Could I write a new Frankenstein book since it&#39;s public domain?
<p>I was largely just wondering about this as there are a number of very fun, interesting things that could be done with the character.</p>

<p>Mary Shelley's <a href="https://en.wikipedia.org/wiki/Frankenstein" rel="noreferrer">Frankenstein</a> is indeed public domain so you are free to use that character.</p>

<p>However, a lot of what we think of as "Frankenstein" is not Mary Shelly, for example, the iconic Frankenstein look dates from the 1931 <a href="https://en.wikipedia.org/wiki/Frankenstein_(1931_film)" rel="noreferrer">film</a> which may still be under copyright.</p>

<p>You can use elements that are public domain, you can't use elements that aren't.</p>
