`
`INTRODUCTION
`
`Uniloc 2017 LLC (the “Patent Owner” or “Uniloc”) submits its Patent Owner
`
`Preliminary Response to the Petition for Inter Partes Review (“Pet.” or “Petition”)
`
`of United States Patent No. 7,075,917 (“the ‘917 patent” or “Ex. 1001”) filed by
`
`Apple Inc. (“Petitioner”) in IPR2020-00224.
`
`In view of the reasons presented herein, the Petition should be denied in its
`
`entirety as failing to meet the Petitioner’s burden of proving a reasonable likelihood
`
`of prevailing as to any challenged claim.
`
`Uniloc addresses each ground and provides specific examples of how
`
`Petitioner failed to meet its burden of proof. As a non-limiting example described in
`
`more detail below, the Petition has failed to establish that the primary reference on
`
`the sole ground is prior art, and the Petition fails the all-elements-rule in not
`
`addressing every feature of any of the challenged claims.
`
`II. THE ‘917 PATENT
`
`A. Effective Filing Date of the ‘917 Patent
`
`The ‘917 patent is titled “Wireless Network with a Data Exchange According
`
`to the ARQ Method.” The ‘917 Patent issued on July 11, 2006, from United States
`
`Patent Application No. 09/973,312, filed October 9, 2001, which claims priority to
`
`German Patent Application No. 100 50 117, filed October 11, 2000. The Petition
`
`does not dispute that the effective filing date of the ‘917 Patent is October 11, 2000.
`

`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`
`B. Overview of the ‘917 Patent
`
`The ‘917 Patent discloses various embodiments of a communication network
`
`intended for use in wireless communications. In general terms, the ‘917 Patent
`
`addresses challenges with wireless networks having a radio network controller, and
`
`terminals in communication with the radio network controller. (Ex. 1001; 1:5-7).
`
`Data transmitted between the radio network controller and the terminals is
`
`transmitted through channels predefined by the radio network controller. (Ex. 1001;
`
`3: 57-60). The radio link from the radio network controller to the terminals is referred
`
`to as the downlink, and the radio link from the terminals to the radio network
`
`controller is referred to as the uplink. (Ex. 1001; 3:62-67).
`
`
`
`2
`
`
`
`
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`
`The network may be operated using a layer model, or protocol architecture, in
`
`accordance with a set of standards, known as the 3rd Generation Partnership Project
`
`(3GPP); Technical Specification Group (TSG) RAN; Working Group 2 (WG2):
`
`Radio Interface Protocol Architecture: TS25.301 V3.6.0). (Ex. 1001; 6:9-16).
`
`As explained with reference to Fig. 2 of the ‘917 Patent, the layer model has
`
`three protocol layers: the physical layer PHY, a data connection layer including sub-
`
`layers MAC, for Medium Access Control, and RLC, for Radio Link Control, and the
`
`3
`
`
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`layer RRC for radio resource control. (Ex. 1001, 4:43-48). The RRC layer is
`
`responsible for signaling between the radio network controller and the mobile
`
`terminals. (Ex. 1001, 4:49-51). The sub-layer RLC controls radio links between
`
`remote terminals and radio network controllers. (Ex. 1001; 4:51-53). The layer RRC
`
`controls layers MAC and PHY via control lines 10 and 11. The layer RRC can thus
`
`control the configuration of the MAC and PHY layers. (Ex. 1001, 4:53-56). The
`
`physical layer PHY makes transport links 12 available to the MAC layer (Ex. 1001,
`
`4:56-57). The MAC layer makes logic channels 13 available to the RLC layer. (Ex.
`
`1001, 4:57-58). The RLC layer is available to applications via access points 14. (Ex.
`
`1001, 4:58-59).
`
`Packet data units for transmission are formed in the RLC layer, are packed in
`
`transport blocks in the MAC layer, and provided to the physical layer. The transport
`
`blocks are transmitted between the radio network controller and terminals by the
`
`physical layer. (Ex. 1001, 5:).
