`
`I. INTRODUCTION
`Intellectual Ventures II LLC (“Patent Owner”) filed a Request for
`Rehearing (Paper 37, “Req. Reh’g”) of our Final Written Decision (Paper
`36, “Final Dec.”) determining claims 1, 5, 9, 10, 12, 24, 28, 32, 33, and 34 of
`U.S. Patent No. 6,516,442 B1 (Ex. 1001, “the ’442 patent”) to be
`unpatentable. Patent Owner’s Request for Rehearing is solely focused on
`the issues relating to full-duplex channels. Patent Owner points to two
`alleged defects in our Final Written Decision—namely, we misapprehended
`or overlooked (1) the alleged lack of evidence in the Petition that Reschke
`discloses a full-duplex channel (Req. Reh’g 11–12) and (2) Patent Owner’s
`argument in Patent Owner’s Sur-Reply (Paper 33, “PO Sur-Reply”)
`regarding the purported lack of inherent disclosure of full-duplex channels in
`Reschke (Req. Reh’g 12–14). In addition, Patent Owner repeats its assertion
`made in its Sur-Reply that it was deprived of due process because Patent
`Owner was not permitted to submit declaration evidence on “the lack of
`inherent disclosure [in Reschke] of full-duplex communications” after the
`oral hearing. Id. at 14–15; see PO Sur-Reply 6.
`In view of these alleged oversights, Patent Owner requests that we
`(1) vacate the Final Written Decision and find that the challenged claims
`have not been shown to be unpatentable or, in the alternative, (2) “reopen the
`record” to allow Patent Owner to submit a declaration regarding the
`purported lack of inherent disclosure of a full-duplex channel in Reschke.
`Req. Reh’g 2, 15. For the reasons set forth below, Patent Owner’s Request
`for Rehearing is denied.

`
`II. STANDARD OF REVIEW
`A party requesting rehearing bears the burden of showing that the
`decision should be modified. 37 C.F.R. § 42.71(d). The challenging party
`“must specifically identify all matters the party believes the Board
`misapprehended or overlooked, and the place where each matter was
`previously addressed” in a paper of record. Id. With this in mind, we
`address the arguments presented by Patent Owner.
`
`
`III. ANALYSIS
`A. Alleged Lack of Evidence on Full-Duplex Communication in the Petition
`Patent Owner asserts that the Petition contained no argument or
`evidence that Reschke discloses full-duplex communication. Req. Reh’g 11.
`Patent Owner further argues that our Institution Decision (Paper 9, “Inst.
`Dec.”) and Final Written Decision overlooked this lack of evidence in the
`Petition and erroneously determined that Petitioner met its burden at each
`stage. Req. Reh’g 12.
`Patent Owner mischaracterizes our decisions as well as the record
`evidence underlying the decisions. As discussed in our Institution Decision
`and Final Written Decision, the Petition identified separate circuitries for
`forward and reverse communication pathways in Reschke’s channels and
`argued, based on this disclosure, that Reschke teaches bi-directional and
`full-duplex channels. See Pet. 38–41 (identifying separate circuitries for a
`“forward” pathway (in Fig. 4A) and “reverse” pathway (in Fig. 4B) of a
`channel in Reschke) (citing Ex. 1003, col. 11, ll. 37–40, col. 14, ll. 8–11,
`
`3
`
`
`
`IPR2016-01106
`Patent 6,516,442 B1
`
`
`Figs. 4A, 4B; Ex. 1002 ¶¶ 136–140); Inst. Dec. 28–30 (citing Pet. 38–41);
`Final Dec. 45 (citing Pet. 39–41), 47–48.
`In our Institution Decision, noting that Patent Owner’s Preliminary
`Response did not address Petitioner’s argument and evidence regarding the
`“forward” and “reverse” pathways depicted in Reschke’s Figures 4A and 4B
`(Inst. Dec. 29–30), we invited the parties to address the “channels”
`limitation further in their papers, including whether the “forward” and
`“reverse” pathways in the data switching circuitry of Reschke identified by
`Petitioner “can operate at the same time to provide full-duplex transmission”
`(id. at 30). In its Patent Owner Response (Paper 15, “PO Resp.”), Patent
`Owner rejected our invitation as “improper burden shifting” and did not
`discuss the “forward” and “reverse” pathways of the data switching
`circuitries described in Figures 4A and 4B of Reschke and relied upon by
`Petitioner in the Petition. PO Resp. 50–51.
