`
`INTRODUCTION
`
`
`
`Patent Owner Jerry Harvey Audio Holding, LLC (“Patent Owner”),
`
`respectfully submits this response to the Petition for Inter Partes Review of U.S
`
`patent 8,925,674 (“the ‘674 patent”). The Board instituted review of claims 1-11,
`
`13-18 and 20 of the ‘674 patent on seven grounds summarized as anticipation by
`
`Harvey ‘806 and obviousness over either Saggio or Harvey ‘806 alone or in
`
`combination with other references. Paper 8 at 63. For the reasons discussed below,
`
`the Board should find that Petitioner has not carried its burden to prove
`
`unpatentability on any of the instituted grounds.
`
`The ‘674 patent claims canalphones with two drivers of different frequencies
`
`having their signals phase corrected by either: (i) a sound tube for the high driver
`
`that is longer than the sound tube for the low driver, or (ii) a processor. See, e.g.,
`
`Ex. 1001, 2:53-64, 3:15-19. However, as the Board found in its Institution
`
`Decision, merely using a longer tube for a high driver or an arbitrary processor will
`
`not inherently phase correct signals as required by each of the '674 patent's claims.
`
`Paper 8 at 15; Ex. 1001, claim 1 (“to phase correct”), claim 9 (“phase correcting”),
`
`and claim 21 ("to: … phase correct”). To confirm phase correction as claimed by
`
`the ‘674 patent, one can graph the canalphone’s phase response. Ex. 1001, Fig. 7,
`
`4:56-57.
`
`
`
`
`
`1
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`
`Harvey ‘806 taught phase correcting signals from two drivers of different
`
`frequencies by using a longer sound tube for the low driver, the exact opposite of
`
`that claimed by the ‘674 patent, and there is no evidence in the record to confirm
`
`Harvey ‘806’s signals were actually phase corrected as claimed by the ’674 patent.
`
`Thus, Petitioner has not carried its burden to prove Harvey ‘806 anticipated the
`
`challenged claims.
`
`Regarding whether the ‘674 patent’s claims were obvious, while the general
`
`concept of phase correction by either offsetting a high frequency speaker to be
`
`farther away than a low frequency speaker or using a processor were known for
`
`loudspeakers, Petitioner has not shown that one of ordinary skill in the art would
`
`have either been motivated to use those general loudspeaker concepts to phase
`
`correct signals from drivers in canalphones or had a reasonable expectation of
`
`success in doing so. Harvey ‘806 in fact taught using a longer tube for the high
`
`driver was not possible given packaging constraints of canalphones and the
`
`heightened sensitivity of high drivers to separation induced audio degradation, both
`
`of which dictated that it be the low driver that have a longer sound tube, not the
`
`high driver as claimed by the ‘674 patent.
`
`The only evidence offered by Petitioner on the issue of motivation is
`
`unsupported conclusory assertions by its expert, but such naked assertions are
`
`
`
`
`
`2
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`inadequate to establish motivation especially when the prior art teaches the exact
`
`opposite of what is claimed, which is the case here. On the issue of reasonable
`
`expectation of success, Petitioner offers no evidence at all.
`
`Thus, Petitioner has not carried its burden of proving unpatentability on the
`
`instituted obviousness grounds.
`
`II. THE ‘674 PATENT
`
`
`
`The ‘674 patent relates to canalphones with at least two drivers, including a
`
`high audio driver and a low audio driver, wherein the signals of the two drivers are
`
`phase corrected. Ex. 1001, 2:49-57. “[C]analphones are personal listening devices
`
`that are substantially smaller than a person's outer ear,” and “worn in the ear of the
`
`user and not over and/or around the ear of the user.” Id., 1:28-30, 38-39.
`
`“[C]analphones are also referred to as in-ear monitors due to how the canalphone is
`
`worn by a listener.” Id., 1:36-37.
