`
`INTRODUCTION AND BACKGROUND
`
`1.
`
`My name is Justin Douglas Tygar.
`
`I am a tenured, full Professor at the University
`
`of California, Berkeley, with a joint appointment in the Department of Electrical Engineering
`
`and Computer Science (Computer Science Division) and the School of Information. Prior to
`
`joining UC Berkeley in 1998, I was a tenured faculty member in the Computer Science
`
`Department at Carnegie Mellon University.
`
`2.
`
`I am an expert in software engineering, computer security, and cryptography.
`
`I
`
`have taught courses in software engineering and computer security, at the undergraduate,
`
`master’s, and Ph.D. level at both UC Berkeley and Carnegie Mellon University.
`
`3.
`
`I have also co-written three books that address networking technology and
`
`security for networking technology, and one of those books has been translated into Japanese. I
`
`have helped design the DETER networking testbed supported by the US. National Science
`
`Foundation and the US. Department of Homeland Security that is a widely used framework for
`
`testing networking. Further, I led the team that designed the SWOON overlay network used to
`
`test mobile networking in that environment.
`
`4.
`
`Among my awards are the National Science Foundation Presidential Young
`
`Investigator Award and the Kyoto Fellowship.
`
`5 .
`
`I was the co-inventor of a major electronic commerce payment system called
`
`NetBill which has been patented, implemented, and licensed to a commercial company
`
`CyberCash.
`
`I am the UC Berkeley lead of the US. National Science Foundation Science and
`
`Technology Center TRUST, which studies issues associated with networking and security. The
`
`US. State Department chose my project at UC Berkeley to examine the security and networking
`
`issues, including load-balancing issues, for communications protocols and software to support

`
`Internet freedom and allow users to bypass national firewalls in countries such as China, Iran,
`
`and Syria.
`
`I am also associated with the Intel Science and Technology Center SCRUB, which
`
`focuses on issues related to networking and security.
`
`I helped design the security standards for
`
`the US Postal Service’s Information Based Indicia Program (cryptographic postal indicia).

`
`Appendix A of my initial declaration in support of SightSound Technologies
`
`LLC’s (“SightSound”) Opening Claim Construction Brief contains a list of court cases for which
`
`I have provided testimony at trial or at deposition since January 1, 2007. Appendix B of that
`
`declaration also contains my curriculum vitae (including a full publication list for the last ten
`
`years).
`

`
`Counsel for SightSound requested that I provide expert analysis pertinent to claim
`
`construction issues in the case SightSound Technologies, LLC v. Apple, Inc, Civ. Action No.
`
`2:11—cv-01292-DWA, in the United States District Court for the Western District of
`
`Pennsylvania.
`
`I am charging $500/hour for work performed (limited to a maximum charge of
`
`$5000/day). My compensation is in no way dependent on the outcome of the case.
`

