`The method of claim 12, further comprising storing a default window
`size for monitoring for system information transmissions.
`Claim 15
`15
`The method of claim 14, further comprising monitoring for system
`information transmissions based on a specified window size indicated

`channel of a wireless communication network configured for operation
`in accordance with 3GPP E-UTRA standards,
`
`24[a]
`
`24[b]
`

`
`each time window spanning a plurality of subframes, and each time
`window being a predetermined time interval in one or more
`corresponding frames;
`
`24[d]
`

`
`24[e] wherein the selecting is such that subframes carrying the dynamic part
`of the system information for a first time window begin at a first
`subframe for a first frame, and the subframes carrying the dynamic part
`of the system information for a second time window begin at a second
`subframe in a second frame, where the first and second subframes have
`different subframe indexes relative to their corresponding frame;
`
`24[f]
`
`including an indicator in each of the selected subframes to indicate to
`receiving user equipment that the subframe carries system information.

`
`
` THE ’357 PATENT
` Brief Description
`The ’357 patent relates to “the transmission of system information to user
`
`equipment (UE)...by radio base stations in a wireless communication network
`
`configured according to 3GPP E-UTRA...standards, also referred to as 3GPP
`
`LTE.”1 SAMSUNG-1001, 1:7-14. The ’357 patent acknowledges that, in LTE,
`
`the dynamic part of the system information can be transmitted using the Downlink
`
`Shared Channel (DL-SCH) and should be repeated regularly. SAMSUNG-1001,
`
`2:9-35; SAMSUNG-1003, ¶28. In LTE, the dynamic part of the system
`
`information is divided into “scheduling units [(SU)], also referred to as System
`
`Information Messages.” SAMSUNG-1001, 2:25-27.
`
`The ’357 patent describes transmitting system information with specific
`
`RNTIs (Radio Network Temporary Identifiers) indicating the presence of system
`
`information in a subframe. SAMSUNG-1001, 2:39-47; SAMSUNG-1003, ¶29.
`
`The ’357 patent acknowledges that, in LTE, “Layer 1/Layer 2 (Ll/L2)
`
`
`1 The term “LTE” is used in reference to the patent and prior-art disclosures as of
`
`the Critical Date, and no comment is being made as to the applicability of a
`
`particular technology or feature to the current LTE standard.

`IPR of U.S. Patent No. 8,995,357
`
`
`control signaling, also known as the Physical Downlink Control Channel
`
`(PDCCH), is transmitted at the beginning of each subframe...to inform a UE about
`
`various items” and “includes the RNTI...associated with the UE for which the DL-
`
`SCH carries data in the given subframe.” SAMSUNG-1001, 1:32-41;
`
`SAMSUNG-1003, ¶30.
`
`In the ’357 patent, “the transmission of system information is carried out
`
`similar to the transmission of user data on DL-SCH” according to the LTE
`
`standard, but “[i]nstead of using an RNTI of a specific UE..., a specific System-
`
`Information RNTI (SI-RNTI), indicating that system information to be read by all
`
`UEs...is being transmitted, is included in the corresponding L1/L2 control
`
`signaling.” SAMSUNG-1001, 4:14-18; SAMSUNG-1003, ¶31.
`
`
`Summary of the Prosecution History
`To distinguish the claims from R2-072205 during prosecution, applicant
`
`argued that “SUs are not ‘time windows’,” but rather “one of skill in the art would
`
`understand that a subframe might be considered a time window (generically), or a
`
`collection of subframes (e.g., a frame) might be considered a time window.”
`
`SAMSUNG-1002, 102, 145. Applicant also distinguished the claimed indicator
`
`from R2-072205’s value tag, arguing that “Value tags are carried on the BCH, ‘in a
`
`System Information Block called the Master Information Block (MIB),’” not “in
`
`each relevant subframe,” and that R2-072205’s “‘value tag’…is not ‘an indication

`
`
`
`
`Attorney Docket No. 39843-0096IP1
`IPR of U.S. Patent No. 8,995,357
`
`
`of the presence of system information.’” SAMSUNG-1002, 106, 150, 153, 192-
`
`194, 197, 232-233, 235; SAMSUNG-1003, ¶¶32-33.
`
`The examiner issued a notice of allowance after applicant amended claims to
`
`include “wherein the wireless communication network is configured for operation
`
`in accordance with 3GPP E-UTRA standards and wherein the indicator is a System
`
`information Radio Network Temporary Identifier (SI-RNTI).” SAMSUNG-1002,
`
`34-32, 24-30. The examiner stated, as the reasons for allowance: “the prior
`
`art…fails to teach…‘transmitting system information on a downlink shared
`
`channel in recurring time windows, each time window spanning a plurality of
`
`subframes; including an indicator to indicate to receiving user equipment that the
`
`subframe carries system information and wherein the indicator is a [SI-RNTI].’”
`
`SAMSUNG-1002, 29; SAMSUNG-1003, ¶¶34-35.
`
` Level of Ordinary Skill in the Art
`For purposes of this IPR, Petitioner submits that a person of ordinary skill in
`
`the art at the time of the alleged invention (a “POSITA”) would have had a
`
`Bachelor’s degree in electrical engineering, computer engineering, computer
`
`science, or a related field, and 3-5 years of experience in the design or
`
`development of wireless communication systems, or the equivalent. SAMSUNG-
`
`1003, ¶24. Additional graduate education could substitute for professional
`
`experience, or significant experience in the field could substitute for formal
`

`
`

`

`
`
`education. Id.

`
`
` Claim Construction
`Based on the evidence below, striking similarities between the prior art’s
`
`description of the claimed elements and that found within the ’357 patent
`
`specification, and the well-established principal that “claim terms need only be
`
`construed to the extent necessary to resolve the controversy,” no formal claim
`
`constructions are necessary in this proceeding. Wellman, Inc. v. Eastman Chem.
`
`Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011).
`
`Petitioner reserves the right to respond to any constructions offered/adopted
`
`by Patent Owner/Board. Furthermore, Petitioner is not conceding that each
`
`challenged claim satisfies all statutory requirements, and is not waiving any
`
`arguments concerning grounds that can only be raised in district court.
`
` THE CHALLENGED CLAIMS ARE UNPATENTABLE
` GROUND 1A: Claims 1-2, 9-10, 22, and 24 are obvious
`based on Lee-746, Lee-668, and R2-072183
`1. Overview of Lee-746
`Lee-746 describes “a method of transmitting/receiving LTE system
`
`information in a wireless communication system.” SAMSUNG-1004, [0002]. In
`
`Lee-746, “the system information may be grouped in primary system information
`
`and secondary system information.” SAMSUNG-1004, [0038]. “The secondary
`
`system information may be transmitted on a transport channel with flexible

`
`
`scheduling, such as DL-SCH.” SAMSUNG-1004, [0039], [0044], [0047];
`
`SAMSUNG-1003, ¶¶36-37.
`
`“The system information may be organized in SIBs (system information
`
`blocks), a MIB (Master information block) and scheduling blocks.” SAMSUNG-
`
`1004, [0027]. “The MIB...may give or provide timing information of the
`
`scheduling blocks and the different SIBs.” Id. An “eNB can schedule SIBs (i.e.,
`
`SIBs on SCH) within a specific Transmission Time Intervals (TTI) indicated by
`
`the MIB,” and “control information of the TTI may indicate existence of a SIB in
`
`the TTI and may schedule a time or frequency of the SIB.” SAMSUNG-1004,
`
`[0043]; SAMSUNG-1003, ¶¶38-39.
