`I.
`
`INTRODUCTION
`Pursuant to 35 U.S.C. § 313 and 37 C.F.R § 42.107, Patent Owner Cellular
`
`Communications Equipment LLC (“CCE”) respectfully submits this preliminary
`
`response to Sony Mobile Communications (USA) Inc.’s (“Petitioner”) Petition for
`
`Inter Partes Review (“Petition”). A trial should not be instituted in this matter
`
`because Petitioner cannot demonstrate that there is a reasonable likelihood that at
`
`least one of the challenged claims of U.S. Patent No. 8,848,556 (Ex. 1001, the “’556
`
`Patent”) is unpatentable. Specifically, Petitioner attacks the three independent
`
`claims at issue (claims 5, 13 and 21) under 35 U.S.C. § 103(a) using a single
`
`reference (the “Heo” reference). The Heo reference, however, does not disclose at
`
`least one element of each of the independent claims. Petitioner does not attempt to
`
`satisfy this missing element from another source. This deficiency is fatal to the
`
`Petition as a whole. As such, trial should not be instituted.
`
`II. OVERVIEW OF THE ’556 PATENT
`“Carrier aggregation” is a technique that allows a mobile device to use
`
`multiple “component carriers” having different frequency bandwidths for
`
`transmissions to a base station, thereby increasing throughput. ’556 Patent at
`
`1:14-25. These “component carriers” may include a primary carrier provided on the
`
`“primary serving cell,” and additional secondary carriers provided on “secondary
`
`serving cells.” ’556 Patent at 4:23-53. The ’556 Patent discloses an improvement

`
`
`Case IPR2015-01716
`Patent 8,848,556
`
`
`
`
`Paper No. 6
`
`
`related to the timing and generation of power headroom reports in the context of
`
`carrier aggregation.
`
`Prior to carrier aggregation, power headroom reporting was described by
`
`3GPP TS 36.321 (releases 8 and 9). ’556 Patent at 1:28-45. According to TS 36.321
`
`(releases 8 and 9), “a power headroom report is triggered if any of the following
`
`occur”:
`
`a timer called “prohibitPHR-Timer” expires or has expired and the path
`
`loss has changed more
`
`than a predetermined amount, “dl-
`
`pathlossChange” dB, since the transmission of a power headroom
`
`report when the user equipment has uplink resources for new
`
`transmission; a timer called “periodicPHR-Timer” expires; or upon
`
`configuration or reconfiguration of the power headroom reporting
`
`functionality by upper layers, which is not used to disable the function.
`
`’556 Patent at 1:28-45. As this prior standard applies “without carrier aggregation,”
`
`each of the “triggers” disclosed by TS 36.321 (releases 8 and 9) is specific to an
`
`individual carrier. ’556 Patent at 1:28-38. As described below, the ’556 Patent
`
`teaches that these same “triggers” may be used for carrier aggregation. ’556 Patent
`
`at 1:39-45.
`
`The ’556 Patent describes a technique to control the timing and content of
`
`“power headroom” reports to be made in the context of carrier aggregation. Rather
`
`than sending multiple, separate power headroom reports for each component carrier,
`
`the ’556 Patent employs a power headroom report control element that allows for

`Patent 8,848,556
`
`
`
`
`Paper No. 6
`
`
`reporting of multiple component carriers. ’556 Patent at 3:61-4:2; 5:4-12. The
`
`power headroom control element includes a bitmap indicating which power
`
`headroom reports are being reported. Id. For example, a bit set to “1” can indicate
`
`a power headroom report for the corresponding carrier is being included. ’556 Patent
`
`at 5:13-23. A bit set to “0” can indicate that a power headroom report for the
`
`corresponding carrier is not included. Id.
`
`Figure 5 from the Patent illustrates an embodiment in which the fist octet of
`
`the payload is the bitmap of the power headroom report:
`
`
`’556 Patent at 3:34-35; 6:8-10. In this example, the first eight bits indicate which
`
`power headroom reports for the corresponding carriers are being reported. Id. The
`
`individual power headroom reports follow the bitmap. ’556 Patent at Figure 5.