`
`In preparing to submit this Declaration, I have read the following materials: U.S.
`
`Patent No. 5,191,573 (the “‘573 Patent”), U.S. Patent No. 5,675,734 (the “‘734 Patent”), and
`
`U.S. Patent No. 5,966,440 (the “‘440 Patent”) (collectively, the “Hair Patents”); the parties’ Joint
`
`Disputed Claim Terms Chart (Aug. 8, 2012); the Declaration of Dr. John PJ. Kelly (which I
`
`refer to as the “Kelly Declaration” or “Kelly Decl.”), dated September 7, 2012; each parties’
`
`opening brief; and other materials cited herein.
`
`RESPONSE TO DECLARATION OF DR. KELLY
`
`Telecommunications Lines
`
`9.
`
`Dr. Kelly references the prosecution history of the Hair patents and opines that
`
`Page 00003
`
`Page 00003
`
`
`
`Case 2:1lvcv-01292-DWA Document 104-3 Filed 09/28/12 Page 4 of 16
`
`“one of ordinary skill in the art would interpret that the applicant disclaimed from coverage
`
`anything less than the usage of telecommunications lines for every component in the connection
`
`from the first party to the second party.” Kelly Decl. 1] 20.
`
`I disagree with this conclusion, and
`
`disagree that the cited text supports this conclusion.
`
`10.
`
`Lightner required the second party to be at the location of the vending machine to
`
`transfer money to the first party. In contrast, the claims of the Hair patents require, in various
`
`terms, that the first party be at a first party location while the second party is at a second party
`
`location remote from the first party location. See ‘573 PH, 06/25/92 Amend. at 20. The
`
`emphasis was on the relative locations of the parties at the time money was transferred, not on
`
`the nature of the method of communication between them. This is consistent with Mr. Hair’s
`
`argument that “Lightner .
`
`.
`
`. does not teach or suggest the use of telephone or telecommunication
`
`lines with respect to the transfer of money.”
`
`11.
`
`Accordingly, I stand by my Opinion put forth in paragraphs 17 to 25 of my
`
`declaration of September 7, 2012. In 1988, one of reasonable skill in the art would have
`
`understood “telecommunications lines” to include telephone lines, fiber-optic cable, wireless
`
`networking, and several other mediums of electronic communication (such as cellular telephones
`
`and microwave transmissions). The terms would have covered transmissions using metal wires,
`
`non-metallic fiber—optic cables, and wireless transmissions using electromagnetic particles.
`
`Line
`
`12.
`
`Dr. Kelly again references the prosecution history of the Hair patents and opines
`
`that “one of ordinary skill in the art would understand the claim term ‘line,’ as used in the
`
`asserted patents, to mean a ‘wire.”’ Kelly Decl.1]1l 15, 27.
`
`I disagree with this conclusion, and
`
`disagree that the cited text supports this conclusion.

`
`
`Case 2:11—cv-01292-DWA Document 104-3 Filed 09/28/12 Page 5 of 16
`
`13.
`
`Dr. Kelly Observes that the Examiner found a claim including the term
`
`“telecommunication link” indefinite and rejected in on this basis. In response, Mr. Hair amended
`
`the claim to use “telecommunication line” instead. Kelly Decl. ll 24 (citing ‘573 PH 02/24/92
`
`Office Action at 6; ‘573 PH 06/25/92 Amend. at 6). The rejection was made “for failing to
`
`particularly point out and distinctly claim the subject matter which applicant regards as the
`
`invention.” ‘573 PH 02/24/09 Office Action at 6. The Examiner cited a portion ofthe statute in
`
`making his rejection, explaining that the “written description” must provide sufficiently “exact
`
`terms as to enable any person skilled in the art to which it pertains, or with which it is most
`
`nearly connected, to make and use the same.” Id. (citing 35 U.S.C. § 112) (emphasis added).
`
`The Examiner went on to state that “the ‘telecommunications link’ is not well connected in the
`
`system.” Id. Thus, the Examiner did not, as Dr. Kelly states, reject the use of “an intangible
`
`‘1ink’” (Kelly Dec. 1} 15), but only found that one of ordinary skill in the art, on reading the
`
`patent, would not understand what was meant by “telecommunication link.”
`
`14.
`
`My opinion is that one of ordinary skill in the art would understand that, by
`
`changing “link” to “line” in response to an indefiniteness rejection, no narrowing of scope was
`
`intended.
`
`15.
`
`Dr. Kelly opines “that the applicant, in the same amendment, was also
`
`distinguishing Lightner as prior art.” Kelly Decl. 1H6. However, the applicant noted that
`
`“Lightner, US. Patent 3,718,906 is currently not a basis of rejection of the claim” and sought to
`
`clarify the differences between “new Claim 23” and Lightner.
`
`‘573 PH 6/25/92 Amend. at 19.
`
`No reference was made in the applicant’s argument regarding a distinction between “line” and
`
`“link.” Thus, one of ordinary skill in the art would understand that the applicant’s discussion of
`
`Lightner was unrelated to the changing of “link” to “line” in response to the indefiniteness
`

