`
`INTRODUCTION
`
`IngenioShare alleges Epic Games infringes sixty-nine claims from four patents relating to
`
`systems, methods, and apparatuses for managing electronic communications. The asserted claims
`
`contain a jumble of technical jargon mixed with confusing terms. It is clear from IngenioShare’s
`
`infringement contentions and Epic Games’ invalidity contentions that a dispute exists about the
`
`meaning (to the extent one is discernible) of certain claim terms. IngenioShare tries to side-step
`
`claim construction by advocating “plain and ordinary meaning” for all the terms at issue, without
`
`any elucidation of what it believes that meaning is. But where, as here, the parties have a dispute,
`
`a “plain and ordinary meaning” construction should be rejected because it would effectively submit
`
`legal questions to the jury. The court, not the jury, must resolve these disputes.
`
`The Court should adopt Epic Games’ proposals, finding terms that are insolubly ambiguous
`
`to be indefinite, and applying the proposed constructions for the remaining terms, which
`
`constructions are grounded in the claim language, patent specifications, and extrinsic evidence.
`
`II.
`
`OVERVIEW OF THE PATENTS
`
`IngenioShare alleges Epic Games infringes U.S. Patent Nos. 8,744,407 (the “’407 Patent”);
`
`10,142,810 (the “’810 Patent”); 10,492,038 (the “’038 Patent”); 10,708,727 (the “’727 Patent”)
`
`(the “Asserted Patents”). The claims in the Asserted Patents overlap significantly and share largely
`
`identical specifications and figures. See generally, ’407 Patent; ’810 Patent; ’038 Patent; ’727
`
`Patent (attached as Exs. J–M). Each Asserted Patent derives from the same provisional application
`
`(U.S. Provisional Patent Application No. 60/689,686) and has the same priority date of April 27,
`
`2005.
`
`The Asserted Patents’ claims are all directed
`
`to managing person-to-person
`
`communications from multiple devices such as “desk phones, fax, cell phones, electronic mails,
`

`Patent Owner Ex. 2004, p. 5

`
`
`
`Case 6:21-cv-00663-ADA Document 30 Filed 01/10/22 Page 6 of 34
`
`
`
`and instant messages.” See ’407 Patent, 1:34–37; ’810 Patent, 1:50–53; ’038 Patent, 1:59–62; ’727
`
`Patent, 1:64–67. Specifically, the Asserted Patents disclose methods and systems of managing
`
`communications by transmitting them via a “network-based portal,” and allowing the intended
`
`recipients of communications to pick and choose which communications they actually receive.
`
`See ’407 Patent, 3:19–21; ’810 Patent, 1:67–2:13; ’038 Patent, 4:10–14; ’727 Patent, 4:1–5. To
`
`this end, the Asserted Patents describe a “person” (sometimes referred to as a “first user”)
`
`attempting to send a message to a “user” (sometimes referred to as a “second user”). See, e.g.,
`
`’407 Patent, 1:49–50 (“A person tries to electronically convey a message to the user.”); ’810
`
`Patent, 2:24–25, cls. 1, 11, 19; ’038 Patent, 2:32–33, cls. 7, 38, 46; ’727 Patent, Abstract, 2:14–15,
`
`cl. 1. The first user is provided with a number of communication options (sometimes referred to
`
`as “communication modes” or “modes of communication”) including text messaging and voice
`
`communications. See, e.g., ’407 Patent, cls. 53, 56; ’810 Patent, cls. 1, 11, 19; ’038 Patent, cls. 7,
`
`38, 46; ’727 Patent, cl. 1.
`
`The Asserted Patents’ allegedly inventive aspect relates to communication features beyond
`
`the first user’s ability to send a message to a second user. For example, a second user can
`
`automatically block communications from a first user (see ’407 Patent, 3:54–57; ’810 Patent, 4:49–
`
`52; ’038 Patent, 4:58–61; ’727 Patent, 4:39–42), and/or respond with a predetermined message.
`
`See ’810 Patent, Figs. 8, 9 (outlining predetermined audio and text messages to respond to
`
`incoming communications); ’038 Patent, Figs. 8, 9 (same); ’727 Patent, Figs. 8, 9 (same).
`
`Additionally, the second user can set a status indicating whether he or she is busy, resting, or
`
`available to communicate with a first user. See ’810 Patent, 6:8–9, Fig. 4; ’038 Patent, 6:19–20,
`
`Fig. 4; ’727 Patent, 5:66–67, Fig. 4. Further, an indication about a message may provide
`
`information about the message, such as the “voice, tone, pace, accent, and/or mood” of the
`
`
`

