`
`DECISION
`Granting Institution of Inter Partes Review
`35 U.S.C. § 314
`
`Apple Inc. (“Petitioner”) filed a Petition (Paper 1, “Pet.”) requesting
`
`an inter partes review (“IPR”) of claims 2, 5, 6, and 12–15 (“the challenged
`
`claims”) of U.S. Patent No. 6,928,306 B2 (Ex. 1001, “the ’306 patent”).
`
`Petitioner filed a Declaration of Michael Kotzin, Ph.D. (Ex. 1006) with its
`
`Petition. Patent Owner, Maxell, Ltd. (“Patent Owner”), filed a Preliminary
`
`Response (Paper 6, “Prelim. Resp.”).

`
`IPR2020-00204
`Patent 6,928,306 B2
`
`With our authorization (Paper 7), Petitioner also filed a Reply
`
`(Paper 8, “Pet. Reply”) and Patent Owner filed a Sur-Reply (Paper 10, “PO
`
`Sur-reply”) addressing whether we should exercise our discretion to deny
`
`institution under 35 U.S.C. § 314(a).
`
`We have authority to determine whether to institute an inter partes
`
`review. See 35 U.S.C. § 314(b); 37 C.F.R. § 42.4(a). Under 35 U.S.C.
`
`§ 314(a), we may not authorize an inter partes review unless the information
`
`in the petition and the preliminary response “shows that there is a reasonable
`
`likelihood that the petitioner would prevail with respect to at least 1 of the
`
`claims challenged in the petition.” For the reasons that follow, we institute
`
`an inter partes review as to claims 2, 5, 6, and 12–15 of the ’306 patent on
`
`all grounds of unpatentability presented.
`
`
`
`
`
`I. BACKGROUND
`
`A.
`
`Real Parties-in-Interest
`
`Petitioner identifies Apple Inc. as the real party-in-interest. Pet. 48.
`
`Patent Owner identifies Maxell, Ltd. as the real party-in-interest. Paper 4, 1.
`
`
`
`B.
`
`Related Proceedings
`
`The parties identify the following proceedings related to the
`
`’306 patent (Pet. 43, 48; Paper 4, 1):
`
`Maxell, Ltd. v. Apple Inc., No. 5:19-cv-00036 (E.D. Tex. Mar. 15,
`
`2019) (“the underlying litigation”); and
`
`Huawei Techs. Co. v. Maxell, Ltd., IPR2019-00640 (settled prior to
`
`institution decision) (“the ’640 IPR”).

`
`IPR2020-00204
`Patent 6,928,306 B2
`
`In the ’640 IPR, Patent Owner identified two other proceedings
`
`related to the ’306 patent (IPR2019-00640, Paper 4, 1):
`
`Maxell, Ltd. v. Huawei Device USA, Inc., No. 5:18-cv-00033 (E.D.
`
`Tex. Mar. 2, 2018); and
`
`Maxell, Ltd. v. ZTE Corp., No. 5:18-cv-00034 (E.D. Tex. Mar. 2,
`
`2018).
`
`
`
`C.
`
`The ’306 patent
`
`The ’306 patent is directed to a portable mobile unit that alerts a user
`
`of an incoming call using a ringing sound. Ex. 1001, 1:6–10. Figure 1 of
`
`the ’306 patent is reproduced below.
`
`Figure 1 depicts a communication controller and ringing sound generator of
`
`a cellular phone. Id. at 2:59–61, 4:34–36. The ringing sound generator
`
`includes frequency modulation (FM) sound data memory 3a, pulse-code
`
`modulation (PCM) sound data memory 3b of a sound source, and Musical
`

`
`IPR2020-00204
`Patent 6,928,306 B2
`
`Instrument Digital Interface (MIDI) method sound data memory 3c. Id. at
`
`4:41–44. Each of these memories has corresponding sound data
`
`reproduction portions 4a, 4b, and 4c, respectively, connected to controller 2.
`
`Id. at 4:44–53. Controller 2 determines the timing for reproducing selected
`
`sound data based on data in reproduction timing memory 1. Id. at 4:53–59.
