`• Li’s block 405 is a per-cluster
`parameter deciding section.
`• In the combination, block 405
`would decide modulation and
`coding parameters for an
`entire cluster group.
`• As taught by Li, Vijayan, and

`signaling overhead.

`Li Does Not Discourage Using Joint Parameters

`1003).
`• Not in the group-based cluster
`allocation section. Li, 11:46-12:65.
`• While “different clusters can have
`different modulation/coding rates,”
`Li, 8:3-5, different modulation and
`coding rates are not required in Li.

`
`INVT Improperly Relies on Bodily Incorporation
`
`• “The test for obviousness is not whether the features of a
`secondary reference may be bodily incorporated into the
`structure of the primary reference, but rather whether a
`skilled artisan would have been motivated to combine the
`teachings of the prior art references to achieve the claimed
`invention.” Allied Erecting & Dismantling Co. v. Genesis
`Attachments, LLC, 825 F.3d 1373, 1381 (Fed. Cir. 2016).
`• Not necessary to bodily incorporate:
`• Hashem’s creation of subbands comprising acceptable subcarriers.
`• Hashem’s transmission of a bit mask identifying those subcarriers.

`
`Cioffi, Abstract (Ex. 1006)
`
`
`
`The Cioffi Patent
`
`• Cioffi teaches a weighting
`factor to reduce the
`number of information
`bits transmitted in certain
`lower-quality
`subchannels.

`
`
`
`Motivation to Combine Li, Vijayan, Hashem,
`and Cioffi
`• All related to multicarrier systems having dynamic
`modulation and coding based on channel quality.
`• Cioffi states the motivation to use Cioffi’s weighting per
`subchannel for all of the clusters in a cluster group of Li –
`“to take into account factors other than the SNR
`monitored at the receiver.”

`
`
`Cioffi Is Analogous Art
`
`• A POSITA would have had experience with both wired and
`wireless multicarrier communications, including ADSL.
`• OFDM was used in both wireless and ADSL networks
`before the ’439 Patent – common principles for both
`technologies that a POSITA would have been familiar with.
`• Cioffi and the ’439 Patent both weight the number of bits
`to address the same problems – minimizing the impact of
`interference and noise in a multicarrier network.
`• Both use weighting for the same purpose – to build in a
`buffer for sources of interference and noise.

`
`
`
`The Combination Teaches the Claimed
`Weighting Per Subband Group
`• Li teaches that adaptive modulation and coding that may rely on factors
`other than SNR (different subcarrier channel gains caused by multipath).
`• Vijayan teaches deciding the coding parameters such that the number
`of information bits that are able to be assigned to all of the subbands is
`not exceeded.
`• A POSITA would have applied Cioffi’s weighting technique to the cluster
`groups of Li’s system (as modified by Vijayan and Hashem) by assigning
`the same weight to all the clusters in a group, to account for
`interference from neighboring cells.
