`INTRODUCTION
`Patent Owner IPT admits Pirim PCT discloses every limitation of claim 22
`
`except for element 22[b], “an input multiplexer adapted to receive data describing
`
`one or more parameters of the event being detected . . .” IPT also admits that
`
`Pirim PCT discloses an input multiplexer that receives data describing at least one
`
`parameter (“data (V)”) of the event being detected. IPT, thus, admits that claim 22
`
`is fully disclosed by the Pirim PCT, applying the plain and ordinary meaning of
`
`claim element 22[b].
`
`IPT’s only response is based on its incredible argument that the claim term
`
`“one or more” actually means “two or more” and that Pirim PCT, therefore, does
`
`not disclose claim 22. IPT’s argument is meritless. It cannot explain, especially
`
`under the broadest-reasonable-interpretation claim-construction standard it agrees
`
`applies, how “one or more” could possibly mean “two or more.” One is not the
`
`same as two, and if the claimed multiplexer were required to receive two or more
`
`parameters, the claim would have recited “two or more.” It does not; it recites
`
`“one or more.”
`
`II. ARGUMENT
`A.
`IPT Admits Pirim PCT Discloses all but one Element
`of Claim 22
`IPT’s Patent Owner Response and supporting declaration of Dr. Agouris
`
`(Ex. 2009) challenge only Pirim PCT’s disclosure of element 22[b], “an input
`
`1
`
`
`
`
`multiplexer adapted to receive data describing one or more parameters of the event
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`being detected . . .” P.O. Resp. at 22-26; Ex. 2009 (Agouris Decl.) at §§ I.5,
`
`III.A.1, III.B, III.C, III.D. Because Patent Owner does not respond to Petitioner’s
`
`application of Pirim PCT to any other element of claim 22, including 22[pre],
`
`22[a], 22[c], 22[d], 22[e], or 22[f], Petitioner’s showing that Pirim PCT discloses
`
`these limitations (Petition at 40-45, 49-51; Ex. 1002 (Hart Decl.) at ¶¶ 80-85, 94-
`
`101) should be deemed admitted. 37 CFR § 42.23(a) (“Any material fact not
`
`specifically denied may be considered admitted.”). Thus, the only issue that
`
`remains for trial is whether Pirim PCT discloses element 22[b].
`
`B.
`IPT’s Proposed Claim Construction Is Wrong
`Patent Owner urges a construction of claim element 22[b] that (1) is
`
`contradicted by the plain and ordinary meaning of the claim language, (2) reads out
`
`all of the disclosed embodiments except for one, which is instead improperly read
`
`into the claim, and (3) is not supported by the extrinsic evidence it cites. IPT’s
`
`proposed construction of claim element 22[b] is incorrect. That term should be
`
`accorded its plain and ordinary meaning, consistent with the BRI standard IPT
`
`agrees should apply.
`
`1.
`The Claim Language Contradicts IPT’s Construction
`Patent Owner’s Response relies on a unique application of claim element
`
`22[b], “an input multiplexer adapted to receive data describing one or more
`
`2
`
`
`
`
`parameters of the event being detected, and to output data describing a selected one
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`of the one or more parameters in response to a selection signal.” P.O. Resp. at 13-
`
`19. Patent Owner does not actually offer a construction of this phrase, but instead
`
`merely alleges that this language “requires that the multiplexer be capable of
`
`receiving data from multiple parameters.” Id. at 14 (emphasis added). This
`
`statement contradicts the plain meaning of “receive . . . one or more parameters,”
`
`which can be met by receiving one parameter or more than one parameter. It does
`
`not require receiving “multiple parameters,” as IPT alleges. Effectively, IPT urges
`
`the Board to narrow the scope of claim 22 by rewriting element 22[b] as follows:
`
`an input multiplexer adapted to receive data describing one two or more
`
`parameters of the event being detected, and to output data describing a
`
`selected one of the one two or more parameters in response to a
`
`selection signal.
`
`IPT cannot explain why the applicant would have used the word “one” in
`
`claim 22 if it really meant to say “two.” IPT’s proposed construction, thus, directly
`
`contradicts the claim language.
`
`In fact, this Panel previously rejected this same argument by Patent Owner
`
`IPT as applied to similar claim language in another patent by the same inventor. In
`
`IPR2017-00353, this Panel rejected IPT’s argument that the claim limitation
`
`“forming at least one histogram of the pixels in the one or more of a plurality of
`
`3
`
`
`
`
`classes in the one or more of a plurality of domains” should be construed to mean
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`“forming at least one histogram of the pixels in two or more classes that are in two
`
`or more domains” because it did not give effect to all of the terms of the claim.