`
`
`
`Case 2:11—cv—01292-DWA Document 104—3 Filed 09/28/12 Page 6 of 16
`
`rejection.
`
`16.
`
`Dr. Kelly opines that the following quote from the prosecution history shows that
`
`the applicant intended “line” to require a physical connection, while a “cellular call” does not:
`
`[In the claimed invention], a customer can enjoy the ability to purchase audio or
`video digital signals wherever the customer wishes as totally dictated by the
`customer (assuming there is a telecommunications line at hand—in the U.S., there
`is a phone or cable line just about everywhere or a cellular call can be made
`literally everywhere) .
`.
`.
`.
`
`Kelly Decl. 1126; see ‘440 PH 4/14/97 Amend. at 14.
`
`I disagree with Dr. Kelly. In my opinion,
`
`this quote would show one of ordinary skill in the art that phone lines, cable lines, and cellular
`
`calls are all examples of telecommunications lines.
`
`17.
`
`Dr. Kelly relies on a number of dictionary definitions to support his opinion that
`
`“the claim term ‘line,’ as used in the asserted patents, [means] a ‘wire.”’ Kelly Decl. W27-28.
`
`However, the dictionaries he uses also contain a number of broader definitions.
`
`18.
`
`For example, Webster ’5 II New Riverside University Dictionary (1988) at p. 695
`
`defines “line” as “a functioning or open telephone connection” or “a source of information.”
`
`Webster ‘s Ninth New Collegiate Dictionary (1988) also defines “line” as “a telephone
`
`connection.” These definitions comport with the use of the term in the Hair patents that “line” is
`
`not restricted to mean the narrow term “wire.”
`
`Electronic
`
`19.
`
`In addition to the cited definitions in Dr. Kelly’s report, Chambers Science and
`
`Technology Dictionary (1988) at p.294 notes that “Telecommunications, radar, and computers all
`
`use electronic components and techniques.” In many of the asserted claims, “electronic” is used
`
`to refer to the nature of the devices involved, not to the methods by which information is
`
`transferred.