`
`Outputs of the respective sound reproduction portions 4a, 4b, and 4c are
`
`connected to a mixer 5, which outputs ringing sounds to speaker 6. Id. at
`
`4:59–65.
`
`The pattern of a ringing sound may be changed based on a range of
`
`time1 (e.g., from “midnight to the early morning,” a day of the week, or
`
`holidays) during which a call is received. Id. at 9:62–10:64, Figs. 5, 6.
`
`The ’306 patent issued from an application that was filed January 4,
`
`2001, which claims priority to a Japanese patent application filed on
`
`January 7, 2000. Id., codes (22), (30). As discussed below, Petitioner
`
`attempts to establish that, at a minimum, its asserted references qualify as
`
`prior art relative to either the January 7, 2000, filing date of the Japanese
`
`application (i.e., the earliest possible effective filing date) or the January 4,
`
`2001, filing date of the U.S. application.
`
`
`
`
`1 The ’306 patent refers to ranges of time as “time zones.” See, e.g.,
`Ex. 1001, 10:24–28. Petitioner asks us to make a “clarifying construction”
`that “‘time zone’ . . . indicate[s] a duration of time or range of hours, rather
`than one of 24 zones on the earth.” Pet. 7 (citing Ex. 1001, 10:35–40).
`Although we agree with Petitioner’s interpretation, we need not
`affirmatively construe “time zone” given that the asserted prior art (Miura)
`uses the same term in the same manner. See, e.g., Ex. 1005, 7:37–46.

`
`D.
`
`Illustrative Claim
`
`Of the challenged claims, claims 2, 12, and 13 are independent.
`
`Claims 5 and 6 depend from claim 2, and claims 14 and 15 depend from
`
`claim 13. Claim 2 is illustrative of the challenged claims and recites:
`
`A portable mobile unit capable of alerting on incoming of
`2.
`a signal by a ringing sound, comprising:
`
`a ringing sound generator having a plurality of sound
`sources therewith; and
`
`a controller for controlling operations of said portable
`mobile unit, wherein
`
`said controller controls said ringing sound generator so as
`to generate the ringing sound using at least two of said sound
`sources when the signal comes in.
`
`Ex. 1001, 17:38–46.
`
`
`
`E.
`
`Prior Art
`
`Petitioner relies on the following prior art:
`
`Patent Cooperation Treaty (PCT) Patent Application
`Publication No. WO 96/27974, published Sept. 12, 1996
`(Ex. 1003, “Van der Salm”);
`
`Chinese Patent Publication No. CN 1190303A, published
`Aug. 12, 1998 (Ex. 1004, “Huang”);2 and
`
`U.S. Patent No. 6,763,105 B1, filed Nov. 13, 1998, issued
`July 13, 2004 (Ex. 1005, “Miura”).
`
`
`
`
`2 Huang is a Chinese-language publication (Ex. 1004, 13–22) that was filed
`with an English-language translation (id. at 1–11) and a declaration attesting
`to the accuracy of the translation (id. at 12). Our citations to Huang herein
`refer to the translation. We follow Petitioner’s convention of referencing the
`page numbers added to the footer of Huang.

`
`
`
`II. ANALYSIS
`
`We now consider Petitioner’s asserted grounds and Patent Owner’s
`
`arguments in the Preliminary Response to determine whether Petitioner has
`
`met the “reasonable likelihood” standard for institution under 35 U.S.C-
`
`§ 314(a).
`
`A.
`
`Legal Standards
`
`A claim is unpatentable under 35 U.S.C. § 103(a) if the differences
`
`between the claimed subject matter and the prior art are such that the subject
`
`matter, as a whole, would have been obvious at the time the invention was
`
`made to a person having ordinary skill in the art to which said subject matter
`
`pertains- See KSR Int’l Co. v. Teleflex Inc_, 550 US. 398, 406 (2007).
