`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`Introduction
`I.
`
`Neither Petitioner’s (“Qualcomm’s”) original Petition evidence nor the new
`
`Reply evidence demonstrate that U.S. Patent No. 5,600,605 to Schaefer (“Schaefer”)
`
`discloses a memory that provides a non-interruptible burst, as required by all
`
`challenged claims of U.S. Patent No. 6,651,134 (“the ’134 Patent”- Ex-1001).
`
`Even Mr. Murphy, Qualcomm’s expert, admits that Schaefer discloses
`
`interrupting bursts before a burst has been completed using a variety of burst
`
`termination options. For example, Mr. Murphy admitted that Schaefer discloses a
`
`BURST TERMINATE command, a PRECHARGE command, or a new READ or
`
`WRITE command. See e.g., Ex-2009, 118:14-22.
`
`Because Qualcomm cannot dispute Schaefer’s explicit teaching of multiple
`
`options for interrupting a burst before completion, Qualcomm instead manufactures
`
`a scenario based on Schaefer’s AUTO-PRECHARGE command according to which
`
`Schaefer prevents interruptions of a burst during the entire length of the burst.
`
`But, as was explained in the Patent Owner’s Response (“POR”) and is further
`
`explained herein, Qualcomm continues to misread or mischaracterize Schaefer,
`
`which discloses prohibiting user commands only during the time necessary to
`
`perform and complete a precharge operation and to argue that the prohibition on
`
`issuing user commands applies to the entire burst transfers as well. But Schaefer’s
`
`disclosure is clear—and Qualcomm runs away from it. Schaefer explicitly defines
`
`1
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`when the precharge operation is initiated and until when the used is prohibited from
`
`issuing another command, i.e., until the precharge time is completed:
`
`The AUTO-PRECHARGE command insures that the precharge is
`initiated at the earliest, valid stage within a burst cycle. The user is not
`allowed to issue another command until the precharged time (tRP) is
`completed.
`Ex-1017, 7:40-44.
`
`That is, the prohibition of issuing another command is limited to the
`
`precharged time (tRP). Accordingly, before the precharge has been initiated, the user
`
`can issue another command, which would interrupt the existing burst. Neither
`
`Qualcomm nor Mr. Murphy dispute that the issuance of another command would
`
`interrupt the existing burst. Because Qualcomm cannot get away from this reality,
`
`the Reply resorts in mischaracterizations of Monterey’s arguments, Dr. Brogioli’s
`
`testimony, and Schaefer’s disclosures, in an apparent attempt to create distraction
`
`and confusion. But these attempts cannot and should not derail the focus from
`
`Schaefer’s explicit disclosure that bursts are interruptible, except only during
`
`precharge.
`
`II.
`
`Schaefer Does Not Disclose “Wherein Said Generation Of Said
`Predetermined Number Of Internal Address Signals Is Non-
`interruptible”
`
`Schaefer does not disclose the “wherein said generation of said predetermined
`
`number of internal address signals is non-interruptible” limitation recited by
`
`2
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`independent claims 1, 16, and 17, and incorporated by challenged dependent claims
`
`2-5, 7, 9-10, 12-18, 20, and 21. Particularly, Schaefer (1) explicitly discloses
`
`interrupting bursts using a variety of burst termination options (see POR, 30-32);
`
`and (2) Schaefer’s alleged prohibition on user commands, according to Schaefer’s
`
`disclosure and Qualcomm’s expert’s deposition admissions, applies only to the
`
`PRECHARGE command operation period tRP. (See POR, 36-52.)
`
`A.
`
`Schaefer Prohibition On User Commands During The
`PRECHARGE Command Operation Period Does Not Disclose
`Non-Interruptibility Of Bursts
`Petitioner mischaracterizes the POR and incorrectly alleges that “[t]he parties
`
`agree that Schaefer’s language ‘[t]he user is not allowed to issue another command
`
`until the precharged time (tRP) is completed’ (EX1017, 7:42-44) conveys non-
`
`interruptibility.” Reply, 7 (emphasis in original, emphasis added).