`As discussed in our Final Written Decision, our invitation to both
`parties to discuss the implications of the data switching circuitry disclosed in
`Figures 4A and 4B of Reschke in no way shifts the burden of proof, which
`remained at all times on Petitioner. Final Dec. 64. More to the point for
`purposes of this Decision, the record shows that Patent Owner was aware of
`our discussion of the evidence in the Petition regarding Reschke’s teaching
`of full-duplex channels and in fact responded to our discussion, if only to
`reject our invitation to discuss the evidence presented in the Petition.
`Nonetheless, Patent Owner in its Request for Rehearing disregards the
`extensive discussion in our decisions (see Req. Reh’g 11 (citing Inst. Dec.
`28–30, Final Dec. 43–44)) and contends we overlooked the purported lack of
`
`4
`
`
`
`IPR2016-01106
`Patent 6,516,442 B1
`
`
`evidence in the Petition. Patent Owner’s argument is unpersuasive because
`it is based on a mischaracterization of our decisions and the underlying
`evidence of record.
`Patent Owner further asserts that our Final Written Decision
`overlooked the testimony of Patent Owner’s declarant, Donald Alpert,
`Ph.D., that “Reschke lacks simple disclosure of a processor that can read
`data from memory simultaneously with writing data to memory, which
`might evince simultaneous communications in both directions.” Req. Reh’g
`14 (citing id. § II.I); see also id. at 10 (citing Ex. 2020 ¶ 81), 7 (citing PO
`Resp. 51–53; Ex. 2020 ¶ 81).
`Patent Owner again mischaracterizes our Final Written Decision and
`the evidence of record. In the cited portion of the Patent Owner Response,
`Patent Owner asserted that “[Reschke’s] Figure 2, like Figure 4, shows data
`proceeding across a data bus in one direction at a time.” PO Resp. 53 (first
`emphasis added) (citing Ex. 2020 ¶ 81). However, as discussed above,
`Patent Owner at the same time did not discuss, due to purported “improper
`burden shifting,” Figures 4A and 4B of Reschke and whether the “forward”
`and “reverse” pathways of the data switching circuitries depicted in Figures
`4A and 4B can operate simultaneously to provide full-duplex
`communication. Id. at 51. On the very same page of the Patent Owner
`Response, Patent Owner lumped Figures 4A, 4B, and 4C of Reschke
`together as “Figure 4” and asserted without adequate explanation that
`“Figure 4 only shows communications crossing the buses in one direction at
`a time, not simultaneously.” Id. (citing Ex. 2020 ¶ 81).
`
`5
`
`
`
`IPR2016-01106
`Patent 6,516,442 B1
`
`
`
`In the cited paragraph of Dr. Alpert’s Declaration, Dr. Alpert similarly
`lumped Figures 4A, 4B, and 4C of Reschke together as “Figure 4” and
`opined that “Reschke’s Figure 4 . . . does not show any bus communicating
`information in both directions at the same time” because “there is no
`indication [in Figure 4] that a PU can read data from memory simultaneously
`with writing data to memory.” Ex. 2020 ¶ 81 (emphases added). Petitioner,
`however, identified precisely those indications in Figures 4A and 4B that Dr.
`Alpert did not find in “Figure 4”—that is, the separate circuitries in Figures
`4A and 4B comprising the “forward” and “reverse” communication
`pathways that may be used to transmit data in full-duplex mode “from the
`processors (purple) and memories (yellow) to respective switch interfaces”
`(Pet. 39–40 (underlined emphases added) (discussing the “forward” portions
`of Reschke’s channels described in Figure 4A)) and “from switch interfaces
`to the processors . . . and shared memory” (id. at 40–41 (underlined
`emphases added) (discussing the “reverse” portions described in Figure
`4B)). Dr. Alpert simply disregarded this evidence presented in the Petition,
`as well as our invitation to discuss the significance of Petitioner’s evidence,
`and stated in a conclusory fashion and without adequate explanation that
`“there is no indication that a PU can read data from memory simultaneously
`with writing data to memory.” Ex. 2020 ¶ 81.
