What is the limitation period for a civil RICO claim under the "injury discovery" rule?

We have continuously followed the "injury discovery" statute of limitations rule for civil RICO claims. See Grimmett v. Brown, 75 F.3d 506, 511 (9th Cir. 1996).³ Under this rule, "the civil RICO limitations period begins to run when a plaintiff knows or should know of the injury that underlies his cause of action." Id. at 510 (internal quotation marks omitted). Thus, the "injury discovery" rule creates a disjunctive twoprong test of actual or constructive notice, under which the statute begins running under either prong.