`
`Identification of error-affected packets and retransmission of error-affected
`
`packet data units is accomplished in multiple manners. Using the hybrid Automatic
`
`Repeat Request (ARQ) method Type II or Type II, a received packet data unit
`
`affected by an error is buffered and, after additional incremental redundancy, is
`
`decoded together with the received packet data unit affected by error. In the ARQ
`
`method Type II, the incremental redundancy is useless without the buffered, and
`
`4
`
`
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`error-affected, packet. In the ARQ method Type II the incremental redundancy can
`
`be decoded without the buffered, error-affected, packet. A message as to error-free
`
`reception is sent by the receiving device only when the receiving RLC layer
`
`establishes on the basis of an RLC sequence number that packet data units are
`
`lacking. (Ex. 1001; 1:40-43). The RLC sequence number, or packet data unit
`
`sequence number, is transmitted in parallel with the coded transport block or the
`
`incremental redundancy required afterwards, as side information, thereby permitting
`
`the receiving side to detect which coded transport block is concerned or which
`
`buffered coded transport block the additionally transmitted redundance refers to
`
`when a coded transport block is retransmitted (Ex. 1001; 5: As a result, the packet
`
`data unit must be buffered over a long time period until an incremental redundancy
`
`is requested, and then, after successful decoding, the reception may be
`
`acknowledged as correct. (Ex. 1001; 1:43-45). The period of time that the packet
`
`data unit must be buffered is particularly long on the network side, as the physical
`
`layer and the RLC layer are usually located on different hardware components on
`
`the network side. (Ex. 1001; 1:48-50).
`
`The ‘917 Patent addresses the challenge of buffering the error-affected data
`
`for a long period of time by having the receiving physical layer check whether the
`
`coded transport block has been transmitted correctly. (Ex. 1001; 6:9-11). The ‘917
`
`Patent further provides for transmission of an acknowledge command over a back
`
`5
`
`
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`channel between a physical layer of a transmitting device and the physical layer of
`
`a receiving device. (Ex. 1001; 2:30-33). This transmission of the acknowledge
`
`command provides that a correct or error-affected transmission of a transport block
`
`is provided to the transmitting side much more rapidly than previously known. (Ex.
`
`1001; 2:33-36). As a result, a repetition of transmission with incremental redundancy
`
`may be effected rapidly. This enables the receiving side to buffer the received coded
`
`transport block affected by error for a shorter time period. (Ex. 1001;2:38-40). The
`
`memory capacity needed on average for buffering received coded transport blocks
`
`affected by error is reduced. (Ex. 1001; 2:42-44).
`
`Referring to Fig. 3 of the ‘917 Patent, an example is provided.
`
`
`
`6
`
`
`
`
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`
`Here, transport blocks TB0 to TB4, to be transmitted for a time period of two
`
`radio frames RF, each having a duration of one Transmission Time Interval (TTI)
`
`are shown. (Ex. 1001; 6:44-48). Multiple channels, including the physical channel
`
`PHC, which carries the transport blocks, the side information channel SI, which
`
`carries information about the redundancy version and the abbreviated sequence
`
`number of a transport block, and the back channel BC are shown. (See Ex. 1001;
`
`6:27 – 7:16). As the ‘917 Patent explains, the correct or error-affected reception is
`
`checked in the physical layer in the radio frame RF which comes after the
`
`transmission time interval. (Ex. 1001; 6:56-58). Thus, for transport block TB1,
`
`7
`
`
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`which is transmitted during the first radio frame of Fig. 3, error-checking is
`
`performed during the second of the four radio frames shown in Fig. 3, and the
`
`positive acknowledge command ACK is transmitted via back channel BC during the
`
`third radio frame. (Ex. 1001; 6:60-61). The transmission of transport blocks TB2,
`
`TB3 and TB4 is completed during the second of the four radio frames, and error
`
`checking is performed during the third radio frame. During the fourth radio frame,
`
`the positive acknowledgment command ACK for the transport blocks TB4 and TB2,
`
`and the negative acknowledgment command NACK for transport block TB3, are
`
`transmitted via back channel BC (Ex. 1001; 6:62-65).
