`Patent 9,037,502
`
`INTRODUCTION
`The Petition established that claims 1-3 and 7 are obvious over Rolf in view
`
`of Gatherer, Fritsch, and Frodigh; that claim 5 is obvious over Rolf in view of
`
`Gatherer, Fritsch and Frodigh, in further view of Yukie; that claims 1-3 and 7 are
`
`obvious over Rolf in view of Gatherer and Fritsch, in further view of O’Hara and
`
`Tagg; and that claim 5 is obvious over Rolf in view of Gatherer, Fritsch, O’Hara,
`
`and Tagg, in further view of Yukie. The Petition was supported by extensive
`
`evidence, including dozens of contemporaneous documents and a comprehensive
`
`expert declaration from Dr. Lavian. The Patent Owner did not depose or cross-
`
`examine Dr. Lavian, nor did the Patent Owner submit any expert declaration of its
`
`own. The evidence set forth in the Petition is thus uncontested.
`
`The Patent Owner’s Response instead recycles the same failed arguments the
`
`Board and/or the Federal Circuit have rejected. With respect to the OFDM
`
`limitations, for example, the Patent Owner asserts that a person of ordinary skill in
`
`the art would not have been motivated to utilize OFDM with the cell phone of Rolf.
`
`But the Board rejected this same argument in its Final Written Decision in
`
`MindGeek, S.A.R.L. et al. v. Skky, Inc., IPR2014-01236, which was affirmed by the
`
`Federal Circuit in Skky, Inc. v. MindGeek, S.A.R.L., 859 F.3d 1014 (Fed. Cir. 2017).
`
`As the Board recently observed in a related proceeding, “in MindGeek, the Board
`
`and the Federal Circuit similarly concluded that it would have been obvious to utilize
`
`1
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`OFDM for Rolf’s system of delivering music files to a cellular telephone.”
`
`Case IPR2017-00550
`Patent 9,037,502
`
`
`
`
`(IPR2017-00550, Paper 11, at 10.)
`
`The Patent Owner also recycles arguments—almost verbatim—from its
`
`Preliminary Response, adding little to no analysis responsive to the Board’s stated
`
`rationales for rejecting those arguments in the Institution Decision.1 For example,
`
`the Patent Owner repeats apparent claim construction arguments from its
`
`Preliminary Response with respect to the phrase “processing,” which the Board
`
`correctly rejected in its Institution Decision. The Patent Owner also raises the same
`
`conclusory assertions attacking each reference individually, ignoring the well-
`
`supported reasons for combining the references’ teachings that the Petition presented
`
`and the Institution Decision appreciated. The Patent Owner does not acknowledge,
`
`let alone address, the Board’s treatment of its arguments in its Institution Decision.
`
`The Patent Owner has thus offered nothing of substance to justify a departure from
`
`the Institution Decision.
`
`With respect to the “digital signal processor” (DSP) limitation, the Patent
`
`Owner repeats the assertion that Rolf and Gatherer cannot be combined because Rolf
`
`
`1 For the Board’s reference, a redline showing the near-complete overlap of the
`
`substantive arguments from the Preliminary Response to the Response is submitted
`
`herewith as Exhibit 1073.

`
`is directed to a 3G wireless communication system and Gatherer to a GSM/2G
`
`Case IPR2017-00550
`Patent 9,037,502
`
`
`
`
`system. Similarly for the “OFDM” limitation, the Patent Owner again asserts that
`
`Rolf cannot be combined with either Frodigh or O’Hara and Tagg, based on
`
`unauthenticated documents stating
`
`that
`
`the European Telecommunications
`
`Standards Institute’s (ETSI’s) Special Mobile Group (SMG) decided to use CDMA
`
`as the basis for the 3G standard. But as the Board correctly and repeatedly found,
`
`these arguments are based on gross mischaracterizations of the references and a
`
`misunderstanding of the significance of the SMG’s decision. Patent Owner adds no
`
`new evidence or argument to the record on these points.
`
`For the reasons set forth below and in the Petition, the Petitioners respectfully
`
`requests that the Board find claims 1-3, 5, and 7 unpatentable based on all instituted
`
`grounds.
`
`II.