`
`The POR instead made clear that Schaefer conveys interrupting bursts by
`
`disclosing multiple means for interrupting bursts before completion because, as
`
`Qualcomm’s expert admitted, Schaefer is directed to interrupting bursts, which
`
`result in advantages, such as preventing wasted cycles in between bursts. See, POR,
`
`29-34.
`
`Petitioner suggests that prohibiting issuing another command during a
`
`portion of a burst conveys non-interruptibility. Petitioner is mistaken. This
`
`argument is equivalent to arguing that a flight between Los Angeles and New York
`
`3
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`with a layover in Dallas is a direct flight, just because the Dallas-New York leg of
`
`the trip is a direct flight. The fact that Schaefer discloses prohibiting issuing another
`
`command only during the PRECHARGE time (tRP) conveys actually that before the
`
`PRECHARGE time, issuing another command was allowed, which would interrupt
`
`the burst.
`
`B.
`
`Schaefer’s Plain Language Is Clear That Issuing Another
`Command Is Only Prohibited During The PRECHARGE Time
`(tRP)
`
`Qualcomm accurately identifies the dispute between the parties:
`
`The only dispute between the parties is whether this prohibition is
`limited to “during tRP,” as PO asserts, or from the issuance of the user
`command at T2, as Petitioner asserts. That is, PO asserts that the
`prohibition is limited to the time highlighted in green below, while
`Petitioner asserts the prohibition begins when the user issues the burst
`command at T2.
`Reply, 7.
`
`4
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`
`
`Citing to Schaefer at 7:38-44, Qualcomm notes that “[t]he plain language of
`
`Schaefer states that when ‘using the AUTO-PRECHARGE command feature,’ ‘[t]he
`
`user is not allowed to issue another command until the precharged time (tRP) is
`
`completed.’” Based on this, Qualcomm alleges that “[t]he language and syntax of
`
`this passage describe a period beginning at T2. The passage references tRP solely
`
`in defining the end of the prohibition period, using the term ‘until,’ not ‘during.’”
`
`Reply, 8.
`
`Qualcomm mischaracterizes Schaefer. Even though Qualcomm cites
`
`Schaefer at 7:38-44, Qualcomm conveniently only mentions the sentence (Ex-1017,
`
`42-44) that only references the end of the prohibition period. Qualcomm attempts
`
`5
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`to hide the previous sentence that defines the start of the prohibition period. For
`
`clarity and for illustrating Qualcomm’s disingenuous attempt to distort Schaefer’s
`
`disclosure, Patent Owner provides the entire relevant section of Schaefer:
`
`By using the AUTO-PRECHARGE command feature, a manual
`PRECHARGE command does not need to be issued during the
`functional operation of SDRAM 20. The AUTO-PRECHARGE
`command insures that the precharge is initiated at the earliest, valid
`stage within a burst cycle. The user is not allowed to issue another
`command until the precharged time (tRP) is completed.
`Ex-1017, 7:38-44.
`
`The passage clearly references when the precharge is initiated (“at the earlier
`
`valid stage within a burst cycle” (Ex-1017, 7:42)) until it is completed. Therefore,
`
`when the AUTO-PRECHARGE command is employed, i.e., in the event that the
`
`AUTO-PRECHARGE command is employed, a POSITA would have understood
`
`that the “user is not allowed to issue another command” from the “earliest, valid
`
`stage within a burst cycle” “until the precharged time (tRP) is completed.”
`
`Qualcomm further mischaracterizes the POR, by alleging that “PO offers no
`
`direct rebuttal to this passage, but instead cites to later passages.” Reply, 9 (citing
`
`POR, 44-45.) Qualcomm conveniently omits the discussion in the POR about “the
`
`AUTO-PRECHARGE command insur[ing] that the precharge is initiated at the
`
`earliest, valid stage within a burst cycle.’” POR, 43 (citing Ex-1017, 7:41-43.)
`
`Based on Dr. Brogioli’s explanation, the POR concludes that “Schaefer must ensure
`
`6
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`that a subsequent early ACTIVE command does not interrupt the precharge
`
`operation.” POR, 44. Accordingly, the POR clearly identified the starting and
`
`ending time, i.e., the precharge time (tRP), of the prohibition of issuing another
`
`command.