`
`20.
`
`Regarding the proper understanding of “digital audio signal[s],” Dr. Kelly opines
`
`that “modules, available in 1987, explicitly bundled the samples in the same file as the
`
`instructions.” Kelly Decl.1l39. As I stated in my September 7, 2012 declaration, one of ordinary
`
`skill in the art in 1988 would recognize that any digital data can be playable as an audible sound
`
`wave. What distinguishes “digital audio signals” from other digital data is that it is a genuine,
`
`standalone substitute for studio— or performance-quality sound. Tygar Decl. W 12—13. That is,
`
`“digital audio signals” are digitized sounds, not merely computer instructions to generate sound.
`
`Small portions of Dr. Kelly’s modules are digitized sounds, but the modules themselves are
`
`computer instructions to generate sound through various manipulations of those digitized sounds.
`
`21.
`
`I disagree with Dr. Kelly that “it would be ambiguous whether these modules
`3”
`constituted ‘digital audio signals. Kelly Decl. 1B 9. In my opinion, one of ordinary skill in the
`
`art would understand that modules are not “digital audio signals.”
`
`22.
`
`Dr. Kelly also opines that since MIDI files can be stored on compact discs, and
`
`digital audio can also be stored on compact discs, MIDI files must be “digital audio signals.”
`
`Kelly Decl.1l40. If this were the criteria to be used, all computer files, including images, Word
`
`documents, and Windows applications, would be “digital audio signals,” since they can be stored
`
`on CDs. In my opinion, one of ordinary skill in the art would not assume that any file that can be
`
`stored on a CD would fall within the definition of “digital audio signals.”
`
`Hard Disk; Hard Drive
`
`23.
`
`Dr. Kelly cites a number of dictionary definitions in support of his proposed
`
`constructions of these terms. One of the sources he cites, the IBM Dictionary of Computing
`
`(1994) at p.308 includes the following note: “The term hard disk is also used loosely in the
`
`industry for boards and cartridges containing microchips or bubble memory that simulate the
`
`Page 00007
`
`Page 00007
`
`
`
`Case 2:1l—cv—01292—DWA Document 104-3 Filed 09/28/12 Page 8 of 16
`
`operations of a hard disk drive.” This supports the better understanding of the term, as I
`
`explained in my prior declaration, that the terms “hard disk” and “hard drive” refer to non—
`
`volatile storage devices that can be arbitrarily overwritten. In sum, a person of skill in the art in
`
`1988 would recognize the term hard drive to cover non—volatile storage devices utilizing rotating
`
`magnetic disks as well as solid—state drives.
`
`Second Party Hard Disk (‘440 Patent, Claim 16)
`
`24.
`
`Dr. Kelly opines that one of ordinary skill in the art would be unable to determine
`
`how the second party hard disk in claim 16 relates to the remainder of the claimed system. Kelly
`
`Decl. 1159. However, Dr. Kelly goes on to identify the best possible antecedent basis for the term
`
`as a “non-volatile storage portion that stores the desired digital video or digital audio signals.”
`
`1d. 1160. He also opines that “hard disk” is a narrower term than “non-volatile storage portion.”
`
`Id.
`
`In my opinion, if “hard disk” is a narrower term than “non-volatile storage portion,” and if
`
`“non-volatile storage portion” provides the antecedent basis for “the second party hard disk,”
`
`then one of ordinary skill in the art would understand “the second party hard disk” to be the
`
`“non—volatile storage portion,” and to provide the additional limitation that the storage portion be
`
`a hard disk.
`
`Means-Plus—Function Limitations
`
`25.
`
`I will next respond to certain points raised by Apple and Dr. Kelly with respect to
`
`the means-plus—function limitations at issue.
`
`26.
`
`As an initial matter, I understand that Apple and Dr. Kelly have presumptively
`
`treated all the means—plus function limitations at issue as reciting functions requiring specially—
`
`programmed computers of which an algorithmic disclosure in the patent is necessary. Kelly
`
`Decl. 111165—66.
`
`I have been informed, however, that this is only one side in the analysis of
`
`Page 00008
`
`Page 00008
`
`
`
`Case 2:11-cv-01292-DWA Document 104—3 Filed 09/28/12 Page 9 of 16
`
`computer—implement means—plus function limitations.
`
`1 am informed that for certain computer-
`
`implemented functions, such as storing, receiving, and processing (without any narrower
`
`constructions), any general purpose computer without special programming can be used.
`
`In such
`
`a situation, I understand that the patent need only disclose a general purpose processor that
`
`performs the function.
`
`27.
`
`A person of ordinary skill in the art would understand that certain recited
`
`functions in properly analyzed means-plus function limitations, such as storing, can be
`
`performed by a general purpose processor of a computer, 6. g. , an integrated circuit.
`
`28. With respect to the means or mechanism for connecting electronically and the
`
`connecting means or mechanism, I understand that Apple and Dr. Kelly contend that the claimed
`
`structures for claims 11 and 16 of the ‘734 patent, and claims 24, 31, and 83 of the ‘440 patent,
`
`are non-structural “functional features” and are thus insufficient to rebut the presumption that
`
`this limitation should be analyzed as a means-plus function claim. Kelly Decl. 1l77.
`
`I disagree
`
`with this assessment. For instance, the language of Claim 11 and 16, which Dr. Kelly includes in
`
`his declaration (id. 1W4), states:
`
`means or a mechanism for connecting electronically Via the telecommunications
`lines the first memory with the second memory such that the desired digital Video
`or digital audio signals can pass therebetween, said connecting means or
`mechanism in electrical communication with the transferring means or
`mechanism, said connecting means or mechanism comprises a first control unit in
`possession and control of the first party, and a second control unit in possession
`and control of the second party, said first control unit comprises a first control
`panel, first control integrated circuit and a sales random access memory, said sales
`random access memory and said first control panel in electrical communication
`with said first control integrated circuit, said second control unit comprising a
`second control panel, a second control integrated circuit, an incoming random
`access memory and a playback random access memory, said second control panel,
`said incoming random access memory and said playback random access memory
`in electrical communication with said second control integrated circuit; (‘734
`patent, cl. 11 (emphasis added»