`
`IPR2017-00353, Paper No. 12 at 9-10 (May 25, 2017) (emphasis added). Patent
`
`Owner’s construction should similarly be rejected here.
`
`2.
`The Specification Does Not Support IPT’s Construction
`IPT argues that the claimed multiplexer must have the form shown in Figure
`
`31a, i.e., that it must receive at least two parameters, DATA (A), DATA (B), etc.
`
`See P.O. Resp. at 15-16 (pointing to MUX (500) of Figure 31a, which receives
`
`Data (A), Data (B), Data (C), and Data (E)). The implicit claim construction IPT
`
`urges would import into claim 22 the embodiment depicted in Figure 31a. Id. The
`
`Federal Circuit has repeatedly counseled against a construction that imports
`
`limitations from an embodiment described in the specification. See, e.g., Comark
`
`Communs., Inc. v. Harris Corp., 156 F.3d 1182, 1186 (Fed. Cir. 1998)
`
`(“limitations from the specification are not to be read into the claims”).
`
`Patent Owner IPT contrasts the input multiplexer shown in Figure 3 (which
`
`is used by Petitioner to illustrate claim 22) and that of Figure 31a, arguing claim 22
`
`is directed to the embodiment of Figure 31a only. IPT justifies excluding the
`
`embodiment of Figure 3, because it is said to depict only a “passive histogram
`
`calculation unit” and not an “improved visual perception processor” including “the
`
`4
`
`
`
`
`auto-adapting, anticipation, and learning functions” that are the alleged focus of the
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`’293 Patent. P.O. Resp. at 6-7. This argument fails for at least two reasons.
`
`First, nothing in claim 22 requires the inclusion of any “auto-adapting,
`
`anticipation, and learning functions.” To the contrary, these alleged improvements
`
`are covered by other claims, such as claim 3 (reciting a “learning multiplexer”)
`
`and claim 6, requiring “means for anticipating the value of the classification
`
`criterion C.”
`
`Second, even if IPT were correct that claim 22 were directed to these
`
`“improved” embodiments, IPT’s construction would exclude not only the
`
`embodiment of Figure 3, but also nearly every other embodiment disclosed in the
`
`’293 Patent, including the “improved” embodiments with auto-adapting,
`
`anticipation, and learning functions. See, e.g., Figures 4, 12, 13d, 14, 15a, 15b, 17,
`
`25, annotated below, each of which includes only the type of input multiplexer
`
`disclosed in Figure 3 that IPT argues does not satisfy claim element 22[b].

`

`
`IPT’s proposed claim construction, which imports limitations from one
`
`embodiment and excludes essentially every other embodiment disclosed in the
`
`specification, cannot be correct. “[A] claim interpretation that excludes a preferred
`
`embodiment from the scope of the claim is rarely, if ever, correct.” On-Line
`
`Techs., Inc. v. Bodenseewerk Perkin-Elmer GmbH, 386 F.3d 1133, 1138 (Fed. Cir.
`
`2004).
`
`IPT also misapplies the doctrine of claim differentiation to argue that,
`
`because other claims recite multiplexers, the multiplexer of claim 22 must have a
`
`different scope. P.O. Resp. at 17 (acknowledging that claims 4 and 13 expressly
`
`recite the type of multiplexer described in Figure 3 for receiving one parameter
`
`(data signal) and a “counter” input). But the doctrine of claim differentiation
`
`applies to resolve ambiguity when a claim would otherwise be superfluous. “To
`
`the extent that the absence of such difference in meaning and scope would make a
`
`claim superfluous, the doctrine of claim differentiation states the presumption that
`
`the difference between claims is significant.” Tandon Corp. v. U.S. Int'l Trade
`
`Comm'n, 831 F.2d 1017, 1023 (Fed. Cir. 1987). Claim 3, from which claims 4 and
`
`9
`
`
`
`
`13 both depend, includes at least half a dozen limitations not recited by
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`independent claim 22, and IPT’s suggestion that a narrower scope for “input
`
`multiplexer” is required to differentiate claim 22 from claims 4 or 13 is frivolous.
`
`3.
`
`IPT’s Construction Is Not Supported By The Extrinsic
`Evidence
`The extrinsic evidence IPT cites for the definition of a multiplexer does not
`
`support IPT’s narrow construction. For example, the IEEE definition of
`
`multiplexer as “a device for selecting one of a number of inputs and switching its
`
`information to the output,” (P.O. Resp. at 18), simply describes the multiplexer
`
`shown in Figure 3 of the ’293 Patent, which is consistently called a “multiplexer”
`
`in the ’293 patent. See ’293 Patent Figure 3 (annotated excerpt showing that the
`
`“INIT” signal switches one of the “COUNTER” and “DATA(A)” signals to the
`
`output of multiplexer 105).