`
`The signals of the two drivers in the ‘674 patent’s canalphone are phase
`
`corrected by either having: (i) a sound tube for the high driver that is longer than
`
`the sound tube for the low driver, or (ii) a processor. Id., 2:62-64, 7:52-57. One
`
`way to achieve phase correction is for the time response of the low audio signal to
`
`pass through the canalphone housing to be used as a control point to set the other
`
`audio signal’s phase. Id., 3:27-31. The ‘674 patent does not teach phase correction
`
`
`
`
`
`3
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`can be achieved with any longer tube for a high driver or with any processor. For
`
`that reason, to confirm a canalphone has been phase corrected, the ‘674 patent
`
`provides an example phase corrected response in Fig. 7, reproduced below.
`
`
`
`Id., Fig. 7, 4:56-57. The top graph shows a phase corrected response (the red line)
`
`compared to an uncorrected response. Id., 8:8-11. The ‘674 patent’s invention
`
`produces a corrected phase response that is much flatter and straighter than the
`
`uncorrected phase response throughout the frequency range.

`U.S. Patent No. 8,925,674
`
`
`III. PETITIONER HAS NOT CARRIED ITS BURDEN TO
`DEMONSTRATE THE UNPATENTABILITY OF ANY
`CHALLENGED CLAIM
`
`Petitioner has not carried its burden to prove any of the challenged claims
`
`are unpatentable. First, Harvey ‘806 did not teach phase correcting signals from
`
`two drivers in a canalphone by making the sound tube for the high driver longer, as
`
`claimed by the ‘674 patent. Harvey ‘806 in fact taught the exact opposite. There is
`
`also no evidence showing Harvey 806’s signals were actually phase corrected.
`
`Second, Petitioner has not shown that one of ordinary skill in the art would have
`
`either been motivated to modify or combine the prior art references to achieve the
`
`‘674 patent’s claimed invention or had an expectation of success in doing so. The
`
`prior art actually taught the claimed invention was not possible. The Board should
`
`thus find that Petitioner has not carried its burden to prove the challenged claims
`
`are unpatentable.
`
`A. Harvey ‘806 Does Not Anticipate Any Claim of the ‘674 Patent
`
`To be anticipatory, a reference must disclose “all of the limitations of the
`
`claims arranged or combined in the same way as recited in the claims.” Vizio, Inc.
`
`v. Int’l Trade Comm’n, 605 F.3d 1330, 1342 (Fed. Cir. 2010). While Harvey ‘806
`
`taught canalphones with two drivers of different frequencies, Harvey ‘806 did not
`
`teach their signals being phase corrected by using either a sound tube for the high
`
`
`
`
`
`5
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`driver longer than the sound tube for the low driver or a processor, as required by
`
`the ‘674 patent’s claims. Petitioner also has failed to provide any evidence that
`
`Harvey ‘806 actually achieved phase correction. Thus, Harvey ‘806 does not
`
`anticipate any claim of the ‘674 patent.
`
`Petitioner makes no argument that Harvey ‘806 taught a processor, and
`
`instead relies on Harvey’s teaching of a sound tube for its high driver that is
`
`shorter than the sound tube for its low driver to suggest that Harvey 806’s signals
`
`are phase corrected as claimed in the ‘674 patent. Pet., 36 (citing Ex. 1005, ¶¶ 32-
`
`45). But Petitioner fails to point to any portion of Harvey ‘806 showing that its
`
`signals are phase corrected by using a sound tube for the high driver that is longer
`
`than the sound tube for the low driver. Instead, Petitioner argues that because
`
`Harvey ‘806 teaches phase correction by making the sound tube for the low driver
`
`longer, it also taught phase correction by making the sound tube for the low driver
`
`shorter. Pet., 37. This interpretation directly contradicts Harvey ‘806 itself.