`
`
`Case IPR2015-01716
`Patent 8,848,556
`
`
`
`
`
`
`Paper No. 6
`
`The independent claims each require “a trigger” to cause preparation of the
`
`power headroom control element including the bitmap. Claim 13 of the ’556 Patent
`
`is exemplary:
`
`13. A non-transitory computer readable medium encoded with a
`
`computer program that, when executed in hardware, causes the
`
`hardware to perform a process, the process comprising:
`preparing a power headroom report control element, based on a
`trigger configured by a base station, the trigger determining
`
`when the power headroom report control element is to be sent in
`
`an uplink, the preparing of the power headroom report control
`
`element includes incorporating a bitmap indicating which power
`
`headroom reports are being reported, the preparing of the power
`
`headroom report control element further includes preparing the
`
`bitmap to include bits for power headroom reports for a plurality
`
`of secondary cells; and
`
`sending the prepared power headroom report control element to the
`
`base station.
`
`’556 Patent at claim 13 (emphasis added). Claim 13 expressly sets forth a
`
`relationship between “a trigger” and the preparation of the “bitmap.” Specifically,
`
`the “power headroom report control element” is prepared “based on a trigger
`
`configured by the base station….” The “preparation of the power headroom report
`
`control element further includes a bitmap indicating which power headroom reports
`4
`
`
`

`TELEFONAKTIEBOLAGET LM ERICSSON AND
`ERICSSON INC. EX. NO. 1016

`
`
`Case IPR2015-01716
`Patent 8,848,556
`
`
`
`
`Paper No. 6
`
`
`are being reported….” Thus, the claim requires a link between “a trigger” and the
`
`preparation of the “bitmap.” This is consistent with the ’556 Patent specification,
`
`which teaches that the same triggers disclosed by TS 36.321 (releases 8 and 9) can
`
`be applied to carrier aggregation, and that when power headroom reporting is
`“triggered,” power headroom reports for all “serving” carriers should be reported:
`
`The
`
`‘prohibitPHR-Timer,’
`
`‘periodicPHR-Timer,’
`
`and
`
`‘dl-
`
`PathlossChange,’ are configured by a radio resource controller. Similar
`
`power headroom report triggering could also be applied to carrier
`aggregation. When power headroom reporting is triggered, power
`headroom reports on all the scheduled CC (or serving cells) or
`configured CC (or configured serving cells) should be reported.
`
`’556 Patent at 1:39-45 (emphasis added).
`
`
`
`III. CLAIM CONSTRUCTION
`According to 37 C.F.R. § 42.100(b), a claim in an inter partes review is to be
`
`given its “broadest reasonable interpretation in light of the specification of the patent
`
`in which it appears.” Petitioners have construed the meanings of various claim terms
`
`in the Petition. CCE disputes that Petitioner’s proposed constructions are consistent
`
`with the “broadest reasonable construction in light of the specification” and,
`
`consequently, CCE does not acquiesce to Petitioner’s definitions. CCE, however,
`
`does not believe construction of any claim term or phrase is necessary to deny the
`
`Petition at this stage. CCE reserves its rights to set forth competing claim

`
`constructions in a Response (and with the support of its own expert) if an inter partes
`
`review is instituted.
`
`IV. APPLICABLE LEGAL STANDARDS
`A. Standard for Review
`
`The Board may only grant a petition for inter partes review where “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.” 35 U.S.C. § 314(a); 37 C.F.R. § 42.108(c). Petitioner bears the
`
`burden of showing that this statutory threshold has been met. See Office Patent Trial
`
`Practice Guide, 77 Fed. Reg. 48,756 (Aug. 14, 2012) (“The Board … may institute
`
`a trial where the petitioner establishes that the standards for instituting the requested
`
`trial are met ….”).
`
`B. Obviousness
`
`Section 103 of the Patent Act provides that “[a] patent may not be obtained
`
`… if the differences between the subject matter sought to be patented 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.” 35 U.S.C. § 103(a). The obviousness analysis requires a
`
`number of threshold inquiries. The level of ordinary skill in the art must be
`
`established, the scope and content of the prior art must be determined, and any
`
`differences between the prior art and the claims at issue must be ascertained. Graham
`
`v. John Deere Co. of Kansas City, 383 U.S. 1, 17-18 (1966).

