There are plenty of major writers who can’t abide fan fiction based on their work. They post statements about it on their websites. Orson Scott Card, author of the classic Ender’s Game books, has written, “I will sue, because if I do NOT act vigorously to protect my copyright, I will lose that copyright … So fan fiction, while flattering, is also an attack on my means of livelihood.” Anne Rice is every bit as vehement: “I do not allow fan fiction. The characters are copyrighted. It upsets me terribly to even think about fan fiction with my characters. I advise my readers to write your own original stories with your own characters.”

The legal argument against fan fiction isn’t actually very strong. The scenario Card describes, in which an author’s rights are diminished because he or she doesn’t actively defend them, is associated more with trademark than with copyright. But in practice, a fan-fiction writer who receives a cease-and-desist letter has almost no choice but to comply. No fan wants to go through the bother and expense of litigating against a celebrity or a major corporation. As a result, no definitive legal precedent exists.

But there’s more to argue about than legal niceties. A lot of authors feel emotionally and viscerally that nobody else has any business using their characters. George R.R. Martin, author of A Game of Thrones, writes on his website, “My characters are my children … I don’t want people making off with them, thank you. Even people who say they love my children.” Ursula K. Le Guin, another giant of the fantasy canon, writes, “To me, it’s not sharing but an invasion, literally — strangers coming in and taking over the country I live in, my heartland.”

Copyright law is an exception to our free speech rights, Constitutionally provided as an economic incentive for authors to create works. Since copyright is an exception to our fundamental value of not having the government interfere with our speech without a really good reason, authors and artists should think long and hard about whether this curb on free speech is properly balanced against the emotional connection they have with their work. And Grossman is right; Orson Scott Card’s statement on copyright law is incorrect. Failure to enforce a copyright does not mean you will lose it.
