`INTRODUCTION
`
`MediaTek Inc. (“MediaTek’”) and NXP USA,Inc. (“NXP”), (collectively,
`
`“Petitioners’’) petitions for Inter Partes Review (“IPR”) of claims 1-4 and 9-12 (“the
`
`Challenged Claims”) of U.S. Patent 8,416,862 (“the ’862 patent”). The ’862 patent
`
`describes wirelessly “feeding back transmitter beamforming information” from a
`
`receiving device to a transmitting device. EX1001, Abstract. But the device claimed
`
`wasjust a conventional variation of typical devices as of the alleged priority date.

`
`SUMMARYOF THE ’862 PATENT
`
`A.
`
`Background
`
`The ’862 patent explains a typical “transceiver(i.e., receiver and transmitter)”
`
`for a wireless communication device was “coupled to the antenna” and included a
`
`low noise amplifier, and intermediate frequency,filtering, and data recovery stages.
`
`EX1001, 1:60-67; 2:1-10 (conventional conversion of “the amplified RF signal into
`
`baseband signals”). The °862 patent acknowledges transceivers traditionally
`
`incorporated beamforming: “a processing technique to create a focused antenna
`
`beam by shifting a signal in timeor in phaseto provide gain of the signal in a desired
`
`direction and to attenuate the signal in other directions.” J/d., 2:66-3:4. The ’862
`
`patent explains “[i]n order for a transmitter to properly implement beamforming(i.e.,
`
`determine the beamforming matrix [V]), it needs to know properties of the channel
`
`over which the wireless communication is conveyed,” necessitating receiver-
`
`provided feedback information so the transmitter can determine the properties. /d.,
`
`3:14-19; EX1003, 928. The receiver sends feedback to the transmitter by
`
`“determin[ing] a channel response (H)” and providingit as “feedback information.”
`
`EX1001, 3:19-22; EX1003, 928. This resulted in feedback data packs “‘so largethat,
`
`during the time it takes to send it to the transmitter, the response of the channel has
`
`7
`
`
`
`Petition for /nter Partes Review
`US. Patent 8,416,862
`
`changed.” EX1001, 3:22-25. To reduce feedback size, conventional receivers
`
`“decompose[d] the channel using singular value decomposition (“SVD”) and sen|t]
`
`information relating only to a calculated value of the transmitter’s beamforming
`
`matrix (V) as the feedback information.” Jd., 3:26-30; EX1003, 428. To reduce
`
`feedback size, conventional receivers calculated matrix V based on H=UDV*,!
`
`where H is channel response matrix, D is diagonal matrix, and U is receiver unitary
`
`matrix, and only send information about matrix V. EX1001, 3:30-33; EX1003, 428.
`
`Per the ’862 patent, “[w]hile this approach reducesthe size of the feedback
`
`information,its size is still an issue for a MIMO wireless communication.” J/d., 3:33-
`
`35. The ’862 patent alleged “a need” “for reducing beamforming feedback
`
`information for wireless communications”(3:49-51), but this allegation ignored the
`
`state of the art. EX1003, 428.
`
`B._Brief Description
`
`The ’862 patent describes a wireless communication system including base
`
`stations, wireless communication devices, and network hardware. EX1001, FIG. 1,
`
`! While each of matrices H, U, D (also called £), and V were referred to by various
`
`terminology in the art and the 862 patent, a POSITA would have understood each
`
`to identify the same respective matrix in this equation. EX1003, 953-56.
`