`
`Finally, IPT’s unsupported assertion that a POSA would understand the
`
`disputed claim language to mean that “the multiplexer must be capable of
`
`
`
`10
`
`
`
`
`receiving both ‘one’ or ‘more’ than one parameter” makes no sense. P.O. Resp. at
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`18-19 (emphasis added). Requiring both A or B is meaningless and grammatically
`
`improper. Evidently, IPT sees this odd linguistic construction as a more palatable
`
`way to present the ridiculous proposition that a POSA would understand “A or B”
`
`to actually mean “A and B.” Understandably, IPT includes no citation to its
`
`expert’s declaration for this bold statement.
`
`In summary, all of IPT’s arguments on claim construction essentially boil
`
`down to an assertion that “one or more” really means “two or more.” There is
`
`simply no justification for rewriting the claim as IPT argues. The phrase “an input
`
`multiplexer adapted to receive data describing one or more parameters of the event
`
`being detected, and to output data describing a selected one of the one or more
`
`parameters in response to a selection signal” should carry its plain and ordinary
`
`meaning—specifically, “one or more” means “one or more” or “at least one.” It
`
`does not mean “two or more” or “at least two.”
`
`C.
`
`IPT Admits Claim 22 Is Disclosed Under the Proper
`Construction of Element 22[b]
`Pirim PCT discloses claim 22 under the proper construction (i.e., the plain
`
`and ordinary meaning) of claim element 22[b], as described in the Petition and
`
`11
`
`
`
`
`supported by the declaration of Dr. Hart (Ex. 1002), filed concurrently therewith.1
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`See Petition at 40-45, 49-51; Ex. 1002 (Hart Decl.) ¶¶ 80-85; 94-101. In particular,
`
`in addition to disclosing claim elements 22[pre], 22[a], 22[c], 22[d], 22[e], and
`
`22[f], which Patent Owner does not challenge, Pirim PCT discloses element 22[b],
`
`“an input multiplexer adapted to receive data describing one or more parameters of
`
`the event being detected, and to output data describing a selected one of the one or
`
`more parameters in response to a selection signal.” For example, Figure 14 of
`
`Pirim PCT (annotated below) discloses an input multiplexer (104) (shaded green)
`
`that receives data describing one or more parameters of the event being detected (at
`
`least parameter “data (v)”) and to output data describing a selected one of the one
`
`or more parameters (Mux 104 outputs “data (v)”) in response to a selection signal
`
`(“init”).
`
`
`1 Patent Owner mischaracterizes the District Court’s Claim Construction Order,
`alleging it “construed” the term “configured to determine the data in the histogram
`. . .” P.O. Resp. at 2 n1. In fact, the Order did not construe that term but rather
`found claim 22 invalid as indefinite, i.e., incapable of being construed. Petitioner
`did not raise that argument here, as indefiniteness is not a ground for institution of
`inter partes review. But if Patent Owner is arguing for the same “construction”
`found by the District Court, claim 22 is invalid as indefinite.

`Petitioner’s Reply
`
`
`
`Critically, IPT does not dispute that element 22[b] is disclosed by Pirim
`
`PCT under the plain and ordinary meaning of this limitation. To the contrary, IPT
`
`repeatedly admits that Pirim PCT discloses a multiplexer adapted to receive one
`
`parameter of the event being detected, and to output that parameter in response to a
`
`selection signal:
`
`13
`
`
`
`
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`each multiplexer of Pirim relies on a binary signal to determine
`
`whether the single parameter data is passed to the histogram unit or
`
`instead whether a “counter” or “zero” signal is passed.
`
`P.O. Resp. at 2.
`
`Patent Owner attempts to distinguish Pirim PCT, arguing that when the
`
`“init” signal is set to one, it is the “counter” signal that is selected and not “data
`
`(v)” so “MUX 104 does not disclose selecting ‘one of the one or more parameters,’
`
`either in response to a ‘selection signal’ or otherwise.” P.O. Resp. at 23-24. This
`
`argument is frivolous because when the “init” signal is set to its other state, zero,
`
`the “data (v)” input is selected, as Pirim PCT describes: “the init line is set to zero,
`
`which . . . in the case of multiplexor 104 results in data from the spatial processing
`
`unit 117, i.e., the V data, being sent to the Address line of memory 100.” Ex. 1005
`
`(Pirim PCT) at 29.2 Thus, the “init” signal selects either the “data (v)” or
`
`“counter” input of MUX 104 to be sent to its output, depending on whether “init”
`
`is set to zero or one, respectively, and it is thus the claimed “selection signal.”