`
`means or a mechanism for connecting electronically via telecommunications lines
`the first memory with the second memory such that the desired digital video or
`digital audio signals can pass therebetween, said connecting means or mechanism
`in electrical communication with the transferring means or mechanism, we}
`connecting means or mechanism comprises a first control unit disposed at the first
`party location and a second control unit disposed at the second party location
`remote from said first control unit, said first control unit comprises a first control
`panel, first control integrated circuit, and a sales random access memory
`connected to the first hard disk for temporarily storing a replica of the desired
`digital video or digital audio signals to be transmitted from the first control unit,
`said sales random access memory, said first hard disk and said first control panel
`in electrical communication with said first control integrated circuit, said second
`control unit comprising a second control panel, a second control integrated circuit,
`and an incoming random access memory which temporarily stores the desired
`digital video or digital audio signals transmitted from the sales random access
`memory, said playback random access memory connected to the incoming
`random access memory for temporarily storing a replica of the desired digital
`video signals or digital audio signals to be played, said incoming random access
`memory connected to said second party hard disk, said second control panel, said
`incoming random access memory, said second party hard disk and said playback
`random access memory in electrical communication with said second control
`integrated circuit; (‘734 patent, cl. 16 (emphasis added))
`
`29.
`
`A person of ordinary skill in the art would not consider the recited components
`
`that comprise the means for connecting to be non—structural functional features. Claims 11 and
`
`16 of the ‘734 patent, for example, claim that the first control unit “comprises a first control
`
`panel, first control integrated circuit, and a sales random access memory,” where the “sales
`
`random access memory and said first control panel [is] in electrical communication with said
`
`first control integrated circuit.” And, likewise, the “second control unit [is claimed to comprise]
`
`a second control panel, a second control integrated circuit, an incoming random access memory
`
`and a playback random access memory.”
`
`30.
`
`Claim 16 of the ‘734 patent adds the further limitation that the “sales random
`
`access memory [is] connected to [the] first hard disk” and that the “incoming random access
`
`memory [is] connected to [the] second hard disk.”
`
`31.
`
`In fact, control units, as disclosed in the patent specifications, include very
`
`-10-

`
`
`Case 2:11—CV-01292—DWA Document 104—3 Filed 09/28/12 Page 11 0f 16
`
`specific, physical structures, such as a control panel, control integrated circuits, and RAM for
`
`sales, storage and playback. See, e.g.,"440 patent at col. 37-67; Figs. 1-2; ‘734 patent at col.
`
`4:35-65; Figs. 1—2.
`
`32.
`
`A person of ordinary skill in the art would unquestionably understand these to be
`
`structural components. This is also especially true in light of the physical, electrical connections
`
`among the claimed components within the control units. See, e. g., ‘734 patent, cl. 11, 16.
`
`33.
`
`To support his conclusion that the claimed control units are non-structural
`
`“functional features,” Dr. Kelly cites one line from each specification (‘734 patent, col. 4:3 8—39;
`
`‘440 patent, col. 4:39—41), which states: “The design of the control units would incorporate the
`
`following functional features.” Kelly Decl. 1W7. However, the remainder of the passage is
`
`directed to identifying structural components (as also illustrated in Figures 1 and 2) of which a
`
`person of ordinary skill in the art has long understood to be physical structures in a computing
`
`system, 6. g. , integrated circuits and memory chips. See ‘440 patent, col. 37-67; ‘734 patent, col.
`
`4:35—65.
`
`34.
`
`I also understand Dr. Kelly to opine that the claims do not explain the relationship
`
`between the first control unit and the second control unit. Kelly Decl. 1178. But, claims 11 and
`
`16 of the ‘734 patent describe the relationship between the two through a connection Via
`
`telecommunications lines to the memory within each unit:
`
`Means or a mechanism for connecting electronically via the telecommunications
`lines the first memory with the second memory .
`.
`. said connecting means or
`mechanism comprises a first control unit [] and a second control unit .
`.
`. [where]
`said first control unit comprises a first control panel, first control integrated circuit
`and a sales random access memory .
`.
`. [and] said second control unit comprising
`a second control panel, a second control integrated circuit, and incoming random
`access memory and a playback random access memory .
`.
`. (‘734 patent, cl. 11)