`
`Case 6:21-cv-00663-ADA Document 30 Filed 01/10/22 Page 7 of 34
`
`
`
`message. See, e.g., ’810 Patent, 18:27–34; ’038 Patent, 18:37–41; ’727 Patent, 18:20–27.
`
`Moreover, even when the second user receives a message from the first user, each user’s contact
`
`information (e.g., phone number or email address) is not provided to the other user by virtue of the
`
`message being received. See ’407 Patent, 2:8–15, 4:27–37, cl. 53; ’810 Patent, 2:50–57, 5:22–32,
`
`cls. 1, 11, 19; ’038 Patent, 2:58–65, 5:32–43, cls. 7, 38, 46; ’727 Patent, 2:40–47, 5:12–23, cl. 1.
`
`In short, the alleged invention claimed by the Asserted Patents allows a first user to attempt sending
`
`a message to a second user, while providing other communications features.
`
`III. RELEVANT LEGAL STANDARDS
`
`“An infringement analysis entails two steps. The first step is determining the meaning and
`
`scope of the patent claims asserted to be infringed. The second step is comparing the properly
`
`construed claims to the device accused of infringing.” Markman v. Westview Instruments, Inc., 52
`
`F.3d 967, 976 (Fed. Cir. 1995) (citation omitted). The first step, claim construction, is a question
`
`of law that relies primarily on intrinsic evidence, including the claim language, the specification,
`
`and the prosecution history, to determine the scope of disputed claims. See Phillips v. AWH Corp.,
`
`415 F.3d 1303, 1321 (Fed. Cir. 2005).
`
`There are several instances where a term must be construed beyond its plain and ordinary
`
`meaning. Construction is necessary “when a term has more than one ‘ordinary’ meaning or when
`
`reliance on a term’s ‘ordinary’ meaning does not resolve the parties’ dispute,” in which case the
`
`plain and ordinary meaning “may be inadequate.” O2 Micro Int’l Ltd. v. Beyond Innovation Tech.
`
`Co., 521 F.3d 1351, 1361 (Fed. Cir. 2008). Indeed, because claim construction “is a question of
`
`law that must be decided by the court,” where the parties dispute the scope of a claim term,
`
`adopting a “plain and ordinary meaning” construction would improperly “submit[] a legal question
`
`to the jury.” See id. at 1360. Construction is also necessary where the patentee, “acting as his or
`
`
`
`
`3
`
`Patent Owner Ex. 2004, p. 7
`IPR2022-00202
`
`
`
`Case 6:21-cv-00663-ADA Document 30 Filed 01/10/22 Page 8 of 34
`
`
`
`her own lexicographer, has clearly set forth an explicit definition of the term different from its
`
`ordinary meaning.” Phillips, 415 F.3d at 1319. A patentee may explicitly define a term using by
`
`using a parenthetical phrase. See Abbott Labs. v. Novopharm Ltd., 323 F.3d 1324, 1327, 1330
`
`(Fed. Cir. 2003) (construing “solid surfactant” in accordance with ensuing parenthetical phrase).
`
`Similarly, a claim term should be construed where “it is apparent from the patent and prosecution
`
`history that the inventor used the term with a different meaning” from its plain and ordinary
`
`meaning. Hoechst Celanese Corp. v. BP Chems. Ltd., 78 F.3d 1575, 1578 (Fed. Cir. 1996).
`
`Construction is likewise required where a term has no plain and ordinary meaning, in which case
`
`the term “cannot be construed broader than the disclosure in the specification.” Indacon, Inc. v.
`
`Facebook, Inc., 824 F.3d 1352, 1357 (Fed. Cir. 2016).
`
`In cases where construction is required, “the patent’s specification and prosecution history
`
`must be consulted[.]” Phillips, 415 F.3d at 1319. “[T]he specification is always highly relevant
`
`to the claim construction analysis. Usually it is dispositive; it is the single best guide to the
`
`meaning of a disputed term.” Id. at 1315 (internal quotation marks omitted). Indeed, “[t]he
`
`construction that stays true to the claim language and most naturally aligns with the patent’s
`
`description of the invention will be, in the end, the correct construction.” Id. at 1316 (citation
`
`omitted). “The inventor’s words that are used to describe the invention—the inventor’s
`
`lexicography—must be understood and interpreted by the court as they would be understood and
`
`interpreted by a person in that field of technology.” Id. at 1477. Additionally, “when a patentee
`
`uses a claim term throughout the entire patent specification, in a manner consistent with only a
`
`single meaning, he has defined that term ‘by implication.’” Bell Atl. Network Servs., Inc. v. Covad
`
`Commc’ns Grp., Inc., 262 F.3d 1258, 1271 (Fed. Cir. 2001) (citation omitted); see id. at 1273