`Hence, the record shows that Patent Owner and Dr. Alpert made only
`conclusory statements regarding “Figure 4” and did not address the
`circuitries described in the very same evidence, i.e., Figures 4A and 4B of
`Reschke. We did not misapprehend or overlook Patent Owner’s argument
`or Dr. Alpert’s testimony regarding “Figure 4”; we simply found them
`
`6
`
`
`
`IPR2016-01106
`Patent 6,516,442 B1
`
`
`unpersuasive, given Petitioner’s arguments and evidence that Patent Owner
`and Dr. Alpert did not address.
`
`B. Alleged Lack of Inherent Disclosure of Full-Duplex Channels in Reschke
`Patent Owner contends that our Final Written Decision
`misapprehended the law on inherent disclosure and overlooked Patent
`Owner’s argument that Reschke does not inherently discloses full-duplex
`channels. Req. Reh’g 12–14. Patent Owner’s argument is not persuasive
`because Petitioner did not argue inherent disclosure of full-duplex channels
`in Reschke. Instead, Petitioner argued, and we agreed, that Reschke
`discloses a full-duplex channel to a person of ordinary skill in the art. See,
`e.g., Pet. 41 (“Reschke discloses . . . bi-directional, full-duplex, point-to-
`point channels that transfer packets.”); Paper 18 (“Pet. Reply”), 26 (“[A]
`person of ordinary skill would not believe Reschke to be a half-duplex
`system.” (emphasis added)); Paper 34 (“Pet. Sur-Sur-Reply”), 2
`(“Petitioner’s position is that a person of ordinary skill in the art, reading
`Reschke, would understand that the disclosed channels are capable of full-
`duplex communication and thus are full-duplex.” (emphasis added) (citing
`In re Preda, 401 F.2d 825, 826 (CCPA 1968)), 3 (“Reschke discloses to a
`[person of ordinary skill in the art] that its channels are full-duplex, not half-
`duplex.”); Final Dec. 45 (“We . . . are persuaded that a person of ordinary
`skill in the art would have understood that in Reschke’s system, data can be
`transmitted separately on these separate pathways at the same time.”
`(emphasis added)).
`As discussed above, Petitioner in the Petition identified separate
`circuitries for forward and reverse communication pathways in Reschke’s
`
`7
`
`
`
`IPR2016-01106
`Patent 6,516,442 B1
`
`
`channels and argued that Reschke discloses bi-directional and full-duplex
`channels. See Pet. 38–41. In its Reply, Petitioner responded to Patent
`Owner’s arguments in Patent Owner Response, as well as our invitation to
`discuss whether the “forward” and “reverse” pathways of Reschke can
`operate at the same time to provide full-duplex transmission, and argued that
`Reschke’s channels are capable of full-duplex transmissions because nothing
`in Reschke prevents communications occurring simultaneously on both
`pathways. Pet. Reply 21.
`More importantly, citing the testimony of its declarant, Douglas W.
`Clark, Ph.D., and the supporting evidence discussed in Dr. Clark’s
`Declaration, Petitioner further argued that, in architectures like Reschke’s
`with separate input and output ports (or separate “forward” and “reverse”
`pathways), a control mechanism is necessary for half-duplex operation to
`ensure and enforce that a channel is never used to transmit data on both
`directions at the same time, and that the lack of any such control or
`enforcement mechanism in Reschke shows that a person of ordinary skill in
`the art would not understand Reschke to disclose a half-duplex system, but,
`rather, would understand that Reschke’s channels are full-duplex channels.