`
`Qualcomm also notes that “Dr. Brogioli concedes that the only user (external)
`
`command shown in FIG. 4 from T2 through T9 is the READ with AUTO-
`
`PRECHARGE issued at T2.” But Figure 4 of Schaefer is not an example of a
`
`burst that is interrupted. Qualcomm’s logical fallacy is generalizing that Schaefer
`
`does not disclose interrupting bursts just because in the particular example of Figure
`
`4 another command is not issued between T3 and T6. But the issue is not whether
`
`in the particular example of Figure 4 another command is issued. Rather, the issue
`
`is whether another command can be issued between T2 and T6. The answer is yes.
`
`PO’s Interpretation Is Consistent with Schaefer’s Plain Language
`
`C.
`Qualcomm also argues that “[a] POSITA would not interpret Schaefer’s
`
`language, as PO urges, to permit user interrupts from T2 to T6 in a fixed length
`
`READ with AUTO-PRECHARGE burst not only because it is contrary to the plain
`
`language but also because the proposed configuration makes little sense.” Reply, 9.
`
`First, as explained above in Section III.B, Schaefer’s plain language is clear that
`
`issuing another command is only prohibited during the PRECHARGE time (tRP).
`
`Second, for the argument that PO’s “proposed configuration [allegedly] makes little
`
`7
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`sense” (Reply, 9), Qualcomm points to Mr. Murphy’s declaration at paragraph 83
`
`where “Mr. Murphy explains that ‘there are reasons Schaefer did not propose’
`
`permitting interrupts from T2 to T6, including that ‘[a]llowing such interrupts would
`
`have been more costly (more circuitry) and may have detrimentally impacted the
`
`speed of operation.’” Reply, 9 (citing Ex-1015, ¶83).
`
`Mr. Murphy merely offers a conclusory statement without providing any
`
`justification that would support such conclusion. Mr. Murphy alleges that “such
`
`interrupts would have been more costly (more circuitry).” Ex-1015, ¶83. But Mr.
`
`Murphy does not explain how and why allowing interrupting bursts would have been
`
`more costly or would have involved more circuitry. Mr. Murphy merely ponders
`
`“[t]he question always ends up being asked, what is the advantage to this change vs.
`
`the cost and how often will it be used?” Id. But PO’s interpretation would cause
`
`neither additional costs nor additional circuitry. This is because Schaefer already
`
`includes circuitry for interrupting bursts, as Mr. Murphy acknowledged:
`
`Q. Schaefer discloses at least three ways to terminate a burst, burst
`termination command, a precharge command or a second burst
`operation; correct?
`A. That’s correct, for the bursts that don't include an auto-precharge.”
`Ex-2009, 118:14-22.
`
`And as discussed in detail in Section III.D below, the AUTO-PRECHARGE
`
`command is merely a command that performs all of the same precharge functions
`
`8
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`described for the PRECHARGE command, without having
`
`to issue
`
`the
`
`PRECHARGE command manually.
`
`Besides, as Mr. Murphy further acknowledged, Schaefer explicitly teaches
`
`that allowing interrupting bursts is beneficial:
`
`Q. So one reason to allow interruptions of burst is to avoid wasting
`
`cycles within the device; correct?
`
`A. That's correct.
`
`Ex-2009, 94:25-95:4.
`
`Mr. Murphy also alleged that “[a]llowing such interrupts … and may have
`
`detrimentally impacted the speed of operation.” Reply, 9. Mr. Murphy does not
`
`even offer a definitive answer as to whether there will be a detrimental impact to the
`
`speed of operation. Such a wavering opinion should be given no weight. Mr.
`
`Murphy’s inability to definitely conclude whether there will be a detrimental impact
`
`to the speed of operation undermines Qualcomm’s argument.
`
`Qualcomm also alleges that “[d]esigning burst with AUTO-PRECHARGE
`
`operations to also permit interrupts would provide no additional functionality and
`
`would have numerous downsides.” Reply, 10. For support, Qualcomm points to
`
`Mr. Murphy’s declaration at paragraph 83, where Mr. Murphy concludes that
`
`“[a]llowing such interrupts would have been more costly (more circuitry) and may
`
`have detrimentally impacted the speed of operation.” Reply, 10 (citing to Ex-1015,
`
`9
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`¶83.) As discussed above, such conclusory and wavering opinion should be given
`
`no weight.
