NOTICE of Voluntary Dismissal by Sega Corporation, Sega of America, Inc. as to a certain defendant

17

May 29, 2026

MINUTE entry before the Honorable John F. Kness: Plaintiff has filed a "Notice of Dismissal under Rule 41(a)(1)" [16]. Because the Notice of Dismissal was filed before the opposing party served either an answer or a motion for summary judgment, the case is dismissed without prejudice consistent with the terms of the Notice and by operation of Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure. See Nelson v. Napolitano, 657 F.3d 586, 587 (7th Cir. 2011) (Rule 41(a)(1)(A) notice of dismissal "is self-executing and effective without further action from the court"). Each party is to bear its own fees and costs. The motion to seal [3], which Plaintiff withdrew [13], is dismissed. The hearing set for 6/1/2026 is stricken. Civil case terminated. Mailed notice.
