`P.R. 4-3 JOINT CLAIM CONSTRUCTION AND PREHEARING STATEMENT
`
`In accordance with Patent Rule 4-3 and the Court’s Docket Control Order of June 3, 2021
`
`(Dkt. No. 34), the parties to the above-captioned case provide the following Joint Claim
`
`Construction and Prehearing Statement regarding the asserted claims of U.S. Patent No. RE47,049
`
`(the “’049 patent”) and U.S. Patent No. RE48,371 (the “’371 patent”). In accordance with Patent
`
`Rule 4-2(c), the parties met and conferred for the purposes of narrowing the issues and finalizing
`
`preparation of this Joint Claim Construction Chart.
`
`I.
`
`P.R. 4-3(a)(1) Agreed Constructions
`
`The Parties’ Agreed-Upon Constructions are attached hereto as Exhibit A.1
`
`II.
`
`P.R. 4-3(a)(2) Disputed Terms
`
`Plaintiff’s proposed constructions and identification of intrinsic and extrinsic evidence is
`
`attached hereto as Exhibit B. Defendants’ proposed constructions and identification of intrinsic
`
`1 Vocalife states that Vocalife agrees to the constructions in Exhibit A for the reasons set forth in
`the Court’s Claim Construction Order in Vocalife LLC v. Amazon.com, Inc., No. 2:19-cv-00123-
`JRG, Dkt. 83.

`Case 2:20-cv-00401-JRG-RSP Document 49 Filed 08/27/21 Page 2 of 5 PageID #: 1304
`
`and extrinsic evidence is attached hereto as Exhibit C. Each party also reserves the right to cite
`
`to intrinsic and/or extrinsic evidence cited by the other party.
`
`III.
`
`P.R. 4-3(a)(3) Anticipated Length of Time for the Claim Construction Hearing
`
`The Parties expect that 3 hours will provide sufficient time to conduct the claim
`
`construction hearing.
`
`IV.
`
`P.R. 4-3(a)(4) Anticipated Witnesses at the Claim Construction Hearing
`
`At the present time, no party proposes to call witnesses for live testimony at the claim
`
`construction hearing
`
`V.
`
`P.R. 4-3(a)(5) Other Issues to be Addressed Prior To the Claim Construction
`
`Hearing
`
`Amazon requests that the Court schedule a prehearing conference for oral argument on
`
`Amazon’s pending Motion to Dismiss First Amended Complaint (Dkt. No. 38). In that Motion,
`
`Amazon requests that the court dismiss this case in its entirety or stay the case pending a decision
`
`in a related Federal Circuit appeal. A decision to stay or dismiss this case could eliminate the need
`
`for any claim construction here. Amazon submitted an unopposed motion for a hearing on the
`
`Motion, but no hearing date has been set. (See Dkt. No. 48.) Amazon proposes that a prehearing
`
`conference, at which oral argument on Amazon’s Motion could be heard, be scheduled for
`
`September 21, 22, 28, or 29, or October 6, 12, or 13, so that the Court may consider whether to
`
`stay or dismiss this case prior to the claim construction hearing currently scheduled for November
`
`19, 2021. Proceeding with claim construction here while the Federal Circuit is considering
`
`overlapping, case-dispositive issues in the pending appeal is not an efficient use of resources for
`
`the Court or the parties.

`
`Vocalife states that it is not presently aware of any issues which might be taken up at a
`
`prehearing conference prior to the Claim Construction Hearing.
`
`VI.
`
`P.R. 4-3(b) Service of Expert Testimony
`
`In accordance with Patent Rule 4-3(b) the parties will each, simultaneous with this filing,
`
`serve a disclosure of expert testimony consistent with Fed. R. Civ. P. 26(a)(2)(B)(i)-(ii) or
`
`26(a)(2)(C) for any expert on which it intends to rely to support its proposed claim construction or
`
`indefiniteness position or to oppose any other party’s proposed claim construction or indefiniteness
`
`position.
