`
`INTRODUCTION
`
`Patent Owner TQ Delta, LLC (“Patent Owner”) submits this Response under
`
`37 CFR §42.120 to the Petition filed by Cisco, Inc. requesting inter partes review
`
`of claims 1-6 of U.S. Pat. No. 7,835,430 (“the ’430 patent”). Dish Network LLC
`
`joined this proceeding pursuant to an order in 2017-00251 (Paper 10). Also
`
`pending in IPR2017-00420 is a Motion for Joinder to this proceeding filed by
`
`Comcast Cable Communications (which Patent Owner does not oppose); that
`
`Motion does not have a ruling.
`
`The Board has instituted inter partes review in this proceeding based on a
`
`single Ground—alleged obviousness in view of a combination of Milbrandt,
`
`Chang, Hwang, and ANSI T1.413. Patent Owner, however, respectfully submits
`
`that for purposes of institution (1) the Board misapprehended or overlooked Patent
`
`Owner’s rebuttal arguments on non-obviousness and the controlling law with
`
`respect to those arguments, and (2) the Board accepted as true several unsupported
`
`factual statements by Petitioner’s expert that are wholly incorrect and contradicted
`
`by the asserted references themselves. Indeed, as shown by his testimony at his
`
`deposition, Petitioners’ expert (Dr. Kiaei) is unknowledgeable and unqualified
`
`regarding the technical issues in this proceeding. Therefore, Patent Owner
`
`provides additional detail, technical explanations from its own qualified expert (Dr.
`
`Chrissan), and further legal support to clarify these issues.
`
`
`
`1
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`First, the Board misapprehended one of Patent Owner’s arguments as to
`
`why it would not have been obvious to combine Chang’s measurement of
`
`background noise with Milbrandt. Namely, the Petition itself specifically argued
`
`only that it allegedly would have been obvious to apply Chang’s actual
`
`“background noise test circuitry” for measuring background noise to Milbrandt.
`
`(See Pet. at 15-17.) But Milbrandt specifically taught away (i.e., criticized and
`
`disparaged) any circuitry that required a technician visit and “truck roll”—which
`
`was the only type of circuitry disclosed in Chang. Milbrandt’s disclosure in this
`
`regard falls squarely within the Federal Circuit’s controlling law for a “teaching
`
`away”—the law does not require Milbrandt to expressly call out Chang by name in
`
`order to teach away from its undesirable technique.
`
`Second, the Board overlooked and did not address in its Institution Decision
`
`several other reasons raised by Patent Owner for why it would not have been
`
`obvious to combine Chang’s background noise measurement technique with
`
`Milbrandt. These reasons, which are explained and supported more fully in this
`
`Response by Patent Owner’s expert, include that:
`
`(a) applying Chang’s only disclosed “circuitry” for measuring background
`
`noise (circuitry that required a technician visit and truck roll) would have
`
`improperly changed the fundamental principle of operation of Milbrandt;
`
`(b) to the extent that Petitioners were somehow arguing that it would have
`
`
`
`2
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`been obvious to just apply Chang’s overall concept of measuring background noise
`
`to Milbrandt (rather than Chang’s actual allegedly “circuitry”), Petitioners failed to
`
`show any reasonable expectation of success (i.e., Petitioners do not explain how a
`
`person of ordinary skill in the art could have measured background noise in
`
`Milbrandt without Chang’s specific truck roll and technician visit); and
`
`(c) Milbrandt already provides the same result and advantages of Chang’s
`
`background noise measurement, making it nonobvious to add Chang’s superfluous
`
`and redundant technique.
`
`Petitioners cannot rely on the Board to fill in the gaps or defects in its
`
`Petition, or to infer or read into the Petition arguments that Petitioners did not
`
`make. See, e.g., In re Magnum Oil Tools Int'l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir.
