`
`I. INTRODUCTION
`Petitioner Samsung Electronics America, Inc., filed a Petition
`(Paper 1, “Pet.”) requesting an inter partes review of claims 10–20 of U.S.
`Patent No. 6,836,654 B2 (Ex. 1001, “the ’654 patent”). Patent Owner
`Uniloc 2017 LLC filed a Preliminary Response. Paper 6 (“Prelim. Resp.”).
`Having considered the Petition and Preliminary Response, we
`conclude the Petition should be denied for the reasons discussed below.
`
`II. BACKGROUND
`A. Related Matters
`The parties identify a number of district court proceedings involving
`the ’654 patent. Pet. 1; Paper 3, 2. Of the identified district court
`proceedings, Petitioner is involved in one, specifically Uniloc 2017 LLC v.
`Samsung Elecs. Am., Inc., Case No. 2-18-cv-00508 (E.D. Tex.) (hereafter
`“the district court proceeding”). Additionally, Petitioner has filed another
`Petition challenging the ’654 patent in IPR2019-01218.

`
`
`B. The Asserted Grounds of Unpatentability
`Petitioner contends that claims 10–20 of the ’654 patent are
`unpatentable based on the following grounds:

`Matsukida, Alos, Miller5
`
`Petitioner also relies on the Declaration of Zygmunt J. Haas, Ph.D.
`(Ex. 1002).
`C. The ’654 Patent
`The ’654 patent relates to protecting against theft of a mobile
`radiotelephony device. Ex. 1001, code (57). The ’654 patent notes a
`previously disclosed method of protecting a radiotelephone by creating a
`link between the device and a particular user identification module and
`preventing normal use of the device in the event that the user identification
`module installed in the device is not the linked user identification module.

`(2011), amended 35 U.S.C. § 103 effective March 16, 2013. Because the
`’654 patent has an effective filing date prior to the effective date of the
`applicable AIA amendment, we refer to the pre-AIA version of § 103.

`
`IPR2019-01219
`Patent 6,836,654 B2
`
`Id. at 1:21–29. The ’654 patent laments that this method may allow use of a
`lost or stolen device until the user alerts an operator and the network blocks
`use of the identification module linked to the device. Id. at 1:30–36.
`To address this issue, the ’654 patent discloses a method of blocking
`normal use of a radiotelephony device that has a user identification module.
`Id. at 1:39–50. Specifically, the ’654 patent discloses blocking normal use
`of the radiotelephony device in response to confirmation of the user
`identification module and detection of a period of inactivity of the device.
`Id. Consequently, when the device is lost or stolen, by the time a third party
`has the device, “it has most probably been inactive for a period of time that
`is sufficiently long for its normal operation to be blocked.” Id. at 1:51–54.
`“Thanks to the invention the lost or stolen device becomes totally unusable.”
`Id. at 1:59–60.
`
`D. Illustrative Claim
`Claims 10 and 17 are independent. Each of claims 11–16 and 18–20
`depends, directly or indirectly, from one of independent claims 10 and 17.
`Claim 10 is illustrative and recites:
`10. A method of protecting a mobile radiotelephony device, the
`method comprising:
`verifying a user identification module mounted inside the mobile
`radiotelephony device is linked to the mobile radiotelephony
`device;
`detecting a period of inactivity of the mobile radiotelephony
`device during a normal operation of
`the mobile
`radiotelephony device, wherein the normal operation includes
`a processing of all outgoing calls;
`preventing the normal operation of the mobile radiotelephony
`device in response to the verification of the linked user

`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`
`identification module and in response to the detection of the
`period of inactivity of the mobile radiotelephony device.
`Ex. 1001, 5:27–40.
`
`III. ANALYSIS
`A. Claim Construction
`In an inter partes review for a petition filed on or after November 13,
`2018, the “[claims] of a patent … shall be construed using the same claim
`construction standard that would be used to construe the [claims] in a civil
`action under 35 U.S.C. § 282(b), including construing the [claims] in
`accordance with the ordinary and customary meaning of such claims as
`understood by one of ordinary skill in the art and the prosecution history
`pertaining to the patent.” Changes to the Claim Construction Standard for
`Interpreting Claims in Trial Proceedings Before the Patent Trial and Appeal
`Board, 83 Fed. Reg. 51,340 (Oct. 11, 2018) (codified at 37 C.F.R.
`§ 42.100(b) (2019)) (amending 37 C.F.R. § 42.100(b) effective November
`13, 2018); see also Phillips v. AWH Corp., 415 F.3d 1303, 1312–14 (Fed.