`
`For additional support Qualcomm also alleges that “allowing interrupts before
`
`the internal PRECHARGE operation automatically begins would negate the stated
`
`advantage of AUTO-PRECHARGE.” Reply, 10. Qualcomm points to Schaefer and
`
`notes that “‘[b]y using the AUTO-PRECHARGE command feature, a manual
`
`PRECHARGE command does not need to be issued’ and, instead, ‘the precharge is
`
`initiated at the earliest, valid stage within a burst cycle.’” Reply, 10 (citing Ex-1017,
`
`7:38-43.). Qualcomm concludes that “[i]f such a burst were terminated prior to that
`
`‘earliest, valid stage with a burst cycle,’ which Schaefer explains is after the reads
`
`or writes are complete, then the benefit of AUTO-PRECHARGE would not be
`
`obtained.” Reply, 10 (internal citations omitted.)
`
`Qualcomm is mistaken. Qualcomm misrepresents Schaefer. Further,
`
`Qualcomm’s conclusion is even contrary to Qualcomm’s expert admissions.
`
`Qualcomm attempts to associate Schaefer’s advantages of interrupting bursts, with
`
`the benefit conveyed by the AUTO-PRECHARGE command. Qualcomm’s attempt
`
`fails. As the POR explained “because the PRECHARGE and ACTIVE command
`
`operations (1) must be completed before beginning a READ or WRITE burst
`
`operation, and (2) require a given number of cycles to complete, ‘[a]t many
`
`frequencies, the time to perform the PRECHARGE command operation, and the
`
`10
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`ACTIVE command operation results in wasted time which adds up to an extra clock
`
`cycle resulting in a wait cycle.’” POR, 17-18 (citing Ex-1017, 1:49-52.)
`
`Specifically, as the POR further explained, “at some frequencies, ‘the total
`
`time required for tRP and tRCD equals an extra clock cycle or system clock cycle time
`
`(tCK) than if the two (tRP and tRCD) were able to be accomplished as a single parameter
`
`thereby resulting in a wait cycle.’” POR, 18 (citing Ex-1017, 9:11-15.) Accordingly,
`
`the wasted cycles in Schaefer occur as a result of the “the total time required for tRP
`
`and tRCD.” Figure 4 of Schaefer, which illustrates an example of the AUTO-
`
`PRECHARGE command, shows that tRP and tRCD run consecutively, i.e., tRP runs
`
`between T6 and T9, while tRCD starts running at T9.
`
`
`
`11
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`Ex-1017, Fig. 4 (annotated by Qualcomm and further annotated by Monterey.)
`
`Therefore, since the wasted cycles in Schaefer occur as a result of the “the
`
`total time required for tRP and tRCD” the start time of the precharge time (tRP) is
`
`irrelevant to the overhead (wasted cycles) that Schaefer is trying to eliminate.
`
`Mr. Murphy agrees that the wasted clock cycles in Schaefer are a result of
`
`performing—not the starting time of—the precharge and active commands:
`
`Q. Schaefer is directed to eliminating the potential wasted clock cycles
`necessary to perform the precharge command operations and the active
`command operations; correct?
`A. Yes, given the fact that the frequencies of operation can be different.
`Ex-2009, 110:19-111:1.
`
`Consequently, interrupting bursts avoids wasting cycles that is a result of
`
`performing the precharge and active commands, as Mr. Murphy admitted:
`
`Q. So one reason to allow interruptions of burst is to avoid wasting
`cycles within the device; correct?
`A. That's correct.
`Ex-2009, 94:25-95:4.
`
`Accordingly, Qualcomm’s argument about initiating the precharge “at the
`
`earliest valid stage within a burst cycle” (Reply, 10) is a mischaracterization of
`
`Schafer and a failed attempt to create confusion.
