Submitted November 12, 2025**

indifference and retaliation. We have jurisdiction under 28 U.S.C. § 1291. We
review de novo. Wilhelm v. Rotman, 680 F.3d 1113, 1118 (9th Cir. 2012)
(dismissal under 28 U.S.C. § 1915A); Watison v. Carter, 668 F.3d 1108, 1112 (9th
Cir. 2012) (dismissal under 28 U.S.C. § 1915(e)(2)(B)). We affirm.
The district court properly dismissed Richardson’s individual capacity
claims because Richardson failed to allege facts sufficient to show that any
defendant was deliberately indifference to his serious medical needs or took
adverse action against him because of his protected conduct. See Brodheim v. Cry,
584 F.3d 1262, 1269 (9th Cir. 2009) (setting forth elements of a retaliation claim in
the prison context); Toguchi v. Chung, 391 F.3d 1051, 1057-58 (9th Cir. 2004)
(explaining that prison officials act with deliberate indifference only if they know
of and disregard an excessive risk to the prisoner’s health, and that a difference of
medical opinion is insufficient to establish deliberate indifference).
The district court properly dismissed Richardson’s official capacity claims
as barred by sovereign immunity. See Brown v. Cal. Dep’t of Corr., 554 F.3d 747,
752 (9th Cir. 2009) (explaining that the State of California enjoys Eleventh
Amendment immunity with respect to § 1983 claims in federal court).
The district court properly dismissed as moot Richardson’s claims for
injunctive relief. See Dilley v. Gunn, 64 F.3d 1365, 1368-69 (9th Cir. 1995)
(explaining that a prisoner’s transfer to a different state prison moots claims for
2 24-1247
injunctive relief absent certain exceptions).
AFFIRMED.