`
`Harvey ‘806 expressly states it is only phase correcting by making the tube
`
`for the low driver longer. Harvey ‘806 explains that, because “packaging
`
`constraints typically determine the locations of the individual drivers,” “it is
`
`preferable to keep the high frequency driver as close as possible to the eartip, thus
`
`requiring driver offsetting to be performed on the lower frequency driver.” Ex.
`
`
`
`
`
`6
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`1005, 6:17-18, 7:23-26 (emphasis added). Harvey ‘806 further explains, “[t]he
`
`reason for this preference is that the lower frequencies are less susceptible to
`
`separation induced audio degradation (i.e. separation between the driver and the
`
`eartip).” Id., 7:27-30. This is why the only example provided in Harvey ‘806
`
`makes the sound tube for the low frequency driver longer. Pet., 37 (citing Ex.
`
`1005, 6:55-65, Fig. 3).
`
`Thus, Harvey ‘806 did not teach phase correcting signals from two drivers in
`
`a canalphone by making the sound tube for the high driver longer, as claimed by
`
`the ‘674 patent. Harvey ‘806 taught the exact opposite, making the sound tube for
`
`the high driver shorter. The fact that some portions of Harvey ‘806, when
`
`discussing driver offsetting, do not always repeat that it is the low driver being
`
`offset with a longer tube does not mean that Harvey ‘806 taught offsetting either
`
`the low driver or the high driver. The only offsetting taught by Harvey ‘806 is of
`
`the low frequency driver, and Harvey ‘806 explains why that is the case.
`
`Petitioner’s incorrect interpretation, which was adopted by the Board in the
`
`Institution Decision, of Harvey ‘806 as teaching offsetting either the low driver or
`
`the high driver with a longer sound tube expressly contradicts Harvey’806’s
`
`teaching.
`
`Petitioner cites ClearValue, Inc. v. Pearl River Polymers, Inc., 668 F.3d
`
`
`
`
`
`7
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`1340, 1344 (Fed. Cir. 2012), for the argument that a reference does not fail to
`
`anticipate simply because it “teaches away.” Patent Owner agrees, but Harvey ‘806
`
`does not “teach away” from using a longer sound tube for the high frequency
`
`driver, it does not teach it at all. In ClearValue, the prior art taught the claimed
`
`process, but taught away from using it because it “does not work well.” Id. In that
`
`case, the prior art taught that the claimed process worked, just “not well.”
`
`Here, Harvey ‘806 nowhere taught using a sound tube for the high driver
`
`longer than the sound tube for the low driver to phase correct their signals would
`
`work. Harvey ‘806 only taught phase correction by using a sound tube for the high
`
`driver shorter than the sound tube for the low driver. Harvey ‘806 explained why
`
`that was the only configuration possible, namely that packaging constraints of
`
`canalphones and the heightened sensitivity of high drivers to separation induced
`
`audio degradation “required” that it be the low driver offset with a longer sound
`
`tube, not the high driver. Ex. 1005, 7:23-30. Thus, ClearValue is inapposite.
`
`Further, Petitioner also fails to provide any evidence showing Harvey 806’s
`
`signals are phase corrected, such as by providing a phase response graph like that
`
`provided by the ‘674 patent in Figure 7. The Board stated in its Institution Decision
`
`that, “Figure 7 of the ‘674 patent is merely an example of a phase corrected
`
`response,” and “[i]t is not necessary that every phase corrected signal response
`
`
`
`
`
`8
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`reflect that which is shown in Figure 7.” Paper 8 at 51. Patent Owner agrees, but
`
`that does not mean no showing of phase correction is required in order for Harvey
`
`‘806 to anticipate the claims of the ‘674 patent. There must be some evidence that
`
`Harvey ‘806 achieved phase correction as claimed by the ‘674 patent. Petitioner
`
`has provided no such evidence and the Board cited none in its Institution Decision.
`
`The Board instead assumed phase correction necessarily resulted from Harvey
`
`‘806, an assumption that it is Petitioner’s burden to prove with evidence, which it
`
`has not.
`
`B.
