Case 7:25-cv-00222-DC-DTG Document 93 Filed 05/21/26 Page 1 of 3 IN THE UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF TEXAS MIDLAND-ODESSA DIVISION MALIKIE INNOVATIONS LTD., KEY PATENT INNOVATIONS LTD. Plaintiffs, CASE NO. 7:25-cv-00222-DC-DTG v. JURY TRIAL DEMANDED MARA HOLDINGS, INC. (F/K/A MARATHON DIGITAL HOLDINGS, INC Defendant. NOTICE OF SUPPLEMENTAL AUTHORITY IN SUPPORT OF MARA HOLDINGS, INC.’S MOTION TO STAY PENDING EX PARTE REEXAMINATION Defendant MARA Holdings, Inc. (“MARA”) hereby notifies the Court of supplemental authority in support of MARA’s motion to stay this case pending the results of the ex parte reexaminations of all six of the patents-in-suit (Dkt. 54). As the Court is aware, MARA petitioned the Patent Office to institute ex parte reexaminations on each of the six patents-in-suit, and the Patent Office granted each of those petitions, finding that each petition raised a substantial new question of patentability. Dkt. 79. MARA hereby provides notice that, on May 20, 2026, the Patent Office denied Plaintiffs’ requests for summary termination of the ex parte reexaminations of five of the patents-in-suit. Thus, those pending reexaminations will proceed on the merits. For the Court’s convenience, MARA has attached hereto copies of those decisions as Exhibit A–E. 1 1 Plaintiffs have filed a nearly identical request for a summary termination of the ex parte reexamination proceeding concerning the sixth patent-in-suit. Earlier today, MARA filed a timely opposition to that request, which remains pending. Case 7:25-cv-00222-DC-DTG Document 93 Filed 05/21/26 Page 2 of 3 MARA respectfully requests that the Court take notice of and consider the Patent Office’s denial of Plaintiffs’ request to terminate the ex parte reexaminations. See Dkt. 61 at 4, n. 3 (Plaintiffs asserting that the motion to stay should be denied in part because it intended to request that the Patent Office terminate the reexamination proceedings).
