What are the poem copyright laws in Oregon?

We don't have specific Oregon laws for poetry per se, other than the law establishing and governing the office of our State Poet Laureate. Copyright is a federal law. You have a copyright in a poem the moment you complete it. If you intend to use the poetry publicly, you should consider registering your copyright with the US Copyright office for increased protection of your work. If you are thinking of using someone else's poem, you will likely need to license the poem from its copyright holder (usually the author, sometimes a publisher).

Copyright law is based on the federal copyright statute, not on state-by-state laws. For more info, go to copyright.gov.