`Id. at 26 (citing Ex. 1028 ¶¶ 63–66; Ex. 2003; Ex. 1036, 9). Dr. Clark
`further opined, citing supporting evidence in the record, that one of ordinary
`skill would not have contemplated incurring additional cost to add the extra
`control mechanism necessary for half-duplex transmission, just to reduce the
`performance in Reschke’s system, i.e., limit the transmission of data to one
`direction at a time. Ex. 1028 ¶¶ 62–66. Petitioner also highlighted these
`points during the oral hearing. See Paper 35 (“Tr.”), 9:14–26; 46:11–25.
`

`
`
`
`IPR2016-01106
`Patent 6,516,442 B1
`
`
`
`Although Patent Owner was provided an opportunity to respond to
`Petitioner’s argument and evidence after the oral hearing, Patent Owner’s
`Sur-Reply did not address Petitioner’s argument and evidence that a person
`of ordinary skill in the art would understand Reschke to disclose full-duplex
`channels because Reschke’s data switches do not include additional controls
`that would be necessary for Reschke to perform half-duplex operation. See
`Final Dec. 47 (noting that Patent Owner did not address Petitioner’s
`argument regarding the lack of additional controls in Reschke for enabling
`half-duplex communications). Instead, Patent Owner asserted Petitioner’s
`argument must be an argument for inherent disclosure and argued that
`Petitioner failed to prove inherent disclosure of full-duplex channels in
`Reschke. PO Sur-Reply 3–4.
`In its Sur-Sur-Reply, Petitioner emphasized that it does not rely on
`inherency1 and reiterated that “Petitioner’s position is that a person of
`ordinary skill in the art, reading Reschke, would understand that the
`disclosed channels are capable of full-duplex communication and thus are
`full-duplex.” Pet. Sur-Sur-Reply 2 (citing Preda, 401 F.2d at 826).
`Although Reschke does not use the word “full-duplex” to describe its
`channels, it is well-settled that “the [prior art] reference need not satisfy an
`ipsissimis verbis test,” i.e., identity of terminology is not required, to
`
`
`1 Patent Owner in its Sur-Reply also asserted that Petitioner failed to prove
`yet another argument Petitioner did not make—namely, “Petering-type”
`anticipation. PO Sur-Reply 4–5 (citing In re Petering, 301 F.2d 676 (CCPA
`1962)). Petitioner in its Sur-Sur-Reply similarly noted that Petitioner never
`relied on “Petering-type” anticipation. Pet. Sur-Sur-Reply 2. For the
`reasons discussed below, and because Petitioner never made these
`arguments, they have no bearing on the outcome of this case.

`Patent 6,516,442 B1
`
`
`disclose a claim limitation. In re Gleave, 560 F.3d 1331, 1334 (Fed. Cir.
`2009). Moreover, the prior art reference is read from the perspective of one
`with ordinary skill in the art. See Star Scientific, Inc. v. R.J. Reynolds
`Tobacco Co., 655 F.3d 1364, 1374 (Fed. Cir. 2011) (“Whether prior art
`invalidates a patent claim as obvious is determined from the perspective of
`one of ordinary skill in the art.”); Wasica Fin. GmbH v. Cont’l Auto. Sys.,
`Inc., 853 F.3d 1272, 1284 (Fed. Cir. 2017) (“Anticipation is an inquiry
`viewed from the perspective of one skilled in the art.”) (citing Dayco Prods.,
`Inc. v. Total Containment, Inc., 329 F.3d 1358, 1368 (Fed. Cir. 2003)
`(“[T]he dispositive question regarding anticipation is whether one skilled in
`the art would reasonably understand or infer from the prior art reference’s
`teaching that every claim element was disclosed in that single reference.”));
`Scripps Clinic & Research Foundation v. Genentech, Inc., 927 F.2d 1565,
`1576 (Fed. Cir. 1991) (“[Anticipation requires that there be] no difference
`between the claimed invention and the reference disclosure, as viewed by a
`person of ordinary skill in the art in the field of the invention.”), overruled in
`part on other grounds by Abbott Labs. v. Sandoz, Inc., 566 F.3d 1282, 1293
`(Fed. Cir. 2009). As discussed above, Petitioner’s position has been
`consistently that Reschke discloses a full-duplex channel to a person of
`ordinary skill in the art. See Pet. 41; Pet. Reply 21, 26; Pet. Sur-Sur-Reply
`2–3. Hence, Patent Owner’s assertion that, because Reschke does not
`expressly describe the buses as “full-duplex,” Petitioner’s argument must be
`an argument for inherent disclosure (PO Sur-Reply 3–4; Req. Reh’g 12–13)
`misunderstands or mischaracterizes Petitioner’s argument and evidence.