`
`
`
`
`
`
`Paper No. 6
`
`i) Claims Cannot be Found Obvious if an Element is Absent
`
`If a single element of the claim is absent from the prior art, the claims cannot
`
`be considered obvious. See CFMT, Inc. v. YieldUp Int’l Corp., 349 F.3d 1333, 1342
`
`(Fed. Cir. 2003) (“Obviousness requires a suggestion of all limitations in a claim.”)
`
`(citing In re Royka, 490 F.2d 981, 985 (C.C.P.A. 1974)); In re Rijckaert, 9 F.3d
`
`1531, 1534 (Fed. Cir. 1993) (reversing obviousness rejection where prior art did not
`
`teach or suggest all claim limitations); Garmin Int’l, Inc. v. Patent of Cuozzo Speed
`
`Techs. LLC, Case No. IPR2012-00001, Paper 15 at 15 (PTAB Jan. 9, 2013) (refusing
`
`to institute an inter partes review under 35 U.S.C. § 103 where prior art did not
`
`disclose all claim limitations). Furthermore, the claims cannot be obvious in light
`
`of a combination of elements that changes the principle operation of the prior art
`
`reference being applied. See In re Ratti, 270 F.2d 810, 813 (CCPA 1959) (“If a
`
`proposed modification or combination of the prior art would change the principle of
`
`operation of the prior art device being modified, then the teachings of the references
`
`are not sufficient to render the claims prima facie obvious.”). As explained below,
`
`Petitioner has not established a reasonable likelihood that at least one of the
`challenged claims of the ’556 Patent is unpatentable for at least the reason that the
`Heo does not disclose a limitation of the independent claims.
`ii) A Petition Must Address the Graham Factors
`
`While CCE believes the above points of law sufficient to warrant denial of the
`
`Petition under the facts presented, CCE notes (for completeness) that the Petition is
`
`deficient because Petitioner’s obviousness analysis does not comply with the
`7
`
`
`
`Page 12 of 28
`
`TELEFONAKTIEBOLAGET LM ERICSSON AND
`ERICSSON INC. EX. NO. 1016
`
`
`
`Case IPR2015-01716
`Patent 8,848,556
`
`
`
`
`Paper No. 6
`
`
`Graham v. John Deere Co. framework. 383 U.S. 1 (1966). Obviousness is resolved
`
`on a number of factual determinations “including (1) the scope and content of the
`
`prior art, (2) any differences between the claimed subject matter and the prior art,
`
`and (3) the level of ordinary skill in the art.” See, e.g., Eizo Corp. v. Barco N.V.,
`
`IPR2014-00358, Paper 11 at 29 (P.T.A.B. July 23, 2014) (citing Graham, 383 U.S.
`
`at 17-18; KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007)). Petitions for
`
`inter partes reviews “must address the Graham factors.” Eizo Corp., IPR2014-
`
`00358, Paper 11 at 29-30. For example, the Board faulted the petitioner in Eizo
`
`Corp. for failing to identify the differences between the claimed subject matter and
`
`the prior art. Id. at 29-30. In particular, the Board found insufficient the petitioner’s
`
`“conclusory assertion” that “[t]o the extent [the first prior art reference] may not
`
`explicitly teach” the limitation, the second prior art reference “explicitly teaches this
`
`limitation.” Id. at 30. The Board explained that “such an assertion fails to resolve
`
`the exact differences sought to be derived from” the second prior art reference. Id.
`
`(finding that petitioner had not shown a reasonable likelihood of prevailing on that
`
`ground). Numerous other Board decisions have reached the same result. See, e.g.,
`
`Moses Lake Indus., Inc. v. Enthone, Inc., IPR2014-00243, Paper 6 at 18 (P.T.A.B.
`
`June 18, 2014) (faulting petitioner for failing to “explain[] any differences between
`
`the claimed subject matter and the prior art”); Moses Lake Indus., Inc. v. Enthone,
`
`Inc., IPR2014-00246, Paper 6 at 17 (P.T.A.B. June 18, 2014) (same); eBay, Inc. v.
`
`Paid, Inc., CBM2014-00125, Paper 15 at 21 (P.T.A.B. Sept. 30, 2014) (concluding