`
`PATENT OWNER’S CONSTITUTIONAL ARGUMENTS ARE WITHOUT MERIT
`The Patent Owner devotes the first seven pages of its Response to asserting
`
`that inter partes review (IPR) is unconstitutional. The Federal Circuit thoroughly
`
`considered and rejected those arguments in MCM Portfolio LLC v. Hewlett-Packard
`
`Co., 812 F.3d 1284 (Fed. Cir. 2015), cert. denied, 137 S. Ct. 292 (2016). The
`
`Petitioners are obviously aware that the Supreme Court in Oil States has taken up
`
`the issue of the constitutionality of the IPR procedure. But until a decision in Oil
`
`States issues, MCM Portfolio remains controlling law and the IPR procedure is
`
`3
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`constitutional.
`
`
`
`
`Case IPR2017-00550
`Patent 9,037,502
`
`III. CLAIMS 1-3, 5, AND 7 OF THE ’502 PATENT ARE UNPATENTABLE
`A.
`“Digital Signal Processor”
`Claim 1 recites a “wherein the cellphone comprises a receiver and one or more
`
`processors including a digital signal processor.” The Petition explained that “[i]t
`
`would have been obvious to a person of ordinary skill in the art to combine Rolf with
`
`Gatherer, predictably resulting in the cell phone 12 of Rolf having a digital signal
`
`processor.” (Petition, at 27.) In an attempt to find fault with this straightforward
`
`combination, the Patent Owner mischaracterizes Rolf as being directed to 3G
`
`wireless, and Gatherer as being directed to GSM/2G wireless. From these false
`
`premises, the Patent Owner argues that a person of ordinary skill “would not be
`
`motivated to apply GSM or 2G principles to 3G knowing that the technologies could
`
`evolve in very different ways.” (Response, at 30.) This argument should be rejected.
`
`The Board correctly recognized that there is “no basis to suggest that the
`
`skilled artisan would understand that Rolf’s system could only be implemented on a
`
`3G/CDMA cellular network.” (Institution Decision, at 9 (emphasis in original).)
`
`Indeed, Rolf makes clear that data can be transmitted over a “packet switched
`
`network,” which need not be 3G. (Rolf, 3:21-25, 13:13-15.) Likewise, nothing in
`
`Gatherer limits the applicability of DSPs to 2G systems. Although Gatherer
`
`discusses the use of DSPs in 2G/GSM systems in existence at the time of its
`
`4
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`publication, Gatherer also provides extensive discussion on the use of DSPs in 3G
`
`Case IPR2017-00550
`Patent 9,037,502
`
`
`
`
`systems. (E.g., Gatherer, p.85 (“With the advent of wireless data applications and
`
`the increased bandwidth of 3G, we expect this trend to accelerate.”), p.86 (“As the
`
`industry shifts from second-generation to 3G wireless we see the percentage of the
`
`physical layer MIPS that reside in the DSP going from essentially 100 percent in
`
`today’s technology for GSM to about 10 percent for wideband code-division
`
`multiple access (WCDMA).” (emphasis added)), p.87 (“In this section we discuss
`
`how coprocessors can complement the function of programmable DSPs in the
`
`implementation of a flexible 3G platform.”) (emphasis added), p.89, (“We estimate
`
`that to support 240 3G voice channels… would require a 45K gate coprocessor and
`
`only 6 MHz of DSP processing on a C6x.”).) As such, far from dissuading a person
`
`of ordinary skill from using a DSP with the cell phone of Rolf, Gatherer’s extensive
`
`discussion on the use of DSPs for future 3G technology provides a further motivation
`
`to combine with a 3G-compatible system. Thus, in attempting to draw a false
`
`distinction between the technologies in Rolf and Gatherer, the Patent Owner has
`
`highlighted yet another express motivation to combine.2
`
`
`2 Indeed, even the very sentence from Gatherer the Patent Owner cites to argue that
`
`“the application of GSM principles to 3G technology is ‘debatable’” (Response, at
`
`30), Gatherer goes on to suggest the existence of a close kinship between GSM and
`
`5
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`
`
`
`
`Case IPR2017-00550
`Patent 9,037,502
`
`The Patent Owner further asserts that because “Gatherer does not explain the
`
`relationship between a digital signal processor and the remaining parts of the cell
`
`phone, or how a digital signal processor would be integrated into the device
`
`disclosed by Rolf,” Petitioners have not “argued why Rolf and Gatherer combined
`
`fully disclose this claim element” and “have failed to prove the claim is obvious.”