`
`The Asserted Prior Art Does Not Render Any Claim Obvious
`
`If the prior art fails to teach each and every limitation of a claim, Petitioner
`
`must show why there would have been a motivation to supply a missing limitation
`
`in the prior art references, Arendi S.A.R.L. v. Apple Inc., 832 F.3d 1355, 1361 (Fed.
`
`Cir. 2016), and why there would have been an expectation of success in doing so,
`
`Broadcom Corp. v. Emulex Corp., 732 F.3d 1325, 1335 (Fed. Cir. 2013).
`
`Even if all of the limitations of a claim are present in the prior art, “a patent
`
`composed of several elements is not proved obvious merely by demonstrating that
`
`each of its elements was, independently, known in the prior art.” KSR Int’l Co. v.
`
`Teleflex Inc., 550 U.S. 398, 418 (2007). “[T]here must be some articulated
`
`reasoning with some rational underpinning to support the legal conclusion of
`
`
`
`
`
`9
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006); see also KSR, 550
`
`U.S. at 418. And, again, this reasoning must include an explanation of why there
`
`would have been a motivation to supply a missing limitation in the prior art
`
`references, Arendi, 832 F.3d at 1361, and why there would have been an
`
`expectation of success in doing so, Broadcom, 732 F.3d at 1335.
`
`Here, Petitioner has not carried its burden to prove any of the challenged
`
`claims were obvious on the instituted grounds because (i) Saggio did not teach or
`
`suggest phase correcting signals in a canalphone, (ii) Harvey ‘806 taught phase
`
`correcting signals in a canalphone as claimed by the ‘674 patent was not possible,
`
`(iii) Petitioner has not shown that one of ordinary skill in the art would have either
`
`been motivated to modify or combine the prior art references to achieve the ‘674
`
`patent’s “phase corrected” invention, and (iv) Petitioner has not shown that one of
`
`ordinary skill in the art would have had an expectation of success in achieving the
`
`‘674 patent’s “phase corrected” invention, especially given Harvey ‘806’s teaching
`
`that phase correcting signals could not be achieved in the way claimed by the ‘674
`
`patent.
`
`i.
`
`Saggio Did Not Teach Phase Corrected Signals
`
`Several of the instituted obviousness grounds are based on Saggio as the
`
`primary reference. While Saggio taught canalphones with two drivers of different
`
`
`
`
`
`10
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`frequencies, Saggio did not teach that the signals are phase corrected. Petitioner
`
`relies on Saggio’s teaching of a high driver sound tube longer than a low driver
`
`sound tube to suggest that Saggio’s signals are phase corrected. Pet., 17-18 (citing
`
`Ex. 1004, ¶¶ 36-37, Fig. 1). But Petitioner fails to point to any portion of Saggio
`
`teaching that its signals are phase corrected. Petitioner also fails to provide any
`
`evidence showing Saggio’s signals are phase corrected like the phase response
`
`graph provided by the ‘674 patent in Fig. 7.
`
`Moreover, Saggio's FIG. 1 is clearly not drawn to scale, as the depicted
`
`high-frequency driver (109) is drawn substantially larger than the low-frequency
`
`driver (107), (a POSA would have known that tweeters are smaller than woofers in
`
`reality) and Saggio never stated that correct phase is achieved by making the high
`
`driver's tube longer.
`
`Petitioner points to one portion of Saggio that states, “the phase relationship
`
`between two drivers may be tuned by varying the length of the sound-tubes,” but
`
`that is not a showing that the signals are in fact phase corrected. Pet., 18 (citing
`
`Ex. 1004, ¶ 46). On the contrary, the relied on citation – Saggio, ¶0046 ("the phase
`
`relationship between the two drivers may be tuned by varying the length of the
`
`sound tubes and the positions of the driver outputs relative to one another") – says
`
`nothing about whether the phase relationship would be improved or degraded by
`
`
`
`
`
`11
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`making the high driver's sound tube longer. Indeed, Petitioner concedes that if
`
`“something more” than a high sound tube longer than a low tube is required,
`
`Saggio does not teach that “something more.” Pet., 15. Here, the “something more”
`
`that is required is phase correction.
