`“storage module”

`“a module that stores non-negligible
`amounts of energy from an input
`electromagnetic signal”
`
`•
`
`“non-negligible” means
`“distinguishable from noise”
`• successful down-conversion is
`proof of non-negligible energy

`system that stores non-negligible

`

`The inventors defined “storage module”
`
`FIG. 82A illustrates an exemplary energy transfer system 8202 for down-
`converting an input EM signal 8204. The energy transfer system 8202 includes
`a switching module 8206 and a storage module illustrated as a storage
`capacitance 8208. The terms storage module and storage capacitance, as used
`herein, are distinguishable from the terms holding module and holding
`capacitance, respectively. Holding modules and holding capacitances, as used
`above, identify systems that store negligible amounts of energy from an under-
`sampled input EM signal with the intent of "holding" a voltage value. Storage
`modules and storage capacitances, on the other hand, refer to systems
`that store non-negligible amounts of energy from an input EM signal.

`

`“non-negligible” means “distinguishable from noise”
`
` The Middle District of Florida adopted
`ParkerVision’s own proposed construction
`that non-negligible energy is
`“distinguishable from noise.” ParkerVision,
`Inc. v. Qualcomm Inc., 2013 WL 633077, at
`*5-*7 (M.D. Fla. Feb. 20, 2013)
`
` “That construction is not disputed on
`appeal.” ParkerVision, Inc. v. Qualcomm
`Inc., 621 F. App’x 1009, 1018 (Fed. Cir. 2015)
`
`DEMONSTRATIVE EXHIBIT - NOT EVIDENCE

`
`TCL & Hisense
`Ex. 1022
`
`

`

`Successful down-conversion is “proof”
` Sorrells: “transferring a non-negligible
`amount of energy” means “you have to
`transfer enough energy to overcome
`the noise in the system to be able to
`meet your specifications.” 621 F. App’x
`at 1019.
`
` If “a circuit successfully down-
`converts, that is proof that enough
`energy is transferred to overcome the
`noise in the system.” 621 F. App’x at
`1019.

`
`

`

`Two issues resolved by operation of collateral estoppel
`
`“non-negligible” means “distinguishable from noise”
`successful down-conversion is proof of non-negligible energy
`
`Importantly, our precedent makes clear that collateral
`estoppel is not limited to patent claims that are identical.
`Rather it is the identity of the issues that were litigated
`that determines whether collateral estoppel should apply.
`
`Nestle USA, Inc. v. Steuben Foods, Inc., 884 F.3d 1350, 1352 (Fed. Cir. 2008)
`
`DEMONSTRATIVE EXHIBIT - NOT EVIDENCE
`
`15
`
`TCL & Hisense
`Ex. 1022
`
`

`

`Attempts to avoid collateral estoppel fall short
` Sorrells testified “years after the patent issued” (Sur-Reply at 8)
` Sorrells is just “one of five ’835 patent inventors” (Id. at 9)
` Sorrells tried “to prove infringement at trial” in Qualcomm (Id. at 10
`n.11).
` Sorrells testified only as to “one of the 19 accused products” in
`Qualcomm (Id.)
` Sorrells also mentioned “cellular/cellphone specifications” (Id. at 11-
`13)
` Sorrells method is “one way (not the only way)” (Id. at 12).

`Anything above 0.10% is “non-negligible”
`
`1. A method for down-converting a carrier signal to a lower frequency signal, comprising the steps
`of:
`(1) receiving a carrier signal;
`(2) transferring non-negligible amounts of energy from the carrier signal, …
`
`41. The method according to claim 1, wherein step (2) comprises the steps of:
`(a) transferring a non-negligible portion of energy contained in a portion of the carrier signal …
`
`42. The method according to claim 41, wherein step (2)(a) comprises the step of transferring at
`least one tenth of one percent of the energy contained in a half period of the carrier signal.

`Hulkko’s capacitors are “storage modules”
` In the underlying litigation, ParkerVision alleges that “capacitors”
`constitute “storage modules”
`• “a module having one or more capacitors” (Ex. 2002 ¶¶ 114-115)
` Store “non-negligible” energy under Fed. Cir.’s Qualcomm opinion
` 0.5% of “available energy” as “calculated” by ParkerVision’s own
`expert is “non-negligible”; see ’551 patent claim 42:
`• “at least one tenth of one percent [0.10%] of the energy contained in a half
`period of the carrier signal” is a “non-negligible” amount of energy

`The Board rejected ParkerVision’s “very weak” evidence
`
` IPR2020-01265 FWD: “neither Patent Owner nor Dr. Steer makes any
`attempt to establish nexus” with the claims. Ex. 2037 at 64.
` IPR2020-01265 FWD: ParkerVision’s evidence “is very weak.” Id. at 65.
` Dr. Steer admittedly makes “essentially the same” arguments as he made in
`IPR2020-01265. See Ex. 1016 at 135:17-136:14.