`
`(Response, at 29-30.) But the Petition provided an extensive explanation of how the
`
`DSP limitation is rendered obvious by Rolf and Gatherer. (Petition, at 27-30.) And
`
`as the panel in a related proceeding emphasized in response to a similar argument
`
`by the Patent Owner, “the challenged claims do not recite an explicit integration of
`
`the claimed DSP with any other user device elements.” (IPR2017-00687, Paper 9,
`
`at 14.) The law thus does not require a detailed explanation of how the DSP in
`
`Gatherer would be bodily or physically incorporated into the cell phone circuitry in
`
`Rolf. Allied Erecting & Dismantling Co. v. Genesis Attachments, LLC, 825 F.3d
`
`1373, 1381 (Fed. Cir. 2016) (“The test for obviousness is not whether the features
`
`
`3G technology with respect to the use of DSPs in cellular telephony. (Gatherer, p.84,
`
`(“The assumption is, of course, that third-generation cellular (3G) products will
`
`evolve in a similar manner to GSM, which is in itself debatable, but we believe that
`
`history does have some good points to make with respect to 3G.”) (emphasis
`
`added).)

`of a secondary reference may be bodily incorporated into the structure of the primary
`
`Case IPR2017-00550
`Patent 9,037,502
`
`
`
`
`reference but rather whether a skilled artisan would have been motivated to combine
`
`the teachings of the prior art references to achieve the claimed invention.”) (internal
`
`quotations and citations omitted)).
`
`Further, the Patent Owner’s assertion that “Gatherer does not explain the
`
`relationship between a digital signal processor and the remaining parts of the cell
`
`phone, or how a digital signal processor would be integrated into the device
`
`disclosed by Rolf” (Response, at 29-30) is simply false. For example, Gatherer
`
`provides “[a] functional block diagram of a GSM phone” in Figure 1, reproduced
`
`below.
`
`(Gatherer, p.85 (Fig. 1).) This block diagram depicts the relationship between the
`
`DSP and other parts of a cell phone, and identifies the cell phone functions
`
`
`
`7
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`performed by the DSP. Indeed, a primary focus of the Gatherer reference is to
`
`Case IPR2017-00550
`Patent 9,037,502
`
`
`
`
`explore the relationship between the DSP and wireless handsets and all the different
`
`ways that DSPs had been, and could be, integrated into cell phones. (E.g., id., p.84.)
`
`The Patent Owner further argues that “Petitioners have not provided sufficient
`
`evidence that one of skill would have a reasonable expectation of success that the
`
`proposed combination would work.” (Response, at 31.) This argument ignores the
`
`extensive explanation that the Petition provided on this subject. The Petition
`
`explained, for example, that DSPs were widely-available, off-the-shelf components
`
`that had already been incorporated into cellular phones. (Petition, at 28-29 (citing
`
`Lavian, ¶93).) Dr. Lavian explained in his unrebutted declaration that off-the-shelf
`
`DSPs had existed since at least the early 1980s, and that “[b]y the time of the alleged
`
`invention, DSPs were standard components in cell phones.” (Lavian, ¶¶27, 29.) Dr.
`
`Lavian also cited several contemporaneous publications (in addition to Gatherer)
`
`demonstrated that DSPs had already been deployed for precisely the purposes
`
`contemplated by the claims. (Id., ¶¶28, 29.) Dr. Lavian explained that the prior art
`
`references cited in the combination provided sufficient detail to allow the
`
`combination to be practiced without undue experimentation, and that one of ordinary
`
`skill certainly “could have done so, due to the maturity of those technologies” and
`
`the fact that the technologies were “well-known” and “subject of extensive public
`
`documentation.” (Id., ¶¶140, 143, 145.) Indeed, Gatherer explains in detail how
`
`8
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`DSPs could be—and historically had been—successfully (in fact, “pervasive[ly]”)
`
`Case IPR2017-00550
`Patent 9,037,502
`
`
`
`
`included in cell phones. (E.g., Gatherer, Abstract (“Programmable DSPs are
`
`pervasive in the wireless handset market for digital cellular telephony.”).) In sum,
`
`the record contains overwhelming evidence that the combination of Rolf and
`
`Gatherer would have been successful. The Patent Owner tellingly submitted no
`
`evidence to the contrary.