`
`Because Saggio fails to teach or suggest phase corrected signals, Petitioner
`
`has failed to carry its burden to prove unpatentability on any of the instituted
`
`obviousness grounds based on Saggio as the primary reference.
`
`ii. Harvey ‘806 Did Not Teach Phase Corrected Signals
`
`As discussed above with respect to the instituted Harvey ‘806 anticipation
`
`ground, Harvey ‘806 did not teach or suggest phase correcting signals in a two
`
`driver canalphone by sizing the sound tube for the high driver longer than the
`
`sound tube for the low driver. Again, Harvey ‘806 expressly taught that, because
`
`“packaging constraints typically determine the locations of the individual drivers,”
`
`“it is preferable to keep the high frequency driver as close as possible to the eartip,
`
`thus requiring driver offsetting to be performed on the lower frequency driver.”
`
`Ex. 1005, 6:17-18, 7:23-26 (emphasis added). Harvey ‘806 further explained,
`
`“[t]he reason for this preference is that the lower frequencies are less susceptible to
`
`separation induced audio degradation (i.e. separation between the driver and the
`
`eartip).” Id., 7:27-30. This is why the only example provided in Harvey ‘806 made
`
`
`
`
`
`12
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`the sound tube for the low frequency driver longer. Pet., 36 (citing Ex. 1005, 6:55-
`
`65, Fig. 3).
`
`Thus, Harvey ‘806 did not teach phase correcting signals from two drivers in
`
`a canalphone by making the sound tube for the high driver longer, as claimed by
`
`the ‘674 patent. Harvey ‘806 taught the exact opposite, making the sound tube for
`
`the high driver shorter. The fact that some portions of Harvey ‘806, when
`
`discussing driver offsetting, do not always repeat that it is the low driver being
`
`offset with a longer tube does not mean that Harvey ‘806 taught or suggested
`
`offsetting either the low driver or the high driver as Petitioner suggests. The only
`
`offsetting taught by Harvey ‘806 is of the low frequency driver, and Harvey ‘806
`
`explains why offsetting of the low driver is required. Petitioner’s incorrect
`
`interpretation of Harvey ‘806 as teaching or suggesting offsetting either the low
`
`driver or the high driver with a longer sound tube expressly contradicts
`
`Harvey ‘806’s teaching.
`
`Because Harvey ‘806 fails to teach or suggest phase corrected signals as
`
`claimed in the ‘674 patent, Petitioner has failed to carry its burden to prove
`
`unpatentability on any of the instituted obviousness grounds based on Harvey ‘806
`
`as the primary reference.
`
`
`
`
`
`13
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`
`iii. Petitioner Has Not Provided Sufficient Evidence to Show a
`POSA Would Have Been Motivated to Phase Correct
`Signals in a Canalphone As Claimed in the ‘674 Patent
`
`While the use of common sense, common wisdom, and common knowledge
`
`is permitted in an obviousness analysis, it “cannot be used as a wholesale substitute
`
`for reasoned analysis and evidentiary support.” Arendi S.A.R.L. v. Apple Inc., 832
`
`F.3d 1355, 1361–63 (Fed. Cir. 2016). Here, the only evidence offered by Petitioner
`
`and relied on the Board in the Institution Decision to provide a motivation to
`
`modify or combine the prior art to achieve the claimed invention is conclusory
`
`“common sense” testimony from Mr. Young.
`
`For example, regarding whether there was a motivation to combine
`
`Dahlquist’s teachings of loudspeaker offsetting with Saggio’s canalphone having a
`
`high driver with a longer sound tube than a low driver, Petitioner merely cites
`
`Mr. Young’s statement that, “[a] POSA would be motivated to use Dahlquist’s
`
`offset in Saggio’s IEM to improve fidelity.” Pet., 48 (citing Ex. 1003, ¶¶ 179-180).
