`
`INTRODUCTION
`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`Patent Owner’s proposed amendments lack written description support, are
`
`indefinite, impermissibly broaden the scope of the claims, and are invalid based on
`
`the prior art raised in the Petition. Patent Owner’s Motion to Amend should
`
`therefore be denied.
`
`The ’933 patent relates to displaying network names on mobile phones.
`
`Specifically, the patent teaches the use of an “HPLMN list,” which includes multiple
`
`“home” networks such that the same home network name is displayed when the
`
`phone is connected to any of those networks. According to the ’933 patent, using
`
`an HPLMN list in this way reduces confusion for a subscriber, who may see a
`
`network name displayed that is different from her home network and assume that
`
`she is incurring roaming charges, when in fact she is not. Throughout the
`
`specification, the HPLMN list is a critical and mandatory element of the invention,
`
`and it is stored on either the SIM card or in the mobile device’s memory so it can be
`
`accessed for use with the above name display procedures.
`
`Patent Owner’s proposed amendments turn the ’933 patent on its head. In the
`
`proposed amendments, the Patent Owner introduces a new concept totally alien and
`
`contradictory to the original disclosure: that the HPLMN list could be absent from
`
`the mobile device entirely—i.e., not on the SIM card or in memory. However, in
`
`such circumstances, the patented method is not performed at all. As a result, the
`
`
`
`1
`
`
`
`
`
`
`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`
`proposed amendments are plainly impermissible. Specifically, the substitute claims
`
`are unpatentable on the following bases:
`
`• Lack of Written Description. The proposed amendments lack written
`
`description support. The ’933 patent requires an HPLMN list to be stored in
`
`either the SIM or in memory; there is no support anywhere in the specification
`
`for a limitation that the HPLMN list is stored in neither. Nor is there support
`
`for a condition that the allegedly inventive home network name display
`
`methods not be performed at all if the HPLMN list is not found.
`
`• Indefiniteness. The substitute claims are dependent on method claim 1,
`
`which requires specific steps to be taken to display a home network name.
`
`The proposed dependent claims, however, instruct that these steps only be
`
`performed if a certain condition is met (i.e., the HPLMN list is in the SIM or
`
`memory). The substitute claims are therefore internally contradictory and
`
`indefinite because it is unclear to a POSITA whether the steps of claim 1 are
`
`ever performed.
`
`• Impermissible Broadening. By making certain limitations of claim 1
`
`optional, the substitute claims impermissibly broaden the scope of the claims.
`
`For example, while claim 1 is satisfied only if all steps are performed and a
`
`network name is displayed, the substitute claims can be satisfied without
`
`displaying a network name at all. For similar reasons, the proposed claims
`
`
`
`2
`
`
`
`
`
`
`
`
`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`violate Section 112 ¶ 4 because they do not “specify a further limitation” of
`
`the independent claim. To the contrary, the substitute claims remove
`
`limitations from the independent claim by making them conditional.
`
`• Obviousness. The substitute claims are no less obvious than the original
`
`claims. Indeed, the limitations added in the substitute claims are obvious
`
`under the same grounds raised in the Petition. For example, the idea of
`
`checking for a particular data structure (here, the HPLMN list) in a SIM card
`
`and memory is disclosed in McElwain, which is part of all grounds.
`
`Furthermore, it is facially obvious to implement steps requiring a data
`
`structure only when that structure is present.
`
`For these and the other reasons explained below, Patent Owner’s Motion to
`
`Amend should be denied.
`
`II.
`
`SUMMARY OF THE PROPOSED AMENDMENTS
`
`Proposed substitute claims 20 and 21 are dependent on independent method
`
`claim 1. At a high level, method claim 1 recites the steps of:
`
`• Scanning for MCC/MNC pairs;
`
`• Selecting and registering with a network associated with one of the
`
`MCC/MNC pairs;
`
`• Comparing the MCC/MNC pair of the selected network with home networks
`
`of an HPLMN list;
`
`
`
`3
`
`
`
`
`
`
`
`
`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`• If there is a match between the MCC/MNC pair of the selected network and
`
`an MCC/MNC pair in the HPLMN list, displaying the home network name;
`
`and
`
`• Otherwise displaying an alternate network name.