`
`2016) (Inter partes review is “a system that is predicated on a petition followed by
`
`a trial in which the petitioner bears the burden of proof” and the Board is not “free
`
`to adopt arguments on behalf of petitioners that could have been, but were not,
`
`raised by the petitioner during an IPR. Instead, the Board must base its decision on
`
`arguments that were advanced by a party, and to which the opposing party was
`
`given a chance to respond.”).
`
`Nor can Petitioners fix the deficiencies and failures of proof in the Petition at
`
`a later stage, for example by offering new arguments or new evidence in a Reply.
`
`See Intelligent Bio-Systems, Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369
`
`
`

`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`(Fed. Cir. 2016) (“the expedited nature of IPRs bring with it an obligation for
`
`petitioners to make their case in their petition to institute”); Office Patent Trial
`
`Practice Guide, 77 Fed. Reg. 48,756, 48,767 (Aug. 14, 2012) (a Petitioner may not
`
`“raise[] a new issue or belatedly present[] evidence” that could have been, but was
`
`not, raised in the Petition, particularly “new evidence necessary to make out a
`
`prima facie case” of unpatentability).
`
`As such, Petitioners’ single Ground for alleged obviousness fails. Patent
`
`Owner respectfully requests that the Board issue a Final Written Decision
`
`upholding the patentability of claims 1-6 of the ‘430 patent.
`
`II. THE ’430 PATENT
`
`The ’430 patent is directed to communicating specific diagnostic and test
`
`information concerning a multicarrier communication channel between
`
`multicarrier transceivers within a multicarrier communication network, digital
`
`subscriber line (DSL) network, for example. In the case of a DSL network, the
`
`transceivers correspond to a customer modem (remote transceiver) and a central
`
`office modem (near transceiver). The test and diagnostic information may be
`
`transmitted by the remote transceiver and received by the near transceiver. The
`
`test and diagnostic information may be used to characterize the multicarrier
`
`communication channel between the two transceivers. (See Ex. 1001, ’430 patent
`
`at Abstract.) The ’430 patent recognizes that in prior art systems, analyzing the
`
`
`
`4
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`condition of the communication channel required a technician to visit the remote
`
`transceiver, i.e. a truck roll. (See Ex. 1001, ’430 patent at 1:21-23.) The ’430
`
`patent recognizes that truck rolls are expensive and time consuming. (Id.) The
`
`claims require the communication of specific test and diagnostic parameters by the
`
`remote transceiver to the near transceiver. The information received may be used
`
`to analyze the communication channel without requiring a truck roll to the remote
`
`transceiver. (See Ex. 1001, ’430 patent at 2:44-56.)
`
`In particular, claims 1-6 of the ’430 patent require transmitting and/or
`
`receiving information representing “frequency domain received idle channel
`
`noise.” The frequency domain idle channel noise information corresponds to the
`
`idle channel noise measured by the remote transceiver at different subchannels.
`
`(See Ex. 2001, Chrissan Decl. at ¶ 21.) The frequency domain idle channel noise
`
`information “allows characterization across the subchannels of the multicarrier
`
`communication channel used by the multicarrier transceiver. Because this
`
`information is generated by an already-installed transceiver and may be
`
`communicated to a more convenient location (i.e., a near-end transceiver), again,
`
`the need for a service technician visit may be eliminated.” (Id.) Also, because the
`
`frequency domain idle channel noise information is representative of the idle
`
`channel noise measured by the remote transceiver for subchannels of the
`
`multicarrier communication channel, “the result is that the near-end transceiver, a
`
`
`
`5
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`monitoring system and/or a technician may identify subchannels that are
`
`experiencing excessive background noise, impulse noise or crosstalk.” (Id.)
`
`III. CLAIM CONSTRUCTION
`
`For purposes of this IPR only, Patent Owner does not contest the Board’s
`
`express claim constructions. Any disagreements that Patent Owner might have
`
`with the Board’s constructions are not material to the arguments in this Response,
`
`as the claim constructions are not necessary to resolve any disputes.