`
`Further, Patent Owner’s own expert agrees with Petitioner and admits that
`
`the “init” signal controls which input of multiplexer 104 is routed to the output:
`
`
`2 Citations to Ex. 1005 (Pirim PCT) refer to the page numbers added by Petitioner
`in the lower right corner of the exhibit.

`
`
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`Pirim’s multiplexers 102 and 104 (yellow) both take only “init” (green)
`
`as the control signal to determine which of the two output signal (blue)
`
`to output. . . . The two possible input data signals for multiplexer 104
`
`are data(V), i.e., the “V” or velocity parameter data, and the Counter
`
`signal, which is used to reset the histogram memory.
`
`Ex. 2009 (Agouris Decl.) at §§III.C.39-40.
`
`In addition, neither the Patent Owner nor Dr. Agouris ever suggests that
`
`Pirim PCT’s “data (V)” is not a “parameter” as recited by claim 22. Indeed, Dr.
`
`Agouris expressly refers to “data (V)” as “velocity parameter data.” Ex. 2009
`
`(Agouris Decl.) at § III.C.40. Thus, Dr. Agouris admits that Pirim PCT discloses
`
`claim 22 under the proper (plain meaning) construction of element 22[b].
`
`D. Claim 22 Is Obvious In Light of Pirim PCT, Even
`under IPT’s Erroneous Construction
`Even if IPT were correct that “one or more” means “two or more”—it does
`
`not—Pirim PCT would still render claim 22 obvious. For example, it would have
`
`been obvious to use the same type of multiplexer (104) disclosed in Figure 14 of
`
`Pirim PCT to switch between two “data” parameters, such as speed “V” and
`
`direction “DI.” See, e.g., Ex. 1005 (Pirim PCT) at 24-25 (noting that “V”
`
`represents pixel speed in the range 0 - 7 and “DI” represents direction of pixel
`
`displacement, also in the range of 0 - 7). Doing so would enable the system to
`
`15
`
`
`
`
`time-share one histogram calculation unit, reducing the amount of hardware
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`required. Such a proposed modification of the embodiment of Figure 14 is
`
`illustrated in the excerpt below:
`
`
`
`In this proposed modification a new mux (in yellow) is added upstream of
`
`the existing mux 104 and used to select which of the “V” and “DI” parameters will
`
`be processed by this histogram unit, thereby allowing one histogram unit to be
`
`used for processing two parameters. It would have been obvious to make such a
`
`modification because the added mux would operate in exactly the same way as the
`
`existing mux (switching one of two inputs to the output) and would enable a
`
`reduction in the number of hardware components or logic gates by time-sharing a
`
`histogram unit.
`
`16
`
`
`
`IPT asserts that such a modification to Pirim PCT is not possible because
`
`IPR2017-00336 (U.S. 6,989,293)
`Petitioner’s Reply
`
`
`
`Pirim PCT’s histogram units are all different, with each only capable of treating a
`
`single parameter. P.O. Resp. at 25 (arguing that a classifier for the speed
`
`histogram unit would have only eight registers while the luminance histogram unit
`
`would require 256). But this argument is contradicted by Pirim PCT, which
`
`expressly discloses that all of the histogram units are identical: “In general, each of
`
`the histogram formation blocks 24-29 is identical to the others and functions in the
`
`same manner.” Ex. 1005 (Prim PCT) at 28. Furthermore, in the exemplary
`
`modification shown above, both speed “V” and direction “DI” are represented by
`
`integers 0 - 7 and, thus, both use classifiers with eight registers. Ex. 1005 (Pirim
`
`PCT) at 30 (noting that both the classifier associated with histogram formation
`
`block 25 (V) and the classifier associated with histogram formation block 26 (DI)
`
`have eight registers). IPT is simply wrong that one histogram formation block of
`
`Pirim PCT could not be used to process two different data parameters selected
`
`using a multiplexer like multiplexer 104 shown in Figure 14 of Pirim PCT.
`
`Thus, Pirim PCT anticipates or renders obvious claim 22, not only under the
`
`correct construction of the claim language, but also under the incorrect
`
`construction offered by Patent Owner.

`Petitioner’s Reply
`
`III. CONCLUSION
`For the reasons set forth above, the Board should find that claim 22 of the
`
`’293 Patent is invalid as anticipated or obvious in light of Pirim PCT.
