August 24, 2026 	September 14, 2026
Hearing on Summary Judgment Motions 	To be set by the
Court
October 30, 2026
This requested schedule extension is based on Plaintiffs’ request for more time to review
Defendants’ recent document productions. On January 5, 2026, the Court ordered Defendants “to
produce ‘All Documents and Communications Concerning Your acquisition, use, storage,
retention, distribution, and deletion’ of the RedPajama – Books and Books3 datasets.” Dkt. 242 at
4. 	Pursuant to the Court’s Order, Defendants produced an additional ten terabytes of data on
January 30, 2026. 	Plaintiffs requested additional time to allow their technical experts sufficient
time to analyze and review this data produced by Defendants. Plaintiffs’ technical expert estimated
that reviewing 400 gigabytes of data would entail an estimated six hours to complete in addition to
follow up review, requiring an additional three weeks of analysis to review the ten terabytes
produced.
The Parties have previously stipulated to extend all case deadlines three times, which the

STIP. AND [PROPOSED] ORDER TO
AMEND CASE SCHEDULE 2 	Master File Case No.: 3:24-cv-01451-CRB
Court ordered on February 19, 2025, April 23, 2025, and September 4, 2025. See Dkts. 82, 111
and 172. The Parties previously stipulated to a limited adjustment of the expert discovery deadlines
to account for the holiday season, which the Court ordered on December 31, 2025. 	Dkt. 240.
Plaintiffs moved to amend the case schedule on November 18, 2025, Dkt. 191, and Defendants
contested Plaintiffs’ motion, Dkt. 198. 	The Court granted Plaintiffs’ motion to amend the case
schedule on December 31, 2025, setting the current case schedule. Dkt. 238.
This extension is without prejudice to, and does not bear upon, the Parties’ respective
positions and arguments regarding whether discovery disputes may be presented to the Court.
Defendants maintain that this extension applies solely to the deadlines set forth in this stipulation
and does not authorize Plaintiffs to conduct any additional fact discovery or raise new disputes
related to fact discovery. Defendants maintain their right to object to any use of this extension to
raise new discovery issues. Plaintiffs do not seek to reset the fact discovery deadlines but reserve
their rights under the Federal Rules, the Local Rules, and the Court’s Orders to raise issues with
Defendants’ discovery for good cause.
IT IS SO STIPULATED.