`

`
`V.
`
`PETITIONER CANNOT SHOW THAT THE CHALLENGED
`CLAIMS ARE UNPATENTABLE UNDER 35 U.S.C. § 103
`
`A. Overview of the Petition
`Petitioner contends that several claims of the ’556 Patent are unpatentable
`
`under 35 U.S.C. § 103. Pet. at 8. Notably, no anticipation argument is asserted.
`
`Specifically, the Petition alleges:
` Independent claims 5, 13, and 21 are unpatentable under 35 U.S.C.
`
`§ 103 in view of a single reference, U.S. Patent No. 8,351,359 (Ex.
`
`1004, “Heo”). Pet. at 8. Although Petitioner also cites to various parts
`
`of three provisional applications to which Heo claims priority,
`
`Petitioner does so only for purposes of arguing that Heo is entitled to
`
`an earlier effective filing date. Pet. at 3.
` Dependent claims 6, 14, and 22 are unpatentable under 35 U.S.C. § 103
`
`in view of Heo. Pet. at 8.
` Dependent claims 8, 16, and 24 are unpatentable under 35 U.S.C. § 103
`
`in view of Heo and U.S. Patent Application Publication No.
`
`2010/0296467 (“Pelletier”) (Ex. 1008). Pet. at 8.
` Dependent claims 8, 16, and 24 are unpatentable under 35 U.S.C. § 103
`
`in view of Heo, Pelletier, and TS 36.213 v8.7.0 (Ex. 1012). Pet. at 8.

`
`
`
`As set forth above, Petitioner’s sole challenge to independent claims 5, 13,

`
`Should the Board decline to institute trial on independent claims 5, 13, and 21, the
`
`Board must also decline to institute trial on all other claims. This is because
`
`Petitioner’s arguments with respect to the dependent claims rely entirely on
`
`Petitioner successfully invalidating the independent claims under 35 U.S.C. § 103 in
`
`view of Heo.1

`B.
`The Heo Reference does not Disclose an Element of Claims 5, 13
`and 21.
`As set forth in Section IV(B), patent claims cannot be found obvious where
`
`an element is not taught, suggested, or disclosed by the prior art. In this case,
`
`independent claims 5, 13 and 21 cannot be found obvious in view of Heo because
`Heo does not disclose “preparing a power headroom report control element, based
`on a trigger configured by a base station….[the preparing / preparation] of the power
`headroom report control element includes incorporating a bitmap ….” (emphasis
`
`added). As explained below, Petitioner and its expert acknowledge that Heo fails to
`
`disclose this limitation. Pet. at 19; Declaration of Bruce McNair (Ex. 1017) p. 26-
`
`27, ¶ 65.
`
`Claims 5, 13, and 21 each include the following language: “preparing a power
`headroom report control element, based on a trigger configured by a base
`
`station….” Claims 5, 13, and 21 further require the power headroom report control
`
`element to include a bitmap:
` Claim 5 states: “the preparing of the power headroom report control
`element includes incorporating a bitmap …”
` Claim 13 states: “the preparing of the power headroom report control
`element includes incorporating a bitmap …”
` Claim 21 states: “preparation of the power headroom report control
`element includes incorporating a bitmap …”

