`II. THE ’943 PATENT
`A.
`Summary
`The ’943 patent describes “Internet Protocol (IP) based wireless data trans-
`
`missions” that “are simultaneously provided between a wireless device and a
`
`server.” EX-1001, Abstract; EX-1003, ¶¶45-46. Referring to Figure 10, the wire-
`
`less device is equipped with “T/R units 1008, 1010, and 1012” that process “data
`
`streams 1002, 1004, and 1006.” EX-1001, 3:26-27, 7:26-8:41. In the ’943 patent,
`
`“[e]ach subtask being processed can be assigned to a separate channel.” Id., 7:38-
`
`39. Once processed, “data streams may be interfaced separately with server C
`
`
`scope or grounds that can only be raised in district court. For this petition, Peti-
`
`tioner applies prior art in a manner consistent with Patent Owner’s allegations of
`
`infringement before the district court.

`Prosecution History
`The claims were allowed after two RCEs. EX-1002, 9-254. Rejections were
`
`overcome by amendment to recite “wherein one or more subtasks are assigned to
`
`one or more channels, and the one or more channels are sampled and clocked indi-
`
`vidually.” Id., 69-151; EX-1003, ¶¶47-49.

`telephone (CCT).” EX-1008, 1:30-33, 2:42-46. Byrne’s CCT utilizes “CT-2 or
`
`DECT” which are digital cordless systems, and GSM or DCS which are digital cel-
`
`lular systems. Id., 7:19-24, 1:41-44, 5:20-33, 10:52-12:57, 8:16-38; EX-1003, ¶50.
`
`Referring to Figure 2, Byrne’s CCT includes cellular transceiver 230 and an-
`
`tenna 238 for cellular communication, and cordless transceiver 220 and antenna
`
`228 for cordless communication. EX-1008, 7:25-32; EX-1003, ¶51. Byrne’s CCT
`
`further includes microprocessor 210 “for controlling the CCT 200 as a cordless tel-
`
`ephone, a cellular telephone or a cellular cordless telephone.” Id., 7:56-8:2. In
`
`Byrne, “both cellular and cordless operations are in progress at the same time.”
`
`Id., 8:6-9. Byrne’s CCT can “automatically select and reselect which of the availa-
`
`ble radio systems to use.” EX-1008, 3:19-4:21, 5:34-6:18, 10:2-51; EX-1003, ¶52.

`
`Analysis
`
`Claim 1
`
`1[pre]:
`To the extent the preamble is limiting, Byrne’s “cellular cordless telephone
`
`(CCT)” (wireless communication device) “may be a mobile unit installed in a ve-
`
`hicle, a so called transportable unit or a hand held portable unit.” EX-1008, 7:11-
`
`13; EX-1003, ¶69.
`
`1[a]:
`
`Byrne’s CCT includes “an antenna 228 for cordless communication and an
`
`antenna 238 for cellular communication,” and thus includes a plurality of anten-
`
`nas. EX-1008, 7:13-15; EX-1003, ¶70.
`
`1[b]:
`
`Referring to Figure 2, Byrne’s CCT includes cordless transceiver 220 in-
`
`cluding cordless receiver 221 and cordless transmitter 222, and cellular transceiver
`
`230 including cellular receiver 231 and cellular transmitter 232. EX-1008, 7:26-
`
`32. The CCT further includes microprocessor 210 (processor) “for controlling the
`
`CCT 200 as a cordless telephone, a cellular telephone or a cellular cordless tele-
`
`phone.” Id. 7:26-32, 7:56-8:28; EX-1003, ¶71.

`
`
`
`A POSITA would have understood that cordless and cellular transceivers
`
`220, 230 and microprocessor 210 together constitute (or are part of) a communica-
`
`tion component coupled to the plurality of antennas (e.g., antennas 228, 238).
`
`EX-1003, ¶72.
`
`1[c]:
`
`The communication component (1[b]) in Byrne’s telephone operates on
`
`various cordless protocols and frequency bands (a first frequency band using a
`
`wireless communication protocol), as well as various cellular protocols and fre-
`
`quency bands (alternatively, a first frequency band using a wireless communica-
`
`tion protocol). EX-1003, ¶73. For example, Byrne’s “cordless telephone systems
`
`7
`
`

`

`Attorney Docket No. 39843-0128IP1
`IPR of U.S. Patent No. 9,614,943
`operate in frequency bands at 49 MHz (CTØ), 860 MHz (CT2) and 1880-1900
`
`MHz (DECT) and cellular telephone systems in frequency bands 890-905 MHz
`
`and 935-950 MHz (TACS), 905-915 MHz and 950-960 MHz (GSM) or 1800 MHz
`
`(DCS).” EX-1008, 7:19-24; EX-1003, ¶73.
`
`1[d]:
`
`Byrne teaches subtasks and channels in a way that aligns with the ’943 pa-
`
`tent’s limited disclosure. EX-1003, ¶77; EX-1001, 7:1-8:41, Figures 9-12. In the
`
`’943 patent, multiple channels are provided for parallel communications and pro-
`
`cessing of wireless data streams between two wireless units. EX-1001, 7:1-25.
`
`Multiple data streams are separately processed using multiple transceiver units.
`
`Id., 7:26-52, Figure 10; 7:53-8:16, Figure 11. Notably, the ’943 patent describes
`
`“[e]ach subtask being processed can be assigned to a separate channel.” Id., 7:38-
`
`39, 7:66-67. As described below, Byrne describes two different channels (e.g.,
`
`cordless and cellular channels) as two separate communication pathways for two
`
`different data streams that are processed separately, just like the ’943 patent. EX-
`
`1003, ¶77. With this structure, and consistent with the ’943 patent, Byrne includes
`
`a first input/output communication channel dedicated for cellular telephony (a first
`
`subtask), and a second input/output communication channel dedicated to cordless
`
`telephony (a second subtask). EX-1003, ¶77.
`
`Specifically, Byrne’s telephone communicates using “cordless audio channel
`
`8
`
`