`Cir. 2005). Only those terms that are in controversy need be construed, and
`only to the extent necessary to resolve the controversy. See Nidec Motor
`Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.
`Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795,
`803 (Fed. Cir. 1999)).
`Petitioner “believes that no express construction is necessary to assess
`whether the prior art reads on the challenged claims.” Pet. 6. Patent Owner
`does not dispute this contention.
`For purposes of this decision, we need not construe expressly any
`claim terms.

`
`
`B. Alleged Obviousness over Nokia and Alos
`1. Overview of Nokia
`Nokia discusses “the Nokia 9000i Communicator, the versatile
`communications tool you need to stay connected to the office when you are
`out.” Ex. 1004, 7. Nokia explains that the 9000i Communicator has two
`interfaces, including a phone interface, and a communicator interface. Id. at
`7–8.
`
`For the first start-up, Nokia instructs the user “[i]nstall the SIM card
`and switch on the phone interface before opening the communicator
`interface. In most locations, this will configure the settings for your voice
`mail and the SMSC.” Id. at 10. Nokia instructs the reader to then perform
`certain other steps for configuring the device’s settings and completing the
`start-up procedure. Id. at 11.
`Nokia discusses the option of locking the communicator to prevent
`outgoing calls. Id. at 81. Nokia also explains that “[i]f autolock is on, the
`communicator will lock automatically after the defined inactivity period.”
`Id.
`
`2. Overview of Alos
`Alos seeks to solve the problem of individuals using a radio-telephone
`device either after it has been misappropriated or after expiration of an
`authorized period of use for the device. Ex. 1005 ¶¶ 1–5. Alos teaches
`activating radio means of a mobile radio-telephone terminal with a chip
`card. Id. ¶¶ 6, 9. Alos explains that “the terminal has matching means
`which control the action of the chip card upon the radio means. The
`terminal is thus personalized and the card is linked thereto.” Id. ¶ 9. In one
`
`6
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`embodiment, the matching means includes memory means containing data
`that is matched to data in memory means of the chip card. Id. ¶ 14.
`Controlling comparator means can read the chip card’s memory means and
`“authorize activation of the radio means only after the said match has been
`verified.” Id.
`Alos discloses an exemplary radio terminal in connection with its
`Figure, which is reproduced below.
`
`
`Alos’s Figure shows terminal 1, which is “a radio terminal, for example, for
`cellular telephony.” Id. ¶ 17. Terminal 1 includes keypad 2, transcoding or
`encrypting unit 3, and connector/reader 4. Id. Terminal 1 also includes
`memory 5, well as comparator 6, and radio transceiver unit 7. See id. ¶ 18.
`Memory 5 includes memory zone 522. Id.
`Connector/reader 4 can receive connector 14 of chip card 10. Id. ¶ 17.
`Chip card 10 includes comparator 11 and memory 12. Id. ¶ 18.
`
`7
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`
`Comparators 6 and 11 control activation and deactivation of radio
`transceiver unit 7. Id. Comparator 11 connects to unit 3 through
`connectors 4, 14. Id. Comparator 11 also has a second input connected to
`memory 12. Id. Comparator 6 connects to zone 122 of memory 12, as well
`as memory zone 522 of memory 5. Id.
`
`3. Discussion
`Petitioner asserts that Nokia discloses most of the limitations of
`claims 10–20. Pet. 7–49. Anticipating that Patent Owner might argue “that
`‘linked’ in claim 10 requires storing the same data in the identification
`module and mobile radiotelephony device,” Petitioner argues that “such a
`link would have been obvious in view of Alos.” Id. at 10. Petitioner
`contends that “Alos describes a method of determining whether a SIM card
`is linked to a mobile terminal based on whether the same data is stored on
`both the SIM card and the device.” Id.
`Petitioner argues that it would have been obvious to combine these
`“teachings of Alos with the teachings of Nokia to verify that the SIM card
`and device in Nokia are linked, similar to as taught in Alos.” Id. at 12.
`Petitioner asserts that Nokia and Alos are analogous art and that a person of
`ordinary skill in the art would have expected success in applying its
`teachings to Nokia’s. Id. Petitioner also argues that a person of ordinary
`skill in the art would have understood “that incorporating the teachings of
`Alos, which ensures that a terminal and a linked SIM card can only be used
`together, would have improved security with respect to both Nokia’s
`Communicator and the SIM card—goals expressed by Nokia.” Id. at 13.
