Is a state law cause of action precluded by federal copyright law?

^5. State law causes of action are preempted to the extent they assert rights equivalent to the exclusive rights protected by federal copyright law. ( Kabehie v. Zoland (2002) 102 Cal.App.4th 513, 517, 125 Cal.Rptr.2d 721.) Defendants do not contend plaintiff's state law claims are preempted by federal copyright law or that the trial court did not otherwise have subject matter jurisdiction over these claims. We express no opinion on the merits of plaintiff's state law claims.