`
`In particular, the Board construed the terms “frequency domain received idle
`
`channel noise information,” “array,” and “transceiver.” (See Paper 7, Institution
`
`Decision at pp. 5-8.) The Board found that “frequency domain received idle
`
`channel noise information” is “information about the background noise present in
`
`each of a plurality of frequency subchannels when the subchannels are not in use.”
`
`(Id. at p. 6.) The Board found that an “array” is “an ordered collection of multiple
`
`data items of the same type.” (Id. at 7.) And the Board found that a “transceiver”
`
`is “a device, such as a modem, with a transmitter and receiver.”
`
`IV. PETITIONERS HAVE NOT SHOWN UNPATENTABILITY BASED
`ON THE SINGLE GROUND INSTITUTED
`
`The Petition proposed one ground against the ’430 patent, based on a
`
`combination of four different prior art references. The Board granted review
`
`based this ground, specifically:
`
`
`
`Ground 1. Unpatentability of claims 1-6 under 35 U.S.C. § 103(a) over
`6
`
`
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`U.S. Patent No. 6,636,603 to Milbrandt (“Milbrandt”), in view of U.S. Pat. No.
`
`6,891,803 to Chang et al. (“Chang”), U.S. Pat. No. 6,590,893 to Hwang et al.
`
`(“Hwang”), and American National Standards Institute (ANSI) T1.413-1995
`
`Standard, entitled “Network and Customer Installation Interfaces—Asymmetric
`
`Digital Subscriber Line (ADSL) Metallic Interface” (“ANSI T1.413”).
`
`Patent Owner respectfully submits that Petitioners have not carried its
`
`burden of proving that claims 1-6 are unpatentable. Petitioners have first of all not
`
`met its burden of establishing that the four asserted references can be pieced
`
`together to satisfy all of the elements of the challenged claims—the Board relied
`
`on several demonstrably incorrect factual/technical mischaracterizations by
`
`Petitioners in this regard. Second, even if the references had separately disclosed
`
`all elements of the challenged claims, Petitioners have not met its burden that it
`
`would have been obvious to mix-and-match those elements—Petitioner’ purported
`
`reasons for doing so are conclusory, based on incorrect assumptions, and violate
`
`several basic tenets of controlling Federal Circuit law on obviousness.
`
`Specifically, independent claim 1 of the ’430 patent recites:
`
`1. A transceiver capable of transmitting test information
`over a communication channel using multi carrier modulation
`comprising:
`a transmitter portion capable of transmitting a message,
`wherein the message comprises one or more data variables that represent the
`test information, wherein bits in the message are modulated onto DMT
`symbols using Quadrature Amplitude Modulation (QAM) with more than 1
`
`
`
`7
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`bit per subchannel and wherein at least one data variable of the one or more
`data variables comprises an array representing frequency domain received
`idle channel noise information.
`
`(See Ex. 1001, ’430 patent at claim 1.) Claims 2-6 are also each independent claims, but
`
`vary only with respect to elements not at issue in this proceeding (e.g., whereas claim 1
`
`recites “transmitting” test information claim 2 recites “receiving” test information, etc.).
`
`
`
`For the reasons discussed below, Petitioners have not shown that a combination of
`
`Milbrandt, Chang, Hwang, and ANSI T1.413 would have rendered obvious a transceiver
`
`that transmits a test message comprising an array representing “frequency domain
`
`received idle channel noise information.”
`
`A. The Asserted References Do Not Render Obvious
`Transmitting/Receiving a Test Message Comprising “Idle Channel
`Noise”—Petitioner’ Theory Violates Several Legal Tenets
`
`The claims also each require that the test information transmitted in a
`
`message comprise “idle channel noise information.” In order to satisfy this
`
`limitation, Petitioners allege that it would have been obvious to combine (a)
`
`Milbrandt’s alleged disclosure of transmitting test information with (b) Chang’s
`
`alleged disclosure of measuring “background noise.” (See Pet. at 14-20.)