`
`As summarized by the Patent Owner, the proposed substitute claims each add
`
`three new limitations to claim 1:
`
`(1) the requirement that the mobile station runs a test to determine
`whether the HPLMN list, containing a plurality of home network MCC
`and MNC pairs, is stored in the Subscriber Identity Module (“SIM”), in
`the mobile station’s memory, or neither, (2) the condition that method
`of claim 1 is implemented if the HPLMN list is contained on the mobile
`station’s SIM or in its memory; and the additional requirement that
`(3) the aforementioned test is performed at explicitly noted times.
`
`PO Mot. at 4.1 Thus, with the substitute claims, a UE “only carr[ies] out the methods
`
`of claim 1 when a specific test for an HPLMN list returns a confirmation of the
`
`HPLMN list’s presence on the UE’s SIM card or in its memory.” Id. at 4‒5.
`
`
` 1 The analysis below refers to these as “limitation (1),” “limitation (2),” and
`
`“limitation (3),” respectively.

`
`
`III. THE PROPOSED AMENDMENTS LACK WRITTEN DESCRIPTION
`SUPPORT
`
`There is no written description in the specification of the ’933 patent for any
`
`of the three new limitations. Amendments “may not enlarge the scope of the claims
`
`of the patent or introduce new matter.” 35 U.S.C. § 316(d)(3). To satisfy this
`
`requirement, every proposed claim limitation must have written description support
`
`in the original specification. See Verify Smart Corp. v. Askeladden, L.L.C., 824 F.
`
`App’x 1015, 1023 (Fed. Cir. 2020) (affirming denial of motion to amend because
`
`proposed amendments lacked written description support). The written description
`
`requirement under 35 U.S.C. § 112 requires that the patent specification “reasonably
`
`conveys” possession of the claimed invention to persons of skill. Ariad Pharm., Inc.
`
`v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010). The Federal Circuit has
`
`emphasized that “[a] description that merely renders the invention obvious does not
`
`satisfy the [written description] requirement.” Id. at 1352.
`
`In its Motion, Patent Owner identifies four sentences from the application for
`
`the ’933 patent and two claims from the application as providing support for the
`
`amendments.2 See PO Mot. at 5‒10. None of these excerpts—nor anything else in
`
`
` 2 Patent Owner’s analysis of the alleged support for the substitute claims includes
`
`citations to European Appl. No. 03255483, which is incorporated by reference
`
`(Cont’d on next page)

`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`
`the specification of the ’933 patent—provides written description support for the
`
`proposed amendments.
`
`A. There Is No Support in the ’933 Patent for the “Or Neither”
`Element of Limitation (1)
`
`New limitation (1) introduces a new claim element: that the HPLMN list may
`
`be present in “neither” the SIM nor the mobile station memory. This concept is
`
`completely absent from the ’933 patent. Indeed, far from disclosing the idea that an
`
`HPLMN list may be entirely absent from a mobile station, the ’933 patent requires
`
`throughout the specification that the HPLMN list is stored in either the SIM or
`
`memory. See, e.g., Ex. 1001 at 2:60‒62, 3:46‒49, 12:30‒33, 12:41‒46, 13:18‒25,
`
`14:22‒26.
`
`
`into the ’933 patent. See PO Mot. at 5‒6. The citations to this application should
`
`be ignored. Pursuant to 37 C.F.R. § 1.57, “essential material”—which is defined
`
`as material “necessary to . . . [p]rovide a written description of the claimed
`
`invention”—may only be incorporated by reference “by way of an incorporation
`
`by reference to a U.S. patent or U.S. patent application publication.” In any
`
`event, the substance of the European application is the same as the U.S.
`
`application. Thus, even considering the language in the European application,
`
`the proposed substitute claims lack written description support.

`Motion to Amend in IPR2020-01157
`
`The specification excerpts alleged by Patent Owner to support the “or neither”
`
`limitation do not do so. See PO Mot. at 5‒6. The excerpts identified by Patent
`
`Owner identify only these two possibilities for the HPLMN list: that it is stored in
`
`the SIM or in the mobile station memory. See, e.g., Ex. 1002, 25 (“In a slight
`
`variation of the method of Fig. 7, the mobile station utilizes a multiple home network
`
`list on the SIM if it is stored on the SIM, but if such a list is not stored on the SIM,
`
`the mobile station utilizes a multiple home network list stored in its own memory.”);
`
`id. (“In one implementation, compatibility is provided between previous, current,
`
`and future versions mobile stations and SIMS by providing a test to identify the
`
`availability of such a list on the SIM and a similar backup list on the mobile
`
`station.”). Claims 7 and 14 of the original application similarly recite a method of
`
`using MCC/MNC pairs “stored on the SIM” and “otherwise, using the plurality of
`
`home network MCC and MNC pairs stored in the memory of the mobile station.”