`
`3 The Leahy—Smith America Invents Act (“AIA”), Pub. L. No. 112-29, 125
`Stat. 284, 287—88 (2011), amended 35 U.S-C. §§ 102, 103, and 112.
`Because the ’306 patent was filed before March 16, 2013 (the effective date
`of the relevant amendments), the pre-AIA versions of §§ 102, 103, and 112
`apply.
`
`4 Petitioner asserts this ground under an alternative construction for the term
`“ringing sound generator.” Pet. 5, 39; see infra note 5.
`
`
`
`Case 5:19-cv-00036-RWS Document 485-6 Filed 08/05/20 Page 8 of 35 PageID #: 26501
`
`IPR2020-00204
`Patent 6,928,306 B2
`
`The question of obviousness is resolved on the basis of underlying factual
`
`determinations, including (1) the scope and content of the prior art; (2) any
`
`differences between the claimed subject matter and the prior art; (3) the level
`
`of skill in the art; and (4) where in evidence, so-called secondary
`
`considerations. See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966).
`
`We also recognize that prior art references must be “considered together
`
`with the knowledge of one of ordinary skill in the pertinent art.” In re
`
`Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994) (citing In re Samour, 571 F.2d
`
`559, 562 (CCPA 1978)).
`
`
`
`B.
`
`Level of Ordinary Skill in the Art
`
`Citing testimony from Dr. Kotzin, Petitioner contends a person having
`
`ordinary skill in the art would have had “a Bachelor’s degree in Electrical
`
`Engineering, Computer Engineering, or Computer Science, or an equivalent
`
`degree with at least 2 years of experience in consumer telephony products,
`
`human-computer interaction, or related technologies.” Pet. 4 (citing
`
`Ex. 1006 ¶¶ 31–33). Patent Owner contends an ordinarily skilled artisan
`
`would have had “a Bachelor of Science Degree in Electrical/Computer
`
`Engineering or Computer Science or an equivalent degree, and at least two
`
`years of experience working in the field of audio signal processing.” Prelim.
`
`Resp. 21. Patent Owner does not cite any evidence in support of its
`
`contention. See id.
`
`Both parties agree on the type of formal schooling and the number of
`
`years’ experience an ordinarily skilled artisan would have had, but they
`
`differ on how they characterize the field of the experience. We adopt
`
`Petitioner’s characterization that an ordinarily skilled artisan would have had
`

`
`
`
`Case 5:19-cv-00036-RWS Document 485-6 Filed 08/05/20 Page 9 of 35 PageID #: 26502
`
`IPR2020-00204
`Patent 6,928,306 B2
`
`experience in “consumer telephony products, human-computer interaction,
`
`or related technologies” because it is backed by Dr. Kotzin’s testimony (see
`
`Ex. 1006 ¶ 32), whereas Patent Owner’s contention is not backed by any
`
`evidence. Accordingly, for purposes of this Decision, we adopt Petitioner’s
`
`definition of the level of ordinary skill in the art. On the present record, we
`
`are satisfied that this definition comports with the level of skill necessary to
`
`understand and implement the teachings of the ’306 patent and the asserted
`
`prior art. Notwithstanding, our findings and conclusions would be the same
`
`under either party’s definition of the level of ordinary skill in the art.
`
`
`
`C.
`
`Claim Interpretation
`
`In an inter partes review, we construe each claim “in accordance with
`
`the ordinary and customary meaning of such claim as understood by one of
`
`ordinary skill in the art and the prosecution history pertaining to the patent.”
`
`37 C.F.R. § 42.100(b) (2019). Accordingly, our claim construction standard
`
`is the same as that of a district court. See id. Under the standard applied by
`
`district courts, claim terms are generally given their plain and ordinary
`
`meaning as would have been understood by a person of ordinary skill in the
`
`art at the time of the invention and in the context of the entire patent
`
`disclosure. Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005)
`
`(en banc). “There are only two exceptions to this general rule: 1) when a
`
`patentee sets out a definition and acts as his own lexicographer, or 2) when
`
`the patentee disavows the full scope of a claim term either in the
`
`specification or during prosecution.” Thorner v. Sony Comput. Entm’t Am.