`
`Further, the ‘917 Patent teaches the use of abbreviated sequence numbers to
`
`reduce the extent of information that is required to be additionally transmitted for
`
`managing the transport blocks and packet data units. (Ex. 1001; 2:45-49). The ‘917
`
`Patent teaches that “abbreviated sequence number is determined by the number of
`
`M coded transport blocks which, on the receiving side, can at most be buffered
`
`simultaneously.” (Ex. 1001, 5:41-44). The ‘917 Patent goes on to state that the
`
`number of M coded transport blocks is the logarithm to the base of 2, rounded to the
`
`next higher natural number. (Ex. 1001, 5:44-44) Thus, the maximum number of
`
`coded transport blocks to be stored is the same as the maximum number of coded
`
`transport blocks that can be buffered simultaneously.

`
`C.
`
`Prosecution History of the ‘917 Patent
`
`The ‘917 Patent issued from U.S. Patent Application Serial No. 09/973,312,
`
`filed October 9, 2001 (the ‘312 Application), which claims priority to German
`
`Application No. 10050117.6, filed October 11, 2000. The ‘312 Application was filed
`
`with 10 claims, including 3 independent claims (Ex. 1002, pp. 13-15). Information
`
`11
`
`
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`Disclosure Statements were filed in the ‘312 Application on January 8, 2002 and
`
`September 22, 2003, identifying: 3rd Generation Partnership Project, Technical
`
`Specification Group Radio Access Network, Report on Hybrid ARQ Type II/III
`
`(Release 2000), 3G TR 25.835 v0.0.0, TS-RAN Working Group 2 (Radio L2 and
`
`Radio L3, France, August 15-21, 2000).
`
`In a first Office Action, mailed September 21, 2005, independent claims 1 and
`
`9-10, were objected to for various informalities and dependent claims 4-8 were
`
`rejected under 35 U.S.C. 112, second paragraph. (Ex. 1002, p. 59-61). The Office
`
`Action confirmed that the Examiner considered the references cited in the
`
`Information Disclosure Statements. (Ex. 1002, pp. 63-64). The Office Action further
`
`included a list of references considered by the Examiner, namely U.S. Patent
`
`Publication No. 2001/0036169 (Ratzel), U.S. Patent Publication No. 2003/0157927
`
`(Yi, et al.) and U. S. Patent Publication No. 204/0246917 (Cheng, et al.). (Ex. 1002,
`
`p. 65). The Ratzel reference discloses, in a digital packet radio receiver network, an
`
`automatic repeat request, or ARQ, in which a very short sequence number is utilized
`
`for space efficiency. (Ex. 1002, p. 99).
`
`An Amendment and Response was filed on January 23, 2006. (Ex. 1002, pp.
`
`68-75). In the Amendment, independent claims 1, 9 and 10 were amended to correct
`
`minor informalities. (Ex. 1002, pp. 69-71). Dependent claims 4, 5, 7 and 8 were
`
`amended to clarify that the recited physical layer may be of the sending side or the
`
`12
`
`
`
`1PR2020-00224
`
`US. Patent No. 7,075,917
`
`transmitting side, and that an acknowledge command may be transmitted form either
`
`the sending side or the transmitting side. (Ex. 1002; p. 70).
`
`The USPTO issued a Notice of Allowance on February 27, 2006. (EX. 1002,
`
`p. 78). The issue fee was paid on May 24, 2006. (EX. 1002; p.85). The application
`
`issued as the ‘917 Patent on July 1, 2006.

`
`IV. THE BOARD SHOULD EXERCISE DISCRETION TO DENY
`INSTITUTION
`
`Uniloc opposes joinder to IPR2019-00973 (“Microsoft IPR”) for the reasons
`
`given in its opposition to the joinder motion. Paper 7. For similar reasons, should
`
`the Board deny the joinder motion, the Board should also exercise its discretion not
`
`to institute a separate trial in this proceeding.
`
`In General Plastic Industrial Co., Ltd. v. Canon Kabushiki Kaisha, Case
`
`IPR2016-01357, slip op. at 15–16 (PTAB Sept. 6, 2017) (Paper 19) (precedential),
`
`the Board articulated a non-exhaustive list of factors to be considered in determining
`
`whether to exercise discretion under § 314(a) to deny a petition that challenges the
`
`same patent as a previous petition. Application of the General Plastic factors is not
`
`limited solely to instances when multiple petitions are filed by the same petitioner.
