Marketing and Fair Use
<p>The company I work for sells several products.  One has a title that lines up very well in the One Ring poem from Tolkien's LOTR.  I would essentially be replacing the phrase One Ring with the product title, and either leaving the rest the same, or perhaps a slight modification to the last line.  Is there any way this falls under fair use or would I need to get permission to do this?</p>

<p>The product in no way relates to anything Tolkien or fantasy or fiction for that matter. I don't believe it could be seen as an endorsement.</p>

<p>You breach copyright when you substantially copy <em>or create a derivative work from</em> a literary work. A poem is a literary work; you need permission. From The Tolkien estate you won't get it.</p>