`
`LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012).
`
`8
`
`
`
`Case 5:19-cv-00036-RWS Document 485-6 Filed 08/05/20 Page 10 of 35 PageID #: 26503
`
`IPR2020-00204
`Patent 6,928,306 B2
`
`Construing a claim term under 35 U.S.C. § 112 ¶ 6 involves two steps:
`
`identifying the claimed function and then determining what structure, if any,
`
`disclosed in the specification corresponds to the claimed function.
`
`Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1351 (Fed. Cir. 2015). To
`
`determine whether § 112 ¶ 6 applies to a claim limitation, the essential
`
`inquiry is “whether the words of the claim are understood by persons of
`
`ordinary skill in the art to have a sufficiently definite meaning as the name
`
`for structure.” Id. at 1348. If the limitation uses the word “means,” “there is
`
`a rebuttable presumption that § 112, para. 6 applies; if not, there is a
`
`rebuttable presumption that the provision does not apply.” Diebold Nixdorf,
`
`Inc. v. Int’l Trade Comm’n, 899 F.3d 1291, 1298 (Fed. Cir. 2018).
`
`
`
`1.
`
`“Ringing Sound Generator” (Claims 2, 5, 6, and 12–15)
`
`Petitioner contends the term “ringing sound generator” recited in
`
`claims 2, 5, 6, and 12–15 should be construed under § 112 ¶ 6. Pet. 6–11.
`
`Petitioner contends the claimed function differs based on differences in the
`
`language of these claims. See id. at 7. For example, Petitioner contends the
`
`claimed function for claim 2 is “generat[ing] the ringing sound ‘using at
`
`least two of said sound sources.’” Id. Petitioner further contends the
`
`corresponding structure is ringing sound generator 1519 comprising “sound
`
`data of sound sources 3a-3c, sound data reproduction portion of sound
`
`sources 4a-4c, and reproduction timing memory 1.” Id. at 9.
`
`Patent Owner argues, inter alia, that “the term ‘ringing sound
`
`generator’ does not use ‘means for’ or ‘step for’ language, and therefore it is
`
`presumed that §112 ¶ 6 does not apply.” Prelim. Resp. 24 (citing
`
`Williamson, 792 F.3d at 1348; Masco Corp. v. United States, 303 F.3d 1316,
`
`9
`
`
`
`Case 5:19-cv-00036-RWS Document 485-6 Filed 08/05/20 Page 11 of 35 PageID #: 26504
`
`IPR2020-00204
`Patent 6,928,306 B2
`
`1326 (Fed. Cir. 2002)). Patent Owner also notes that Petitioner does not
`
`argue that “‘generator’ or any other term in the phrase ‘ringing sound
`
`generator’ is a ‘nonce’ word requiring §112 ¶ 6 treatment.” Id. Patent
`
`Owner additionally notes that the court in the underlying litigation did not
`
`treat “ringing sound generator” under § 112 ¶ 6. Id. at 24 (citing Ex. 2008,
`
`25–28).
`
`We agree with Patent Owner that Petitioner does not explain why the
`
`term “ringing sound generator” should be governed by § 112 ¶ 6. As noted
`
`by Patent Owner, the lack of the word “means” creates a rebuttable
`
`presumption that § 112 ¶ 6 does not apply. See Diebold, 899 F.3d at 1298.
`
`Petitioner presents no arguments or evidence to rebut that presumption. We
`
`further note that the court in the underlying litigation construed the term
`
`“ringing sound generator” to have its plain and ordinary meaning. Ex. 2008,
`
`28. The court reasoned that a “ringing sound generator” connotes structure
`
`in the specification of the ’306 patent. Id. at 26. In particular, the court
`
`found that “Figure 15 depicts the ringing sound generator as a component in
`
`the ‘circuit constructions of the cellular phone’ where it is connected to a
`
`communication controller and a speaker.” Id. (citing Ex. 1001, 15:50–51,
`
`Fig. 15). We agree with the court’s analysis, and, for purposes of this
`
`Decision, we apply the plain and ordinary meaning.5
`
`
`
`
`5 Petitioner puts forth an alternate construction for “ringing sound generator”
`under § 112 ¶ 6 that forms the basis of its alternative obviousness ground
`based on Van der Salm, Huang, and Miura. See Pet. 11, 39–41. We are not
`persuaded by Petitioner’s alternative construction for the same reasons
`discussed above.