`
`Patent Owner raised four reasons in its Preliminary Response why adding
`
`Hwang’s method of measuring background noise to Milbrandt would not have
`
`been obvious. These include that:
`
`(1) Milbrandt teaches away from using Chang’s type of “circuitry” for
`
`
`
`8
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`measuring background noise;
`
`(2) Petitioners have not alleged any other way of just combining Chang’s
`
`overall concept of measuring background noise into Milbrandt, and if Petitioners
`
`had they have not shown a reasonable expectation of success in doing so;
`
`(3) Incorporating Chang’s background noise measurement would have
`
`improperly changed Milbrandt’s fundamental principle of operation;
`
`(4) Regardless of the manner in which background noise is measured,
`
`adding that capability to Milbrandt would have been redundant and unnecessary.
`
`In instituting review, the Board only addressed one of these four reasons for
`
`non-obviousness—Patent Owner’s “teaching away” argument. (See Paper 7,
`
`Institution Decision at 20-21.) Patent Owner respectfully submits that the Board
`
`misapprehended Petitioner’ argument and the governing law in this regard. But in
`
`addition, the Board overlooked or misapprehended Patent Owner’s other three
`
`arguments, each of which mandates against a finding of obviousness.
`
`1. Milbrandt Teaches Away From Using Chang’s
`“Circuitry” For Measuring Background Noise
`
`Chang discloses only one way to measure background noise—using two
`
`units attached to opposite ends of a transmission line to be tested, which must be
`
`separately activated and read at each end. Nowhere does Chang suggest how
`
`background noise could be measured without such units attached at opposite ends
`
`
`
`9
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`of the line. And Petitioners do not point to or allege any other way that a person of
`
`ordinary skill in the art would have known how to measure background noise.
`
`In fact, Petitioners specifically argued only that it allegedly would have been
`
`obvious to incorporate Chang’s “background noise test circuitry” for measuring
`
`background noise into Milbrandt using Chang’s alleged “known methods.”1 (See
`
`Pet. at 15-17.) In other words, Petitioners specifically argued only that it would
`
`have been obvious to use Chang’s actual physical equipment in Milbrandt—
`
`
`1 Apparently in response to Patent Owner’s argument in this regard in the Patent
`
`Owner Preliminary Response, Petitioner’s expert (Dr. Kiaei) attempted to broaden
`
`his opinions regarding Chang at his deposition. (See Ex. 2005, Kiaei Dep. Tr. at
`
`23:17-25:7.) He did so not in response to any question, but unilaterally. (See id.)
`
`When pressed, however, Dr. Kiaei could point to nowhere in his declaration where
`
`he ever offered an opinion that Chang’s test method could be used to automatically
`
`transmit background noise information without a truck roll. (See id. at 25:8-
`
`29:14.) Dr. Kiaei pointed to inapplicable statements in his declaration regarding
`
`Chang storing “executables,” but his attempt to read more into those statements in
`
`his declaration is not credible and should be rejected by the Board. (See id.)
`
`
`
`
`
`10
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`equipment that required a technician visit and “truck roll.”2 The Board’s criticism
`
`that “Patent Owner’s arguments are narrowly based on incorporating physically all
`
`technicalities of Chang into Milbrandt” (see Paper 7, Institution Decision at 20) are
`
`therefore misplaced. Patent Owner is addressing Petitioner’ own argument.
`
`Petitioner’ argument in this regard, however, fails in view of Milbrandt’s
`
`own teachings. Specifically, Milbrandt teaches that a “truck roll”—a “dispatch of
`
`a service technician to install communication equipment or to configure the
`
`telephone line at the customer premises . . . to determine the data rate capacity of a
`
`particular telephone line” is highly undesirable because it “is time consuming and
`
`
`2 The Board, in a footnote, indicated that it did not believe that Petitioner was
`
`making such an argument, citing to the declaration of Petitioner’s expert. (See
`
`Paper 7, Institution Decision at fn. 6.) But Petitioner’s statements in the Petition
`
`are unambiguous (see above), and arguments not found in the Petition cannot be
`
`incorporated from the declaration of an expert. See 37 C.F.R. § 42.6(a)(3). And in
`
`any event, Kiaei also makes the same argument—that it allegedly would have been
`
`obvious to incorporate Chang’s actual “background noise test circuitry” according
`
`to “known methods” into Milbrandt. (See Ex. 1009, Kiaei Decl. at ¶ 98.) Kiaei
`
`does not allege that a person of ordinary skill in the art would have known how to
`
`measure background noise any way other than Chang’s method.