`
`8
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`
`At this stage, there is a dispute regarding whether Petitioner has
`shown adequately that Nokia qualifies as a printed publication. Petitioner
`contends that Nokia qualifies as prior art under 35 U.S.C § 102(b), arguing
`that Nokia “was published and distributed along with the 9000i
`Communicator at least as early as October 1997.” Pet. 4. In support of its
`contention that Nokia constitutes a printed publication, Petitioner
`characterizes the Nokia 9000i as “a groundbreaking device in 1997” with a
`“widely heralded” release. Id. at 73 (citing Exs. 1010–1013). Petitioner
`notes that Nokia has been cited as prior art in many other proceedings at the
`Board. Id. Petitioner also identifies “an alternative reproduction with
`identical disclosures that indicates it was printed in April 1998” as evidence
`of Nokia’s status as a printed publication. Id. at 73–74. Additionally,
`Petitioner cites declaration testimony of Jari Toivanen that he was “a
`member of the team responsible for developing the . . . Nokia 9000i
`Communicator” and that “Nokia publicly distributed a user’s manual for the
`Nokia 9000i Communicator by at least October 1997.” Id. at 74 (citing Ex.
`1017, 1).
`Patent Owner argues that Petitioner’s evidence does not support its
`contention that Nokia is a printed publication. Prelim. Resp. 7–10. Patent
`Owner argues that reliance on the Nokia Communicator Owner’s manual in
`other Board proceedings does not obviate Petitioner’s burden to show the
`exhibit it relies on qualifies as a printed publication. Id. at 9. Noting that
`Exhibits 1010–1013 look like “printouts from the ‘Wayback Machine’
`website” (id. at 8), Patent Owner faults Petitioner for providing no testimony
`to authenticate these exhibits to any degree (id. at 8). Patent Owner argues
`
`9
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`that the unsworn declaration of Jari Toivanen fails to meet multiple
`requirements for a declaration or affidavit in this proceeding. Id. at 9–10.
`Additionally, Patent Owner faults Mr. Toivanen’s testimony as conclusory
`with respect to the alleged public distribution of Nokia. Id. at 10.
`Patent Owner raises valid concerns regarding Petitioner’s evidence of
`Nokia’s printed publication status. For the reasons identified by Patent
`Owner, Exhibits 1010–1013 and the declaration of Mr. Toivanen ultimately
`may provide little or no support for Petitioner’s assertion that Nokia
`constitutes a printed publication. Aside from this, frequent reliance on the
`Nokia Communicator owner’s manual as prior art in other Board
`proceedings has limited persuasive value regarding whether Petitioner has
`shown that the exhibit on which it relies qualifies as a printed publication.
`To the extent these issues alone do not prove fatal to the Petition, they raise
`significant questions regarding whether it would be an efficient use of Board
`resources to conduct inter partes review.
`
`C. Alleged Obviousness over Matsukida and Alos
`1. Overview of Matsukida
`Matsukida describes an increasing demand for mobile devices for
`mobile communications corresponding with increasing incidence of
`unauthorized use. Ex. 1021 ¶ 1. As a result, Matsukida notes demand for a
`dial lock function to prevent unauthorized use. Id. Figure 1 of Matsukida is
`reproduced below.
`
`10
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`
`
`Figure 1 of Matsukida “is a view of the principle of the present invention.”
`Id. ¶ 7.
`Figure 1 shows the interaction of various means. Included in Figure 1
`is operation means 1 “for carrying out an operation for putting the mobile
`device in dial lock state.” Id. ¶ 7. Storage means 2 stores information
`indicative of either a dial lock disengaged state or a dial lock state. Id. ¶ 8.
`Second storage means 3 stores a secret code. Id. Input means 4 allows entry
`of the secret code. Id. Cross-reference means 5 cross-references the
`11
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`inputted secret code and the secret code in storage means 3. Id. In the event
`the secret codes match, cross-reference means 5 provides a dial lock
`disengage instruction to first storage means 2. Id. ¶ 9.
`First calculation means 7 determines the elapsed time from when dial
`lock is disengaged. Id. ¶ 10. Third storage means 9 stores first set time t1,
`which is the time “from disengagement of dial lock to automatic
`[reengagement] of the dial lock state.” Id. ¶ 11. First comparison means 11
`compares the calculated time from first calculation means 7 with first set
`time t1. Id.