`
`IPR2020-00204
`Patent 6,928,306 B2
`
`2.
`
`Other Terms
`
`Based on the current record, we determine that no other terms require
`
`explicit construction. See, e.g., Nidec Motor Corp. v. Zhongshan Broad
`
`Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“[W]e need only
`
`construe terms ‘that are in controversy, and only to the extent necessary to
`
`resolve the controversy’ . . . .” (quoting Vivid Techs., Inc. v. Am. Sci. &
`
`Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))).
`
`
`
`D.
`
`Patent Owner’s Arguments Regarding Discretionary Denial
`
`Patent Owner contends we should exercise our discretion to deny
`
`institution under 35 U.S.C. § 314(a) based on the duplicative nature and
`
`advanced stage of the underlying litigation. Prelim. Resp. 2–20; PO
`
`Sur-reply 1–10. Petitioner contends it filed its Petition timely and that there
`
`is little overlap with the underlying litigation. Pet. 43–47; Pet. Reply 1–10.
`
`Institution of inter partes review is discretionary. Harmonic Inc. v.
`
`Avid Tech., Inc., 815 F.3d 1356, 1367 (Fed. Cir. 2016) (“[T]he [Office] is
`
`permitted, but never compelled, to institute an [inter partes review]
`
`proceeding.”); 35 U.S.C. § 314(a) (“The Director may not authorize an inter
`
`partes review to be instituted unless the Director determines that the
`
`information presented in the petition filed under section 311 and any
`
`response filed under section 313 shows that there is a reasonable likelihood
`
`that the petitioner would prevail with respect to at least 1 of the claims
`
`challenged in the petition.” (emphasis added)). In Apple Inc. v. Fintiv, Inc.,
`
`IPR2020-00019, Paper 11 (PTAB Mar. 20, 2020) (precedential) (“Fintiv”),
`
`the Board discussed potential applications of NHK Spring Co., Ltd. v. Intri-
`
`Plex Techs., Inc., IPR2018-00752, Paper 8 (PTAB Sept. 12, 2018)
`
`11
`
`
`
`Case 5:19-cv-00036-RWS Document 485-6 Filed 08/05/20 Page 13 of 35 PageID #: 26506
`
`IPR2020-00204
`Patent 6,928,306 B2
`
`(precedential) (“NHK”), as well as a number of other cases dealing with
`
`discretionary denial under § 314(a). Fintiv identifies a non-exclusive list of
`
`factors parties may consider addressing, particularly where there is a related,
`
`parallel district court action and whether such action provides any basis for
`
`discretionary denial. Fintiv at 5–16. Those factors include:
`
`1. whether the court granted a stay or evidence exists that one
`may be granted if a proceeding is instituted;
`
`2. proximity of the court’s trial date to the Board’s projected
`statutory deadline for a final written decision;
`
`3. investment in the parallel proceeding by the court and the
`parties;
`
`4. overlap between issues raised in the petition and in the parallel
`proceeding;
`
`5. whether the petitioner and the defendant in the parallel
`proceeding are the same party; and
`
`6. other circumstances that impact the Board’s exercise of
`discretion, including the merits.
`
`Id. at 5–6. We authorized the parties to address these factors in the Reply
`
`and Sur-reply. Paper 7.
`
`We now consider these factors to determine whether we should
`
`exercise discretion to deny institution under 35 U.S.C. § 314(a). In
`
`evaluating the factors, we take a holistic view of whether efficiency and
`
`integrity of the patent system are best served by denying or instituting
`
`review. Fintiv at 6.

