`
`SUMMARY OF OUT-OF-SCOPE QUESTIONS
`FROM DR. MITZENMACHER’S DEPOSITION1
`
`Subject Matter
`
`Questions regarding whether it is theoretically possible to derive
`a systematic generator matrix from any parity-check matrix, and
`whether a person of ordinary skill in the art (“POSA”) could
`have done so.
`
`Questions regarding how one might implement an encoder for
`any given parity-check matrix, and Dr. Mitzenmacher’s
`experience implementing encoders in software or hardware.

`
`Questions regarding Exhibit 1044, 2 a new exhibit created by
`Petitioner’s counsel and not disclosed until Dr. Mitzenmacher’s
`deposition, purportedly depicting a Tanner graph of a code.
`Exhibit 1044 is labeled “Tanner graph for a code described by
`Fig. 2 of the ’710 Patent.” Questions include comparisons of
`Exhibit 1044 with Figure 3 of the ’710 Patent, and whether
`Exhibit 1044 is within the scope of Claim 1 of the ’710 Patent.
`
`
`
`1 Exhibit 1062 in IPR2017-00210, which corresponds with Exhibit 1262 in
`
`IPR2017-00219, Exhibit 1045 in IPR2017-00297) and Exhibit 2038 in IPR2017-
`
`00700, -00701, and -00728.

`
`IPR2017-00210. Exhibit 1044 was also submitted as Exhibit 1244 in IPR2017-

`
`Questions regarding newly proposed modifications to Divsalar
`and whether such modifications would meet the limitations of
`Claim 1 of the ’710 patent. Specifically, the questioning in the
`cited sections relate to new modifications to Divsalar: (1) where
`a regular repeat-Q is modified to repeat some bits Q times and
`other bits Q+1 times, (2) where a regular repeat-Q is modified to
`repeat some bits Q times and other bits Q+10 times, (3) where a
`regular repeat-3 is modified to repeat some bits 3 times and
`other bits 4 times.
`
`156:12-162:8;
`163:12-168:8
`
`Questions regarding modifications to a Tanner graph found in
`Khandekar’s thesis and whether they meet the limitations of
`Claim 1 of the ’710 patent. The Board has rejected Khandekar’s
`thesis as prior art.
`
`181:3-192:10; Questions regarding how a POSA would implement Divsalar’s
`accumulator in hardware, as well as questions regarding the
`simplicity of Exhibit 1045, an exhibit created by Apple’s
`counsel and first shown at Dr. Divsalar’s deposition. Exhibit
`1045 purports to be a circuit diagram for an accumulator
`consisting of a single XOR gate and a single bit flip-flop.3