`
`Id. at 29‒30. These excerpts unambiguously require the HPLMN list to be either in
`
`the SIM or memory; they exclude the possibility that it may be absent from both.
`
`The remainder of the specification is equally clear on this point: the HPLMN
`
`list may be in the SIM, and if not then it is in memory: it is never taught (or even
`
`suggested) as being stored in neither one. See Ex. 1001, 2:60‒62 (“The plurality of
`
`home network MCC and MNC pairs may be stored in memory of the mobile station
`
`or, alternatively, on a Subscriber Identify Module (SIM).”); 3:46–49 (same); 12:41‒
`
`
`

`
`
`
`
`
`
`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`
`13:20 (“[M]emory 502 may store a list 510 of home network MCC/MNC pairs . . . .
`
`In an alternative embodiment, the SIM 262 . . . may include the same or similar
`
`information.”); 13:60‒63 (“The[] multiple MCC/MNC pairs may be stored in a
`
`Home Public Land Mobile Network (HPLMN) list on a Subscriber Identity Module
`
`(SIM). Alternatively, the multiple MCC/MNC pairs may be stored in memory of
`
`the mobile station.”); 15:1–3 (“The plurality of home network MCC and MNC pairs
`
`may be stored in memory of the mobile station or, alternatively on a Subscriber
`
`Identify Module (S[I]M).”). The specification contemplates a method where an
`
`HPLMN list is necessarily accessible, whatever the location, in order to determine
`
`whether to display the home network name. See, e.g., Ex. 1001, 2:51‒55 (“After the
`
`network is selected, the received MCC and MNC pair is compared with a plurality
`
`of home network MCC and MNC pairs which are associated with a single home
`
`network display name.”); 3:38‒41 (same); 14:60‒63 (same).
`
`It defeats the very purpose of the patent—and the alleged inventiveness over
`
`the prior art—to include the possibility that there is no HPLMN list anywhere. The
`
`objective of the ’933 patent is to reduce consumer confusion over whether she is
`
`incurring roaming charges. See Ex. 1001, 2:1‒8. Claiming a method in which there
`
`may be no HPLMN list nullifies this objective.

`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`At bottom, the specification of the ’933 patent wholly fails to convey to a
`
`POSITA a method where the HPLMN list is not present in either the SIM or
`
`memory. See Ex. 1029, ¶¶ 21–23.
`
`B.
`
`There Is No Support in the ’933 Patent for Steps Being Performed
`“Only If” Conditions Are Met As Claimed in New Limitation (2)
`
`Similarly, there is no support for limitation (2), in which the steps of claim 1
`
`(e.g., checking whether an MCC/MNC pair correspond to a home network) are
`
`performed “only if” a certain condition is met. To the contrary, the patent describes
`
`a method that mandatorily performs the steps of claim 1.
`
`The mandatory nature of the steps of claim 1 is readily illustrated by the
`
`patent’s Figure 7. It shows a “flowchart” of the patented method, (Ex. 1001, 13:49),
`
`including every step recited in claim 1: scanning MCC/MNC pairs in the coverage
`
`area (704), selecting and registering with one (706-712), comparing that network
`
`with a plurality of home MCC/MNC pairs (716), and displaying the network name
`
`depending on whether it is a “home” network (718-722). These steps involve two
`
`conditional branch points in the flowchart depending on two comparing steps:
`
`whether the received MCC/MNC pair (706) and selected MCC/MNC pair (716)
`
`match a home network MCC/MNC pair. But all the other steps are mandatory: the
`
`flowchart shows no option not to perform them, and no condition under which they
`
`would be avoided. In particular, there is no option not to perform the comparing
`
`step using the home network list of MCC/MNC pairs. See Ex. 1001, 14:6‒9 (“Next,
`
`
`
`9
`
`
`
`
`
`
`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`
`the mobile station compares the received MCC and MNC pair [of the registered
`
`network] with each one of the multiple home network MCC/MNC pairs (step
`
`716).”); see also, e.g., id. at 14:17‒20 (“[A]lthough the method of FIG. 7 focuses on
`
`the use of only an MCC and MNC pair, the method may include the use of a Location
`
`Area Code (LAC) in addition to the MCC and MNC . . . .” (emphasis added)).