`Although Petitioner moved for a stay in the underlying litigation (see
`
`Pet. Reply 6; Ex. 1045), the court recently denied Petitioner’s motion.
`
`PO Sur-reply 2–3. We have entered the court’s order denying Petitioner’s

`
`Case 5:19-cv-00036-RWS Document 485-6 Filed 08/05/20 Page 14 of 35 PageID #: 26507
`
`IPR2020-00204
`Patent 6,928,306 B2
`
`motion into the record as Exhibit 3001. Notably, the court denied the
`
`motion without prejudice and stated that it could not say, in the event that we
`
`instituted this IPR, whether “the late stage [of proceedings] would
`
`necessarily outweigh the potential simplification of issues following
`
`institution decisions” in this and other inter partes review cases. Ex. 3001, 6
`
`(citing a prior case by the court in which a stay was granted three weeks
`
`before trial upon the institution of IPRs). In other words, the court signaled
`
`its willingness to entertain a renewed motion for stay from Petitioner if we
`
`were to issue decisions granting institution. Notwithstanding, the court
`
`stated that, were a renewed motion for stay requested, the late stage of
`
`proceedings “will certainly weigh against granting a stay.” Id. Given the
`
`court’s inclination to reconsider a motion for stay for the potential
`
`simplification of issues, but also considering the court’s comment about how
`
`the late stage of proceedings would affect its consideration of any such
`
`renewed motion, we view this factor as neutral.

`
`The Trial Date in the Underlying Litigation
`
`Trial in the underlying litigation is currently set for October 26, 2020.
`
`Pet. Reply 7; PO Sur-reply 1; Ex. 3001, 4. Nevertheless, Petitioner contends
`
`“[l]itigation will continue” after any Final Written Decision here. Pet.
`
`Reply 7. Petitioner notes that it filed a petition for writ of mandamus related
`
`to the court’s denial of Petitioner’s motion to transfer the underlying
`
`litigation. Id. Petitioner also notes the COVID-19 pandemic may affect the
`
`trial schedule. Id.
`
`Patent Owner argues that trial “will be complete nine months before a
`
`Final Written Decision issues” here and that a delay in the trial date is
`

`
`
`
`Case 5:19-cv-00036-RWS Document 485-6 Filed 08/05/20 Page 15 of 35 PageID #: 26508

`IPR2020-00204
`Patent 6,928,306 B2
`
`unlikely. PO Sur-reply 3. Patent Owner cites a standing order in the court
`
`of the underlying litigation “to keep cases moving” despite the COVID-19
`
`pandemic. Id. at 4 (quoting Ex. 2018). And, according to Patent Owner,
`
`even if the trial date were delayed by three months, the trial would still
`
`precede the Final Written Decision by five months. Id. at 4. Patent Owner
`
`additionally notes the U.S. Court of Appeals for the Federal Circuit recently
`
`denied Petitioner’s petition for writ of mandamus. Id. at 3–4 (citing In re
`
`Apple Inc., No. 2020-115, 2020 WL 2125340 (Fed. Cir. Apr. 22, 2020)).
`
`The trial in the underlying litigation is currently set to occur months
`
`before any Final Written Decision in this case will issue. Although we
`
`consider delays due to the COVID-19 pandemic to be a real possibility
`
`despite the court’s standing order, we agree with Patent Owner that even a
`
`delayed trial might precede a Final Written Decision. This factor favors the
`
`exercise of discretionary denial.
`
`
`
`3.
`
`Investment by the Court and the Parties in the Underlying
`Litigation
`
`Petitioner contends that, aside from claim construction proceedings,
`
`“the district court has not invested other substantive efforts and the litigation
`
`is not ‘advanced.’” Pet. Reply 8. Petitioner notes that summary judgment is
`
`still months away and fact discovery and depositions are ongoing. Id.
`
`According to Petitioner, the court is not likely to analyze invalidity until
`
`trial. Id.