`

`Attorney Docket No. 39843-0128IP1
`IPR of U.S. Patent No. 9,614,943
`240” and “cellular audio channel 250.” EX-1008, 8:39-43, 6:36-8:38; EX-1003,
`
`¶74. Byrne assigns a cordless telephony subtask to the cordless channel and a cel-
`
`lular telephony subtask to the cellular channel. EX-1003, ¶75. Referring to Figure
`
`2, Byrne describes that subtasks for cordless communication, such as receiving “in-
`
`coming [cordless] calls (ringing),” receiving “security codes and broadcast infor-
`
`mation relevant to the cordless system,” and “sending dialling information” for
`
`cordless transmissions, are assigned to the cordless channel. EX-1008, 8:16-28,
`
`8:39-43. These operations are subtasks assigned to the cordless channel. EX-
`
`1003, ¶75. Similarly, Byrne describes that subtasks for cellular communication,
`
`such as performing the “signalling protocols … used in the cellular system,” are
`
`assigned to the cellular channel. EX-1003, ¶76; EX-1008, 8:29-43. Through these
`
`communication operations, Byrne’s CTT renders obvious assignment of subtasks
`
`to each of the cordless and cellular channels. EX-1003, ¶76; EX-1042, 1:55-2:8
`
`(“subtasks … perform a discrete communication function in the wireless communi-
`
`cation system”); EX-1043, 1:34-2:50 (“Sub-tasks associated with call processing”);
`
`EX-1044, 4:23-5:59 (“[r]adio resources entity 214 performs a plurality of functions
`
`specified by GSM specifications” with responsibilities “divided into a number of
`
`subtasks”).

`
`
`
`Additionally, a POSITA would have found it obvious that Byrne’s cordless
`
`and cellular radio channels are sampled and clocked individually according to dif-
`
`ferent specifications required in the respective protocols. EX-1003, ¶78. Indeed,
`
`certain factors (e.g., sampling rates, processor clock rates, information data rates,
`
`computational requirements) vary for different wireless systems such that a
`
`POSITA would have recognized and/or found obvious that Byrne’s cordless and
`
`cellular channels require or at least would benefit from separate and individual
`
`sampling and clocking. Id.

`Sampling refers to the process of capturing samples of a continuous signal
`
`transmitted over a wireless channel. EX-1020, 4-5. It was well-known that, to re-
`
`construct the original signal from a set of discrete samples, or to capture discrete
`
`samples of a continuous signal without loss of information, the rate of sampling
`
`needs to be at least twice the bandwidth of the signal, which is called the Nyquist
`
`rate. EX-1020, 10. Further, it was known that many receivers sample the signal at
`
`a higher rate than the Nyquist rate depending on the type of processing that needs
`
`to be performed on the sampled signals. EX-1003, ¶79; EX-1024, 10; EX-1026, 6;
`
`EX-1030.
`
`For example, the DECT protocol uses 10 frequency channels, each with a
`
`bandwidth of 1.728 MHz. EX-1039, 3 (Table 2.0); EX-1036, 3:4-7. Therefore, a
`
`receiver needs to sample the signal communicated over the DECT channel with a
`
`rate of over 3,456,000 samples/second (i.e., twice 1.728 MHz). EX-1003, ¶80.
`
`The GSM cellular protocol uses 124 frequency channels, each with a bandwidth of
`
`200 kHz. EX-1039, 3 (Table 2.0); EX-1035, 4:14-18. Therefore, a receiver needs
`
`to sample the signal communicated over the GSM channel with a rate of over
`
`400,000 samples/second. EX-1003, ¶80. As such, a POSITA would have recog-
`
`nized and/or found obvious that the DECT and GSM systems, which are examples
`
`of standards used for Byrne’s cordless and cellular channels, are sampled individu-
`
`ally at different rates that accommodate different bandwidths. EX-1003, ¶80; EXs-

`
`1024-1026.
`
`Further, a clock is an electronic component that provides repetitive timing
`
`pulses to a processor (and/or other electronic components in a digital system), en-
`
`suring that computations performed by the processor are synchronized. EX-1003,
`
`¶81; EX-1038, 1, 3, 4, 6; EX-1039, 10, 11, 15. The sampling of a signal at a com-
`
`munication receiver is typically performed by an analog-to-digital converter
`
`(ADC). EX-1039, 4-5, 11-15. A POSITA would have understood that the clock
`
`driving the ADC at a receiver is the same as, or at least derived from, a clock driv-
`
`ing the computational processor, as the samples created by the ADC stream into
`
`and are processed by the processor, and therefore the samples from the ADC
`
`should be synchronized with the computations at the processor. Id.; EX-1003, ¶81.
`
`Additionally, each of the computational instructions performed by the processor
`
`for the samples requires a certain number of clock cycles. EX-1003, ¶81; EX-
`
`1038, 2-4. In wireless systems, processors perform the necessa