`
`Accordingly, the patent conveys a method that mandatorily comprises the steps of
`
`claim 1, including the step of using an HPLMN list in a comparing step. It is
`
`incompatible with—and, at the very least, fails to convey—the conditional “only if”
`
`limitation of the proposed substitute claims.
`
`The conditional “only if” limitation runs counter to the fundamental purpose
`
`of the patent. The entire ’933 patent is directed to “name displaying methods.” See,
`
`e.g., Ex. 1001, Title (“Name Displaying Methods”); Abstract (“Home network name
`
`displaying methods … are disclosed.”); 2:42 (“Home network name displaying
`
`methods … are described herein.”). The inventive advantage alleged by the
`
`’933 patent relates to displaying a single home network name for multiple home
`
`networks. See id. at 3:49‒52. But under new limitation (2), where the steps of claim
`
`1 may be skipped, the claims encompass methods where no name is displayed
`
`whatsoever. That is, where the “display[ing]” steps of claim 1 are skipped, the
`
`claims fail to instruct any method of displaying a name at all, regardless of whether
`
`it is a home network. Plainly, this new conditional limitation was never
`
`
`
`10
`
`
`
`
`
`
`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`
`contemplated and therefore not disclosed in the original patent. See Ex. 1029, ¶¶ 24–
`
`29.
`
`C. There Is No Support for the “Test” Element of New Limitations (1)
`and (3)
`
`New limitations (1) and (3) together require running a test, at specific times,
`
`to determine whether the HPLMN list is stored in the memory of the mobile station,
`
`in the SIM, or neither. There is no such test disclosed in the specification of the
`
`’933 patent. In the specification, a test is run to determine the location of the
`
`HPLMN list as between the SIM and memory, not to determine its availability at all.
`
`For example, Patent Owner cites a passage that states that the described test is “to
`
`identify the availability of such a list on the SIM and a similar backup list on the
`
`mobile station.” Ex. 1002, 25. There are two alternative tests disclosed in the
`
`’933 patent: one is “by testing if a predetermined designated area of memory on the
`
`SIM includes this list or associated data” and the other is “testing if a version number
`
`of the SIM corresponds to having such a multiple home network list.” Id. Neither
`
`of these disclosed tests is designed to check whether an HPLMN list exists at all.
`
`Rather, these tests check whether there is an HPLMN list in the SIM card, and if
`
`there is not, it is assumed that the list resides in memory. See Ex. 1029, ¶¶ 30–32.
`
`The ’933 patent thus lacks written description for all three proposed new
`
`limitations. For this reason alone Patent Owner’s motion should be denied.

`
`IV. THE PROPOSED AMENDMENTS RENDER THE CLAIMS
`INDEFINITE
`
`The proposed substitute claims are indefinite under 35 U.S.C. § 112 because
`
`they are internally contradictory and it is not clear to a POSITA what steps (if any)
`
`would infringe the claims. Specifically, claim 1 is a method that requires using an
`
`HPLMN list that is stored either in the SIM or in memory, yet the proposed substitute
`
`dependent claims suggest that the HPLMN may be stored in neither. Furthermore,
`
`claim 1 requires practicing specific steps, yet the proposed substitute dependent
`
`claims make these previously mandatory steps optional.
`
`Under Section 112, claims are invalid as indefinite if they fail to “inform those
`
`skilled in the art about the scope of the invention with reasonable certainty.”
`
`Nautilus, Inc. v. BioSig Instruments, Inc., 572 U.S. 898, 910 (2014). Claims fail this
`
`requirement if the patent fails to define their scope in a logically consistent,
`
`unambiguous way. See Allen Eng’g Corp. v. Bartell Indus., Inc., 299 F.3d 1336
`
`(Fed. Cir. 2002) (holding claim indefinite where claim limitation was contradicted
`
`by specification); IQASR LLC v. Wendt Corp., 825 F. App’x 900, 906 (Fed. Cir.