`
`B.
`“OFDM”
`The Patent Owner’s arguments with respect to the OFDM limitation do little
`
`more than rehash the same arguments rejected by the Board’s decision in IPR2014-
`
`01236, which the Federal Circuit affirmed in Skky, Inc. v. MindGeek, S.A.R.L., 859
`
`F.3d 1014 (Fed. Cir. 2017). As the Board observed, “in MindGeek, the Board and
`
`the Federal Circuit similarly concluded that it would have been obvious to utilize
`
`OFDM for Rolf’s system of delivering music files to a cellular telephone.”
`
`(Institution Decision, at 10.)
`
`Undeterred by its previous failures, the Patent Owner again argues that there
`
`would have been no motivation to apply an OFDM transmission scheme to Rolf.
`
`But this time, the Patent Owner offers no expert testimony or other evidence to
`
`support its arguments. The gist of the Patent Owner’s argument is:
`
`Rolf and Frodigh are premised on two entirely different systems of
`network communication. The invention in Rolf relies on a 3G mobile
`network which uses Code Division Multiple Access (CDMA), not
`
`9
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`
`
`
`
`Case IPR2017-00550
`Patent 9,037,502
`
`OFDM. Frodigh teaches an allocation method specifically directed to
`OFDM and is not applicable to 3G. Thus, a person of ordinary skill
`would not be motivated to combine the two references.
`
`This is especially true because, in the late 1990s, persons of
`extraordinary skill in the art chose CDMA, and rejected OFDM, for use
`in the 3G standard.
`
`(Response, at 32 (citation omitted); see also id. at 35.)3
`
`There are a number of flaws with the Patent Owner’s argument. As this Board
`
`has found (and discussed further above), there is “no basis to suggest that the skilled
`
`
`3 These arguments are substantially identical to the arguments previously presented
`
`and rejected by the Board and Federal Circuit in MindGeek. (See IPR2014-01236,
`
`Paper 21, Ex. 1070, at 53 (“Rolf explicitly teaches the use of 3G modulation
`
`protocols instead of OFDM. Indeed, the standards setting organization that created
`
`the 3G standard considered, and ultimately rejected, using OFDM in 3G. Because
`
`3G does not use an OFDM modulation scheme, Rolf teaches away from the process
`
`in OFDM/FM.... Given that the modulation schemes of OFDM and 3G were not
`
`compatible and that OFDM was rejected during the creation of 3G, these references
`
`teach away from the proposed combination by Petitioners.”) (citations omitted);
`
`Appellant Skky, Inc.’s Correct Opening Brief, Ex. 1071, at 67 (similar arguments);
`
`Appellant Skky, Inc.’s Reply Brief, Ex. 1072, at 33-34 (similar arguments).)
`
`10
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`artisan would understand that Rolf’s system could only be implemented on a
`
`Case IPR2017-00550
`Patent 9,037,502
`
`
`
`
`3G/CDMA cellular network.” (Institution Decision, at 14 (emphasis in original).)
`
`Moreover, as the panel in a related proceeding has articulated in response to this
`
`same argument by the Patent Owner, “persons of extraordinary skill in the art do not
`
`provide the proper frame of reference from which to view obviousness.” (IPR2017-
`
`00687, Paper 9, at 15 (quotation marks omitted; emphasis added).) And as this
`
`Board observed, “the evidence cited by Patent Owner regarding the SMG’s decision
`
`to use CDMA in the 3G standard indicates that there were advantages and drawbacks
`
`to both OFDM and CDMA.” (Institution Decision, at 9 (citing Ex. 2004, 1-4).)
`
`In fact, the documents submitted by the Patent Owner relating to the SMG’s
`
`decision (which are unauthenticated and inadmissible) further support Petitioners’
`
`rationale that OFDM, as a “multiple access” scheme, would have been obvious to
`
`try. (Petition, at 32.) For example, one document cited by the Patent Owner states
`
`that OFDM modulation is “robust[]” and “performs well in all kind [sic] of
`
`environments, and could be quite efficient in presence of large delay spread.”
