1:53-65. Some prior systems
`
`responded to each incoming message by showing a notification “on a major
`
`portion of the main screen.” Id., 1:38-52. The notification was not application-
`
`specific, however, forcing users “to check each of their … applications separately”
`
`to determine which application triggered the notification. Id. This process could
`
`involve navigating to “a main or home screen and one or more sub-screens that
`
`may be navigated from the main screen.” Id., 1:41-43, 60:64. The ’634 patent
`
`identified that “[c]hecking each service is inconvenient.” This makes it difficult
`
`for a user to check the new event quickly and in a manner to optimize the control
`
`11
`
`14
`
`
`
`
`
`of a single wireless mobile device running multiple instant messaging services and
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`email counts. Id., 1:60-68.
`
`28. The ’634 patent solved such shortcomings by notifying/previewing a
`
`user with information regarding messages received on a mobile device despite
`
`being limited in screen size. In particular, the ’634 patent provides a solution that
`
`involved visually modifying a messaging icon to provide a count of certain specific
`
`events, such as a count of the plurality of different messaging correspondents for
`
`which one or more of the electronic messages have been received and remain
`
`unread.” Id., cls. 1, 7, and 13 (emphasis added); 8:8-13, 8:19-29.
`
`29. The ’634 patent describes a wireless communication device may run
`
`multiple applications, and such applications may be represented by application
`
`icons on a graphical user interface of the device. Id. EX1101, Abstract, cls. 1, 7,
`
`and 13, 3:35-39, 7:32-47, FIG. 3. Figure 3 reproduced below shows an
`
`“exemplary main screen 300,” that includes an “application portion 301 for
`
`displaying and manipulating icons (e.g. 304-312) for various software applications
`
`and functions enabled by a mobile station 202.” EX1101, 7:32-41.
`
`12
`
`15
`
`
`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`EX1101, FIG. 3.
`
`
`
`30. The wireless communication device receives a plurality of electronic
`
`messages, such as messages from a number of different messaging correspondents.
`
`Some prior systems were focused only on a number of received messages. The
`
`claims of the ’634 patent, in contrast, recite visually modifying the displayed icon
`
`to include “a numeric character representing a count of the plurality of different
`
`messaging correspondents for which one or more of the electronic messages have
`
`been received and remain unread.” Id., cls 1, 7, and 13, 8-13, 8:19-29, FIG. 4.
`
`Display of a count directed to “the plurality of different messaging correspondents
`
`for which one or more of the electronic messages have been received and remain
`
`unread,” presents different information to a user (e.g., as compared to a raw count
`
`of new messages). I note that some such advantages were explicitly discussed
`
`during original prosecution. “By displaying the number of distinct correspondents
`
`13
`
`16
`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`
`from whom messages have been received, Applicant’s claimed invention opens
`
`new possibilities for users of such communications.” See, e.g., EX1113, 677; see
`
`also id., 678 (“by expending such resources and modifying an icon associated with
`
`a corresponding communications application, as claimed, they could allow a user
`
`to very efficiently track sometimes crucial information while making very efficient
`
`use of display resources, and significantly reducing input, output, display, and
`
`other processing tasks that previously were required for the users to obtain and
`
`track such information.”).
`
`31. The ’634 patent also describes that the wireless communication device
`
`can display a preview of content associated with a received electronic message.
`
`EX1101, Abstract, cls. 6, 12, and 18; 8:41-42, 8:51-65, FIGS. 6 and 7. This could
`
`include a preview of a portion of the received message.
`
`B.
`
`Prosecution History of the ’634 patent
`
`32.
`
` The application leading to the ’634 patent was filed on February 24,
`
`2004, claiming priority to U.S. Provisional Application No. 60/525,958 filed on
`
`December 1, 2003. The ’634 patent was allowed on March 30, 2012 and issued on
`
`June 26, 2012.