`
`As evidence of the court’s investment in the underlying litigation,
`
`Patent Owner highlights the court’s claim construction hearing and order
`
`and its rulings on Petitioner’s motion to dismiss and motion to transfer. PO
`
`Sur-reply 5 (citing Exs. 1048, 2012–2014). Patent Owner also notes that
`
`14
`
`
`
`Case 5:19-cv-00036-RWS Document 485-6 Filed 08/05/20 Page 16 of 35 PageID #: 26509
`
`IPR2020-00204
`Patent 6,928,306 B2
`
`fact discovery has closed and that expert discovery is underway and closes
`
`June 25, 2020. Id. at 6 (citing, inter alia, Ex. 2015).
`
`At least some of the work underway or already completed in the
`
`underlying litigation likely has relevance to issues in the Petition, including
`
`claim construction and expert discovery. Nevertheless, the present record
`
`does not show how the court’s rulings on the motion to dismiss or the
`
`motion to transfer bear on the patentability issues presented here.
`
`Considering that some of the investment by the court and the parties in the
`
`underlying litigation may be relevant to issues in this case, we find this
`
`factor favors the exercise of discretionary denial.
`
`
`
`4.
`
`Overlap of the Issues
`
`Petitioner contends there is little overlap between the issues in this
`
`case and those in the underlying litigation. Pet. Reply 9–10. Although
`
`Petitioner acknowledges that the primary reference in this case,
`
`Van der Salm, is also asserted as a primary reference in the underlying
`
`litigation, Petitioner emphasizes that it has stipulated to withdraw
`
`Van der Salm from the underlying litigation if we were to institute inter
`
`partes review in this case. Pet. Reply 9 (citing Ex. 1047, 3 n.4). Petitioner
`
`contends that its approach “ensures that overlapping resources are not
`
`expended in the district court and in the IPR.” Id. Petitioner further notes
`
`that “Borland ’347,” a primary reference in the underlying litigation, is not
`
`asserted here. Id. at 10. Finally, Petitioner notes that only claims 12 and 15
`
`are challenged in the underlying litigation, which is a subset of the seven
`
`claims challenged here. Id. at 10.
`
`15
`
`
`
`Case 5:19-cv-00036-RWS Document 485-6 Filed 08/05/20 Page 17 of 35 PageID #: 26510
`
`IPR2020-00204
`Patent 6,928,306 B2
`
`Patent Owner argues “[t]he issues in this proceeding are substantially
`
`the same as in the District Court Action.” PO Sur-reply 7. Patent Owner
`
`disputes that Petitioner’s contingent offer to withdraw Van der Salm from
`
`the underlying litigation is a tenable solution to the problem of overlap
`
`between the two cases. Id. Patent Owner argues that both parties “are
`
`expending resources in the District Court Action on expert reports
`
`addressing invalidity issues and will have to continue to do so even if the
`
`Board institutes.” Id. Patent Owner also notes the common application of
`
`Miura in both cases. Id. at 8. Patent Owner additionally notes it was
`
`required to narrow the set of asserted claims in the underlying litigation, so
`
`Patent Owner argues Petitioner cannot “avoid denial simply by challenging
`
`extraneous unasserted claims that that raise the same invalidity issues as the
`
`asserted ones.” Id.
`
`Although Van der Salm is currently a primary reference both here and
`
`in the underlying litigation, Petitioner has proposed to withdraw
`
`Van der Salm in the underlying litigation if we were to institute inter partes
`
`review. See Ex. 1047, 3 n.4. Petitioner’s proposal to withdraw
`
`Van der Salm alleviates, to some degree, concerns of duplicative efforts
`
`between the district court and the Board, and further minimizes the potential
`
`for conflicting decisions. See Sand Revolution II, LLC v. Cont’l Intermodel
`
`Grp.–Trucking LLC, IPR2019-01393, Paper 24 at 11–12 (PTAB June 16,
`
`2020); see also Fintiv at 12 (analyzing NHK to determine there were
`
`“concerns of inefficiency and the possibility of conflicting decisions.”).