`Patent 8,848,556
`
`
`
`
`Paper No. 6
`
`
`This is consistent with disclosure in the ’556 Patent whereby a single trigger
`
`configured by the base station causes power headroom reports to be sent for multiple
`
`carriers. ’556 Patent at 1:39-45 (“When power headroom reporting is triggered,
`
`power headroom reports on all the scheduled CC (or serving cells) or configured
`
`CC (or configured serving cells) should be reported.”)
`
` As Petitioner admits, Heo discloses numerous embodiments. Pet. at 19. With
`
`respect to the bitmap, the Petition appears to rely on particular embodiment(s) found
`
`at 10:57-60 and 11:4-15 of Heo. Pet. at 18-19. In this disclosure, Heo does not teach
`
`that a single trigger causes preparation of a power headroom control element that
`
`incorporates a bitmap. Heo at 10:42-57. Instead, this embodiment of Heo discloses
`
`sending power headroom reports only for component carriers which have been
`
`individually “triggered”:
`
`In yet another alternative for reporting LTE-A power headroom
`
`via a MAC control element, a UA transmits the PH of only a certain
`
`reporting carrier or of only certain reporting carriers. The disadvantage
`
`of transmitting the PH for all reporting carriers, as described in the first
`
`alternative given above, is that PH information may be reported
`unnecessarily. In an embodiment, to reduce signaling overhead, the
`UA transmits PH information only for a carrier or carriers for which
`a specific event trigger occurs or when that carrier's PUSCH is
`scheduled. Different dl-PathlossChange, periodicPHR-Timer, and/or
`
`prohibitPHR-Timer can be configured for each carrier or for a subset

`
`of carriers. In case where multiple events are triggered, PHs of all
`
`triggered carriers can be transmitted. For example, when the path loss
`
`difference is larger than a preconfigured threshold in carrier #1, UA
`
`would transmit the PH only for carrier #1.
`
`Heo at 10:42-57 (emphasis added). According this embodiment, if one trigger “goes
`
`off,” only one carrier’s power headroom report will be sent. Heo at 10:42-57 (“For
`
`example, when the path loss difference is larger than a preconfigured threshold in
`carrier #1, UA would transmit the PH only for carrier #1”). If two triggers “go
`
`off,” two carrier’s power headroom reports will be sent. Heo at 10:42-57 (“In case
`where multiple events are triggered, PHs of all triggered carriers can be
`transmitted.”). Heo states that reporting power headroom reports only for carriers
`
`that are individually triggered is a mechanism to “reduce signaling overhead.” Heo
`
`at 10:48-51.
`
`
`
`Heo mentions using a bitmap: “To indicate to the access node which reporting
`
`carriers’ PHs are being transmitted, additional signaling, such as a bitmap, is
`
`included with a PH report.” Heo at 10:57-60. Heo, however, does not identify any
`
`association between the carrier-specific triggers and the preparation of the bitmap.
`
`Heo does not teach, suggest, or disclose “preparing a power headroom report control
`element, based on a trigger configured by a base station… [the preparing /
`preparation] of the power headroom report control element includes incorporating
`a bitmap ….” (emphasis added) as recited in the independent claims.

`
`
`
`
`
`
`Paper No. 6
`
`Notably, the Petition admits this limitation is not disclosed by the Heo
`
`reference:
`
`Therefore, to the extent that Heo does not explicitly disclose certain
`
`features of power headroom reporting together in a single embodiment
`(as may be required to find anticipation) (for example preparing a
`power headroom control element including the above-described
`bitmap, based on a trigger periodicPHR-Timer)….
`
`Pet. at 19 (emphasis added). Likewise, Petitioner’s expert admits that Heo does not
`
`disclose a functional relationship between the bitmap and triggers:
`
`It is further noted that the drafters of the Heo patent describe many
`
`features using terms such as “alternatively,” “in an embodiment,” “in
`
`some embodiments,” “in another technique,” etc. However, one of
`
`ordinary skill in the art would have understood that the various
`
`disclosed features, techniques, and methods could be combined and/or
`integrated with each other. For example, although the bitmap and
`triggers are not explicitly described to function together in any
`particular manner, it is obvious that they may simply be considered as
`
`different features or options of Heo’s PHR system.
`
`Declaration of Bruce McNair (Ex. 1017) at 26-27, ¶ 65 (emphasis added). Critically,
`
`Petitioner does not seek to satisfy this missing limitation with disclosure from
`
`another embodiment of Heo (or from another source). Thus, Petitioner has not
`
`shown that Heo discloses the limitation “preparing a power headroom report control