`
`
`
`Case 6:21-cv-00663-ADA Document 30 Filed 01/10/22 Page 9 of 34
`
`
`
`(“[T]he patentees defined the term ‘mode’ by implication, through the term’s consistent use
`
`throughout the [] specification.”).
`
`When construing claim terms, “claims are interpreted with an eye toward giving effect to
`
`all terms in the claim.” Bicon, Inc. v. Straumann Co., 441 F.3d 945, 950 (Fed. Cir. 2006). To read
`
`claim language as superfluous, as opposed to limiting, “would render the scope of the patent
`
`ambiguous, leaving examiners and the public to guess about which claim language the drafter
`
`deems necessary to his claimed invention . . . .” Id. Similarly, as this Court has recognized,
`
`“[w]hen an applicant uses different terms in a claim it is permissible to infer that he intended his
`
`choice of different terms to reflect a differentiation in the meaning of those terms.” Digit. Retail
`
`Apps, Inc. v. H-E-B, LP, No. 6-19-CV-00167-ADA, 2020 WL 376664, at *8 (W.D. Tex. Jan. 23,
`
`2020) (“Clearly, the terms ‘verifying’ and ‘spot-checking’ are distinct terms that are not
`
`interchangeable.”); see also Ethicon Endo-Surgery, Inc. v. U.S. Surgical Corp., 93 F.3d 1572, 1579
`
`(Fed. Cir. 1996) (“If the terms ‘pusher assembly’ and ‘pusher bar’ described a single element, one
`
`would expect the claim to consistently refer to this element as either a “pusher bar” or a “pusher
`
`assembly,” but not both[.]”).
`
`“[A] patent is invalid for indefiniteness if its claims, read in light of the specification
`
`delineating the patent, and the prosecution history, fail to inform, with reasonable certainty, those
`
`skilled in the art about the scope of the invention.” Nautilus, Inc. v. Biosig Instruments, Inc., 572
`
`U.S. 898, 901 (2014). “Even if a claim term’s definition can be reduced to words, the claim is still
`
`indefinite if a person of ordinary skill in the art cannot translate the definition into meaningfully
`
`precise claim scope.” Interval Licensing LLC v. AOL, Inc., 766 F.3d 1364, 1371 (Fed. Cir. 2014).

`
`IV. CONSTRUCTION OF THE DISPUTED TERMS
`
`A.
`
`Terms Appearing First in U.S. Pat. No. 8,744,4071