`
`(Ex. 2004, at 1.) Although the document states that CDMA was eventually chosen,
`
`the evaluation and comparison of different multiple access schemes, including
`
`OFDM, WB-TDMA, TD/CDMA, and W-CDMA (Ex. 2004, at 1-4), confirms that
`
`OFDM would have been obvious to try because it was one of a finite number of
`
`11
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`identified, predictable solutions, and that its application to a cellular system would
`
`Case IPR2017-00550
`Patent 9,037,502
`
`
`
`
`have had a reasonable expectation of success. (Petition, at 32; Lavian, ¶99.)
`
`The Patent Owner has also baselessly asserted that “Petitioners have not
`
`provided sufficient evidence that one of skill would have a reasonable expectation
`
`of success that the proposed combination would work.” (See Response, at 31.)
`
`Indeed, the Petition explained that “a person of ordinary skill in the art would have
`
`had every expectation of success in combining Frodigh with Rolf in the manner
`
`described above,” referring to the extensive analysis provided earlier in the Petition.
`
`(Petition, at 32; Lavian, ¶99.) The Petition explained that the use of OFDM as a
`
`transmission scheme dates back to the 1960s, and by 2001, was well-known.
`
`(Petition, at 15 (citing Lavian, ¶35).) The accompanying declaration of Dr. Lavian
`
`identified nearly two dozen references dated prior to June 2001 describing the use
`
`of OFDM in cellular or wireless communication systems. (Lavian, ¶¶36-39; see also
`
`Petition, at 15-16.) One of those references, entitled “Multi-Carrier Digital
`
`Communications: Theory and Applications of OFDM,” stated in no ambiguous
`
`terms that “OFDM has been particularly successful in numerous wireless
`
`applications.” (Ex. 1030, p.14 (emphasis added); see also Petition, at 16 (quoting
`
`Ex. 1030); Lavian, ¶37 (same).) Dr. Lavian also explained that Rolf and Frodigh
`
`provide sufficient detail to allow the combination to be practiced without undue
`
`experimentation, and that one of ordinary skill in the art certainly “could have done
`
`12
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`so, due to the maturity of those technologies” and the fact that the technologies were
`
`Case IPR2017-00550
`Patent 9,037,502
`
`
`
`
`“well-known” and “subject of extensive public documentation.” (Lavian, ¶¶140,
`
`143, 145.)
`
`The record is thus replete with evidence that a person of ordinary skill in the
`
`art would have had every expectation that Rolf and Frodigh could have been
`
`successfully combined, and the Patent Owner has submitted no evidence showing
`
`otherwise.
`
`The Patent Owner’s remaining arguments attempt to impermissibly attack
`
`Frodigh individually, ignoring its combination with other references. See In re
`
`Merck & Co., Inc., 800 F.2d 1091, 1097 (Fed. Cir. 1986) (“Non-obviousness cannot
`
`be established by attacking references individually where the rejection is based upon
`
`the teachings of a combination of references.”); Soft Gel Techs., Inc. v. Jarrow
`
`Formulas, Inc., 864 F.3d 1334, 1341 (Fed. Cir. 2017). For example, the Patent
`
`Owner characterizes “[t]he goal in the Frodigh system” as “to provide fewer dropped
`
`calls and calls with better quality,” and thus argues that “Frodigh is not relevant to
`
`the claimed method.” (Response, at 31-32.) But, as the Board has stated in a related
`
`case in response to this same argument by the Patent Owner, “[e]ven if correct, the
`
`fact that Frodigh is directed to solving a different problem does not discount
`
`Petitioner’s asserted motivation for making the combination or prevent its usage in
`
`an obviousness combination with Rolf. Prior art references must be considered as a
`
`13
`
`

`

`Atty Docket No. FABO-055/00US
`(309101-2151)
`
`whole for all that they teach, regardless of the specific problems to which they are
`
`Case IPR2017-00550
`Patent 9,037,502
`
`
`
`
`directed.” (IPR2017-00089, Paper 7, at 14.) Frodigh describes in detail the use of
`
`OFDM modulation for cellular systems and its advantages, and further recognized
`
`that “data,” in addition to “voice,” can be received by a mobile device over the
`
`cellular connection. (Petition, at 29-32 (citing Frodigh, 1:59-2:18, 7