`
`33. The ’634 patent went through several office action/response cycles,
`
`with several references and combinations of references applied in the office
`
`actions. I note that dozens more references were considered by the Examiner,
`
`14
`
`17
`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`
`including those listed in the ’634 patent. In particular, the last two Office Actions
`
`dated May 19, 2011, and October 26, 2011 included rejections based on Wagner
`
`(U.S. 2004/0155908) and Canfield (U.S. 2004/0056893) (referred to by Petitioner
`
`in IPR2019-00939 as “Considered Canfield”). EX1113, 607-624; 707-728. I
`
`understand that the Examiner relied on Wagner for most elements of claim 1,
`
`including visually modifying an icon. Id. The Examiner cited Wagner’s
`
`description that “a mail icon may display a counter that changes to indicate the
`
`number of unread messages a user has.” Id. The Examiner proposed a
`
`modification of Wagner based on Considered Canfield to visually modify
`
`Wagner’s icon to include “a numeric character representing a count of the plurality
`
`of different messaging correspondents for which one or more of the electronic
`
`messages have been received and remain unread,” instead of Wagner’s existing
`
`“number of unread messages.” EX1113, 611. As a motivation for this
`
`modification, the Examiner concluded that a POSITA would have made this
`
`combination “in order to provide the user with comprehensive statistics regarding
`
`concurrent messaging sessions.” Id., 612-613 (emphasis added).
`
`34. Applicant submitted responses to each of these Office Actions,
`
`identifying multiple distinctions and related advantages of the claims over Wagner,
`
`Considered Canfield, and the other art of record. Particularly, the responses
`
`explained that Considered Canfield is concerned with instant messaging “sessions”
`

`
`
`Case IPR2019-00925

`
`
`
`or “conversations,” unlike the “different messaging correspondents,” as claimed.
`
`EX1113, 814. This distinction between tracking a number of “messages or
`
`conversations” and “different messaging correspondents is reflected in the record:
`
`As discussed during the 6 March interview, counting either a total
`
`number of unread messages or a number of conversations does not, for
`
`example, enable a user to track the number of correspondents from
`
`whom the user has received unread messages. By tracking a number
`
`of correspondents, rather than a number of messages or
`
`conversations, a device presents different information to a user.
`
`For example, a single correspondent might either (a) send a plurality
`
`of messages to the user, or (b) start and stop a number of
`
`conversations, without affecting the number of distinct correspondents
`
`from whom the user has received unread messages.
`
`EX1113, 814 (emphasis added). There are a number of advantages that can flow
`
`from displaying a number of “different messaging correspondents.” For example,
`
`the responses explained that “the advantage of being able to know that a new
`
`correspondent has attempted to communicate can be of great importance, and it is
`
`lost if simple numbers of current or new IM sessions is tracked.” Id., 678. This is
`
`because, for example, “a single correspondent can initiate an unlimited number of
`
`new IM sessions, just as he/she can send any number of e-mails or other types of
`
`messages.” Id., 678-679 (emphasis added) (“Applicant’s claimed solution of
`
`tracking distinct correspondents provides unique and unobvious advantages.”).

`
`
`
`
`
`35. Based on my knowledge and experience in this field and my analysis
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`of the prosecution history of the ’634 patent, it is apparent that the Examiner
`
`concluded that the claims of the ’634 patent recited elements absent from the
`
`Wagner and Considered Canfield references, and absent from the other cited
`
`references. This conclusion is confirmed by these office actions and responses,
`
`which were followed by a notice of allowance, and the Examiner’s express
`
`statement of reasons for allowance. The Examiner indicated that the “prior art of
`
`record fails to disclose a numeric character that represents a count of the plurality
`
`of different messaging correspondents for which one or more of the electronic
`
`messages have been received and remain unread.” Id., 826.
`
`VIII. INTERPRETATIONS OF THE ’634 PATENT CLAIMS AT ISSUE
`
`36.
`
`I have been asked to provide my interpretation of the following terms
`
`of the ’634 patent set forth below. In providing the following interpretations, I
`
`have carefully considered and applied the claim construction standard referred to in
`
`Section XIII below. Infra, ¶79 ((“interpreted according to their ‘ordinary and
`
`customary meaning’ under the Phillips standard”). I understand that the district
`
`court in a related proceeding involving the ’634 patent issued a Ruling on Claim
`
`Construction (“Markman Order”) on April 5, 2019. See EX2002, 19-27. I have
`
`reviewed the sections of the Markman Order that pertain to the ’634 patent. I
`
`17
`
`20
`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`
`understand that the claim construction standard under Phillips that applies in this
`
`review is the same standard that the court applied in its Markman Order.