`
`2020) (“contradictory examples in the specification” can render a claim
`
`“indefinite”); Infinity Comput. Prods., Inc. v. Oki Data Ams., Inc., 987 F.3d 1053,
`
`1059–60 (Fed. Cir. 2021) (holding claim indefinite because claim term was defined
`
`two contradictory ways in prosecution history); Teva Pharm. USA, Inc. v. Sandoz,
`
`Inc., 789 F.3d 1335, 1341‒45 (Fed. Cir. 2015) (same).

`

`Motion to Amend in IPR2020-01157
`
`Here, two of the new limitations render the substitute claims internally
`
`contradictory. Pursuant to pre-AIA 35 U.S.C. § 112 ¶ 4, “[a] claim in dependent
`
`form shall be construed to incorporate by reference all the limitations of the claim to
`
`which it refers.” As explained above, original claim 1 (from which the substitute
`
`claims depend) recites a method relying on the use of an HPLMN list which is stored
`
`either in a SIM or in memory. Specifically, it recites, in pertinent part, “using a
`
`plurality of home network MCC and MNC pairs from the HPLMN list stored on a
`
`Subscriber Identify Module (SIM) . . . and otherwise using a plurality of home
`
`network MCC and MNC pairs stored in memory of the mobile station.” Ex. 1001
`
`(’933 Patent), 16:5‒11.
`
`The proposed substitute claims, however, add a contradictory third option:
`
`that the HPLMN is stored in neither. Specifically, each proposed substitute claim
`
`depends on claim 1 and recites “[t]he method of claim 1, wherein . . . the HPLMN
`
`list, a plurality of home network MCC and MNC pairs, is stored in the memory of
`
`the mobile station, in the SIM, or neither.” PO Mot. at 16. Thus the substitute claims
`
`simultaneously recite an “HPLMN list stored on a Subscriber Identify Module (SIM)
`
`. . . and otherwise . . . stored in memory” and then later, an “HPLMN list . . . stored
`
`in the memory of the mobile station, in the SIM, or neither.” See id. This is plainly
`
`contradictory. See Ex. 1029, ¶¶ 38–40. Based on this contradiction alone, the claims
`
`are indefinite. See id. ¶¶ 37, 44.

`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`But the confusion does not stop there: it is compounded by the conditional
`
`limitation (2). Each proposed substitute claim incorporates “the method of claim 1”
`
`(see (pre-AIA) 35 U.S.C. § 112 ¶ 4) —that is, a mandatory, unconditional, multi-
`
`step method including “scanning” for mobile networks in a coverage area, “selecting
`
`and registering” with one such network, “comparing” the network’s MCC and MNC
`
`codes to stored code pairs in an HPLMN list, and “display[ing]” a network name
`
`whose identity depends on the outcome of the comparing step. Ex. 1001 (’933
`
`Patent) at 15:56‒16:23. All of these steps are performed, regardless of how any test
`
`or condition may turn out. However, the proposed amendments subsequently add
`
`conditional limitation (2): “implementing the steps of claim 1 only if the HPLMN
`
`list is contained on the mobile station’s SIM or in its memory.” This creates another
`
`contradiction: the method of claim 1 is unconditional, but the new claims instruct
`
`not to perform it unless a certain condition is met. Thus, it is unclear to a POSITA
`
`whether the steps of claim 1 (which are incorporated into the substitute claims) must
`
`ever be performed at all. See Ex. 1029, ¶¶ 41–43.
`
`Courts consistently hold such claims invalid as indefinite under Section 112.
`
`For example, in Virtual Solutions, LLC v. Microsoft Corp., the patent challenger
`
`“unearthed an apparent logical contradiction within claim 1”—namely, that one
`
`limitation identified a “physical characteristic signal” as “including position
`
`information,” while a later limitation required “position information and said at least
`
`
`
`14
`
`
`
`
`
`
`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`
`one physical characteristic signal.” 925 F. Supp. 2d 550, 561‒62, 566 (S.D.N.Y.
