Writing About Real Places, Companies, and Products
Question: Do you have to get special permission to include something in your writing? For example, if I mention "Warriors: Into the Wild" by Erin Hunter, or a place such as Lake Mary Highschool, or Red Lobster, in my book. Can I just go ahead and write a scene that takes place or mention that product without permission or do I take a different route? And if I have to get permission, what's the best way to do so?Answer.
This question is difficult to answer without knowing the context (for instance, what you plan to say about these real life places or works) or whether this is a work of fiction or nonfiction. Also, I'm not a lawyer and don't pretend to be an expert on trademarks and copyright law.
That said, if a publisher wants to buy your book, they should have a legal adviser who can clarify such matters and let you know if anything needs to be altered prior to publication.
If you're writing nonfiction, you have the same obligations that journalists have to tell the truth as you are able to discern it, without malicious slander, and to back up your claims with evidence.
If you're writing fiction, you probably don't need to worry too much unless you are saying something defamatory about a corporation or its products, misrepresenting them, or misspelling their names. A simple reference is actually giving free advertising.
However, the issues vary depending on what you're referring to. You should probably not quote copyrighted song lyrics, for example, since your publisher may need to pay a fee to the copyright owner to reproduce them. If you are including living people in your novel, you may need to avoid saying anything that would damage their reputation. Dead, historical figures are generally fair game.
Mentioning real big cities is never a problem. But if your book is set in a real life high school, you probably should change the name so as to not risk offending any students or teachers who think you are writing about them and take offense at the characterization. Ditto for small towns and their residents.
Similarly, you may want to invent a fictitious restaurant just to be on the safe side. Ask yourself if it will really affect your story. I'm guessing that in most cases it won't.