`
`But Petitioner fails to provide any evidence that shows there was a need for
`
`improved fidelity in canalphones at the time of invention. Instead, Petitioner
`
`merely relies on the assumption that improving fidelity in canalphones would be
`
`common sense, without any evidence to support that assumption. Pet., 32-33.
`
`
`
`
`
`The conclusory statements by Mr. Young cited by Petitioner are precisely
`
`
`
`14
`

`U.S. Patent No. 8,925,674
`
`
`the type of evidence that is insufficient to support an allegation that a POSA would
`
`have been motivated to do what was not done in the prior art. Arendi, 832. F.3d at
`
`1362; Broadcom Corp., 732 F.3d at 1335. Thus, Petitioner has failed to provide the
`
`reasoned analysis and evidentiary support required to show that there was a
`
`motivation to modify or combine the prior art to achieve the ‘674 patent’s claimed
`
`invention.
`
`Further still, when discussing the issue of motivation, Petitioner fails to even
`
`address the teaching in Harvey ‘806 that physical and performance factors
`
`“requir[ed] driver offsetting to be performed on the lower frequency driver.” Ex.
`
`1005, 7:23-26. Nowhere does Petitioner address why one of ordinary skill in the art
`
`would have been motivated to elongate the high frequency driver's sound tube in a
`
`canalphone given Harvey 806’s teachings that extending the sound tube of the low
`
`driver was “required.” This failure to address Harvey ‘806’s contrary teaching
`
`renders all of Petitioner’s obviousness arguments against the ‘960 patent’s “phase
`
`corrected” claims untenable.
`
`In its Institution Decision, the Board cites merely one passage in Saggio to
`
`support its finding that a person of ordinary skill in the art would have been
`
`motivated to phase correct signals from two drivers by extending the length of the
`
`high driver tube. However, that single passage in Saggio merely says that the phase
`
`
`
`
`
`15
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`relationship between two drivers may be “tuned” by varying the length of the
`
`sound tubes. Paper 8 at 25. Saggio does not teach that the phase relationship may
`
`be “corrected” as claimed in the ‘674 patent, which includes the express
`
`requirement that, “the high audio signal’s arrival to the outside of the canalphone
`
`housing [] is closer in time to the low audio signal.” Paper 8 at 13 (citing Ex. 1001,
`
`3:1-5). There is no evidence that Saggio’s “tuning” achieved a “closer in time”
`
`result as required by the ‘674 patent, or that such a result was motivated by Saggio
`
`or any other reference’s teaching.
`
`iv.
`
`Petitioner Has Not Provided Any Evidence to Show a POSA
`Would Have Had a Reasonable Expectation of Success in
`Phase Correcting Signals in a Canalphone As Claimed in
`the ‘674 Patent
`
`On the issue of expectation of success, Petitioner does not provide any
`
`evidence at all. Nowhere in the Petition does Petitioner discuss why one of
`
`ordinary skill in the art, even if motivated to selectively modify or combine the
`
`teachings of the prior art to mirror the claimed invention, would have had a
`
`reasonable expectation of success in doing so. This fact alone makes Petitioner’s
`
`obviousness arguments insufficient, Broadcom Corp., 732 F.3d at 1335, but a
`
`review of the prior art shows why there would in fact not have been an expectation
`
`of success to use either a longer sound tube for a high frequency driver or a
`
`processor to phase correct two signals in a canalphone.
`
`
`
`
`
`16
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`
`First, Harvey ‘806 expressly taught that to achieve phase correction in
`
`canalphones it was “required” that the low driver be offset with a longer sound
`
`tube. Thus, in light of Harvey ‘806, there was no expectation of success in phase
`
`correcting signals by making the sound tube for the high driver longer than the
`
`sound tube for the low driver.