`
`12
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`D. A POSITA Would Have Understood Schaefer’s Disclosure Of
`Circuitry For Reducing Time Between Bursts To Apply to The
`AUTO-PRECHARGE Command
`
`Qualcomm further alleges that “Schaefer’s separate disclosure of circuitry for
`
`reducing time between bursts sheds no light on how a POSITA would interpret
`
`Schaefer’s unrelated disclosure of a fixed length burst with AUTO-PRECHARGE.”
`
`Reply, 11. Qualcomm is mistaken.
`
`Qualcomm and Mr. Murphy tries to create a distance between the
`
`“PRECHARGE” and the “AUTO-PRECHARGE” commands. For example, Mr.
`
`Murphy testified:
`
`Q. Schaefer discloses at least three ways to terminate a burst, burst
`termination command, a precharge command or a second burst
`operation; correct?
`A. That’s correct, for the bursts that don't include an auto-precharge.
`Ex-2009, 118:14-22.
`
`But a POSITA would have understood that Schaefer treats “PRECHARGE”
`
`“AUTO-PRECHARGE” in a similar manner. For example, Schaefer discloses that
`
`“[a]n AUTO-PRECHARGE command is a non-persistent feature in SDRAM 20
`
`which performs all of the same individual bank precharge functions described
`
`above for the PRECHARGE command.” Ex-1017, 7:29-32. Schaefer describes
`
`the difference between the two commands as not having to issue a manual
`
`PRECHARGE command. See id., 7:38-40 (“By using the AUTO-PRECHARGE
`
`13
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`command feature, a manual PRECHARGE command does not need to be issued
`
`during the functional operation of SDRAM 20.”)
`
`Therefore, a POSITA would not have understood the lack of explicit
`
`disclosure in Schaefer of a burst termination for bursts that include AUTO-
`
`PRECHARGE as distinguishing the bursts with manual PRECHARGE and AUTO-
`
`PRECHARGE. Rather, a POSITA would have understood the AUTO-
`
`PRECHARGE “perform[ing] all of the same individual bank precharge functions
`
`described above for the PRECHARGE command” to suggest that that bursts with
`
`either the manual PRECHARGE or the AUTO-PRECHARGE could be terminated.
`
`Qualcomm also alleges that:
`
`The portion of Schaefer the POR quotes begins with “[i]n either a
`READ command or WRITE command with either a PRECHARGE
`command [i.e., without AUTO-PRECHARGE] or an AUTO-
`PRECHARGE command …,” making clear this passage says nothing
`specific to AUTO-PRECHARGE functionality.
`Reply, 11-12.
`
`But this conclusory statement is another attempt by Qualcomm to
`
`mischaracterize Schaefer and the POR. Qualcomm again hides the disclosure of
`
`Schaefer that was discussed in the POR that contradicts Qualcomm’s argument. The
`
`entire portion of Schaefer identified in the POR recites:
`
`[I]n ‘either a READ command or WRITE command with either a
`PRECHARGE command or an AUTO-PRECHARGE command
`
`14
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`following the READ or WRITE command, the above-described
`problem of too much total time between the addition of tRP and tRCD may
`result an initial wait cycle.’
`POR, 33 (citing Ex-1017, 9:16-21.)
`
`Schaefer, therefore, makes it clear that both the manual PRECHARGE and
`
`AUTO-PRECHARGE commands may result in an initial wait cycle, which is a
`
`wasted cycle. And Mr. Murphy agreed that Schaefer is directed to eliminating
`
`wasted clock cycles:
`
`Q Schaefer is directed to eliminating wasted clock cycles between reads
`and writes in an SDRAM where a precharge is necessary; correct?
`A Yes.
`
`Ex-2009, 112:3-8.

`
`Schaefer Discloses Burst Termination Commands For a Fixed-
`Length Burst With AUTO-PRECHARGE.
`Qualcomm finally alleges that Schaefer does not disclose “burst termination
`
`commands for a fixed-length burst with AUTO-PRECHARGE.” Reply, 12.
`
`Qualcomm is mistaken. First, Qualcomm mischaracterizes Schaefer by alleging that
`
`a “full page” burst command is “not fixed.” See, Reply, 12 (“[U]ser interrupt
`
`commands in the specific context of a “full page” (not fixed) burst…”.); id., (“And,
`
`as discussed below, the differences between “full page” and “fixed length” bursts
`
`further contradict an assumption that Schaefer’s passages would apply to all burst
`
`types.”)