`Claim Term
`
`Epic Games’ Proposed
`Construction
`
`IngenioShare’s Proposed
`Construction
`
`“process”
`
`Indefinite
`
`Plain and ordinary meaning
`
`Construction of the term “process” is necessary because a POSITA would not have
`
`understood the scope of the claimed “process” with reasonable certainty. See Nautilus, 572 U.S.
`
`at 901.
`
`First, the independent claims of the ’407 Patent fail to define “process” in a way that would
`
`help a POSITA discern “meaningfully precise claim scope.” See Interval Licensing, 766 F.3d at
`
`1371 (holding that a term is indefinite if a POSITA would not have understood the term with
`
`meaningfully precise claim scope). For example, claim 53 recites “[a] server comprising: at least
`
`one computing device . . . wherein at least one computing device is configured to . . . set a process
`
`for the message using one or more rules.” ’407 Patent, cl. 53; see also id., cls. 1, 8, 24, 39 (similar
`
`disclosures). This recitation would not have helped a POSITA understand the scope of the term
`
`“process,” as it provides no information regarding the steps of the process. The independent claims
`
`merely state that the process is “set . . . using one or more rules,” is “for the message,” and may
`
`
`1 Epic Games presents terms to be construed in the order provided in the Court’s Nov. 17, 2021
`Standing Order.
`
`2 The listed claims include independent and dependent claims that expressly recite the disputed
`claim term. Epic Games’ proposed constructions additionally apply to all claims (regardless of
`whether they recite the disputed term) that depend on such claims. Epic Games’ proposed
`constructions apply to each element of the asserted claims, independent or dependent, using the
`same or similar language as the terms and phrases proposed for construction.
`
`
`
`
`6
`
`Patent Owner Ex. 2004, p. 10
`IPR2022-00202
`
`
`
`Case 6:21-cv-00663-ADA Document 30 Filed 01/10/22 Page 11 of 34
`
`
`
`optionally include “transmitting the message.” See, e.g., id., cl. 53 (“wherein even if the process
`
`includes transmitting the message to the second device . . . .”). These recitations do nothing to
`
`explain what the process is, much less what it means for a process to be “for the message” or for
`
`one or more (unidentified) rules to be used to “set” the process. A POSITA reading these claims
`
`would not understand, for instance, what the steps of the process are, what the result of the process
`
`is, or what the “one or more rules” are. At best, these claims indicate that either the process or the
`
`rules are “based on at least a status associated with the user and an access priority associated with
`
`the person.” E.g., id. (grammatically ambiguous). But the claims do not describe how the “status”
`
`and “access priority” affect the process. Thus, a POSITA would have had no reasonable certainty
`
`as to the scope of the term “process” in light of the independent claims. Wicker Decl. ¶ 32.
`
`Second, the dependent claims that refer to a “process” do not clarify the scope of this term.
`
`Several of the dependent claims recite the same or similar language from the independent claims.
`
`See ’407 Patent, cls. 7, 23, 38. The other dependent claims that include the term “process” merely
`
`add limitations to the claimed process without providing guidance on what that term (as used by
`
`the independent claims) entails. The dependent claims indicate that the process may, for example:
`
`• Depend on an urgency level of the message. See id., cls. 3, 9, 25, 40, 55.
`
`• Depend on a mode of communication of the message. See id., cls. 10, 26, 56.
`
`• Cause an additional message to be sent. See id., cls. 15–17, 31, 34, 36, 45, 46, 48.
`
`• Set an appointment between the first and second user. See id., cls. 22, 37, 51.
`
`Importantly, none of these examples explains the steps or rules of the independently claimed
`
`“process.” Rather, they merely indicate that “process” as used in the independent claims does not
`
`encompass the above examples. See Phillips, 415 F.3d at 1314–15 (“[T]he presence of a dependent
`
`
`
`
`7
`
`Patent Owner Ex. 2004, p. 11
`IPR2022-00202
`
`
`
`Case 6:21-cv-00663-ADA Document 30 Filed 01/10/22 Page 12 of 34
`
`
`
`claim that adds a particular limitation gives rise to a presumption that the limitation in question is
`
`not present in the independent claim.”); Wicker Decl. ¶¶ 33–34.
`
`Dependent claim 19 further illustrates this point. This claim requires that the process
`
`“determin[es] whether the message should be delivered to the user based on at least one attribute
`
`of the message,” and either “deliver[s] the message” or “declin[es] to deliver the message.” ’407
`
`Patent, cl. 19; see also id., cls. 30, 44. As noted above, this dependent claim indicates that the
`
`scope of the independently claimed “process” does not include making the determination described
`
`in claim 19. See Phillips, 415 F.3d at 1314–15. But it also does not explain how the process of
`
`claim 19 makes this determination. For instance, the claim does not describe what rules (if any)
`
`are consulted, what the “at least one attribute of the message” is, how the “attribute” relates to the
`
`rules (if any), and how the “attribute” affects the determination. See id. This claim (and the other
`
`dependent claims) therefore provide no guidance regarding the scope of the independently claimed
`
`“process.” Wicker Decl. ¶ 34.
`
`Third, the specification provides no assistance. The summary of the invention simply
`
`parrots the unhelpful claim language: “[i]n one embodiment . . . a process is set to manage the
`
`message using one or more rules[.]” ’407 Patent, 1:50–56. It does not provide any clarification
`
`of the process’s operation, stating only that the “process can depend on the mode of communication
`
`of the message” and that the “process allows the user to receive the message.” Id., 1:64–65, 2:8–
`
`9. But other than these cursory statements, the specification, like the claim language, does not
`
`clarify what the steps of the process are, what the result of the process is, or what the “one or more
`
`rules” are. See generally id.; Interval Licensing, 766 F.3d at 1371 (holding that even if a term can
`
`be defined, it is indefinite if a POSITA would not have understood the term with meaningfully
`
`precise claim scope).