`
`Valve Corp. v. Elec. Scripting Prods., Inc., Case IPR2019-00062, -00063, -00084,
`
`Paper 11, p. 2 (Apr. 2, 2019) (designated: May 7, 2019). Rather, when different
`
`petitioners challenge the same patent, the Board considers any relationship between
`
`those petitioners when weighing the General Plastic factors. Id.
`
`Here, the first General Plastic factor weighs against institution because Apple
`
`previously filed a petition directed to the same claims of the same patent (in
`
`IPR2019-00259, “Apple ’259 IPR”). Apple’s Petition purports to have complete
`
`overlap with the challenged claims of the Microsoft IPR; and, as noted above, Apple
`
`14
`
`
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`acknowledged conferring with Microsoft, including before filing its IPR. At least
`
`these facts collectively weigh against institution and joinder.
`
`The second factor also weighs against institution and joinder—i.e., whether at
`
`the time of filing the first petition the petitioner knew or should have known of the
`
`prior art asserted in the second petition. Apple acknowledges its second petition
`
`contains overlapping art with its first petition. In addition, Apple does not even
`
`allege the additional art in the instant (second) petition could not have been found
`
`and asserted in its first petition with reasonable diligence.
`
`The third factor also weighs against institution—i.e., “Petitioner’s potential
`
`benefit from receiving and having the opportunity to study Patent Owner’s
`
`Preliminary Response, as well as [the Board’s] institution decisions on the first-filed
`
`petitions, prior to filing follow-on petitions.” While Microsoft did not have the
`
`benefit of the Board’s institution decision in Apple ’259 IPR or Uniloc’s preliminary
`
`response when Microsoft filed its petition, Apple is now seeking to take advantage
`
`of its knowledge of the institution decision in the Microsoft IPR and Uniloc’s
`
`preliminary response. Apple should not be allowed benefit from the preliminary
`
`responses and the institution decisions, which is precisely what would happen if
`
`Apple takes a lead role in the petition it seeks to join or if this Petition were
`
`separately instituted.
`
`15
`
`
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`
`Factors four and five weigh against institution and joinder because Apple
`
`provides no adequate explanation for the time elapsed between the filing of the
`
`Apple ’259 IPR and Apple’s joinder motion. Factors six and seven weigh against
`
`institution and joinder because, as explained above, Apple purports offers a
`
`definition for “understudy” which purports to preserve rights and unnecessarily
`
`complicates the proceeding in a manner that increases the possibility that Board
`
`resolution may be required.
`
`Apple’s attempt to take the second bite at the apple implicates the same
`
`efficiency concerns underpinning General Plastic and the Valve Corporation
`
`opinions. See Valve Corporation v. Electronic Scripting Products, Inc., IPR2019-
`
`00064, -00065, -00085 (PTAB May 1, 2019) (Paper 10) (“Valve II”) (precedential);
`
`Valve Corp. v. Elec. Scripting Prods., Inc., IPR2019-00062, -00063, -00084 (PTAB
`
`Apr. 2, 2019) (Paper 11) (“Valve I”).
`
`V. LEVEL OF ORDINARY SKILL IN THE ART
`
`The Petition proposes a level of ordinary skill in the art of a person having a
`
`bachelor’s degree in electrical engineering, computer science, or the equivalent and
`
`three years of experience working with wireless digital communication systems
`
`including the physical layer of such systems. (Petition, p. 27). The Petition
`
`alternatively proposes that the skilled person would have had a master’s degree in
`
`16
`
`
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`
`electrical engineering, computer science, or the equivalent with an emphasis on
`
`wireless digital communication systems. (Petition, pp. 27-28).
`
`Patent Owner also does not provide its own definition because, even applying
`
`the multiple and varying alternative definitions proposed by Petitioner, Petitioner
`
`has not met its burden. Moreover, the Petition cites to the hybrid ARQ methods
`
`described in the ‘917 Patent itself as support for the level of ordinary skill in the art,
`
`but completely fails to link these particularized subject matter areas to the identified
`
`levels of education and industry experience proposed by Petitioner.