`
`Second, Prakash taught that its processor was typically used in a car stereo, a
`
`much larger audio device than the very small size of canalphones. Petitioner
`
`provides no reason why a POSA would have expected to be able to fit a large
`
`processor appropriate for car stereos into a very small canalphone, and no
`
`reference provided by Petitioner does or suggests such. Ex. 1006, 11:28-29.
`
`Thus, not only has Petitioner failed to even attempt to show why there would
`
`have been an expectation of success, the prior art actually shows there would not
`
`have been. As a result, Petitioner has not carried its burden to prove unpatentability
`
`on the obviousness grounds.
`
`In the Institution Decision, the Board made factual assertions regarding what
`
`one of ordinary skill in the art would have recognized without any basis in the
`
`record. Paper 8 at 29. For example, the Board makes the factual assertions that, “It
`
`is not disputed that delaying the arrival of a signal that has a phase lead will
`
`synchronize the leading signal with the lagging signal. There is nothing
`
`
`
`
`
`17
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`unpredictable about that scenario.” But no such evidence appears in the record, and
`
`it is indeed contradicted by the Board’s finding that merely having one sound tube
`
`longer than the other will not necessarily result in phase correction. Paper 8 at 15.
`
`Further, Petitioner also fails to provide any evidence showing any of the
`
`prior art signals are phase corrected as claimed by the ‘674 patent, such as by
`
`providing a phase response graph like that provided by the ‘674 patent in Figure 7.
`
`The Board stated in its Institution Decision that, “Figure 7 of the ‘674 patent is
`
`merely an example of a phase corrected response,” and “[i]t is not necessary that
`
`every phase corrected signal response reflect that which is shown in Figure 7.”
`
`Paper 8 at 51. Patent Owner agrees, but that does not mean no showing of phase
`
`correction is required in order for the prior art to render the claims of the ‘674
`
`patent obvious. There must be some evidence that the prior art, alone or in
`
`combination, would have led a person of skill in the art to achieve phase correction
`
`as claimed by the ‘674 patent. Petitioner has provided no such evidence and the
`
`Board cited none in its Institution Decision. The Board instead assumed phase
`
`correction necessarily resulted from the prior art, an assumption that it is
`
`Petitioner’s burden to prove with evidence, which it has not.
`
`In short, there is no evidence in the record that a person of skill in the art
`
`would have expected to be able to phase correct two signals from two drivers of
`
`
`
`
`
`18
`
`
`
`Case IPR2017-01091
`U.S. Patent No. 8,925,674
`
`
`different frequencies in a canalphone by extending the length of the high audio
`
`sound tube. Petitioner’s only evidence on the point is pure conjecture and, in fact,
`
`contradicted by the prior art.
`
`IV. THESE PROCEEDINGS ARE UNCONSTITUTIONAL
`
`Once a patent is granted, it “is not subject to be revoked or canceled by the
`
`president, or any other officer of the Government” because “[i]t has become the
`
`property of the patentee, and as such is entitled to the same legal protection as
`
`other property.” McCormick Harvesting Mach. Co. v. C. Aultman & Co., 169 U.S.
`
`606, 608-09 (1898).
`
`The Supreme Court recently heard argument in Oil States Energy Servs., v.
`
`Greene's Energy Grp., No. 16-712, to decide whether inter partes review, an
`
`adversarial process used by the Patent and Trademark Office (PTO) to analyze the
`
`validity of existing patents, violates the Constitution by extinguishing private
`
`property rights through a non-Article III forum without a jury. Patent Owner
`
`disputes the constitutionality of these proceedings pending the outcome of the
`
`Supreme Court’s decision in Oil States.

`
`
`V. CONCLUSION
`
`
`
`For the reasons discussed above, Petitioner has not demonstrated the
`
`unpatentability of any challenged claim. Accordingly, Patent Owner requests that
`
`the Board issue a final written decision finding patentable all claims challenged.