`
`15
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`Schaefer in contrast defines a “full page” burst as a fixed-burst of 1024
`
`cycles. See, Ex-1017, 6:1-2. (“Burst lengths of 2, 4, 8, or full page (1,024) cycles
`
`are programmable into mode register…”) The “full page” burst however, “will wrap
`
`around and continually restart the ‘burst’ operation” until it is stopped by one of
`
`the burst interruption options. (Ex-1017, 5:15-16) That is a full page burst is better
`
`understood as consecutive fixed-burst operations, each having 1024 cycles,
`
`instead of a not-fixed burst, as Qualcomm appears to suggest. Accordingly, the
`
`premise of Qualcomm’s argument in Section III.E of the Reply is incorrect, and
`
`therefore the arguments in Section III.E should be disregarded.
`
`Qualcomm also alleges that Dr. Brogioli admits that Schaefer does not
`
`disclose “burst termination commands for a fixed-length burst with AUTO-
`
`PRECHARGE.” Reply, 12. For support, the Reply cites—but not quotes—Dr.
`
`Brogioli’s testimony at Ex-1029, 34:8-23, 36:5-37:12, 38:17-39:8. These sections
`
`do not support Qualcomm’s argument. In fact they contradict it. Specifically, in the
`
`sections identified by Qualcomm, Dr. Brogioli confirmed that (i) a full-page burst
`
`would wrap around and continuously restart until getting interrupted (see e.g., Ex-
`
`1029, 36:19-25. (“The full-page burst…will wrap around and restart…until a burst
`
`termination command or precharge command is indicated by the command
`
`controller, or until interrupted with another burst operation.”) and (ii) 2-4-8 cycles
`
`long bursts do not wrap around (loop) or restart, but—similar to the fixed “full-
`
`16
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`page” burst—can also be interrupted (see e.g., Ex-1029, 36:16-18. (“I would say
`
`that the burst length of 2, 4, or 8 in Schaefer will ultimately conclude on their own,
`
`if allowed, you know, to run to completion.”)
`
`Dr. Brogioli also confirmed that Schaefer does not explicitly discuss an
`
`example of a fixed “full-page” burst with AUTO-PRECHARGE. But Schaefer
`
`needs not discuss and provide examples of all possible permutations of the 4-type of
`
`fixed bursts (i.e., 2, 4, 8, or full page (1,024) cycles) or unfixed bursts with AUTO-
`
`PRECHARGE to explain how fixed bursts in Schaefer are interrupted. For lack of
`
`actual arguments, Qualcomm attempts to manufacture new (non-existent) disputes.
`
`And in any case, Mr. Murphy admitted that Schaefer discloses at least three
`
`ways to terminate the bursts disclosed in Schaefer:
`
`Q. Schaefer discloses at least three ways to terminate a burst, a burst
`termination command, a precharge command or a second burst
`operation; correct?
`A. That's correct, for the bursts that don't include an auto-precharge.
`Ex-2009, 118:15-22.
`
`Notwithstanding his objection in the case of an AUTO-PRECHARGE
`command, Mr. Murphy agreed that bursts can be interrupted. But as already
`explained above the AUTO-PRECHARGE command performs all the
`PRECHARGE functions, without having to issue a manual PRECHARGE
`command.

`Fixed Length Bursts of 2, 4, And 8 Cycles Can Be Interrupted
`1.
`Qualcomm argues that fixed length bursts of 2, 4, and 8 cycles can “conclude
`
`on their own without need for an additional external user command.” Reply, 13.
`
`But the fact that a burst can conclude “on its own” without being interrupted, does
`
`not make it “uninterruptible” as the claims of the ’134 Patent require. As Dr.
`
`Brogioli explained, bursts of length of 2, 4, and 8 cycles can get interrupted, i.e.,
`
`may not be allowed to run to completion. See Ex-1029, 36:16-18 (“I would say that
`
`the burst length of 2, 4, or 8 in Schaefer will ultimately conclude on their own, if
`
`allowed, you know, to run to completion.”)