`
`
`
`11
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`cost prohibitive for the data services provider and the subscriber.” (Ex. 1011,
`
`Milbrandt at 2:9-15.) One goal of Milbrandt was to substantially eliminate or
`
`reduce such disadvantages. (See id. at 2:19-21.) To that end, Milbrandt discloses
`
`and teaches a method of determining and controlling the power of modems,
`
`including measuring noise, remotely and without any need for a “truck roll.” (See
`
`id. at 6:66-7:7, 10:18-32, Figs. 5-7, 11:38-53.)
`
`Similarly, the ’430 patent itself also explains that the state of the art at the
`
`time disparaged any measurement methods requiring a technician visit or truck
`
`roll. (See Ex. 1001, ’430 patent at 1:21-23 (stating that test or diagnostic methods
`
`requiring a “dispatching a technician to the remote site, e.g., a truck roll” are “time
`
`consuming and expensive”), 2:18-23 (stating that it is desirable to test or diagnose
`
`a communication line “without the technician having the physically visit, i.e., a
`
`truckroll, to the remote site to collect data”).
`
`In contrast, Chang specifically discloses only one “background noise test
`
`circuitry” and one “known method”—a method for measuring background noise in
`
`a transmission line that requires a truck roll. Specifically, Chang discloses portable
`
`“test sets” that can be connected to a “twisted wire pair” to test, among other
`
`things, background noise on the wire pair:
`
`
`
`12
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`
`
`(Ex. 1012, Chang at Fig. 7, 4:1-2 (“FIG. 7 shows a test set up for transmission line
`
`impairment testing.”), 2:59-61 (“line impairment tests can include . . . background
`
`noise . . .”). Specifically, when performing “line impairment tests” such as testing
`
`the background noise on a line between a central office and a remote modem, test
`
`sets must be physically connected and read at both ends of the line, as shown
`
`below:
`
`
`(Ex. 1012, Chang at Fig. 9F3, 15:7-15 (“Fig. 9F shows a test set up for
`
`
`3 Chang does disclose a test setup for “testing ATU-R function” that includes only
`
`a test set at the Central Office end, however, that test setup only “verifies that the
`
`customer premise equipment is working properly” and is not disclosed as being
`
`
`
`
`
`13
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`simultaneous ATU-C and ATU-R emulation. . . . . In the simultaneous ATU-C and
`
`ATU-R emulation mode, test sets 200 verif[y] that the wire pairs can carry ADSL
`
`with an acceptable error rate.)
`
`
`
`For “impairment testing” in Chang, each of the separate tests must be
`
`manually configured and operated at each respective end. (See Ex. 1012, Chang at
`
`11:36-38.) Chang repeatedly refers to the “test sets” as equipment that is used by
`
`“technicians” in a “mobile environment.” (See, e.g., 2:24-32 (“[T]he line
`
`qualification and connectivity testing are often performed in a mobile environment.
`
`The service technicians generally move from site to site to test the local loop. . . .
`
`Conventional test equipment are generally bulky and cumbersome, and not well
`
`suited for a mobile environment.”), 2:36-39 (“During the testing process,
`
`measurements are made and the test results are provided to a service technician
`
`who then configures the xDSL connection accordingly.”).))
`
`Thus, Milbrandt specifically and expressly teaches away from using a
`
`method or circuitry like Chang’s for measuring background noise. (See Ex. 2001,
`
`Chrissan Decl. at ¶¶ 71-80.) Milbrandt’s statements specifically “criticize,
`
`discredit, or other discourage” using a truck roll or technician visit by stating that
`
`
`capable of conducting “impairment tests” such as tests for background noise. (Ex.
