Defenses)

(*) indicates a deadline that cannot be changed without an acceptable showing of good 

cause. Good cause is not shown merely by indicating that the parties agree that the 

deadline should be changed.

ADDITIONAL REQUIREMENTS

Mediation: While certain cases may benefit from mediation, such may not be appropriate 

for every case. The Court finds that the Parties are best suited to evaluate whether mediation will 

benefit the case after the issuance of the Court’s claim construction order. Accordingly, the Court 

ORDERS the Parties to file a Joint Notice indicating whether the case should be referred for 

mediation within fourteen days of the issuance of the Court’s claim construction order. As a 

part of such Joint Notice, the Parties should indicate whether they have a mutually agreeable 

mediator for the Court to consider. If the Parties disagree about whether mediation is appropriate, 

the Parties should set forth a brief statement of their competing positions in the Joint Notice.

Summary Judgment Motions, Motions to Strike Expert Testimony, and Daubert 

Motions: For each motion, the moving party shall provide the Court with two (2) hard copies of 

the completed briefing (opening motion, response, reply, and if applicable, sur-reply), excluding 

exhibits, in D-three-ring binders, appropriately tabbed. All documents shall be single-sided and 

Case 2:23-cv-00352-JRG-RSP Document 119 Filed 12/05/24 Page 4 of 6 PageID #:

8432
- 5 -

must include the CM/ECF header. These copies shall be delivered to the Court within three (3) 

business days after briefing has completed. For expert-related motions, complete digital copies of 

the relevant expert report(s) and accompanying exhibits shall be submitted on a single flash drive 

to the Court. Complete digital copies of the expert report(s) shall be delivered to the Court no later 

than the dispositive motion deadline.

Indefiniteness: In lieu of early motions for summary judgment, the parties are directed to 

include any arguments related to the issue of indefiniteness in their Markman briefing, subject to 

the local rules’ normal page limits.

Lead Counsel: The Parties are directed to Local Rule CV-11(a)(1), which provides that 

“[o]n the first appearance through counsel, each party shall designate a lead attorney on the 

pleadings or otherwise.” Additionally, once designated, a party’s lead attorney may only be 

changed by the filing of a Motion to Change Lead Counsel and thereafter obtaining from the Court 

an Order granting leave to designate different lead counsel. The true lead counsel should be 

designated early and should not expect to parachute in as lead once the case has been largely 

developed. 

Motions for Continuance: The following will not warrant a continuance nor justify a 

failure to comply with the discovery deadline: 

(a) The fact that there are motions for summary judgment or motions to dismiss pending;

(b) The fact that one or more of the attorneys is set for trial in another court on the same day,

unless the other setting was made prior to the date of this order or was made as a special

provision for the parties in the other case;

(c) The failure to complete discovery prior to trial, unless the parties can demonstrate that it

was impossible to complete discovery despite their good faith effort to do so.

Amendments to the Docket Control Order (“DCO”): Any motion to alter any date on

the DCO shall take the form of a motion to amend the DCO. The motion to amend the DCO shall 

include a proposed order that lists all of the remaining dates in one column (as above) and the 

proposed changes to each date in an additional adjacent column (if there is no change for a date 

the proposed date column should remain blank or indicate that it is unchanged). In other words, 

the DCO in the proposed order should be complete such that one can clearly see all the remaining 

deadlines and the changes, if any, to those deadlines, rather than needing to also refer to an earlier 

version of the DCO.

Proposed DCO: The Parties’ Proposed DCO should also follow the format described 

above under “Amendments to the Docket Control Order (‘DCO’).” 

Joint Pretrial Order: In the contentions of the Parties included in the Joint Pretrial Order, 

the Plaintiff shall specify all allegedly infringed claims that will be asserted at trial. The Plaintiff 

shall also specify the nature of each theory of infringement, including under which subsections of 

35 U.S.C. § 271 it alleges infringement, and whether the Plaintiff alleges divided infringement or 

infringement under the doctrine of equivalents. Each Defendant shall indicate the nature of each

Case 2:23-cv-00352-JRG-RSP Document 119 Filed 12/05/24 Page 5 of 6 PageID #:

8433
- 6 -

theory of invalidity, including invalidity for anticipation, obviousness, subject-matter eligibility, 

written description, enablement, or any other basis for invalidity. The Defendant shall also specify 

each prior art reference or combination of references upon which the Defendant shall rely at trial, 

with respect to each theory of invalidity. The contentions of the Parties may not be amended, 

supplemented, or dropped without leave of the Court based upon a showing of good cause. The 

Parties in a case which has been consolidated for pre-trial purposes and which is moving towards 

a separate trial on the merits (subsequent to pre-trial) shall file, as an exhibit to the parties’ Joint 

Pretrial Order, a list identifying all docket entries from the lead case that relate to the applicable 

member case.

Trial: All parties must appear in person at trial. All non-individual (including but not 

limited to corporate) parties must appear at trial through the presence in person of a designated 

representative. Once they have appeared, any representative of a non-individual party shall not be 

replaced or substituted without express leave of Court.
