Attorneys for Plaintiffs and Real-Parties- in-Interest SCEF, LLC and Lynne Levin- Guzman Real-Parties-in-Interest (“Plaintiffs”) respectfully request leave to file a

short surreply in further response to Relator AstraZeneca Pharmaceuticals, LP’s

(“Astra”) petition for writ of mandamus. The proposed surreply is attached hereto

as Exhibit A.

In support of their motion, Plaintiffs state as follows:

• Prior to filing their response to Astra’s mandamus petition, Plaintiffs

amended their pleadings to add voluminous facts supporting venue in

Harrison County.

• In their response to Astra’s mandamus petition, Plaintiffs explained that

(i) under Rule 65 of the Texas Rules of Civil Procedure, the filing of

the amended petition moots Astra’s mandamus petition; (ii) Astra’s 20-

month delay in seeking mandamus triggers laches; and (iii) Astra’s

petition fails because the record before the Court is different from that

at issue in In re Sanofi-Aventis U.S. LLC, 711 S.W.3d 732 (Tex. App.—

15th Dist. 2025, orig. proceeding), including because Astra waived

certain arguments.

• In its reply in support of its mandamus petition, Astra (i) argues that

this Court may not look to the operative pleading to resolve Astra’s

mandamus challenge; (ii) laches does not apply; and (iii) Sanofi is “on

all fours” with this case and waiver does not apply.

1 Plaintiffs did not have an adequate opportunity to respond to Astra’s reply

arguments and thus this Court does not have the benefit of Plaintiffs’ views on these

questions. Plaintiffs respectfully seek leave to file the attached, eight-page surreply.

Plaintiffs sought Astra’s consent to this motion for leave. Astra advised that it

takes no position on the matter.