`Means or a mechanism for connecting electronically via telecommunications lines

`
`. said first
`.
`mechanism comprises a first control unit [] and a second control unit .
`control unit comprises a first unit comprises a first control panel, first control
`integrated circuit, and a sales random access memory connected to the first hard
`disk .
`.
`. said second control unit comprising a second control panel, a second
`control integrated circuit, and an incoming random access memory .
`.
`. (‘734
`patent, cl. 16)
`
`35.
`
`The specifications also corroborate this relationship in, for example, Figs. 1 and 2,
`
`as well as column 4, lines 12—16 and column 6, lines 38—45 of the ‘734 patent, which illustrate
`
`and explain to one of skill the art that the control units maintain their relationship to one another
`
`via telecommunications lines. See also ‘440 patent, Figs. 1-2, col. 4: 14-18, 6:41—48.
`
`36.
`
`With respect to claims 23, 29, 82, and 88 of the ‘440 patent, which I believe—~as
`
`do Apple and Dr. Kelly—should be interpreted as a means-plus function limitation, I understand
`
`Apple and Dr. Kelly to challenge the level of disclosure to perform the recited function of
`
`connecting electronically. Kelly Decl. ‘|l77.
`
`I disagree that the patent does not disclose a specific
`
`methodology to perform this function.
`
`37.
`
`The Specification states that the function of connecting electronically is done “via
`
`telecommunications lines,” which links the “first memory with a receiver of the second party
`
`while the receiver is in possession and control of the second party.” ‘440 patent, col. 8:3—6. This
`
`receiver is included as part of the second party control integrated circuit. Id. col. 6:64-66.
`
`Indeed, to properly form a connection, the patent describes that the first party control unit
`
`includes a control integrated circuit electrically connected to memory, and then to the user’s
`
`receiver (included as part of the second party control integrated circuit) through
`
`telecommunications lines. Id. at 7:20—26.
`
`38.
`
`Also, in light of this and in looking at Figure 1, which is described to serve as a
`
`flow chart (id. col. 3:45—53), a person of ordinary skill in the art would understand that a
`
`connection should in fact be made from memory 20C through the control integrated circuit 20B

`
`to control integrated circuit 50B, which includes a receiver. See ‘440 patent, Fig. 1. I have also
`
`been informed that a flow chart, such as this, can sufficiently disclose to one of skill in the art a
`
`specific methodology for performing the claimed function to satisfy the definiteness requirement
`
`of a means-plus function limitation.
`
`39.
`
`On top of that, the control integrated circuits are described in the patent to control
`
`and execute the commands of the agent and user, and regulate the electronic transfer of digital
`
`signals throughout the system. “440 patent, col. 4:45-48. As explained in my opening
`
`declaration, a person of ordinary skill in the art would understand that regulating the electronic
`
`transfer of digital signals from a user to an agent necessarily involves the formation of an
`
`electronic connection to facilitate that transfer.
`
`40.
`
`Accordingly, the patent sufficiently describes a methodology for implementing
`
`the function of “connecting electronically” on a properly configured control integrated circuit.
`
`41. With respect to the “means or mechanism for transmitting” and “transmitting
`
`means or mechanism,” Dr. Kelly says these limitations fail to recite sufficient structure to rebut
`
`the presumption the limitation should be analyzed as a means-plus—function limitation. Kelly
`
`Decl. W84—87.
`
`I understand Dr. Kelly’s contention in this regard to be based on his belief that a
`
`person of ordinary skill in the art would not understand how the recited transmitter and receiver
`
`operate and interact.
`
`42.
`
`I have been informed that the test is whether a person of ordinary skill in the art
`
`would understand the claim to recite sufficient structure to rebut the presumption that it should
`
`be treated as a means—plus function claim. That is the case here as the claims recite the
`
`transmitter and receiver as structures linked to the claimed function.
`
`43.
`
`One of ordinary skill in the art in 1988 would have been aware of the available