`
`VI. PETITIONER FAILS TO CARRY ITS BURDEN OF SHOWING A
`REASONABLE LIKELIHOOD OF PREVAILING AS TO ANY
`CHALLENGED CLAIM.
`
`Patent Owner demonstrates that Petitioner has failed to carry its burden of
`
`showing a reasonable likelihood of prevailing in showing that any of the challenged
`
`‘917 Patent claims is unpatentable by a preponderance of the evidence. 35 U.S.C.
`
`§316(e). By not addressing additional arguments, Patent Owner in no way concedes
`
`that any argument by Petitioner is correct.
`
`Petitioner has the burden of proof to establish entitlement to relief. 37 C.F.R.
`
`§ 42.108(c). Because the Petition only presents a theory of obviousness, Petitioner
`
`must demonstrate that there is a reasonable likelihood that at least one of the claims
`
`challenged in the petition would have been obvious in view of the references cited
`
`in the Petition. Petitioner “must specify where each element of the claim is found in
`
`17
`
`
`
`
`the prior art patents or printed publications relied upon.” 37 C.F.R. § 42.104(b)(4).
`
`The Board should reject the Petition because Petitioner fails to meet this burden for
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`the sole ground.
`
`The Petition is stylized as presenting the following ground:
`
`Ground Claim(s)
`
`Statute Reference(s)
`
`1-3 and 9-10
`
`103
`
`3G TR25.835 (Ex. 1005) and U.S. Patent
`No.6,507,582 (Abrol) (Ex. 1007)
`
`1
`
`
`
`A. Claim Construction Standard
`
`As of the filing date of the Petition, the standard for claim construction in Inter
`
`Partes Review is the standard of “ordinary and customary meaning of such claim as
`
`understood by one of ordinary skill in the art and the prosecution history pertaining
`
`to the patent.” 37 C.F.R. §42.100(b) (effective November 13, 2018). For all claim
`
`terms, Uniloc requests that the Board adopt the ordinary and customary meaning of
`
`the claim term as understood by one of ordinary skill in the art.
`
`The proposed construction of “back channel” on page 29 of the Petition as a
`
`“channel which is inserted directly between the receiving physical layer and the
`
`sending (or transmitting) physical layer (and not between the RLC layers) for
`
`informing the transmitting side (transmitting terminal or radio network controller)
`
`of the fact that a transport block has not been transmitted error-free”, has not been
`
`shown to constitute the ordinary and customary meaning of the phrase as understood
`
`by one of ordinary skill in the art.

`U.S. Patent No. 7,075,917
`
`
`
`B.
`
`The Petition fails to establish that TR25.835 constitutes prior art
`as to the ‘917 Patent.
`
`The Petition fails to establish that TR25.835 constitutes prior art. First, the
`
`Petition fails to meet the Petitioner’s burden of explaining how TR25.832 allegedly
`
`qualifies as prior art under pre-AIA 35 U.S.C. 102(a) or 102 (b). Second, even if the
`
`Board were to treat the Petitioner here in the manner an Examiner treats a pro se
`
`applicant and conduct a legal analysis on Petitioner’s behalf, the evidence provided
`
`by the Petitioner, namely the Rodermund Declaration (Ex. 1004), does not meet the
`
`Petitioner’s burden here. The Rodermund Declaration makes clear that the version
`
`of TR25.835 that was allegedly available on the 3GPP ftp server was not publicly
`
`accessible by virtue of indexing or cataloging, as the document bore an arbitrary title
`
`that had no information regarding its subject matter. Ex. 1004 ¶25. The Rodermund
`
`Declaration does not state that TR25.835, or a notification as to the uploading of
`
`TR25.835 to the 3GPP server, was distributed by email. See id. Even if a notification
`
`of the uploading of the TR25.835 had been emailed, there was no way for the person
`
`of ordinary skill to subscribe to such emails, as the Rodermund Declaration states
`
`that those notification emails were provided to selected representatives of 3GPP
`
`member companies, not the general public. Id.¶19. Finally, the Petition does not rely
`
`on any presentation or distribution of TR25.835 at a meeting, and Petitioner provides
`
`no documentary evidence whatever to corroborate Rodermund’s unsupported
`
`19
`
`
`
`
`statement that TR 25.835 was presented at a meeting, or even to corroborate that the
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`meeting took place. See Ex. 1004, ¶25.