`Monitoring means 6 detects when a call ends. Id. ¶ 12. Second
`calculation means 8 determines the time elapsed from the end of the call
`detected by monitoring means 6. Id. Fourth storage means 10 stores
`“second time t2 from completion of a call to automatic review engagement
`of a dial lock state.” Id. ¶ 13. Second comparison means 12 is “for
`comparing the calculated time and the second calculation means 8 and the
`second set time t2, and detecting that the calculated time has exceeded the
`second set time t2.” Id.
`When either comparison means 11 or comparison means 12 detects
`time excess, automatic setting means 13 stores in first storage means 2
`information indicating a dial lock state. Id. ¶ 14.
`
`2. Discussion
`Petitioner contends that Matsukida teaches most of the limitations of
`claims 10–12 and 14–20. Pet. 49–70. Petitioner notes that Matsukida does
`not disclose expressly a “user identification module.” Id. at 50. Petitioner
`argues, however, that Alos teaches a user identification module in the form
`
`12
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`of its SIM card. Id. Petitioner argues that it would have been obvious to
`combine the teachings of Alos with Matsukida because a person of ordinary
`skill in the art would have understood that “incorporating the teachings of
`Alos relating to a linked SIM card would have improved mobile device
`security—a goal also expressed by Matsukida (Ex. 1021, ¶¶1, 5-6, 51-52,
`54-55)—as well as SIM card security.” Id. at 50–51. Petitioner further
`argues that the combination would have been obvious due to the ubiquity
`of SIM card use at the time, as well as the simplicity of implementing the
`technology. Id. at 51–52. At this stage, there are no disputes between the
`parties regarding the substance of Petitioner’s contention that claims 10–
`12 and 14–20 would have been obvious over Matsukida and Alos.
`
`D. Alleged Obviousness over Matsukida, Alos, and Miller
`1. Overview of Miller
`Miller explains that radiotelephone systems use a SIM card inside a
`radiotelephone device to “provid[e] subscriber identification, billing
`information and other information concerning the operation of the
`radiotelephone.” Ex. 1022, 1:12–17. According to Miller, “[i]n the present
`telecommunications environment, SIM cards are used to allow the SIM card
`holder to have access to any telecommunications device such as a cellular
`telephone which will receive the SIM card.” Id. at 1:34–37. Miller desires
`“to provide for limited use of subscriber units,” in order to reduce
`misappropriation or theft of subscriber units. Id. at 1:42–50.
`
`2. Discussion
`Claim 13 recites “wherein the prevention of the normal operation of
`the mobile radiotelephony device prevents all transmissions of non-
`13
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`emergency outgoing calls and permits all transmissions of emergency
`outgoing calls.” Ex. 1001, 5:52–55. Petitioner contends that “[a]lthough
`Matsukida “does not expressly disclose permitting outgoing emergency calls
`while in the dial lock state, such a commonsense, widely-used functionality
`would have been obvious in view of Miller.” Pet. 71. Petitioner asserts that
`Miller discloses security features that may be averted for emergency calls.
`Id. at 71–72. Arguing that Miller “is in the same field of mobile device
`security,” Petitioner argues it would have been obvious to combine its
`teachings with those of Matsukida and Alos, explaining that a person of
`ordinary skill in the art would have understood the benefits of allowing
`emergency calls even in the absence of a valid SIM card. Id. at 72. At this
`stage, there is no dispute between the parties regarding the substance of
`Petitioner’s contention that claim 13 would have been obvious in view of
`Matsukida, Alos, and Miller.
`
`E. Discretion to Institute under 35 U.S.C. § 314(a)
`The Director has discretion to institute an inter partes review under 35
`U.S.C. § 314(a) and 37 C.F.R. § 42.108(a). See 35 U.S.C. § 314(a) (stating
`“[t]he Director may not authorize an inter partes review to be instituted
`unless the Director determines that the information presented in the petition .
`. . 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 exercising discretion under 35 U.S.C. § 314(a) and 37
`C.F.R. § 42.108(a), we are mindful of the goals of the AIA—namely, to
`improve patent quality and make the patent system more efficient by the use
`
`14
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`of post-grant review procedures. See H.R. Rep. No. 112-98, pt. 1, at 40
`(2011).
`Petitioner argues that certain considerations weigh in favor of
`exercising discretion to institute inter partes review. Pet. 74–75. Petitioner
`explains that it presents alternative unpatentability grounds based on Nokia
`and Matsukida because “[t]he Matsukida-based grounds are presented in the
`unlikely event that the Board finds Nokia to not be a printed publication.”
