`
`PETITIONER’S REPLY TO PATENT OWNER’S
`PRELIMINARY RESPONSE
`
`
`
`IPR2020-00033
`U.S. Patent No. 8,023,580
`
`Petitioner demonstrated a reasonable likelihood that at least one challenged
`
`claim is unpatentable. PO’s plea for the Board to exercise discretion under §325(d)
`
`and §314(a) should be rejected because PO mischaracterizes the record and places
`
`undue reliance on a single factor in multi-factor balancing tests. Trial Practice Guide
`
`(Nov. 2019) (“TPGU”), 58 (When considering and exercising discretion in
`
`instituting IPR, the Board conducts a “balanced assessment of all relevant
`
`circumstances in the case, including the merits.”).
`
`I. PO’S CONFLICTING POSITIONS DEMAND REVIEW
`
`PO’s §325(d) arguments mischaracterize the record. POPR 40-45. No
`
`reference at issue in this IPR was addressed by the Examiner during prosecution. To
`
`insist otherwise, PO wrongly contends that “Siwiak ’398 expressly describes the
`
`very aspects of Siwiak ’306 that Petitioner relies on including, e.g., the ‘different
`
`types’ of modulation.” POPR 43. Contrary to PO, Siwiak ’398 does not describe the
`
`FSK and QAM modulations taught by Siwiak ’306, and, in fact, PO represented as
`
`much to the Examiner to secure allowance of its claims. Pet. 7.
`
`As PO explained in litigation and reexamination, to overcome a rejection
`
`based on Siwiak ’398 during the original prosecution, Applicant amended the claims
`
`to require different “types” of modulation, and identified “the FSK family” and “the
`
`QAM family” as examples. Rembrandt v. Apple, 19-cv-00025, D.I. 73 at 9 (E.D.
`
`Tex. Oct. 21, 2019); Ex. 1010, 756-758; Ex. 1002, 140. PO represented to the district
`
`1
`
`
`
`
`IPR2020-00033
`U.S. Patent No. 8,023,580
`
`court that this amendment distinguished Siwiak ’398’s disclosure of FM and OFDM
`
`because those are “‘different’ modulation methods of the same frequency ‘type.’”
`
`Rembrandt, 19-cv-00025, D.I. 73 at 6. Thus, to secure allowance during prosecution,
`
`PO represented that Siwiak ’398 does not teach “different types”—such as FSK and
`
`QAM. Id. But now, to avoid IPR, PO argues the opposite—that, by incorporating
`
`Siwiak ’306 by reference, Siwiak ’398 does teach “different types” of modulation
`
`methods, including FSK and QAM. POPR 43; see Pet. 55-60. Far from justifying
`
`§325(d) discretionary denial, PO’s contradictory positions underscore
`
`the
`
`importance of institution.
`
`Moreover, balancing all the Becton factors weighs in favor of institution.
`
`IPR2017-01586, Paper 8. Here, unlike in NHK, there are no §325(d) issues based on
`
`art previously considered by the Office. Four of the five references were not cited at
`
`all (Pet. 7), and as discussed above, the critical disclosures of FSK and QAM in
`
`Siwiak ’306 were not addressed during examination nor the basis of a rejection. PO
`
`has put forth no credible basis for suggesting that the art advanced by Petitioner is
`
`cumulative of the art of record. Indeed, as with Siwiak ’306, Briancon (incorporating
`
`Leitch by reference) expressly discloses two “different types” of modulation, FSK
`
`and QAM, whereas Siwiak ’398 does not. Pet. 26-27.

`
`II. §314(a) DISCRETION IS NOT WARRANTED
`
`PO ignores critical differences between the IPR grounds and claim
`
`construction issues asserted here and in the district court, and fails to demonstrate
`
`that instituting IPR would result in a waste of judicial resources.