`
`The Petition’s rationale, on pages 9–10 of the Petition, for the alleged status
`
`of TR25.835 as prior art, fails on multiple grounds. The Petition merely states that
`
`TR25.835 was published by 3GPP in 2000 and publicly available on the 3GPP file
`
`server no later than September 13, 2000. Pet. 9. The Petition does not recite any
`
`applicable standard that TR25.832 must meet to qualify as a printed publication
`
`under pre-AIA 35 U.S.C. §102(a) or 102(b), or explain how the supporting evidence
`
`allegedly demonstrates that the applicable standard is met, thus failing to meet the
`
`minimum standards required to explain the significance of evidence, both under
`
`applicable regulations and under applicable case law.
`
`The Petition fails to meet the requirements of 37 C.F.R. 42.22(a), which states:
`
`Each petition or motion must be filed as a separate paper and must
`
`include:
`
`
`
`
`
`(1) A statement of the precise relief requested; and
`
`(2) A full statement of reasons for the relief requested, including
`
`a detailed explanation of the significance of the evidence including
`
`material facts, and the governing law, rules and precedent.
`
`Here, the required “detailed explanation of the significance of the evidence
`
`including material facts” is completely absent from the Petition.
`
`20
`
`
`
`
`
`The regulations relating to requirements for petitions provide further detail as
`
`to the nature of the burden on the Petitioner to explain the significance of the
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`evidence. The Petition must include:
`
`(5) The exhibit number of the supporting evidence relied upon to
`
`support the challenge and the relevance of the evidence to the challenge
`
`raised, including identifying specific portions of the evidence that
`
`support the challenge. The Board may exclude or give no weight to the
`
`evidence where a party has failed to state its relevance or to identify
`
`specific portions of the evidence that support the challenge.
`
`37 C.F.R. § 42.104 (emphasis added). Here, the Petitioner merely refers generally to
`
`fourteen paragraphs of the Rodermund Declaration, Ex. 1004, without identifying
`
`either a specific portion, i.e., a specific paragraph, or any particular factual statement
`
`in the Rodermund Declaration. See Pet. 10.
`
`The Petition thus utterly lacks the required “detailed explanation of the
`
`significance of the evidence including material facts,” required by 37 C.F.R.
`
`42.22(a), in support of Petitioner’s burden to show that TR25.835 constitutes prior
`
`art under 35 U.S.C. §102(a) or 102(b). Rather, the Petition merely alleges that the
`
`document was available on a file server as of a certain date. Pet. 9. Petitioner
`
`provides neither a recitation of an applicable legal standard, nor an analysis of how
`
`the availability of the document on a file server might satisfy that applicable legal
`
`21
`
`
`
`
`standard. Thus, the Petition, on its face, fails to meet the requirements of 37 C.F.R.
`
`IPR2020-00224
`U.S. Patent No. 7,075,917
`
`42.22(a).
`
`The Petition similarly fails to meet the requirements of 37 C.F.R. §42.104, as
`
`the Petition fails to identify the specific portions of the Rodermund Declaration that
`
`allegedly support Petitioner’s contention that TR25.835 constitutes prior art. The
`
`Petition merely points generally to Paragraphs 12-24 and 25 of the Rodermund
`
`Declaration, not to specific portions of the Declaration. Pet. 10. In accordance with
`
`37 C.F.R. §42.104, as the Petition fails to identify the specific portions of the
`
`evidence that support Petitioner’s contention that TR25.835 constitutes prior art, the
`
`Board should “exclude or give no weight to” the Rodermund Declaration, and thus
`
`the Petitioner has failed to demonstrate that TR25.835 constitutes prior art.
`
`The Court of Appeals for the Federal Circuit, like the applicable regulations,
`
`stresses the importance of the requirement that the Petition identify the particular
`
`portions of the evidence that support the Petition’s contentions, and explain the
`
`significance of that evidence:
`
`It is of the utmost importance that petitioners in the IPR proceedings
`
`adhere to the requirement that