`
`
`
`Petition for /nter Partes Review
`US. Patent 8,416,862
`
`4:24-27. Base stations are coupled to network hardware to connect to other devices.
`
`Id., 4:46-52. Each base station has antenna(s) for communicating with wireless
`
`communication devices. Id., 4:52-55.
`
`The wireless communication device can include a host device and a radio. Jd.,
`
`FIG.3, 7:21-27. The host device includesa radio interface for sending and receiving
`
`data. /d., ’7:28-30. The interface provides received data to a processing module and
`
`provides processed data from the processing module to the radio for transmission.
`
`Id., 7:36-40, 7:43-44.
`
`Figure 3 showsa radio with “baseband processing module 100, memory 65,
`
`a plurality of radio frequency (RF) transmitters 106-110, a transmit/receive (T/R)
`
`module 114, a plurality of antennas 81-85, [and] a plurality of RF receivers 118-
`
`120.” Id., 7:51-56. The baseband processing module and operational instructions in
`
`memory 65 execute digital
`
`receiver/transmitter
`
`functions,
`
`including “digital
`
`intermediate frequency to baseband conversion.” /d., 7:56-64.
`
`The baseband processing module includes “processing devices,” which “may
`
`be a microprocessor, micro-controller,
`
`... digital circuitry,” etc. Jd., 8:1-9.
`
`In
`
`operation, in receive mode, “baseband processing module 100, based on the mode
`
`selection signal 102 produces one or more outbound symbol streams 104 from the
`
`outbound data 94.” Jd., 8:46-48. It “converts the inbound symbolstreams 124 into
`
`inbound data 92, which is provided to the host device 18-32.” Jd., 9:9-12.

`
`
`

`US. Patent 8,416,862
`
`The method of Figure 7 “addresses the feedback of observed transmitter
`
`beamforming information from a receiving wireless communication device to a
`
`transmitting wireless communication device.” Jd., 13:25-32; FIG. 7. The patent
`
`admits Figure 7’s steps are “typically performed by a baseband processing module”
`
`of a receiving wireless device. Jd., 13:25-35; FIG.7.
`
`That method includes conventional steps, including receiving a preamble,
`
`estimating a channel response H at the receiver, and estimating the transmitter
`
`beamforming matrix V based on the channel response H and receiver beamforming
`
`unitary matrix U. Id., 13:36-47. The ’862 patent explains “channel response (H),
`
`estimated transmitter beamforming unitary matrix (V), and the known receiver
`
`beamforming unitary matrix (U) are related” by well-known singular value
`
`decomposition (SVD) equation: “H=UDV*, where, D is a diagonal matrix,” to
`
`determine estimated transmitter beamforming unitary matrix (V).
`
`/d., 13:47-53;
`
`EX1003, 49/28, 39, 53.
`
`To purportedly reduce beamforming feedback information, the ’862 patent
`
`proposed a known “solution”—decomposingthe estimated transmitter beamforming
`
`unitary matrix (V) using a “Givens Rotation.” J/d., 13:58-67; EX1003, 939.
`
`It
`
`explains “the coefficients of the Givens Rotation and the phase matrix coefficients
`
`serve as the transmitter beamforming information that is sent from” receiver to
`
`transmitter. EX1001, 15:34-38.
`
`In particular,
`
`the transmitter beamforming
`
`10
`
`
`
`Petition for /nter Partes Review
`US. Patent 8,416,862
`
`information is the product of the Givens Rotation (“the set of angles ... are
`
`reduced”). Id., 13:63-14:3; see also 14:34-36; EX1003, 439. Using these techniques,
`
`“the feedback of transmitter beamforming information” requires less data.
`
`J/d.,
`
`15:59-61. But, as explained in Grounds 1-5, these solutions were in prior art
`
`publications.
`
`C.
`
`Critical Date
`
`The ’862 patent issued on April 9, 2013, from Application No. 11/237,341
`
`(“341 application”), filed September 28, 2005. EX1001, cover. It is a continuation-
`
`in-part of Application No. 11/168,793 (“793 application”, EX1014), filed June 28,
`
`2005, and claims priority to Provisional Application Nos. 60/673,451 (451
`
`provisional”, EX1010), filed April 21, 2005, and 60/698,686 (“686 provisional”,
`
`EX1011),filed July 13, 2005.
`
`The claims require at least one feature never contemplated in the °451
`
`provisional or *793 application. EX1003, 4948-50. Independentclaim 9 recites “a
`
`baseband processing module operable to: ... decompose the estimated transmitter
`
`beamforming unitary matrix (V)...” EX1001, 17:20, 17:28-30. Neither the °451
`
`provisional nor ’793 application disclose decomposing matrix V. EX1003, 449; see,
`
`generally EX1010, EX1014. Therefore, the earliest possible priority date of the
`
`642 patent is the filing date of the ’686 provisional—July 13, 2005 (the “Critical
`
`Date’”’)—-which addresses decomposing matrix V. EX1003, 950; EX1011, 22:3-5.