`Id. at 74. Petitioner asserts that it would not prove unduly burdensome to
`evaluate the alternative grounds because of simplicity of the technology and
`similarity between the alternative grounds. Id. at 74–75.
`Additionally, Petitioner argues that it filed the Petition promptly and
`the district court proceeding is in its early stages. Id. at 75. Petitioner notes
`that it filed the Petition “within eight months of Uniloc’s re-filing of its
`lawsuit.” Id. Petitioner also explains that the schedule of the district court
`proceeding includes a claim construction hearing in December 2019 and jury
`selection beginning in July 2020. Id.
`Patent Owner argues that we should exercise our discretion under
`§ 314(a) to deny institution of inter partes review. Prelim. Resp. 3–7. In
`particular, Patent Owner argues that instituting would use Board resources
`inefficiently. Id. at 3. Patent Owner disagrees with Petitioner’s
`characterizations of certain facts. Patent Owner disputes Petitioner’s
`assertion that the district court proceeding is in its early stages. To the
`contrary, Patent Owner argues that the timing of the district court proceeding
`relative to this one closely matches the facts in NHK Spring Co., Ltd. v.
`Intri-plex Technologies, IPR2018-00752, Paper 8 (PTAB Sept. 12, 2018)
`
`15
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`(precedential). Prelim. Resp. 4–5. Patent Owner notes, for example, that
`“jury selection at the start of trial before the district court is set for July 6,
`2020, which is . . . six months prior to conclusion of trial before the Board if
`one were instituted, as in NHK Spring.” Id. at 5. Patent Owner also notes
`the district court schedule includes the claim construction hearing in
`December 2019, as well as the close of expert discovery in March of 2020.
`Id. at 5–6. Additionally, Patent Owner argues that, like NHK Spring, “the
`same grounds proposed in the Petition are included in Petitioner’s invalidity
`contentions in the district court.” Id. at 5.
`Patent Owner also argues that Petitioner’s reliance on this Petition and
`the petition in IPR2019-01218 to challenge the same patent unduly burdens
`the Board and Patent Owner. Id. at 6–7. Patent Owner argues that
`Petitioner’s filing of multiple Petitions challenging the same patent also
`raises concerns about fairness, timing, and efficiency. Id. Patent Owner
`argues that the circumstances are not sufficiently rare to warrant filing two
`Petitions to challenge one patent. Id. at 7.
`We find Patent Owner’s arguments regarding the proper use of our
`discretion more persuasive than Petitioner’s. First, as discussed above in
`Section III.B.3, concerns about whether an inter partes review would be an
`efficient use of the Board’s resources arise from the issues regarding the
`evidence submitted by Petitioner in support of its contention that Nokia
`qualifies as a printed publication.
`Second, Petitioner does not distinguish persuasively the facts here
`from the facts in our precedential decision NHK Spring. Pet. 74–75.
`Petitioner argues that it filed its Petition promptly and the district court
`
`16
`
`
`
`
`IPR2019-01219
`Patent 6,836,654 B2
`
`proceeding is in its early stages. But Petitioner does not identify a
`significant distinction between the timing of the district court proceeding
`here and the facts in NHK Spring. Petitioner acknowledges that jury
`selection in the district court is scheduled for July 6, 2020 (Pet. 75),
`approximately six months before a trial in this proceeding would conclude.
`Petitioner does not explain, and it is not apparent, how this differs from the
`facts of NHK Spring, where the district court trial was set for approximately
`six months before a trial before the Board would have concluded. NHK
`Spring at 20. Additionally, and importantly, Petitioner does not attempt to
`identify a distinction between the unpatentability grounds presented in this
`proceeding and those presented in the district court proceeding, leaving
`undisputed Patent Owner’s assertion that “the same grounds proposed in the
`Petition are included in Petitioner’s invalidity contentions in the district
`court.” Prelim. Resp. 5. Thus, Petitioner does not distinguish the present
`case from NHK Spring, where “the same prior art and arguments” were
`asserted in the district court proceeding and the Board proceeding. NHK
`Spring at 20.
`In view of the foregoing, we determine that the circumstances present
`here, on the whole, weigh in favor of exercising our discretion to deny
`institution under § 314(a).
`
`IV. CONCLUSION
`Taking account of the information presented in the Petition and the
`Preliminary Response, and the evidence of record, we exercise our
`discretion under § 314(a) and deny institution. Accordingly, the Petition is
`denied, and no trial is instituted.