`element, based on a trigger configured by a base station … [the preparing /
`preparation] of the power headroom report control element includes incorporating
`a bitmap ….”
`
`
`
`
`
`Not only does Heo fail to disclose an association between a trigger and the
`
`preparation of the bitmap, the Heo “bitmap” embodiment cited by Petitioner (Heo at
`
`10:42-57) relies on multiple triggers to achieve its stated purpose:
`
`To reduce signaling overhead and to reduce the unnecessary reporting
`
`of power overhead reports, only certain carriers are reported. (Ex. 1004:
`
`10:42-51.) (See also Ex. 1005: ¶ 57; Ex. 1006: ¶ 58; Ex. 1007: ¶ 58.)
`
`For example, triggers, using variables such as dl-PathlossChange,
`
`periodicPHR-Timer, and prohibitPHR-Timer, may be used
`
`to
`
`determine which carriers are to send power headroom reports. (Ex.
`
`1004: 10:51-55.) (See also Ex. 1005: ¶¶ 35, 36; Ex. 1006: ¶¶ 36, 37, 58;
`
`Ex. 1007: ¶¶ 36, 37, 58.)
`
`Pet. at 17-18. As set forth above, the Heo embodiment at issue is expressly
`
`concerned with “reduction of signaling overhead.” Heo at 10:42-51. Heo’s
`
`“bitmap” embodiment purports to achieve reduction in signaling overhead by only
`
`sending power headroom reports for carriers that are individually triggered. Heo at
`
`10:48-51. The Heo “bitmap” embodiment expressly criticizes the practice of
`
`transmitting the PH for all reporting carriers as “unnecessary.” Heo at 10:45-47. If
`
`only one carrier was triggered, only one power headroom report would be sent. Heo
`
`at 10:42-51. Therefore, according to Heo’s disclosure, preparing and sending a

`
`
`
`
`Paper No. 6
`
`
`bitmap designed to report for multiple carriers when only one carrier’s power
`
`headroom report is triggered would increase signaling overhead, thereby defeating
`
`the stated purpose of the embodiment. As discussed above, if the combination of
`
`elements changes the principle of operation of the prior art device being modified,
`
`there is no prima facie case of obviousness. See In re Ratti, 270 F.2d at 813 Id.
`
`
`In summary, the bitmap embodiment of Heo relied upon by Petitioner does
`not disclose “preparing a power headroom report control element, based on a trigger
`
`configured by a base station … [the preparing / preparation] of the power headroom
`report control element includes incorporating a bitmap ….” This is admitted by
`
`Petitioner and its expert. Petitioner fails to satisfy this missing element with other
`
`disclosure from Heo (or from another source). This deficiency, by itself, requires
`
`denying institution. See 37 C.F.R. § 42.104(b)(4) (“The petition must specify where
`
`each element of the claim is found in the prior art patents or printed publications
`
`relied upon”). Additionally, Heo’s teaching of using multiple triggers in connection
`
`with a bitmap cannot be used to disclose use of a single trigger for causing
`
`preparation of a bitmap as this would change the principle of operation of Heo and
`
`be inconsistent with Heo’s stated objectives.
`
`C.
`The Petition and Expert Declaration do not Follow the
`Graham Framework and are Deficient.
`
`
`Petitions for inter partes reviews must address the Graham factors. See
`
`Section IV(B), above. The Petition at issue is wholly deficient in this regard.