`
`means for connecting computer systems to telecommunications lines for the purpose of
`
`transmitting or transferring digital signals. For instance, telephone—based modems could
`
`accomplish this. Such means could be used at the originating computer (for transmitting) and at
`
`the destination computer (for receiving), 2'. e. , the first party control unit and second party control
`
`unit, respectively.
`
`44.
`
`Figure 1 and the related text in both the ‘440 and ‘734 patents, for instance, shows
`
`that the first party control unit 20 (and its components 20A—C, 10)) and the second party control
`
`unit 50 (and its components (SOA—D, 60)) are connected via telecommunications lines.
`
`‘440
`
`patent, col. 4:37-67; ‘734 patent, 001.4135-65. A person of ordinary skill in the art would
`
`recognize that this involved means, such as a telephone-based modem, for connecting the two
`
`systems, and would have no difficulty in recognizing the nature of a transmitter and receiver
`
`required to connect and transmit digital signals in the claimed system. Accordingly, the claims
`
`themselves, which recite such a transmitter and receiver, claim sufficient structure to rebut the
`
`presumption that the limitation should be analyzed as means-plus—function claim.
`
`45.
`
`Indeed, within the claimed system, it is clear that both the receiver and transmitter
`
`are connected to their respective control integrated circuit, and in turn each other through
`
`telecommunications lines. For example, both patents explain that the second party control
`
`integrated circuit 50B includes the receiver. See ‘734 patent, col. 6:61-63; ‘440 patent, col. 6:64-
`
`66. They also explain that the digital signals are transmitted to that receiver from the first
`
`memory with a transmitter. See ‘734 patent, col. 5:51-56; “440 patent, col. 5:53-57. And, this
`
`first memory is connected to the first party control integrated circuit, which is connected to the
`
`second party control integrated circuit via telecommunications lines. ‘734 patent, col. 7:17-23;
`
`‘440 patent, col. 7:20~26. As these control integrated circuits regulate the transmission of digital

`
`signals, a person of ordinary skill in the art would understand that the transmitters and receivers
`
`are connected to them.

`
`I understand that Apple makes reference to “sales-related means” as including the
`
`means or mechanism for electronic selling, charging a fee, receiving and charging a credit card,
`
`and charging an account.
`
`I also understand that this phrase should include the transferring of
`
`money electronically as part of accomplishing the sale of desired digital signals.
`
`47. With respect to these limitations, I understand Dr. Kelly fails to find a
`
`methodology for carrying out the electronic sales of desired digital signals on an appropriately
`
`configured integrated circuit in the claimed system. Kelly Decl. W674i, 99-127.
`
`I disagree.
`
`48.
`
`Figure l of the ‘440 and ‘734 patents constitute a “pictoral flow chart which may
`
`be used in carrying out the teachings of the invention for purposes of electronic sales” of digital
`
`signals.
`
`‘734 patent, col. 3:44-48; ‘440 patent, col. 3:45-49.
`
`I have been informed that a flow
`
`chart can be sufficient to describe an implementation or the steps to program a corresponding
`
`structure clearly linked to a claimed function.
`
`49.
`
`A person of ordinary skill in the art would indeed find this flow chart to further
`
`corroborate the specification passages related to how these sales—related means or mechanisms
`
`are programmed on a control integrated circuit, as specifically highlighted in SightSound’s
`
`opening brief (pp. 38-44) and responsive brief (pp. 28-29) for these sales-related limitations. See
`
`also ‘734 patent, col. 8:15—31, 7:31-52, 4:43—50; ‘440 patent, col. 8:19-35, 7:34~55, 4:45-53.
`
`50. With respect to the means or mechanism for playing digital signals, I understand
`
`Dr. Kelly and Apple to conclude that there is no methodology for implementing the function or a
`
`clear link to a structure to carry out the function. Kelly Decl. W128—134.
`
`I disagree.
`
`51.

`which is described to execute and control the commands of the user, receives playback
`
`commands from the control panel, retrieves the selected song from the hard disk, stores a replica
`
`into memory at a high transfer rate, then sends the electronic output to speakers at a controlled
`
`rate using that memory as a temporary staging area for playback.

`
`patents, which is described as a “pictoral flow chart which may be used in carrying out the
`
`teachings of this invention for purposes of’ playback of digital signals, indicates the interaction
`
`and relationship between the various components for playback as described.

`‘734 patent, col.
`
`3:49-52; ‘440 patent, col. 3:50-53.
`
`I have been informed that this type of disclosure has been
`
`found sufficient to constitute disclosure of a specific methodology to perform a claimed function.
`
`52.
`
`A person of ordinary skill in the art would understand that these disclosures
`
`describe a clear link to a control integrated circuit to perform the playback of desired digital
`
`signals consistent with the described methodology or algorithm.
`
`I declare under penalty of perjury of the laws of the Commonwealth of Pennsylvania and
`
`the United States that the foregoing is true and correct. Executed on this 28th day of September,
`
