`
`CAUTION: External email. Please do not respond to or click on links/attachments unless you recognize the sender.
`
`Philip,
`
`This is the exact issue that was discussed at the December 19 Pretrial Conference. You
`speci(cid:84)cally said to the Court “[i]t's called background art, but it looks a lot like invalidity, and
`that's exactly why we think it's confusing.” Charter responded by explaining “the importance
`of this, Your Honor, is that the Plaintiff is going to claim to have solved a problem that had not
`been solved, and that's what they contend is the value proposition of their invention. It goes
`to damages.” The Court sided with Charter and denied Touchstream’s MIL No. 3. See
`December 19, 2024, Tr. at 74:9-79:22; see also Dkt. 275 at 2 (“Plaintiff’s MIL No. 3 … This
`motion in limine is DENIED as overbroad. Defendants are bound by their representations
`that they will not use unelected prior art to show the jury that the prior art meets the
`limitations of a claim.”) (emphasis in original).
`
`This exact issue has already been briefed, and Touchstream lost. As we explained at the
`pretrial conference and in the email below, Charter will not use these trial exhibits to argue
`invalidity, but they are nonetheless relevant to other issues, such as damages. Contrary to
`your allegation, Charter is not using these references to “backdoor[] invalidity arguments”
`into the case.

`Finally, your case, Mojo v. Samsung, is not on point. The Court gave Samsung the same
`instruction that it gave Charter regarding not comparing unelected prior art references to the
`claim limitations of the asserted patents, but did not strike the use of those references in toto,
`speci(cid:84)cally explaining that there are permissible uses of the unelected references. See Mojo
`v. Samsung, Case No. 2:22-cv-00398-JRG-RSP, Dkt. 251 at 8-9 (July 23, 2024 E.D. Tex.).
`
`If necessary, we are available to discuss on Friday, February 21 at noon ET.

`Subject: Re: Touchstream v. Charter | Joint Exhibit List
`
`Thanks, Carson. We disagree that is what the Court said at the December 19 pretrial
`conference, or that the Court "speci(cid:84)cally sanctioned" the use of these references in this
`manner. At any rate, neither the Court nor Touchstream could have considered this issue at
`that pretrial conference, as that hearing occurred before Charter narrowed its invalidity
`theories on January 6.

`sections at §§ VII-VIII, IX-XII. Both are problematic—the background art was raised with the
`Court, which, as noted below, restricted their use to those references you actually elect in a
`prior art combination. 12/19/24 Pretrial Conf. Tr. 79:14-15 ("That showing should be limited
`to the elected prior art."). And your citations to § XIII of Dr. Shamos's report, which just refers
`back to the invalidity sections of his report, show that the use of these exhibits must rely on
`unelected invalidity opinions at trial.
`
`Using these references as exhibits is improper where you have not elected to use them in a
`prior art combination, and will confuse the jury. Your proposed use for damages purposes
`simply backdoors invalidity arguments without the legal standard of proving invalidity on a
`limitation by limitation basis and by clear and convincing evidence.
`
`I'm attaching more authority on the subject, at 7-9. We would like to avoid burdening the
`Court with this, but if we are truly at an impasse we intend to seek relief soon. If you are not
`prepared to remove these exhibits from the exhibit list, please let us know some times this
`week that your team is available to discuss and hopefully avoid motion practice.

`Subject: Re: Touchstream v. Charter | Joint Exhibit List
`
`External E-mail
`
`Counsel,
`
`It's our understanding that Charter is not currently prepared to make any changes to the parties' joint
`exhibit list. Given Charter's narrowed invalidity theories, the exhibits listed in Phil's email below re(cid:85)ect
`prior art that is no longer relevant to any claim or defense. As such, they are only potentially relevant
`as background references. It's our position that these exhibits are excluded under the Court's
`standing MIL No. 4. Further, Charter counsel agreed to limit the use of unelected prior art to just
`background at the pretrial conference on December 19, 2024 (see Tr. pp. 77-79). Based on our
`understanding of Judge Payne's prior rulings (in this and other cases), background art references are
`not exhibits and should not go back to the jury.
`
`Please let us know Charter's rationale for keeping unelected prior art references on the JTX list.
`
`Thanks,
`Anita
