…many commentators, and indeed, many fans themselves, operate on the rueful assumption that fan fiction does in fact infringe copyright.
Undaunted by this, Rebecca Tushnet, a professor of law at Georgetown University, and a keen fan fiction writer herself, wants to take fan fiction out of the legal shadows where it has operated, more or less at sufferance, for decades, and carve out a legal place for it within the US doctrine of fair use. She has recently helped found the Organization for Transformative Use, with the mandate to establish fan fiction within the parameters of legal, non-infringing use.