`
`10
`
`
`
`IPR2016-01106
`Patent 6,516,442 B1
`
`
`
`Similarly, Patent Owner’s assertion in its Request for Rehearing that
`our Final Written Decision misapprehended the law on inherent disclosure
`and overlooked the purported lack of inherent disclosure of full-duplex
`channels in Reschke misunderstands or mischaracterizes the Final Written
`Decision. As discussed above, we determined that, based on the complete
`record, Petitioner had shown sufficiently that Reschke discloses to a person
`of ordinary skill in the art that Reschke’s channels are capable of full-duplex
`communication. Final Dec. 43–48. Having determined that Reschke
`discloses full-duplex channels, it was not necessary for us to also determine
`whether Reschke inherently discloses full-duplex channels to reach a
`decision in this proceeding. Hence, we did not overlook Patent Owner’s
`argument on inherent disclosure (or lack thereof) Patent Owner made in its
`Sur-Reply, but, rather, declined to address the inherency issue that has no
`bearing on the outcome of this case. Also, we could not have
`misapprehended the law on inherent disclosure because our Final Written
`Decision did not include any consideration of any legal issue relating to
`inherent disclosure.
`
`C. Due Process
`Patent Owner asserts that it was deprived of due process because,
`although Patent Owner was allowed to file a Sur-Reply after the oral
`hearing, Patent Owner was not permitted to submit declaration evidence on
`“the lack of inherent disclosure [in Reschke] of full-duplex
`communications” with its Sur-Reply. Id. at 14–15. Patent Owner’s
`arguments in its Request for Rehearing essentially repeat the same due
`
`11
`
`
`
`IPR2016-01106
`Patent 6,516,442 B1
`
`
`process arguments Patent Owner made in its Sur-Reply. See PO Sur-Reply
`6.
`
`In our Final Written Decision, we addressed Patent Owner’s due
`process arguments and determined that Patent Owner had sufficient notice
`and opportunity to be heard. Final Dec. 63–65. Patent Owner’s Request for
`Rehearing does not identify specifically what Patent Owner believes we
`misapprehended or overlooked in the Final Written Decision. Hence, Patent
`Owner’s Request for Rehearing appears to simply disagree with our Final
`Written Decision. Mere disagreement with a decision is not a proper basis
`for rehearing when a party’s arguments were considered and addressed in
`the decision.
`More importantly, the declaration evidence Patent Owner wishes to
`submit relates to the purported “lack of inherent anticipation by Reschke”
`(Req. Reh’g 2) or “the lack of inherent disclosure [in Reschke] of full-
`duplex communications” (id. at 15). Any additional evidence on the
`purported lack of inherent disclosure in Reschke of full-duplex
`communications would not have affected our Final Written Decision
`because the issue of inherent disclosure has no bearing on the outcome of
`this case, for the reasons explained above.
`For the reasons discussed in our Final Written Decision, Patent Owner
`had sufficient notice and opportunity to be heard and, therefore, was not
`deprived of its due process rights in this proceeding. See Final Dec. 63–65.

`Patent 6,516,442 B1
`
`
`
`IV. CONCLUSION
`For the foregoing reasons, we decline to modify our Final Written
`Decision. We also decline to reopen the record to allow Patent Owner to
`submit a declaration regarding the purported lack of inherent disclosure of a
`full-duplex channel in Reschke.
`
`
`V. ORDER
`Accordingly, it is ORDERED that Patent Owner’s Request for
`Rehearing is denied.