`
`1012, Chang at Fig. 9H, 15:20-26.)
`
`
`
`14
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`doing so is time consuming and cost prohibitive. (See Paper 7, Institution Decision
`
`at 21; see also Ex. 2001, Chrissan Decl. at ¶¶ 71-80.)
`
`Importantly, Petitioner’ own expert (Dr. Kiaei) agreed at his deposition that
`
`at the time of the invention of the ‘412 patent, any test method that required a truck
`
`roll was known to be less desirable than a test method that could be done remotely
`
`at a central office. (See Ex. 2005, Kiaei Dep. Tr. at 36:23-37:1 (“Q: So in 1999,
`
`do you agree that a truck roll was considered undesirable for testing a DSL line
`
`parameter? A: In general, yes . . .”).) He also agreed that any statement such as
`
`Milbrandt’s that an approach is “cost prohibitive and time consuming” is a
`
`“criticism of that approach.” (Id. at 40:21-24.)
`
`As such, under the controlling law, this could not be more a more by-the-
`
`letter example of a “teaching away.” For example, in Depuy Spine, Inc. v.
`
`Medtronic Sofamor Danek, a reference was found to teach away from a rigid screw
`
`where it merely disclosed that a “shock-absorber” screw “greatly facilitates the
`
`surgical procedure.” 526 F. Supp. 2d 162, 171-172 (Fed. Cir. 2007). Takeda
`
`Chemical Indus., Ltd. v. Alphapharm Pty., Ltd. similarly involved a prior art
`
`reference that taught away from using phyridyl compounds where it merely
`
`associated them with “negative effects” such as weight gain. See 492 F.3d 1350,
`
`1358-59 (Fed. Cir. 2007). Santarus, Inc. v. Par Pharm., Inc. found no obviousness
`
`in combining a secondary reference teaching the use of non-enteric coated
`
`
`
`15
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`conventional oral dosage forms where the primary reference taught that such
`
`dosage forms “degrade too quickly.” See 694 F.3d 1344, 1355 (Fed. Cir. 2012). In
`
`re Brat found that a prior art reference taught away from uniting two lenses where
`
`doing so would result in “poor performance of image formation.” 16 U.S.P.Q.2d
`
`(BNA) 1812, 1813 (Fed. Cir. Oct. 3, 1990) (unpublished). And in Ex parte Jones,
`
`the Board found that a reference taught away from a display at a single space meter
`
`where it taught that using one would result in undesirable “power consumption.”
`
`Appeal No. 2014-008262 (P.T.A.B. Nov. 29, 2016).
`
`In other words, the law does not require that a reference expressly say, in
`
`those exact words, that a patented approach is highly discouraged or taught away.
`
`Nor does the law require that a reference specifically call out, by name, a
`
`secondary reference as being unsuitable or unworkable. If that was the case,
`
`findings of a teaching away would be much rarer than the law reflects. Rather,
`
`under the law it is enough if the prior art point out disadvantages, negative effects,
`
`or other criticisms with an approach. This is exactly what Milbrandt discloses with
`
`respect to Chang’s truck-roll approach for performing a test or diagnosis.

`
`Petitioners Did Not Establish a Reasonable Expectation of
`Success in Just Using Chang’s Overall “Concept” of
`Measuring Background Noise in Some Other Manner
`
`The Board also overlooked and did not address another argument presented
`
`by Patent Owner—that even if Petitioners had argued that it more generally would
`
`
`
`16
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`have been obvious to just incorporate Chang’s overall concept of measuring
`
`background noise into Milbrandt, without using Chang’s physical equipment, then
`
`Petitioners failed to show any reasonable expectation of success in doing so.