`
`2. Mr. Murphy Admitted That Fixed Bursts Without AUTO-
`PRECHARGE Can Be Terminated
`Qualcomm does not dispute that Mr. Murphy admitted that fixed bursts
`
`without AUTO-PRECHARGE can be terminated. Qualcomm confirms that:
`
`Mr. Murphy agreed that burst termination commands would apply only
`“for the bursts that don’t include an auto-precharge.” EX2009, 118:14-
`22. The only relevant question here is whether Schaefer’s disclosure of
`user interrupt commands apply to a fixed length burst with AUTO-
`PRECHARGE.
`Reply, 14.
`
`And as explained in the POR and herein, Schaefer’s disclosure is clear that
`
`fixed length bursts with AUTO-PRECHARGE can be interrupted before the
`
`precharge operation has been initiated.

`III. Mr. Murphy’s Declaration Should Be Given Little Or No Weight
`Monterey explained in the POR why the Board should afford little or no
`
`weight to Mr. Murphy’s declaration. See POR, 23-28. Qualcomm spends three
`
`pages in their Reply on this issue (see Reply, 4-6), but never actually addresses
`
`Monterey’s argument. Specifically, neither Qualcomm in their Reply nor Mr.
`
`Murphy at his deposition provided a reasonable explanation about Mr. Murphy’s
`
`conflicting testimony.
`
`Qualcomm instead tried to divert the Board’s focus on the matter by listing
`
`Mr. Murphy’s experience. But an expert’s experience–any expert’s experience–is
`
`irrelevant to the expert’s credibility, if the expert provides conflicting testimony on
`
`an identical issue. Accordingly, the Board should significantly discount Mr.
`
`Murphy’s credibility. See, e.g., UltraTec, Inc. v. CaptionCall, LLC, 872 F.3d 1267,
`
`1273 (Fed. Cir. 2017) (“If [an expert] gave conflicting testimony on cross-
`
`examination, this would be highly relevant to both the Board’s analysis of the
`
`specific issues on which he gave inconsistent testimony and to the Board’s overall
`
`view of his credibility.”).
`
`A. Dr. Brogioli Was A POSITA At The Time Of Filing Of The ’134
`Patent
`
`There is no dispute between the parties about the definition of a person of
`
`ordinary skill in the art (POSITA) in this proceeding. Both Parties have agreed that
`
`a POSITA “would have had at least a degree in electrical or computer engineering,
`
`19
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`and at least two years of experience in design, development, and/or testing of
`
`memory circuits, related hardware design, or the equivalent, with additional
`
`education substituting for experience and vice versa.” Pet., 14; POR, 21.
`
`There is also no dispute that Dr. Brogioli satisfied this definition as of
`
`February 14, 2000—the filing date of the ’134 Patent. Specifically, Dr. Brogioli was
`
`awarded a Bachelor of Science degree in Electrical Engineering in 1999 from the
`
`Rensselaer Polytechnic Institute. See, Ex-2007, 1. Dr. Brogioli had at least five
`
`years of experience in design, development, and/or testing of memory circuits,
`
`related hardware design, or the equivalent, as of the filing date of the ’134 Patent.
`
`See, id., 3.
`
`To distract the Board’s attention from Qualcomm’s expert conflicting
`
`testimony, Qualcomm alleges that Dr. Brogioli “was not a POSITA at the time of
`
`filing of the ’134 Patent,” under a new definition of the POSITA level. Reply, 6.
`
`But when Qualcomm deposed Dr. Brogioli, Qualcomm asked Dr. Brogioli
`
`about his experience, his credentials, and his areas of expertise. Qualcomm did
`
`not—and could not cast any doubt about Dr. Brogioli’s ability to provide expert
`
`testimony in this matter.
`
`IV. Conclusion
`For the foregoing reasons, Qualcomm has failed to carry its burden of proving
`
`that the challenged claims are anticipated or obvious. Accordingly, Monterey
`
`20
`
`
`
`Case IPR2020-01492
`U.S. Patent No. 6,651,134
`respectfully requests a final written decision affirming the patentability of each of
`
`the challenged claims.