`
`2013), aff’d, 540 F. App’x 997 (Fed. Cir. 2013) (emphases added). The challenger
`
`argued that the claims thus “require[d] that ‘physical characteristic signal’ both
`
`include and exclude ‘position information,’ which . . . is logically impossible.” Id.
`
`at 562. The court agreed, and held that the “logical contradiction” met the burden
`
`of “proving invalidity by clear and convincing evidence.” Id. at 566.
`
`A similar contradiction invalidated the claims in Synchronoss Technologies,
`
`Inc. v. Dropbox Inc., 389 F. Supp. 3d 703 (N.D. Cal. 2019), aff’d, 987 F.3d 1358
`
`(Fed. Cir. 2021). The patent challenger argued the patent was indefinite because a
`
`logical “impossibility permeates all of the claims: the claims require ‘generating a
`
`[single] digital media file’ that itself ‘compris[es] a directory of digital media files.’”
`
`Id. at 714. The court agreed, even though expert testimony suggested that the
`
`contradiction came down to errors in claim drafting. Id. at 715. Even if “the
`
`impossibility of [the] claim, as written” was so evident that a skilled artisan “would
`
`understand that [the claim] means something other than what is written,” that only
`
`confirms the claim’s insoluble indefiniteness. Id.
`
`Because the proposed substitute claims likewise contain contradictions, they
`
`are indefinite under Section 112. See Ex. 1029, ¶¶ 34, 37, 44.

`
`
`V. THE PROPOSED AMENDMENTS IMPERMISSIBLY BROADEN
`THE CLAIMS
`
`To the extent the proposed substitute claims are interpreted to negate the steps
`
`of independent claim 1 in circumstances where there is no HPLMN list, the
`
`amendments cover embodiments that would not have infringed the original patent
`
`and therefore impermissibly enlarge the scope of the claims of the patent.
`
`A proposed amendment “may not enlarge the scope of the claims of the
`
`patent” regardless of whether that scope would otherwise be patentable. 35 U.S.C.
`
`§ 316(d)(3); see also 37 C.F.R. § 42.221(a)(2) (“A motion to amend may be denied
`
`where . . . [t]he amendment seeks to enlarge the scope of the claims of the patent”).
`
`An amendment enlarges the scope of the patent “if it contains within its scope any
`
`conceivable [embodiment] which would not have infringed the original patent.” In
`
`re Cuozzo Speed Techs., LLC, 793 F.3d 1268, 1283 (Fed. Cir. 2015), aff’d, 136 S. Ct.
`
`2131 (2016). Accordingly, an amended “claim cannot be broader in any respect,
`
`even if it is narrowed in other respects.” Senju Pharm. Co. v. Apotex Inc., 746 F.3d
`
`1344, 1352 (Fed. Cir. 2014).
`
`As explained above, independent claim 1 recites a list of specific steps to be
`
`taken, which include “using a plurality of home network MCC and MNC pairs from
`
`the HPLMN list stored on a Subscriber Identify Module (SIM) . . . and otherwise
`
`using a plurality of home network MCC and MNC pairs stored in memory of the
`
`mobile station.” Ex. 1001 (’933 Patent), 16:5‒11. Claim 1 further requires
`
`
`
`16
`
`
`
`
`
`
`
`
`
`Petitioners’ Opposition to Patent Owner’s
`Motion to Amend in IPR2020-01157
`
`
`displaying a network name, either a “home network display name” or “an alternate
`
`display name,” depending on whether the MCC/MNC pair of a selected network is
`
`found in the HPLMN list. Id. at 16:13‒22. Thus, claim 1 would not be infringed
`
`where there is no HPLMN list in either the SIM or memory such that no comparison
`
`is made to determine what network name to display. Indeed, no independent claim
`
`of the ’933 patent would be infringed in these circumstances. See Ex. 1029, ¶¶ 47–
`
`53.
`
`The proposed substitute claims, however, sweep into the scope of the
`
`’933 patent embodiments in which there is no HPLMN list stored in the SIM or
`
`memory, such that no comparison is made and no network name is displayed. The
`
`proposed substitute claims do this by introducing a conditional limitation. Under
`
`binding precedent of
`
`the Board, such conditional
`
`limitations encompass
`
`embodiments where the condition is not met and the conditional steps are not
`
`performed. Ex Parte Schulhauser, No. APPEAL 201