`
`Under the law, however, a party who petitions the Board for a determination
`
`of obviousness “must show that a skilled artisan would have been motivated to
`
`combine the teachings of the prior art references to achieve the claimed invention,
`
`and that the skilled artisan would have had a reasonable expectation of success
`
`from doing so.” 3D-Matrix, Ltd., v. Menicon Co., Ltd., IPR2014-00398, Paper 11,
`
`at 15 (Aug. 1, 2014) (quoting Proctor & Gamble Co. v. Teva Pharms. USA, Inc.,
`
`566 F.3d 989, 994 (Fed. Cir. 2009) (citations omitted; emphasis added); Actelion
`
`Pharma, Ltd. v. Icos Corp., IPR2015-00561, Paper 50 (P.T.A.B. Aug. 3, 2016)
`
`(“Motivation to combine and reasonable expectation of success are two legal issues
`
`not to be conflated.”) (emphasis added); Ex partes Imai, Appeal 2012-003246
`
`(P.T.A.B. Sept. 30, 2014) (“While it is true that the test for obviousness is not
`
`whether the features of a secondary reference may be bodily incorporated into the
`
`structure of the primary reference, this does not mean that finding isolated features
`
`is all that is needed to establish obviousness.”).
`
`It is not enough for a Petitioners or Petitioners’ expert to just conclusorily
`
`allege that a person of ordinary skill would have known how to make such a
`
`modification or combination, or that doing so would have been “predictable”—
`
`
`
`17
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`rather, a Petitioner must provide a persuasive analysis of exactly how such a
`
`combination or modification would have worked in practice. See, e.g., Allsteel,
`
`Inc. v. Dirtt Environmental Sol., IPR2015-01690, Paper 10 (P.T.A.B. Jan. 27,
`
`2016) (expert testimony that allegedly obvious modification would not have “any
`
`significant engineering obstacle” was “not given much weight . . . because it is
`
`conclusory”); Daifuku Co., Ltd. v. Murata Machinery, Ltd., IPR2015-01538, Paper
`
`11 (P.T.A.B. Jan. 19, 2016) (“Petitioner and Dr. Sturges have not provided a
`
`persuasive analysis of . . how the modified loading system would work in
`
`practice.”). See also, ActiveVideo Networks, Inc. v. Verizon Communications, Inc.,
`
`694 F.3d 1312, 1327 (Fed. Cir. 2012) (an expert’s “conclusory statement” that a
`
`person of ordinary skill in the art “would have known” how to combine the
`
`references is “not sufficient and is fraught with hindsight bias”); e.g., T-Mobile
`
`USA, Inc., et al v. Mobile Telecomm. Tech., LLC, IPR2015-00017, Paper 9
`
`(P.T.A.B. April 8, 2015) (“A mere allegation that the combination would have
`
`yielded a predictable result is insufficient to show the possible predictability . . .”).
`
`For example, in Coalition for Affordable Drugs VII LLC v. Pozen, Inc., the Board
`
`rejected a conclusory allegation of predictability, stating that:
`
`“The only evidence that Petitioner cites for its assertion regarding
`‘predictable results’
`in relation
`to NSAIDs
`is Dr. Shargel’s
`Declaration at paragraph 198, which repeats the statements presented
`in the Petition on this point, without citing any evidence itself.
`Conclusory assertions by Petitioner, merely repeated in conclusory
`
`
`
`18
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01006
`
`and unsupported statements by an expert witness in support, are not
`persuasive here.”
`
`Id. at IPR2015-01680, Paper 18 (P.T.A.B. 2016) (internal citations omitted).
`
`Here, as discussed, Petitioners only allege that it would have been obvious to
`
`use Chang’s actual “known technique” or “background noise test circuitry” in
`
`Milbrandt. (See Pet. at 16.) Chang’s only known technique or circuitry requires a
`
`technician visit and truck roll. (See supra at Ex. 2001, Chrissan Decl. at ¶¶71-80.)
`
`To the extent that Petitioners intended to argue that it would have somehow been
`
`obvious to add the ability to measure background noise to Milbrandt without a
`
`technician visit and truckroll, Petitioners fails to address in any way how that could
`
`be accomplished. (See Pet. at 14-17.) Nor do Petitioners provide any evidence (or
`
`even any allegation) that a person of ordinary skill in the art would have known
`
`how to do so. (See id.)