`
`
`
`Fourth, dictionary definitions confirm that a POSITA would have needed to understand
`
`the steps of a process to understand its scope. In the computing context, dictionaries indicate that
`
`a “process” comprises several steps. See Ex. A (Collins English Dictionary (2005)) at 1292
`
`(“computing to perform mathematical and logical operations on (data) according to programmed
`
`instructions in order to obtain the required information); Ex. C (Microsoft Computer Dictionary
`
`(2002)) at 423 (“[a] program or part of a program; a coherent sequence of steps undertaken by a
`
`program.”); Ex. D (Newton’s Telecom Dictionary (2005)) at 672 (“[a]n operating system object
`
`that consists of an executable program, a set of virtual memory addresses, and one or more
`
`threads. When a program runs, a process is created.”). Thus, a POSITA would have needed to
`
`understand a process’s series of steps in order understand the scope of the process. See Wicker
`
`Decl. ¶ 36.
`
`Because the term “process” has undefined claim scope, the term is indefinite. See Nautilus,
`
`572 U.S. at 910.

`
`Construction of the term “availability” is necessary because the patentee used the specific
`

`
`
`Phillips, 415 F.3d at 1319; Hoechst Celanese, 78 F.3d at 1578. This is in contrast to a user’s
`
`online/offline presence. In the field of network-based communications, a user’s “presence” refers
`
`to whether his or her electronic device is switched on and connected to a network. See Wicker
`
`Decl. ¶ 40. For example, if a user turns her electronic device on and logs in to a chat platform, but
`
`then sets her status to “Do Not Disturb” (thereby preventing others from reaching her), she is
`
`“present” on the network but not “available” to receive messages. See id. Based on its
`
`infringement contentions, however, IngenioShare appears to contend that a user’s “availability” is
`
`the same as a user’s presence. See, e.g., Ex. G3 (Plaintiff’s Preliminary Infringement Contentions
`
`(excerpted)) at 11 (citing only online/offline status in support of “availability” with respect to the
`
`’727 Patent), 18–19, 22–27 (same with respect to the ’038 Patent), 31–34 (same with respect to
`
`the ’810 Patent), 37–40 (same with respect to the ’407 Patent). Because the parties have a dispute,
`
`IngenioShare’s “plain and ordinary meaning” proposal should be rejected and the Court should
`
`construe the term as “willingness to communicate,” which is rooted in the specification and
`
`supported by extrinsic evidence.
`
`First, the Asserted Patents’ specifications make clear that, when they use the term
`
`“availability,” they are referring to the second user’s willingness to communicate, and not whether
`
`the second user is online or offline. Specifically, the Asserted Patents indicate in Figure 4
`
`(common to all four patents) that “Available” is a user-defined status, which can be selected from
`
`other statuses such as “Important meeting,” “Ordinary meeting,” “Sleeping,” “Resting,” and “User
`
`defined.” See ’407 Patent, 5:10–11 (“The user can define a number of status[es], as shown in
`
`FIG. 4.”), Fig. 4; ’810 Patent, 6:8–9, Fig. 4; ’038 Patent, 6:19–20, Fig. 4; ’727 Patent, 5:66–67,
`
`
`3 Because IngenioShare used non-consecutive page numbering in its Preliminary Infringement
`Contentions, Epic Games’ citations to these excerpted contentions are to the page number of the
`PDF.