`
`PO fails to tell the Board that it has requested new claim constructions here
`
`on terms it previously told the district court “do not require construction.” Compare
`
`POPR 23-31 with Ex. 2009, 7. Moreover, Ground 2 here relies on US 5,521,926 to
`
`Ayerst, while the court contentions rely on a different Ayerst patent with a different
`
`disclosure, US 5,644,568. Pet. 51-55; Ex. 2007, ¶¶78-80. Both parties rely on
`
`different experts here and in the litigation. And the district court case includes
`
`multiple grounds of invalidity including §§101 and 112, and unique grounds under
`
`§§102 and 103 not at issue here, potentially enabling limited trial time to focus on
`
`different invalidity defenses. Ex. 2007, e.g., 91-177. Given all of these significant
`
`differences between the IPR and litigation, §314(a) does not warrant denial.
`
`Further, there is no guarantee the court will actually get to final judgment
`
`before the FWD. IPR2019-01044, Paper 17, *14 (“District court litigation is not
`
`subject to fixed, immutable deadlines for final disposition”). Additionally, the
`
`pending mandamus petition to stay or transfer the litigation may ultimately be
`
`granted, delaying the time to trial. In re: Apple Inc., 2020-112 (Fed. Cir.). Thus, the
`
`time to trial (in the context of all of the other factors outlined in General Plastic and
`
`3
`
`
`
`
`IPR2020-00033
`U.S. Patent No. 8,023,580
`
`Becton) does not weigh in favor of discretionary denial.
`
`Consideration of discretion under §314(a) requires a “balanced assessment of
`
`all relevant circumstances in the case, including the merits.” TPGU, 58. Contrary to
`
`PO’s arguments, while the NHK case permits the Board to consider the stage of a
`
`parallel district court litigation, it “should do so in the context of all the other factors,
`
`such as those outlined in General Plastic…and Becton, Dickinson.” IPR2018-
`
`01354, Paper 8, *36. Here, GP factors 1-5 and 7 favor institution, as this is
`
`Petitioner’s first petition challenging this patent. In addition, there has been no ruling
`
`in the co-pending litigation giving Petitioner a road map on how to improve its case,
`
`and PO identifies none. Finally, where the Petition presents a strong case of
`
`patentability, as here, the stage of the litigation should not outweigh the merits. See,
`
`e.g., IPR2019-01000, Paper 10, *40-49 (“we determine that the merits of the
`
`challenges presented in the Petition strongly outweigh any concerns about inefficient
`
`use of resources”).
`
`Contrary to PO’s argument (POPR 40), Petitioner did not delay and secured
`
`no unfair benefit from the timing of its filing. See id., *47-48. The Petition was filed
`
`well within the statutory framework. IPR2018-01689, Paper 15, *59 (filing within
`
`§315(b) period “presumptively proper”). Petitioner had no pre-suit notice and
`
`worked diligently from the time of filing to review the long history of the ’580 patent
`
`(see Pet. 12-14), understand PO’s infringement contentions, identify prior art, and
`
`4
`
`
`
`
`IPR2020-00033
`U.S. Patent No. 8,023,580
`
`prepare the Petition for filing. Additionally, given the Philips standard at issue here,
`
`it was appropriate for Petitioner to file the Petitions shortly after the PO committed
`
`to its claim constructions in the district court (a commitment it did not keep in these
`
`proceedings). Pet. 16. Petitioner should not be penalized here because the court set
`
`an initial trial date within 18 months of the Complaint.
`
`PO’s cases are inapposite. Unlike here, the district court in E-One already
`
`assessed the merits of the challenges presented and found them lacking. IPR2019-
`
`00161, Paper 16, *8-9. Likewise, Magellan involved multiple petitions by the same
`
`Petitioner spaced out in time; here Apple filed its Petitions together and without
`
`delay. IPR2019-01445, Paper 12, *11-12. Unlike Sand Revolution, PO here presents
`
`new claim construction positions that it failed to raise before the district court and
`
`may not ever be considered by the court. IPR2019-01393, Paper 12, *17, 20-21
`
`(dissent). And unlike Uniloc, here there is no printed publication issue and there are
`
`significant differences between the pending IPR and litigation. IPR2019-01219,
`
`Paper 7, *16.
`
`Accordingly, PO presents no basis for denial, and the Board should institute.