`
`A.
`
`“wireless communication device” (All challenged claims)
`
`37.
`
` All claims recite a “wireless communication device.” I have been
`
`informed that the District Court concluded that “no construction of the term
`
`‘wireless communication device’ is necessary” under the Phillips standard.
`
`EX2002, 24. I note that the District Court clarified that “wireless communication
`
`device” is not limited to “small-screen” devices. EX2002, 20-23 (citing EX1101,
`
`1:36-40; 3:9-12; 4:55-5:9). For purposes of my analysis in this IPR proceeding, I
`
`adopt and apply this construction, which is consistent with the ’634 patent
`
`specification and the understanding of a POSITA. Id.
`
`38. Grounds 3-4 of the Petition are duplicative with Grounds 1-2, except
`
`that Grounds 3-4 add Strom to purportedly account for an interpretation in which
`
`the claim language requires a “small-screen wireless mobile device.” Petition, 25.
`
`As noted above, the District Court noted that the term “wireless communication
`
`device” is not limited to a “small-screen wireless mobile device.” Grounds 3-4
`
`suffer from the same fatal flaws as Ground 1-2.
`
`B.
`
`“messaging correspondent” (All challenged claims)
`
`39.
`
` All claims recite a “messaging correspondent.” I have been informed
`
`that the District Court concluded the claim phrase “messaging correspondent”
`
`18
`
`21
`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`means a “distinct sender of an electronic message.” EX2002, 23-25. Based on my
`
`knowledge and experience in the field and my review of the ’634 patent
`
`specification, this interpretation is consistent with the understanding of a POSITA
`
`and the ’634 patent specification. See, e.g., 8:8-24; 8:51-55; 9:21-27; 1:53-65. For
`
`purposes of my analysis in this IPR proceeding, I adopt and apply this
`
`construction.
`
`40.
`
`It also appears that the District Court rejected the construction
`
`proposed by the Petition. The District Court explained that “[n]othing in the plain
`
`language of the claims limits the term ‘messaging correspondent’ by tying it to a
`
`particular messaging account.” EX2002, 24-25; EX1101, 1:59-60 (“a user may
`
`have a corporate and personal e-mail account”). I agree with this statement,
`
`especially given the ’634 patent specification’s description that a user may have
`
`multiple messaging accounts.
`
`“a numeric character representing a count of the plurality
`C.
`of different message correspondents for which one or more of the
`electronic messages have been received and remain unread” (All
`challenged claims)
`
`41.
`
`Each challenged claim recites this phrase. I have been informed that
`
`the District Court construed this phrase under the Phillips standard to mean “a
`
`numeric character representing the number of different messaging correspondents
`
`for one or more of the plurality of electronic messages that have been rec eived and
`
`remain unread.” EX2002, 27. Based on my knowledge and experience in the field
`
`19
`
`22
`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`
`and my review of the ’634 patent specification, this construction is consistent with
`
`the ’634 patent specification and its prosecution history. EX1101, 8:59-62; cl. 1.
`
`For purposes of my analysis in this IPR proceeding, I adopt and apply this
`
`construction.
`
`IX. ANALYSIS REGARDING THE CLAIMS OF THE ’634 PATENT IN
`LIGHT OF THE PRIOR ART
`
`A. Ording, Abiko, Crumlish, and Dvorak (Ground 1)
`
`42.
`
`I have been asked by Patent Owner to evaluate the contentions of the
`
`Petition and Dr. Chatterjee regarding the allegation that Ording, Abiko, Crumlish,
`
`and Dvorak render obvious the invention set forth in claims 1, 4-7, 10-13, and 16-
`
`18. I currently hold the opinions expressed in this declaration. Based upon my
`
`knowledge and experience in this field and my review of Ording, Abiko, Crumlish,
`
`and Dvorak, it is readily apparent that this proposed combination of references fails
`
`to disclose several elements recited in claims 1, 4-7, 10-13, and 16-18. Although I
`
`identify a number of specific claim elements below (infra, ¶¶43-76), I note that
`
`there may be additional claim elements lacking from the proposed combination of
`
`references even though they are not expressly identifi