`
`
`
`Fig. 4. These availability indicators are set by the second user to allow receipt of certain
`
`communications and to filter out unwanted communications. See ’407 Patent, 3:31–33 (describing
`
`users using these availability indicators to “determine who can reach them at what conditions”);
`
`’810 Patent, 3:47–58, 4:25–27; ’038 Patent, 3:65–67, 4:33–36; ’727 Patent, 3:46–48, 4:14–17. For
`
`example, “if the user is having his yearly review meeting with his boss,” he could change his status
`
`to “Important meeting,” which would allow him to “avoid [a] call from his grandchild[.]” See
`
`’407 Patent, Fig. 4, 2:61–63; ’810 Patent, Fig. 4, 3:53–55; ’038 Patent, Fig. 4, 3:62–64; ’727 Patent,
`
`Fig. 4, 3:43–45. As used consistently throughout the Asserted Patents’ specifications, a second
`
`user’s status of “Available” indicates his/her willingness to receive certain communications. See
`
`Bell Atl., 262 F.3d at 1271 (“[W]hen a patentee uses a claim term throughout the entire patent
`
`specification, in a manner consistent with only a single meaning, he has defined that term ‘by
`
`implication.’”); In re Abbott Diabetes Care, Inc., 696 F.3d 1142, 1149–50 (Fed Cir. 2012)
`
`(construing term in view of specification’s usage where specification “repeatedly, consistently,
`
`and exclusively” described the term in a certain way).
`
`Second, a POSITA would have understood from contemporaneous inventors in the field
`
`of electronic communications that a second user’s “availability” refers to the second user’s
`
`willingness to communicate. See Wicker Decl. ¶ 43. This is explained in U.S. Patent Application
`
`No. 2002/0116461 [hereinafter “Diacakis”], which teaches an Internet-based communications
`
`system. There, the term “availability” is expressly defined as “the willingness of an individual
`
`who is present on one or more communications networks to be reached by one or more persons.”
`
`Ex. H (Diacakis), [0027]. By contrast, Diacakis defines the term “presence” as “the ability of an
`
`individual to access a particular communications network.” Id. at [0026]. Thus, “if a person is
`
`near a landline or wireless telephone and has the intention or willingness to answer the phone

`
`
`
`when a particular person calls, the person is not only present but available on the telephone
`
`network.” Id. at [0027].
`
`A determination that “availability” has its “plain and ordinary” meaning would be
`
`inadequate to resolve the parties’ dispute (see O2 Micro, 521 F.3d at 1361), and the Court should
`
`construe “availability” as “willingness to communicate.”

`
`Plain and ordinary
`meaning
`
`Construction of the terms “text messaging” and “text message” is necessary because the
`
`patentee did not use the term in a broad sense to refer to any and every kind of text-based
`
`communication. See Phillips, 415 F.3d at 1319; Hoechst Celanese, 78 F.3d at 1578. The patentee
`
`used the broader term “text communication” in other Asserted Patents, and used “text messaging”
`
`in dependent claims to narrow the scope of text communications. In addition, the patentee
`
`consistently used the term “text messaging” to refer to SMS (“Short Message Service”) messaging,
`
`which is a standardized way mobile phones send and receive text communications over a wireless
`
`network. Wicker Decl. ¶¶ 23–24, 46. Thus, the term “text messaging” should be given the
`
`construction “SMS messaging.”

`
`
`
`First, based on the claim language itself, the term “text messaging” cannot refer to every
`
`type of “text communication.” In fact, the ’038 and ’727 Patents use the term “text
`
`communication” broadly to refer to text-based communications, of which text (SMS) messaging
`
`is one example. For instance, the ’727 Patent recites “text communication” in independent claim 1
`
`and narrows this scope to “text message” in dependent claim 10. See ’727 Patent, cls. 1, 10.
`
`Similarly, the ’038 Patent recites “text communication” in independent claims 7, 38, and 46 and
`
`narrows this scope to “text message” in dependent claims 13, 14, 17, 20, 25–27, 35, 41, and 68–
`
`70. ’038 Patent, cls. 7, 13, 14, 17, 20, 25–27, 35, 38, 41, 46, 68–70. An applicant’s choice to use
`