`
`This withdrawal would also streamline the court’s consideration of invalidity
`
`issues in the underlying litigation and create a significant distinction
`
`between this case and the underlying litigation. Nevertheless, the lack of
`
`16
`
`
`
`Case 5:19-cv-00036-RWS Document 485-6 Filed 08/05/20 Page 18 of 35 PageID #: 26511
`
`IPR2020-00204
`Patent 6,928,306 B2
`
`overlap is diminished somewhat by the fact that Van der Salm has been a
`
`subject of expert discovery in the underlying litigation. See PO Sur-reply 7;
`
`see also supra § II.D.3 (noting the court and parties’ investment in the
`
`underlying litigation). We also have considered Miura’s overlapping role as
`
`a secondary reference in both cases, but determine that Petitioner’s
`
`challenges here based on Van der Salm and Huang are necessarily different
`
`than those based on Borland ’347 in the underlying litigation. Finally,
`
`claims 2, 5, 7, 13, and 14 are being challenged here, but not in the
`
`underlying litigation, which favors institution. On balance, we view this
`
`factor as weighing against exercising discretion to deny.
`
`
`
`5. Whether Petitioner is Unrelated to the Defendant in the
`Underlying Litigation
`
`“If a petitioner is unrelated to a defendant in an earlier court
`
`proceeding, the Board has weighed this fact against exercising discretion.”
`
`Fintiv at 13–14. Both parties acknowledge that Petitioner here is the
`
`defendant in the underlying litigation. Pet. Reply 10; PO Sur-reply 10.
`
`Thus, this factor does not weigh against exercising discretionary denial.
`
`
`
`6.
`
`Other Considerations
`
`The final Fintiv factor is a catch-all that takes into account any other
`
`relevant circumstances. The decision whether to exercise discretion to deny
`
`institution under § 314(a) is based on “a balanced assessment of all relevant
`
`circumstances in the case, including the merits.” Patent Trial and Appeal
`
`Board Consolidated Trial Practice Guide at 58 (Nov. 2019) (“Consolidated
`
`Trial Practice Guide”), available at https://www.uspto.gov/sites/default/

`
`IPR2020-00204
`Patent 6,928,306 B2
`
`arguments in the Petition and Patent Owner’s arguments in the Preliminary
`
`Response, as discussed below, we determine Petitioner has established a
`
`reasonable likelihood that Petitioner would prevail with respect to the
`
`challenged claims. As discussed below, Petitioner cites the primary
`
`reference, Van der Salm, for teaching a telecommunications terminal with
`
`ring generator means that can form a ring signal with a calling party identity
`
`sound, a sound associated with a group identity representation, and/or a call
`
`representation sound. See infra § II.E.3. Based on the present record,
`
`Van der Salm alone appears to teach most, if not all, limitations of the
`
`challenged independent claims. Accordingly, the particularly strong merits
`
`of the challenges presented in the Petition favor institution.
`
`Patent Owner argues that Petitioner unreasonably delayed in filing the
`
`Petition. PO Sur-reply 1–2, 8–10. The district court in the underlying
`
`litigation also stated that Petitioner “has not sufficiently explained its delay
`
`in filing the petitions . . . nine months after [Patent Owner] filed suit and six
`
`months after [Patent Owner] served its initial infringement contentions.”
`
`Ex. 3001, 4–5.
`
`Petitioner notes that the underlying litigation initially involved
`
`10 different patents and “132 possibly-asserted claims”; Petitioner argues
`
`that it needed time to locate relevant prior art and prepare petitions for inter
`
`partes review. Pet. Reply 7–8. Petitioner’s explanation is consistent with
`
`the AIA’s legislative history as to the one-year statutory bar under § 315(b).
`
`See 157 Cong. Rec. S5429 (daily ed. Sept. 8, 2011) (statement of Senator
`
`Kyl) (“High-technology companies, in particular, have noted that they are
`
`often sued by defendants asserting multiple patents with large numbers of
`
`vague claims, making it difficult to determine in the first few months of the

`understand the patent claims that are relevant to the litigation.”). We also
`
`note that Patent Owner made its Preliminary Election of Asserted Claims in
`
`the underlying litigation on No
